Percutaneous extraction of a malpositioned subclavian arterial pacing lead using the retained wire technique and a vascular closure device: a case report.

ABSTRACT:

Background

Inadvertent lead malposition (ILM) in the left ventricle (LV) via the subclavian artery is a rare complication during the insertion of cardiac implantable electronic devices (CIED). If not identified, there is a risk of systemic thromboembolism. Transarterial pacing lead extraction often requires surgical removal and carries high risks of bleeding and thromboembolism, but percutaneous extraction has also been previously described.

Case summary

A 71-year-old female presented with left homonymous hemianopia on Day 1 post-insertion of a dual-chamber permanent pacemaker (PPM). A computed tomography (CT) angiogram of the brain and aortic arch revealed an acute occlusion of a branch of the right posterior circulating artery (PCA) and a malpositioned pacing lead in the left subclavian artery. Urgent percutaneous removal of the transarterial lead using the retained wire technique was successfully performed.

Discussion

Inadvertent lead malposition in the arterial system is rare and often requires lead extraction due to systemic thromboembolic complications. The retained wire technique has been previously described for percutaneous transvenous lead extraction and exchange, but to our knowledge, we are the first to report utilizing this technique for transarterial lead extraction. Using a case report, we highlight the utility, safety, and effectiveness of the retained wire technique in extracting a malposition lead in the subclavian artery and LV.

Leadless pacing in a patient with superior vena cava syndrome undergoing lead extraction and percutaneous angioplasty.

Project description:Superior vena cava (SVC) syndrome is an uncommon but serious complication associated with chronic transvenous implanted leads. In the recent past, open-heart surgery combining lead extraction and epicardial implant was usually performed to reduce syndrome recurrences. We describe the case of a 78-year-old man successfully treated by percutaneous lead extraction associated with venous balloon angioplasty and reimplantation of leadless pacemaker. <Learning objective: Chronic vascular complications following lead implantation usually require surgical treatment, due to the need for subsequent epicardial implantation. Percutaneous lead extraction along with leadless pacing allowed effective non-surgical management of chronic complications of transvenous pacing.>.

Percutaneous Epicardial Pacing using a Novel Insulated Multi-electrode Lead.

Project description:INTRODUCTION:Epicardial cardiac resynchronization therapy (CRT) permits unrestricted electrode positioning. However, this requires surgical placement of device leads and the risk of unwanted phrenic nerve stimulation. We hypothesized that shielded electrodes can capture myocardium without extracardiac stimulation. METHODS:In 6 dog and 5 swine experiments, we used a percutaneous approach to access the epicardial surface of the heart, and deploy novel leads housing multiple electrodes with selective insulation. Bipolar pacing thresholds at prespecified sites were tested compare electrode threshold data both facing towards and away from the epicardial surface. RESULTS:In 151 paired electrode recordings (70 in 6 dogs; 81 in 5 swine), thresholds facing myocardium were lower than facing away (median [IQR] mA: dogs 0.9 [0.4-1.6] vs 4.6 [2.1 to >10], p<0.0001; swine 0.5 [0.2-1] vs 2.5 [0.5-6.8], p<0.0001). Myocardial capture was feasible without extracardiac stimulation at all tested sites, with mean ± SE threshold margin 3.6±0.7 mA at sites of high output extracardiac stimulation (p=0.004). CONCLUSION:Selective electrode insulation confers directional pacing to a multielectrode epicardial pacing lead. This device has the potential for a novel percutaneous epicardial resynchronization therapy that permits placement at an optimal pacing site, irrespective of the anatomy of the coronary veins or phrenic nerves.

Isolation of left subclavian artery with reversal of neurological and hemodynamic abnormalities after percutaneous closure.

Project description:Isolation of left subclavian artery is a rare congenital anomaly. In this abnormality, the left subclavian artery arises from the homo-lateral pulmonary artery rather than from aorta. This condition is often diagnosed by angiography and treated by surgery. The authors present a case, which had vertebro-basilar insufficiency, subclavian steal phenomenon and pulmonary plethora. All these clinical signs disappeared by a simple percutaneous intervention.

Triple lead cephalic versus subclavian vein approach in cardiac resynchronization therapy device implantation.

Project description:Cardiac resynchronization therapy (CRT) device implantation is associated with severe complications including pneumo- and hemothorax. Data on a sole cephalic vein approach (sCV), potentially preventing these complications, are limited. The aim of our study was to compare a sole cSV with a subclavian vein approach (SV) in CRT implantations with respect to feasibility and safety. We performed a prospective cohort study enrolling twenty-four consecutive de-novo CRT implantations (group A) using a sCV at two centers. Fifty-four age-matched CRT patients implanted via the SV served (group B) as reference. Procedural success rate and complications were recorded during a follow-up of 4 weeks. All CRTs could be implanted in group A, with 91.7% using cephalic access alone. In group B, CRT implantation was successfully performed in 96.3%. Procedure and fluoroscopy duration were similar for both groups (sCV vs. SV: 119?±?45 vs. 106?±?31?minutes, 17?±?9 vs 14?±?9?minutes). Radiation dosage was higher in sCV group vs. SV (2984?±?2370 vs. 1580?±?1316?cGy*cm2; p?=?0.001). There was no case of a pneumothorax in group of sCV, while two cases were observed using SV. Overall complication rate was similar (sCV: 13.0% vs. SV: 12.5%). de-novo CRT implantation using a triple cephalic vein approach is feasible. Procedure duration and complication rates were similar, while radiation dosage was higher in the sCV compared to the SV approach. Despite its feasibility in the clinical routine, controlled prospective studies with longer follow-up are required to elucidate a potential benefit with respect to lead longevity.

Simultaneous suction debulking of lead vegetation prior to percutaneous lead extraction.

Project description:The infection rates of implanted cardiac devices have increased disproportionate to the dramatic increase in implantation rates, possibly related to rising patient comorbidities. Optimum strategy in cases with larger size vegetations, however, remains to be ascertained. In the absence of an effective and less invasive alternative, such patients usually undergo open thoracotomy for lead extraction. We describe the case of a 50-year-old female presenting with recurrent methicillin-resistant Staphylococcus aureus bacteremia found to have 3 cm highly mobile vegetation on the right ventricular lead of her implanted defibrillator. While being intermediate-to-low surgical risk, she underwent AngioVac-directed suction debulking (AngioDynamics, Latham, NY, USA) of the vegetation simultaneously preceding percutaneous laser lead extraction in a single session. This less invasive alternative to open thoracotomy has been described in high surgical risk patients, but its widespread role remains unexplored. <Learning objective: Complete lead extraction is recommended in all cases of lead infection. However in the presence of large-size lead vegetation, the optimum management strategy is still controversial, especially among high-risk surgical patients. AngioVac system (AngioDynamics, Latham, NY, USA) has a centrifugal suction cannula which can offer a safer and less invasive percutaneous alternative to open thoracotomy approach, with a possibility of large-scale application due to faster recovery.>.

Percutaneous device closure of persistent ductus venosus presenting with hemoptysis.

Project description:An eight-year-old boy was evaluated for unexplained hemoptysis and cyanosis. A contrast echocardiogram was suggestive of pulmonary arteriovenous fistula. Further evaluation revealed persistent ductus venosus (PDV) and aortopulmonary collaterals. Both the PDV and aortopulmonary collaterals were closed percutaneously. PDV is amenable for device closure after detailed anatomical evaluation. Prior to closure, it is important to ensure adequate portal vein arborization into the liver and normal portal pressure after test balloon occlusion.

Computed Tomography-Guided Risk Assessment in Percutaneous Lead Extraction.

Project description:ObjectivesThe aim of this study was to assess if pre-procedural computed tomography (CT) could identify high-risk operative features and predict increased procedural complexity.BackgroundUnpredictable lead adhesions can make lead extraction complicated. Adhesions are known to affect leads with longer indwelling time but can unpredictably affect newer leads.MethodsConsecutive patients who had CTs performed ≤90 days before their planned lead extraction (LE) were included. CTs were reviewed blinded to outcome according to a preset checklist. The outcome was a combined endpoint of procedural complexity and major complications.ResultsBetween January 1, 2015 and July 1, 2018, 143 patients underwent CT and LE. Median age was 68 years (interquartile range [IQR]: 54.4 to 76.5), and 35% were female. Median age of extracted leads was 111 months, and 126 (43%) were >10 years. CT detected lead perforation ≥5 mm (n = 13), <5 mm (n = 55), severe lead adhesions (n = 65), leads touching vessel wall >1 cm (n = 102), lead fracture (n = 8), and severe ipsilateral venous stenosis/occlusion (n = 36). The procedure was complex in 63 cases. There were 2 deaths, and 6 major complications. Patients with severe lead adhesions had more complex procedures (n = 36 vs 29; p = 0.04), whereas none of the other findings on CT were significantly associated with worse outcome. In patients with leads that had an indwelling time <10 years (n = 72), severe lead adhesions on CT was associated with worse outcome in multivariable analysis (odds ratio: 6.4; 95% confidence interval: 1.4 to 30.2; p = 0.02).ConclusionsPre-procedural CT can be used to locate severe lead adhesions in patients planned for lead extraction. In patients with indwelling leads <10 years, pre-procedural CT aids in identifying patients prone to complex extractions.

Atrial tachyarrhythmias following percutaneous device closure of secundum atrial septal defects.

Project description:BackgroundAtrial tachyarrhythmias (ATs) are a major source of morbidity in the atrial septal defect (ASD) patient cohort. The optimal timing and approach of anti-arrhythmic intervention is currently unclear. Here, we sought to determine the overall rate of ATs following percutaneous ASD closure and risk factors that may predict this.MethodsA systematic search of the literature was performed using the search terms '(Secundum Atrial Septal Defects AND Atrial arrhythmias) AND (transcatheter closure or percutaneous closure or device closure)'. All studies in English reporting the rate of ATs following percutaneous closure of secundum ASDs in adult patients were included. The primary outcome was documented AT detection during follow-up ECG monitoring. A meta-regression was then performed to test for an interaction between demographic/procedural characteristics and the primary outcome.Results13 observational studies including 2366 patients were analysed. The overall post-procedure AT event detection rate was 8.6%. Multivariate meta-regression analysis revealed that only male gender was associated with a higher rate of post-procedure AT detection while utilisation of the Amplatzer Septal Occluder device was associated with a lower AT detection rate and comprised 96.2% of all devices used. A high level of heterogeneity was observed (I2-statistic 92.3%, Q value 156.8).ConclusionsOur study illustrates that despite percutaneous ASD closure, a high proportion of adult patients have ATs with male gender correlating with higher AT rates. While the Amplatzer Septal Occluder device correlated with lower AT rates, this was the overwhelmingly the predominant device used hence comparison to other devices remains challenging.
