The first successful Norwood procedure involving the use of a cardiopulmonary bypass was reported by Dr. William Imon Norwood, Jr. and colleagues in 1981. [2] [3] Variations of the Norwood procedure, or Stage 1 palliation, have been proposed and adopted over the last 30 years; however, its basic components have remained unchanged.
A Sano shunt is a shunt from the right ventricle to the pulmonary circulation. [1] [2] [3]In contrast to a Blalock–Taussig shunt, circulation is primarily in systole. [citation needed]
William Imon Norwood Jr., also Bill Norwood (April 21, 1941 – December 13, 2020), was an American pediatric cardiac surgeon and physician. He was known for the Norwood procedure , a pioneering cardiac operation named after him for children born with Hypoplastic left heart syndrome .
Following the bidirectional Glenn shunt, failure of the procedure can be broadly categorized as failure of procedure, cardiac dysfunction related to surgery, or cardiac dysfunction leading to death before further surgical intervention. [8] Retrospective reviews demonstrate failure of the procedure in 6.5% of patients.
The Fontan Kreutzer procedure is used in pediatric patients who possess only a single functional ventricle, either due to lack of a heart valve (e.g. tricuspid or mitral atresia), an abnormality of the pumping ability of the heart (e.g. hypoplastic left heart syndrome or hypoplastic right heart syndrome), or a complex congenital heart disease where a bi-ventricular repair is impossible or ...
Radiograph images, before and after the procedure are used to evaluate the outcome of the treatment. The patients are scheduled to follow up at 3, 6, 9, and 12 months after the completion of therapy. The tooth is accessed for different aspects such as pain, swelling, sinus tract, mobility, tooth discoloration, and the occlusion relationship.
In dentistry, debridement refers to the removal by dental cleaning of accumulations of plaque and calculus (tartar) in order to maintain dental health. [1] Debridement may be performed using ultrasonic instruments, which fracture the calculus, thereby facilitating its removal, as well as hand tools, including periodontal scaler and curettes, or through the use of chemicals such as hydrogen ...
External cervical resorption is a localised resorptive lesion in the cervical area of the tooth, below the epithelial attachment. It is distinguished from external inflammatory root resorption in that it rarely involves the pulp. When at least 3 teeth are affected, it is referred to as multiple idiopathic cervical root resorption.
