A 62-year-old woman with hypertrophic obstructive cardiomyopathy suffered from repeated heart failure. Preoperative echocardiogrphy demonstrated pressure gradient (PG) of 64 mmHg in left ventricular cavity, mitral regurgitation II, and tricuspid regurgitation II with an ejection fraction of 74%. Cardiac catheterizaition revealed cardiac index of 1.50 l/min/m2. She was recommended mitral valve replacement (MVR) because she was hospitalized several times for heart failure. She underwent MVR, tricuspid annuloplasty, and modified maze operation. Postoperative PG fell till 15 mmHg in echocardiogrphy. Postoperative cardiac catheterization revealed cardiac index of 2.00 l/min/m2. MVR contributed to decrease of PG in intraventricular cavity and increase of cardiac output. Postoperative cardiac status was classified as New York Heart Association (NYHA) class I-II.

D008944 Mitral Valve Insufficiency Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.

D002312 Cardiomyopathy, Hypertrophic A form of CARDIAC MUSCLE disease, characterized by left and/or right ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR; HYPERTROPHY, RIGHT VENTRICULAR), frequent asymmetrical involvement of the HEART SEPTUM, and normal or reduced left ventricular volume. Risk factors include HYPERTENSION; AORTIC STENOSIS; and gene MUTATION; (FAMILIAL HYPERTROPHIC CARDIOMYOPATHY).

D006333 Heart Failure A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
