BACKGROUND Outcome after atrial fibrillation (AF) recurrence after ablation remains poorly characterized. OBJECTIVE To determine whether the time to recurrence of AF after catheter ablation impacts outcome. METHODS Four hundred thirty-nine consecutive patients with AF after catheter ablation were categorized as early recurrence (E) (3-6 months after(More)
BACKGROUND Frequent ventricular premature depolarizations (VPDs) can cause cardiomyopathy (CMP). The mechanisms underlying its development remain unclear, with VPD burden being only a weak predictor of risk. OBJECTIVE To determine whether VPD QRS duration at the time of initial presentation could predict risk for the subsequent development of CMP in(More)
INTRODUCTION Patients with persistent and longstanding persistent atrial fibrillation (AF) have a higher recurrence rate after antral pulmonary vein isolation (PVI). We sought to determine the clinical, invasive, and noninvasive diastolic function parameters that are associated with AF recurrence after ablation in patients with persistent and longstanding(More)
INTRODUCTION Diverse atrial tachycardias (ATs) can develop after open heart surgery. The aim of our study was to examine the determinants of the mechanism of postoperative AT. METHODS AND RESULTS One hundred patients with AT occurring at least 3 months after open heart surgery were studied. Patients were grouped according to the atrial incision applied at(More)
Atrial tachycardias are common after open heart surgery. Most commonly these are macro-reentrant including cavotricuspid isthmus dependent atrial flutter, incisional right atrial flutter and left atrial flutter. Focal atrial tachycardias occur less frequently. The specific type of atrial tachycardia highly depends on the type of surgical incision. Catheter(More)
Clinical echocardiographic assessment of left ventricular (LV) systolic and diastolic function is routinely performed following orthotopic heart transplantation (OHT). The purpose of this study was to determine whether echocardiographic indices of LV diastolic function correlate with pulmonary capillary wedge pressure (PCWP) in the transplanted heart.(More)
INTRODUCTION Transposition of the great arteries is one of the most common cyanotic congenital heart diseases. AIM The present study aimed to examine and compare long-term survival, functional grading, arrhytmologic and quality of life control in patients with transposition of the great arteries following Senning- and Mustard-operations. METHODS The(More)
