Percutaneous patent foramen ovale (PFO) closure is performed for the prevention of paradoxical emboli. Doppler tissue imaging (DTI) was performed before and following transcatheter PFO closure in patients with an otherwise structurally normal heart to detect alterations in regional myocardial motion. The analysis revealed a mild, but statistically significant, reduction in the systolic motion of the basal interventricular septum. Other DTI parameters, including diastolic motion of the basal interventricular septum, systolic and diastolic motion of the left ventricular free-wall mitral annulus junction and the right ventricular free-wall tricuspid annulus junction, and the left ventricular cardiac performance (Tei) index remained unchanged. We found, thus, that transcatheter PFO closure does not cause major alteration in regional myocardial motion or cardiac performance.
经皮卵圆孔未闭（PFO）封堵术用于预防反常栓塞。对心脏结构正常的患者在经导管PFO封堵术前和术后进行多普勒组织成像（DTI），以检测局部心肌运动的变化。分析显示，心底室间隔的收缩运动有轻度但具有统计学意义的降低。其他DTI参数，包括心底室间隔的舒张运动、左心室游离壁二尖瓣环交界处和右心室游离壁三尖瓣环交界处的收缩和舒张运动，以及左心室心脏功能（Tei）指数均保持不变。因此，我们发现经导管PFO封堵术不会引起局部心肌运动或心脏功能的重大改变。
