The study's objective is to evaluate if exams, performed with the HeartFocus software by novices, are of sufficient quality to visually analyze the left ventricular size, the left ventricular function, the right ventricular size, and the presence of non-trivial pericardial effusion.
Novices will be nurses without prior ultrasound experience who have received dedicated training on cardiac ultrasound and on Heartfocus software. Ultrasound exams will be limited to the acquisition of 10 reference views
This prospective multicentric international pivotal trial will evaluate the ability of the Heartfocus software to support novices for the acquisition of 10 reference views of cardiac ultrasound. The 10 reference views are the following:
Parasternal long axis, Parasternal short axis at the aortic valve, Parasternal short axis at the mitral valve Parasternal short axis at the papillary muscles Apical 5-chamber, Apical 4-chamber, Apical 3-chamber, Apical 2-chamber, Subcostal 4-chamber, Subcostal inferior vena cava.
Patients included in the study will be adult patients scheduled for an echocardiogram at one of the two investigating centers. Ultrasound exams will be limited to the acquisition 10 reference views.
Patients will receive 2 additional limited exams, which consist of the acquisition of ultrasound clips for each of the 10 references views:
one by a novice, nurses having received a dedicated training of 2 days, with an ultrasound probe and the HeartFocus software with the guidance system, one by an expert (experienced sonographer/cardiologist) with the same ultrasound probe and the HeartFocus software without the guidance system.
A total of 8 novices will perform the acquisition on 30 patients each. In total 240 patients will be included in the study, half in each investigator center. The exams (240 acquired by novices, 240 by experts) will be analyzed by cardiologists to assess their quality. The endpoints are described below.

A total of 247 patients were screened. Of these, 246 provided informed consent; among these, 6 participants withdrew before undergoing the study echocardiography. Reasons included withdrawal of consent (n=3), scheduling conflicts (n=2), and technical difficulties (n=1). Thus, 240 patients were finally enrolled in this study, meaning that they completed both novice and expert echocardiography exams and were included in the Full Analysis Set.
Adult patients (≥18 years) scheduled for a clinically indicated echocardiogram were consecutively recruited at two academic medical centers: University Hospital of Bordeaux (France) and Lenox Hill Hospital (New York, USA). Recruitment occurred between november 2023 and august 2024.
