Cicatricial changes in a Ionescu-Shiley bioprosthesis. 1994

V M Walley, and W A Stinson, and P Bedard

Department of Laboratory Medicine, Ottawa Civic Hospital, Canada.

The mitral Ionescu-Shiley standard-profile prosthesis of a 53-year-old woman who had it placed 12 years previously is described. The observed cicatricial retraction of one of the bioprosthesis' cusps is unusual, and it contributed to the bioprosthetic dysfunction which necessitated this valve's replacement.

UI	MeSH Term	Description	Entries
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D008943	Mitral Valve	The valve between the left atrium and left ventricle of the heart.	Bicuspid Valve,Bicuspid Valves,Mitral Valves,Valve, Bicuspid,Valve, Mitral,Valves, Bicuspid,Valves, Mitral
D008946	Mitral Valve Stenosis	Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.

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).
