[Surgical treatment of left ventricular-right atrial communication].

Four cases of congenital left ventricular-right atrial communication were presented. Correct diagnoses were made in two cases before operation by left ventriculography. The other two cases were misdiagnosed as ASD or VSD by right heart catheterization and ventriculography. After surgical repair under cardiopulmonary bypass, they were all cured and discharged. During the follow-up period, one patient with residual leak was reoperated upon and died on the sixteenth postoperative day from arrhythmia and heart failure. The other three patients secured complete restitution.
