The Basic Lecture Course (BLC) hands-on seminar has long been a core educational activity organized by the U-40 of the Japanese Society for Cardiovascular Surgery at the branch level. However, due to the COVID-19 pandemic, in-person seminars were suspended for an extended period. Since 2022, the seminars have gradually resumed, and in 2025, a branch-based hosting system was introduced. Nevertheless, several challenges unique to the post-pandemic era have become evident. In the Hokkaido Branch, BLC hands-on seminars were held in July 2024 and August 2025. This report presents the outlines and management processes of these two events, summarizes the results of participant surveys, and discusses future challenges and perspectives for the operation of BLC hands-on seminars.

We present a successful case of redo-tricuspid valve replacement for tricuspid prosthetic valve endocarditis. A 78-year-old man who underwent tricuspid bioprosthetic valve replacement for severe tricuspid regurgitation thirty-two years earlier was referred to our institution with persistent high fever and back pain. The blood culture was positive for Streptococcus oralis, and echocardiography revealed a mobile vegetation attached to the tricuspid prosthetic valve with moderate tricuspid regurgitation. A clinical diagnosis of prosthetic valve endocarditis was established. Redo-tricuspid bioprosthetic valve replacement was performed following antibiotics therapy. The patient was discharged on postoperative day 49 after 6 weeks of additional antibiotic treatment, and had no recurrence of infection for 6 months after redo-surgery.

Lately, there has been a trend towards integration among cardiovascular surgery institutions. However, local institutions continue to play a crucial role in community-based medicine, given the emergent nature of cardiovascular diseases and the challenges involved in transporting patients with such conditions over long distances. We present the results of a questionnaire survey we conducted to examine the current status and issues faced by cardiovascular surgery institutions in community-based medicine.
