Introduction: Proper sizing of the aortic annulus is vital in selecting the most appropriate valve size during open aortic valve replacement. The aortic annulus diameter measured by preoperative transthoracic echocardiography or CT scan, often yields different values than the prosthetic valve annulus measured intraoperatively and the same has been implicated in frequent paravalvular leakage, PPM, thromboembolism and endocarditis. In our study we evaluated the accuracy of valve sizing obtained by preoperative CT scan and echocardiography by comparing these measurements with direct intraoperative sizing.

Methods: Total 100 patients undergone standard open surgical valve replacement in our institution between January 2019 to December 2019 were retrospectively analyzed. Their maximum aortic annulus diameter determined by preoperative CT scan and echocardiography were individually compared and correlated statistically with the implanted valve size.

Results: The systolic annulus diameter by transthoracic echocardiography and the effective diameter by CT scan correlated better with the intraoperative sizing.

Conclusion: The effective diameter measured by CT scan correlates most with the intraoperative sizing so it can serve as an indicator for deciding the most appropriate size of prosthetic valve intraoperatively.
