More than 50 Years after Konno's Development of the Endomyocardial Biopsy

Abstract

The endomyocardial biopsy (EMB) method was first developed by Japan's Dr. Souji Konno in 1962. Since then, this technique has been used worldwide in clinical cardiology for the recognition and diagnosis of cardiomyopathies, arrhythmias, and other heart conditions. Many studies relating to the EMB have been published at the global level, including a large review by Cooper, et al.,(1)) wherein a limited selection of Japanese papers were cited despite considerable pioneering work on the EMB having been done in Japan. Following this, the Cardiac Biopsy Conference (CABIC) organization, which was founded in Japan in 1979, conducted a nationwide survey of the English language literature on the EMB. Among the collection of 500 studies compiled, approximately 40 abstracts have been selected by the co-editors in CABIC for further discussion. This report aims to supplement Cooper's work and bring to light other prominent contributions of Japanese researchers on the EMB.
