Key result
Commissurotomy linked to a reduced LA-LV diastolic pressure gradient in patients with mitral stenosis.
Why the study?
Simultaneous recording of pressure pulses in the left atrium, ventricle, and aorta was performed to simplify analysis of hemodynamic events in normal controls and mitral stenosis patients.
Observational
Demonstrates the feasibility of recording simultaneous pressure pulses from the left atrium, left ventricle, and aorta during surgery to analyze hemodynamic events.
Establishes foundational hemodynamic profiles for mitral stenosis; leaves open how these direct intraoperative pressure.
Pressure pulses from the human heart have been recorded at operation by simultaneous needle puncture of the left atrium, left ventricle and aorta. Superimposed tracings on equal ordinate scales were obtained, thus simplifying the analysis of hemodynamic events. Preliminary observations are presented from cardiologically normal controls and patients with mitral stenosis before and after commissurotomy.

Gordon et al. (1954) conducted an observational in Mitral stenosis and cardiologically normal controls. Simultaneous needle puncture of the left atrium, left ventricle and aorta was evaluated on Pressure pulses. Simultaneous needle puncture of the left atrium, left ventricle, and aorta allowed recording of superimposed pressure pulses in normal controls and patients with mitral stenosis.
