Post-Cardiac Injury Syndrome Following Permanent Pacemaker Implantation Presenting Exclusively As Massive Pleural Effusion: A Rare Occurrence.

Post-Cardiac Injury Syndrome (PCIS) akin to Dressler's syndrome is late-onset pericarditis that is triggered by the body's immune system and presents commonly as pleuro- pericardial symptoms and raised inflammatory markers. Its occurrence following the insertion of a pacemaker has been reported infrequently and varies in different studies with an estimated prevalence of 1-2%. Our case reports a unique incidence of isolated pleural effusion following the implantation of a pacemaker in a 62-year-old female with complete heart block with no evidence of pericardial effusion on imaging.

Accessory Cardiac Conduction Pathway with an Unusual Presentation.

Pre-excitation syndrome (PES) is a congenital abnormality in which there is conduction through accessory pathway in addition to atrioventricular (AV) node between the atria and the ventricles. Conduction through accessory pathway is without any delay and; hence, results in early excitation of ventricles. This dual connection provides substrate for atrioventricular reciprocating tachycardia (AVRT), a type of supra-ventricular tachycardia.

Persistent left superior vena cava: A disconcerting finding for interventionist.

Persistent left superior vena cava (PLSVC) is one of the commonest venous anomalies of thoracic venous system. These cases usually have normal right sided superior vena cava (SVC). Patients with PLSVC are often asymptomatic hence, it is diagnosed as an incidental finding during procedures like central venous line placement or pacemaker implantation.
