Objective: We tested a new surgical technique, the plication of the left ventricular free wall, to reduce left ventricular area and volume and improve left ventricular systolic function, without using a cardiopulmonary bypass. Methods: Dilated cardiomyopathy was induced in eight dogs by the injection of doxorubicin. Plication of the left ventricular free wall was performed in four dogs with ind...

a2-year-old cachectic cross-breed gelding was admitted toveterinary teaching hospital of university of tehran followingthe onset of a marked respiratory distress, coughing and ventraledema. clinical examinations indicated harsh respiratory andexpiratory sounds as well as jugular vein distention. therespiratory and heart rates were 35/min and 60 bpm, respectively.agrade iii/iv pansystolic murmur...

Pulmonary arterial hypertension is a malignant pulmonary vascular disease primarily caused by increased resistance, which leads to right ventricular hypertrophy, fibrosis, heart failure and death. Fragmented QRS (fQRS) indicates non-homogeneous activity myocardial fibrosis. This study aims investigate the importance of fQRS in patients with (PH) determine role presence indicating severity disea...

Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is an autosomal dominant genetic form of cardiomyopathy (CM), which primarily affects the right ventricle (RV) and results in life threatening ventricular arrhythmias and sudden cardiac death (SCD). Diagnosis is difficult due to the broad spectrum of phenoltypic variations, especially in the early stage. Clinical suspicion shoul...

Three patients with Emery Dreifuss muscular dystrophy are reported. Emery Dreifuss muscular dystrophy is an X linked muscular dystrophy, in which locomotor involvement is characteristically mild and slowly progressive. The effect on the heart becomes apparent in the teenage years and is characterised by cardiac conduction defects and infiltration of the myocardium by fibrous and adipose tissue....

A 20-year-old Coloured man gave a history of atypical chest pain, palpitations after strenuous exercise and a single episode of post-exertional presyncope. The diagnosis of hypertrophic non-obstructive apical cardiomyopathy (HNOAC) was established by means of electrocardiography, echocardiography (both M-mode and two-dimensional) and left ventricular cineangiography. This variant of hypertrophi...

This study describes a case of tetralogy of Fallot in a lamb showing failure to thrive and signs of respiratory distress. Physical examination, electrocardiography, thoracic radiographies, echocardiography and cardiac troponin I evaluation were performed. The value of cardiac troponin I was compared with the values of 10 healthy lambs of the same age and breed, and the affected animal demonstra...

A 76-year-old patient with a medical history of hypertension, type 2 diabetes mellitus and moderate valvular aortic stenosis underwent cephalic DDD pacemaker implantation because of fatigue and a 3rd degree atrioventricular block with a ventricular escape rhythm of 45 beats per minute. After implantation, he complained about stabbing chest pains. A chest radiograph did not reveal any signs of a...
