Acyanotic Shunt Lesions T2 Pediatric Practice: Cardiology YR 2012 FD 2012 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-176320-2 LK accesspediatrics.mhmedical.com/content.aspx?aid=56746325 RD 2024/03/28 AB Acyanotic cardiac defects are a group of diverse cardiac malformations that share a common physiology of increased pulmonary blood flow in the setting of normal systemic perfusion and oxygen saturation. Most of these defects produce varying degrees of shunting of blood from the left side of the heart to the right side. Patients with shunt lesions often present initially to the general pediatrician with problems ranging from failure to thrive and poor weight gain to respiratory distress and exercise intolerance. Alternatively, the patient may be asymptomatic but have an abnormal cardiovascular physical examination. Some of these defects, when left untreated, can affect long-term cardiovascular health. Therefore, this chapter will address the pathophysiology of shunt lesions, modes of presentation, indications for referral, and general treatment algorithms of shunt lesions.
