People having surgery to repair tight or leaking heart valves may receive a pacemaker more often than necessary—leading to a greater risk for life-threatening complications, studies show. It's common for a patient with a leaking mitral valve to have the same issue in the tricuspid valve. Not repairing the leaks, often referred to as regurgitation, can cause heart failure.
In a 2021 national study published in The New England Journal of Medicine , patients who had the two valve issues corrected in one surgery were less likely to experience worsening tricuspid valve disease. However, when both valves were fixed, 14% of patients in the trial required a pacemaker , which regulates the heart's rhythm. Similar results were reported by the Society of Thoracic Surgeons in 2017.
"Needing a pacemaker after heart surgery is not benign and can put the patients at risk for late complications, including heart failure ," said Gorav Ailawadi, M.D, M.B.
A., chair of the Department of Cardiac Surgery at U-M Health and a co-director of the U-M Health Frankel Cardiovascular Center. "We were shocked about these reports and were interested in examining our experience at a high volume hospital with one of the largest experiences of mitral valve surgery.
" The research team at the Frankel Cardiovascular Center reviewed nearly 1,500 cases of patients receiving simultaneous mitral valve surgery and tricuspid valve repair between 2011 and 2021. Patients who had operations performed by surgeons with mit.
