What is Tardus-Parvus Doppler Waveform in Both Kidneys in an Adult Patient Suggesting Aortic Coarctation about?

Purpose: The aim of this research was to study the changes of renal hemodynamics in patients with heart failure and arterial hypertension. Material & Methods: We studied 63 normal persons (control), 70 untreated patients with arterial hypertension (AH) without heart failure (I group) and 56 untreated patients with arterial hypertension and heart failure (HF) (II group). Renal arterial flow was studied by intrarenal Dopplerography, which was registered from interlobar arteries of both kidneys. It was measured as: maximal systolic (Vmax) and diastolic (Vmin) velocities, acceleration time (AT) and acceleration (ACC) of systolic flow and calculated resistive index (RI). Results: There was no significant difference in renal flow parameters between normal persons and patients with AH. In patients with HF, the Vmax, RI and AT was significantly higher, and Vmin lower than in controls and patients of I group. RI was more than 0,7 in 48,21% of patients in II group, only in 8,57% of patients in I group and 6,35% of controls. In patients with heart failure, RI was in positive correlation with age, HF HYHA functional class, mitral flow A wave velocity and tricuspid flow E wave velocity, and in
