Method for catheter insertion of coronary artery and catheter for its implementation

摘要

What is proposed is a method for the catheterization of the coronary arteries in which a catheter is introduced via the venous system into the right atrium, then passed through the interatrial septum and introduced into the left atrium, followed by the left ventricle, and into the ascending aorta to the opening of the coronary arteries, and also a catheter for the implementation of this method.
