BACKGROUND Transient left ventricular apical ballooning syndrome (TLVABS) is an acute cardiac syndrome mimicking ST-segment elevation myocardial infarction characterized by transient wall-motion abnormalities involving apical and mid-portions of the left ventricle in the absence of significant obstructive coronary disease. METHODS Searching the MEDLINE(More)
OBJECTIVES The aim of this study was to assess the role of transcatheter aortic valve implantation (TAVI) compared with medical treatment (MT) and surgical aortic valve replacement (SAVR) in patients with severe aortic stenosis (AS) at increased surgical risk. BACKGROUND Elderly patients with comorbidities are at considerable risk for SAVR. METHODS(More)
Atrioventricular (AV) conduction impairment is well described after surgical aortic valve replacement, but little is known in patients undergoing transcatheter aortic valve implantation (TAVI). We assessed AV conduction and need for a permanent pacemaker in patients undergoing TAVI with the Medtronic CoreValve Revalving System (MCRS) or the Edwards Sapien(More)
BACKGROUND Transcatheter aortic valve implantation (TAVI) is a treatment option for high-risk patients with severe aortic stenosis. Previous reports focused on a single device or access site, whereas little is known of the combined use of different devices and access sites as selected by the heart team. The purpose of this study is to investigate clinical(More)
AIMS Patients with ST-segment elevation myocardial infarction (STEMI) feature thrombus-rich lesions with large necrotic core, which are usually associated with delayed arterial healing and impaired stent-related outcomes. The use of bioresorbable vascular scaffolds (Absorb) has the potential to overcome these limitations owing to restoration of native(More)
BACKGROUND Early generation drug-eluting stents (DESs) reduce restenosis and repeat revascularization procedures. However, the long-term safety and efficacy of early generation DES according to diabetic status are poorly established. METHODS A total of 1,012 patients were randomly assigned to treatment with sirolimus-eluting (n = 503) or(More)
AIMS Our aim was to evaluate the invasive haemodynamic indices of high-risk symptomatic patients presenting with 'paradoxical' low-flow, low-gradient, severe aortic stenosis (AS) (PLF-LG) and low-flow, low-gradient severe AS (LEF-LG) and to compare clinical outcomes following transcatheter aortic valve implantation (TAVI) among these challenging AS(More)
A 91-year-old female patient presented with worsening exertional dyspnea 1 month after transfemoral aortic valve implantation using an Edwards Sapien valve. She was found to have a paraprosthetic sinus of Valsalva rupture with a left-to-right shunt into the right ventricular cavity. The patient underwent coil closure of the defect with successful shunt(More)
AIMS Transcatheter aortic valve implantation (TAVI) has emerged as a treatment alternative to surgical aortic valve replacement in elderly high-risk patients with symptomatic severe aortic stenosis. In this patient population, rapid improvement or restoration of quality of life (QoL) is at least as important as improved clinical outcomes. The purpose of the(More)
The aim of this study was to identify predictors of 30-day and midterm mortality after transcatheter aortic valve implantation (TAVI) by means of a systemic review. TAVI was demonstrated to be safe and efficacious in patients with severe aortic stenosis. An accurate estimation of procedural risk of these patients represents an actual challenge. The PubMed(More)
