Absence of special programs for quantitative analysis of right ventricular volumes and function precludes precise evaluation of right ventriculography data. We used standard programs designed for analysis of left ventriculograms for evaluation of right ventricular volumes and function in 32 patients without and 20 patients with coronary artery disease. Left ventriculography and right atriography were carried out in 30- and 60-degree right and left anterior oblique projections, respectively. Average correction factors obtained by comparison of left and right ventricular stroke volumes were 0.9243+/-0.2887 and 0.8758+/-0.2232 for patients without and with coronary artery disease, respectively. Such conversion was considered to be simple and adequate method of adaptation of existing programs of quantitative analysis of angiograms for evaluation of right ventricular volumes and function.
