In a remarkable medical achievement that underscores the life-saving potential of advanced paediatric cardiac care, MGM Healthcare has successfully performed an extraordinarily complex mitral valve replacement on a 14-year-old girl born with two exceptionally rare disorders—Mesocardia, where the heart lies at the centre of the chest instead of the left, and Morquio syndrome, a rare inherited metabolic disorder that affects the bones, spine and multiple organs. The surgery not only saved the teenager’s life but also highlights the importance of early diagnosis and specialised multidisciplinary care for children with rare congenital conditions.
- MGM Healthcare performs one of India’s most complex paediatric mitral valve replacement surgeries
- Teen battling rare Mesocardia and Morquio syndrome overcomes life-threatening heart disease after hospitals declined surgery
- Open-heart procedure restores normal blood flow, offering hope to children with complex congenital and metabolic disorders
- Multidisciplinary team navigates extraordinary surgical, anaesthetic and anatomical challenges with precision
- Doctors urge early diagnosis and timely intervention for rare cardiac and genetic disorders
- Successful outcome showcases the growing capabilities of advanced paediatric cardiac care in India
The teenager had been suffering from severe mitral regurgitation accompanied by left ventricular outflow tract (LVOT) obstruction, a combination that severely impaired blood circulation, caused extreme breathlessness and left her largely bedridden after forcing her to discontinue her studies.
Several hospitals had reportedly declined to undertake the surgery because of the extraordinary risks posed by the coexistence of the two rare disorders.
The open-heart procedure was successfully led by Dr R.K.R. Noveen Davidson, Senior Consultant, Paediatric Cardiac and Heart & Lung Transplant Surgeon, who navigated the unusual anatomy by making specialised surgical access through the upper chambers of the heart before replacing the diseased mitral valve with a 25-mm mechanical valve and relieving the obstruction that had compromised blood flow.
“It is extremely rare for an individual with Morquio syndrome to have Mesocardia. The girl had developed severe breathlessness because of the obstruction in her left ventricle and had quit her studies because of her condition,” Dr Davidson said.
He explained that valve replacement was the only durable treatment.
“After the surgery, the patient is recovering well. It will take another three to six months for complete recovery,” he added.
The case demanded meticulous planning because Mesocardia significantly altered the heart’s orientation inside the chest, making surgical access far more difficult than in conventional cardiac procedures.
Adding another layer of complexity was Morquio syndrome, a rare genetic metabolic disorder that causes progressive skeletal deformities, cervical spine instability and organ damage. The condition made anaesthesia particularly challenging, requiring continuous protection and stabilisation of the patient’s neck throughout surgery.
Praising the coordinated effort, Dr K.R. Balakrishnan, Chairman – Cardiac Sciences and Director, Institute of Heart and Lung Transplant & Mechanical Circulatory Support, said:
“I am proud of our multidisciplinary surgical and anaesthetic teams successfully completing a highly complex procedure on a child with Morquio syndrome. Our primary focus remains on the patient’s recovery and supporting the family through the next phase of care.”
Highlighting the critical care challenges, Dr Suresh Rao K.G., Co-Director, Institute of Heart and Lung Transplant & Mechanical Circulatory Support, said patients with Morquio syndrome require highly specialised perioperative management.
“Anaesthetic and post-operative management in Morquio syndrome is highly complex due to severe upper airway distortion, cervical spine instability and compromised cardiorespiratory function. This child also had a restrictive lung defect and required close monitoring during the post-operative period,” he said.
Medical experts noted that although Morquio syndrome is rare, delayed diagnosis often results in irreversible skeletal deformities and cardiac complications. Likewise, congenital heart abnormalities such as Mesocardia require lifelong specialist monitoring, making timely medical intervention vital to improving survival and quality of life.
The successful surgery represents a significant milestone in India’s evolving paediatric cardiac care landscape, demonstrating how multidisciplinary expertise, advanced surgical planning and critical care can overcome even the rarest and most complex medical challenges.
