Edler, known as the ‘Father of Echocardiography’
Edler, known as the ‘Father of Echocardiography’, identified a moving signal with cardiac motion.4 Then after, this technique was used for the evaluation of mitral stenosis. Their first paper entitled, ‘The Use of Ultrasonic Reflectoscope for Continuous Movements of the Heart Wall’ was published in 1954.5 In 1969, Edler introduced the combined use of Doppler and echocardiography as an approach to diagnose aortic and mitral regurgitation.6 Japanese investigators were the first to work on Doppler technology.7,8 For the first time the detection of pericardial effusion with ultrasound was reported by Harvey Feigenbaum and colleagues in 1965.9
The development of the M-mode technique for measuring left ventricular dimensions was introduced by Feigenbaum and Dodge In 1968.10 Eventually, echocardiography was recognized as a perfect diagnostic technique, and after 1970, echocardiography were assigned in all annual meetings of the American College of Cardiology.11 “The first academic course dedicated to cardiac ultrasound was learnt in Indianapolis in 1968 and the first book on echocardiography published
