Key result
In situ RITA bypass via the transverse sinus demonstrated a 6-year cumulative patency rate of 89.3%, which was not significantly different from the 94.5% patency rate of LITA grafts.

Supports in situ RITA via transverse sinus for comparable patency; leaves open randomized confirmation of long-term equivalence.
Cohort (n=115)
Does in situ RITA bypass via the transverse sinus provide comparable long-term patency to LITA grafts in patients undergoing coronary revascularization?
Absolute Event Rate: 89.3% vs 94.5%
In situ RITA bypass via the transverse sinus demonstrates good long-term patency comparable to LITA grafts, supporting its continued use for revascularization.
Ura et al. (1998) conducted a cohort in Coronary artery disease requiring revascularization (n=115). In situ RITA bypass via the transverse sinus vs. Left internal thoracic artery (LITA) grafts was evaluated on Cumulative patency rate at 6 years. In situ RITA bypass via the transverse sinus demonstrated a 6-year cumulative patency rate of 89.3%, which was not significantly different from the 94.5% patency rate of LITA grafts.
