Primary percutaneous transluminal coronary angioplasty in the acute infarction of the right ventricle

Abstract

Background. Predilection site for the acute myocardial infarction of the right ventricle, (AMI-RV) is the upper third of the right coronary artery and for this reason such an infarction is followed by numerous complications, primarily by conduction disorders and very often by sudden and rapid cardiogenic shock development. Methods. Primary percutaneous transluminal coronary angioplasty (PPTCA) was performed on three patients in whom the acute infarction of the right ventricular was diagnosed and who had been hospitalized six hours after the beginning of chest pain. In all three patients intracoronary stent was implanted. On the admission patients had been in the threatening cardiogenic shock, with the prominent chest pain and with the elevation of ST-segment in V4R>2 mV. In the course of intervention patients were administered low-molecular intracoronary heparin with direct platelet glycoprotein IIb/IIIa inhibitors (abciximab), according to the established procedure applied in such cases. Results. The complete dilatation of the infarcted artery was established with the signs of reperfusion and the further clinical course was completely normal, there was no heart failure and patients had no subjective difficulties. Conclusion. Invasive approach in the treatment of AMI-RV is justifiable, and possibly the therapy of choice of these patients, providing well trained and equipped team is available.
