Comparison of Bidirectional Palpation Test and Transit Time Flow Measurement for LIMA-LAD Graft Patency
Source: ClinicalTrials.gov · Last updated 8 Jul 2025
Brief summary (registry, in English)
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).

Other illness
- Patients in whom CT angiography is not appropriate: Such as acute or chronic renal failure
Lab values
- Inability to Perform CABG: Patients for whom CABG could not be performed due to postoperative complications (e.g., elevated creatinine levels leading to inability to perform CABG, 43 patients).
Other
- Refusal to Participate: Patients who did not wish to participate in the study after being approached.
- Death in Early Postoperative Period: Patients who died in the early postoperative period (3 patients).
Who the study is looking for
- Elective Isolated CABG Surgery: Patients undergoing elective isolated coronary artery bypass grafting (CABG).
- CABG with Additional Cardiac Surgery: Patients who had CABG surgery in conjunction with other cardiac procedures.
- Informed Consent: Patients who provided informed consent to participate in the study.
- Postoperative Follow-Up: Patients who were followed up postoperatively and completed the necessary evaluations.
- CABG patients whose renal functions are suitable for CTA
