SUOH 03 Guidewire for the Management of Coronary Artery Dissection: Insights from a Multicenter Registry.

BACKGROUND

In the setting of coronary artery dissection, both spontaneous and iatrogenic, fixing the intimal tear, usually with stent implantation, can be extremely challenging if the distal wire position has been lost. Common complications are mainly related to the inadvertent subintimal tracking of the guidewire while attempting to gain the distal true lumen.

AIMS

To report the registry results of using the SUOH 0.3 guidewire for managing coronary artery dissection in a real-world multicenter setting.

METHODS

The study population in this retrospective, multicenter, international registry included 75 consecutive patients who underwent PCI and required an antegrade wiring of a dissected coronary artery.

RESULTS

Successful use of SUOH 0.3 was achieved in 69 (92%) patients. The use of a microcatheter was associated with a significantly higher rate of TIMI 3 flow at the end of the procedure (no microcatheter:  = 17, 81%; microcatheter:  = 52, 96.3%;  = 0.017). The first recanalization attempt was made with the SUOH 03 guidewire in 48 (64%) cases, and it was successful in 42 (87%). The overall PCI success rate was reported in 72 (96%) patients, with no significant differences among patients with different origins, mechanisms, and locations of dissection.

CONCLUSIONS

In this setting, the SUOH 0.3 guidewire provides high procedural success without additional complex techniques.
