Rescue Percutaneous Coronary Intervention for a Lethal "Jailed" Septal Perforator Branch to Resolve Delayed Complete Atrioventricular Block

Abstract

Delayed complete atrioventricular (AV) block associated with an occluded septal perforator branch (SPB) is an uncommon complication after performing percutaneous coronary intervention (PCI) for the left anterior descending coronary artery (LAD). Here we report the case of a 74-year-old man who underwent elective PCI for proximal LAD complicated with occlusion of the first major SPB and developed a complete AV block 78 hours after PCI was performed. The patient received a temporary transvenous pacemaker via the jugular vein and successfully underwent balloon angioplasty of the lethal "jailed" SPB, resulting in recovery from the complete AV block. Permanent pacemaker implantation was avoided. Our findings indicate the importance of postprocedural monitoring and consideration of rescue PCI for an occluded SPB in cases of complicated AV conduction disturbances.(Int Heart J 2019; 60: 457-461)

An Acute Anterior Reinfarction Complicating with Transient Symptomatic Total Atrioventricular Block

“…Two thirds of patients (66 %) with TAVB complicating an anterior MI died during hospitalization compared to only 37% of patients with an inferior/ posterior MI and TAVB. 2,3 Total AV block complicating the anterior MI has high mortality and poorer outcome, generally propagated by extensive infarction involving the conduction system distal to the AV node, 4,5 lead to extensive acute left ventricular damage and hemodynamic instability. 7,8,9 Case illustration A 44 years old man, in the previous referrer hospital, patient had history of anterior extensive STEMI at 2 days before admission and underwent primary percutaneous coronary intervention (PPCI) with stent implantation DES at proximal LAD.…”
