Transcatheter Aortic Valve Replacement in Degenerated Perceval Bioprosthesis: Clinical and Technical Aspects in 32 Cases.

Background: Sutureless aortic bioprostheses are increasingly being used to provide shorter cross-clamp time and facilitate minimally invasive aortic valve replacement. As the use of sutureless valves has increased over the past decade, we begin to encounter their degeneration. We describe clinical outcomes and technical aspects in patients with degenerated sutureless Perceval (CorCym, Italy) aortic bioprosthesis treated with valve-in-valve transcatheter aortic valve replacement (VIV-TAVR).

Peripheral intravascular lithotripsy for transcatheter aortic valve implantation: a multicentre observational study.

Background: The presence of severe calcific atherosclerosis at the iliofemoral axis may preclude transcatheter aortic valve implantation (TAVI) by the transfemoral (TF) approach. Intravascular lithotripsy (IVL) is a novel technology that fractures intimal/medial calcium and increases vessel compliance allowing TF TAVI in selected patients with peripheral artery disease (PAD).

Aims: The aim of this study was to report on the safety and efficacy of IVL-assisted TF TAVI in an all-comers population.

3D model-guided transcatheter closure of left ventricular pseudoaneurysm: a case series.

Left ventricular pseudoaneurysm (LVPsA) is a rare complication of myocardial infarction, cardiac surgery, chest trauma, infection or transcatheter interventions. It may cause arrhythmias, mass effect, thromboembolism and life-threatening rupture. The transcatheter approach is nowadays considered a cost-effective alternative to surgery.

Clinical characteristics and outcomes of Yemeni patients with acute heart failure aged 50years or younger: Data from Gulf Acute Heart Failure Registry (Gulf CARE).

Aims: There is a shortage of data about acute heart failure (AHF) in the young, including its underlying causes, clinical presentation and outcomes. We aim to describe clinical characteristics, causes and outcomes of AHF in Yemeni patients aged 50years or younger.

Methods And Results: we evaluated Yemeni patients with AHF enrolled in Gulf CARE registry.

Endovascular treatment of acute thoracic aortic syndromes with a proximal landing zone extension strategy: procedural and follow-up results.

Purpose: To report the procedural and long-term follow-up data (mean, 43 ± 29 months; range, 12-90 months) of endovascular stent grafting (ESG) of acute thoracic aortic syndromes (ATAS) with a proximal landing zone extension strategy.

Methods: From November 1999 to May 2008, 26 patients (25 males, 1 female; mean age, 57.9 ± 17 years) with ATAS underwent ESG at our institution.

An increased platelet-leukocytes interaction at the culprit site of coronary artery occlusion in acute myocardial infarction: a pathogenic role for "no-reflow" phenomenon?

Background: Distal protection devices have been shown to reduce the incidence of "no flow" phenomenon during primary percutaneous coronary intervention (PCI). So far, it has not been well clarified which mechanism is mainly involved in distal coronary protection.

Aim: To investigate the activation state of leukocytes and platelets locally present within the blood from the site of coronary occlusion.

Detection of mtDNA with 4977 bp deletion in blood cells and atherosclerotic lesions of patients with coronary artery disease.

Recent evidence suggests that somatic mutations in nuclear and mitochondrial DNA accumulated during aging, may significantly contribute to the pathogenesis of chronic-degenerative illness such as coronary artery disease (CAD). Mitochondrial DNA with 4977 bp deletion mutation (mtDNA4977) is a common type of mtDNA alteration in humans. However, little attempt has been made to detect the presence of mtDNA4977 deletion in cells and tissues of cardiovascular patients.
