Meet Dr. Rajesh Sharma

Dr. Rajesh Sharma is a highly respected and exceptionally skilled doctor who specializes in treating heart problems in children. When a child is born with a heart defect, it is one of the most frightening moments for any parent. Dr. Sharma dedicates his life to fixing these little hearts so that children can grow up healthy, active, and full of life.

Known as one of the busiest and most successful paediatric cardiac surgeons in India, Dr. Rajesh Sharma brings over 32 years of rich medical experience to the operation theater. Throughout his illustrious career, he has successfully performed more than 20,000 cardiac surgeries. His patients range from tiny, premature newborn babies to older teenagers and young adults.

Today, he serves as the Clinical Director of Paediatric Cardiac Surgery at Marengo Asia Hospitals in Faridabad, having previously held top leadership roles at Apollo Hospitals Indraprastha, Fortis Escorts, and Jaypee Hospital. Operating on a baby’s heart—which is often no bigger than a walnut—requires an incredible level of precision, steady hands, and deep medical knowledge. Dr. Sharma possesses all these qualities.

Beyond his surgical brilliance, parents deeply trust Dr. Sharma because of his calm, compassionate, and reassuring nature. He understands the emotional pain of the parents, takes the time to explain the medical condition in very simple words, and treats every child as if they were his own.

Education and Global Training

To become a master in paediatric heart surgery, a doctor must undergo years of rigorous and intense training. Dr. Rajesh Sharma’s educational background is truly world-class, rooted in the finest medical institutions on the globe.

He began his prestigious medical journey in 1982 by completing his M.B.B.S. at the All India Institute of Medical Sciences (AIIMS) in New Delhi, the absolute best medical college in India. Driven by his passion for surgery, he completed his M.S. in General Surgery in 1985, followed by an M.Ch. in Cardiothoracic and Vascular Surgery in 1988, both from AIIMS.

To learn the most advanced and modern techniques in children's heart surgery, Dr. Sharma traveled to the United States. In 1989, he completed a highly specialized Fellowship in Paediatric Cardiovascular Surgery at the Mary Ann Knight Hospital for Children in Miami, Florida.

Following this, he earned the rare and prestigious opportunity to train at the Children’s Hospital affiliated with Harvard Medical School in Boston, Massachusetts. He also received specialized training for Ventricular Assist Devices (VADs) in Berkeley, California. This extraordinary global training allows him to handle the most difficult pediatric heart cases in India today.

Mastery in Complex Congenital Heart Surgeries

"Congenital" means a condition that is present from birth. Many babies are born with structural problems in their hearts. Dr. Rajesh Sharma is a global expert in fixing the most complicated congenital heart defects.

His areas of extreme expertise include:

Transposition of the Great Arteries (d-TGA & CCTGA):
In a normal heart, arteries carry blood to the lungs and the body perfectly. In TGA, the two main arteries leaving the heart are reversed. This is a fatal condition if not treated immediately. Dr. Sharma specializes in complex surgeries to switch these arteries back to their normal position.

Double Switch Operation:
For children born with Congenitally Corrected Transposition of the Great Arteries (CCTGA), Dr. Sharma performs the "Double Switch Operation." This is an incredibly difficult, marathon surgery that only a few surgeons in the world can perform successfully. It restores normal blood flow and allows the child to live a long, healthy life.

Retraining the Regressed Left Ventricle:
Sometimes, the pumping chamber of a child's heart becomes weak. Dr. Sharma uses advanced surgical techniques to "retrain" this chamber, making it strong enough to pump blood properly before doing a final repair.

Avoiding the Fontan Circulation:
Many children born with complex heart disease are put on a single-ventricle pathway (Fontan circulation). Dr. Sharma always tries to avoid this if possible. Instead, he specializes in Biventricular Repair, ensuring that the child's heart functions with two healthy pumping chambers, just like a normal heart.

Advanced Pediatric Heart Failure Treatments

When a child’s heart is failing and cannot pump enough blood, standard surgeries might not be enough. Dr. Sharma provides end-stage failure treatments for children.

• Pediatric ECMO: A life-saving machine that acts as an artificial heart and lungs for a child who is critically ill, giving their real heart time to rest and heal.

• Pediatric LVADs (Left Ventricular Assist Devices): He implants these mechanical pumps to help a weak heart pump blood to the body.

• Neonatal and Pediatric Heart Transplantation: For children whose hearts cannot be saved, he performs complex heart transplant surgeries, giving them a completely new lease on life.

Conditions Treated by Dr. Rajesh Sharma

Dr. Rajesh Sharma diagnoses and cures a massive range of pediatric heart conditions. Parents consult him from all over the world for the following issues:

• Holes in the Heart: Atrial Septal Defect (ASD) and Ventricular Septal Defect (VSD).
• Tetralogy of Fallot (TOF): A combination of four heart defects that causes blue baby syndrome.
• Patent Ductus Arteriosus (PDA): An unclosed hole in the aorta.
• Valve Problems: Aortic Valve Stenosis, Mitral Valve Prolapse, Pulmonary Valve Stenosis, and Tricuspid Valve Disease.
• Coarctation of the Aorta: A narrowing of the major blood vessel carrying blood to the body.
• Heart Rhythm Problems: Tachycardia (abnormally fast heart rate) and Bradycardia (slow heart rate).
• Pulmonary Atresia: A missing or blocked heart valve.
• Congenital Vascular Malformations: Abnormal blood vessels in the heart and chest.

Signs Your Child May Need a Heart Specialist

It is very important to catch heart problems early. You must seek an immediate consultation with Dr. Rajesh Sharma if your baby or child shows any of these signs:

• A bluish tint to the skin, lips, or fingernails (Cyanosis).
• Rapid or very heavy breathing, especially during feeding.
• Poor weight gain and slow physical growth.
• Getting extremely tired or sweating excessively while playing or eating.
• Swelling in the legs, abdomen, or around the eyes.
• Frequent lung infections like pneumonia.

During his years as an Additional Professor at AIIMS and throughout his career, he has mentored and trained a large number of cardiac surgery trainees. Today, many of his students are practicing as independent, successful heart surgeons in various hospitals across India and neighboring countries.

He is also deeply involved in medical research. His primary research focus is finding new and safer surgical treatments for complicated congenital cardiac disorders. He frequently presents his findings at major medical conferences worldwide.
