A Difficult Diagnosis in the Presence of Atrial Fibrillation
The present report concerns ten patients with significant tricuspid stenosis and atrial fibrillation. The diagnosis could be made clinically in only two patients and by pullback record from right ventricle to right atrium in three, including the two mentioned previously. Careful hemodynamic assessment of tricuspid valve function by using simultaneously recorded right atrial and right ventricular pressures resulted in the detection of significant tricuspid stenosis in the nine patients on whom these measurements were made. The influence of atrial fibrillation and respiration on the tricuspid gradient and the role of exercise and amyl nitrite in augmenting barely detectable resting gradients are demonstrated.
