All surgical procedures especially on the heart must be considered major. The heart is vital to a person’s survival as well as quality of life. A cardiac surgeon is uniquely gifted to carry out repairs of the heart, while keeping the heart as well as the rest of the patient alive and well. Coronary bypass doesn’t necessitate opening chambers of the heart, technically this isn’t an open heart surgery and sometimes people think that makes it less major. This is certainly not true, coronary bypass operations must be considered major because a well performed surgery has a direct bearing on the patient.
