Malignant Mimicry: An Unusual Cause of VT and AV Conduction Disease

“…The clinical profile of myocardial involvement by metastatic disease remains poorly defined and, like our case, may mimic more common pathology upon clinical presentation. Badri et al recently described a similar patient with a history of lung cancer who presented with MMVT and was noted to have biopsy-proven squamous cell carcinoma of an unknown primary metastatic to the RV [4]. In our case, we felt that a presentation of sustained VT and asymmetric LVH in a middle-aged patient with no personal or family history of cardiac disease and no previous cardiac symptoms whatsoever warranted further evalu- ation prior to presumptively diagnosing the patient with HCM.…”
