Cardio-Obstetric Mortality Risk (CO-RISK) Model: Explanation and Clinical Context The CO-RISK model, derived from the CARPREG II score, assesses the risk of primary cardiac events in pregnant women with heart disease. This model assigns points based on the presence of specific cardiac risk factors, including prior cardiac events, NYHA functional class, mechanical valve, left ventricular dysfunction, high-risk valve d
CARPREG II Score (2018 Updated Version): Explanation and Clinical Context The CARPREG II risk score is an evidence-based tool to estimate the risk of maternal cardiac complications during pregnancy for women with structural heart disease. It uses clinical variables including prior cardiac events or arrhythmia, baseline NYHA class > II or cyanosis, mechanical heart valve, reduced systemic ventricular function (EF <40%
: Explanation and Clinical Context This tool provides a simplified risk estimate for a composite adverse outcome (including mortality, major complications such as moderate‑severe paravalvular leak, pacemaker implantation, or valve thrombosis) at 1 year after transcatheter aortic valve replacement (TAVR) using either a self‑expandable device (e.g., CoreValve) or a balloon‑expandable device (e.g., Sapien). The model in

CT-Based Annulus Sizing Index: Explanation and Clinical Context The CT-Based Annulus Sizing Index is a quantitative parameter used to assess the relationship between the native aortic annulus size (derived from CT imaging) and the selected transcatheter heart valve (THV) size. It provides an objective measure of oversizing or undersizing during pre-procedural transcatheter aortic valve replacement (TAVR) planning. Th
