introduction tetralogy of fallot (tof) in the absent of pulmonary valve is a rare congenital anomaly (3%of tof patients). case presentation we are presenting an 18- year-old male with history of dyspnea on exertion and cyanosis since childhood. despite the diagnosis of congenital heart disease, no intervention was done due to his poor socioeconomic culture. at age of 18, he referred to our cent...

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...

THE experimental production of sudden, severe aortic insufficiency causes left ven-tricular diastolic pressure to become markedly elevated so that it exceeds left atrial pressure and results in diastolic closure of the mitral valve.' Ten cases of severe aortic insuffi-ciency have been reported in which left ven-tricular pressure exceeded left atrial pressure during diastole, causing premature m...

OBJECTIVE To study the early function of the bovine jugular vein (BJV) when used for right ventricular outflow tract (RVOT) reconstruction during the Ross procedure. METHODS Seventeen consecutive patients (median age, 12 years; range, 30 days to 40 years) who had undergone a Ross procedure with RVOT reconstruction using a BJV were reviewed. Nine patients had prior balloon valvotomy (n = 6) an...

A 31 year old woman was hospitalized for evaluation of aortic valve insufficiency and her present cardiac status. Clinical and paraclinical findings strongly suggested the presence of a collagen vascular inflammatory processprecisely, the antiphospholipid antibody syndrome (APS), with systemic lupus erythematosus as the underlying disease.

BACKGROUND Lhasa is the main residence of Tibetans and one of the highest cities in the world. Its unique geography and ethnic population provide the chance to investigate the interactions among high altitude, ethnicity, and cardiac adaptation. Meanwhile, echocardiographic data about healthy Tibetans on a large scale are not available. This study aimed to analyze physiological factors related t...

Disruption of pulmonary valve integrity after Tetralogy of Fallot repair often results in a cascade of hemodynamic and electrophysiological abnormalities. Here we report an uncommon case of severe pulmonary regurgitation with concomitant rheumatic mitral stenosis diagnosed 25 years after primary Tetralogy of Fallot repair. A 33-year-old man presented with symptomatic palpitation and exercise in...

OBJECTIVE Stentless porcine valves are commonly used for aortic valve replacement in adults, yet their long-term performance in the right ventricular (RV) outflow tract is unknown. We evaluated intermediate-term performance of stentless porcine valves in the RV outflow tract in 150 children and adults over a 10-year period. METHODS We retrospectively reviewed data on all patients undergoing p...
