We reviewed the M-mode and two-dimensional echocardiograms of 100 consecutive patients with rheumatic heart disease. All were subsequently studied by cardiac catheterization and angiography. In four patients, cardiac catheterization showed tricuspid stenosis (average mean diastolic gradient 6.2 mm Hg), which was confirmed during cardiac surgery. M-mode echocardiography showed a diminished EF slope in 12 patients (mean 26 mm/sec), including the four patients with tricuspid stenosis. Seven of the eight patients without tricuspid stenosis had significant pulmonary hypertension; the reasons for the diminished EF slope in the other patient could not be identified. Tricuspid stenosis was diagnosed in four patients from two-dimensional echocardiograms on the basis of diastolic doming and restricted leaflet motion of the tricuspid valve. These four patients were the same patients in whom tricuspid stenosis was diagnosed by cardiac catheterization. We conclude that two-dimensional echocardiography is useful in the diagnosis of tricuspid stenosis.
我们回顾了连续100例风湿性心脏病患者的M型和二维超声心动图。所有患者随后均接受了心导管检查和血管造影。4例患者心导管检查显示三尖瓣狭窄（平均舒张期平均压差6.2 mmHg），心脏手术时得以证实。M型超声心动图显示12例患者（平均26 mm/秒）的EF斜率降低，其中包括4例三尖瓣狭窄患者。8例无三尖瓣狭窄的患者中有7例有明显的肺动脉高压；另一例EF斜率降低的原因不明。根据二维超声心动图上三尖瓣舒张期圆顶状改变和瓣叶运动受限，4例患者被诊断为三尖瓣狭窄。这4例患者与心导管检查诊断为三尖瓣狭窄的患者相同。我们得出结论，二维超声心动图对三尖瓣狭窄的诊断有用。
