A heart condition was identified as the probable cause of death for Eleanor Carol Leavell Barr, wife of Kentucky Rep. Andy Barr, according to preliminary autopsy results.

The condition is known as Mitral Valve Prolapse, or floppy valve syndrome, and occurs when the valve between the heart’s upper and lower left chambers doesn’t close properly, according to the National Heart, lung and blood institute.
