Symptomatic atrial tachyarrhythmia (AT) after heart transplantation occurs in nearly 10% of orthotopic heart transplant recipients, with atrial flutter (AFL) being the most common. Case reports have described adult transplant recipients presenting with multiple ATs in the donor as well as native atria. However, there have been no reports of heart transplant recipients with biatrial anastomosis ...

The primary heart tumors have an incidence varying from 0.001% to 0.28% of all tumors, reported in necropsies series. Lipoma consists of a benign tumour corresponding to about 8% of all primary heart tumors. When present, the symptoms are related to the size and location of such tumor. We report a case of a 27-year-old man with a lipoma in the right atrium who underwent surgical treatment with ...

= Abstract =An autopsy case is described of a premature closure of the foramen ovale with a marked dilatation of the left atrium and an intact ventricular septum with aortic atresia but without left ventricular hypoplasia. This 28-week-old male baby was a stillborn to a 34-year-old multiparous mother. An intrauterine sonogram revealed marked ascites with anasarca, an enlarged left atrium and ve...

In this paper, we present a sensor guided ablation procedure of highly motile left atrium. It uses a system which automatically registers the 4D heart model with the position sensor on the catheter, and visualizes the heart model and the position of the catheter together in real time. With this system clinicians can easily map the motile left atrium shape and see where the catheter is inside it...

OBJECTIVE To establish the determinants of the peak VO2 in heart transplant recipients. METHODS Patient's assessment was performed in two consecutive days. In the first day, patients performed the heart rate variability assessment followed by a cardiopulmonary exercise test. In the second day, patients performed a resting echocardiography. Heart transplant recipients were eligible if they wer...

Our understanding of the left atrium is growing, although there are many aspects that are still poorly understood. The left atrium size as an imaging biomarker has been consistently shown to be a powerful predictor of outcomes and of different cardiovascular disorders, such as, but not limited to, atrial fibrillation, congestive heart failure, mitral regurgitation and stroke. Left atrial functi...

One of the generally recognized factors contributing to the initiation and maintenance of atrial fibrillation (AF) is structural remodeling of the myocardium that affects both atrial cardiomyocytes as well as interstitium. The goal of this study was to characterize morphologically and functionally interstitium of atria in patients with AF or in sinus rhythm (SR) who were indicated to heart surg...
