Objective To explore the experience of participating the preoperative visit in patients undergoing percutaneous coronary intervention（PCI）. Methods Semi-structured interviews were carried out from July to August 2021. Ten patients who participated in the preoperative visit were recruited. Data were analyzed by Colaizzi’s method. Results The interviews lasted for about 330 minutes and approximately 18，000 words were transcribed. Four themes emerged from the data：negative emotions were relieved（less fear，less nervousness），knowledge and attitude were changed（understanding the PCI process，understanding environmental information，actively cooperate in PCI process），access to humane nursing services（patience and carefulness，thoroughness），unmet needs （communication methods need to be improved，being eager for positive support and care，multiple forms of visits）. Conclusion Patients could relieve negative emotions，correctly understand and actively confront the PCI through preoperative visit，and make them feel care and warmth. However，there are still difficulties in language communication and positive support. Nursing managers should strengthen the training of nurses in cardiac catheterization room，improve the preoperative visit，to meet patients’ physiological and psychological demands，improve the satisfaction level with the preoperative visit.
