Hemodynamic Studies in Pectus Excavatum

Abstract

Hemodynamic data from 8 cases of mild to moderate pectus excavatum with presumptive diagnoses of organic heart disease were presented. A systolic thrill was described in 6 of the cases in addition to splitting of the pulmonary 2nd sound and parasternal systolic murmurs. No hemodynamic abnormalities were apparent on cardiac catheterization. These cases bring the total number of published cases with pectus excavatum similarly studied to 50 with only four showing evidence of heart disease. The production of ecg and auscultatory abnormalities in the absence of demonstrable cardiac pathology is ascribed to the unique chest wall configuration and its relationship to the heart. Emphasis is placed on cautious evaluation of the auscultatory findings in individuals with pectus excavatum.
