Angioplasty of unusually large coronary arteries using the hugging balloon technique via a single guiding catheter.
Unusually large native coronary arteries, in particular those supplying expansive regions of myocardium, may not be adequately dilated using currently available coronary angioplasty catheters. The "hugging balloon" technique, in which two dilatation catheter balloons are simultaneously inflated side-by-side, has been previously described for lesions in large saphenous vein grafts using the double guiding catheter (and dual entry site) technique. With the development of large lumen guiding catheters and lower profile dilatation catheters, we report the initial use of the hugging balloon technique via a single guiding catheter in oversized native coronary arteries.
