Right ventricular pressure dynamics after operation for pulmonary stenosis.
Right ventricular pressure dynamics were monitored during the first 24 hours after operation for relief of pulmonary stenosis in 9 patients with dysplastic pulmonary valves who underwent total valvectomy. Rather than the expected immediate drop in pressure after total removal of the obstruction, right ventricular pressures required 18 to 24 hours to decrease to physiological values. In 7 patients, the pressures decreased steadily, but in 2, there was an increase in pressure immediately postoperatively, followed by a gradual decrease.
