Castle Hill Hospital Police Investigation – A Tragic Reminder Why Medical Transparency Matters

Recent reports by the BBC have highlighted concerns regarding the safety and governance of the TAVI (Transcatheter Aortic Valve Implant) service at Castle Hill Hospital near Hull.

According to investigative reporting, 11 patients died following TAVI procedures carried out at the hospital between 2019 and 2023. Several of these deaths are now under police investigation, after internal documents and independent reviews suggested that patients may have suffered avoidable harm and, crucially, that death certificates did not accurately reflect the role these procedures played in the patients’ deaths.

What Is TAVI?

TAVI is a minimally invasive alternative to open-heart surgery, typically offered to older patients considered high-risk for more invasive procedures. The operation, often carried out under local anaesthetic, involves replacing a damaged heart valve using a catheter inserted through the groin. It is meant to be safe, with UK-wide mortality rates relatively low.

However, Castle Hill’s TAVI mortality rate was found to be three times the national average during the period under review.

A Catalogue of Errors and Missed Warnings

One of the most disturbing stories is that of Dorothy Readhead, an 87-year-old patient whose TAVI procedure went catastrophically wrong. Despite pre-operative plans to access the heart via her left artery—due to blockages in the right—the procedure was mistakenly initiated on the wrong side. This led to catastrophic bleeding and complications, resulting in Mrs Readhead losing five litres of blood and enduring a six-hour procedure while fully awake.

Worryingly, her death certificate made no mention of the procedure or the complications. It cited pneumonia and heart disease. Her family only learned the full extent of what occurred when contacted by the BBC.

Independent reviews conducted by the Royal College of Physicians (RCP) and external consultants uncovered:

• Poor clinical decision-making, including use of inappropriate access sites

• Repeated procedural failures during surgery

• Evidence that critical complications were omitted from patient death certificates

• Lack of transparency with families

• Ignored warnings from medical device manufacturers

Internal Whistleblowing and Institutional Denial

In 2021, seven cardiac consultants wrote a letter to the hospital’s chief executive, raising concerns about patient safety and the lack of transparency. One senior clinician who flagged these issues internally—Dr. Thanjavur Bragadeesh—was later asked to step down from his leadership role in what appears to have been part of a wider reorganisation. He later took the trust to an employment tribunal.

Despite repeated reviews, and the damning conclusions they reached, there is still concern that the hospital failed to take timely and meaningful action. Most alarmingly, families were not informed that reviews had taken place, nor were they made aware of the findings—until now.

Legal and Ethical Implications

This is a clear example of the intersection between medical negligence and lack of institutional accountability. When patients suffer avoidable harm, there must be transparency, appropriate reporting, and communication with families.

The apparent failure to:

• follow device manufacturer warnings

• declare serious incidents promptly

• report complications accurately to coroners

• inform families of reviews and complications

These failures raise serious legal and ethical questions about the standard of care delivered, and whether trust policies, national reporting duties, and GMC guidelines have been breached.

As specialists in medical negligence, we believe that patients and their families deserve honesty and accountability. This tragic situation underscores the importance of:

• Independent investigation of clinical failings

• Accurate death certification and coroner referrals

• Proper informed consent

• Institutional openness and learning
