Modern cardiac surgery has transformed outcomes for patients with heart disease. Explore the advanced, minimally invasive techniques used at Iswarya Hospital, OMR Chennai.

Modern cardiac surgery has revolutionised the treatment of heart disease. Advanced techniques designed to be effective and minimally invasive now allow patients to recover faster, return home sooner, and resume normal life with greater confidence. At Iswarya Hospital in OMR, Chennai, our cardiothoracic team offers the full spectrum of modern heart surgery options.

When Is Heart Surgery Needed?

Heart surgery may be recommended for:

Coronary artery disease (blocked arteries not responding to angioplasty)

Valvular heart disease (damaged or diseased heart valves)

Heart failure requiring structural repair

Congenital heart defects

Aortic aneurysm or dissection

Arrhythmias requiring surgical ablation

Modern Heart Surgery Techniques at Iswarya Hospital

1. Coronary Artery Bypass Grafting (CABG)

CABG restores blood flow to the heart by creating new routes around blocked arteries using blood vessels taken from the leg, arm, or chest.

At Iswarya Hospital, we perform:

Off-pump (beating heart) CABG: Surgery on a beating heart without the heart-lung machine — reduced risk of stroke and kidney complications

Minimally invasive CABG (MICAB): Small incisions, less pain, faster recovery

Robotic-assisted CABG: Ultra-precise surgery with minimal trauma

2. Heart Valve Repair and Replacement

Damaged valves can be repaired (preferred) or replaced with mechanical or biological prostheses.

Modern approaches include:

Minimally invasive valve surgery: Small incisions instead of full sternotomy

TAVR (Transcatheter Aortic Valve Replacement): Replacing the aortic valve via a catheter — no open-heart surgery required, ideal for high-risk patients

MitraClip: A catheter-based clip to repair mitral valve regurgitation

3. Ventricular Assist Devices (VAD)

For patients with severe heart failure, VADs mechanically support the heart while waiting for transplant or as long-term therapy.

4. Aortic Surgery

Treatment for aneurysms (bulges) or dissections in the aorta:

Open repair: Replacing the affected aorta section with a graft

Endovascular repair (EVAR/TEVAR): Stent-graft placement via catheter — much less invasive than open surgery

5. Surgical Treatment of Arrhythmias

Maze procedure: Creates scar tissue in a pattern that blocks the electrical signals causing atrial fibrillation

Combined with other cardiac surgery for maximum benefit
