“…In the 1970s and 1980s, several surgical innovative procedures were introduced including Fontan surgery, creating a sustainable single-ventricle circulation, and the atrial redirection described by Senning and Mustard, followed by the Jatene or arterial-switch operation for transposition of the great arteries. 2 For children born with perhaps the most severe CHD, hypoplastic left heart syndrome, with Norwood surgery most such children could be offered a long-standing palliation, and the early Norwood hypoplastic left heart syndrome cases are today in their 30s. Many of these procedures were made possible through improved diagnostic procedures including echocardiography by the introduction of interventional catheterizations such as the Rashkind septostomy and by the ability to pharmacologically keep the ductus arteriosus open for prolonged periods of time.…”
