Long-term results and durability of the CoreValve transcatheter aortic bioprosthesis: outcomes beyond five years.

Aims: The aim of this study was to determine the long-term outcomes of high-risk patients who underwent transcatheter aortic valve implantation (TAVI) with the third-generation CoreValve device, according to the 2017 EAPCI/ESC/EACTS definition of valve durability.

Methods And Results: Between 2007 and 2013, 278 consecutive patients were enrolled in our prospective single-centre CoreValve registry (mean age 82±6 years, mean STS score 6.4±5.

A narrative overview: Have clinical trials of PCI vs medical therapy addressed the right question?

Background: In RCTs about revascularization, the terms "coronary artery disease" and "ischemic heart disease" are sometimes used interchangeably. This can create confusion concerning inclusion and exclusion criteria, which may lead to uncertain results.

Objective: Our purpose is to investigate whether the study populations in randomized controlled trials (RCTs) which compared percutaneous coronary revascularization to medical therapy for stable ischemic heart disease specifically enrolled patients with demonstrable ischemia, and how many patients were included in trials with evidence of coronary atherosclerosis but without evidence of ischemia.

Hypotestosteronemia is frequent in ST-elevation myocardial infarction patients and is associated with coronary microvascular obstruction.

Background: Gonadal function is thought to be involved in existing atherosclerotic plaques stabilization and might affect reperfusion after primary percutaneous coronary intervention (pPCI). We aimed to compare the prevalence of hypotestosteromenia between ST-elevation myocardial infarction (STEMI) and stable angina (SA) patients and between patients with and without microvascular obstruction (MVO).

Design: Cross-sectional observational study.

Association between inflammatory biomarkers and in-stent restenosis tissue features: an Optical Coherence Tomography Study.

Aims: Inflammatory reaction after stent implantation is associated with in-stent restenosis (ISR). We assessed the association of optical coherence tomography (OCT) features of neointima with systemic levels of high-sensitivity C-reactive protein (hs-CRP) and eosinophil cationic protein (ECP) measured at the time of ISR detection.

Methods And Results: Patients presenting with symptomatic angiographically documented ISR (diameter stenosis ≥ 50% by visual estimation) were included.

Case-control registry of excimer laser coronary angioplasty versus distal protection devices in patients with acute coronary syndromes due to saphenous vein graft disease.

Laser atherectomy might decrease procedural complications during percutaneous coronary intervention (PCI) of degenerated saphenous vein grafts (SVGs) in case of unstable or thrombotic lesions because of its ability to debulk and vaporize thrombus. We aimed at prospectively evaluating the safety and efficacy of excimer laser coronary angioplasty (ELCA) as a primary treatment strategy in consecutively unstable patients undergoing PCI of degenerated SVG lesions. Seventy-one consecutive patients with non-ST elevation acute coronary syndrome (mean age 69 ± 10 years, 66 men [89%]) undergoing PCI of degenerated SVG were enrolled in a prospective case-control registry, using 2 different distal protection devices (DPDs; FilterWire EZ [Boston Scientific, Natick, Massachusetts; n = 24] and SpiderRX [Ev3, Plymouth, Minnesota; n = 23]) or ELCA (n = 24).

Serum levels of γ-glutamyltransferase and progression of coronary atherosclerosis.

Background: Progression of coronary atherosclerosis (ATS) has clinical implications. Serum levels of γ-glutamyltransferase (GGT), a marker of oxidative stress, predict the risk of cardiovascular events. However, the role of GGT levels in the progression of coronary ATS has never been established.
