Abstract:
A 30-year-old female with congestive heart failure was referred to our hospital and massive mitral regurgitation was detected on the echocardiography. She was a mother of 2 infants, and wished early recovery from surgery, cosmetic consideration to skin incision and future pregnancy. Her mitral valve was successfully repaired through right thoracotomy with submammary skin incision. Postoperative transthoracic Doppler echocardiography revealed no mitral regurgitation. The patient recovered uneventfully and was discharged on the 8th postoperative day. And she has been drug-free since then.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
