Recanalization of Complex Coronary Chronic Total Occlusions Using High‐Frequency Vibrational Energy CROSSER Catheter as First‐Line Therapy: A Single Center Experience

Recanalization of Complex Coronary Chronic Total Occlusions Using High‐Frequency Vibrational... Background: Several studies have illustrated the safety and the procedural outcome of high‐frequency vibrational energy in guidewire refractory chronic total occlusions (CTOs). Aim: To evaluate the advantage of high‐frequency vibrational energy device (CROSSER Catheter) use in coronary complex CTO revascularization as primary strategy. Methods: CROSSER was used as a primary approach if four or more unfavorable angiographic features were observed in the CTO lesions. Results: From May 2007 to February 2009, a CTO percutaneous intervention attempt was performed in 178 lesions of 171 patients (60.1 ± 8.9 age with 49.4 ± 7.2% in ejection fraction). Among these, the CROSSER was used in 46 complex CTO lesions of 45 patients (25.8% of cases) and in the remaining cases, typical CTO percutaneous coronary intervention techniques were employed. Clinical success was 84.8% in CROSSER group. Moreover, in the CROSSER group, no periprocedural myocardial infarction, perforation, or 30 days MACE was observed. In addition, the use of CROSSER was associated with lower time of procedure, time of fluoroscopy, and contrast load administration as compared with conventional techniques (88 ± 27 minutes vs 109 ± 38 minutes (P = 0.045), 39 ± 12 minutes vs 50 ± 27 minutes (P = 0.032), and 334 ± 122cc vs 408 ± 198cc (P = 0.05), respectively). Conclusion: In the present study, the CROSSER System was safe and obtained a high rate of success in complex CTO similar to conventional dedicated guidewire techniques for noncomplex CTO; however, the CROSSER Catheter obtained CTO recanalization with lower contrast load administration, less time of procedure, and lower fluoroscopy exposure.

Abstract

Background: Several studies have illustrated the safety and the procedural outcome of high‐frequency vibrational energy in guidewire refractory chronic total occlusions (CTOs). Aim: To evaluate the advantage of high‐frequency vibrational energy device (CROSSER Catheter) use in coronary complex CTO revascularization as primary strategy. Methods: CROSSER was used as a primary approach if four or more unfavorable angiographic features were observed in the CTO lesions. Results: From May 2007 to February 2009, a CTO percutaneous intervention attempt was performed in 178 lesions of 171 patients (60.1 ± 8.9 age with 49.4 ± 7.2% in ejection fraction). Among these, the CROSSER was used in 46 complex CTO lesions of 45 patients (25.8% of cases) and in the remaining cases, typical CTO percutaneous coronary intervention techniques were employed. Clinical success was 84.8% in CROSSER group. Moreover, in the CROSSER group, no periprocedural myocardial infarction, perforation, or 30 days MACE was observed. In addition, the use of CROSSER was associated with lower time of procedure, time of fluoroscopy, and contrast load administration as compared with conventional techniques (88 ± 27 minutes vs 109 ± 38 minutes (P = 0.045), 39 ± 12 minutes vs 50 ± 27 minutes (P = 0.032), and 334 ± 122cc vs 408 ± 198cc (P = 0.05), respectively).
