Study of 241 pediatric patients with pectus deformities found Marfan syndrome incidence of 5.3% (17-fold higher than general population) and cardiac anomalies in 35% overall. Combined-type pectus deformities showed highest Marfan association at 20%. Findings support routine cardiac and genetic evaluation for all patients presenting with pectus deformities.
