OBJECTIVES The aim of the present investigation was to redefine the clinicopathologic profile of arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC), with special reference to disease progression and left ventricular (LV) involvement. BACKGROUND Long-term follow-up data from clinical studies indicate that ARVC is a progressive heart muscle(More)
In this issue of Circulation, Burke et al 1 report the results of a morphological and morphometric analysis of RV myocardium to differentiate fatty infiltration of the RV free wall from fibrofatty infiltration, which is the histological marker of ARVC. A similar analysis was previously presented by Thiene et al, classifying their patients as having(More)
BACKGROUND Arrhythmogenic right ventricular dysplasia, a disorder that may lead to severe ventricular arrhythmias and sudden death, is characterized by the progressive replacement of myocardial cells by fat and fibrous tissue. We examined whether the loss of myocardial cells in this disease could result from cell death by apoptosis (programmed cell death).(More)
Anatomical characteristics of the radial a. were compared to those of the internal thoracic a., considered as a gold standard in coronary surgery. The length, the diameter, the collateral distribution and the wall thickness of these two arteries were studied comparatively. In addition, a comparative histological analysis was carried out. Anatomical and(More)
In our approach to dynamic cardiomyoplasty, which consists of wrapping a skeletal muscle around the heart and stimulating the former in synchrony with heart contractions to augment ventricular contractility, we have transferred a latissimus dorsi muscle flap to the heart by way of a partial resection of the second rib and subsequently suturing the muscle(More)
Five patients were studied 5-13 months after dynamic cardiomyoplasty for refractory heart failure. In two, muscle flap stimulation caused a pronounced increase in cardiac index (mean 55%) and ejection fraction (mean 75%); no patient showed improvement in cardiac filling pressure. 2 years after surgery, one of the patients with haemodynamic improvement died(More)
Fat that is well demarcated from underlying muscle is found on the right ventricular free wall and around epicardial coronary vessels. Fat is not present in the left ventricle in normal subjects. In right ventricular dysplasia, fat and fibrosis may massively displace right ventricular myocardial tissue. It is frequently associated with some clusters of fat(More)
The increasing number of arrhythmogenic idiopathic cardiomyopathies with available histological studies by biopsy or peroperative sampling has prompted the need for data about the normal structure of the right ventricle. A retrospective study of right ventricular tissues was undertaken in 148 autopsies. The quantity of adipose tissue was scored 0 (only(More)
Sudden death is rare in athletes, and it is only in recent years that significant series were collected, making it possible to draw the cardiological profile of athletes who died suddenly at the peak of exertion or while recovering. A study of the literature, both medical and paramedical, has yielded 53 cases in which the most frequent causes of sudden(More)
