Abstract:
Right ventricular (RV) infarction is commonly associated with left ventricular (LV) myocardial infarction. Isolated RV infarction is a rare entity and the diagnosis is challenging. We present a case of a 65-year-old man with non-ST elevation myocardial infarction without obvious culprit obstructive coronary artery disease on coronary angiogram. There was late gadolinium enhancement (LGE) of RV free wall without LGE of the LV in magnetic resonance imaging (MRI) which helped in diagnosing isolated RV infarction. On follow up, the patient's RV dysfunction normalized on echocardiogram. Our case shows the importance of cardiac MRI in the diagnosis of isolated RV infarction and that it can have a good prognosis.
Learning Objectives:
Diagnosis of isolated right ventricular (RV) infarction needs high degree of suspicion especially in absence of hemodynamic findings. Late gadolinium enhancement in cardiac magnetic resonance imaging can help diagnose RV infarction when there is diagnostic uncertainty. Early therapy helps in RV recovery.
