Abstract
Background: Pulmonary atresia with intact ventricular septum (PA-IVS) is a rare condition, encompassing approximately 1%–3% of congenital heart diseases. Patients with PA-IVS have functional single-ventricle physiology. The ultimate possible outcomes for patients with PA-IVS are biventricular circulation, 1.5-ventricle or single-ventricle palliation, or cardiac transplantation. The bidirectional cavopulmonary shunt (BCPS) procedure directs flow from the superior vena cava into both the right and left pulmonary arteries, permitting flow to both lungs. The shunt is considered to be the second stage of palliation and is generally preparative for the third-stage Fontan procedure. The BCPS improves systemic arterial oxygen saturation without increasing ventricular work or pulmonary vascular resistance.Case: A 10-month-old, 25-day-old boy, weight 9.93 kg, body length 72 cm, diagnosed with PA-IVS, restricted persistent foramen ovale (PFO), right ventricle hypoplastic, and turtuous patent ductus arteriosus (PDA), underwent BCPS, atrial septectomy, and PDA stent evacuation surgery. The patient underwent a PDA stenting and ballooning atrial septectomy (BAS) at 17 days of age at the cathlab. The patient was cyanotic with stable hemodynamics and a saturation of 72% preoperatively.Discussion: Preoperative fasting must be observed to maintain the patient's hydration state. Pulmonary blood flow and systemic blood flow must be balanced. An adequate analgetic can prevent pain stimuli that increase pulmonary vascular resistance. Drugs to reduce the afterload, such as milrinone, are needed. Mechanical ventilation was set to get PaCO2 between 40 and 45 mmHg. Maintain the normal heart beat, preload, and contractility to maintain cardiac output (CO) with saturation 80–85%. Wean from mechanical ventilation as soon as possible.Conclusion: Anesthetic management for BCPS in patients with single ventricles from the preoperative period, intraoperative period, and postoperative period. Understanding single ventricle phsiology is important in order to treat the patient.
