d i ( i a f r i v g ( Unraveling the mysteries of cardiac contraction has been a major preoccupation of the cardiac investigators. More recently, the right ventricle is in focus, especially the right ventricle in the systemic position. The differences between the right and the left ventricles in myocardial architecture, blood supply, metabolism, response to loading conditions, and embryological...

delayed evaluation and management of penetrating cardiac injuries especially mortar fragments were performed in 30 war victims in the shahid rajai heart hospital, tehran. all were men with a mean age of 20.7 years. pleuritic chest pain was the most common symptom (53.3%), while physical examination was negative in the majority of cases (66.8%). 50 percent of the cases had pericardial effusion o...

We describe a case of double outlet right ventricle with subaortic ventricular septal defect and pulmonary stenosis treated successfully with cardiopulmonary bypass. We consider the clinical history and angiocardiographic and surgical findings of this rare anomaly. We stress the difficulties of reconstruction of the outflow tract of the right ventricle, because of the anomalous pathway of the r...

Current dogma is that pathological hypertrophy of the right ventricle is a direct consequence of pulmonary vascular remodeling. However, progression of right ventricle dysfunction is not always lung-dependent. Increased afterload caused by pulmonary vascular remodeling initiates the right ventricle hypertrophy, but determinants leading to adaptive or maladaptive hypertrophy and failure remain u...

Abullet located in the interventricular septum is shown in frontal (A) and right lateral (B) chest radiography and in an echocardiogram (C; RA indicates right atrium; RV, right ventricle; LA, left atrium; and LV, left ventricle. Superior white arrow, labeled BULLET, shows the bullet located at the interventricular septum). It is from a 37-year-old policeman who was shot while on duty. The bulle...
