There is an increased risk of cardiac complications in COVID-19 among patients with pre-existing comorbidities due to their existing pro-inflammatory status. The manifestation of complete heart block has been evidenced as transient and in no need of intervention. This case presents a previously healthy woman who was diagnosed with SARS-CoV-2 infection and complete heart block; she underwent permanent dual-chamber pacemaker implantation after successful treatment and a negative COVID-19 test.

Background: Transvenous lead extraction (TLE) has become an essential component of lead management strategies, but it carries the risk of severe complications, including damage to the tricuspid valve. Currently, there are no established predictors that can help prevent these complications.
Case Summary: An 84-year-old male with a dual-chamber pacemaker was admitted to the hospital due to a pocket fistula resulting from a local infection.

Background: The use of single-chamber, right ventricular (RV) leadless pacemakers (LPs) has been well established, the introduction of a right atrial LPs has opened the door for dual-chamber leadless pacing. Cardiac computed tomography (CT) segmentation integration might provide proper visual guide during the procedure.
Case Summary: A 58-year-old male patient was brought to the emergency department with dizziness and complete heart block.

An infant with DiGeorge syndrome, multiple comorbidities, and truncus arteriosus type II underwent repair complicated by heart block necessitating placement of a dual-chamber bipolar pacing system with right ventricular leads and subsequent resynchronization with placement of left ventricular apical pacing leads. Resynchronization therapy improved QRS duration from 180 ms to 100 ms and ejection fraction from 25% to 54% over the course of 4 weeks with gradual return to normal function and eventual discharge.

Right ventricular pacing is an effective and safe treatment option for patients experiencing symptomatic bradycardia. However, some individuals may develop left ventricular dysfunction as a consequence. Growth differentiation factor 15 (GDF-15), which is not present in a healthy adult heart, is upregulated in cardiomyocytes in response to various stress stimuli.
