The left side of the heart can't be fixed, so the goal of the surgeries is to rebuild parts of the heart and "redirect" the way blood flows.</p> <p>After <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/norwood.html/">the Norwood procedure</a>, babies get the <strong>Glenn procedure</strong> when they're between 4 and 6 months old. This is because they outgrow the shunt placed during the Norwood procedure.</p> <p><img class="right" title="" src="https://kidshealth.org/EN/images/illustrations/HLHSglennEstab_415X415_enIL.jpg" alt="Illustration: A child with HLHS needs the Glenn Procedure because" /></p> <h3>What Is the Glenn Procedure?</h3> <p>The Glenn procedure is a type of <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/dictionary-open-heart.html/">open-heart surgery</a>. The goals are to:</p> <ul class="kh_longline_list"> <li>Make <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/blood.html/">blood</a> from the upper part of the body (the head, neck, and arms) go directly to the <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/lungs.html/">lungs</a>. This lets the blood pick up oxygen without passing through the heart.</li> <li>Take some of the extra work away from the <a class="kh_anchor">right ventricle</a>. Until now, the right ventricle has been doing two jobs: pumping blood to the lungs <em>and</em> to the body.</li> </ul> <h3>What Happens During the Glenn Procedure?</h3> <p>The Glenn procedure redirects blood flow from the upper body to the lungs. In the Glenn procedure:</p> <ol class="kh_longline_list"> <li>The <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/dictionary-svc.html/">superior vena cava (SVC)</a>&nbsp;(which brings blood back from the upper part of the body) is disconnected from the heart and connected directly to the <a class="kh_anchor">pulmonary artery</a>.</li> <li>The <a class="kh_anchor">shunt</a> placed during the Norwood procedure is removed.<img class="right" title="" src="https://kidshealth.org/EN/images/illustrations/HLHSglenn_415X415_enIL.jpg" alt="Illustration: During the Glenn Procedure" /></li> </ol> <p>Blood from the upper body now goes to the pulmonary artery, and then to the lungs, without having to go to the heart. Because blood can now get to the lungs, the shunt is no longer needed. Also, the right ventricle now has a single job: pumping blood to the body.</p> <p><img class="right" title="" src="https://kidshealth.org/EN/images/illustrations/HLHSglennBloodflow_415X415_enIL.jpg" alt="Illustration: How blood flows after the Glenn Procedure" /></p> <h3>What Happens After the Glenn Procedure?</h3> <p>Babies who have the Glenn procedure usually spend 1 to 2 weeks in the hospital to recover. They get-around-the-clock care and monitoring. They also get medicines to help the heart and improve blood flow.</p> <h3>What's the Next Procedure?</h3> <p>The third surgery is called the <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/fontan.html/"><strong>Fontan procedure</strong></a>. It's usually done when a child is 18 to 36 months (3 years) of age.</p>Cirugía correctora del síndrome de corazón izquierdo hipoplásico: el procedimiento de GlennEl procedimiento de Glenn es un tipo de cirugía a corazón abierto.https://kidshealth.org/ws/RadyChildrens/es/parents/glenn-es.html/6f5fd4bd-5fda-424a-a82c-fd3be5ed338a
