Percutaneous therapies for congenital heart disease have been evolving rapidly despite limited investment from industry. The Melody transcatheter pulmonary valve (Medtronic, Inc, Minneapolis, MN USA) replacement therapy represents an important advancement in this arena. It has been approved in the United States for use in the pulmonary position, on a Humanitarian Device Exemption status. Off-label use of the Melody transcatheter pulmonary valve has extended to the mitral, pulmonary, and aortic valves, especially in previously implanted valves with prosthetic valve degeneration...

OBJECTIVES: Patients with symptomatic severe aortic stenosis and severe mitral regurgitation or severe tricuspid regurgitation were excluded from the major transcatheter aortic valve replacement trials. We studied these 2 subgroups in patients at extreme risk for surgery in the prospective, nonrandomized, single-arm CoreValve US Expanded Use Study. METHODS: The primary end point was all-cause mortality or major stroke at 1 year. A favorable medical benefit was defined as a Kansas City Cardiomyopathy Questionnaire overall summary score greater than 45 at 6 months and greater than 60 at 1 year and with a less than 10-point decrease from baseline...

Joseph L Blackshear
Gastrointestinal bleeding with severe aortic stenosis was originally described in the 1950s by Heyde, although for years, the association was debated. Further discovery of mechanisms and the ubiquity and severity of acquired von Willebrand syndrome in the left ventricular assist device therapy have removed any doubts. At this time, gastrointestinal bleeding from intestinal angiodysplasia in patients with turbulence-related proteolysis of the highest molecular weight multimers of von Willebrand factor is now known to occur in patients with aortic stenosis, and also subaortic obstruction and associated mitral insufficiency in hypertrophic cardiomyopathy, isolated mitral and aortic insufficiency, endocarditis, and in patients with prosthetic valve dysfunction, either from stenosis or insufficiency...

RATIONALE: Iatrogenic atrial septal defects caused by cardiac surgery are rare complications that are traditionally repaired through reoperations; unfortunately, reoperations are accompanied by high risk and trauma. PATIENT CONCERNS: Herein, we report a rare case of a huge atrial septal defect after mitral and aortic mechanical valve replacement. DIAGNOSES: Transesophageal echocardiography revealed a 20 × 33 mm atrial septal defect with a mainly left-to-right shunt and bidirectional shunt...

REVIEW
Minoru Tabata
The left ventricular apex has excellent accessibility to the aortic valve, mitral valve, left ventricular outflow tract and thoracic aorta. Although the number of transapical approach in transcatheter aortic valve replacement has been decreasing in recent years, it is still a useful option for patients with very poor peripheral vascular access. The apex has been chosen as a primary access site for many devices of transcatheter mitral valve repair/replacement and mitral valve-in-valve procedures. Additionally, the transapical approach has been used for other transcatheter cardiovascular interventions such as paravalvular leak repair after mitral or aortic valve replacement, pseudoaneurysm repair of the left ventricular outflow tract, and thoracic endovascular aortic repair...

OBJECTIVES: We aimed to evaluate the incidence and midterm clinical outcomes of left ventricular obstruction (LVO) after transcatheter aortic valve implantation (TAVI). BACKGROUNDS: LVO is occasionally unmasked following valve replacement for severe aortic stenosis. However, little is known about the prevalence and effects of LVO after TAVI. METHODS: A total of 158 patients who underwent TAVI in our center between October 2013 and November 2015 received echocardiographic evaluations at baseline; before hospital discharge; and at 3, 6, and 12 months after TAVI...

INTRODUCTION: Three-dimensional (3D) prototyping is a novel technology which can be used to plan and guide complex procedures such as transcatheter mitral valve replacement (TMVR). METHODS: Eight patients with severe mitral annular calcification (MAC) underwent TMVR. 3D digital models with digital balloon expandable valves were created from pre-procedure CT scans using dedicated software. Five models were printed. These models were used to assess prosthesis sizing, anchoring, expansion, paravalvular gaps, left ventricular outflow tract (LVOT) obstruction, and other potential procedure pitfalls...

There is considerable interest in transcatheter prosthetic valve treatment for mitral valve disease in high-risk individuals. Although the presence of mitral annular calcium (MAC) may provide an anchoring zone for such devices, results to date have been modest with reported technical failure rates approaching 30% in specialist centers. This in part relates to the risk of left ventricular outflow tract obstruction and device dislodgment but also to the lack of specific imaging guidelines to plan for such procedures...

Objectives: Transcatheter aortic valve implantation (TAVI) and transcatheter mitral valve repair (TMVR) are increasingly used for managing patients with valvular heart disease to whom surgery presents a high-risk. As these are costly procedures, a systematic review of studies concerned with their economic assessment was undertaken. Methods: The search was performed in PubMed and the Cochrane Library and followed recommended methodological steps. Studies were screened and their data were retrieved and were synthesized using a narrative approach...

Transcatheter heart valve replacement technology was introduced as alternative to surgery for the growing high-risk profile population. Developed first, aortic valve replacement (TAVR) became a standard of care for patients with severe aortic stenosis at high operative risk, with a potential future use also for low-risk subjects. In the last decade, a multitude of transcatheter mitral valve replacement (TMVR) devices have been developed for the treatment of severe mitral regurgitation, with encouraging results coming from first-in-man and feasibility studies...

BACKGROUND: Tricuspid valve regurgitation (TR) is often not taken into consideration in the prognostication of patients undergoing transcatheter aortic valve replacement (TAVR). Accordingly, its impact on such patients remains relatively poorly defined. The study aim was to explore the effect of TR and parameters of right ventricular (RV) function on outcomes in patients undergoing TAVR. METHODS: Baseline demographic and echocardiographic data were collected for 460 consecutive patients undergoing TAVR at the authors' institution between 2012 and 2015...

BACKGROUND: Significant mitral regurgitation in patients undergoing transcatheter aortic valve replacement (TAVR) is associated with increased mortality. The aim of this study is to determine if surgical correction of both aortic and mitral valves in high risk patients with concomitant valvular disease would offer patients better outcomes than TAVR alone. METHODS: A retrospective analysis of 43 high-risk patients who underwent concomitant surgical aortic valve replacement and mitral valve surgery from 2008 to 2012 was performed...

Extensive mitral annulus calcifications are considered a contraindication for valve surgery. We describe the case of a 76-year-old female with severe mitral and aortic stenosis associated with extensive calcifications of the heart. The patient underwent an open mitroaortic valve replacement using transcatheter aortic valve implantation with an Edwards SAPIEN XT valve (Edwards Lifesciences Corp., Irvine, CA, USA) in the mitral position. The aortic valve was replaced using a stentless valve prosthesis (LivaNova SOLO; LivaNova PLC, London, UK)...

OBJECTIVE: Demonstrate proof-of-concept validation of a computed tomography (CT) computer-aided design prediction modeling tool to identify patients at risk for left ventricular outflow tract (LVOT) obstruction in transcatheter mitral valve replacement (TMVR). BACKGROUND: LVOT obstruction is a significant and even fatal consequence of TMVR. METHODS: From August 2013 to August 2017, 38 patients in 5 centers underwent TMVR with compassionate use of balloon-expandable valves for severe mitral valve dysfunction because of degenerative surgical mitral ring, bioprosthesis, or severe native mitral stenosis from to severe mitral annular calcification...
