Brief summary
This study evaluates whether healthcare providers without specialized ultrasound training can use UltraSight's machine learning based Guidance Software to perform limited transthoracic echocardiography in patients with hypertrophic obstructive cardiomyopathy (HOCM), who are receiving or eligible for mavacamten (Camzyos™). Participants will undergo two heart scans on the same day, one by a non-sonographer using the software and one by a trained sonographer. The study aims to determine if the software-guided images are comparable in quality, with the goal of expanding access to heart monitoring for HCM patients.
Detailed description
This study is evaluating whether healthcare providers without specialized ultrasound training can use UltraSight's Guidance Software to perform heart ultrasound exams (limited transthoracic echocardiography) in patients with hypertrophic obstructive cardiomyopathy (HOCM) who are receiving or eligible for treatment with Camzyos™ (mavacamten). The study aims to determine if the software-guided images are comparable to those taken by the sonographers, in quality. Participants will receive two echocardiography scans on the same day (one by a non-sonographer using UltraSight's Guidance Software and one by a sonographer), and the image quality will be reviewed by expert cardiologists. The study aims to increase patients' access to cardiac monitoring, especially for this patient population, by enabling more healthcare professionals to perform these echocardiography exams safely and effectively.

Inclusion criteria
1. Male and female subjects aged 18 years or over at the time of screening. 2. Willing and able to give written informed consent. 3. New York Heart Association (NYHA) Class I to III 4. Eligible to receive or currently receiving CamzyosTM per product labelling.
Exclusion criteria
1. Emergency (non-elective) admission within 24 hours prior to participating in the study. 2. Unable to lie down as required in all the classic positions for standard TTE exam: supine on back/left decubitus. 3. Subjects who had technically difficult exam in the past, due to body habitus, upon investigator's discretion. 4. Subjects with body mass index (BMI) above 40 kg/m2. 5. Subjects experiencing a known or suspected acute cardiac event. 6. Subjects with severe chest wall deformities as per previous medical records and physical examination. 7. Subjects who have undergone pneumonectomy. 8. Subjects whose anatomy does not lend itself to yield diagnosable echocardiography clips (i.e., situs inversus with dextrocardia, single ventricle anatomy due to congenital heart defect, etc.).
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Agreement in Left Ventricular Ejection Fraction (LVEF) | 1 day | To demonstrate agreement in echocardiography data between limited transthoracic echocardiography (LTTE) exams performed by non-sonographer healthcare professionals (HCPs) using the UltraSight Software and exams performed by trained sonographers. LVEF will be assessed using Simpson's Method and categorized into predefined groups. The expert cardiologists evaluating the LVEF will be blinded to the exam performer's identity. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Agreement in Quality level of Specific Echocardiographic Views Between Non-Sonographer HCPs and Sonographers, using ACEP echocardiography images' quality scale | 1 day | To demonstrate agreement in the quality of specific echocardiographic views obtained by non-sonographer healthcare professionals (HCPs) using the UltraSight Software compared to those obtained by trained sonographers. Quality will be assessed by blinded expert cardiologists using the 5-point American College of Emergency Physicians \[ACEP\] scale), for each of the following views: Parasternal Long-Axis (PLAX), Apical 2-Chamber (Apical 2C), Apical 3-Chamber (Apical 3C), Apical 4-Chamber (Apical 4C), Apical 5-Chamber (Apical 5C). |
| Number of participants with adverse events (AEs) as assessed by CTCAE v4.0 | 1 day | The number of AEs, SAEs, and device related AEs will be captured as well as the number of subjects who discontinue due to an AE. |
