Mitral regurgitation, caused by a leaky heart valve, happens when the valve between your heart’s lower left chamber (ventricle) allows blood to flow back into the upper chamber (atrium) with each heartbeat. Over time, the extra burden on your heart and lungs can enlarge and weaken your heart and may lead to congestive heart failure.
If you aren’t a good candidate for open heart surgery and your valve needs to be more than repaired, your doctor may suggest replacing your mitral valve with this minimally invasive procedure.
