Key result
LAD reconstruction using LIMA or vein patch angioplasty significantly improved mean NYHA functional class from 3.6 preoperatively to 1.2 postoperatively (P<0.001).
Observational (n=40)
Yes
Absolute Event Rate: 1.2% vs 3.6%
p-value: p=<0.001
Patch angioplasty using LIMA or saphenous vein for diffusely diseased LAD is a feasible and safe surgical technique that provides significant early symptomatic improvement.
May support symptomatic relief in diffuse LAD disease; hypothesis-generating and requires validation in prospective cohorts.
Background: Severely diseased left anterior descending coronary artery (LAD) is a surgical challenge and several procedures were suggested to achieve adequate reconstruction.

Ahmed Attia (2014) conducted an observational in Diffusely diseased left anterior descending coronary artery (n=40). Patch angioplasty (LIMA or saphenous vein patch) vs. Preoperative baseline was evaluated on NYHA functional class (p=<0.001). LAD reconstruction using LIMA or vein patch angioplasty significantly improved mean NYHA functional class from 3.6 preoperatively to 1.2 postoperatively (P<0.001).
