Application value of echocardiography in minimally invasive thoracoscopic mitral valvuloplasty during perioperative period

Abstract

Objective This study retrospectively analysed patients undergoing thoracoscopic mitral valvuloplasty in our hospital from 2019 to 2020 and discussed the value of echocardiography (including three-dimensional transoesophageal echocardiography and transthoracic echocardiography) in the perioperative period. Methods In the Department of Cardiothoracic Surgery of our hospital, 57 patients needing surgical treatment were screened by echocardiography. Ultrasonography was performed preoperatively (G1) and 1 week (G2) and 3 months (G3) postoperatively for each patient. The doctor recorded the left atrial anteroposterior diameter (LAD), left ventricular anteroposterior diameter (LVD), mitral orifice velocity (MV), mitral pressure of gradient (MVG), and ejection fraction (EF), which were used to observe and compare the left heart reconstruction and mitral valve repair to provide an imaging basis for clinicians to choose the most appropriate valve model. Transoesophageal echocardiography was also performed preoperatively to provide an imaging basis for clinicians to choose the most appropriate valve model. Results The results from the three ultrasound examinations showed statistically significant differences among EF, LAD, and LVD. The intraoperative transoesophageal ultrasound measurement of the mitral regurgitation area (S2, 9.57 ± 1.47) was greater than the preoperative transthoracic ultrasound measurement of the mitral regurgitation area (S1, 8.83 ± 2.01), and the difference was statistically significant (p < 0.05). Conclusions 3D-transoesophageal echocardiography is a convincing imaging examination that can assist cardiologists in formulating the most appropriate surgical plan. Transthoracic echocardiography (TTE) is less invasive and easier to operate compared to transoesophageal echocardiography (TEE). The use of perioperative TTE can help detect new heart conditions in emergency and surgical patients in a timely manner and determine the factors that cause hemodynamic instability, which has a positive effect on the perioperative management of such patients.
