Surgical Measurement for Accurate Revascularization Using Transit-time FLOW (SMARTFLOW):Patency
Weill Medical College of Cornell University
Summary
The purpose of this study is to learn more about a tool called Transit-Time Flow Measurement (TTFM). TTFM uses sound waves during surgery to check how well blood is flowing through blood vessels. This helps doctors see if the blood flow is good during coronary artery bypass grafting (CABG), which is a type of heart surgery
Description
The SMARTFLOW:Patency trial is designed to fill this critical evidence gap by evaluating the impact of CABG graft quality assessment by TTFM on clinical outcomes in a large randomized cohort. SMARTFLOW:Patency will evaluate the impact of CABG graft quality assessment by TTFM on graft patency.

Interventions
- DeviceTransit-Time Flow Measurement (TTFM)
TTFM is based on ultrasound technology and allows the assessment of intraoperative graft function based on quantification, directionality and resistance to blood flow through the graft.
