Permanent pacemaker implanted into patient’s left ventricle via subclavian artery by mistake: a case report

Abstract

BackgroundAlthough various iatrogenic complications could be observed in the process of permanent pacemaker implantation, pacemaker electrode mistakenly implanted into left ventricle via subclavian artery and aortic valve has not been reported.Case presentationHerein, we reported a 71-year-old woman with permanent pacemaker mistakenly implanted into the left ventricle. During the operation of permanent pacemaker implantation, puncture was performed on her subclavian artery by mistake, and then the pacemaker electrode was put into the cardiac apex of left ventricle via ascending aorta reversely.ConclusionThe further operation could be conducted.

Avoidance and early diagnosis of erroneous permanent pacemaker placement into the left ventricle: A case report

“…Right ventricular pacing causes LBBB morphology, whereas left ventricular pacing should be suspected if ECG shows RBBB morphology with tall R-waves in lead in V1. 5,6 (6) If ventricular pacing is absent at baseline as in patients with sick sinus syndrome or intermittent heart block then performing ECG during threshold testing to identify the QRS morphology should be considered. (7) Post-pacemaker chest X-ray should be obtained in anteroposterior and lateral views whenever possible.…”

“…(5) Post‐pacemaker ECG interpretation is very important particularly if ventricular pacing is present. Right ventricular pacing causes LBBB morphology, whereas left ventricular pacing should be suspected if ECG shows RBBB morphology with tall R‐waves in lead in V1 5,6 . (6) If ventricular pacing is absent at baseline as in patients with sick sinus syndrome or intermittent heart block then performing ECG during threshold testing to identify the QRS morphology should be considered.…”

Avoidance and Early Diagnosis of Erroneous Permanent Pacemaker Placement into the Left Ventricle: A Case Report

“…After the pacemaker is implanted, correct positioning of the pacemaker may also be seen through ECG. Right ventricular pacing is indicated when ECG shows left bundle branch block appearance, while left ventricular pacing is seen in right bundle branch block patterns (5).…”

“…1,3 Inadvertent lead placement into the left ventricle (LV) is a rare but recognized complication of CEID use. 2,[4][5][6][7][8][9][10][11][12][13][14][15] This paper presents a case report of a patient who underwent atrioventricular node (AVN) ablation with subsequent misplacement of her single lead pacemaker.…”
