AVSD Surgical Mortality Score Calculator

AVSD Surgical Mortality Score: Explanation and Clinical Context The AVSD Surgical Mortality Score is a predictive tool to estimate the risk of operative mortality in patients undergoing repair for atrioventricular septal defect (AVSD). It incorporates key preoperative variables, including age, weight, presence of Down syndrome, preoperative ventricular dysfunction, and pulmonary hypertension. The score uses a logistic regression model to quantify mortality risk, providing clinicians with a probability percentage to inform perioperative planning and risk stratification.

This tool assists surgeons and cardiologists in preoperative counseling, surgical timing decisions, and identifying patients at higher risk who may require intensive perioperative management.
