“…In cases of lead malposition in the left ventricle, the right bundle branch block pattern occurs in ECG. 1 - 3 Nevertheless, in our case, ECG did not demonstrate the pattern ( Figure 1 ) despite the presence of the lead in the left ventricle, which may have been due to the placement of the lead next to the interventricular septum ( Figure 4B ).…”

“…One early-symptomatic case of ischemic stroke with left homonymous hemianopia one day post-insertion of a dual-chamber permanent pacemaker was presented by Primero et al [8]. Other significant complications of ILMLV included perforation of the mitral valve or of the LV wall, mitral valve regurgitation due to the malpositioned lead bending the valve leaflets, risk of aortic and mitral valve infectious endocarditis [9], and higher probability of diaphragmatic pacing and loss of capture [4]. Fortunately, none of these complications occurred in our patient whose malpositioned lead was diagnosed by chance during a routine TTE.…”

Inadvertent Lead Malposition in Left Ventricle is a rare and underdiagnosed incident, which may occur during implantation of cardiac electronic devices and may remain asymptomatic. We reported the case of a 71-year-old man who was implanted with a ventricular single-chamber pacemaker for a slow atrial fibrillation with syncope and whose routine transthoracic echocardiography 23 months after implantation displayed a malposition of the pacemaker lead into the Left Ventricle through a patent foramen oval. The patient was asymptomatic. The electrocardiogram showed right bundle branch block QRS-paced morphology with a positive QRS pattern in V1, a median paced QRS axis on the frontal plane at −120˚, a Precordial transition on V5. At the lateral Chest X-ray the lead curved backwards to the spine. Given the age of this old patient who already received oral anticoagulant for Atrial Fibrillation and the Lead malposition discovered 23 months after pacemaker's implantation, we decided to maintain the lead in LV and continue anticoagulation.

“…To confirm venous access, the guidewire should be advanced to the inferior vena cava or the pulmonary artery. When the lead is inserted through the venous system but comes across an atrial septal defect, a left anterior oblique (LAO) view is a good option showing the lead go beyond the spine towards the LV contour 7 .

Introduction: Inadvertent implantation from the subclavian/axillary arteries is uncommon and has been rarely reported. Complications are frequent, mainly driven by thromboembolic events. Lead extraction, depending on the dwell time may be challenging and associated with thromboembolic events Case Report: We report the case of an 87‐year‐old man who had involuntarily pacemaker lead implanted into the left ventricle through the left subclavian artery. An extraction procedure was performed with surgical dissection to the artery and simple traction of the probe without complication. Conclusion: Percutaneous lead extraction using surgical dissection is a therapeutic option for less than one year old left ventricle inadvertent lead implantation.
