OBJECTIVES/OBJECTIVE:This study sought to minimize the risk of permanent pacemaker implantation (PPMI) with contemporary repositionable self-expanding transcatheter aortic valve replacement (TAVR). BACKGROUND:Self-expanding TAVR traditionally carries a high risk of PPMI. Limited data exist on the use of the repositionable devices to minimize this risk. METHODS:At NYU Langone Health, 248 consecutive patients with severe aortic stenosis underwent TAVR under conscious sedation with repositionable self-expanding TAVR with a standard approach to device implantation. A detailed analysis of multiple factors contributing to PPMI was performed; this was used to generate an anatomically guided MInimizing Depth According to the membranous Septum (MIDAS) approach to device implantation, aiming for pre-release depth in relation to the noncoronary cusp of less than the length of the membranous septum (MS). RESULTS:Right bundle branch block, MS length, largest device size (Evolut 34 XL; Medtronic, Minneapolis, Minnesota), and implant depth > MS length predicted PPMI. On multivariate analysis, only implant depth > MS length (odds ratio: 8.04 [95% confidence interval: 2.58 to 25.04]; p < 0.001) and Evolut 34 XL (odds ratio: 4.96 [95% confidence interval: 1.68 to 14.63]; p = 0.004) were independent predictors of PPMI. The MIDAS approach was applied prospectively to a consecutive series of 100 patients, with operators aiming to position the device at a depth of < MS length whenever possible; this reduced the new PPMI rate from 9.7% (24 of 248) in the standard cohort to 3.0% (p = 0.035), and the rate of new left bundle branch block from 25.8% to 9% (p < 0.001). CONCLUSIONS:Using a patient-specific MIDAS approach to device implantation, repositionable self-expanding TAVR achieved very low and predictable rates of PPMI which are significantly lower than previously reported with self-expanding TAVR.

Rodés-Cabau, Josep; Williams, Mathew R; Wijeysundera, Harindra C; Kereiakes, Dean J; Paradis, Jean-Michel; Staniloae, Cezar; Saric, Muhamed; Radhakrishnan, Sam; Wilson, Robert F; Kubo, Spencer H
BACKGROUND:While most self-expanding transcatheter valves are repositionable, only one fully retrievable valve is currently available. The Meridian valve is a new self-expanding valve with full retrievability properties. The objective of our study was to evaluate the early feasibility, preliminary safety, and efficacy of transcatheter aortic valve replacement with the HLT Meridian valve (HLT, Inc). METHODS:This was a multicenter early feasibility study including patients with severe aortic stenosis at high surgical risk undergoing transfemoral transcatheter aortic valve replacement with the 25-mm Meridian valve. All serious adverse events were adjudicated by an independent clinical events committee according to Valve Academic Research Consortium-2 criteria. Echocardiography data were assessed by an independent echocardiography core laboratory. RESULTS:A total of 25 patients (mean age, 85±6 years; 80% of men) were included. The valve was successfully implanted in 22 (88%) patients (annulus too large and extreme horizontal aorta in 2 and 1 unsuccessful cases, respectively). Valve retrieval because of an initial nonadequate positioning was attempted and successfully performed in 10 (40%) patients. Echocardiography post-transcatheter aortic valve replacement showed a low mean residual gradient (10±4 mm Hg) and the absence of moderate-severe aortic regurgitation (none-trace and mild aortic regurgitation in 76% and 24% of patients, respectively). Mortality at 30 days was 8%, with no cases of disabling stroke, valve embolization, or major/life-threatening bleeding complications. At 6-month follow-up, the cumulative mortality rate was 12%, with no changes in echocardiographic parameters and no cases of valve dysfunction. The majority of patients (89%) were in New York Heart Association class I-II at 6 months. CONCLUSIONS:Transcatheter aortic valve replacement with the Meridian valve was feasible and associated with acceptable early and 6-month clinical results. Valve retrieval after full valve deployment was successfully performed in all attempted cases, and valve performance was excellent, with low residual gradients, no cases of moderate-severe aortic regurgitation, and none-trace residual aortic regurgitation in the majority of patients.

Shah, Binita; Villablanca, Pedro A; Vemulapalli, Sreekanth; Manandhar, Pratik; Amoroso, Nicholas S; Saric, Muhamed; Staniloae, Cezar; Williams, Mathew R
BACKGROUND:Renal disease is associated with poor prognosis despite guideline-directed cardiovascular therapy, and outcomes by sex in this population remain uncertain. METHODS AND RESULTS/RESULTS:Patients (n=5213) who underwent a MitraClip procedure in the National Cardiovascular Data Registry Transcatheter Valve Therapy registry were evaluated for the primary composite outcome of all-cause mortality, stroke, and new requirement for dialysis by creatinine clearance (CrCl). Centers for Medicare and Medicaid Services-linked data were available in 63% of patients (n=3300). CrCl was <60 mL/min in 77% (n=4010) and <30 mL/min in 23% (n=1183) of the cohort. Rates of primary outcome were higher with lower CrCl (>60 mL/min, 1.4%; 30-<60 mL/min, 2.7%; <30 mL/min, 5.2%; dialysis, 7.8%; P<0.001), and all low CrCl groups were independently associated with the primary outcome (30-<60 mL/min: adjusted odds ratio, 2.32; 95% CI, 1.38-3.91; <30 mL/min: adjusted odds ratio, 4.44; 95% CI, 2.63-7.49; dialysis: adjusted hazards ratio, 4.52; 95% CI, 2.08-9.82) when compared with CrCl >60 mL/min. Rates of 1-year mortality were higher with lower CrCl (>60 mL/min, 13.2%; 30-<60 mL/min, 18.8%; <30 mL/min, 29.9%; dialysis, 32.3%; P<0.001), and all low CrCl groups were independently associated with 1-year mortality (30-<60 mL/min: adjusted hazards ratio, 1.50; 95% CI, 1.13-1.99; <30 mL/min: adjusted hazards ratio, 2.38; 95% CI, 1.78-3.20; adjusted hazards ratio: dialysis, 2.44; 95% CI, 1.66-3.57) when compared with CrCl >60 mL/min. CONCLUSIONS:The majority of patients who undergo MitraClip have renal disease. Preprocedural renal disease is associated with poor outcomes, particularly in stage 4 or 5 renal disease where 1-year mortality is observed in nearly one-third. Studies to determine how to further optimize outcomes in this population are warranted.

Systematic Transfemoral Transarterial Transcatheter Aortic Valve Replacement in Hostile Vascular Access
Staniloae, C S; Jilaihawi, H; Amoroso, N S; Ibrahim, H; Hisamoto, K; Sin, D N; Lee, H; Du, R; Zhao, Z -G; Neuburger, P J; Williams, M R
Background: Traditionally, hostile peripheral access patients undergo TAVR via alternative access. We describe the "transfemoral-first" (TF-1) approach in patients with hostile peripheral access. Method(s): Clinical and procedural data were obtained for all TAVR cases performed from August 2016 to July 2017. Computed tomography was used to assess iliofemoral arteries. Patients were divided into three femoral access groups: routine, hostile, and prohibitive. We attempted TF access in all patients with routine and hostile access. Hostile access was defined as: (1) arterial segments with diameter <5.0 mm; or (2) <5.5 mm with severe calcification (270-360degree arc of calcification) or severe tortuosity; or (3) severe tortuosity along with severe calcification. Outcomes of the hostile access group patients who underwent TF-1 are described. The primary endpoint was successful completion of the procedure without major complications by the intended route. The secondary endpoints were procedural complications as defined by the VARC-2 criteria. Result(s): Of 377 consecutive patients, 99.5% underwent TF-1 TAVR; two patients (0.4%) had prohibitive access. Twenty-eight (7.4%) patients had hostile access with access side mean minimal lumen diameter of 4.7 mm (range 3.8-5.4 mm). Twenty-six (92.8%) were successfully treated with TF-1 strategy. Twelve (42.8%) of the 26 patients underwent preparatory endovascular treatment prior to TAVR during the same operating room visit. There was 1 (3.5%) major or life-threatening bleeding complication and 2 (7.1%) major vascular complications. There were no deaths or strokes. Conclusion(s): Using the safe and effective endovascular approach, TF-1 TAVR is feasible for all-comers-including those with hostile access-with low complication rate. Larger studies are warranted to validate this approach.

Shah, Binita; McDonald, Daniel; Paone, Darien; Redel-Traub, Gabriel; Jangda, Umair; Guo, Yu; Saric, Muhamed; Donnino, Robert; Staniloae, Cezar; Robin, Tonya; Benenstein, Ricardo; Vainrib, Alan; Williams, Mathew R
BACKGROUND:Transcatheter aortic valve replacement (TAVR) for low gradient (LG) severe aortic stenosis (AS) with preserved left ventricular ejection fraction (LVEF) remains an area of clinical uncertainty. METHODS:Retrospective review identified 422 patients who underwent TAVR between September 4, 2014 and July 1, 2016. Procedural indication other than severe AS (n = 22) or LVEF <50% (n = 98) were excluded. Outcomes were defined by valve academic research consortium two criteria when applicable and compared between LG (peak velocity <4.0 m/s and mean gradient <40 mmHg; n = 73) and high gradient (HG) (n = 229) groups. The LG group was further categorized as low stroke volume index (SVI) (n = 41) or normal SVI (n = 32). Median follow-up was 747 days [interquartile range 220-1013]. RESULTS: = 0.39). CONCLUSION/CONCLUSIONS:Patients with preserved LVEF undergoing TAVR for severe AS with LG, including LG with low SVI, have no significant difference in adverse outcomes when compared to patients with HG.

Ascending Aortic Stenting for Acute Supra-aortic Stenosis from Graft Collapse
Lader, Joshua M; Smith, Deane E; Staniloae, Cezar; Fallahi, Arzhang; Iqbal, Sohah N; Galloway, Aubrey C; Williams, Mathew R
A 78 year-old man with remote type-A dissection presented with acute-onset dyspnea. Twenty-two years prior, treatment for his aortic disease required replacement of ascending and arch aneurysms with a Dacron graft using graft inclusion technique. He presented currently in cardiogenic shock. Echocardiography demonstrated new severe hypokinesis of all apical segments. Left-heart catheterization revealed a 120mmHg intra-graft gradient. CT arteriography was unrevealing, but intra-aortic ultrasound demonstrated critical intra-graft stenosis. A Palmaz stent was deployed in the stenotic region with gradient resolution. He later underwent aortic root replacement and ascending aneurysm repair (Bio-Bentall technique) and is doing well at 24 months.
