Key result
A young woman with arrhythmic mitral valve prolapse sustained sudden cardiac arrest and died from an opportunistic infection, highlighting the need for awareness of risk factors for sudden death.
Why the study?
It is not known which risk factors for sudden death in MVP should be weighed more heavily, and there is no consensus on which patients benefit from a primary prevention defibrillator.

Case suggests arrhythmic mitral valve prolapse may confer sudden death risk; leaves open validated stratification before practice change.
Mitral valve prolapse (MVP) is present in 2-3% of the general population. A small percentage of these patients develop sudden cardiac death. Although there have been several clinical, EKG, and imaging findings associated with sudden death in MVP patients, it is not yet known which of the risk factors should be weighed more heavily than other. More importantly, there is no consensus on which patients might benefit from a primary prevention defibrillator. We present a case of a young woman who sustained sudden cardiac arrest, and began recovering after a prolonged resuscitative effort. She ultimately succumbed to opportunistic infection. In hindsight, she had many of the concerning findings of arrhythmic mitral valve prolapse. Raising awareness of this condition can help to reduce risk of sudden death in these patients.
