We discuss the nursing intervention of nonstop minimally invasive tricuspid valve forming with simultaneous atrial flutter after secondary cardiac surgery. Patient is a 50-years-old male who undergoing repair of atrial septal defect by central thoracotomy with extracorporeal circulation as atrial septal defect in the 30 years ago require repair of atrial septal defect by central thoracotomy with extracorporeal circulation again as residual shunt after repair. In patient checking report of January 2019, it indicated that in the case of no obvious inducement patients appear palpitation, palpitation, is persistent. Base on admission dynamic electrocardiogram, it indicated: (1) Persistent atrial flutter (2) second degree atrioventricular block with junctional escape (3) severe tricuspid regurgitation. In result of operation, we successfully completed the operation, and the patient had no complications after the operation. The surgical procedure was to perform electrophysiological mapping of the right atrium, establish extracorporeal circulation, surgical bipolar radiofrequency ablation, and tricuspid valve formation. Base on result of this operation, effective implementation of prospective nursing interventions can reduce the risk of surgery. In addition, in operation process, as the operation involves a large number of instruments and equipment and surgical personnel, the position of equipment and the rationality of personnel station will influence the result of operation.
