Removal of a Right Atrial Myxoma From the IVC Junction With Patch Repair Using the Left Atrial Appendage
Gaudiani V, Tsau P. Removal of a Right Atrial Myxoma From the IVC Junction With Patch Repair Using the Left Atrial Appendage. August 2025. doi:10.25373/ctsnet.29983018
In this video, Dr. Vince Gaudiani demonstrates how to remove a right atrial myxoma in a 45-year-old patient who presented with a cerebralvascular accident (CVA).
He performed a sternotomy and highlighted the importance of not manipulating the heart until it was cross-clamped to prevent any debris from being displaced and embolized. He opened the venous drainage line first and then cross-clamped the aorta before going on bypass to maintain laminar flow around the heart.
Once cross-clamped, cardioplegia was administered, and a vent was placed. This large tumor was removed, and the stump was also followed down near the inferior vena cava (IVC), near the coronary sinus, and near the triangle of Koch. This base was excised and then repaired using the left atrial appendage, which was stapled and used as a patch for the IVC, as the IVC had been excised down to the diaphragm.
