Delayed presentation of right ventricular lead perforation following defibrillator implantation: a case report.

Project description:BackgroundPerforation of a device lead through the myocardium is a recognized complication of cardiac device implantation. The associated morbidity and mortality are significant, even though it is a relatively rare complication. Therefore, it is vital for acute clinicians to be aware of the diagnosis and subsequent management of myocardial perforation.Case summaryWe present the case of a 48-year-old woman who presented to the emergency department 1 month following implantable cardioverter-defibrillator implantation with chest and shoulder pain. Initial assessment revealed bilateral pleural effusions and anaemia. Computerized tomography of her chest and abdomen demonstrated a pericardial effusion, but it was transthoracic echocardiography that confirmed the diagnosis of right ventricular perforation. Urgent system revision was undertaken.DiscussionThis case highlights the importance of clinical suspicion and the use of diagnostic echocardiography as an important diagnostic tool in symptomatic patient's post-cardiac device implantation.

Case report: Left ventricular perforation caused by right ventricular pacemaker lead

Project description:Background Perforation of the interventricular septum and left ventricular (LV) free wall by a right ventricular (RV) lead is an extremely rare and potentially life-threatening complication. In this case report, we discussed the diagnosis and management of a very unusual complication of pacemaker (PM) implantation, i.e., LV perforation brought on by an RV pacing lead. Case summary A 92-year-old man was admitted to Xiangyang No.1 People’s Hospital due to a complete atrioventricular block. We performed a dual-chamber PM implantation; however, on the second postoperative day (POD), pacemaker failure occurred. Thoracic computed tomography (CT) scan showed that RV lead had pierced the interventricular septum and LV free wall. A transvenous lead extraction of the penetrating lead was performed uneventfully, and RV lead was refixed at the lower RV septum on the 5th POD. Discussion Identification of high-risk patients is mandatory to prevent this serious complication, and transvenous lead extraction with cardiac surgery backup may be an option.

Left ventricular free wall perforation by a right ventricular pacemaker lead: a case report.

Project description:BackgroundLead perforation is one of the major complications of pacemaker implantation, but cases of right ventricular (RV) lead perforation through the septum and left ventricle are rarely reported. We described a rare case of left ventricular (LV) free wall perforation by an RV lead and the management of this complication.Case summaryAn 84-year-old man was admitted with a dual-chamber pacemaker due to pacing failure caused by an RV lead fracture. New lead implantation was performed on the next day, but pacing failure occurred again on the second post-operative day (POD). We found the lead perforation on the fluoroscopy during temporary pacemaker insertion. Computed tomography scan and transthoracic echocardiogram showed that the added lead perforated through both the septum and LV free wall. A new lead was inserted on the fourth POD, and an off-pump open chest surgery for extraction of the penetrating lead was performed uneventfully on the 20th POD.DiscussionWe considered that some features of the lead (SelectSecure 3830-69, Medtronic) may be related to this complication, as the lead was very thin, had a non-retractable bare screw and was inserted with a dedicated delivery catheter. We have to be careful when performing implantation of this kind of lead to avoid such a rare complication.

Repair of pacemaker lead-induced right ventricular perforation via a left mini-thoracotomy.

Project description:Cardiac perforation is a rare but serious and life-threatening complication of permanent pacemaker implantation, with an incidence of 0.1-6%. Surgery is usually performed through a median sternotomy; however, sternotomy-related morbidity remains a concern. Herein, we report a case of surgical repair performed via a left mini-thoracotomy for a right ventricular perforation caused by implantation of a permanent pacemaker lead in a 56-year-old woman. Through the left fifth intercostal space, the pacemaker lead was observed to have penetrated the left ventricular myocardium, reaching the pericardium. The lead had passed through the right ventricle and the inferior ventricular septum and protruded from the left ventricular myocardium. After pacemaker lead removal, a dark blow-out type hemorrhage occurred; hence, repair was performed using a pair of pledgeted Mattress sutures. In conclusion, left mini-thoracotomy provides an adequate surgical field and has less impact on hemodynamics when operating at the cardiac apex. <Learning objective: Left mini-thoracotomy facilitates easy access to the ventricular apex during in situ management, and also provides an adequate surgical field and has insignificant impact on hemodynamics when operating at the cardiac apex. We also present a detailed surgical movie that reveals a penetrating pacemaker lead, hemorrhage after removing the pacemaker lead, and making a stitch through left mini-thoracotomy.>.

Additional left ventricular septal lead facilitates R-wave sensing of implantable cardioverter-defibrillator in arrhythmogenic right ventricular cardiomyopathy: a case report.

Project description:BackgroundImplantable cardioverter-defibrillator (ICD) implantation is a key therapeutic option in arrhythmogenic right ventricular cardiomyopathy (ARVC) to prevent sudden cardiac death due to ventricular tachycardia (VT) and fibrillation (VF). However, sub-optimized R-wave sensing due to myocardium loss interferes with VT/VF identification and appropriate therapy. We tried to implant a 3830 lead to the left ventricular septum (LVS) to facilitate ICD sensing in an ARVC patient.Case summaryA 68-year-old woman diagnosed with ARVC was scheduled to undergo ICD implantation. Initially, no sites with suitable R-wave amplitudes were found in the right ventricle (RV) to deploy the defibrillation lead (<3.0 mV). It was likely due to severe RV involvement, but the LVS myocardium was more preserved based on cardiac magnetic resonance imaging. Therefore, we implanted a 3830 lead into the deep area of the septum to facilitate R-wave sensing. During the procedure from the right to left septum, the R-wave amplitude significantly increased (2.6 to 4.3-7.1 mV). Left ventricular septum pacing was finally achieved with favourable R-wave sensing (9.9 mV 24 h post-operation). The 3830 lead was plugged into the IS-1 port, while the defibrillation lead was plugged into the DF-1 port. After a 4-month follow-up, the R-wave amplitude of the 3830 lead was 11.1 mV.DiscussionWhen the R-wave sensing is not acceptable for ICD implantation in ARVC patients, it is critical to assess myocardial conditions comprehensively. If the septal myocardium is preserved, implanting a 3830 lead to the deep or LVS is feasible to improve R-wave sensing.
