BACKGROUND: There are limited data regarding the influence of liver dysfunction on outcomes of transcatheter aortic valve implantation (TAVI). Model for End-stage Liver Disease eXcluding International normalized ratio (MELD-XI) score, which was originally developed for patients with cirrhosis awaiting liver transplantation, has been reported as a predictor of heart disease. The aim of this study was to investigate the prognostic value of MELD-XI score for patients undergoing TAVI. METHODS: Data from the prospectively maintained Optimized transCathEter vAlvular iNtervention (OCEAN-TAVI) multicenter registry were collected in 749 patients who underwent TAVI between October 2013 and August 2015...

BACKGROUND: Several studies have found that standard risk scores inaccurately reflect risk in TAVI cohorts. The assessment of mortality risk upon post-interventional ICU admission is important to optimizing clinical management. This study sought to determine outcomes and factors affecting mortality in patients admitted to the intensive care unit (ICU) after transcatheter aortic valve implantation (TAVI), and to analyze and compare the predictive values of SAPS II and EuroSCORE. METHODS AND FINDINGS: 214 consecutive patients treated with transfemoral TAVI (2006-2012) admitted to the ICU in an academic tertiary-care university hospital, were included in this retrospective data analysis...

Paravalvular leak (PVL) is a serious complication after surgical valve replacement or after transcatheter aortic valve replacement. Approximately 1-5% of PVLs can lead to serious clinical consequences, including congestive heart failure and/or haemolytic anaemia. For years, surgical re-intervention has been considered the treatment of choice for symptomatic patients with PVLs. However, surgical re-intervention is associated with a high risk of morbidity and mortality. Transcatheter PVL (TPVL) closure is a less invasive alternative to surgical re-intervention...

Aortic stenosis is one the most frequent valvular diseases in developed countries, and its impact on public healthcare resources and assistance is increasing. A substantial proportion of elderly patients with severe aortic stenosis is frequently not eligible for surgery because of advanced age, frailty and multiple comorbidities. Transcatheter aortic valve implantation (TAVI) enables the treatment of very elderly patients at high or prohibitive surgical risk considered ineligible for surgery and with an acceptable life expectancy...

Aortic stenosis is the most frequent and mitral stenosis is the least frequent native single-sided valve disease in Europe. Patients with the combination of severe symptomatic degenerative aortic and mitral stenosis are very rare. Guidelines for the treatment of heart valve diseases are clear for single-valve situations. However, there is no common agreement or recommendation for the best treatment strategy in patients with multiple valve disease and severe concomitant comorbidities. A 76-year-old female patient with the combination of severe degenerative symptomatic aortic and mitral stenosis and several comorbidities including severe obesity, who was found unsuitable surgical candidate by the heart team and unsuitable for two-time general anesthesia in the case of two-step single-valve percutaneous approach by anesthesiologists, underwent successful percutaneous dual-valve single-intervention (transcatheter aortic valve implantation and percutaneous mitral balloon commissurotomy)...

As transcatheter aortic valve replacement (TAVR) has become routine, device manufacturers and investigational cardiologists have set their sights on the mitral valve. Although transcatheter mitral valve replacement (TMVR) poses several technical challenges, they appear to be surmountable, and work is proceeding. Here we review the various devices being developed and preliminary results of trials in humans.

Transcatheter mitral valve therapy requires an in-depth understanding of the mitral valve apparatus (annulus, leaflets, chordae tendinae, and papillary muscles) and the impact of various disease states. Adjacent structures (left atrium, left ventricular outflow tract, aortic valve, coronary sinus, and circumflex artery) must also be respected. This article reviews the anatomy and function of the normal and diseased mitral valve apparatus and the implications for catheter-based intervention.

In daily practice, the iatrogenic complication hydrophilic polymer embolization (HPE) is under-recognized. An 86-year-old male experienced a distal foot embolization after transcatheter aortic valve replacement. Rashes appeared only in the access side foot just after the procedure. Gradual worsening of the rashes was first thought to be cholesterol crystal embolization (CCE), but a pathological examination revealed HPE. The clinical course following the diagnosis was uneventful without notable treatment. We experienced a rare but important alternative differential diagnosis of CCE after catheter intervention...

OBJECTIVES: A thorough understanding of mitral and aortic valve motion dynamics is essential in mastering the skills necessary for performing successful valve intervention (open or transcatheter repair or replacement). We describe a reproducible and versatile beating-heart mitral and aortic valve assessment and valve intervention training model in human cadavers. METHODS: The model is constructed by bilateral ligation of the pulmonary veins, ligation of the supra-aortic arteries, creating a shunt between the descending thoracic aorta and the left atrial appendage with a vascular prosthesis, anastomizing a vascular prosthesis to the apex and positioning an intra-aortic balloon pump (IABP) in the vascular prosthesis, cross-clamping the descending thoracic aorta, and finally placing a fluid line in the shunt prosthesis...

Transcatheter aortic valve implantation (TAVI) has become a well-established intervention with reproducible and excellent early and mid-term outcomes. A minimalist approach to TAVI is already the standard of care in many experienced centers. In this report, we share our experience and opinions on how we can further simplify the TAVI procedure in hope to establish the best possible outcomes.

Aortic valve replacement is no longer an operation that is approached solely through a median sternotomy. Recent advances in the fields of transcatheter valves have expanded the proportion of patients eligible for intervention. Comparisons between transcatheter valves and conventional surgery have shown non-inferiority of transcatheter valve implants in patients with a high or intermediate pre-operative predictive risk. With advances in our understanding of sutureless valves and their applicability to minimally invasive surgery, the invasiveness and trauma of surgery can be reduced with potential improvements in outcome...
