Left atrial functional impairment as a predictor of atrial fibrillation: insights from cardiac CT Open
Objectives A strong association exists between left atrial (LA) structural remodeling and the development of atrial fibrillation (AF). The role of LA function in AF prediction remains unclear. We studied the relationship between LA functio…

Conduit Flow Compensates for Impaired Left Atrial Passive and Booster Functions in Advanced Diastolic Dysfunction Open
BACKGROUND: Quantification of left atrial (LA) conduit function and its contribution to left ventricular (LV) filling is challenging because it requires simultaneous measurements of both LA and LV volumes. The functional relationship betwe…

Increased rate of new-onset left bundle branch block in patients with bicuspid aortic stenosis undergoing TAVR; data from a national registry Open
Background There is a growing interest in transcutaneous aortic valve replacement (TAVR) therapy among patients with bicuspid severe aortic stenosis (BAV). Conduction disturbances remain a frequent complication of TAVR, and new-onset perma…

Characteristics of aortic root and vascular anatomy in bicuspid versus tricuspid aortic valve anatomy Open
Background Transcatheter aortic valve replacement (TAVR) is being increasingly performed in patients with bicuspid aortic valve stenosis (AS). Purpose This study sought to compare aortic root, aorta and iliofemoral artery anatomy in patien…

40 Long-term clinical outcome of functional tricuspid regurgitation Open
Background Significant functional tricuspid regurgitation (TR) has been associated with higher risk for adverse cardiovascular outcomes. Left-sided heart disease (LHD) is a potentially important confounder of this association because it is…

44 Determinants of functional tricuspid regurgitation progression Open
Background Tricuspid regurgitation has been the focus of increasing interest and research in recent years. However, few data are available with regard to risk factors associated with the evolution of TR. purpose The aimed to determine the …

Tricuspid regurgitation in acute heart failure: is there any incremental risk? Open
Patients presenting with symptomatic HF and significant TR have multiple coexisting cardiac abnormalities. TR provides no additive risk in the presence of normal or mildly elevated pulmonary pressures. However, it is associated with excess…

Time Dependence of the Effect of Right Ventricular Dysfunction on Clinical Outcomes After Myocardial Infarction: Role of Pulmonary Hypertension Open
Background The clinical importance of right ventricular ( RV ) function in acute myocardial infarction is well recognized, but the impact of concomitant pulmonary hypertension ( PH ) has not been studied. Methods and Results We studied 104…

Impact of computed tomography image and contact force technology on catheter ablation for atrial fibrillation Open
These preliminary results suggest that CT image integration and CF technology may reduce the recurrence of atrial tachyarrhythmia after catheter ablation for AF.

Acute and Mid-Term Results after Pulmonary Veins Isolation Using a Novel Circular Irrigated Multielectrode Mapping and Ablation Catheter (nMARQ) Open
Background: Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation in both paroxysmal and persistent AF. However, this procedure is still challenging and time consuming. Objective: The aim of this study was …
