Abstract
BACKGROUND: Small aortic root is an unexpected incident during surgical aortic valve replacement in which the prosthesis valve size does not match the case being treated. CASE PRESENTATION: Two patient-prosthesis mismatches with aortic valve problems underwent surgical aortic valve replacement. Based on calculating the body surface area (BSA) and effective orifice area (iEOA), the selection of prosthesis valve size was determined. When minor aortic root surgery was performed, it was discovered that the procedure of aortic root enlargement had to be conducted. The surgery went smoothly, but both patients had different outputs. The first patient was dead, while the second patient had a better quality of life. DISCUSSION: Every surgical aortic valve replacement preparation of aortic root enlargement procedure needs to be prepared for the worst-case scenario. CONCLUSION: Aortic root enlargement procedure must be anticipated in aortic valve replacement, especially for the patients with small aortic roots, both isolated and with concomitant valve procedure.
