BACKGROUND: In high-risk patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR) diabetes mellitus (DM) is a common comorbidity. It is known to increase the risk of arteriosclerosis and adversely affect morbidity, mortality for all types of cardiovascular disease, and post-procedural outcome after percutaneous and surgical procedures. Moreover, DM is known to facilitate the genesis of renal failure (RF). Pre-existing RF seems to increase the rate of acute kidney injury (AKI), which is a powerful short- and midterm predictor of mortality in patients undergoing TAVR...

We aimed to evaluate the safety and feasibility of PCI (percutaneous coronary intervention) for coronary artery disease (CAD) in patients undergoing transcatheter aortic valve replacement (TAVR) by performing a meta-analysis. A systemic search of the database was performed. Studies were included comparing TAVR versus TAVR with PCI for significant CAD in patients undergoing TAVR for severe aortic stenosis. The primary outcome was 30 day mortality and secondary outcomes were myocardial infarction, stroke, life threatening bleeding, major access site vascular complications and renal failure...

BACKGROUND: In the evolving field of transcatheter aortic valve replacements a new generation of valves have been introduced to clinical practice. With the complexity of the TAVR procedure and the unique aspects of each TAVR device, there is a perceived risk that changing or adding a new valve in a department could lead to a worse outcome for patients, especially during the learning phase. The objective was to study the safety aspect of introducing a second generation repositionable transcatheter valve (Boston Scientific Lotus valve besides Edwards Sapien valve) in a department...

AIMS: Quantitative mitral regurgitation (MR) grading remains challenging. This study evaluated the concept of integrating echocardiography and computed tomography for grading MR severity. Specifically, an integrated parameter was developed that combines the true cross-sectional mitral regurgitant orifice area (ROA) assessed with multi-detector row computed tomography (MDCT) with flow data from echocardiography. METHODS AND RESULTS: Systolic MDCT data of 73 patients, referred for transcatheter aortic valve implantation (TAVI) who also had MR, were evaluated...

We report a case of emergency transcatheter aortic valve replacement (TAVR) in a 65-year-old patient presenting with decompensated severe aortic stenosis. Transesophageal echocardiography (TEE) was used effectively to obtain measurements of the aortic annulus and for intra-procedural guidance. At baseline, we detected a left atrial appendage thrombus and a localized aortic root dissection after balloon valvuloplasty. The case highlights the important role that TEE may play during TAVR procedures.

Transcatheter aortic valve replacement (TAVR) emerged as a promising alternative to surgical aortic valve replacement (SAVR) in extreme-aged patients with severe aortic stenosis (AS). Data on the outcomes of TAVR or SAVR in nonagenarians are limited. The Nationwide Inpatient Sample was used to identify patients aged 90 years or older who underwent TAVR or SAVR from 2004 to 2013. In-hospital morbidity and mortality were assessed. From 2004 to 2013, 9,066 (national estimate) nonagenarians underwent aortic valve replacement...

The use of transcatheter aortic valve replacement (TAVR) for high-risk patients with aortic stenosis has rapidly increased during the past years. Accordingly, more and more patients are referred for a follow-up echocardiographic study after TAVR. However, the echocardiographic evaluation of patients who underwent TAVR places specific demands on echocardiographers. Furthermore, TAVR may be associated with new types of complications, which are frequently unrecognized or underestimated due to lack of familiarity with the normal and pathological appearance of TAVR...

We assessed the effect of a transcatheter aortic valve replacement (TAVR) program and Heart Team concept on our approach to severe isolated symptomatic aortic stenosis (AS) with regard to surgical practice, patient selection, perioperative outcomes, 1-year survival, and AVR volume. TAVR program began in August 2011. Patients having isolated surgical AVR between January 2008 and August 2011, when the program began (n = 282, 42 months), were compared with those after the program began until February 2015 (n = 344, surgical AVR and n = 126, TAVR, 42 months)...

The objective of this study is based on the phase of care mortality analysis (POCMA), an effective tool to evaluate the root cause of in-hospital mortality in cardiac surgery patients. POCMA has not been used to compare operative mortalities among transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) populations, and may provide insight that could affect patient safety initiatives and improve outcomes in aortic valve surgery. We included patients who underwent TAVR or isolated SAVR between 2011 and March 31, 2015 and did not survive the index hospitalization...

Despite the widespread use of transcatheter aortic valve replacement (TAVR) for moderate and high-risk patients with severe aortic stenosis, it is utilized less frequently in patients with bicuspid aortic valves (BAV). Orthotopic heart transplant (OHT) donors tend to be younger and may have undiagnosed BAV. We present a case of successful TAVR in a patient with BAV thirteen years after OHT.

BACKGROUND: Balloon pre-dilatation before transcatheter aortic valve replacement (TAVR) is performed at the discretion of the treating physician. Clinical data assessing the implications of this step on procedural outcomes are limited. METHODS: We conducted a retrospective analysis of 1164 consecutive TAVR patients in the Israeli multicenter TAVR registry (Sheba, Rabin, and Tel Aviv Medical Centers) between the years 2008 and 2014. Patients were divided to those who underwent balloon pre-dilation (n=1026) versus those who did not (n=138)...

AIMS: Calcified aortic stenosis (AS) and mitral annular calcification (MAC) have certain similar etiology and pathophysiological mechanisms. MAC is frequently encountered in pre-procedural computed tomography (CT) imaging of patients that undergo transcatheter aortic valve replacement (TAVR), but its prognostic implications for these patients have not been thoroughly investigated. This study sought to evaluate the prevalence of MAC among patients with severe AS and to assess the clinical implications of MAC on these patients during and following TAVR...
