Indications for Coronary Artery Bypass Grafting (CABG)
Left main artery disease or equivalent
Triple vessel disease
Abnormal Left Ventricular function.
Immediately after Myocardial Infarction (to help perfusion of the viable myocardium).
Life threatening arrhythmias caused by a previous myocardial infarction.
Occlusion of grafts from previous CABGs.
Bypass grafting may be contraindicated in patients, for e.g. absent viable myocardium or the artery that needs grafting is too small.
An Argentinean cardiac surgeon called Rene Favaloro in 1960's first pioneered CABG and today over 500,000 CABGs are done every year in United States alone. In India where there is a rising incidence of heart disease the number of CABG surgeries is showing an increasing trend.
