Abstract

Isolated right ventricular infarction is an extremely rare phenomenon which may be difficult to recognize. Also, it is rare to observe ST segment elevation in anterior leads caused by isolated, transient acute marginal branch occlusion. We described the case of a patient suffering Acute coronary syndrome with transient ST segment elevation in precordial leads from V1 to V4, due to isolated right side branch occlusion during right coronary artery stenting.

Introduction

A 60-year-old male patient was admitted to our Hospital with a 1-year history of retrosternal chest pain. The basal ECG showed minimal ST depression in the anterior leads due to an old anterior myocardial infarction 10 years before. Figure 1, in particular, shows sinus rythm and T inverted waves from V1 to V4, suggestive of anteroseptal ischemia. Physical examination was unremarkable. A two-dimensional transthoracic echocardiography (TTE) showed severe hypokinesia of the mid-apical left ventricular wall and normal global righ ventricular (RV) systolic ventricular function (without regional wall motion abnormalities).
