Coronary Artery Bypass Grafts

Coronary artery bypass surgery is typically performed to treat a blockage or narrowing of one or more of the coronary arteries, in order to restore the blood supply to the heart.

Symptoms of coronary artery disease can include any of the following:

  • Chest pain
  • Fatigue
  • Palpitations
  • Abnormal heart rhythms
  • Shortness of breath

Unfortunately, you may not experience any symptoms of early coronary artery disease, yet the disease will continue to progress until sufficient artery blockage causes symptoms. If the blood supply to the heart continues to decrease as a result of the blockage, a myocardial infarction, or heart attack, may occur. If the blood flow cannot be restored to the affected area of the heart, the tissue dies.

Coronary artery bypass grafts (CABG) will deliver a new source of blood to regions of the heart served by blocked arteries. Surgeons use segments of the patient’s own veins or arteries to go around (or bypass) these blockages. A new, less invasive procedure used by Summa Cardiovascular Institute cardiothoracic surgeons is the off-pump method which eliminates the need for the surgeon to stop the heart and place the patient on bypass. Instead, the surgeon operates directly on the beating heart, reducing the risks often associated with the on-pump procedure. Selection of an on- vs. off-pump procedure by the cardiologist is dependent on the patient’s current health and medical history.

A bypass procedure requires a consultation with a cardiologist. To schedule an appointment or request additional information on Summa's cardiac surgical services, call (888) 926-9540.
