- 1 What it does: What is the mitral valve? The mitral valve is one of the four valves in your heart.
- 2 Real-world patient consensus: Clinical coding for Mitral Valve Prolapse uses ICD-10 I48.8 across Heart & Vascular specialty care.

What Is Mitral Valve Prolapse?
What is the mitral valve? The mitral valve is one of the four valves in your heart. Heart valves have flaps that open and close. The flaps make sure that blood flows in the right direction through your heart and to the rest of your body. When your heart beats, the flaps open to let blood through. Between heartbeats, they close to stop the blood from flowing backwards. The mitral valve opens to let blood flow from your heart's upper left chamber to the lower left chamber. When the lower left chamber contracts (squeezes) to pump blood to your body, the mitral valve closes tightly to keep any blood from flowing backwards.
Pathophysiology, Underlying Causes & Clinical Presentation
Mechanistic hallmarks of Mitral Valve Prolapse (I48.8) center on fibrotic extracellular matrix in Mitral Valve Prolapse (I48.8: deposition). Cross-referenced with NIH MeSH (Mitral Valve Prolapse), targeted heart & vascular interventions aim to normalize Left Ventricular Ejection in Mitral Valve Prolapse (I48.8: Fraction (LVEF)).
Common Symptoms & Clinical Signs
- • Are older. The risk of MVP increases as aging affects the valve
- • Had rheumatic fever, a disease that can develop after a strep throat infection and cause damage to the heart valves
- • Presentation of Mitral Valve Prolapse (I48.8): reduced exercise tolerance in Mitral Valve Prolapse (I48.8: and premature cardiovascular)
- • Secondary Mitral Valve Prolapse clinical sign: exertional chest pressure in Mitral Valve Prolapse (I48.8: or retrosternal tightness)
