Comparison of Bidirectional Palpation Test and Transit Time Flow Measurement for LIMA-LAD Graft Patency
In Brief
An observational study for Coronary Arterial Disease (CAD) and 7 related conditions. Completed, enrolled 116 participants across 1 site.
Detailed Summary
The most important factor determining mortality and morbidity after coronary artery bypass graft (CABG) surgery is graft patency. The LIMA-LAD anastomosis is the most crucial anastomosis because it's revascularizing the most important and large region of the heart, has superior long-term graft patency rates and is considered the gold standard for CABG. Therefore, ensuring the patency of the LIMA-LAD anastomosis is vital for both early and late outcomes. The bidirectional palpation test (BPT), developed in our clinic to assess graft patency, is a subjective test, yet it is simple and reliable. Additionally, transit time flow meter (TTFM) measurements have also been performed. In this study, the efficacy of BPT and the results of TTFM measurements were compared by examining graft patency through early-period coronary CT angiography (CCTA).
