He is thin, has a bulging praecordium and a prominent apical impulse. He is not cyanosed or clubbed. He has a pansystolic murmur and a high-pitched early diastolic murmur at the left sternal edge. His chest x-ray shows cardiomegaly without plethora. His blood count and inflammatory markers are normal. What complication of his original lesion best explains his heart failure?
