The Beat With Joel Dunning Ep. 99: CT Scan-Negative Type A Dissection

This week on The Beat, CTSNet Editor-in-Chief Joel Dunning speaks with Dr. Salim Aziz, thoracic and cardiovascular surgeon and clinical professor at George Washington University, about computed tomography (CT) scan-negative type A dissection.

25:17 Dr. Aziz, CT Scan-Negative Type A Dissection

43:52 Closing

They discuss Dr. Aziz’s experience with cases that present as CT scan-negative, discussing the details of these cases and the concerning frequency with which aortic dissections are overlooked. They also explore routine transesophageal echocardiogram (TEE) in the operating room, finding tears, and aortic aneurysms.  

Joel also reviews recent JANS articles on the ambulation protocol for adult patients receiving extracorporeal membrane oxygenation, if the severity of chronic obstructive pulmonary disease is associated with adverse outcomes after open thoracoabdominal aortic aneurysm repair, the learning curve of robotic mitral repair, and long-term outcomes following the Ross procedure in neonates and infants.  

In addition, Joel explores a 2024 London Core Review Cardiothoracic Surgery Course on “Surgical Treatments of Aortic Root Aneurysms,” aortic valve replacement 101 through an upper ministernotomy, and robotic beating-heart totally endoscopic coronary bypass. Before closing, he highlights upcoming events in CT surgery.
