Nakayama D K - - 1992
Pulmonary hypertension is a major source of morbidity and mortality in infants born with congenital diaphragmatic hernia (CDH). Increased pulmonary vascular resistance leads to right-to-left shunting, which is evident as decreases in the PaO2 measured in postductal arterial blood. Thromboxane A2 (TXA2), a vasoconstrictor, and prostacyclin (prostaglandin I2, PGI2), a ...
Niinami H - - 1992
A right coronary artery originating from the left coronary sinus and traversing anteriorly is thought to be one of the contraindications for a Konno aortoventriculoplasty in congenital aortic stenosis because this procedure necessitates incision of the right ventricular outflow tract. The case of a 5-year-old girl with congenital aortic stenosis ...
Fontana G P - - 1992
Intraoperative echocardiography in the evaluation of congenital heart defects is a useful method to evaluate surgical anatomy, adequacy of repair, and ventricular performance. Since 1987, 733 patients have undergone epicardial echocardiography during repair. The routine use of this technique has led to the reduction in the need for both early ...
Warren E T - - 1992
Pulmonary artery banding is indicated in numerous congenital cardiac defects not amenable to a total repair.
