Abstract

OBJECTIVE:

To develop a new technique of bilateral angiography in a single radial access (BASiRalA) which can reduce a puncture site.

METHODS:

From March 2011 to February 2012, 13 cases of coronary heart disease patients with chronic total occlusion (CTO) were treated (6 CTOs in right coronary artery and 7 in left anterior descending artery). All patients underwent percutaneous coronary intervention (PCI) via the right radial artery access and 6 F guiding catheters were delivered to the diseased artery. Once the wires crossed the CTO lesions and were uncertain if the wires were in true lumen or not, BASiRalA was performed. The Finecross microcatheters were advanced out of the 6 F guiding catheter, then withdraw 6F guiding catheter to the opening of diseased artery, the soft wires were manipulated into the middle portion of opposite coronary artery. After that, the microcatheters were advanced to this segment or the branches relative to the collateral vessels connected with CTOs. After pulling out the wires, microcatheter injections can be performed for contralateral angiography. BASiRalA related complications were observed after the procedure.

RESULTS:

BASiRalA technique was applied to 13 CTOs and 10 procedures succeeded (76.92%). BASiRalA failed in 3 cases and the wires and microcatheters could not be advanced to the opposite coronary arteries within 20 minutes. Alternatively, contralateral angiography via femoral arteries was performed in these 3 patients. The average time of BASiRalA technique was 7 (5 - 13) minutes and the shortest time of wires crossing to the opposite coronary artery was 5 seconds. There was no procedure induced complication during procedure or post procedure.

CONCLUSION:

BASiRalA technique is feasible in treating CTO patients by PCI.
