Implication

May offer non-invasive pulmonary hypertension assessment in mitral stenosis; correlation with catheterization data remains unconfirmed.

Key Points

Determine whether routine roentgenographic examination of the heart and lungs can reliably estimate pulmonary hypertension and hemodynamics in patients with mitral stenosis.
Studied 50 patients with rheumatic mitral stenosis (32 surgically confirmed) using multi-view chest roentgenography, esophagograms, and fluoroscopy.
Blinded roentgenologists evaluated changes in heart chambers, pulmonary artery size, hilar markings, and lung fields.
Conducted right heart catheterization to measure pulmonary capillary, arterial, ventricular, and atrial pressures, estimating pulmonary blood flow and vascular resistance.
Hemodynamic measurements were categorized by mean pulmonary artery pressure: normal/mildly elevated (<30 mm Hg), moderately elevated (30–49 mm Hg), and markedly elevated (>50 mm Hg).
Correlations between catheterization-derived pressures or vascular resistances and graded X-ray findings (normal, mild, moderate, marked) were graphically characterized.

Structured PICO

Does routine roentgenographic examination correlate with hemodynamic data obtained by right heart catheterization in patients with mitral stenosis?

Population

50 patients with rheumatic mitral stenosis of varying degrees of severity (32 confirmed at operation, 6 with atrial fibrillation, no clinical symptoms or signs of rheumatic activity).

Intervention

Roentgenographic examination including fluoroscopy, esophagograms, and postero-anterior, right anterior oblique, and left anterior oblique roentgenograms of the chest.

Comparator

Right heart catheterization to obtain hemodynamic data (pulmonary capillary, pulmonary artery, right ventricular, and right atrial pressures, pulmonary blood flow, and pulmonary vascular resistance).

Outcome

Relationship between roentgenographic findings (size and appearance of the pulmonary artery, lung fields, and heart chambers) and hemodynamic data.surrogate

This study outlines a methodology to determine if routine chest roentgenograms can accurately estimate the degree of pulmonary hypertension in patients with mitral stenosis, though specific results are not detailed in the abstract.
