| Abstract | ||
| Background: Cardiovascular diseases (CVDs) account for about one third of all global mortalities and are a major contributor to disability. The aim of this study was to evaluate the early clinical and angiographic outcomes of left anterior descending (LAD) reconstruction using the left internal mammary artery (LIMA) patch versus the GSV. Methods: This clinical comparative study included 80 patients diagnosed with ischemic heart disease (IHD) who were divided into two groups, group A (LIMA group) included 40 patients underwent LAD reconstruction using a LIMA patch and group B (GSV group) included 40 patients underwent LAD reconstruction using a great saphenous vein (GSV) patch. Follow-up was every 2 weeks, 1 month, 3 months, and 6 months postoperative then annually via outpatient visits. Echocardiography, multi-slice computed tomography coronary angiography or coronary angiographies were performed at 6–12 months to assess anastomosis patency. Results: There was a statistically significant difference regarding NYHA classification, indicating a better functional status in the LIMA group. There was a statistically significant difference in LVED, indicating that reduction was greater in the LIMA group. This suggested better left ventricular remodeling in LIMA group postoperatively. There was a statistically significant difference in ejection fraction, indicating that improvement was significantly higher in the LIMA group compared to the GSV group. This suggested better myocardial recovery and contractile function in the LIMA group postoperatively. Conclusion: LIMA adoption for reconstruction of diffusely diseased LAD is associated with favorable operation, early and short-term outcome as regard lower MACES, lower rehospitalization and superior patency rate. | ||
