Peripheral arterial angioplasty balloons as adjuncts to percutaneous coronary revascularization.

Although PTCA balloon technology has improved dramatically since the first catheters were introduced over a decade ago, some limitations remain. The largest conventional balloon size available is 4.0 mm diameter. Larger size balloons are sometimes necessary for saphenous vein graft dilatation or in very large native coronary arteries. Also, adjunctive balloon angioplasty is used frequently after atherectomy and other coronary device therapy. Current generation balloons are not always necessary in this setting, since a large lumen has already been established. Thus, it has become useful in our laboratory to use peripheral arterial angioplasty balloons for both large coronary vessel dilatation, and also for adjunctive dilatation after device use. We describe our initial experience with peripheral arterial angioplasty balloons as adjuncts to percutaneous coronary revascularization.
