A-72-year-old male underwent coronary angiography, which revealed a severe stenosis of the left anterior descending artery with an extremely angulated diagonal branch. We introduced the Crusade (Kaneka, Osaka, Japan) accompanied with the reversed guidewire to the lesion, but the Crusade with the reversed guidewire could not cross the lesion. We kept the Crusade at the just proximal to the stenosis, and advanced the only reversed guidewire to the lesion. The reversed guidewire successfully crossed the lesion, and then we pulled back the reversed guidewire to lead the reversed guidewire’s tip into the diagonal branch retrogradely. In this modified reverse guidewire technique, the Crusade does not need to cross the lesion, but needs to bring the reversed guidewire at the just proximal of the lesion. Because the profile of the reversed guidewire alone is smaller than that of the Crusade accompanied with the reversed guidewire, the reversed guidewire alone has greater chance to cross the severe stenosis. Our modification may increase the success rate of the reverse guidewire technique, and expand the indication of this technique.<Learning objective: In a reverse guidewi...
