      Abstract

      Described herein are intracardiac sound and pressure events recorded in 105 patients with organic heart disease by means of an intracardiac micromanometer at right heart catheterization. Sound-pressure relationships are defined in patients with selected congenital and acquired cardiac diseases. Pressure pulse recordings of high quality with simultaneous isolation and localization of specific sound events provide investigative and diagnostic information. Renewal of interest in the origin, transmission and clinical correlation of the classic auscultatory events are accompaniments of intracardiac sound-pressure studies.
