Fatality Following Gila Monster Envenomation.

Helodermatid lizard envenomations are rarely reported in the literature, and symptoms are usually mild to moderate, primarily causing pain and localized effects. However, severe toxicity can occur with systemic effects, such as angioedema, hemodynamic instability, and myocardial infarction. Although there are reports of Heloderma bites that are reputedly fatal, the data are inconclusive at best. We report a fatal case following a Gila monster (Heloderma suspectum) bite likely resulting from cascading events initiated at the time of envenomation. This case reinforces the importance of recognizing that envenomated patients may have complex and occasionally idiosyncratic responses to venom and that treatment should be tailored accordingly.
