Automated left ventricle (LV) boundary delineation from left ventriculograms has been studied for decades. Unfortunately, no methods in terms of the accuracy about volume and ejection fraction have ever been reported. A new knowledge based multi-stage method to automatically delineate the LV boundary at end diastole and end systole is discussed in this paper. It has a mean absolute boundary err...

Congenital diverticulum of the left ventricle of the heart is considered to be a rare malformation. Up to 1958, Keith, Rowe, and Vlad could only collect 13 cases from the published reports. Successful operations had been recorded by Roessler (1944), Skapinker (1951), Potts, DeBoer, and Johnson (1953), and Mustard, Duckworth, Rowe, and Dolan (1958). The purpose of this paper is to present the cl...

Abnormal left ventricular trabeculations can be a cardiac manifestation of Becker’s muscular dystrophy. Abnormal left ventricular trabeculations in mitochondrial myopathy have not been reported before. A 68 year old man with a history of chronic congestive heart failure and hypertension, had recurrent raised creatine kinase (CK) concentrations (up to 150 U/l; normal 70 U/l) with normal CKMB iso...

ebstein anomaly is characterized by apical displacement of the septal and posterior tricuspid valve leaflets, leading to atrialization of the right ventricle and could be diagnosed in a routine transthoracic echocardiography exam. we reported a young man with right sided heart failure symptoms who was found to have biventricular failure with suspected apical displacement of septal leaflet of tr...

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...

one hundred and sixty one-day-old male broilers (ross 308) in a 6-wk period were conducted to 2 groups (with 4 replicates for each group), 20 chicks for a replicate. one group of these chickens was raised in normal temperature (nt) treatment and the other in cold temperature (ct) treatment to induce ascites. at the end of the experiment (wk 6), 2 chickens from each replicate were randomly selec...
