A 76-yr-old man with unipolar ventricular pacemaker, previously implanted in the right ventricular apex, presented with syncopal attack and twitching of the right pectoralis muscle. He finally was diagnosed as having Twiddler's syndrome. The patient had a pulse rate of 36/min and cannon waves in the neck veins. Chest radiography showed a dislodged pacing lead completely wrapped around the pulse...

Introduction: The correlation between right and left ventricular ejection fractions (RVEF and LVEF, respectively) has been studied in only a small number of patients with a marked decrease in RVEF and LVEF. The aim of the present study was to compare LVEF and RVEF in patients with ischemic heart disease. RVEF and LVEF were measured by Cardiovascular Magnetic Resonance (CMR) imaging. Materials a...

acute inferior myocardial infarction (mi) frequently involves the right ventricle (rv).1-3 we assessed the prognostic impact of rv myocardial involvement in patients with inferior mi. one hundred seventy patients were admitted to the cardiac care unit of madani heart hospital (tabriz-iran) with the diagnosis of inferior mi with (group1) or without (group2) the simultaneous involvement of rv dur...

a 47 year-old female died after mitral valve replacement. post-cardiopulmonary bypass right ventricle was not able to pump despite good left ventricular contractility. at microscopic examination, diffuse right ventricular fatty infiltration was found. we found no previous report of this pathology in patients with mitral stenosis

conclusions full echocardiographic examination of the right ventricle, including rvot is essential for the diagnosis of this disease. surgical correction appears to be a successful strategy for management of this rare condition in adults. case presentation we report a 40-year-old man who was referred to cardiology clinic for work-up of dyspnea and a heart murmur found on his physical examinatio...

the optimal treatment method for right ventricular failure after valve surgery complicated by a low cardiac output has not been determined, although several case reports have been published on patients with ventricular failure and arrhythmia who were bridged to cardiac transplantation using biventricular or left ventricular assist devices. this case series illustrates successful circulatory sup...
