Mitral Valve Prolapse (MVP)

Mitral valve prolapse (MVP) is a condition in which the heart's mitral valve doesn't work well. The flaps of the valve are "floppy" and don't close tightly. These flaps normally help seal or open the valve. NIH - National Heart, Lung, and Blood Institute

About Mitral Valve Prolapse (MVP)

Mitral (MI-tral) valve prolapse (MVP) is a condition in which the heart's mitral valve doesn't work well. The flaps of the valve are "floppy" and don't close tightly. These flaps normally help seal or open the valve.

Much of the time, MVP doesn't cause any problems. Rarely, blood can leak the wrong way through the floppy valve. This can lead to palpitations, shortness of breath, chest pain, and other symptoms. (Palpitations are feelings that your heart is skipping a beat, fluttering, or beating too hard or too fast.)

Normal Mitral Valve

The mitral valve controls blood flow between the upper and lower chambers of the left side of the heart. The upper chamber is called the left atrium (AY-tree-um). The lower chamber is called the left ventricle (VEN-trih-kul).

The mitral valve allows blood to flow from the left atrium into the left ventricle, but not back the other way. The heart also has a... Read more about Mitral Valve Prolapse

Evidence reviews

Systematic review of robotic minimally invasive mitral valve surgery

BACKGROUND: Robotic telemanipulators have evolved to assist the challenges of minimally invasive mitral valve surgery (MVS). A systematic review was performed to provide a synopsis of the literature, focusing on clinical outcomes and cost-effectiveness.

Pharmacotherapy in the treatment of mitral regurgitation: a systematic review

BACKGROUND AND AIM OF THE STUDY: Chronic mitral regurgitation (MR) causes volume overload on the left ventricle and, if uncorrected, will over time lead to left ventricular remodeling and heart failure. The benefits of angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs) in primary MR are not well defined.

Prophylaxis Against Infective Endocarditis: Antimicrobial Prophylaxis Against Infective Endocarditis in Adults and Children Undergoing Interventional Procedures [Internet]

Infective endocarditis (IE) is a rare condition with significant morbidity and mortality. It may arise following bacteraemia in a patient with a predisposing cardiac lesion. In an attempt to prevent this disease, over the past 50 years, at-risk patients have been given antibiotic prophylaxis before dental and certain non-dental interventional procedures.
