1. A method of treating ischemic heart disease by providing long-term retrograde transvenous myocardial perfusion, the method comprising steps of:

  • creating a conduit between a patient'"'"'s left ventricle and coronary sinus, so that blood flows through the conduit from the left ventricle to the coronary sinus during cardiac systole;

    partially occluding the patient'"'"'s coronary ostium; and

    limiting a peak pressure attained within the coronary sinus by venting blood received from the left ventricle into the patient'"'"'s right atrium when the pressure attained within the coronary sinus exceeds a predetermined value.
