Annual Report for 2019 by the Japanese Association for Coronary Artery Surgery

Purpose: Continuous annual reporting on coronary artery bypass grafting (CABG) surgical practice is key for quality control and improvement of clinical results. In this report, Japanese nationwide features and trends in the extent of coronary artery disease and the characteristics of those undergoing CABG procedures in 2019 are presented. Clinical results of related ischemic heart disease are also presented.Methods and Results: The Japanese Cardiovascular Surgery Database (JCVSD) is a nationwide surgical case registry system. Data regarding CABG cases in the year 2019 (1 January-31 December) were captured with questionnaires regularly administered by the Japanese Association for Coronary Artery Surgery (JACAS). We analyzed trends in the number and types of grafts selected according to the number of diseased vessels in patients undergoing CABG. We also analyzed descriptive clinical results of those undergoing surgery for acute myocardial infarction or ischemic mitral regurgitation. Conclusions: This is the second publication summarizing the results following the JACAS annual report based on JCVSD Registry data from the year 2019. Clinical outcomes and surgical strategy trends were relatively stable. Further accumulation of information with a similar data collection system is expected.
