The purpose of this study is to assess the impact of coronavirus disease 2019 (COVID-19) on the performance of cardiovascular surgery in Japan. The information gathered may be useful to prepare for a surgery in Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) positive patients and prevent COVID-19 transmission from surgical patients to healthcare workers. [Methods] A web-based questionnaire was distributed to all accredited cardiovascular surgery centers in Japan. A total of 550 questionnaires were sent, and 310 (56.4%) were returned. [Results] Preoperative PCR or antigen testing was performed in all patients at 68.8% of centers. The proportion of surgeries postponed or cancelled was the highest for elective valvular and aortic surgeries and for emergency aortic surgeries. In most facilities elective surgeries were restricted to less than 50% of usual case volumes, while approximately 40% did not experience any negative impact on the case volume. Among the surgical patients, 32 were suspected to be SARS-CoV-2 positive, and 10 were confirmed. As preventive measures against spreading infection, more than 90% of the patients wore N95 masks, 33.3% full PPE, and 66.7% N95 mask+face shield. No case of patient-to-healthcare-worker transmission was reported. There were no postoperative deaths among the confirmed SARS-CoV-2 patients. [Conclusion] Restriction of surgical practice was placed on many institutions in the COVID-19 pandemic, but the degree of restrictions varied. Preoperative screening of all surgical patients and intraoperative use of PPE in those with suspected or confirmed SARS-CoV-2 infection adequately prevented transmission to healthcare workers. Since COVID-19 has a nationwide impact, it is important to continuously monitor surgical outcomes and infection rate by conducting perioperative surveys of COVID-19 patients.
