The distinction is important because the presence of pseudoaneurysm typically requires surgical management.We report the case of a man who presented with monomorphic ventricular tachycardia and was ultimately diagnosed with DCLV. We also review previously reported cases in which patients were incidentally discovered to have DCLV and various imaging studies used to diagnose this condition.
