Abstract
Initial experience with the technique of “kissing balloon” angioplasty is described in 52 patients undergoing coronary angioplasty. Guiding catheters employing both the femoral and brachial approach were used in all but two of the coronary angioplasties and, in addition, the bilateral femoral approach was used in the renal and peripheral angioplasties. Initial success was achieved in 51 (98%) patients. Abrupt closure requiring urgent coronary revascularization occurred in one patient six hours following the completion of the procedure. Another patient developed a new Q‐wave on the electrocardiogram and moderate elevation of CPK‐MB fraction following the procedure due to loss of a diagonal branch. No deaths occurred in this series. Angiographic restenosis developed in ten patients. In the recurrence group, five had repeat kissing balloon angioplasty, two had repeat single vessel angioplasty, and three patients chose elective surgical revascularization. Based on our experience, the technique of kissing balloon coronary angioplasty can be performed safely utilizing the brachio‐femoral technique. The risk of major side branch occlusion can be minimized with this technique and the overall complication rate does not significantly differ from that of our experience in single vessel coronary angioplasty. Patient selection criteria are based upon the angiographic relationship of the major branch to the side branch and is important in determining the initial and long‐term success of this technique.
