Care, Personalized for You
Using state-of-the-art catheter-based approaches, Dr. Sengottuvelu treats heart valve issues with minimal risk and quicker recovery.
Valve Disorders – Treated Without Open Surgery:
TAVI/TAVR (Transcatheter Aortic Valve Replacement), TMVR (Transcatheter Mitral Valve Replacement), TEER (Transcatheter Edge-to-Edge Repair using MitraClip/MyClip for mitral or tricuspid valve regurgitation), and TTVR (Transcatheter Tricuspid Valve Replacement) are modern alternatives to traditional open-heart surgery. These procedures significantly reduce surgical risks and support faster healing.
Coronary Artery Disease – Narrowing or Blockages:
Dr. Sengottuvelu treats narrowed or blocked arteries with high precision. He performs angioplasty and stenting for both simple and complex cases, including Primary PCI (emergency angioplasty for heart attacks), left main and bifurcation stenting. He also uses drug-eluting stents, bioabsorbable scaffolds, and critical support devices like Impella — a mechanical heart pump for high-risk patients.
Calcium in Blood Vessels – Advanced Removal Tools:
For hardened, calcified arteries, advanced tools such as rotational atherectomy, orbital atherectomy, intravascular lithotripsy (IVL), and laser therapy are used to safely restore blood flow.
Precision Diagnostics – Visualizing Inside the Arteries:
Technologies like OCT (Optical Coherence Tomography), IVUS (Intravascular Ultrasound), and FFR (Fractional Flow Reserve) allow high-resolution visualization and detailed assessment of blood vessels from within, enabling accurate, tailored treatments.
Overall, Dr. Sengottuvelu delivers targeted heart care with a focus on efficacy, safety, and early recovery.
