Correlative angiographic-anatomical studies in 19 cases of pulmonary atresia with infarct ventricular septum showed the following relations between the angiographic appearance of the pulmonary valve and the morphology of the right ventricle. (1) Doming of the pulmonary valve was associated with a nearly normal-sized right ventricle and a wide infundibulum patent to the level of the pulmonary va...

aly characterized by the absence of the pulmonary valve. The absence of the pulmonary valve, along with the hypoplasia of the pulmonary annulus, leads to aneurysmal dilatation of the pulmonary artery and its branches. Other consequences include pulmonary stenosis and pulmonary insufficiency (1). The 3-day-old baby presented with cyanosis and tachypnea. He had to and fro murmurs at the upper lef...

OBJECTIVE To assess the efficacy of arterial duct angioplasty in maintaining adequate ductal patency in neonates with critical pulmonary valve stenosis. PATIENTS Two neonates presenting with cyanosis due to critical pulmonary valve stenosis with severe right ventricular hypoplasia underwent percutaneous balloon dilatation of the pulmonary valve. Despite successful dilatation, both remained cy...

Monro, J. L., Gavin, J. B., and Barratt-Boyes, B. G. (1974). Thorax, 29, 323-328. A comparison of antibiotic-sterilized, stent-mounted pulmonary and aortic valve allografts in the mitral region of dogs. The mitral valves of 40 dogs were replaced with antibioticsterilized, stent-mounted semilunar valve allografts. Twenty grafts were pulmonary valves and 20 were aortic valves. Six dogs in each gr...

UNLABELLED A 67-year-old man with myelodysplastic syndrome, disseminated histoplasmosis, and mitral valve replacement presented with dyspnea and peripheral edema. Transthoracic echocardiography demonstrated abnormal pulmonic valve with possible vegetation. Color flow imaging showed laminar flow from main pulmonary artery into right ventricular outflow tract (RVOT) in diastole. The continuous wa...

Twenty nine patients (19 male, mean (SD) age 6.25 (0.5) years (range 0.16-15 years] with typical pulmonary valve stenosis were treated by balloon dilatation of the pulmonary valve. They were studied by echocardiography before the procedure, immediately after it, and at follow up (mean (SD) 10.2 (5.6) months, n = 18). The morphology of the pulmonary valve, the right ventricular-pulmonary artery ...

Three patients with normal hearts and no pulmonary abnormality had neonatal tricuspid regurgitation causing cardiorespiratory distress and cyanosis. The signs of tricuspid regurgitation resolved over a few weeks. In the acute phase echocardiography showed gross dilatation of the right atrium and ventricle. The interatrial septum bulged into the left atrium during the whole cardiac cycle. Dopple...

OBJECTIVE To evaluate the results of pulmonary valve replacement in patients with severe pulmonary regurgitation after tetralogy of Fallot repair in Hong Kong. DESIGN Retrospective review. SETTING University teaching hospital, Hong Kong. PATIENTS Consecutive patients undergoing pulmonary valve replacement after repair of tetralogy of Fallot between August 2002 and December 2008. MAIN OU...
