The Beat With Joel Dunning Ep. 121: Managing LVOT Obstruction With Minimal Septal Hypertrophy

This week on The Beat, CTSNet Editor-in-Chief Joel Dunning speaks with Dr. Nicholas Smedira, a cardiac surgeon at the Cleveland Clinic, about mitral valve-induced left ventricular outflow tract (LVOT) obstruction with minimal septal hypertrophy. They discuss the importance of understanding the anatomy and physiology of the papillary muscles, as well as flow vortices. They also cover various techniques for mitral valve repair and replacement, emphasizing the importance of making the leaflet coaptation zone as posterior as possible. Additionally, they explore how learning techniques for mitral valve-induced LVOT obstruction with minimal septal hypertrophy have evolved through exposure and experience.  

Joel also highlights recent JANS articles on the world's first transcervical robotic AVR procedures successfully performed in four Cleveland Clinic patients, a comparison of outcomes post Cor-Knot vs manual tying in valve surgery, endobronchial valve therapy vs lung volume reduction surgery in the United States, and early extraction vs conservative management in patients with noninfected cardiac implantable electronic devices undergoing cardiac surgery for left-sided infective endocarditis.  

In addition, Joel explores the repair of a ruptured right coronary artery aneurysm, removal of a right atrial myxoma from the IVC junction with patch repair using the left atrial appendage, and a modified redo Commando procedure in a patient with septic shock due to aortic and mitral valve endocarditis. Before closing, Joel highlights upcoming events in CT surgery.
