Cardiac ultrasound uses reflected sound waves (echos) to create images of anatomy inside the body. Echocardiograms are the primary cardiac imaging modality used to assess the heart and diagnose or track cardiac issues. Echo is the gold standard imaging modality to assess the heart, particularly with calculating left ventricular ejection fraction (LVEF), which is a measure of cardiac output. In addition to noninvasive standard transthoracic echo (TTE), invasive transesophgeal echo (TEE) is also used when clearer, more detailed imaging of the heart is needed. Both 3D and 4D echo echo systems are rapidly gaining wider adoption and enable new types of assessments, especially in the structural heart space and in transcatheter procedural guidance.

An example of HeartFlow's new RoadMap Stenosis software that uses artificial intelligence (AI) to show areas of interest for possible stenting based on a patient's CT scan and FFR-CT. This software is still undergoing beta testing at several hospitals and will likely be rolled out commercially later in 2023.

Cardiology has embraced AI more than most other specialties

Cardiology is linked to the second largest group of FDA-cleared clinical AI algorithms, and the number is still growing.

X-ray photon trajectory during the simulation phantom study from the side and top views. Due to scattering of the X-rays when they hit the lower end of the patient bed, exposure in mainly to the lower body of the interventional echocardiographer performing transesophageal echocardiography. The green lines are the scattered photon trajectories calculated by Monte Carlo simulation in the study.
