Abstract:
Objective:To study the learning curve of percutaneous patent foramen ovale (PFO) occlusion guided solely by transthoracic echocardiography (TTE), as well as the success rate and safety of the learning curve.Methods:To retrospectively analyze these patients with indications for PFO occlusion admitted in our department from April 2021 to April 2022, and obtained 100 samples the author's initial cases guided solely by TTE, including 25 men and 75 women, with a mean age of (48.22±10.44) years old.Analyze preoperative baseline data: gender, age, height, weight, body mass index, the tunnel length and size of the PFO measured by transesophageal echocardiography, the grade of contrast-transcranial doppler test, combined atrial septal aneurysm, etc.Operation time, success rate, and complications were analyzed in all patients.Results:With the accumulation of cases, the operation time gradually shortened, accumulated to about 50 cases, the operation time has significantly shortened ( P<0.05), and the learning curve was leveled off after 50 cases ( P<0.05), there was statistical difference.The comparison of the success rate and complication of cases within the learning curve and those after completing the learning curve was no statistical significance( P>0.05). Conclusion:The learning curve of percutaneousc closure of patent foramen ovale guided solely by TTE is long, requiring about 50 cases to complete the learning curve. The success rate and safety of the learning curve are high. This procedure is worth popularizing.
