Pioneers in Cardiothoracic Surgery: Dr. René Favaloro

Posted by Susan Eymann, MS on Feb 16, 2017 12:00:00 PM

Dr. René Gerónimo Favaloro was an Argentine cardiac surgeon who pioneered coronary artery bypass surgery while at the Cleveland Clinic. He was born and raised in La Plata, capital of the province of Buenos Aires, Argentina to carpenter Juan B. Favaloro and Ida Y. Raffaelli, a dressmaker, both immigrants from Sicily, Italy.

Soon after completing his undergraduate degree in 1941, Favaloro was inducted into the Argentine army where he served for five years. In 1946, he left the service and continued his medical studies at La Universidad Nacional de La Plata, graduating in 1949. He would spend the next 12 years in a small farming community, La Pampa, as a rural physician. There, he educated patients about preventive medicine, established the first “mobile” blood bank in this area, and built his own operating room, where he trained general and surgical nurses. He later wrote about this period of his life in his book Memoirs of a Country Doctor.

Documentary ‘Who Shall Live’ Sets Healthcare Reform in Motion

Posted by Susan Eymann, MS on Nov 14, 2016 7:00:00 AM

A 1965 NBC documentary, "Who Shall Live?", narrated by Edwin Newman, created a stir. The documentary portrayed the highly controversial decision-making process that occurred during the early days of dialysis when only a few patients could be treated, and even then at great cost. The documentary showed faceless black silhouettes of the anonymous committee of community members against a stark white background as they deliberated over cases and selected which patients would receive dialysis treatment. Their decision meant life or death for the end-stage renal disease patients they were reviewing. The committee's authority was final and irrevocable. Ultimately, the serious ethical dilemma of a committee's choosing who would and wouldn't receive medical treatment to extend their lives set in motion a transformation of the healthcare system in this country.

The Maytag and Nose-Cone Artificial Kidneys

Posted by Susan Eymann, MS on Nov 7, 2016 7:00:00 AM

During the early days of dialysis, in the 1960s, only a few patients could be treated, and even then at great cost. This was unacceptable to W.J. Kolff, the inventor of the first artificial kidney.

As head of the Department of Artificial Organs at the Cleveland Clinic, Kolff wanted to make dialysis so reasonable that anyone could afford it. In his biography, Inventor for Life, The Story of W.J. Kolff, Father of Artificial Organs, Herman Broers relates how Kolff went in search of a way to allow kidney patients to dialyze at home to relieve the pressure of limited beds in dialysis centers. In 1966, Kolff and his team arrived at a solution.
