Key result
Catheter-based 20-MHz intracardiac echocardiography safely yields high-resolution cardiac imaging in preclinical models.
Why the study?
The feasibility of imaging cardiac structures using 20-MHz ultrasound catheters had not been evaluated.
No takes yet. Share an insight, caveat, or question.
Supports catheter-based cardiac imaging development; leaves open human safety, efficacy, and clinical translation.
Pandian et al. (1991) studied this question. 20-MHz ultrasound catheters was evaluated on Feasibility of imaging cardiac structures. Intracardiac echocardiography using 20-MHz ultrasound catheters yielded high-resolution images of cardiac structures in 25 dogs without causing damage.
