This is a case of a female infant with bilateral coronary ostial atresia associated with pulmonary atresia and ventricular septal defect. She developed coronary ischemia at 1-month of age, when she underwent an aortopulmonary shunt and an aorta-right ventricle shunt. The double-orifice tricuspid valve was separating the right ventricle from the left ventricle. She required extracorporeal cardiopulmonary support because of ventricular dysfunction and mitral regurgitation. Although she was temporarily weaned off the support after mitral valvuloplasty, she died from multiple organ failure. To the best of our knowledge, bilateral coronary ostial atresia associated with pulmonary atresia with ventricular septal defect has not been reported previously.

We describe an atypical case of an atrioventricular septal defect with a common atrioventricular junction in which the right-sided component of the common atrioventricular valve was imperforate, producing tricuspid atresia with a severely hypoplastic right ventricle and an ostium primum defect. We discuss the implications of the anatomic findings with regard to concepts of cardiac development, drawing a comparison with similar cases previously reported.

The objective of this study was to review the echocardiographic findings and autopsy correlates of pulmonary atresia with an intact ventricular septum when diagnosed during fetal life. All cases with this lesion (nearly 60) seen in the Perinatal Cardiology unit of Guy's Hospital since 1983 are part of this study. More than half of the cases were detected within the last two years, and all bar three were referred because of suspicion of a cardiac malformation detected on routine obstetric scanning. The cases were divided into two distinct groups. On the one hand were those with dilatation of the chambers of the right heart. These had a uniformly poor prognosis. Severe regurgitation of the tricuspid valve was a characteristic feature. On the other hand were the cases with cavitary hypoplasia due to mural overgrowth. Direct measurements of pressure in one such case revealed suprasystemic values in the right ventricle. Although contemplated, fetal intervention proved impossible. Autopsy revealed cases with either valvar or infundibular atresia. In most cases diagnosed prior to 24 weeks of gestation, mothers opted for termination of pregnancy. All cases with dilatation of the right ventricle died. Of pregnancies which continued, only 30% of children are still alive, all but one being less than two years of age at present. The use of cross-sectional and Doppler echocardiography permits the accurate diagnosis of pulmonary atresia with an intact ventricular septum during fetal life. Autopsied cases showed strong correlation with the echocardiographic findings. The poor prognosis in most cases warrants consideration in the future of intervention during fetal life.

A child presented at birth with severe cyanosis. Echocardiography showed hypoplasia of the right heart with a right-to-left shunt at atrial level. A conservative approach was adopted initially, and the situation improved over a few months, with reversal of the atrial shunt. Surgery was successfully performed at 4 years of age after further echocardiography revealed a congenitally large Eustachian valve and an atrial septal defect.

Objectives: We sought to determine trends, and outcomes, for a cohort of patients with pulmonary atresia with intact ventricular septum born between 1965 and 1998. Background: Pulmonary atresia with intact ventricular septum is a complex lesion that remains a therapeutic challenge, particularly regarding the suitability for biventricular repair. Methods: We identified 210 consecutive patients, and reviewed their medical records, initial angiograms, and echocardiograms, along with the relevant surgical and pathology reports. Results: The mean initial Z-score for the diameter of the tricuspid valve was −0.99 ± 1.95, with Ebstein's malformation in 8%. A right ventricular dependent coronary arterial circulation was found in 23%. The proportion of patients who received treatment increased over time, although placement of an arterial shunt was the predominant initial procedure throughout the experience. At the last follow-up, 107 patients had not reached the planned final stage of their repair, and 79% of these had died. Of the 103 reaching the final stage of planned repair, 58 had undergone attempted biventricular repair, with 34% dying; 14 had undergone attempted one and a half ventricular repair, with 7% dying, and 31 had undergone attempted functionally univentricular repair, with 10% dying. Overall, survival was 57% at the age of 1 year, 48% at 5 years, and 43% at 10 years. Survival improved over time, with survival of 75% at 1 year, and 67% at 5 years, for patients born between 1992 and 1998. An earlier date of birth, the presence of Ebstein's malformation, and prematurity were all significant independent factors associated with decreased survival. A greater severity of coronary arterial abnormalities was significantly associated with a greater likelihood of left ventricular dysfunction during follow-up. Conclusions: The outcomes for patients born with pulmonary atresia with intact ventricular septum have improved over time, albeit that careful initial management, and better selection, is still indicated for those planned to undergo biventricular repair.
