Non-invasive derivation of instantaneous free-wave ratio from invasive coronary...
Oliveira, Catarina; Vilela, Marta; Silva Marques, João; Jorge, Claudia; Rodrigues, Tiago; Francisco, Ana Rita; Oliveira, Rita Marante deInvasive coronary physiology is underused and carries risks/costs. Artificial Intelligence (AI) might enable non-invasive physiology from invasive coronary angiography (CAG), possibly outperforming humans, but has seldom been explored, especially for instantaneous wave-free Ratio (iFR). We aimed to develop binary iFR lesion classification AI models and compare them with human performance. single-center retrospe...
Coronary intravascular lithotripsy effectiveness and safety in a real-world cohort
Oliveira, Catarina; Vilela, Marta; Menezes, Miguel Nobre; Silva Marques, João; Jorge, Claudia; Rodrigues, Tiago; Almeida Duarte, JoséBackground: Coronary artery calcification is a predictor of adverse outcomes after percutaneous coronary intervention (PCI). Intravascular lithotripsy (IVL) is a promising tool for the treatment of calcified lesions. The aim of this study was to assess the effectiveness and safety of IVL. Methods: A single-center observational study of PCI procedure, with assessment of the outcomes of patients undergoing PCI us...
Coronary artery calcium identified on non-gated chest CT scans: a wasted opport...
Valente Silva, Beatriz; Menezes, Miguel Nobre; Plácido, Rui; Jorge, Claudia; Rigueira, Joana; Garcia, Ana Beatriz; Martins, Ana MargaridaBackground: Coronary artery calcium (CAC) evaluated on dedicated cardiac computed tomography (CT) is an independent predictor of cardiovascular events. This study aimed to evaluate the correlation between CAC detected on non-gated standard chest CT and coronary lesions on coronary angiography (CAG) and determine its impact on prognosis. Methods: Consecutive patients who underwent CAG due to acute coronary syndr...
