The following case series presents three different pediatric patients with SCN5A-related disease. In addition, family members are presented to demonstrate the variable penetrance that is commonly seen. Identifying features of this disease is important, because even in the very young, SCN5A disorders can cause lethal arrhythmias and sudden death.

Bidirectional ventricular tachycardia is a unique arrhythmia that can herald lethal arrhythmia syndromes. Using cases based on real patient stories, this article examines 3 different presentations to help clinicians learn the differential diagnosis associated with this condition. Each associated genetic disorder will be briefly discussed, and valuable tips for distinguishing them from each other will be provided.

The case series reviews differential diagnosis of a genetic arrhythmia syndrome when evaluating a patient with prolonged QTc. Making the correct diagnosis requires: detailed patient history, family history, and careful review of the electrocardiogram (ECG). Signs and symptoms and ECG characteristics can often help clinicians make the diagnosis before genetic testing results return. These skills can help clinicians make an accurate and timely diagnosis and prevent life-threatening events.

The epicardial outflow tract can be a site of origin of idiopathic ventricular arrhythmias. These arrhythmias are most commonly perivalvular and can be targeted from within the coronary venous system or from other adjacent structures, such as the right ventricular and left ventricular outflow tracts or the coronary cusp region. The authors report a case of an epicardial idiopathic outflow tract premature ventricular contraction originating from the midseptal epicardial left ventricle. In this case, direct epicardial access was crucial to identify early local activation and achieve successful catheter ablation...

A 70-year-old man with recurrent atrial fibrillation (AF) underwent transcatheter radiofrequency ablation after an earlier unsuccessful attempt. Although typical AF triggers were ablated, the patient's condition persisted, leading to the identification of the interatrial septum (IAS) as the probable source of the tachycardia trigger. Given the depth and thickness of the IAS, traditional radiofrequency ablation proved ineffective. However, using the alternative method of bipolar radiofrequency catheter ablation (B-RFCA), the atrial tachycardia was successfully terminated...

The left atrial appendage (LAA) is now recognized as a significant contributor to arrhythmia and thromboembolism in patients with a history of atrial fibrillation. Thoracoscopic exclusion of the LAA is made possible with the AtriClip device. In this report, we describe the case of a 65-year-old man with history of multiple left atrial ablation procedures and LAA clipping. He developed a microreentrant atrial tachycardia originating from the anterior base of the LAA stump, underwent complete isolation of the LAA, and had subsequent resolution of arrhythmogenic activity from the residual LAA stump...

A 34-year-old woman presented with palpitations and paroxysmal atrial fibrillation (AF). Workup revealed anterior mitral valve prolapse with severe mitral regurgitation. She was referred for surgical repair and underwent a mitral valve replacement, tricuspid valve repair, and bi-atrial cryoMAZE procedure with left atrial appendage ligation. Her postoperative course was complicated by inferior wall myocardial infarction. She subsequently presented with palpitations and underwent electrophysiology study and ablation...

A 69-year-old woman with a history of heart failure with reduced ejection fraction presented for device interrogation of her cardiac implantable electronic device (CIED), revealing lead and pulse generator displacement. Surprisingly, she exhibited a narrow QRS on the ECG despite an underlying right bundle branch block, suggesting unintentional conduction system pacing (CSP). Traditional cardiac resynchronization therapy has been widely used for patients with heart failure, but alternatives like CSP are emerging as viable options...

Cardiac implantable electronic device leads can contribute to tricuspid regurgitation and also complicate surgical and transcatheter interventions to manage tricuspid regurgitation. Here we present a case of a patient with sinus node dysfunction and complete heart block who underwent extraction of a right ventricular pacing lead before tricuspid valve surgery. We review the data regarding the contribution of leads to tricuspid regurgitation and the benefits of lead extraction, risks of jailing leads during tricuspid interventions, and pacing considerations around tricuspid valve procedures...

Leadless pacemaker systems (LPs) were developed as an alternative to traditional transvenous permanent pacemakers (TV-PPM) due to increasing rates of device and procedural related complications, leading to a high-cost burden to our health-care system. LPs were initially indicated for single-chamber ventricular pacing; however, recent developments have allowed for dual-chamber pacing too. These systems have demonstrated highly successful implant rates with stable pacing performance. This article describes the retrieval techniques of the Micra LPs and ways to mitigate challenges encountered during the retrieval process...

We present a complex case of cardiac implantable electronic device infection and extraction in the setting of bacteremia, large lead vegetation, and patent foramen ovale. Following a comprehensive preprocedural workup including transesophageal echocardiogram and computed tomography lead extraction protocol, in addition to the involvement of multiple subspecialties, an open chest approach to extraction was deemed a safer option for eradication of the patient's infection. Despite percutaneous techniques having evolved as the preferred extraction method during the last few decades, this case demonstrates the importance of a thorough evaluation at an experienced center to determine the need for open chest extraction...

This case report discusses a 42-year-old male with dextro-transposition of the great arteries (D-TGA) status post Mustard repair and sick sinus syndrome status post dual-chamber pacemaker implant, who developed symptomatic superior vena cava (SVC) baffle stenosis. He was treated with a combined pacemaker extraction and subsequent SVC baffle stenting. The case highlights the complexities of treating SVC baffle stenosis in the presence of cardiac implantable devices and demonstrates the efficacy of this combined approach...

Persistent left superior vena cava (PLSVC) is an anatomic variant that is relatively uncommon in the general population. Lead extraction through PLSVC is extremely rare. Due to unusual anatomy, the procedure carries challenges that require special considerations and careful planning. The authors report a case of lead extraction through a PLSVC with occluded right superior vena cava and highlight the challenges and outcomes of the procedure.

REVIEW

The population of patients with advanced heart failure continues to increase steadily as does the need for mechanical circulatory support. Combination therapy with left ventricular assist devices (LVADs) and cardiovascular implantable electronic devices (CIEDs) is unavoidable. CIED complications in patients with LVADs are common and often necessitate device system revision and transvenous lead extraction. Despite this, management recommendations are limited, and guidelines are lacking.

REVIEW

Transvenous laser lead extraction poses a risk of major complications (0.19%-1.8%), notably injury to the superior vena cava (SVC) in 0.19% to 0.96% of cases. Various factors contribute to SVC injury, which can be categorized as patient-related (such as female gender, low body mass index, diabetes, renal problems, anemia, and reduced ejection fraction), device-related (including the number, dwell time, and type of leads), or procedural-related (such as reason for extraction, venous obstructions, and bilateral lead placements)...

Tactical athletes are individuals in the military, law enforcement, and other professions whose occupations have significant physical fitness requirements coupled with the potential for exposure to life-threatening situations. Such exposures can have varied hemodynamic effects on the cardiovascular system. It is crucial that their clinical evaluation is inclusive of specific occupational requirements. Safety protocols regarding medical clearance are relatively more stringent for this population than for competitive athletes due to the increased impact to the tactical athlete, their team, and the population they aim to serve and protect should they experience a cardiovascular event on the job...
