Background: Left bundle branch area pacing (LBBAP) has gained increased adoption globally with the use of both lumenless leads (LLLs) and stylet-driven leads (SDLs). As these leads have been developed for conventional endocardial pacing sites, concerns remain regarding the lead integrity with LBBAP.
Objectives: This study evaluates lead integrity of pacing leads used for LBBAP in a large, real-world cohort of patients with LBBAP.
Article Synopsis
- A 74-year-old male with Kartagener's syndrome and permanent atrial fibrillation underwent successful cardiac resynchronization therapy (CRT) and atrioventricular node (AVN) ablation using remote magnetic navigation (RMN) through peripheral access.
- The patient had severe heart failure, a low ejection fraction of 30%, and significant complications from a left bundle branch block, leading to unsuccessful bi-ventricular pacing prior to the procedure.
- Post-ablation, the patient's bi-ventricular pacing efficiency improved to 100%, and there were notable improvements in both cardiac function and overall symptoms, highlighting the effectiveness of RMN-guided techniques in treating complex cardiac cases.
Article Synopsis
- The study aimed to develop a clinical scoring system to help doctors identify patients with suspected acute diverticulitis who might need further CT imaging to assess the severity of their condition.
- Researchers analyzed data from 513 patients diagnosed with CT-confirmed acute diverticulitis, finding key risk factors such as age, comorbidities, and certain lab results that increased the chances of complications.
- The resulting Acute Diverticulitis Severity Score effectively differentiates between uncomplicated and complicated cases, allowing for more targeted use of imaging, which can lower healthcare costs and improve patient care.
