[A case of coronary artery bypass grafting without cardiopulmonary bypass in a patient with left ventricular...

Area of Science:

• Cardiovascular Surgery
• Cardiac Anesthesia
• Interventional Cardiology

Background:

• Severe left ventricular dysfunction poses significant risks for traditional cardiac surgery.
• Myocardial infarction can lead to profound impairment of cardiac output and ejection fraction.
• Minimally invasive surgical techniques are increasingly explored for high-risk cardiac patients.

Observation:

• A 54-year-old male patient with severely reduced left ventricular function (ejection fraction 26%) underwent coronary artery bypass grafting.
• The procedure utilized the left internal thoracic artery for bypass of the left anterior descending artery.
• Surgery was performed with intra-aortic balloon pump (IABP) support, avoiding extracorporeal circulation and cardiac arrest.

Findings:

• The patient was successfully extubated within two hours post-operation.
• The postoperative course was uneventful, with a satisfactory clinical outcome.
• Coronary artery bypass without cardiopulmonary bypass demonstrated safety and efficacy in this patient.

Implications:

• This approach may be a safe and effective alternative for patients with compromised left ventricular function.
• Avoiding extracorporeal circulation and cardiac arrest could reduce surgical stress and complications.
• Further studies are warranted to evaluate this technique in a broader patient population with left ventricular dysfunction.
