Truncus solitarius pulmonalis.

The case of a female neonate with truncus solitarius pulmonalis (TSP), a rare congenital heart anomaly, is reported. She died four days after birth. A single right ventricle with common atrioventricular (AV) valve was associated with (Collet & Edwards type II) truncus arteriosus communis, and appeared to have a single coronary artery with an abnormally high take-off near the origin of the right subclavian artery. However, the vessel that appeared to be the single coronary artery was in fact an extremely hypoplastic ascending aorta associated with aortic atresia and agenesis of the left ventricle and mitral valve.

[Right ventricular regional wall motion and function after tetralogy repair].

The right ventricular (RV) function is very important after correction of tetralogy of Fallot (TOF) similarly to left ventricular (LV) function. The influence to RV contraction caused by RV outflow tract patch after repair of TOF is serious. There are a few literatures about contraction mode of RV but we can't see any reports about regional RV wall motion before and after surgery of TOF. This paper is the first report about RV regional wall motion and function after 20 cases of tetralogy repair. We would emphasize the following points. 1) Regional wall motion of RV at antero-basal and anterolateral is getting worse but is improved at anteroapical of RV. 2) Appropriate rate of RV systolic pressure to LV systolic pressure just after weaning from cardiopulmonary bypass and rate of patch length to RV length is below 0.5 and 0.4 respectively. 3) There is positive correlation between RV ejection fraction and wall motion at anteroapical of RV.

Double outlet right ventricle with severe left ventricular outflow tract obstruction due to small ventricular septal defect and anomalous adherence of the mitral valve to the ventricular septum.

A 1-month-old male infant with a double outlet right ventricle complicated by left ventricular outflow tract obstruction due to a very small ventricular septal defect is described. The atrial septum was intact, but mitral stenosis was present. The characteristic finding in this patient was that the inherently small ventricular septal defect was further narrowed by abnormal adherence of the anterior mitral leaflet to the left ventricular septal surface below the defect. Intracardiac anatomical features other than the adherent mitral valve could be evaluated accurately by two-dimensional echocardiography. Because the atrial septum was intact, balloon atrioseptostomy was not possible. An attempt at surgical creation of an atrial septal defect was unsuccessful, and the patient died immediately after the operation. The autopsy findings of the heart are described, and diagnostic problems and the possibility of radical operation are discussed.

Idiopathic myocarditis characterized by marked right ventricular dilatation. Report of two autopsy cases.

We encountered two children with chronic idiopathic myocarditis accompanied by marked right ventricular dilatation, who died of progressive right heart failure. A definitive diagnosis was made by histological examination of the myocardium at autopsy. The patients were both boys, aged 7 years and 1 year and 4 months, and a number of identical features were evident upon physical and laboratory examinations. No heart murmur was heard, and gallop rhythm was noted in distant heart sounds. Electrocardiogram revealed intraventricular block, low voltage QRS complex, and ST-T abnormality. Two-dimensional Doppler echocardiogram and right ventriculogram showed marked dilatation and decreased contractility of the right ventricle as well as tricuspid regurgitation. Thinning of the wall and marked dilatation of the right ventricle were confirmed at autopsy. Our observations showed that chronic myocarditis associated with tricuspid regurgitation may readily lead to marked right ventricular dilatation even exceeding the degree of left ventricular dilatation. Idiopathic myocarditis associated with such unusual features is relatively rare, and may present problems in differentiation from other congenital heart diseases causing dilatation and dysfunction of the right ventricle.

Unique types of criss-cross heart.

Three cases of criss-cross heart which we have observed during last five years are described. All of these cases were diagnosed by angiocardiography and two-dimensional echocardiography, and one of them was verified by autopsy. Two of them are unique among cases reported thus far. Case 1 shows ordinary criss-crossing with supero-inferior ventricle, and case 2, extreme crossing atrioventricular (A-V) valves, in which the right-sided right atrium connects to the left posteriorly positioned right ventricle through the tricuspid valve, and the left-sided left atrium to the right anterior left ventricle via a posteriorly positioned mitral valve. In case 3, the criss-cross appearance is secondary to displacement of the heart by compression caused by a diaphragmatic hernia. Findings in these cases suggest that criss-cross heart is caused not only by primary rotation of the ventricles during cardiac morphogenesis but also by secondary rotation of a formed heart induced by extracardiac compression. The degree of rotation in these cases revealed a wide spectrum from minimal to extreme. In addition, subxiphoid two-dimensional contrast echocardiography is recommended as the only accurate method of non-invasive diagnosis of this condition.

Morphological study of ventricular septal defect associated with obstruction of the aortic arch among Japanese.

This report describes racial differences in the morphology of ventricular septal defects associated with coarctation or interruption of the aortic arch. Twenty-three heart specimens with obstruction of the aortic arch associated with ventricular septal defects collected in southern Japan were studied. Six specimens had an interrupted aortic arch and the remaining 17 cases had coarctation of the aorta. Fifteen cases (65.2% of the total) had malalignment defects with posterior deviation of the conal and/or truncal septum. In contrast to Anderson's report, only one case of perimembranous defect with aortic overriding was seen in our series. These anatomical findings suggest that the majority of ventricular septal defects associated with coarctation or interruption among Japanese is a malalignment defect with left ventricular outflow tract obstruction.
