ABSTRACT:
A process for inducing cardioplegicarrest of a heart in situ in a patient's body, comprising maintaining the patient's systemic circulation by peripheral cardiopulmonary by-pass, occluding the ascending aorta through a percutaneously placed arterial balloon catheter, venting the left side of the heart, and introducing a cardioplegic agent into the coronary circulation. This procedure readies the heart for a variety of surgical procedures that can be performed percutaneously through lumina in the catheter. An aortic catheter for use in the process is also described.
