Why the study?
Conduction restoration after revascularization is well established in ACS, but the reversibility of high degree AV block after revascularization in non-ACS settings lacks robust scientific confirmation.
Does targeted revascularization restore conduction in non-ACS patients with high degree atrioventricular block?
Does targeted revascularization restore conduction in non-ACS patients with high degree atrioventricular block?
This case suggests that targeted revascularization may restore conduction in non-ACS patients with high degree AV block, potentially avoiding the need for permanent pacemaker implantation.
Possible conduction recovery after revascularization in non-ACS high-degree AV block is hypothesis-generating; leaves open whether it alters pacemaker decisions pending prospective data.
Conduction restoration in second- and third-degree atrioventricular (AV) block after revascularization in acute coronary syndrome (ACS) setting is well established, however this is not the case in non-ACS setting. We present a case of a patient referred for permanent pacemaker implantation, due to high degree AV block (HAVB), who restored his conduction possibly due to targeted revascularization. Thus, this case sheds insight in the reversibility potential of HAVB after revascularization in non-ACS patients, which although signified in current literature, is still far from being a recommendation, due to lack of robust scientific confirmation.
