A 67 year old man had successful thrombolysis for an inferior MI 1 month ago and was discharged after 5days. He is now readmitted with pulmonary edema. What is the most probable diagnosis?

The key is B. Ischaemic mitral regurgitation. [ischaemic mitral regurgitation > raised pulmonary

capillary pressure > pulmonary oedema. Inferior myocardial infarction causes left ventricular

remodeling, which displaces posterior papillary muscle away from its normal position, leading to

ischemic mitral regurgitation].
