Lady Joan Branson likely would have survived had she received preventive blood-thinning medication, a coroner found after examining her fatal pulmonary embolism.
The 80-year-old wife of billionaire Richard Branson died after a deep vein thrombosis sent a blood clot to her lungs and blocked an artery.
Senior Coroner Fiona Wilcox concluded that preventive anticoagulation likely would have saved Branson. The finding puts the focus on why doctors withheld the medication after her hospital admission in November 2025.
Branson, also known as Joan Templeman, entered the hospital weeks after falling on Necker Island in the British Virgin Islands. Immobility after a fracture was among her risk factors for developing a dangerous clot.
Doctors differed over whether bleeding concerns justified withholding enoxaparin, a drug used to prevent blood clots. Hospital admitting doctor Basir Kunduzi testified that he did not complete a bleeding-risk assessment on the day Branson arrived.
Wilcox delivered her conclusion during an inquest at Westminster Coroner’s Court. As Fox News Digital reported, the coroner tied Branson’s death directly to the lack of preventive medication.
“I do find her death would have likely been prevented, and the lack of anticoagulation did cause or contribute to her death probably,”
Wilcox did not classify the case as neglect because Branson received medical care. But that distinction does not erase the central finding: a standard preventive step likely would have changed the outcome.
The inquest also exposed a basic breakdown in the hospital’s process. Without a completed bleeding-risk assessment, doctors lacked a formal review of the danger from giving Branson a blood thinner against the danger from withholding one.
Kunduzi said he would “reflect on [his] role as a doctor” and pointed to the need for “good communication between team members.” Wilcox said the purpose was to “explore the facts, come to the correct conclusions and learn lessons from this.”
Dr. Jared Ross, a South Carolina emergency-medicine physician who did not take part in Branson’s care or the inquest, said nearly all hospitalized adults should receive some form of blood-clot prevention.
“In the vast majority of cases, the benefits outweigh the risks,” Ross said.
Deep vein thrombosis develops when a clot forms in a deep vein. A pulmonary embolism occurs when a clot travels to the lungs and blocks blood flow, creating a medical emergency.
The Centers for Disease Control and Prevention provides guidance on symptoms of deep vein thrombosis and emergency treatment for signs of a pulmonary embolism. The National Heart, Lung, and Blood Institute advises people with pulmonary-embolism symptoms to seek immediate medical attention.
Important questions remain unanswered. The hospital was not identified, and the medical evidence behind the differing views on Branson’s bleeding risk was not detailed. It also remains unclear whether she received any mechanical form of blood-clot prevention.
Richard Branson and Joan Templeman married on Necker Island in 1989. After her death, he paid tribute to the woman he called his “shining star.”
“Life will never be the same without her,” Branson wrote on Instagram.
He also looked back on “fifty incredible years of memories” filled with “tears and laughter, kindness, and a love that shaped our family more than words could ever capture.”
The coroner’s finding leaves a plain lesson: medical judgment requires documented risk checks, clear communication and accountability when a preventable safeguard is missed.
