Information on the cardiac manifestations of coronavirus disease 2019 (COVID-19) is scarce. We performed a systematic and comprehensive echocardiographic evaluation consecutive patients hospitalized with COVID-19 infection.
Data on the age at first arrhythmic event (AE) in Brugada syndrome are from limited patient cohorts. The aim of this study is 2-fold: (1) to define AE a large cohort patients with syndrome, and (2) assess influence mode documentation, sex, ethnicity AE.A survey 23 centers 10 Western 4 Asian countries gathered data 678 (91.3% men) documented time aborted cardiac arrest (group A, n=426) or after prophylactic implantable cardioverter-defibrillator implantation B, n=252). vast majority (94.2%)...
Paravalvular regurgitation (PVR) after transcatheter aortic valve implantation (TAVI) is associated with increased morbidity and mortality. The effect of interventions to treat PVR the index TAVI was investigated.A registry consecutive patients who underwent intervention for ≥ moderate at 22 centers. principal outcomes were residual (AR) mortality 1 year treatment. A total 201 identified: 87 (43%) redo-TAVI, 79 (39%) plug closure, 35 (18%) balloon valvuloplasty. Median...
Background— The basic defect in long-QT syndrome type III (LQT3) is an excessive inflow of sodium current during phase 3 the action potential caused by mutations SCN5A gene. Most channel blockers reduce early (peak) and late components ( I Na NaL ), but ranolazine preferentially reduces . We, therefore, evaluated effects LQT3 D1790G mutation Methods Results— We performed experimental study TSA201 cells expressing mutation. then a long-term clinical evaluation patients carrying In study, was...
Background: Polymorphic ventricular tachycardia (VT) without QT prolongation is well described in patients structural heart disease (mainly idiopathic fibrillation and Brugada syndrome) with acute ST-elevation myocardial infarction. Methods: Retrospective study of polymorphic VT related to coronary artery disease, but evidence ischemia. Results: The authors identified 43 whom developed within days an otherwise uncomplicated infarction or revascularization procedure. events were invariably...
Background The scope of pericardial involvement in COVID-19 infection is unknown. We aimed to evaluate the prevalence, associates, and clinical impact hospitalized patients with COVID-19. Methods Results Consecutive underwent echocardiographic examination, irrespective indication, within 48 hours as part a prospective predefined protocol. Protocol included symptoms signs suggestive pericarditis, calculation modified early warning score, ECG assessment for effusion, left right ventricular...
Abstract Aims Indications for surgery in patients with degenerative mitral regurgitation (DMR) are increasingly liberal all clinical guidelines but the role of secondary outcome determinants (left atrial volume index ≥60 mL/m2, fibrillation, pulmonary artery systolic pressure ≥50 mmHg and moderate to severe tricuspid regurgitation) their impact on post-operative remain disputed. Whether these markers just reflective DMR severity or intrinsically affect survival after is uncertain may have...
Abstract Aims Asses the added value of quantitative evaluation tricuspid regurgitation (TR), proper cut-off for severe TR and ‘torrential TR’ based on outcome data. The TR, values associated with increased mortality are unknown. Methods results In patients all-cause assessed both qualitatively quantitatively by proximal iso-velocity surface area method, long-term 1-year analysis was conducted. Thresholds excess were using spline curves, receiver-operating characteristic minimum P-value...
Abstract Aims Distinctive types of polymorphic ventricular tachycardia (VT) respond differently to different forms therapy. We therefore performed the present study define electrocardiographic characteristics VT. Methods and results studied 190 patients for whom onset 305 VT events was available. The group included 87 with coronary artery disease who had spontaneous triggered by short-coupled extrasystoles in absence myocardial ischaemia. This 32 a long QT interval but nevertheless their...
We aim to assess changes in routine echocardiographic and longitudinal strain parameters patients recovering from Coronavirus disease 2019 during hospitalization at 3-month follow-up.Routine comprehensive echocardiography STE of both ventricles were performed for acute coronavirus (COVID-19) infection as part a prospective pre-designed protocol compared with ∼3 months after recovery 80 patients, using similar protocol. Significantly improved right ventricle (RV) fractional area change,...
Background Information about the cardiac manifestations of Omicron variant COVID-19 is limited. We performed a systematic prospective echocardiographic evaluation consecutive patients hospitalized with infection and compared them similarly recruited were propensity matched wild-type variant. Methods Results A total 162 underwent complete within 24 hours admission propensity-matched (148 pairs). Echocardiography included left ventricular (LV) systolic diastolic, right (RV), strain,...
Abstract Aims Functional tricuspid regurgitation (FTR) associated with degenerative mitral (DMR) accentuates the severity of heart failure and is a marker poor prognosis. Little known about FTR asymptomatic DMR. Methods results The study included 1249 patients moderate or severe DMR from Mitral Regurgitation International Database‐Quantitative (MIDA‐Q) registry (mean age 64 ± 15 years, 25% female). Despite status, absent/trivial was noted in only 42%, mild 34.5%, 11%, 12.5%. Patients higher...
