Why the study?

It remained unclear whether root computed tomography angiography produces reliable measurements of virtual basal ring and geometric height for aortic valve repair and valve-sparing surgery.

Does root computed tomography angiography accurately measure virtual basal ring and geometric height compared to intraoperative measurements in patients eligible for aortic valve repair?

Population

238 patients with good quality image data

Comparison

Computed tomography vs intraoperative measurements and TTE

Key result

Root computed tomography angiography accurately measured virtual basal ring and geometric height with ICCs up to 0.98, aiding surgical planning in 238 patients.

Overview

May aid aortic valve repair planning; extends echocardiographic data but leaves open prospective validation.

Key Points

  • The study aims to evaluate the accuracy of root computed tomography angiography in measuring the virtual basal ring and geometric height for aortic valve procedures.
  • Evaluated the virtual basal ring and geometric height using computed tomography and intraoperative measurements.
  • Assessed the virtual basal ring with transthoracic echocardiography (TTE).
  • Utilized the Bland-Altman method to evaluate consistency among measurements.
  • Included 238 patients with quality image data.
  • Measured virtual basal ring as 26.42 mm (TTE), 28.83 mm (CT), and 28.06 mm (intraoperatively) with high consistency (ICC: 0.96-0.98).
  • Geometric height measurements showed ICC of 0.97-0.98 across various cusps, indicating reliable outcomes.
