0 relating to a papilla (= a small, round raised structure at the base of hair or teeth or on the tongue) --
When mitral regurgitation is due to dysfunction of the papillary muscles, however, results of repair are not always good.
The opening of the ventricular septal defect was immediately above the medial papillary muscle of the tricuspid valve.
Necropsy showed a grossly abnormal arrangement of ventricular myocardial fascicles and bands, with absence of the papillary muscles causing tricuspid and mitral regurgitation.
It was not attached to the leaflets of the mitral valve, which were supported by two separate papillary muscles.
A ventricular septal defect and rupture of the papillary muscle were found.
The papillary muscles in their case, however, were normal.
Both papillary muscles were hypertrophied, and the atrioventricular junction was dilated.
A small papillary muscle was attached to the underside of the imperforate valve.
