EP308: Myocardial Bridging—a Bridge Too Far

Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients. Doctor Warrick Bishop discusses heart disease risks and prevention on his podcast. He talks about an interesting presentation he saw on myocardial bridging, where the coronary artery runs through the heart muscle in 20% of people. This was thought to not impact blood flow, but can in rare cases limit flow and cause angina symptoms. This is a cause of MINOCA syndrome, where ischemia occurs despite clear arteries. Doctor Bishop describes diagnostic tests like CT scans and intravascular ultrasound to identify bridging arteries. Surgery called deroofing can be done to free up a compressed artery. Medications may also help symptoms but stents are unlikely to. The podcast highlights this potential new cause of angina symptoms from a rare arterial variation.
