Previous studies reported that left ventricular systolic dysfunction in severe aortic
stenosis (AS) with preserved ejection fraction was reflected in the global longitudinal
strain (GLS) by transthoracic echocardiogram (TTE). Recently three-dimensional maximum
principal strain could be measured using cardiac CT. A 68-year-old man was admitted
due to chest pain. Coronary CT angiography showed no significant coronary stenosis.
A TTE revealed severe AS with an aortic valve area of 0.69 cm2 and mean pressure gradient of 49 mmHg, and an aortic peak velocity of 4.4 m/s. GLS
recovered at 1 year after aortic valve replacement (AVR) compared to that before AVR
(−16.1% vs −13.6%). The decreased average peak maximum principal strain value in this
patient was improved after surgery (0.38 vs 0.54). We report this case with some literature
review.
