Percutaneous occlusion of transseptal puncture‐related free wall perforation at the coronary sinus with a ventricular septal occluder during left atrial appendage closure: A case report

Abstract

Coronary sinus perforation is a life-threatening complication of transseptal puncture and needs to be repaired immediately. In this study, we report a case of a 74-year-old female patient with nonvalvular atrial fibrillation, who is a poor long-term anticoagulation candidate. During the manipulation of transseptal puncture, a perforation

Vital Role of Transesophageal Echocardiographic Surveillance of a Left Atrial Appendage Perforation Complicating Attempted Percutaneous Appendage Occlusion

“…7 Other reports have described the use of fluoroscopy to visualize contrast transit from cardiac chambers to the pericardium through a perforation. [8][9][10] However, to our knowledge, this report is the first to publish images of color Doppler identification and surveillance to resolution of active LAA-to-pericardial flow.…”

Case report: pulmonary artery perforation during transseptal puncture for left atrial appendage closure requires emergency cardiac operation

“…Several cases have been reported in which a percutaneous occluder was utilized to block aortic or cardiac perforations ( 12 , 7 ) during transseptal puncture. However, as cardiac tamponade can be life-threatening, emergency pericardiocentesis or surgical intervention appears to be the most promising therapeutic option to close the atrial leak ( 7 ).…”
