BACKGROUND Ebstein anomaly and tricuspid valve dysplasia are rare congenital tricuspid valve malformations associated with high perinatal mortality. The literature consists of small, single-center case series spanning several decades. We performed a multicenter study to assess the outcomes and factors associated with mortality after fetal diagnosis in the current era. METHODS AND RESULTS Fetu...
The efficacy of balloon dilatation of the mitral valve by a bifoil (2 x 19 mm) or trefoil (3 x 15 mm) catheter (single catheter technique) was assessed in 53 patients (mean age 28) with mitral stenosis, most of whom were women. The procedure was unsuccessful in three patients. After balloon dilatation the left atrial pressure decreased from 22 mm Hg to 13 mm Hg and the mitral valve gradient fro...
ebstein's anomaly is defined as the significant apical displacement of the tricuspid valve causing tricuspid regurgitation. although a variety of concomitant lesions have been previously described, we herein introduce an unusual presentation. our patient was an 86-year-old man with a primary presentation of typical chest pain in the setting of recently diagnosed coronary artery disease with co...
The long-termfollow-up over a period of2 to 5years of thefirst 7 survivors of complete correction with homograft reconstruction in pulmonary outflow atresia and extreme Fallot has been studied. Symptomatically, the patients have remained excellent with return to normal of the chest x-rays and electrocardiograms. Investigation has shown continued good function of the homograft aortic valve in th...
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...
Continuous-wave Doppler echocardiography was used to estimate pulmonary artery pressures by measuring pulmonary regurgitant flow velocity in 21 patients with pulmonary hypertension (mean pulmonary artery pressure 20 mm Hg) and 24 patients without pulmonary hypertension. The pulmonary regurgitant flow velocity patterns, characterized by a rapid rise in flow velocity immediately after closure of ...

Pulmonary regurgitation after repair of tetralogy of Fallot has always been an important issue for pediatric cardiac surgeons. Some of the patients may need pulmonary valve replacement in the future. Conventional prosthesis valves were seldom custom made for the pulmonary valve and were often inadequate to use because of variable age and size of these patients. Through evolution of techniques, ...
We previously reported that pulmonary artery pressures can be assessed in children with chronic rheumatic mitral valve disease by measuring right maximum spatial vector from Frank vectorcardiogram. To simplify the calculation, pulmonary artery systolic pressure was correlated with maximum negative deflection on Frank scalar X-lead (SX), maximum negative deflection on scalar Z lead (SZ), sum tot...
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 ...
