Abstract 1. Antitachycardia pacemakers can be an important adjunct therapy in select patients with atrial arrhythmias unresponsive to medications, ablation, and surgery. It can reduce arrhythmia duration, arrhythmia burden, the…
Abstract 1. The presence of a prosthetic tricuspid valve is a relative but not absolute contraindication to endocardial pacing. 2. Epicardial pacing is a good option but does involve more…
Abstract 1. In patients with ACHD with AFib consider the possibility that IART can mimic AFib because of low-amplitude subtle P waves. 2. Patients with ACHD with AFib or IART…
Abstract 1. ACHD patients with systemic ventricular failure and a narrow QRS are not suitable candidates for biventricular pacing. 2. If biventricular pacing leads to poor response or clinical worsening,…
Abstract 1. While there is no limit to the number of ablations that can be performed in patients with complex atrial arrhythmias in the setting of a Fontan circulation, repeated…
Abstract In a patient with systemic ventricular dysfunction who has undergone atrial switch (Mustard/Senning operation) 1. Consider persistent or recurrent tachyarrhythmia as a potential cause of the ventricular dysfunction; 2….
Abstract 1. Patients with atrial switch (Mustard’s and Senning’s operations for transposition) and a combination of arrhythmias and systemic RV failure present extremely difficult management conundrums in adult congenital heart…
Abstract 1. In ACHD patients with atrial arrhythmias, the goal of treatment should always be rhythm control rather than rate control. 2. Catheter ablation is an excellent option for the…
Abstract 1. Severe RV or left ventricular dysfunction and sustained VT should be an indication for ICD placement in patients with severe forms of CHD. 2. Avoid placing pacing or…
Abstract 1. Whenever possible, use only MRI-compatible devices in patients with CHD. 2. CRT should be considered as an important therapeutic option in patients with systemic ventricular failure. 3. All…
