Pulmonary hypoplasia(PH) commonly occurs in association with oligohydramnios and other congenital anomalies, especially congenital diaphragmatic hernia (CDH). Pulmonary hypoplasia is an important factor, as persistent pulmonary hypertension, in the prognosis of CDH. In some reports, there is a decrement of pulmonary surfactant in PH accompanying CDH. Recently, there are some ...

Congenital diaphragmatic hernia through the foramen of Bochdalek usually presents with severe respiratory symptoms soon after birth. Despite successful repair of the defect the mortality rate still remains high. This may be due to co-existing pulmonary hypoplasia with pulmonary hypertension and concomitant right-to-left shunting. In order to find factors that ...
Ganeshakrishnan K I - - 1992
An interesting case of congenital intrapericardial aneurysm of the left-atrial appendage is reported. The patient presented with recurrent supraventricular arrhythmias and progressive exercise intolerance and fatigue. Computerised axial tomography aided in the diagnosis by excluding the presence of any thrombus in the sac. The aneurysm could be safely excised via ...
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 ...
