About the Doctor
Dr. Gnanavelu is a senior interventional cardiologist practising on Greams Road, Chennai. His practice covers the full range of cardiac care — emergency angioplasty during a heart attack, imaging-guided stenting for complex blockages, pacemaker and ICD implants, and long-term preventive care.
