The Ringer Study: Clinical Experience with a Novel Perfusion Balloon Catheter in CAP

Video Transcription

Video Summary

This video features a panel discussion on the Ringer Perfusion Balloon Catheter, a novel device for managing coronary artery perforations, which are rare but serious complications during percutaneous coronary interventions. The Ringer catheter is a rapid-exchange angioplasty balloon that uniquely inflates into a hollow cylinder, enabling simultaneous sealing of the perforation and continuous antegrade coronary flow, unlike traditional balloons that cut off blood flow. The first-in-human RINGER study, conducted across four US centers, enrolled 30 patients with complex coronary perforations. Results showed 87% successful device delivery and 85% effective sealing with maintained TIMI 2/3 flow during balloon inflation, averaging 20 minutes. Nearly half the patients required no further intervention post-Ringer use. Safety was affirmed with no device-related adverse events. Experts emphasized the device's technical advantages: deliverability, compatibility with other catheters, and use as a conduit for additional therapies. While not suitable for distal small branch perforations, the Ringer balloon is a promising, FDA-pending tool to improve outcomes in managing life-threatening coronary perforations.
