Abstract: A 90-year-old woman underwent transcatheter aortic valve replacement (TAVR). After the implantation of a selfexpandable valve, paravalvular leak (PVL) was found at posteromedial side (Fig. 1a, b). The regurgitation jet on the color Doppler image… read more here.

Abstract: Electrocardiogram (ECG) is often used together with a spectral Doppler ultrasound to separate heart cycles by determining the end-diastole locations. However, the ECG signal is not always recorded. In such cases, the cardiac cycles can… read more here.
