Jcalc2024 was held at the Tokyo Conference Center Shinagawa on January 19-20, 2024, and Yoshiaki Ito, Director of our hospital's Cardiovascular Center, served as the chairman.

In addition to lectures and hands-on sessions, the event also featured a live broadcast of PCI from our hospital on both the 19th and 20th.

A total of six patients with angina pectoris accompanied by calcification were treated over the two days. The surgeons were all directors of Jcalc, and included Dr. Shigeru Nakamura from Kyoto Katsura Hospital, Dr. Takashi Ashikaga from Musashino Red Cross Hospital, Dr. Gotoku Shibata from Miyazaki City and County Medical Association Hospital, Dr. Manabu Nakazawa from Kinki University, and Yoshiaki Ito from our hospital.

It appears that almost all of the devices for calcification currently available in Japan were used live, and although all cases were complex, treatment was successful in all cases without any major issues.

Many other experts also attended the lectures and other events, which I believe resulted in very meaningful discussions.

Next year's jcalc2025 will be held in Osaka, so we look forward to your cooperation and participation.

We would like to express our sincere gratitude to all those involved who participated.
