Résumé
Balloon uncrossable coronary lesions are lesions that cannot be crossed with a conventional balloon. Multiple balloons have been designed to overcome this problem. The Blimp balloon has a very low scoring profile (0.6 mm) with a very high rated burst pressure (30 atmospheres). We aimed to evaluate the efficacy of this balloon compared to customary low-profile balloons. We conducted a multicenter, prospective, randomised, controlled trial in which 126 patients with an uncrossable lesion were randomly (1:1 randomization) assigned to treatment first with the Blimp balloon or low-profile balloon. The primary endpoint was the success of crossing the lesion after initial failure with a microcatheter (group A) or with a conventional balloon (group B). Overall, the first attempt of Blimp was successful in 29 out of 61 cases (48%) while the LP balloon immediately crossed in 30 out 67 cases (45%; The Blimp balloon catheter showed no superiority to customary low-profile balloons in uncrossable lesions. It can however be complementary in treating uncrossable lesions.

BACKGROUND
UNASSIGNED
Balloon uncrossable coronary lesions are lesions that cannot be crossed with a conventional balloon. Multiple balloons have been designed to overcome this problem. The Blimp balloon has a very low scoring profile (0.6 mm) with a very high rated burst pressure (30 atmospheres). We aimed to evaluate the efficacy of this balloon compared to customary low-profile balloons.
METHODS
UNASSIGNED
We conducted a multicenter, prospective, randomised, controlled trial in which 126 patients with an uncrossable lesion were randomly (1:1 randomization) assigned to treatment first with the Blimp balloon or low-profile balloon. The primary endpoint was the success of crossing the lesion after initial failure with a microcatheter (group A) or with a conventional balloon (group B).
RESULTS
UNASSIGNED
Overall, the first attempt of Blimp was successful in 29 out of 61 cases (48%) while the LP balloon immediately crossed in 30 out 67 cases (45%;
CONCLUSIONS
UNASSIGNED
The Blimp balloon catheter showed no superiority to customary low-profile balloons in uncrossable lesions. It can however be complementary in treating uncrossable lesions.
