Methods
We included 46 patients with mild mitral stenosis (mitral valve area>1.5 cm2) between January 2015-January 2016. The patients were evaluated with comprehensive 2D and Doppler echocardiography during rest, before the exercise stress test. Left atrial and ventricular peak systolic strain values were calculated by using a software program (Figure 1&2). Exercise stress test was then performed by using treadmill with standard Bruce protocol. All of the patients completed the test successfully and reached the 85% of age predicted maximal heart rate. Immediately after the termination of the test, the echocardiographic examination was repeated.
