The patient was ultimately found to have intermittent severe aortic insufficiency. Upon surgical exploration abnormalities were discovered in the aortic valve which had a small left coronary cusp with absence of the nodulus of Arantius. Following surgical repair of the valve aimed at preventing the small cusp from becoming stuck in the open position the patient has remained episode free for over one year. Background Apparent life threatening events ALTEs characterized by a combination of apnea decreased muscle tone and color change remain a challenge for general and subspecialty pediatricians. The possibility of sudden infant death syndrome SIDS though not necessarily related to ALTEs leads to an extensive work-up for these events. In the approximately 50 of ALTE work-ups that do reveal a diagnosis 98 of these have gastrointestinal neurologic or respiratory etiologies 1 . However in part because of the large number of idiopathic ALTEs cardiologists are frequently consulted in these cases when the reflux and neurologic work-ups are unrevealing. The commonly accepted cardiac causes are limited to arrhythmias cardiomyopathies and structural disease most of which can be diagnosed by echocardiogram or EKG monitoring. We present a case of lifethreatening events caused by intermittent aortic insufficiency and a surgical solution to these events. Case Presentation CV was a term infant who presented to another hospital at 5 weeks of age following an episode of .
