Late perforation of a passively fixated pacemaker lead through the right ventricle. A report and review of literature.

Project description:Lead perforation is one of the serious complications associated with cardiac pacemakers and implantable cardiac defibrillators. Late perforations - occurring more than one month after placement - are exceedingly rare and are usually more associated with actively fixed leads rather than passively fixed tined leads. We present a case of blunt ended tined lead perforation after 4 months of implantation managed by a two-step hybrid minimally invasive approach consisting of mini-thoracotomy and lead tip transection, followed by trans-venous lead extraction. <Learning objective: Late perforation of a pacemaker lead (occurring more than one month after placement) is an exceedingly rare complication and is usually more associated with actively fixed leads rather than passively fixed tined leads.

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.

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.>.

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.

Unguarded left atrioventricular orifice: An unusual cause of hypoplastic left ventricle and double-outlet right ventricle with intact ventricular septum.

Project description:An unguarded atrioventricular orifice is an extremely rare congenital anomaly characterized by the absence of the atrioventricular valve in varying proportions. While atresia of the mitral or aortic valves are usually described as causes for hypoplastic left heart, our case highlights the role of free atrioventricular valve regurgitation and consequent volume loss of the left heart, giving rise to a small left ventricle. There was an associated double-outlet right ventricle and Type B aortic interruption. While we have attempted to discuss the complex management options in this scenario, the parents decided to withdraw further care.
