Highlights
We report the case of a patient presenting, initially, a 3rd degree atrioventricular block after percutaneous revascularization of an ST + extended anteriorly by angioplasty and placement of an active stent on the anterior interventricular coronary artery permeable after a second post-critical coronary angiography
Complete or third degree atrioventricular block, defined by the complete and permanent interruption of the transmission of atrial impulses to the ventricles [1,2] is one of the early and relatively frequent complications of myocardial necrosis whose pathophysiology and the course differs depending on the seat of the infarction; AVB always shows anatomically extensive infarcts, the mortality of which from previous infarctions complicated by AVB remains considerable (> 60%) in the absence of early revascularization [3,4]
We report a case of complete atrioventricular block occurring initially after Percutaneous Revascularization (PR) of extensive anterior ST + (STEMI-EA)
Summary
Complete or third degree atrioventricular block (cAVB), defined by the complete and permanent interruption of the transmission of atrial impulses to the ventricles [1,2] is one of the early and relatively frequent complications of myocardial necrosis whose pathophysiology and the course differs depending on the seat of the infarction; AVB always shows anatomically extensive infarcts, the mortality of which from previous infarctions complicated by AVB remains considerable (> 60%) in the absence of early revascularization [3,4] This complication, very common before the era of revascularization, occurs in the acute phase. Note: Day 1: ST segment shift in extended anterior before thrombolysis, before percutaneous coronary revascularization
