Rare cardiopulmonary complications of chronically decompensated myasthenia gravis.
Although myasthenia gravis (MG) is frequently mentioned in standard textbooks and journal articles as a rare cause for pulmonary hypertension and right heart failure, no case can actually be found in the literature. The case described in this report is the first documented case of chronically decompensated MG manifesting itself as pulmonary hypertension, severe right heart failure, and functional prolapse of both the mitral and tricuspid valves. Interestingly, no hepatic biochemical abnormalities were present in spite of significant congestive hepatomegaly.
