CMR Late Enhancement Pericarditis Index (LEPI) Calculator

CMR Late Enhancement Pericarditis Index (LEPI): Explanation and Clinical Context The CMR LEPI is a quantitative tool developed to assess the severity and risk stratification in patients with acute or chronic pericarditis using cardiac magnetic resonance imaging. It integrates three key parameters: pericardial late gadolinium enhancement (LGE) score, pericardial thickness measured on imaging, and pericardial edema det

Constriction Probability Score (Echo-based) Calculator

Constriction Probability Score (Echo-based): Explanation and Clinical Context The Constriction Probability Score (Echo-based) is a diagnostic tool designed to assess the likelihood of constrictive pericarditis using echocardiographic parameters. This score incorporates key measurements such as Left Atrial Volume Index (LAVI), Right Atrial Volume Index (RAVI), Tricuspid Annular Plane Systolic Excursion (TAPSE), and Tr

CT Pericardial Thickness Index (PTI) Calculator

CT Pericardial Thickness Index (PTI): Explanation and Clinical Context The CT Pericardial Thickness Index (PTI) is a standardized measure of pericardial thickness adjusted for body surface area (BSA), providing a more individualized assessment of pericardial remodeling or constriction. Pericardial thickening >4 mm/m² is considered abnormal and may indicate constrictive pericarditis or risk for hemodynamic compromise.
