Key result

Contrast-enhanced convex echocardiography improves RV apical visualization and RVFAC reliability vs sector transducers in dogs.

n=10

Why the study?

Accurate assessment of right ventricular wall thickness, myocardial visualization, and chamber dimensions is crucial in veterinary cardiology but remains understudied in dogs.

Does the use of convex transducers and contrast agents improve right ventricular visualization and fractional area change measurement in healthy dogs compared to sector transducers?

Population

10 healthy beagle dogs

Comparison

Sector transducer vs convex transducer vs convex transducer with contrast agent

Design

Prospective observational study

Implication

Supports contrast-enhanced convex echocardiography for RVFAC in dogs; extends visualization reliability in veterinary cardiology.

Key Points

The aim is to assess right ventricular wall thickness, myocardial visualization, and fractional area change in dogs using different echocardiographic approaches.
Prospective observational study design
Evaluation of 10 healthy beagle dogs
Comparison of sector and convex transducers with and without a contrast agent
Statistical analyses using paired t-tests and ANOVA
Convex transducers showed better myocardial visualization and observer agreement compared to sector transducers.
Contrast-enhanced echocardiography significantly improved apical visualization of the right ventricle.
Mean right ventricular fractional area change with contrast was 36.1% ± 7.3%, with good observer reliability (ICC 0.7).

Park et al. (2026) conducted an observational in Healthy beagle dogs (n=10). Convex transducer with or without contrast agent vs. Sector transducer was evaluated on Myocardial visualization and inter-observer agreement. Convex transducers offered superior visualization and inter-observer agreement in near-field segments compared to other approaches (ICC: 0.12-0.92 vs. 0.06-0.73).
