Results of transcatheter aortic valve implantation (TAVI) for treatment of severe noncalcific isolated aortic regurgitation (AR) complicated by advanced heart failure or cardiogenic shock has been previously reported only in isolated case reports. Current self-expanding transcatheter aortic valves are designed to treat aortic valve stenosis, and have also been implanted in cases of severe AR due to degenerated bioprosthesis and in very few cases of native aortic valves. We report 13 consecutive inoperable patients with noncalcific, pure AR, and advanced heart failure treated with emergency percutaneous transfemoral implantation with self-expandable CoreValves at our institution between July 2012 and September 2017...

INTRODUCTION: Anticoagulation with warfarin affects approximately 140,000 post-cardiac surgery patients every year, yet there remains limited published data in this patient population. Dosing remains highly variable due to intrinsic risk factors that plague cardiac surgery candidates and a lack of diverse literature that can be applied to those who have undergone a cardiac surgery alternative to heart valve replacement (HVR). In the present study, our aim was to compare the warfarin requirements between HVR and non-HVR patients...

OBJECTIVES: The purpose of this study was to identify sex-specific outcomes of intermediate risk patients undergoing transcatheter aortic valve replacement with the SAPIEN 3 valve. BACKGROUND: A survival difference has been observed in women as compared with men in inoperable and high-risk patients receiving early-generation balloon-expandable valves for transcatheter aortic valve replacement (TAVR). Whether a sex-specific outcome difference persists with newer-generation valves and in lower-risk patients is unknown...

Bovine and porcine pericardia are currently used for manufacturing prosthetic heart valves: their design has become an increasingly important area of investigation in parallel with progressively expanding indications for the transcutaneous approach to heart valves replacement. Before being cut and shaped, pericardial tissues are expected to be properly characterized. Actually, the mechanical assessment of these biomaterials lacks standardized protocols. In particular, the role of preconditioning for achieving a constant mechanical response of tissue samples is still controversial...

Mitral regurgitation (MR) is the most frequent Valvular Heart Disease (VHD) and is an important cause of heart failure. MR can be caused by primary valve abnormality (Degenerative MR/Primary MR) or it can be secondary to cardiomyopathy (Functional MR/Secondary MR). Medical management alleviates symptoms but does not alter the progression of the disease. Current guidelines recommend surgery for moderate-to-severe (Grade > 3) MR in patients with symptoms or evidence of left ventricular dysfunction. Despite current practice guidelines, the majority of patients with severe MR do not undergo surgery...

PURPOSE: Transcatheter aortic valve replacement (TAVR) is an increasingly prevalent therapy in patients with severe symptomatic aortic stenosis. Conduction disturbances requiring permanent pacemaker (PPM) implantation are a known complication of TAVR. This study investigated the progression of cardiac conduction disease in the post-TAVR pacemaker population and identified predictors of post-TAVR right ventricular (RV) pacing dependence. METHODS: Prospectively collected echocardiographic, ECG, and PPM interrogation data of 262 consecutive patients who underwent TAVR with placement of a balloon-expandable valve at one institution from March 2012 to October 2016 were analyzed...

OBJECTIVE: It has been reported that balloon aortic valvuloplasty immediately before transfemoral or transapical transcatheter aortic valve implantation has mostly little to no clinical value. We aimed to provide data on the need for balloon aortic valvuloplasty in patients undergoing transaortic transcatheter aortic valve implantation. METHODS: Patients undergoing transaortic transcatheter aortic valve implantation with the Edwards SAPIEN XT (Nyon, Switzerland) or 3 transcatheter heart valve were prospectively included at 18 sites across Europe...

OBJECTIVES: Transcatheter heart valves such as the self-expandable Portico valve (St. Jude Medical) are being developed to overcome limitations of first-generation devices. Since clinical experience with this valve is still limited in a real-world setting, we investigated its use on an all-comer basis. METHODS: Between October 2015 and October 2016, a total of 100 consecutive patients assessed for transcatheter aortic valve replacement (TAVR) and found suitable for the Portico valve were included...

Procedural complications following transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) are usually reported as retrospective analyses. We report the first comparison of complications following SAVR or self-expanding TAVR from a prospectively randomized study of high-risk SAVR patients. Three hundred ninety-five TAVR and 402 SAVR patients were prospectively enrolled and randomized 1:1 to TAVR with a CoreValve bioprosthesis or a surgical bioprosthetic valve. The rates of major procedural and vascular complications occurring (periprocedurally (0-3 days) and early (4-30 days)) were compared for TAVR vs SAVR patients...

Recently, transcatheter therapy has expanded the treatment options for patients with heart valve disease. With the growing understanding of tricuspid regurgitation and its natural history, it becomes increasingly obvious that this patient population is a heterogeneous cohort presenting for treatment in different stages of a continuous disease process. It is still unclear which interventional approach will result in functional and clinical success and in which subtype of patient population. This article reviews the pathophysiologic background and current evidence for caval valve implantation and examines the potential role of this approach for the treatment of severe tricuspid regurgitation...
