Objectives: To evaluate the safety and technical utility of the short track sliding (STS) balloon catheter. Background: An STS balloon catheter is designed to ensure a low profile at the shaft and perform distal anchoring using a single guidewire. However, its clinical practice with the STS balloon catheter has not been reported. Methods: This prospective multi-center registry enrolled 100 patients with significant coronary artery disease who had undergone percutaneous coronary intervention using an STS balloon catheter at three hospitals in Korea from March 2019 to July 2020. Overall safety was assessed as any occurrences of device-related malfunction during the pre-dilation of the lesions. Its technical success rates of the kissing balloon technique or the distal anchoring technique using a single guidewire were also evaluated. Results: Of the 118 lesions pre-dilated using the STS balloon, no significant complication was observed except for three significant coronary dissections, which were completely covered with stents. There was no incidence of balloon catheter malfunction, such as fracture, entrapment, or perforation. With 13 attempts of kissing ballooning techniques with the STS balloon with a 6F guiding catheter, all cases were successful. The distal anchoring techniques were attempted in 10 cases, the stent was successfully crossed to the target lesion in all 10 cases. Conclusions: The novel STS balloon catheter can be safely applied in routine coronary intervention with minimal complications. In addition, this catheter could be useful for performing the kissing balloon technique with a small-caliber guiding catheter and distal anchoring technique with a single guidewire.
