Long ‐term pacemaker dependency and impact of pacing on mortality following transcatheter aortic valve replacement with the LOTUS valve

ConclusionOnly 38% of Lotus recipients who require a PPM following TAVR with the Lotus valve remain pacing dependent at one year.

AbstractPurpose of ReviewAortic stenosis is the most prevalent valvular heart disease. The purpose of this paper is to review the epidemiology, pathophysiology, and diagnosis of aortic valve stenosis.Recent FindingsThe diagnosis of aortic stenosis has evolved over time. Originally diagnosed with cardiac catheterization and echocardiography, more advance imaging techniques including computed tomography, magnetic resonance imaging, and 3D printing have improved our understanding of the physiology and hemodynamic effects of aortic stenosis.SummaryValvular heart disease affects a broad patient population, and the most common f...

CONCLUSIONS: NFLG-AS was the most prevalent form of LG severe AS and was associated with adequate left ventricular compensation and good prognosis. On the other hand, CLFLG-AS represents the heart-failure with reduced ejection fraction (HFrEF) form of AS and was associated with the worst prognosis, whereas PLFLG-AS represents the heart-failure with preserved ejection fraction (HFpEF) form of AS with intermediary prognosis. Both groups showed early hemodynamic reverse response after TAVR. PMID: 31566569 [PubMed - as supplied by publisher]

ConclusionsExercise RHC is feasible and safe in this population. Peak pulmonary artery oxygen saturation might identify patients with increased risk of serious adverse events.ResumenIntroducción y objetivosLa estenosis aórtica degenerativa es la valvulopatía más frecuente. Aún no está claro cómo identificar a los pacientes asintomáticos con fracción de eyección del ventrículo izquierdo normal y alta probabilidad de eventos que por ello pudieran beneficiarse de una intervención valvular precoz. En este estudio se describe un protocolo de hem...

CONCLUSION: Our early data clearly shows that in our country, TAVR is a good alternative for symptomatic severe AS for high surgical risk cases. Large-scale multicenter studies are required to study the real impact of TAVR in the Indian scenario. During initial years of implementation of a nationwide TAVR program, it may be prudent to focus on creating TAVR Centers of Excellence by developing an ideal hub and spokes model.

AbstractObjectivesTo assess the in ‐hospital outcomes of transcatheter aortic valve replacement (TAVR) vs. surgical aortic valve replacement (SAVR) in non‐teaching hospitals.BackgroundTAVR has become widely available in the United States. However, the comparative outcomes of TAVR vs. SAVR in non ‐teaching hospitals are largely under explored.MethodsWe queried the Nationwide Inpatient Sample database from 2011 to September 2015 to identify those who were 50 years or above and underwent either trans ‐arterial TAVR or SAVR at non‐teaching hospital. In‐hospital clinical outcomes were compared with odds ratio (OR) i...

Abstract During the late 1950s and most of the 1960s, Dr John Ross and I led the busy clinical cardiology program then existing at the Clinical Center of the National Institutes of Health. During this period, the assessment and surgical treatment of severe aortic stenosis (AS) in adults, predominantly rheumatic in origin, were both undergoing rapid changes. In the 1950s, before open heart surgery and left-sided heart catheterization were available, after thoracotomy dilators were inserted through a ventriculotomy, and severely obstructed aortic valves were "blindly" opened.1 The selection of patients for...

Abstract BackgroundEvolut‐R 34 mm (received CE mark in January 2017) and Sapien‐3 29 mm are the only options for transcatheter aortic valve replacement (TAVR) in patients with annulus ≥26 mm. We compared the short‐term outcomes of these valves in these patients. MethodsData was collected prospectively from consecutive patients with severe aortic stenosis and annulus diameter larger than 26 mm treated by femoral approach TAVR. ResultsBetween February 1, 2014 to August 19, 2017 Sapien‐3 29 mm was implanted in 55 and Evolut‐R 34 mm in 37 consecutive patients. Device success rate was 98.2% and 97.3% (P =&th...
