Coronary artery complications with left bundle branch area pacing: A review of literature.

Left bundle branch area pacing (LBBAP) is an emerging technique in cardiac resynchronization therapy that shows promise in improving ventricular synchrony and clinical outcomes in patients with heart failure. However, the potential risk of coronary artery complications with LBBAP necessitates careful attention and management. This literature review explores the mechanisms, acute coronary events, and clinical implications associated with coronary artery complications in LBBAP. The mechanism of coronary injury with LBBAP involves mechanical trauma, altered coronary blood flow dynamics, and endothelial damage. Acute coronary events such as myocardial ischemia, acute coronary syndromes, and coronary artery dissection can occur during or after LBBAP, leading to significant clinical implications including the need for prompt intervention and potential impact on long-term outcomes. To avoid coronary injury and acute coronary syndrome with LBBAP, specific care strategies are recommended. These include thorough pre-procedural evaluation, expert operator technique, optimization of hemodynamics and ventricular synchrony, close monitoring for ischemic events, collaboration with cardiology specialists, and long-term follow-up. The clinical implications of coronary artery complications with LBBAP necessitate careful patient selection, informed decision-making, and a multidisciplinary approach. Future directions in this field include advancements in procedural techniques, technological innovations, risk stratification strategies, enhanced imaging modalities, research on mechanisms and prevention, and collaboration among stakeholders. By implementing these strategies and focusing on future advancements, healthcare providers can minimize the risk of coronary artery complications with LBBAP and optimize patient outcomes in cardiac resynchronization therapy.
