Welcome to the 22nd Annual Meeting of Japanese Society for Adult Congenital Heart Disease         It is my great pleasure to inform you that the 22nd Annual Meeting of the Japanese Society for Adult Congenital Heart Disease (ACHD) will be held from January 17 to January 19, 2020, at the Tokyo Conference Center, Ariake in Tokyo, Japan.       The annual meeting of the Japanese Society for ACHD is the most prestigious conference on adult congenital heart disease in Japan, and it is organized by faculty members from the Japanese Society of Cardiology, Pediatric Cardiology, Cardiovascular Surgery, and Obstetrics and Gynecology. We expect approximately 800 participants at the next annual meeting. The main theme of the 2020 meeting will be Professionalism and Harmony for Comprehensive ACHD Management, which will focus on the refinement of multidisciplinary patient care, as based on a well-organized collaboration of experts in all affiliated sub-specialties.       For this purpose, we have scheduled multiple joint symposiums, incorporated with the committees of other Japanese societies (e.g., the Japanese Society for Cardiology, Cardiovascular Surgery and Extracorporeal Technology) to exchange and augment the expertise and skill via a deep comprehensive discussion, and we will also feature a collaborative session of a “multi-professional conference,” composed of various types of in-hospital staff for discussing patient management systems, social security, socialization, pregnancy and delivery, and mental issues for ACHD patients.       In 2020, the Tokyo Olympic Year, we have invited many distinguished guest speakers, such as Dr. Duke E. Cameron, MD, PhD from Massachusetts General Hospital, Dr. Massimo Chessa MD, PhD from San Donato, University Hospital, Italy, Dr. Margarita Brida, MD, PhD from University Hospital Centre Zagreb, Croatia, Dr. Pedro del Nido MD, PhD from Boston Children’s Hospital, Boston, Dr. Erwin Oechslin, MD, PhD from Toronto, Canada, Dr. Eun-Jung Bae MD, PhD from Seoul National University College of Medicine, Korea, Dr. Gi Beom Kim MD, PhD from Seoul National University Children's Hospital, Korea, Dr.Yiu-fai Cheung MD, PhD from The University of Hong Kong, Hong Kong, Dr. Geetha Kandavello MD, PhD from Institute Jantung Negara, Kuala Lumpur, Malaysia, and Dr. Lucy Y Eun MD, PhD from Yonsei University College of Medicine, Seoul, South Korea.       As the president of this congress, I would like to extend my warmest wishes in officially inviting you to attending to the congress, and I sincerely believe that your participation will contribute significantly to the success of this congress.       We are very looking forward to seeing you at the venue in Tokyo.       All the best, Kiyozo       Kiyozo Morita MD President of the 22nd Annual Meeting of the Japanese Society for Adult Congenital Heart Disease Professor, Pediatric Cardiovascular Surgery, Jikei University School of Medicine Tokyo, Japan 3-19-18 Nishishinbashi, Minato-ku Tokyo 105-8461 81-33433-1111 ext 3509 kiyozo@jikei.ac.jp   Management Secretariat c/o Procomu International, Inc, 3-6-11 TFT eat 9Fr, Ariake, Koutou-ku, 125-0063, Japan Tel +81-3-5520-8821 Fax +81-3-5520-8820 E-mail: jsachd22@procomu.jp
