目的

应用eSie Valves三维自动定量技术评估改良扩大Morrow术患者围术期主动脉根部相关参数,探讨其变化规律。

方法

选取2019年3月至9月于中国医学科学院阜外医院确诊为肥厚型梗阻性心肌病(HOCM),并进一步行改良扩大Morrow术的患者23例(HOCM组)和正常对照组23例。应用经食管三维超声心动图采集主动脉根部三维图像,eSie Valves三维自动定量分析系统重建主动脉根部三维模型,自动测量相关参数并进行组间比较分析。

结果

HOCM组患者术后梗阻部位厚度及左心室流出道压差较术前明显降低,差异均有统计学意义(P均<0.001)。所有患者术后二尖瓣反流量明显减少,与术前相比,差异有统计学意义(P<0.001);10例(43.5%,10/23)患者术后出现少量中心性主动脉瓣反流,其中4例为新发。HOCM组术前与正常对照组主动脉根部高度比较[(20.2±3.5)mm vs(23.5±1.8)mm],差异有统计学意义(P<0.05)。HOCM组术后较术前主动脉瓣缘对合高度减低[(11.7±1.3)mm vs(13.0±1.6)mm],差异有统计学意义(P<0.05),而主动脉根部高度增加,差异有统计学意义[(25.0±4.8)mm vs(20.2±3.5)mm,P<0.05]。

结论

HOCM患者存在主动脉根部结构部分异常,改良扩大Morrow术可以改善主动脉根部形态,eSie Valves三维自动定量技术可通过重建HOCM患者主动脉根部模型为其形态结构分析提供依据。

Objective

To evaluate the aortic root parameters of hypertrophic obstructive cardiomyopathy (HOCM) patients in the perioperative period of modified Morrow procedure with eSie Valves software to explore and analyze the change patterns and their causes.

Methods

Three-dimensional images of the aortic root were collected by transesophageal three-dimensional echocardiography (3D-TEE) from 23 HOCM patients in the perioperative period of modified Morrow procedure and 23 healthy volunteers (control group). The 3D model of the aortic root was reconstructed with the eSie Valves analysis system. Related parameters were automatically analyzed and compared.

Results

In the HOCM group, the thickness of the obstruction site and the pressure difference of left ventricular outflow tract were significantly lower than those before surgery (P<0.001). Postoperative mitral regurgitation was significantly reduced in all patients (P<0.001). A small amount of central aortic regurgitation occurred in 10 patients (43.5%, 10/23), 4 of whom were new. The preoperative height of the aortic root in the HOCM group was significantly lower than that of normal control group [(20.2±3.5) mm vs (23.5±1.8) mm, P<0.001]. In the HOCM group, compared with the preoperative data, the postoperative coaptation heights of the aortic valve decreased [(11.7±1.3) mm vs (13.0±1.6) mm, P<0.05], while the aortic root height increased [(25.0±4.8) mm vs (20.2±3.5) mm, P<0.05].

Conclusion

The eSie Valves 3D automatic quantitative analysis system can be used to reconstruct the aortic valve root model of HOCM, which reveals parts of the structural abnormalities of the aortic root. Modified Morrow procedure could improve the morphology of the aortic root.
