Areas of Expertise

Dr Ratan’s practice includes:

• Beating Heart Bypass Surgery: Reroutes blood past blocked arteries while the heart continues pumping naturally without relying on a heart-lung machine.
• Keyhole Valve Replacement: Operates through tiny chest cuts to replace damaged valves with less pain and faster healing.
• Heart Valve Repair: Fixes leaky or faulty valves to help the heart pump blood smoothly in the correct direction.
• Correction of Complex Heart Defects: Rebuilds abnormal heart chambers and connections in infants and children to restore healthy blood circulation.
• Double Artery Bypass: Uses natural chest wall arteries to form durable bypass channels that provide lasting protection against future blocks.
• Heart Failure Care: Treats severely weakened hearts through corrective operations to restore pumping strength.
