类癌性心脏病足类癌综合征临床和病理表现的一部份。其临床病理特征为:特殊纤维斑块累及三尖瓣和肺动脉瓣,限制瓣叶活动引起瓣膜的狭窄和返流。M型超声心动图可观察到严重类癌患者的三尖瓣及肺动脉瓣病变,但无特异性,不能评价其严重程度。而二维超声心动图(2—D echo)能确定心脏的解剖结构和瓣膜活动,因此它能很理想地用来分 Carcinoid heart disease foot cancer syndrome as part of the clinical and pathological manifestations. Its clinical and pathological features are: special fibrous plaque involving the tricuspid and pulmonary valve, limiting valve leaflets caused by valve stenosis and regurgitation. M-mode echocardiography can be observed in patients with severe carcinoid tricuspid valve and pulmonary valve disease, but no specificity, can not assess the severity. And 2-D echo can determine the anatomy and valve activity of the heart, so it can be used ideally
