Hypoplastic left heart syndrome (HLHS) represents a variety of cardiac malformations that may result from errors in the early stages of cardiac development. HLHS includes a wide spectrum of cardiac malformations including hypoplasia of the left ventricle, ascending aorta, hypoplasia, or atresia of the aortic and mitral valves. Over the recent years, the improved resolution of advanced equipment with awareness and increased performance of second-trimester ultrasound examinations for the assessment of fetal anomalies have helped in understanding the spectrum and have expanded our knowledge of HLHS...

Bicuspid aortic valve (BAV) stenosis has been considered a contraindication to transcatheter aortic valve implantation (TAVI). The aim of this study is to compare the efficacy and safety of TAVI in patients with BAV with those with tricuspid aortic valve (TAV) using balloon-expandable and self-expanding transcatheter heart valves. This retrospective study included 823 consecutive patients with severe, symptomatic aortic valve stenosis undergoing TAVI in 2 institutions, Baylor Heart and Vascular Hospital (Dallas, TX) and The Heart Hospital Baylor Plano (Plano, TX), from January 2012 to February 2016...

AIMS: Safety and efficacy of single vs. dual antiplatelet therapy (DAPT) in patients undergoing TAVI remain to be addressed. METHODS AND RESULTS: All consecutive patients enrolled in the ITER registry were included. Patients undergoing TAVI discharged with aspirin alone were compared to those assuming DAPT before and after selection with propensity score with matching. Subgroup analysis was performed for those on OAT. Prosthetic heart valve dysfunction at follow-up was the primary end point whereas all cause death, cardiovascular death, bleedings, vascular complications and cerebrovascular accidents were the secondary ones...

Cardiac computed tomography (CT) provides additional information with ultrasound in the transcatheter heart valve (THV) size selection. However, the influence of these incremental data on outcomes has not been evaluated in a randomized study. A single-center prospective, randomized, and open study was performed. Patients referred for transfemoral transcatheter aortic valve implantation with a balloon-expandable endoprothesis were included. THV size selection was performed using either transthoracic and transesophageal echocardiography data (control group) or ultrasound and CT results (CT group)...

The first case of a novel JenaValve design using the transfemoral approach in a 78 year old female patient with pure aortic regurgitation is described. The implantation was successfully performed with excellent haemodynamics and good clinical outcome at 6 months follow up. The technology is especially appealing in non-calcified anatomies due to the clipping mechanism that has been previously utilized in the transapical design.

Mitral regurgitation is one of the more common forms of valvular heart disease. Given the expansion of therapies for structural heart disease, new therapies for mitral regurgitation are emerging. An accurate description and classification of mitral disease is important to understand pathology and provide recommendations for therapy. Areas covered: In the modern evaluation of mitral regurgitation, 3-dimensional echocardiography (3DE) and cardiac magnetic resonance imaging (CMR) play important roles which overcome the prior limitations of 2-dimensional echocardiography...

Prosthetic valve endocarditis is a very grave and often terminal disease. Surgical valve replacement remains the cornerstone treatment for this disease. However, it is often contraindicated. Herein, we describe the implantation under direct visualization of a self-expandable transcatheter heart valve in a prohibitive surgical risk patient with homograft aortic valve endocarditis.

BACKGROUND: Balloon predilatation of the aortic valve has been regarded as an essential step during the transcatheter aortic valve implantation (TAVI) procedure. However, recent evidence has suggested that aortic valvuloplasty may cause complications and that high success rates may be obtained without prior dilatation of the valve. We hypothesize that TAVI performed without predilatation of the aortic valve and using new-generation balloon-expandable transcatheter heart valves is associated with a better net clinical benefit than TAVI performed with predilatation...
