Abstract

Heart failure remains a major global problem with approximately 6 million individuals suffering from heart failure in the United States alone. The surgical technique of heart transplantation, popularized by Dr. Norman Shumway, has led to its success and currently remains the best treatment options for patients with end-stage. However, with the continued limitation of donor organs and the rapid development of ventricular assist device technology, the number of patients bridged to transplant with mechanical circulatory support has increased significantly. This has created some new technical challenges for heart transplantation. Therefore, it is now important to be familiar with multiple new technical challenges associated with the surgical techniques of heart transplantation with an ultimate goal in reducing donor heart ischemic time, recipient cardiopulmonary bypass time and post-operative complications. In this review, we described our technique of heart transplantation including the timing of the operation, recipient cardiectomy and donor heart implantation.

(A) A redo-sternotomy in a patient with previous LVAD placement. Rult retractor (Rultract, Cleveland, OH) was used to assist in exposure for the dissection of the left ventricular apex and LVAD. (B) Completion of the dissection with LVAD outflow graft and LVAD driveline exposed. Snares were placed around the SVC and IVC. LVAD, left ventricular assist device; SVC, superior vena cava; IVC, inferior vena caca.

Completion of the recipient cardiectomy with aorta cross-clamped and vena cavae snared. IVC cannulation was done via the right common femoral vein. SVC, superior vena cava; IVC, inferior vena caca.

(A) LVAD driveline was divided and outflow graft was clamped and divided; (B) Recipient heart was resected along with the LVAD. LVAD, left ventricular assist device.

Back table donor heart preparation. The left atrial appendage incision was closed and the left atrial cuff was created. The donor heart was examined for patent ductus ovale, valvular abnormality and congenital anomaly.

The illustration on the right showed the completion of a bicaval orthotopic heart transplantation. PA, pulmonary artery; PV, pulmonary vein; SVC, superior vena cava; IVC, inferior vena caca.
