Coroner Rules Lady Joan Branson's Death Potentially Preventable
A British coroner determined that Lady Joan Branson's death from a pulmonary embolism could likely have been prevented with timely blood-thinning medication.
Lady Joan Branson, wife of Virgin Group founder Sir Richard Branson, died at age 80 from a pulmonary embolism caused by deep vein thrombosis (DVT), a condition that a British coroner found could likely have been prevented with the administration of anticoagulants. The conclusion came after an inquest into her death, which occurred in November 2025 following a fall weeks earlier on Necker Island.
Senior coroner Fiona Wilcox stated at Westminster Coroner's Court that Lady Branson did not receive preventive anticoagulants, commonly known as blood thinners, despite having a "very high risk of developing deep vein thrombosis." Wilcox noted that the lack of anticoagulation "did cause or contribute to her death probably." The inquest heard that Lady Branson's immobility after a fracture following her fall was a significant risk factor for DVT.
However, Wilcox clarified that the case was not one of neglect, as Lady Branson had received medical care. The purpose of the inquest, she said, was to "explore the facts, come to the correct conclusions and learn lessons from this."
During the inquest, medical professionals presented differing testimony regarding whether the risk of bleeding justified withholding enoxaparin, an injectable blood thinner. The hospital's admitting doctor, Dr. Basir Kunduzi, testified that he did not complete a bleeding risk assessment on the day of Lady Branson's admission. He added that her death prompted him to reflect on his role and the importance of "good communication between team members."
Doctors explained that blood thinners are crucial in hospitals to prevent DVT in patients with limited mobility due to surgery, fractures, or prolonged bed rest. While they can increase bleeding risks, doctors must balance these against the potential for DVT. Dr. Jared Ross, an emergency medicine physician not involved in the case, commented that for nearly all hospitalized adults, some form of clot prevention, whether medication or mechanical devices, should be administered, as the benefits typically outweigh the risks.
A pulmonary embolism occurs when a blood clot travels to the lungs, blocking an artery. Symptoms can include shortness of breath, chest pain, rapid heartbeat, coughing up blood, and lightheadedness. The Centers for Disease Control and Prevention advises seeking immediate medical attention for anyone experiencing these symptoms.
A spokeswoman for Sir Richard Branson stated that the family does not plan to comment on the inquest, directing inquiries to Sir Richard's past social media posts honoring his wife. In a previous Instagram post, Branson described his late wife as the "shining star" of their family and reflected on their 50 years together, filled with "tears and laughter, kindness, and a love that shaped our family."
