Alcohol septal ablation was first performed in 1994 by Ulrich Sigwart at the Royal Brompton Hospital in the United Kingdom. [2] Since that time, it has gained favor among physicians and patients due to its minimally invasive nature, thereby avoiding general anesthesia, lengthy inpatient recuperation and other complications associated with open-heart surgery (e.g. septal myectomy).
This surgery had not been possible prior to 1975 because of difficulty with re-implanting coronary arteries which perfuse the actual heart muscle itself , and even after it was first performed the excellent results from the Mustard operation meant that it was a long time before the Jatene procedure took over.
Ordinarily, septal myectomies are performed only after attempts at treatment with medication fail. The choice between septal myectomy and alcohol ablation is a complex medical decision. [citation needed] Septal myectomy was established by Andrew G. Morrow in the 1960s. [3]
When performed properly, an alcohol septal ablation induces a controlled heart attack, in which the portion of the interventricular septum that involves the left ventricular outflow tract is infarcted and will contract into a scar. There is debate over which people are best served by surgical myectomy, alcohol septal ablation, or medical therapy.
Srihari S. Naidu is an American physician and Professor of Medicine at New York Medical College who is known for his work on hypertrophic cardiomyopathy including the procedure known as alcohol septal ablation, and for helping to construct the universal diagnostic criteria for cardiogenic shock.
Arterial switch operation (ASO) or arterial switch, is an open heart surgical procedure used to correct dextro-transposition of the great arteries (d-TGA). [1] [2]Its development was pioneered by Canadian cardiac surgeon William Mustard and it was named for Brazilian cardiac surgeon Adib Jatene, who was the first to use it successfully.
The first U.S. cases of AIDS emerged in 1981, though health officials at the time didn't yet fully understand the disease or its implications. It was first identified as a "gay cancer" as it ...
It will contract midline with the umbilicus. It begins its contractions and by twelve hours after the birth it can be felt to be at the level of the umbilicus. [9] The uterus changes in size from one kilogram to 60-80 grams in the space of six weeks. After birth, the fundus contracts downward into the pelvis one centimeter each day.
