Reassures against attributing ischemic stroke risk to mitral-valve prolapse in young patients; challenges prior reports but leaves open prospective confirmation.
Is mitral-valve prolapse associated with an increased risk of ischemic stroke or transient ischemic attack in young patients?
Using updated echocardiographic criteria, mitral-valve prolapse is not associated with an increased risk of ischemic stroke or TIA in young patients, challenging previous reports.
