Alerts clinicians to possible dual pathology in unexplained syncope; extends HOCM-myxoma associations to non-syndromic cases.
Hypertrophic cardiomyopathy and left atrial myxoma are important cardiac causes of syncope. We present an extremely rare combination of these two diseases in a middle-aged man with syncope. Transthoracic echocardiographic images show the typical features of both conditions. There were no features of progressive cardiomyopathic lentiginosis (LEOPARD syndrome) which is known to be associated with both the conditions.
