It is estimated in 2018 there was an 85% for a survival rate of thirty years following a Fontan procedure and there are approximately 50,000 to 70,000 people in the world with Fontan circulation. [23] It is approximated that 40% of people with Fontan circulation are ≥18 years of age. [22]
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.

Currently, infants undergo either the staged reconstructive surgery (Norwood or Sano procedure within a few days of birth, Glenn or Hemi-Fontan procedure at 3 to 6 months of age, and the Fontan procedure at 1 1/2 to 5 years of age) or cardiac transplantation. [10] Current expectations are that 70% of those with HLHS may reach adulthood. [18]
An estimated annual 1,000 Fontan procedures are performed annually in the United States, with an estimated 50,000 to 70,000 patients having completed the procedure as of 2018. [14] [15] In Europe, an estimated 25,000 patients have completed the Fontan procedure as of 2021. [4]
SAS: The Kaplan–Meier estimator is implemented in the proc lifetest procedure. [17] R: the Kaplan–Meier estimator is available as part of the survival package. [18] [19] [20] Stata: the command sts returns the Kaplan–Meier estimator. [21] [22] Python: the lifelines and scikit-survival packages each include the Kaplan–Meier estimator ...
Survival rate is a part of survival analysis.It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy.
Perioperative mortality has been defined as any death, regardless of cause, occurring within 30 days after surgery in or out of the hospital. [1] Globally, 4.2 million people are estimated to die within 30 days of surgery each year. [2]
