October 1, 1961Circulation

Four patients had normal pulmonary wedge and pulmonary artery pressures at rest with low cardiac index, while seven had normal cardiac index at rest and after mild exercise.

Overview

Variant hemodynamics in mitral stenosis warrant cautious resting assessment; leaves open independent flow regulation mechanisms.

Structured PICO

Population
11 cases of proved significant mitral stenosis with cardiovascular hemodynamic data (from a total group of 86)
O
Outcome
Hemodynamic patterns including pulmonary wedge pressure, pulmonary artery pressure, and cardiac index at rest and after mild exercisesurrogate

Patients with significant mitral stenosis can exhibit variant hemodynamic patterns, suggesting that flow-regulating factors can operate independently of the obstructive lesion.
