CHD-Specific NYHA-like Class (Ross Classification) Calculator

CHD-Specific NYHA-like Class (Ross Classification): Explanation and Clinical Context The Ross Classification is a pediatric modification of the NYHA functional classification for patients with congenital heart disease (CHD). It stratifies patients based on symptom severity and limitation of physical activity. Class I indicates asymptomatic status, Class II denotes mild symptoms with ordinary activity, Class III reflects marked limitation with ordinary activity, and Class IV represents severe symptoms at rest or with minimal activity.

This classification provides clinicians with a practical tool for assessing functional status, guiding treatment decisions, and monitoring disease progression in pediatric and adult CHD populations.
