T he Pitié-Salpêtrière Hospital in Paris, France, has a long distinguished history. It was the birthplace of neu- rology and heart transplantation in Europe, and today it women of easy virtue. In 1684, a prison was established in the Salpêtrière for female prisoners and prostitutes. This prison was used until the French Revolution. “Interestingly continues to be a centre of expertise in these areas as well there is a very curious church inside my hospital with several as in oncology. “My hospital was the place where neurology rooms and several altars,” Professor Komajda reveals. “The was born—Charcot worked here during the 19th century reason for this is that they wanted to separate men from and he is the pioneer of the specialty,” explains Professor women who were in jail when they were going to mass, so Michel Komajda, MD, president-elect of the European the architecture of the chapel is absolutely unique because Society of Cardiology and head of the Department of we have 4 or 5 different altars in 1 single church.” Cardiology at Pitié-Salpêtrière Hospital. “It is also where The 2 hospitals became 1 institution in the 1960s and now cardiac transplantation was born in Europe.
