Mitral Valve Prolapse I: Introduction

Mitral Valve Prolapse I: Introduction

IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow.

It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
