AI Article Synopsis
- Sarcoidosis is a rare condition that can affect the heart, leading to various symptoms from mild issues to severe complications like heart failure and sudden death.
- A case was presented where a female patient experienced AV nodal re-entrant tachycardia, an unusual first sign of cardiac sarcoidosis, along with other heart rhythm disturbances.
- Awareness of the potential for rare presentations like supraventricular tachycardia is vital for early diagnosis, as it can help prevent sudden cardiac death, prompting the need for devices like implantable cardioverter-defibrillators for some patients.
Article Abstract
Background: Sarcoidosis is a rare disease, and cardiac involvement is seen in the minority of patients. The clinical symptoms depend on the location of the noncaseating granulomas in the heart and vary from asymptomatic to atrioventricular (AV) conduction block, ventricular arrhythmia, heart failure, and sudden cardiac death. Clinically manifest cardiac sarcoidosis seldomly presents with supraventricular tachycardia.
Case Summary: We present a case where a female patient presented with AV nodal re-entrant tachycardia as an uncommon initial presentation of cardiac sarcoidosis. Her resting electrocardiogram showed a complete left bundle branch block and first-degree AV conduction block. During hospitalization, there was continuous switching between sinus rhythm with first-degree AV block, 2:1 AV block, and AV nodal re-entrant tachycardia.
Discussion: It is important to be aware that cardiac sarcoidosis can rarely present with supraventricular tachycardia as initial symptom. Given the elevated risk of sudden cardiac death, early detection is crucial and all patients who require permanent pacing should be considered for implantable cardioverter-defibrillator implantation.

Background: Patients undergoing first-time atrial fibrillation (AF) ablation can benefit from targeting non-pulmonary vein (PV) triggers. Preprocedural identification of high-risk individuals can guide planning of ablation strategy. This study aimed to create a preprocedural screening tool to identify patients at risk of non-PV triggers during first-time AF ablation.

Background: Cardiac sarcoidosis involves a significant but difficult-to-define risk of sudden cardiac death (SCD). Current guidelines recommend consideration of an implantable cardioverter defibrillator for patients with extensive or significant myocardial late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging. However, extensive/significant LGE is not defined.

Giant cell myocarditis (GCM) and cardiac sarcoidosis share clinical and histologic features, but whether they represent separate processes or lie on an inflammatory cardiomyopathy spectrum is unclear. We present a case of cardiogenic shock thought to be secondary to biopsy-proven GCM with a subsequent post-transplant diagnosis of sarcoidosis through 18-fluorodeoxyglucose positron emission tomography and biopsy.

We report a unique case involving cardiac manifestation of T-cell lymphoma and associated risk management of ventricular arrhythmia and sudden cardiac death. A 39-year-old woman presented with a syndrome consistent with fever in a returned traveler, ultimately diagnosed with stage IV peripheral T-cell lymphoma involving the myocardium with ventricular tachycardia. Management of risk of sudden cardiac death was complicated by hematological management with an antibody-drug conjugate chemotherapy regimen and later autologous stem cell transplant.
