| Popis: | Pulmonary wedge angiograms (PWA) were analyzed qualitatively and quantitatively to evaluate the pulmonary vascular bed in 40 patients with congenital heart disease. The patients were divided into four groups: group 1, normal pulmonary hemodynamics; group 2, increased pulmonary blood flow; group 3, pulmonary hypertension (PH); and group 4, PH with elevated pulmonary vascular resistance. The PWA were analyzed for tapering, pulmonary circulation time (PCT) index, and vascular image. The tapering was normal in groups 1 and 2 and was more rapid in groups 3 and 4. The PCT index was slightly lower in groups 3 and 4 than in groups 1 and 2. With 100% oxygen, the tapering became less severe and the PCT index increased in group 3. However in group 4, these parameters did not improve with 100% oxygen, suggesting that more advanced vascular changes had developed. These studies confirm the usefulness of the PWA in evaluating the pulmonary vascular bed of patients with congenital heart disease and PH. |
