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.

Podcast Summary

Introduction

Dr. Warrick Bishop is a practicing cardiologist and author dedicated to improving patient care through heart health education. In this episode, he explores the four main valves of the heart and discusses cutting-edge technological advances—particularly percutaneous and transcatheter techniques—that are revolutionizing how valve problems are treated without major surgery. The focus is on emerging non-invasive approaches for aortic, mitral, and tricuspid valve issues and their growing role in modern cardiology.

Key Takeaways:

• The heart has four main valves (tricuspid, pulmonary, mitral, and aortic) that control blood flow and can deteriorate over time, causing leaking or narrowing.

• Aortic valve narrowing affects approximately 1% of the population and becomes increasingly common with age, making non-invasive treatment options increasingly valuable.

• Transcatheter aortic valve implantation (TAVI) allows deployment of new valves through blood vessels in the leg, avoiding major chest surgery and becoming standard practice for high-risk and intermediate-risk patients.

• Transcatheter edge-to-edge repair for leaking mitral valves is available but currently less advanced than aortic technology, with higher mortality rates (4% at 30 days) and is typically reserved for very high-risk surgical candidates.

• Tricuspid valve repair using percutaneous transcatheter techniques shows the most promise because the lower-pressure right heart system allows devices to work more effectively with less strain.

• Early intervention with transcatheter tricuspid repair can prevent severe regurgitation that leads to dangerous organ congestion and extremely high mortality rates in advanced stages.

• Regular echocardiogram screening and baseline heart imaging are essential preventative measures to detect valve problems early before they progress.

• Blood pressure control is critical for valve health, as elevated pressure increases wear and tear on valves and should be monitored with a 24-hour blood pressure monitor.

• Patients should maintain regular check-ups with their GP and consider consulting a cardiologist for preventative care and baseline cardiac imaging.
