How Is a Left Ventricular Aneurysm Repaired?

A left ventricular aneurysm is basically a thinned-out, scarred bulge in the heart’s main pumping chamber. It’s usually what’s left behind after a major heart attack. Fixing it means open-heart surgery, cutting away or reshaping that weak, ballooned patch of muscle. The goal is to restore a shape the heart can actually pump with. It’s major surgery, and it’s usually not done alone. Bypass grafting is often performed alongside the repair.

According to Dr. Vishal Khullar, a leading Cardiothoracic Surgeon in Mumbai, “People hear the word aneurysm and understandably worry. But a stable aneurysm under close monitoring isn’t automatically an emergency. Symptoms, heart failure, arrhythmias, or clot risk are what genuinely tip the decision toward surgery.”

Surgeons choose between a few techniques here, and the decision comes down to the aneurysm’s size and exact location.

• Linear closure: Surgeons trim away the thinned, scarred segment and sew the edges shut directly. This technique still works well for smaller aneurysms.
• Dor procedure, endoventricular patch repair: For bigger apical aneurysms, a patch rebuilds a chamber shape closer to normal, rather than simply closing an opening.
• Concomitant bypass grafting: Blocked arteries get bypassed in the very same operation. Leave them untreated, and survival drops on its own, regardless of the aneurysm repair.
• Echo-guided planning: Every repair starts with echo and often cardiac MRI, mapping exactly how much muscle is viable before anyone decides on a technique.

Recovery after this kind of open-heart repair tracks closely with what we covered in valve surgery recovery.

Dr. Vishal Khullar holds an MBBS, MS, and MCh, along with fellowship training in advanced cardiovascular surgery from Cleveland Clinic and Mayo Clinic. He has more than 30 years of experience and has performed over 7,000 heart surgeries, including complex combined bypass and ventricular reconstruction procedures for exactly this condition. Rather than defaulting to one technique, he selects between linear closure, patch reconstruction, and the Dor procedure based on each patient’s anatomy and heart function.
