AI Article Synopsis
- Idiopathic third-degree AV block is rare, especially in younger patients, and can sometimes alternate with first- and second-degree blocks, as seen in a 39-year-old man.
- After thorough testing showed no clear underlying cause, a pacemaker was implanted to manage his fluctuating heart block conditions.
- The case emphasizes the potential genetic factors linked to AV block and introduces left bundle branch area pacing (LBBAP) as a promising new method for effective heart pacing.
Article Abstract
Idiopathic third-degree atrioventricular (AV) block in a relatively young patient is an uncommon phenomenon. Even more rare is when the third-degree heart block is alternating with the first- and second-degree AV blocks. In this case, we present a 39-year-old man with varying degrees of AV block, alternating the third-degree, second-degree, and first-degree AV blocks. The patient underwent an extensive workup for underlying etiologies, and results were inconclusive. A pacemaker was implanted and set for physiologic pacing via left bundle branch area pacing (LBBAP). This case will discuss potential genetic abnormalities associated with AV block and highlight LBBAP as an emerging technique for physiologic pacing.

Pectus excavatum (PE) can be associated with either congenital or acquired heart disease. This study highlights the importance of PE surgical repair in cases of severe chest depression on the heart in underlying cardiac diseases exacerbating cardiopulmonary impairment. From January 2023 to March 2024, four male patients underwent PE repair, having heart disease including pericarditis, mitral valve prolapse, ventricular fibrillation arrest and type 1 second-degree atrioventricular block.

Background: Cardiac resynchronization therapy (CRT) is an essential treatment for patients with symptomatic heart failure and ventricular conduction abnormalities. Low-ejection-fraction (EF) cardiomyopathy often involves a wide QRS complex displaying a left bundle branch block (LBBB) morphology and markedly delayed activation of the LV lateral wall. Following CRT, patients with heart failure and LBBB have better outcomes and quality-of-life improvements.

A physically active lifestyle offers multiple benefits, including lowering the risk of cardiovascular disease, lowering body-mass index (BMI), and, last but not least, improving the quality of life. However, there are still disincentives to physical activity in children with heart diseases due to the high protection of parents and the scarcity of data in the literature. The purpose of this paper is to help pediatricians and pediatric cardiologists identify the type of physical activity allowed in children with congenital cardiac malformations, thus minimizing the risk of major adverse effects, such as acute coronary syndrome and sudden cardiac death.

Typical atrial flutter (AFL), defined as cavotricuspid isthmus (CTI)-dependent macro-re-entrant atrial tachycardia, often causes debilitating symptoms, and is associated with increased incidence of atrial fibrillation, stroke, heart failure, and death. Typical AFL occurs in patients with atrial remodeling and shares risk factors with atrial fibrillation. It is also common in patients with a history of prior heart surgery or catheter ablation.

Considering the persistence of the AVB, it was decided to implant a permanent pacemaker. After considering all available options and the issues related to the patient, it was decided to implant a leadless pacemaker (LLP).
