Nondominant right coronary artery occlusion and ventricular tachyarrythmias

Abstract

It is usually considered that occlusion of a nondominant right coronary artery is not associated with significant consequences. We report two cases of nondominant right coronary artery occlusion that presented with sudden cardiac death. Timely intervention resulted in complete resolution of the ventricular arrhythmias. This highlights the need for greater vigilance in the recognition and treatment of these lesions.

Acute Thrombotic Occlusion of Non-Dominant Right Coronary Artery Presenting as Acute Coronary Syndrome and Hemodynamic Instability

“…Moreyra et al reported ST elevation in both anterior and inferior leads [1] . Rao et al reported ST elevation in inferior leads associated with occlusion of NDRCA [2] . Our patient also had ST elevation in inferior leads.…”

“…Moreyra et al reported a case of total occlusion of NDRCA resulting in isolated RV infarction and ventricular fibrillation [1] . Rao et al reported a case of recurrent ventricular fibrillation due to subtotal occlusion on NDRCA [2] . Vural et al reported a case of isolated RV infarction and severe tricuspid regurgitation due to occlusion of nondominant RCA [3] .…”
