Most Divers Don't Know They Have This | PFO Risk

Описание: It is the most common heart defect in the world, found in roughly 25% of the population. But for technical divers, a Patent Foramen Ovale (PFO) changes the rules of decompression entirely.

In this deep dive, I am joined by Dr. Mark Turner, a world authority on PFOs and diving medicine. We move past the basic "hole in the heart" explanation to tackle the real data: Why do some studies suggest the risk of Decompression Illness (DCI) can be up to 26 times higher for divers with high-grade PFOs? And more importantly—do you have one?

We discuss the physiology, the real-world risks, and the closure options for divers who want to stay in the water.
