About Dr. Kaul
The senior surgeon other doctors send their difficult cases to
Dr. Ajay Kaul has spent 38 years in cardiac surgery, performing 25,000+ procedures across the full spectrum — from a child’s first heart defect to a third-time redo bypass, including 5,000+ minimally invasive cases. Trained at Bombay University, with fellowships in Germany and Australia, he now leads Cardiac Sciences at Fortis Hospital, Noida.
His approach is stated plainly, not marketed: operate only when it is clearly the right option, use the technique with the best long-term evidence for each patient (including total arterial and beating-heart bypass where suitable), and explain risk honestly — not optimistically.
