Bigeminy and the bifid papillary muscle
Various structural anomalies of the left ventricular papillary muscles have been observed in recent years. Many of these have been linked to electrocardiographic aberrations. Recently two reports have appeared where the base of the posterior papillary muscle was identified as the source of frequent premature ventricular complexes. In some of these patients these frequent premature ventricular c...
متن کاملPapillary Fibroelastoma of the Papillary Muscle of the Tricuspid Valve: Reconstruction of the Papillary Muscle*
Cardiac papillary fibroelastoma is the third most frequent primary cardiac tumor, after myxoma and fibroma. A papillary fibroelastoma that arises from the papillary muscle is rare. We removed a papillary fibroelastoma located at the anterior papillary muscle of the tricuspid valve. The papillary muscle needed reconstruction. We used the loop technique to adjust the length of the papillary muscl...
متن کاملRuptured Papillary Muscle
RUPTURE of a papillary muscle is a rare complication of myocardial infarction.1 2 The combination of coronary artery disease with severe mitral regurgitation usually results in a rapid, deteriorating course. Not until 1948 was this diagnosis correctly made ante mortem.3 Sanders et al., in 1957, discussed 61 cases of rupture of a papillary muscle and pointed out the important clinical features o...
متن کاملPapillary Muscle Arrhythmias
Technological advances during the past decade have significantly enhanced our ability to successfully map and ablate ventricular arrhythmias in patients with a structurally normal heart, as well as various forms of underlying cardiac disease. Increased recognition of the deleterious effects of ventricular arrhythmias, such as the potential of frequent premature ventricular complexes (PVCs) to i...
متن کاملBigeminy on exertion.
BIGEMINY or coupling of beats may involve the atria alone, the ventricles, or both. There are many causes for coupling, the commonest and most important being extrasystoles.1 In extrasystolic bigeminy, there is a premature contraction after each normal beat. The premature beat may orig-immate from the sinoatrial node, the atrium, the atrioventricular node, the atrioventricular bundle, or the ve...
