The prevalence, etiologies and clinical consequences of tricuspid regurgitation associated with severe degenerative mitral regurgitation.

Aims: The prevalence, the etiologies and the clinical features of tricuspid regurgitation (TR) in the context of concomitant degenerative mitral valve (MV) disease are poorly defined. This paper aims to assess the prevalence, determinants and clinical consequences of TR in severe degenerative mitral regurgitation (DMR).

Methods And Results: Clinical and echocardiographic characteristics were collected among patients with severe DMR.

Valve-in-valve transcatheter aortic valve implantation: The issues behind crossing a bioprosthesis.

Valve-in-valve transcatheter aortic valve implantation (ViV TAVI) is rapidly arising as a safe and effective alternative to redo-surgery in the treatment of bioprostheses deterioration. While scientific community is currently focusing its attention on the most common limitations related to this procedure, such as the risk of coronary obstruction and patient-prosthesis mismatch, data regarding the first step of a ViV TAVI, the crossing of a degenerated bioprosthesis, are still lacking. The aim of this review is to analyze the available information about bioprosthesis crossing, to show the inherent challenges encountered by interventional cardiologists during valve crossing and to describe the current strategies to perform a correct crossing.

A comprehensive and easy-to-use ECG algorithm to predict the coronary occlusion site in ST-segment elevation myocardial infarction.

Background: Several electrocardiogram (ECG) criteria have been proposed to predict the location of the culprit occlusion in specific subsets of patients presenting with ST-segment elevation myocardial infarction (STEMI). The aim of this study was to develop, through an independent validation of currently available criteria, a comprehensive and easy-to-use ECG algorithm, and to test its diagnostic performance in real-world clinical practice.

Methods: We analyzed ECG and angiographic data from 419 consecutive STEMI patients submitted to primary percutaneous coronary intervention over a one-year period, dividing the overall population into derivation (314 patients) and validation (105 patients) cohorts.

Role of cardiological specialistic evaluation in patients with chest pain presenting in the emergency department.

Aims: Aim of this study was to evaluate the impact of cardiological and echocardiographic evaluation in addition to a standard clinical and instrumental approach on diagnostic and prognostic accuracy in patients presenting in the emergency department (ED) with chest pain (CP). Acute coronary syndromes, pulmonary embolism and acute aortic syndromes (AAS) (triple-rule-out/TRO) were considered.

Methods: From 7040 patients presenting with CP from 1 January 2015 to 31 December 2017, we randomly selected a sample of 1119.

Cardiac fibrosis: emerging agents in preclinical and clinical development.

Introduction: Myocardial fibrosis is a remarkably dynamic process mediated by different molecular pathways that represent potential targets of novel therapeutic interventions. Transforming Growth Factor-beta (TGF-β), connective Tissue Growth Factor (cTGF) and Galectin-3 (Gal-3) represent the most promising targets on which research has been currently focusing.

Area Covered: This review initially discusses those drugs used in clinical practice for their anti-fibrotic properties and later examines emerging pathway-specific agents in preclinical and clinical development [phase I and II-concluded or ongoing trials].

Cardiac and sudden death after chronic total occlusion percutaneous coronary intervention: Prognostic role of the target vessel.

Background: The role of the target vessel in percutaneous revascularization of chronic total occlusion (CTO) is unclear.

Objective: We sought to assess the long-term results of percutaneous coronary intervention (PCI) for CTO lesions in each coronary artery and to investigate the impact of successful revascularization and previous myocardial infarction (MI) in the territory of the target vessel.

Methods And Results: Cohort observational study on 1,124 patients who have undergone CTO PCI attempt: 371 on left anterior descending artery (LAD), 485 right coronary artery, and 268 left circumflex.

Therapeutic sequences in patients with grade 1-2 neuroendocrine tumors (NET): an observational multicenter study from the ELIOS group.

Purpose: Many different treatments are suggested by guidelines to treat grade 1-2 (G1-G2) neuroendocrine tumors (NET). However, a precise therapeutic algorithm has not yet been established. This study aims at identifying and comparing the main therapeutic sequences in G1-G2 NET.
