L’électrocardiogramme (ECG) à 12 dérivations demeure un examen fondamental du diagnostic cardiovasculaire, avec plus de 300 millions d’examens réalisés chaque année dans le monde. Les solutions d’IA existantes pour l’interprétation automatisée manquent souvent de généralisabilité, restent propriétaires et reposent sur un apprentissage supervisé nécessitant de vastes ensembles de données étiquetées.

Accurate left ventricular ejectionfraction (LVEF) assessment is crucial in acute coronary syndrome (ACS)management but traditional methods like echocardiography (TTE) andventriculography have limitations such as risks, contrast exposure, andlogistical delays.The CathEF study introduced adeep-learning algorithm integrated with the PACS-AI (www.pacsai.co) platform,providing real-time LVEF estimates directly from routine coronary angiographyvideos, without extra catheterization or contrast.

Atrial fibrillation is the most common sustained cardiac arrhythmia in adults and is associated with an increased risk of stroke, heart failure, cognitive decline, hospitalisations, and death. Deep learning applied to electrocardiograms (ECG-AI) is an emerging approach for predicting atrial fibrillation or flutter (AF). We introduce an open-weights ECG-AI model developed at the Montreal Heart Institute (MHI) and externally validated using MIMIC-IV dataset, comparing its performance with clinical and AF polygenic scores (PGS).

Coronary artery disease involves the narrowing of heart blood vessels of the heart, also known as. stenoses, and stands as a major global cause of mortality, requiring accurate evaluation for effective treatment. The existing gold standard for assessing stenosis severity, which relies on visual interpretation of coronary angiography videos by cardiologists, shows significant variability, highlighting the necessity for standardized, objective methods. AI-based algorithms have been developed to overcome this issue, but these methods have inherent limitations which are addressed with DeepCoro.

Coronary heart disease (CHD) is the leading cause of adult death worldwide. The minimally-invasive procedure called coronary angiography provides the primary gateway for nearly all CHD diagnosis and clinical management decisions, as well as stent-based therapy for CHD.

A team of researchers at UCSF developed a technology called CathEF that uses artificial intelligence (AI) to assess how well the heart pumps blood during a common heart test.
