Comparing achievability and reproducibility of pulsed wave doppler and tissue doppler myocardial performance index and spatiotemporal image correlation annular plane systolic excursion in the cardiac function assessment of normal pregnancies.
J Perinat Med
January 2025
Perinatal Imaging Research Group, School of Clinical Medicine, Discipline of Women's Health, Faculty of Medicine, University of New South Wales, Sydney, NSW, Australia.
Objectives: Multiple techniques have been proposed for functional fetal cardiology, including pulsed-wave (PW) and tissue Doppler imaging (TDI), Myocardial Performance Index (MPI), annular plane systolic excursion (TAPSE/MAPSE) and spatiotemporal image correlation (STIC). We aimed to compare these techniques' achievability and reproducibility to determine their clinical utility for each cardiac side.
Methods: Uncomplicated pregnancies from 22 to 39 weeks were recruited and images and volumes stored for offline analysis.
Could Pulsed Wave Tissue Doppler Imaging Solve the Diagnostic Dilemma of Right Atrial Masses and Pseudomasses? A Case Series and Literature Review.

Even if rarely detected, right atrial (RA) masses represent a diagnostic challenge due to their heterogeneous presentation. Para-physiological RA structures, such as a prominent Eustachian valve, Chiari's network, and lipomatous atrial hypertrophy, may easily be misinterpreted as pathological RA masses, including thrombi, myxomas, and vegetations. Each pathological mass should always be correlated with adequate clinical, anamnestic, and laboratory data.

The effects of T4 are mainly manifested by positive ino- and chronotropism. The syndrome accompanying hypothyroidism in rabbits (impaired myocardial contractility and reduced ejection capacity) is caused by a deficiency of thyroid hormones - especially T4. The study group consisted of a total of 41 animals: 15 males and 26 females, ranging in age from 2 months to 8 years, with echocardiogram showing reduced fractional shortening (<30%), with normal results of heamatological and biochemical tests.

There is scant information available about the blood flow of the pulmonary artery in avian cardiology. In human medicine, the shape of the Doppler sonographic blood flow profile of the pulmonary artery can be used to access the pressure conditions of the right heart. With this background, this study focused on the examination of the acceleration and deceleration phase of the pulsed-wave Doppler flow profile of the pulmonary artery of healthy racing pigeons.

Background: Mechanical ventilation (MV) is crucial for managing critically ill patients; however, extubation failure, associated with adverse outcomes, continues to pose a significant challenge.
Objective: The purpose of this prospective observational study was to develop and validate a predictive numerical model utilizing bedside ultrasound to forecast extubation outcomes in ICU patients.
Methods: We enrolled 300 patients undergoing MV, from whom clinical variables, biomarkers, and ultrasound parameters were collected.
