The merits of the bypass surgery to cure heart problems were discussed at a major cardiology conference. During the conference, the American College of Cardiology raised questions about the capability of the surgery.

Bypass surgery is the most common method of treating people with left main coronary artery disease. Narrowing of the arteries is the major cause of heart attacks among people. In this surgery, vessels are taken from a patient's arm or leg and sewn on the heart to replace clogged ones.

Doctors have also suggested angioplasty for heart surgery because the technique is less invasive than bypass surgery but can require more repeat procedures if the artery restricts again over the time.

To evaluate the impact of two surgeries on heart patients a study was conducted on 600 patients. Half of the patients received angioplasty and other half received bypass surgery. The findings unveiled that the survival rate was similar among the two groups. Death, heart attack and stroke rates were also similar among these people but 9% of the patients in angioplasty group experienced ischemia-driven TVR after two years whereas only 4.2% patients on the bypass group experienced the same.
