Article Synopsis
- * A total of 22 patients, primarily elderly males with a mean age of 71.7 years, underwent the LBBP procedure, achieving an 86% success rate in lead implantation without major complications.
- * The findings indicate that the Agilis HisPro™ catheter, paired with the Tendril STS Model 2088TC lead, is a promising and safe method for performing LBBP.
We report a case of epicardial ablation in a combined Brugada and inferior early repolarization syndrome patient with recurrent defibrillator therapy for spontaneous ventricular fibrillation. Electroanatomic mapping and ablation were achieved with remote magnetic navigation. Highly fractionated electrograms were seen epicardially in the anterior right ventricular outflow tract (RVOT) and at the anterior-inferior right ventricle.

- Remote Controlled Magnetic Navigation (RMN) for atrial fibrillation ablation reduces fluoroscopy time significantly compared to traditional Manual (MAN) techniques, but results in a longer overall procedural duration.
- In a study involving 214 RMN patients and 229 MAN patients, fluoroscopy times were shorter for RMN (53.5 min) while procedural times were longer (280.2 min), highlighting a trade-off between these two factors.
- Despite differences in timing, both techniques showed similar rates of acute procedural success (98.6% for RMN vs. 95.6% for MAN) and complication rates (2.3% for RMN vs. 4.8% for MAN), suggesting RMN is
A Mobitz type I block (Wenckebach phenomenon) with narrow QRS complex is almost always due to a lesion in the AV node. In a type I block with wide QRS complex (>0.12sec), the block can be in the His-Purkinje system in 60-70% of the cases.

Methods: Patients were followed up for six months with scheduled monthly remote monitoring transmissions in addition to routine in-office checks.
Pacemaker failure due to loss of fluid seal in a patient with a 5/6mm pacemaker header port and a 5mm unipolar lead.

Article Synopsis
- Before the standardization of pacemaker leads and connectors, connectors could accommodate both 5mm and 6mm lead pins, leading to potential issues with compatibility and durability.
- A patient with sick sinus syndrome had her original pacemaker replaced due to lead corrosion caused by blood leaks, highlighting the risks associated with the connector's design.
- To prevent complications, it is suggested to use sealing measures and consider re-implantation of the entire system instead of just replacing aging components.
A 48-year-old male patient underwent cardiac resynchronization therapy defibrillator implantation, and he was found to have atresia of the coronary sinus ostium with venous drainage occurring via a persistent left-sided superior vena cava, which was connected to the right-sided superior vena cava by the innominate vein. This is a rare benign cardiac anomaly that can pose problems when the coronary sinus needs to be cannulated. To identify the course of the coronary sinus, a coronary angiogram can be performed with attention directed to the venous phase of the angiogram.

Methods: The patient presented with pyrexia of unknown origin, and a contrast enhanced computed tomography aortogram revealed a large thrombus at the anterior aspect of the ascending aorta with two large ulcerations as a result of a chronic type A aortic dissection.
