“…Because of the anatomical difficulties and the high prevalence of complex arrhythmias in CHD patients, systematic planning of these procedures using electroanatomic navigation systems is recommended ( 2 , 42 , 44 , 56 ). Continuous technological advancements in navigation systems allow for better anatomical and substrate characterization, such as identifying surgical scars and areas of fibrosis.…”

“…However, treatment effectiveness is suboptimal, and despite therapeutic efforts, patients may experience recurrences and a tendency toward chronicity. The results of AF ablation in patients with complex CHD have been disappointing thus far, likely because the automatic activity of the pulmonary veins (typically addressed in conventional AF ablation) represents only a small part of its pathophysiology ( 44 ). AF appears in more advanced stages of the disease, with highly fibrotic and diseased atria.…”

The prevalence of congenital heart disease (CHD) in adult patients has risen with advances in diagnostic and surgical techniques. Surgical modifications and hemodynamic changes increase the susceptibility to arrhythmias, impacting morbidity and mortality rates, with arrhythmias being the leading cause of hospitalizations and sudden deaths. Patients with CHD commonly experience both supraventricular and ventricular arrhythmias, with each CHD type associated with different arrhythmia patterns. Macroreentrant atrial tachycardias, particularly cavotricuspid isthmus-dependent flutter, are frequently reported. Ventricular arrhythmias, including monomorphic ventricular tachycardia, are prevalent, especially in patients with surgical scars. Pharmacological therapy involves antiarrhythmic and anticoagulant drugs, though data are limited with potential adverse effects. Catheter ablation is preferred, demanding meticulous procedural planning due to anatomical complexity and vascular access challenges. Combining imaging techniques with electroanatomic navigation enhances outcomes. However, risk stratification for sudden death remains challenging due to anatomical variability. This article practically reviews the most common tachyarrhythmias, treatment options, and clinical management strategies for these patients.
