What Is Hidden Behind Inferior Negative T Waves

Abstract

Negative T waves in the inferior leads in an asymptomatic 17-year-old female patient prompted a diagnostic evaluation disclosing the presence of multiple cardiac glomangiomas. The combination of different imaging modalities (echocardiography, magnetic resonance, and positron emission tomography/computed tomography) and myocardial biopsy was crucial to establishing the correct diagnosis. ( Level of Difficulty: Advanced. )

Excision of a rare cardiac tumor aided by endocardial electroanatomical mapping

“…Similar to our case, three of the tumors presented with electrocardiogram changes. One case in a 17‐year old presented with similar T‐wave changes to our case 2 . However, this case was treated medically following biopsy, due to the tumor not being resectable.…”

“…3 To date, there have only been six reported cases of glomus tumors affecting the heart. 2 Two-thirds were benign with the remaining two patients having malignant tumors. Similar to our case, three of the tumors presented with electrocardiogram changes.…”

“…Commonly they present as dermal tumors. Glomus tumors makeup 2% of soft tissue tumors, 1 but are rarely found in the heart 2 . We report a case of an adult male with a history of multiple glomangiomas who underwent excision of two cardiac glomus tumors using a novel technique to map out the tumor margins interoperatively.…”
