A Non-ischemic Spontaneous Papillary Muscle Rupture. Case Report
We report a case of spontaneous mechanical papillary muscle rupture
(PMR). We believe that the etiology of PMR, in this case, is related to
a histological damage of the valve, extreme sudden force to the
papillary muscle, and some possible tissue hypo-perfusion of the
subvalvular apparatus. We performed a mitral valve replacement and
bypass coronary surgery with good results.
