Cross-sectional echocardiographic spectrum of papillary muscle dysfunction. 1979

S Ogawa, and F E Hubbard, and T J Mardelli, and L S Dreifus

Cross-sectional echocardiography identified two abnormal patterns of mitral valve closure in 14 patients with mitral regurgitation due to papillary muscle dysfunction: (1) in three patients with an akinetic inferior-posterior wall but normal cavity size, papillary muscle fibrosis was associated with late systolic mitral valve prolapse, and (2) in nine patients with ventricular dilatation or ventricular aneurysm, the point of mitral valve coaptation was displaced towards the apex of the left ventricle. In two of these patients both abnormalities were observed. In contrast, abnormal patterns were identified in only four of a group of 40 patients without angiographic evidence of mitral regurgitation (10, normal; 27, coronary artery disease; three, congestive cardiomyopathy). Thus, cross-sectional echocardiography can be useful to identify mitral regurgitation secondary to papillary muscle dysfunction.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
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.

D008945	Mitral Valve Prolapse	Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.

D009202	Cardiomyopathies	A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS).
