Abstract:
Crossing of a critically stenosed aortic valve is a pivotal step during diagnostic cardiac catheterization to measure the transvalvular gradient, especially in patients with discordant clinical and echocardiographic findings and also during transcatheter aortic valve replacement procedures. However, there are no data in the literature indicating whether aortic valve crossing typically occurs during systole or diastole. We hypothesize that aortic valve crossing is a diastolic phenomenon and describe our technique for crossing critically stenosed aortic valves.

Critical Region, Critical Values and Significance Level
In hypothesis testing, a sample statistic is converted to a test statistic using z, t, or chi-square distribution. A critical region is an area under the curve in probability distributions demarcated by the critical value. When the test statistic falls in this region, it suggests that the null hypothesis must be rejected. As this region contains all those values of the...
