The Beat With Joel Dunning Ep. 165: Valve-Sparing Aortic Root Replacement Techniques

This week on The Beat, CTSNet Editor-in-Chief Joel Dunning spoke with Dr. Chris Malaisrie, a Professor of Surgery in the Division of Cardiac Surgery at Northwestern University and an Attending Cardiac Surgeon at Northwestern Medicine, about valve-sparing aortic root replacement techniques.

The conversation covers a wide range of procedures, including the Bentall, Yacoub, and David operations, as well as the Ross procedure and personalized external aortic root support (PEARS). They further explore approaches to mitral and aortic valve repair, the management of diseased leaky valves, and the advantages of the Stanford modification of the David V procedure. Dr. Malaisrie concludes the discussion by offering advice to surgeons on refining their valve repair skills and shares his prediction for the future of valve repair surgery.

Joel also highlights recent JANS articles on age vs lifetime perspective on the transcatheter vs surgical aortic valve implantation, gene-edited pig cardiac xenotransplantation as a bridge to allotransplantation in infants, long-term outcomes of postoperative atrial fibrillation after cardiac surgery, and a case on ice water drowning survival after 147-minute submersion and 7 °C hypothermic circulatory arrest.

In addition, Joel explores double annular enlargement as an effective technique to overcome patient-prosthesis mismatch, reoperation for aortic root reconstruction, and normothermic treatment of an aortic arch aneurysm.

Before closing, Joel highlights upcoming events in CT surgery.
