[|Human|] My brother, 53 yrs old, had an artificial valve placed after his dr found that he had an enlarged heart. This was in 1998. The last few months, he has had chest pains nearly every day. This wk, the dr told him he had two black spots on his heart & would need to see a heart specialist. He s also on coumadine. The family is very worried, of course. What could this be & is it life-threatening?
[|AI|]  Hello, After going through your medical details I understand your concern and would like to tell you that most likely he is suffering from a heart block which is common in patients with valve replacement. Kindly get an Echocardiography and a Holder (ambulatory ECG)done and consult a Cardiologist for physical evaluation and treatment. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
