HeartMate 3 implantation for dextro-transposition of the great arteries after Mustard procedure: A technique of papillary muscle repositioning.

Systemic right ventricular failure after physiologic repair for dextro-transposition of the great arteries can be managed with durable mechanical circulatory support; however, the right ventricular morphology, such as intervening papillary muscles, presents challenges to inflow cannula positioning. Papillary muscle repositioning is an innovative technique to circumvent obstructive anatomy.
