Abstract
OBJECTIVES
To describe the morphology, echocardiographic features and surgical management of the entity appropriately described as 'double outlet of both ventricles'.
METHODS
Seven patients (5 males, age 0.5-7.5 months) were diagnosed to have a unique form of subarterial ventricular septal defect (VSD) and ventriculo-arterial connection, where a muscular outlet septum straddled the crest of the ventricular septum in a cruciate manner, such that both great arteries were equally committed to both ventricles. Diagnosis was established by echocardiography, with 6 patients submitted to surgical repair by means of intracardiac routing of the left ventricle to the aorta using 2 patches.
RESULTS
Surgical repair was successful in all 6 patients in whom it was attempted. In addition, 1 patient underwent concomitant repair of aortic coarctation, and 2 had closure of multiple VSDs. We lost 1 patient to follow-up after diagnosis. Follow-up with a range from 3 months to 8 years in the remaining patients revealed all to be clinically well with satisfactory growth of both outflow tracts.
CONCLUSIONS
We describe a series of patients with the ventriculo-arterial connection best described as 'double outlet of both ventricles'. Diagnosis is readily established by echocardiography. Good early and midterm results can be expected subsequent to surgical repair using 2 patches for interventricular septation.
