From the experiences with "transseptal left heart catheterization" in 40 patients, this method has been proven to be relatively simple and safty in techniques. Therefore, the procedure can be carried out by any physician trained in the usual techniques of right heart catheterization. As the Brockenbrough method has had advantages over the Ross method in techniques and applications, the author would like to recommend the use of the Brockenbrough method hereafter. In this report, clinical application of this method to dilution method was demonstrated with relation to left atrial pressure. Further application of this method to the hemodynamic study will contribute to clarify the pathologic physiology of the left-sided heart disease.
