Validation of the TRI-SCORE in patients undergoing surgery for isolated tricuspid regurgitation.

Introduction: Estimation of peri-procedural risk in patients with tricuspid regurgitation (TR) undergoing isolated tricuspid valve surgery (ITVS) is of paramount importance. The TRI-SCORE is a new surgical risk scale specifically developed for this purpose, which ranged from 0 to 12 points and included eight parameters: right-sided heart failure signs, daily dose of furosemide ≥125 mg, glomerular filtration rate <30 mL/min, elevated bilirubin (with a value of 2 points), age ≥70 years, New York Heart Association Class III-IV, left ventricular ejection fraction <60% and moderate/severe right ventricular dysfunction (with a value of 1 point). The objective of the study was to evaluate the performance of the TRI-SCORE in an independent cohort of patients undergoing ITVS.

Management of Intracranial Hemorrhage During Pulsatile Long-Term Biventricular Support: When Necessity Is the Mother of Invention.

Despite improvements in device design and hemocompatibility, intracranial hemorrhage and stroke remain the most feared and devastating complications in patients under mechanical circulatory support. We present the case of a 48 year old man with advanced heart failure (INTERMACS 3) and severe biventricular dysfunction who underwent biventricular pulsatile paracorporeal device implantation (Berlin Heart Excor) as a bridge to candidacy. Although on the heart transplantation waiting list, the patient experienced an intracranial hemorrhage, which was successfully managed by switching to a less thrombogenic biventricular assist device (Levitronix Centrimag) using the Excor cannulae, thus enabling temporary withdrawal of antithrombotic therapy.

OXY-SCORE: a new perspective for left ventricular hypertrophy diagnosis.

Background: A recently developed global indicator of oxidative stress (OXY-SCORE), by combining individual plasma biomarkers of oxidative damage and antioxidant capacity, has been validated in several pathologies, but not in left ventricular hypertrophy (LVH). The aim of this study was to design and calculate a plasma oxidative stress global index for patients with LVH.

Methods: A total of 70 consecutive adult patients were recruited in our institution and assigned to one of the two study groups (control group/LVH group) by an echocardiography study.

Infective endocarditis in patients with cardiac implantable electronic devices: a nationwide study.

Aims: Patients with infective endocarditis (IE) frequently have cardiac implantable electronic devices (CIEDs). Here, we aim to define the clinical profile and prognostic factors of IE in these patients.

Methods And Results: Infective endocarditis cases were prospectively identified in the Spanish National Endocarditis Registry.

Plasma protein thiolation index (PTI) as a potential biomarker for left ventricular hypertrophy in humans.

Background: Left ventricular hypertrophy (LVH) has been associated with oxidative stress, although not with the protein thiolation index (PTI). This study explored the potential use of PTI as a biomarker of oxidative stress in patients with LVH.

Methods: We recruited 70 consecutive patients (n = 35 LVH and n = 35 non-LVH) based on an echocardiography study in our institution (left ventricular mass indexed to body surface area).
