Subclaims¶

q2 i? Coaptation depth improved significantly over time in both junior and senior resident groups (p < 0.001), and mean regurgitation score improved each month for junior residents (p < 0.02) and from the first to second and first to third months for senior residents (p < 0.02). → EL-Andari R 2023

q2 · i? · review · r3

Simulation-based study reported in the review: 10 cardiovascular surgery residents (5 junior, 5 senior) trained 3 months on a pressurized bovine heart model allowing "home-alone" surgical practice after 9 instructional videos, assessed monthly on coaptation depth and regurgitation score.

"Coaptation depth improved significantly over time in both groups (p < 0.001). Similarly, the mean regurgitation score improved each month for the junior residents (p < 0.02) and improved from the first to the second month and from the first to the third month for the senior residents (p < 0.02)."
