Primary PCI for acute myocardial infarction in a patient with situs inversus totalis and dextrocardia

Abstract Situs inversus totalis with dextrocardia is a rare congenital occurrence. Risk of coronary atherosclerosis and acute myocardial infarction in this subset is similar to that in the general population. Diagnosing myocardial injury in time, and executing primary percutaneous coronary intervention (PCI) successfully in these patients is challenging given that physicians are rarely attuned to recognizing the electrocardiographic changes of acute coronary syndromes in this anatomy and interventional cardiologists are not routinely accustomed to working with the angiographic projections in this unique subset. Here, we describe electrocardiogram identification and an approach to primary PCI in one such patient. We have also attempted to simplify and refine primary PCI in this subset by introducing postero-anterior projection single inversion technique for suitable lesions in suitable vessels in this unique subset.
