3 grafts are blocked diagnosed by angiography
or just by clinical suspicion? pacemaker is adviced for decrease heart rate . i think either CRT OR ICD is adviced by doctor ( ejection fraction
of LV is most probably reduced , or arrhythmia-VT/VF are going on) . these device are very costly.
prognosis depend upon - 1) ejection fraction of LV 2) severity of mitral regurgitation
3) severity of pulmonary hypertension
4) severity of symptoms 5) which arrhythmia are going on 6) associated disease such as hypertension, DM,COPD, kidney dysfunction
discuss in detail with your treating doctor for prognosis
