Treatment involves destroying an abnormal circuit.<h2>What is catheter ablation?</h2><p>Catheter ablation is done in the cardiac (heart) catheterization laboratory to correct tachyarrhythmias.</p> <figure><span class="asset-image-title">Catheter ablation</span><img src="https://assets.aboutkidshealth.ca/akhassets/Catheter_ablation_MED_ILL_EN.jpg" alt="" /><figcaption class="asset-image-caption">Energy is delivered through a catheter inserted in the heart to eliminate an abnormal electrical pathway.</figcaption></figure> <h2>What are tachyarrhythmias?</h2><p>Tachyarrhythmias (say: tack-ee-a-RITH-me-uz) are fast (racing) heartbeats that are abnormal. These rapid heart rates are caused by abnormal electrical circuits in the heart. Sometimes these arrhythmias are treated with medication, and sometimes they need to be treated with catheter ablation.</p><h2>What is heart catheterization?</h2><p>During heart catheterization, the doctor carefully puts a long, thin tube called a catheter into a vein or artery in your child's neck or groin. The groin is the area at the top of the leg. Then, the catheter is threaded through the vein or artery to your child's heart.</p><p>The doctor who does the procedure is a cardiologist, which means a doctor who works on the heart and blood vessels.

Hot or cold temperature is used to destroy abnormal electrical circuits in the heart and correct the problem. </li> <li>There is a small risk that your child will have complications from the procedure. Your child's doctor will explain the risks to you before the procedure. </li> <li>Your child will need to have an anaesthetic. Your child will need to stay overnight in the hospital after the procedure. </li> <li>Your child will need to take <a href="/Article?contentid=77&language=English">ASA</a> to prevent blood clots after the procedure. </li> </ul><h2>What happens during the procedure</h2> <p>The procedure is performed while your child is under a general anaesthetic. This means that your child will be asleep during the procedure. </p> <h3>Finding the abnormal circuit</h3> <p>The doctor threads a special catheter through your child's blood vessels to the heart. A special type of X-ray called fluoroscopy lets the doctor see where the catheter is located. </p> <p>Electrical signals sent by the heart travel through the catheters. These signals give information about the heart's electrical system. The doctor also uses the catheters to trigger the rapid heart rate. This helps the doctor find the abnormal area in the heart. </p> <h3>Destroying the abnormal circuit</h3> <p>After the cardiologist finds the circuit that causes your child's heart to beat fast, they use hot or cold temperature to get rid of the circuit. When the circuit is destroyed, the rapid heart rate should not happen any more. </p> <h2>The procedure will take three to six hours</h2> <p>The procedure lasts three to six hours. After the procedure, your child will go to the recovery room to wake up from the anaesthetic. Then your child will go back to the inpatient unit. </p><h2>After the procedure</h2> <p>The cardiologist will let you know when your child can go home. Your child will probably need to stay in the hospital overnight after the procedure.

This feeling is normal. It is caused by single early beats that may have started the heart racing before the procedure. However, these events should no longer cause the heart to race. If your child does have a racing heartbeat, call the cardiologist. </p>

Ces pulsations rapides sont provoquées par des circuits électriques anormaux dans le cœur. Parfois des médicaments suffisent à traiter les arythmies et d'autres fois, elles doivent être traitées par une ablation par cathéter.</p> <h2>Qu'est-ce que le cathétérisme cardiaque?</h2> <p>Pour effectuer un cathétérisme cardiaque, le médecin place soigneusement un long petit tube appelé cathéter dans une veine ou une artère de votre enfant au niveau de son cou ou de son aine. L'aine désigne la région en haut de la jambe. Ensuite, le cathéter est enfilé dans la veine ou l'artère jusqu'au cœur de votre enfant. </p> <p>Le médecin qui effectue l'intervention est appelé un cardiologue, soit un médecin spécialiste du cœur et des vaisseaux sanguins. Il se peut qu'il ne s'agisse pas du cardiologue habituel de votre enfant.

Cela signifie qu'il dormira pendant l'intervention. </p> <h3>À la recherche du circuit anormal</h3> <p>Le médecin enfilera un cathéter spécial dans les vaisseaux sanguins de votre enfant, jusqu'à son cœur. Une fluoroscopie, un genre de radiographie, permet ensuite au médecin de voir où se situe le cathéter. </p> <p>Les signaux électriques émis par le cœur empruntent les cathéters. Ces signaux fournissent des renseignements sur le système électrique du cœur. Le médecin utilise aussi les cathéters pour déclencher les pulsations rapides du cœur. Ainsi, il peut trouver la région qui fonctionne anormalement dans le cœur.</p> <h3>Destruction du circuit anormal</h3> <p>Une fois que le cardiologue a trouvé le circuit problématique, il utilise de la chaleur ou du froid pour éliminer ce circuit. Une fois celui-ci détruit, les problèmes de pulsation rapide devraient être résolus. </p> <h2>L'intervention dure de 3 à 6 heures</h2> <p>L'intervention dure de 3 à 6 heures. Après l'intervention, votre enfant devra aller en salle de réveil en attendant de se réveiller après l'anesthésie. Ensuite, il sera reconduit à sa chambre. </p><h2>Après l'intervention</h2> <p>Le cardiologue vous indiquera le moment où votre enfant pourra retourner à la maison. Il devra probablement rester à l'hôpital au moins une nuit après l'intervention. Il devra peut-être aussi passer un échocardiogramme ou un test d'enregistrement de Holter avant de rentrer à la maison. Pour en savoir plus, veuillez consulter la rubrique « <a href="/Article?contentid=1214&language=French">Cathétérisation cardiaque: prendre soin de votre enfant après la procédure</a> »</p> <h3>Si le pouls de votre enfant s'emballe après l'intervention, appelez le cardiologue</h3> <p>Après l'ablation, les enfants ont souvent l'impression que leur pouls s'emballe. Cette sensation est normale. Elle provient de pulsations qui ont pu entraîner la pulsation rapide avant l'intervention. Toutefois, elles ne devraient plus entraîner un rythme cardiaque rapide. Si c'est cependant le cas et que le pouls de votre enfant s'emballe, appelez le cardiologue. </p>

To reduce this risk, we use a type of X-ray called fluoroscopy to see where the catheter is at all times. </p> <h3>There is a small risk of new heart rhythm problems</h3> <p>Sometimes the procedure can interfere with the heart's electrical system and cause new problems with the heartbeat.
