【摘要】：目的应用超声心动图研究不同分型二叶式主动脉瓣畸形(BAV)与主、肺动脉扩张的关系。方法回顾性分析我院经胸超声心动图诊断的382例BAV患者,按照Sievers′分型进行分组。另选取正常对照组200例。分别测量主动脉瓣瓣环、窦部、窦管结合部、升主动脉近端及主肺动脉近段内径。结果 382例BAV患者中,0型44例,1型338例,其中1(L-R)型226例、1(R-N)型97例、1(N-L)型15例。0型瓣环、窦管结合部、升主动脉及主肺动脉近段内径均较对照组增宽(P0.05),窦管结合部和升主动脉内径增宽显著(P0.01)。1型瓣环、窦部、窦管结合部、升主动脉及主肺动脉近段内径较对照组明显增宽(P0.01)。1型瓣环、窦部、窦管结合部内径较0型增宽(P0.05),窦部内径增宽明显(P0.01)。1(L-R)型较1(R-N)型窦部内径显著增宽(P0.01),1(N-L)型与其他两型窦部内径相比无差异(P0.05)。三型之间瓣环、窦管结合部、升主动脉及主肺动脉内径相比无差异(P0.05)。结论 BAV患者常伴有主动脉及肺动脉内径增宽。1型比0型BAV主动脉根部内径增宽。1(L-R)型在主动脉根部扩张显著。
[Abstract]:Objective to study the relationship between (BAV) and dilatation of main and pulmonary arteries in two-lobar aortic valve malformation with different classification by echocardiography. Methods A retrospective analysis of 382 patients with BAV diagnosed by transthoracic echocardiography in our hospital was carried out according to Sievers' classification. Another 200 cases of normal control group were selected. The inner diameters of aortic valve ring, sinus, sinus junction, proximal ascending aorta and proximal aortic artery were measured. Results among the 382 patients with BAV, 44 cases were of type 0 and 338 cases of type 1, including 226 cases of type 1 (L 眉 r), 97 cases of type 1 (RN), 15 cases of type 1 (N 渭 L) of valvular annulus and sinus junction. The inner diameter of ascending aorta and proximal segment of main pulmonary artery was significantly wider than that of control group (P0.05), and the internal diameter of sinus junction and ascending aorta was significantly widened (P0.01). Type 1 valvular annulus, sinus and sinus junction were significantly widened (P0.01). The diameter of ascending aorta and proximal segment of main pulmonary artery was significantly wider than that of control group (P0.01), and the inner diameter of type 1 valvular annulus, sinus and sinus junction was wider than that of 0 type (P0.05). The inner diameter of the sinus of type 1 (Lur) was significantly wider than that of type 1 (RN) (P0.01), and there was no difference between type 1 (N < 0 05) and the other two types (P 0 05), but the inner diameter of sinus of type 1 (n < 0 01) was significantly wider than that of type 1 (P 0 01). There was no significant difference in mitral annulus, sinus junction, ascending aorta and pulmonary artery diameter among the three types (P0.05). Conclusion the diameter of aorta and pulmonary artery in patients with BAV is much wider than that in type 0 BAV. The dilation of type 1 (L 眉 r) in the root of aorta is more significant than that of type 0 Aortic root.
