[Evaluation of coronary lesions in biventricular inferoposterior infarction].

Fifty-two patients with primary transmural infero-posterior infarcts underwent right heart catheterisation on admission to hospital and coronary angiography between the 7th day and 4th month after onset of symptoms. The patients were divided into two groups A (N = 34) with signs of right ventricular dysfunction on admission indicating biventricular infarction, and B (N = 18) without right ventricular dysfunction classified as isolated LV infarction. No significant differences were observed between the two groups with respect to: global and regional LV function; the incidence of single, double and triple vessel disease; the incidence and location of right coronary artery thrombosis; the incidence and location of lesions of the left coronary tree (LCA, LAD, Cx); the extent of coronary disease (Gensini score); the dominant artery (right coronary/circumflex), the frequency and quality of revascularisation of distal vessels.
