MSFinals-0267
A 61-year-old man comes to his General Practitioner complaining of increasing exertional dyspnoea accompanied by bilateral peripheral oedema. He reports feeling extremely fatigued lately. During the physical examination, his lungs are clear, but he has ascites. On auscultation of his heart sounds, you detect a holosystolic murmur with a high pitch at the left sternal edge, extending to the right sternal edge. What is the probable reason for this patient’s symptoms?
