Ambler Score: Explanation and Clinical Context Ambler Score is a validated risk prediction model for estimating 30-day mortality after cardiac surgery, including CABG, valve procedures, and combined operations. It uses multiple preoperative patient characteristics, cardiac function parameters, and operation-related factors to calculate a probability of death using logistic regression. This tool allows clinicians to i
Aortic Valve Area by Continuity Equation: Explanation and Clinical Context Aortic valve area is a fundamental parameter used to assess the severity of aortic stenosis. The continuity equation is the most widely endorsed method for calculating aortic valve area because it is grounded in the principle of conservation of mass. According to this principle, flow in the left ventricular outflow tract must equal flow across
