Patients with congenital heart disease and univentricular circulation are vulnerable to ventricular dysfunction. In the context of atrioventricular conduction defects, a ventricular pacemaker may be placed, possibly introducing dyssynchronous wall motion and deterioration of ventricular pump function. We describe such a case in which repositioning of the ventricular lead restored synchronicity.

BACKGROUND Pacemaker implantation serves as a prevalent therapeutic approach for bradycardia or atrioventricular blocks associated with syncope. While generally regarded as safe, this procedure is not devoid of rare yet severe complications. Examples include lead-induced cardiac perforation resulting in pneumothorax or pericardial effusion, which pose life-threatening risks.

Permanent pacemaker implantation is a low-risk procedure. However, complications may occur at a rate of around 4-8%. We present a case where initial implantation resulted in complications that could have been avoided by meticulous assessment of lead position in different projections and early post-procedure X-ray that would have delineated other serious complications.

Orbital complications are rare manifestations of congenital hydrocephalus. We present a case of a child presenting with unilateral exophthalmos and palpebral edema as a result of a chronic increased intracranial pressure and severe enlargement of the ventricular system. The initial presentation in our 13-year-old male patient was progressive right eyelid swelling.

Unlabelled: The intermuscular technique for subcutaneous implantable cardioverter-defibrillator (S-ICD) implantations is a technique for implanting the device between the anterior serratus muscle and latissimus dorsi (LD) muscle. A 70-year-old hypertrophic cardiomyopathy patient underwent a surgical repositioning of an S-ICD due to a moved device with skin thinning from mechanical stress. The patient had an S-ICD implantation 4 years prior to the reimplantation and the intermuscular technique was not expected to be achieved.

- - Persistent left superior vena cava (PLSVC) is a rare venous condition that can complicate medical procedures like central venous catheterization and pacemaker placement due to its atypical drainage patterns, which can sometimes lead to serious issues like hypoxia.
- - A case study involving a 64-year-old male with multiple health issues and atrial fibrillation highlighted the challenges of managing PLSVC during a dual-chamber pacemaker implantation, where the patient experienced lead displacement post-procedure.
- - PLSVC typically results from incomplete development of the left anterior cardinal vein and is often identified incidentally during procedures, emphasizing the need for careful navigation during cardiac interventions.
