Abstract 1. Brady- and tachyarrhythmias frequently coexist in complex ACHD patients. Management of one can complicate management of the other. 2. All ACHD patients with intracardiac shunts and/or sluggish blood…
Abstract 1. Progressive or late-occurring bradyarrhythmias are an important cause of problems in ACHD. 2. “Symptoms” due to bradycardia can be vague and atypical. 3. All “symptomatic” bradycardia patients should…
Abstract 1. All patients with ACHD and AF, atrial flutter, or intraatrial reentrant tachycardia should undergo transthoracic and transesophageal echocardiography to rule out a thrombus prior to cardioversion. 2. In…
Abstract 1. Atrial switch (Mustard’s and Senning’s operation) patients can have complex plumbing and electrical issues. Proactive attention to both issues is important to reduce morbidity and mortality, to maintain…
Abstract 1. Periodic (?annual) rhythm monitoring with Holter or other monitors should be considered part of the management regimen in patients with complex ACHD. 2. In patients with intellectual or…
Abstract 1. Electrical causes of cardiac dysfunction include absence of AV synchrony, dyssynchronous ventricular activation, and tachycardia-induced cardiomyopathy. 2. Each of these three factors should be considered in any patient…
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,…
