What is TAVI/TAVR and Who Needs It?
TAVI (Transcatheter Aortic Valve Implantation), also called TAVR, is a minimally invasive procedure to replace a narrowed aortic valve without opening the chest. A new valve is delivered through a small tube (catheter) inserted through a blood vessel, typically in the groin.
It is the preferred choice for patients with severe aortic stenosis who are elderly, frail, or at high surgical risk where traditional open-heart surgery is too dangerous.
Under Dr. Harikrishnan's expertise, TAVI patients experience faster recovery, less pain, shorter hospital stays, and a dramatic improvement in quality of life, often within days.
- No open-heart surgery required
- Discharge in 3–5 days typically
- Resume normal activities within weeks
- Safe for elderly & high-risk patients
- Minimal blood loss & trauma
TAVI vs. Open-Heart Surgery
| Aspect | TAVI | Open Surgery |
|---|---|---|
| Chest Opening | No | Yes |
| Hospital Stay | 3–5 days | 7–14 days |
| Recovery Time | Weeks | Months |
| Suitable for Elderly | Yes | Higher risk |
| General Anaesthesia | Often avoided | Required |
| Scarring | Minimal | Significant |

Apart from just treating his clients he builds a personal rapport & takes great joy in knowing about the progress of his clients' health.
Best place and doctor for cardiac treatment in Chennai. Best treatment and Dr. Harikrishnan sir explained us every doubt we asked and clarified our health condition to us very well.
He is the only doctor who genuinely wants to reduce the intake of medicines over time rather than just prescribing more. That philosophy gives you so much confidence and trust.
Dr. Harikrishnan spends enough time with his patients, listens carefully and answers every question patiently. He not only prescribes medication but also motivates you to follow a healthy lifestyle. When I started visiting him, I was a different, worried person. I came out a new man.
Dr. Harikrishnan explained everything in a layman's view, replied to our messages on WhatsApp at any time, and guided us through a critical cardiac diagnosis during a very difficult period. His support made all the difference.
After multiple consultations elsewhere, Dr. Harikrishnan finally explained my father's actual problem in detail and helped us avoid an unnecessary procedure. His approach to avoid overtreatment is truly remarkable.
