The Duchess International Hospital has achieved a remarkable medical milestone by performing complex open‑heart surgery on “Master D,” a five‑year‑old boy born with Tetralogy of Fallot—a serious congenital defect that disrupts normal blood flow to the lungs. Over three days, from May 19 to 21, 2025, a multidisciplinary team led by Consultant Paediatric Cardiac Surgeon Dr. Mudasiru Salami worked in stages for a combined 14 hours to correct the defect. Under the vigilant care of the Cardiac Intensive Care Unit, Master D has made a striking recovery and has now been moved to the paediatric ward for routine monitoring.
Chief Executive Officer Dr. Adetokunbo Shitta‑Bey explained that, in a healthy heart, deoxygenated blood travels from the right chambers to the lungs to be re‑oxygenated. In Tetralogy of Fallot, however, the defect forces oxygen‑poor blood past the lungs, causing chronic fatigue, cyanosis, and recurrent chest infections. This successful surgery not only restored proper circulation for Master D but also underscores Duchess International Hospital’s commitment to pioneering life‑saving cardiac care.
Master D’s Tetralogy of Fallot comprised four interrelated cardiac malformations: a ventricular septal defect (a hole between the heart’s lower chambers), pulmonary stenosis (narrowing of the valve leading to the lungs), right ventricular hypertrophy (thickening of the right lower chamber from prolonged pressure overload), and an overriding aorta (misalignment allowing oxygen‑poor blood to bypass the lungs). In many advanced healthcare settings, infants born with this complex condition undergo corrective surgery within the first nine months of life to forestall long‑term complications, experts said. Master D, however, did not present until he reached five years of age.

Consultant Paediatric Cardiac Surgeon Dr. Mudasiru Salami described the critical first step of the operation: arresting the heart under cardiopulmonary bypass for five and a half hours—a period fraught with risk. “The first miracle,” he reflected, “was that the heart resumed beating immediately upon reperfusion.” Dr. Salami credited the seamless collaboration of surgeons, perfusionists, anaesthetists, intensivists and nurses, as well as the hospital’s state‑of‑the‑art facilities, for this life‑saving outcome. He also paid tribute to the selfless generosity of Duchess Hospital staff who donated fresh blood when it was most urgently needed. This confluence of skill, technology and compassion exemplifies the multidisciplinary dedication required to conquer congenital heart disease—and to rewrite the future for children like Master D.
Mrs. Olutope Adetona, mother of the miraculous patient, expressed profound gratitude to Duchess International Hospital for saving her youngest son’s life. She confessed that, after watching countless YouTube testimonials from families whose children had undergone similar open‑heart surgeries at Duchess, she felt reassured that her own son was in capable hands. “I begged every parent not to conceal any health challenges,” she urged, her voice steady but emotional. “Speak up early so help can arrive in time.”
Remarkably, the life‑saving expertise that revived Master D comes from a facility barely four years old. Since opening its doors on October 22, 2021, Duchess International Hospital has transformed Nigeria’s medical landscape—marrying cutting‑edge technology with an unwavering commitment to accessible, high‑quality care. Its multidisciplinary teams of surgeons, intensivists, perfusionists, nurses, and allied professionals have worked tirelessly to stem the tide of medical tourism, fostering renewed confidence in home‑grown healthcare.
Their success has not gone unnoticed. Today, an increasing number of Nigerians living abroad are returning to Lagos, drawn by Duchess’s reputation for excellence and compassionate service. In a region where families once felt compelled to seek treatment overseas, Duchess stands as a beacon—its neonatal units, cardiac suites and advanced diagnostic centres all testament to what’s possible when vision, investment and expertise converge.
