Dr. Rajesh Kumar. R

Pediatric Cardiologist

Dr. R. Rajesh Kumar is a highly specialised Pediatric Cardiologist at Dr. Mehta’s Hospitals, Chennai, holding FNB (Paediatric Cardiology), the Fellowship of the National Board in Paediatric Cardiology, along with a distinctive Fellowship in Cardiac MRI. This combination of advanced cardiology training and cardiac imaging expertise makes him one of Chennai’s uniquely qualified specialists in the diagnosis and management of heart conditions in children.

His Fellowship in Cardiac MRI is particularly noteworthy. Cardiac MRI (CMR) is an advanced, non-invasive imaging technique that provides unparalleled detail of heart structure, function, and tissue characteristics, and is increasingly indispensable in the evaluation of complex congenital heart disease, cardiomyopathy, and myocarditis in children. Very few paediatric cardiologists in India hold a dedicated fellowship in this subspecialty imaging modality, making Dr. Rajesh Kumar a rare resource for families whose children require the most precise cardiac evaluation available.

For families in Chennai and across South India seeking expert paediatric cardiology consultation, whether for a newborn with a suspected heart defect, a child with heart failure, or a teenager with valvular disease, Dr. R. Rajesh Kumar at Dr. Mehta’s Hospitals offers internationally informed, imaging-enriched cardiac care of the highest standard. Consultations are available by prior appointment.
