Exclusion of the left atrial appendage with a novel device: Early results of a multicenter trial. Report of the guideline development subcommittee of the American Academy of neurology. Device malfunctions occurred in 23 patients. Additionally, the hemorrhagic stroke rate in the control group corresponded to a higher rate than observed in contemporary anticoagulation clinical trials. The term “allowable amount” refers to the total amount a regulation or private health plan determines a provider should be paid. Based on the evidence and public comments, CMS is modifying the physician criteria accordingly, to include interventional cardiologist(s), electrophysiologist(s), or cardiovascular surgeon who has received training prescribed by the manufacturer on the safe and effective use of the device prior to performing LAAC and must have performed = 25 interventional cardiac procedures that involve transeptal puncture through an intact septum over a two year period, and continues to maintain this experience with at least 12 being LAAC over a two year period. Two comments were submitted by joint professional societies, one from the AHA/ASA and the other by ACC/HRS/SCAI. Stoddard MF, Dawkins PR, Prince CR, Ammash NM. Outcome of  LAA occlusion. Net clinical benefit of warfarin in patients with atrial fibrillation. London: National Institute of Health and Care Excellence (UK);2014:420. The advisory panel voted for approval; however in February 2014 the FDA received updated follow-up data from the PREVAIL trial that showed additional ischemic strokes in WATCHMAN device subjects, calling into question the mechanism of the device. The evidence is insufficient to permit conclusions about the effect of the percutaneous LAAC technologies on health outcomes. AF is a heart arrhythmia characterized by disorganized atrial electrical activity and a loss of coordinated atrial contraction. FDA Table 48 compares major bleeding results between arms. CMS accepts these recommendations from the joint professional societies since they represent the best available evidence for this device. 2013;61:2551-6. If the inclusion and exclusion criteria are expected to have a negative effect on the recruitment or retention of underrepresented populations, the protocol must discuss why these criteria are necessary. 2015;128: 260-7. FDA Table 1 provides a comparison of events for the previously reviewed dataset (FDA panel December 2013, data lock at January 2013) and the updated dataset (FDA panel October 2014, data lock at June 2014). This presentation of evidence focuses upon whether current percutaneous implanted device randomized controlled trials (RCTs) are adequate to draw conclusions about health outcomes for reduction of stroke and thromboembolism, as well as whether the body of evidence is generalizable to the Medicare population. 2007). 2010). Prepared for the April 23, 2009 meeting of the Circulatory System Devices Advisory Panel. 2014;64:565-72. endstream endobj startxref The subject died 7 months later. New sites and new operators were included. The Amplatzer™ Cardiac Plug (St. Jude Medical, Minneapolis, MN) has not yet been approved by FDA. This downward trend has occurred in tandem with cardiovascular risk factor control interventions such as hypertension control and smoking cessation programs. The efficacy endpoint was defined as the composite of cardiovascular and unexplained deaths, neurologic events (ischemic and hemorrhagic stroke, TIAs), and SE. Antiplatelet monotherapy is associated with a 21% relative reduction in risk of nonfatal stroke (ischemic and hemorrhagic) compared with no treatment and a 50%-60% relative increase in the risk of major extracranial bleeding (pooled estimate). JAMA 2014;312(19):1988-1998. Alli O, Doshi S, Kar S, et al. The FDA worked with the sponsor to design a new clinical study, the PREVAIL trial. Separate discussions in the protocol may be necessary for populations eligible for Medicare due to age, disability or Medicaid eligibility. JAMA. While thinning the blood with anticoagulant medications has been proven to prevent strokes, percutaneous LAA closure (LAAC) has been studied as a non-pharmacologic alternative for patients with AF. Changes in functional outcome over the first year after stroke: an observational study from the Swedish Stroke Register. The Framingham Heart Study. Percutaneous closure of the left atrial appendage versus warfarin therapy for prevention of stroke in patients with atrial fibrillation: a randomized non-inferiority trial. For the 2621 pt-yr analysis, the primary safety event rate was 3.6% for the device group and 3.1% for the control group. CMS Response: For LAAC for patients with NVAF, this decision describes the criteria that must be met to be covered by Medicare. Many said patients with relative contraindications have the most to gain. 2014;5(1):21-37. Evidence-based decision tools are available for helping patients reach a decision about whether to take an anticoagulant to reduce their risk of stroke. N Engl J Med. Responses to FDA’s questions were provided on May 2, 2014. h�bbd``b`��kA�%�`9"XA\ � $��ċeL�le .#���? 2014). The second RCT, which incorporated the first trial’s results as a Bayesian prior, did not meet noninferiority criteria for its first principal composite outcome (stroke, death, and embolism). Am J Med. Ann Intern Med. Atrial fibrillation patient with indication for OAC for stroke/embolism presentation (CHA2DS2-VASc > 1). Meta-analysis of efficacy and safety of new oral anticoagulants (Dabigatran, Rivaroxaban, Apixaban) versus warfarin in patients with atrial fibrillation. This manufacturer-funded trial enrolled patients with NVAF and a CHADS2 of =2 or 1 and another risk factor (female age =75, baseline ejection fraction = 30% but <35%, age 65 to 74 years and either diabetes or coronary disease, and age =65 years with congestive heart failure). JAMA. 2015;1-12. No new trials were mentioned. A variety of other risk factors and biomarkers that are associated with AF including diabetes, obesity, genetic factors, smoking, and inflammation (January et al. Avoidance of Major Bleeding with WATCHMAN LAA Closure Compared with Long-Term Anticoagulation: A Pooled analysis of PROTECT AF and PREVAIL trials. (http://guidance.nice.org.uk/CG180/PatientDecisionAid/pdf/English) (http://www.acponline.org/patients_families/products/brochures/afib_booklet.pdf)(Eckman et al. These comments are noted: Clinical narratives were reviewed to investigate the increasing number of events observed in the device group. Table 1. That section includes a requirement that the Secretary assure that AHRQ research priorities under Section 1142 appropriately reflect the needs and priorities of the Medicare program. All except five were unrelated to LAAC but all were reviewed and all relevant studies were added to the decision memo. Information concerning this therapy in these patients is of great interest. 2014;7:458-64. 1999;131:927-34. 2014;45:426-431. A Bayesian Hierarchical model is used for evaluation. 2009;40:1410-1416. Management of antiplatelet and anticoagulant therapy in patients with atrial fibrillation in the setting of acute coronary syndromes or percutaneous coronary interventions. Page 1991. Depending on the type of procedure and device use, close collaboration may be required between procedural specials, physician echocardiographers, sonographers, radiologists, hematologists, neurologists, and cardiac surgeons to ensure proper patient selection, evaluation, and execution of LAA occlusion. Clinicians should counsel all patients with NVAF that the decision to use antithrombotics must be made only after the potential benefit from the stroke risk reduction has been weighed against the potential harm from the increased risk of major bleeding. Shared decision making has the patient at the center and is much more structured, evidence-based and importantly interactive with bilateral exchange of information compared to informed consent. “The rate of subject withdrawal, particularly the disparity in withdrawal rates between treatment groups, could lead to bias against the control group and favoring of the device group for the long-term event rate comparisons presented below, considering that the hazard rates decrease over time.”, The primary effectiveness endpoint was met for statistical noninferiority. Mean follow-up time was 1.8 (1.0-2.8) years for a total of 103.2 pt-yrs. Methodologists have developed criteria to determine weaknesses and strengths of clinical research. Effect of clopidogrel added to aspirin in patients with atrial fibrillation. A few comments suggested the clinician weigh the risks and benefits for the patient without a decision aid. An intensive care facility with staff trained to provide postprocedural observation and management.”, “The ACC, HRS, and Society for Cardiovascular Angiography and Interventions have published recommendations for training in electrophysiology or interventional techniques, but these recommendations do not provide specific guidance for LAA occlusion devices. Moreover, with limited exceptions, the expenses incurred for items or services must be "reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member." Prevalence of residual left atrial thrombi among patients with acute thromboembolism and newly recognized atrial fibrillation. PREVAIL results at the second FDA panel meeting: Longer-term follow-up data from PROTECT AF examined at the second FDA advisory panel is noted for the following: The third advisory panel meeting to discuss updated datasets from the PREVAIL and PROTECT AF trials was in October 2014. Plicht B, Konorza TFM, Kahlert P, et al. for payment. J Thorac Cardiovasc Surg. Price MJ, Gibson DN, Yakubov SJ, et al. 30 day comment period commenced. A second principal outcome (stroke and embolism after 7 days) met noninferiority criteria in 1 of 2 analyses and a performance goal for short-term complication rate. Estimates on the incidence and prevalence of AF vary but it is known that AF, similar to stroke, increases with age. WATCHMAN LAA Closure Technology, Atritech, Inc. The HAS-BLED score is guideline recommended in European and Canadian guidelines to assess bleeding risk and is supported in the professional society consensus statement that includes a numeric recommendation. 2005;36:1330-1340. The absolute stroke risk is highest among patients with NVAF and a history of stroke and TIA (aggregated absolute risk about 10%/y). The search was performed from February to December 28, 2015. Device-related infection among patients with pacemakers and implantable defibrillators: incidence, risk factors, and consequences. AF is the most common sustained heart rhythm disturbance and the incidence increases with age. While it is noted that difficulties with the non-homogeneous rate can’t be overcome, both analyses were supportive of the two-fold noninferiority assumption. Association between atrial fibrillation and silent cerebral infarctions. 10. The primary endpoint was defined as any thromboembolic complication and/or any bleeding complication. Ansell J, Hirsh J, Hylek E, Jacobson A, Crowther M, Palareti G. Pharmacology and management of the vitamin K antagonists. 1996;10:1765-69. This table depicts reasons for discontinuation of warfarin in the control arm and the number of patients in each category. The proportion of patients classified as lost to follow-up was similar in both groups (4.5% in the device group versus 2.8% in the warfarin group). provides an update of the current definition of stroke: Page 2066. Time in therapeutic window in the warfarin group was given as 70%. In the Framingham cohort, 23.5% of strokes were felt to occur as a direct result of AF in 80-89 year olds (Wolf et al. Left atrial appendage devices for stroke prevention in atrial fibrillation. 2006;151:956-961. Möbius-Winkler S, Majunke N, Sandri M, et al. CMS Response: We disagree with the commenters.

A modification of the Elixhauser comorbidity measures into a point system for hospital death using administrative data. Such studies may meet this requirement only if the disease or condition being studied is life threatening as defined in 21 CFR §312.81(a) and the patient has no other viable treatment options. Antithrombotic therapy and prevention of thrombosis, 9th ed: American College of Chest Physicians Evidence-based clinical practice guidelines. They included suggested CED criteria to be considered. 2012;35(S1):21-27. Stroke prevention activities aim to reduce risk. 2009;360:2066-78. The June 14 dataset for the first primary endpoint showed an increased difference in the 18 month rate ratio and the posterior probability of noninferiority was more distant from the success criterion. Onalan O, Crystal E. Left atrial appendage exclusion for stroke prevention in patients with nonrheumatic atrial fibrillation. Holmes DR, Reddy VK, Turi ZG, Doshi SK, Sievert H, Buchbinder M, Mullin CM, Sick P, for the PROTECT AF Investigators. Cardioembolic stroke: an update.

The study design is methodologically appropriate and the anticipated number of enrolled subjects is sufficient to answer the research question(s) being asked in the National Coverage Determination. Circulation. Reddy VY, Mobius-Winkler S, Miller M, Neuzil P, Schuler G, Wiebe J, Sick P, Sievert H.  Left atrial appendage closure with the WATCHMAN device in patients with a contraindication for oral anticoagulation: ASA Plavix feasibility study with WATCHMAN left atrial appendage closure technology (ASAP Study). One of the goals of our determination process is to assess health outcomes. Censoring at time of last follow-up occurred if patients were lost to follow-up or if patients had an event. Twenty-two references that were not previously reviewed were cited in public comments. The registry’s NCT number must be recorded on the claim. Amplatzer left atrial appendage occlusion: single center 10-year experience. Lip GYH. One subject did not have protocol required imaging confirmation. A serious adverse event was defined as a medical condition that results in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, or resulted in persistent or significant disability/incapacity. 2005). Specifically, the joint professional society statement states that a high score on CHADS2 or CHA2DS2-VASc should be required and defined and gave a recommendation of CHADS2=2 or CHA2DS2-VASc score=3. CHEST. Miller CS, Grandi SM, Shimony A, Filion KB, Eisenberg MJ. Nine patients were found to have thrombus on the device without embolization. In addition, enrollment in the CAP2 registry was suspended pending a complete analysis of the potential ischemic stroke signal in PREVAIL. For example, use of adjunctive medical therapy between the treatment groups was different. “It is therefore expected that stroke prevention in AF in general, and LAA occlusion in particular, will be a collaborative effort of physician and non-physician experts that may include electrophysiologists, interventional cardiologist, and neurologists, imaging experts, primary care providers, cardiac surgeons, and others.”  “The current pool of trained, experienced operators consists largely of those who have participated in industry-sponsored clinical trials. CMS Response:  We disagree. Percutaneous left atrial appendage closure for stroke prevention in patients with atrial fibrillation: an assessment of net clinical benefit. A MEDCAC meeting was not convened on this issue. J Card Surg. The authors note that the procedure is a high-risk intervention and requires specific cognitive and technical skillsets. 2051 et seq.) Thrombus was identified on the device in 15 patients, one of whom had a cerebral ischemia endpoint. SentreHeart, Inc. met with CMS to discuss the LARIAT® procedure. Fourth planned interim analysis. 2014 AHA/ACC/HRS guideline for the management of patients with atrial fibrillation: executive summary: a report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines and the Heart Rhythm Society. About 20% of enrolled subjects had early exit from the study. 2009). Device recapture rate decreased significantly in PREVAIL compared to PROTECT AF. Comment:  One commenter noted the device is extremely cost-effective in comparison to warfarin and NOACs. Limitations with current medical therapies have led to interest in the idea of LAA exclusion to reduce the risk of thromboembolism. It is important to note that the terms left atrial appendage closure (LAAC) and left atrial appendage occlusion (LAAO) are used interchangeably throughout this decision memorandum. Additional relevant variables are treatment regimens (dosage, timing and route of administration), co-interventions or concomitant therapies, and type of outcome and length of follow-up. Percutaneous closure of the left atrial appendage versus warfarin therapy for prevention of stroke in patients with atrial fibrillation: a randomised non-inferiority trial. We appreciate the additional evidence and clinical perspectives provided by the public commenters. Use of contemporaneous control groups (rather than historical controls) in order to ensure comparability between the intervention and control groups. An improved health outcome is one of several considerations in determining whether an item or service is reasonable and necessary. P130013. 2. Doi: 10/1016/j.jacc.2015.04.025, The authors conclude, "In patients with NVAF at increased risk for stroke or bleeding who are candidates for chronic anticoagulation, LAAC results in improved rates of hemorrhagic stroke, cardiovascular/unexplained death, and nonprocedural bleeding compared to warfarin. Throughout this document we use numerous acronyms, some of which are not defined as they are presented in direct quotations. National coverage determinations (NCDs) are determinations by the Secretary with respect to whether or not a particular item or service is covered nationally by Medicare (§1869(f)(1)(B) of the Act). In prevention of thromboembolic events in NVAF, the primary focus is risk reduction. FDA WATCHMAN® LAA closure technology post approval study proposal-acute study. Prepared for the October 8, 2014 meeting of the Circulatory System Devices Advisory Panel. P080022. Both trials were designed as non-inferiority trials so statements about superiority are not supportable. Novel oral anticoagulant use among patients with atrial fibrillation hospitalized with ischemic stroke or transient ischemic attack. The study protocol explicitly discusses how the results are or are not expected to be generalizable to affected beneficiary subpopulations. Stroke is a leading cause of death and functional impairment. JAMA 2015;313(19):1950-1962. Despite warfarin being effective in stroke prevention, warfarin discontinuation rates may be as high as 38% a year, and about 14-44% of at-risk patients are said to be ineligible for treatment (Wrigley and Lip 2009) (Gomes et al. Study discontinuation rates were 15.3 % (71/463) in the device group and 22.5% (55/244) in the warfarin group. Stöllberger C, Schneider B, Finsterer J. It is noted that device patients remained on warfarin 19% (600 pt-yrs) and 23% (900 pt-yrs) of follow-up time. FDA Executive Summary Memorandum. 2014;32:601-625. The Department of Justice published revised regulations for Titles II and III of the Americans with Disabilities Act of 1990 “ADA” in the Federal Register on September 15, 2010. Major adverse events were defined as events that were fatal, life-threatening, needed hospitalization, or prolongation of current hospitalization or led to considerable disability. This was done to include a higher risk group than patients in PROTECT AF. The following is a representative list of study designs (some of which have alternative names) ranked from most to least methodologically rigorous in their potential ability to minimize systematic bias: When there are merely associations but not causal relationships between a study’s variables and outcomes, it is important not to draw causal inferences.
