Kerala government hospital doctors seal leaking artificial heart valve without open surgery

Doctors at the Government Medical College Hospital in Thiruvananthapuram have treated a leak around an artificial heart valve in a 55-year-old woman using a minimally invasive catheter-based procedure, officials said on Friday. The approach avoided the need for a second open-heart surgery.

State Health Minister K. Muraleedharan said in a statement that the procedure was performed jointly by the hospital's cardiology, anaesthesia and cardiothoracic departments.

The woman had earlier undergone surgery for severe heart disease, during which her mitral and aortic valves were replaced with artificial metal valves. Patients with mechanical valves generally require lifelong blood-thinning medication and regular monitoring. In her case, a leak subsequently developed near the mitral valve.

Such leaks, known medically as paravalvular leaks, are a known complication after valve replacement surgery. They are usually corrected through complex surgery that involves opening the chest — a demanding option for a patient who has already undergone one major heart operation.

To avoid that, the team chose a catheter-based technique. A thin tube, or catheter, was inserted into the heart through the femoral vein in the leg, and a specialised plug was used to seal the leak. According to the Minister, the method avoided an open-chest operation and the associated incisions and stitches, while reducing post-operative complications. He said the patient's condition was satisfactory and that she was expected to be discharged soon.

Dr. Mathew Iype, head of the cardiology department, described the procedure as technically challenging and rare in a patient with two artificial heart valves. He said the case reflected the growing capabilities of government medical colleges in Kerala.

Doctors note that catheter-based closure is not an option for every patient. Whether it can be used depends on the size, shape and position of the leak, the condition of the surrounding tissue and the patient's overall health. In many cases, open surgery remains the standard treatment.

The Minister's statement did not include further clinical details about the patient, such as how long she had lived with the leak or how she will be followed up. The Minister congratulated the healthcare professionals involved in the procedure.

The case illustrates both the possibilities and the limits of minimally invasive heart care. Such procedures can spare patients the trauma of repeated open-heart surgery, but they require specialised equipment, trained multi-disciplinary teams and careful patient selection, and are generally available only at well-equipped centres.

Kerala's government medical colleges have reported a growing number of complex cardiac procedures in recent years. For patients, the immediate significance of this case is specific rather than sweeping: one woman whose leaking valve was sealed without her chest being opened again, and who, according to the Health Minister, is recovering well.
