A 32-year-old woman with a history of tetralogy of Fallot (TOF) was referred for cardiac evaluation. She was diagnosed with TOF as an infant and at 8 months of age underwent complete repair, including ven-tricular septal defect closure, resection of right ventricular (RV) outflow tract (RVOT) muscle bundles, and pulmonary valvotomy. She was evaluated by a cardiologist at 17 years of age and was...
BACKGROUND The use of a pulmonary autograft for rereplacement of the aortic valve has both potential advantages and disadvantages. This study details the early results of a subset of patients enrolled in a prospective randomized trial comparing pulmonary autografts and aortic homografts who have had previous aortic valve replacements. METHODS AND RESULTS A total of 47 patients who had undergo...
We report a 13-year-old girl with acute pulmonary edema due to severe acute Mitral regurgitation because of rupture of Mitral valve ́s posteromedial papillary muscle. She had normal mitral valve with necrotic posteromedial papillary muscle, classic aneurysms in left coronary artery, neutrophilic infiltration in the wall of medium-sized vessel of kidney and positive perinuclear antineutrophil cyt...
Homograft valve replacement of the diseased aortic valve with a homologous aortic valve inserted in the sub-coronary position was first performed in July 1962 (Ross 1962). The procedure of transferring the patients autologous pulmonary valve to the aortic position has been used since 1967 (Ross 1967). The long term performance of homograft vaives has not been regarded as satis facrory in some c...
BACKGROUND Carcinoid heart disease typically results in pulmonary stenosis and tricuspid incompetence. Percutaneous balloon dilatation is an effective treatment for congenital pulmonary stenosis and has been applied successfully to tricuspid stenosis caused by carcinoid heart disease. The value of balloon dilatation of the pulmonary valve in carcinoid pulmonary stenosis was assessed. METHODS ...
conclusions children with chd are at risk of severe complications with the involvement of other organs. long-term febrile illness should be taken seriously in these children. they need hospitalization and careful evaluation. case presentation a 6-year-old girl with a ventricular septal defect (vsd) was presented. echocardiography revealed large vegetation in the right ventricular outflow tract ...
OBJECTIVE To identify perioperative clinical predictors of permanent pacemaker implantation following aortic valve replacement. DESIGN AND PATIENTS Prospective cohort study on 276 patients submitted for aortic valve replacement: 267 patients (mean (SD) age, 57.5 (14) years) with no conduction disturbances, and nine patients (67.7 (5) years) with severe conduction disturbances requiring perman...
Introduction: Rheumatic heart disease still remains one of the leading causes of congestive heart failure and death owing to valvular pathologies, in developing countries. Valve replacement still remains the treatment of choice in such patients.The aim of this study wasto analyze the postoperative outcome of double valve replacement (Mitral and Aortic ) in patients of rheumatic heart disease. ...
