What is minimally invasive mitral valve repair, performed through right mini-thoracotomy?

Minimally invasive mitral valve repair, or MIMV, goes through a 5 to 7 cm cut between the ribs on the right side. No breastbone gets broken. Repair rates run between 80 and 90 percent at experienced centres, and patients deal with less pain, lower infection risk, and a hospital stay of just 3 to 5 days, much shorter than what a traditional sternotomy puts you through.

According to Dr. Vishal Khullar, Heart Valve Surgeon in Mumbai, Fixing the native valve through a small right-side cut keeps the heart muscle working better than any replacement does, and most people are up and walking inside two days.

Not everyone qualifies. Anatomy decides a lot of this, and so does the actual valve pathology.

• Degenerative valves: Myxomatous degeneration, posterior leaflet prolapse, flail leaflets from snapped chords. Textbook stuff. Repair rates above 95 percent in good hands.
• Younger patients: If you’re trying to avoid blood thinners for life, repair beats replacement, and mini-thoracotomy makes that easier because you’re not laid up for three months recovering from a sternotomy.
• Redo surgery: Anyone who’s had bypass before knows a second sternotomy is risky business, and going in from the right side dodges the old grafts and scar tissue, which is genuinely useful in the right case.
• When it doesn’t fit: Heavy calcification on the mitral annulus, bad peripheral artery disease, or significant aortic regurgitation alongside. Those usually mean conventional sternotomy. That’s a clinical call.

So if you’re trying to weigh things up, our blog on comparing mitral repair versus replacement lays out the long-term picture without the medical jargon.

Two decades in cardiac surgery. Thousands of valve and bypass cases. Dr. Vishal Khullar handles mini-thoracotomy mitral repairs and the redo cases other centres usually pass on, and that’s not a marketing line, it’s just what the case load looks like.

Patients tend to mention the same things. He’s blunt during pre-op. Reviews their echo and CT scans himself instead of handing them to a junior. ICU stays come out shorter than what they were told elsewhere. Small things, but they add up.
