Why the study?
Does a mitral prosthesis with resected papillary muscles alter the movement of the mitral annulus compared to normal mitral valves?
Population
15 patients (8 with normal mitral valves and 7 with a mitral prosthesis)
Comparison
Mitral prosthesis vs Normal mitral valves
Design
Cross-sectional

Preservation of papillary muscles may not be required for normal annular motion; leaves open other benefits in prospective valve replacement studies.
Does a mitral prosthesis with resected papillary muscles alter the movement of the mitral annulus compared to normal mitral valves?
The papillary muscles and chordae tendineae may not be essential for the normal movement of the mitral annulus, as their resection during valve replacement does not alter annular motion.
Oakley et al. (1967) studied this question.
