Inge Edler

from Wikipedia, the free encyclopedia

Inge Gudmar Edler (born March 17, 1911 in Burlöv near Malmö; † March 7, 2001 ) was a Swedish cardiologist, professor in Lund. He was the founder of echocardiography in 1953 with the physicist Carl Hellmuth Hertz .

life and work

Edler graduated from Lund University in 1943 with a medical degree . From 1948 to 1950 he was head of the cardiac catheter laboratory at Lund University Hospital and then head of the cardiovascular laboratory. From 1953 until his retirement in 1977 he was head of cardiology in Lund.

At the beginning of the 1950s, he was responsible for the preoperative diagnosis of patients with heart valve defects and was dissatisfied with the existing diagnostic methods, especially for mitral stenosis . The mortality rates during operations were very high here, not least because of the poor diagnosis. Edler, who originally wanted to become a physics engineer, had a vague idea of ​​using radar or ultrasound technology and sought contact with the Lund physicist Carl Hellmuth Hertz, who had dealt with ultrasound diagnostics in materials research and had access to the appropriate equipment. First experiments with borrowed equipment (first by a company in Malmö that mainly worked for shipyards (Tekniska Roentgen-Centralen), then by Siemens in Erlangen) produced positive results in 1953. A first publication followed in 1954. This gave the impetus for the development of echocardiography, initially used by Edler in the diagnosis of heart valve defects. In cooperation with the group of cardiac surgeon Olle Dahlback, however, the use as a diagnostic instrument has been steadily expanded and in Lund it has also been extended to other areas of medicine such as the examination of pregnant women (Bertil Sunden, dissertation 1964).

Although several scientists in Lund familiarized themselves with the method (called by Edler and Hertz UCG, Ultrasound Cardiography) and began to develop it further in other countries (according to Sven Effert at the Helmholtz Institute in Aachen), the breakthrough did not come until the early 1960s with an extensive one Publication by Edler and Colleagues. Edler gave a lecture at the 3rd Congress of the European Society of Cardiology in Rome in 1960, followed by lectures by Edler in the USA, where the method was named echocardiography.

He was also involved in the further development of echocardiography, for example in the first simultaneous M-mode and Doppler recordings of the blood flow in the heart with Lindström in 1971.

In 1967 he received the Lasker ~ DeBakey Clinical Medical Research Award with Hertz . In 1997 he received the medal of the European Society of Cardiology and in 1983 the Rotterdam Echocardiography Award. In 1984 he received the Lund Prize from the Royal Physiological Society of Sweden and in 1987 the honorary professorship in Lund. He received the Munich and Aachen Prize for Technology and Applied Natural Sciences and in 1991 the Eric K. Fernströms Stora Nordiska Pris.

The German Society for Cardiology awards an Inge Edler research award to young scientists.
