Transcatheter aortic valve implantation (TAVI) is a recognized therapy for patients with symptomatic severe aortic stenosis (AS). TAVI is superior compared to medical therapy as for mortality in extreme-risk patients, is non-inferior or superior to surgery in high- risk patients and non-inferior to surgery in intermediate-risk patients. However, several limitations affect outcomes after TAVI. Adverse events related to this procedure, like vascular complications, need forpacemaker implantation, paravalvular regurgitation, can be factors limiting TAVI treatment in younger patients at lower risk, as well as uncertainties regarding valve durability...

Background Increased exercise capacity favourably influences clinical outcomes after transcatheter aortic valve implantation. In our SPORT:TAVI randomised pilot trial, eight weeks of endurance and resistance training (training group, TG) shortly after transcatheter aortic valve implantation resulted in significantly improved exercise capacity, muscular strength and quality of life compared to usual care (UC). However, the long-term clinical benefits of such an intervention are unknown. Design A randomised controlled trial...

This original clinical research study id focused on description of baseline anatomy and outcomes after transcatheter aortic valve implantation (TAVI) in patients presenting with severe aortic stenosis (AS) and bicuspid aortic valve (BAV). We compared this BAV population with a population of patients with AS and tricuspid aortic valves after a propensity score matching developed by a multivariate logistic regression according to a non-parsimonious approach. Baseline anatomical characteristics were obtained by transthoracic echocardiography (TTE) and multi-sliced computed tomography (MSCT) and compared by chi-square and t-student tests...

INTRODUCTION AND OBJECTIVES: The incidence of permanent pacemaker implantation (PPI) and new conduction abnormalities (CA) with the ACURATE neo (Symetis S.A., Eclubens, Switzerland) has not been studied in detail. We aimed to analyze their predictors, evaluating patient- and device-related factors, including implantation depth and device-to-annulus ratio (DAR). METHODS: Two analyses of a multicenter population were performed: new PPI in pacemaker-naive patients (n = 283), and PPI/new-CA in patients without prior CA or pacemaker (n = 232)...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has revolutionized the prognosis of inoperable patients with severe aortic valve stenosis. Yet, the implantation of expensive prostheses in patients with comorbidities may be questionable in an era when healthcare costs are becoming a major concern. AIM: The objective of this study was to assess whether the TAVR procedure is profitable in a high-volume French hospital. METHODS: Consecutive patients eligible for transfemoral TAVR using the SAPIEN bioprostheses (Edwards Lifesciences, Irvine, CA, USA) were included retrospectively in this single-centre study between September 2014 and December 2015...

BACKGROUND: Pulmonary arteriovenous malformations are rare vascular abnormalities that permit direct communication between the pulmonary artery and vein. During pregnancy, pulmonary arteriovenous malformation carries an increased risk of enlargement and rupture, which could lead to life-threatening hemothorax. This is the first case reporting successful thoracoscopic surgery for a pregnant woman with pulmonary arteriovenous malformation rupture-related hemothorax. CASE PRESENTATION: We present a case of a 32-year-old pregnant Asian woman (31 weeks' gestation) whose pulmonary arteriovenous malformation ruptured, leading to right-sided spontaneous tension hemothorax...

Since the first-in-man transcatheter delivery of an aortic valve prosthesis in 2002, the landscape of aortic stenosis therapeutics has shifted dramatically. While initially restricted to non-surgical cases, progressive advances in transcatheter aortic valve replacement and our understanding of its safety and efficacy have expanded its use in intermediate and possibly low surgical risk patients. In this review, we explore the past, present, and future of transcatheter aortic valve replacement.

BACKGROUND: Stroke after transcatheter aortic valve replacement (TAVR) occurs with an incidence of 4-11% and is a particularly devastating adverse event associated with the procedure. Several cerebral protection devices (CPD) have been developed to prevent cerebrovascular events during TAVR. While most studies have shown CPD to be associated with decreased number and volume of lesions on diffusion weighted magnetic resonance imaging, the clinical benefit of these devices remains uncertain...

OBJECTIVE: Arterial ketone bodies, which reflect liver function, have been investigated. However, the relationship between venous ketone bodies and hepatocellular carcinoma (HCC) is unclear. We investigated whether prognosis of patients with HCC after transcatheter arterial chemoembolization (TACE) was associated with venous blood ketone bodies. METHODS: Sixty-eight patients with HCC who underwent TACE were recruited for this study. The venous blood ketone body levels were measured 1 d before (pretreatment) and 7 d after TACE (posttreatment)...

There are few case reports in the literature of transcatheter aortic valve replacement used as emergent therapy for aortic insufficiency. We present a case in which transcatheter aortic valve replacement was implemented successfully as a salvage therapy in a hemodynamically unstable patient experiencing aortic insufficiency as a result of a torn bio-prosthetic leaflet during an unrelated abdominal operation. The successful use of this technique in a non-cardiac operating room allowed the patient to be placed on extracorporeal support and ultimately to be discharged home...

BACKGROUND: The balloon-expandable Sapien 3 (Edwards Lifesciences, Irvine, CA, USA) and the mechanically-expandable Lotus valve (Boston Scientific, Marlborough, MA, USA) are established devices for transcatheter aortic valve implantation. We sought to compare both transcatheter heart valves (THV) under consideration of the extent of THV landing zone calcification. METHODS: This retrospective analysis includes consecutive patients with severe aortic stenosis treated with Sapien 3 (S3; n=212) or Lotus (n=61) THV via transfemoral access...
