Is there the phenotype of chronic heart failure with “intermediate” left ventricular ejection fraction? Additional echocardiographic criteria for left ventricular systolic dysfunction in patients with chronic heart failure of ischemic origin with ejection fraction in the “gray area”

Zaporožskij Medicinskij Žurnal, 2021
Patients with chronic heart failure (CHF) with left ventricular ejection fraction (LV EF) in the range of 40–55 % form a separate group with “intermediate” or “moderately reduced” LV EF. Since there are a number of additional criteria in echocardiography

Color Flow Doppler Echocardiography in Healthy Racing Pigeons (Columba livia f. domestica) and the Evidence of Physiological Blood Flow Vortex Formations

Veterinary Sciences, 2020
In avian medicine, Doppler sonographic techniques are used to visualize and estimate blood flow in the heart. In the literature there is a lack of standardized studies of the use of color Doppler flow on healthy avian species.
