A probe having the ability to deliver cardioplegia solution to the coronary sinus under direct visualization and to provide venous drainage from the right atrium for cardiopulmonary bypass. The probe has an elongate tubular member, including a distal end, a proximal end, and a lumen. A membrane, optionally perforated, mounted within the lumen of the tubular member partitions the lumen and is removable or penetrable by a cardioplegia catheter. The distal end comprises a toroidal balloon or a circumferential recessed vacuum manifold. A vacuum port communicates with the distal end of the tubular member or the vacuum manifold. Methods of using the cardioplegia access view probe for catheterization of the coronary sinus and for venous return as herein described are also disclosed.
