Simultaneous transradial coronary angioplasty and contralateral coronary angiography with a single guide catheter for total coronary occlusions.

OBJECTIVE In order to prevent double arterial access for contralateral angiography for percutaneous coronary intervention (PCI) of occluded coronary arteries, a new technique is under development, requiring only one puncture site and one guide catheter (1P1G). BACKGROUND Percutaneous intervention for coronary artery occlusions frequently requires visualization of the segment distal to the occlusion via contralateral coronary angiography. This technique requires the use of two catheters and two entry sites. The use of two entry sites increases the risk for entry-site complications and is uncomfortable to the patient. METHODS Careful rotation of a transradial multipurpose guide allows contralateral angiography while a guidewire is maintained in the occluded coronary artery. RESULTS This report describes 3 patients with successful contralateral angiography with the same guide as used for PCI. CONCLUSION Visualizing the contralateral artery with the same guide that is simultaneously used for angioplasty of the occluded coronary artery is feasible.
