Muscular ventricular septal defects (mVSDs), whether dealt with as a single lesion or as a complex of congenital heart disease, are fraught with difficulty. Pulmonary artery bands are palliative, and ventriculotomies initiate scarring. Simple single mVSDs are difficult to visualize from a right atrial approach because they are commonly in the apex, whereas multiple mVSDs have muscular septations within the right ventricular cavity, making it difficult to visualize a defined edge for optimal patch opposition, leaving residual shunts. Transcatheter occluders have been placed in the ventricular septum percutaneously,1
perventricularly,2,3
and intraoperatively.4
In general, a significant amount of experience and resources are necessary to perfect the percutaneous/perventricular techniques, whereas the direct intraoperative approach is more straightforward. Furthermore, cardiopulmonary bypass (CPB) is often necessary for other associated complex congenital lesions. We present a simple hybrid-type approach to close mVSDs during cardioplegic arrest using an Amplatzer duct occluders (AGA Medical, Golden Valley, Minn) through the left atrium in a patient with D-transposition of the great arteries.
