Heart is a hollow muscular organ about the size of a fist. It is located behind the sternum, slightly to the left for most individuals.
The heartbeat is controlled by an internal pulse generator, called the sinus node. At rest, the pulse is normally between 60 and 90 beats per minute; it may be slower in well-trained athletes. The pulse quickens when strenuous exercise or acute stress situations. But If Heart Goes Wrong Life is at risk.
The first victorious heart transplant took place December 3, 1967 under the direction of Dr. Christiaan Barnard at Groote Schur Clinic in the City Cape Town of South Africa. It caused a sensation in the world. The patient, Louis Washanski, survived 18 days. The second patient shortly after surgery, still in South Africa, survived a year and a half.
Shortly after these two successes, other teams have tried to practice heart transplants. The first heart transplant includes conducted in Germany in February 1969; the patient survived 27 hours. The same year, the first attempts were made in Switzerland, but they were unsuccessful. It was only in 1985 in Zurich, we attended the first successful heart transplant in our country. Since heart transplantation has made great progress, and life expectancy of patients has increased dramatically. From 1986 to 2009, some 870 hearts were transplanted in Switzerland.
