Project description:BackgroundSubclavian venous spasm is an uncommon complication during permanent pacemaker implantation. The exact aetiology of subclavian venous spasm is not clear but has been suggested to be due to either mechanical irritation of the vein during needle puncture or due to chemical irritation from contrast injection. Here, we report a case of an unyielding subclavian vein valve that impeded guidewire advancement and the repeated guidewire manipulation led to venous spasm.Case summaryA 45-year-old woman with a history of surgical repair of Tetrology of Fallot in childhood presented with symptomatic bifascicular block and underwent a permanent pacemaker implantation. A subclavian venogram done prior to the procedure showed a prominent valve in the distal portion of the vein. Following venous puncture, guidewire advancement was impeded by the prominent valve. The resulting guidewire manipulation led to subclavian venous spasm necessitating a medial subclavian venous puncture and access.DiscussionProlonged mechanical irritation of the vein during pacemaker implantation may lead to venous spasm impeding pacemaker implantation. Early identification of an impeding valve and obtaining access medial to the valve may help prevent this uncommon complication.

Project description:We report a case of pulmonary embolism while performing pacemaker implantation in an obese patient and its management as well as certain precautions that one must consider in an obese patient especially under conscious sedation. Air embolism during pacemaker implantation although rare can be life-threatening in certain conditions such as massive pulmonary embolism. Air embolism during this procedure mainly occurs through open sheath just before inserting the lead. Certain risk factors associated with this condition include deep inspiration, frequent coughing, advanced age, sheath with larger diameter, and sedatives. Obesity along with associated factors including sleep apnea, restrictive lung disease, and challenges during airway management can create troubles during pacemaker implantation. Conscious sedation is usually required when a patient becomes restless during the procedure either due to pain or prolonged supine position. At times a patient can transiently go into the deep sedation and a deep inspiration during this phase can be detrimental in a procedure where it is undesirable and adds to the risk of air embolism. Here we discuss the management and alternative methods which can be used to avoid such complications. <Learning objective: Pacemaker implantation procedure can be performed with minimal sedation instead of conscious sedation. Although conscious sedation seems more suitable, it carries the risk of complications such as air embolism that can be precipitated by involuntary deep inspiration during the procedure. When conscious sedation is required one must reconsider the need as well as alternatives so as to avoid such complications.>.

Project description:Iatrogenic arteriovenous fistula is a unique complication during pacemaker implantation. A 55-year-old man was posted for pacemaker implantation for recurrent unexplained syncope with trifascicular AV block. After axillary/subclavian venous puncture and introduction of RV lead, arterial spurting was immediately noticed as the the sheath was peeled away. After dissecting the overlying pectoralis muscle, deep sutures and manual compression achieved hemostasis. However, Subclavian arteriogram revealed an arteriovenous fistula from a lateral thoracic artery branch to the innominate vein. Hilal coils were deployed near the fistulous orifice, leading to complete resolution of the leak. After 3 days, pacemaker was implanted from right side. A multidisciplinary approach was the key to successful outcome.

Project description:OBJECTIVE:Permanent pacemaker implantation (PPMI) after transcatheter aortic valve implantation (TAVI) is the most common complication after the procedure. PPMI rates remain high with the new-generation TAVI devices despite improved outcomes concerning paravalvular aortic regurgitation and vascular access complications. However, the impact of PPMI on mortality and clinical outcome is still a matter of debate, and data with new-generation devices on this matter are scarce. Therefore, we sought to analyse the influence of PPMI in patients treated with the new-generation devices on one-year outcome. METHODS:We enrolled 612 consecutive patients without prior pacemaker undergoing transfemoral TAVI with the new-generation devices. Patients with or without PPMI were compared with respect to clinical outcome within one year. RESULTS:PPMI was performed in 168 patients (24.4% of the overall study population). There was no significant difference in one-year outcome concerning all-cause mortality (PPMI vs. no-PPMI: 12.2% vs. 12.5%, p?=?0.94), rate of major adverse events including cardiac, cerebral or valve-related events and bleeding complications (22.1% vs. 24.5%, p?=?0.55) or need for rehospitalisation due to cardiac symptoms (16.1% vs. 18.1%, p?=?0.63). In patients with reduced ejection fraction (<45%) there was also no impact of PPMI on one-year mortality (14.3% vs. 15.7%, p?=?0.86). Furthermore, multivariate analysis did not reveal PPMI to be independently associated with one-year mortality (odds ratio 0.94, 95% confidence interval 0.50-1.74, p?=?0.83). CONCLUSIONS:In this large all-comers TAVI population with new-generation devices the need for postprocedural PPMI did not show a statistical significant impact on survival or combined endpoint of major adverse events within one year.

Project description:The number of patients undergoing transcatheter aortic valve replacement (TAVR) worldwide is increasing steadily. Atrioventricular conduction disturbances, with or without the need for permanent pacemaker (PPM) implantation, are one of the most common adverse events after TAVR. Among transcatheter heart valves (THV), rates of conduction abnormalities vary from less than 10 % to more than 50 %. Depending on the reported data referred to, historical data showed that up to one-third of the patients required implantation of a PPM following TAVR. Although generally considered as a minor complication, PPM may have a profound impact on prognosis and quality of life after TAVR. Current data support the hypothesis that conduction abnormalities leading to pacemaker dependency result from mechanical compression of the conduction system by the prosthesis stent frame and individual predisposing conduction defects such as right bundle-branch block (RBBB). With several large randomised trials and registry studies having been published recently and second generation THV having been introduced, the debate about predictors for pacemaker implantation and their impact on outcome after TAVR is still ongoing.

Project description:BackgroundThe incidence of permanent pacemaker (PPM) implantation is higher following mitral valve surgery (MVS) with ablation for atrial fibrillation (AF) compared with MVS alone.ObjectivesThis study identified risk factors and outcomes associated with PPM implantation in a randomized trial that evaluated ablation for AF in patients who underwent MVS.MethodsA total of 243 patients with AF and without previous PPM placement were randomly assigned to MVS alone (n = 117) or MVS + ablation (n = 126). Patients in the ablation group were further randomized to pulmonary vein isolation (PVI) (n = 62) or the biatrial maze procedure (n = 64). Using competing risk models, this study examined the association among PPM and baseline and operative risk factors, and the effect of PPM on time to discharge, readmissions, and 1-year mortality.ResultsThirty-five patients received a PPM within the first year (14.4%), 29 (83%) underwent implantation during the index hospitalization. The frequency of PPM implantation was 7.7% in patients randomized to MVS alone, 16.1% in MVS + PVI, and 25% in MVS + biatrial maze. The indications for PPM were similar among patients who underwent MVS with and without ablation. Ablation, multivalve surgery, and New York Heart Association functional (NYHA) functional class III/IV were independent risk factors for PPM implantation. Length of stay post-surgery was longer in patients who received PPMs, but it was not significant when adjusted for randomization assignment (MVS vs. ablation) and age (hazard ratio [HR]: 0.81; 95% confidence interval [CI]: 0.61 to 1.08; p = 0.14). PPM implantation did not increase 30-day readmission rate (HR: 1.43; 95% CI: 0.50 to 4.05; p = 0.50). The need for PPM was associated with a higher risk of 1-year mortality (HR: 3.21; 95% CI: 1.01 to 10.17; p = 0.05) after adjustment for randomization assignment, age, and NYHA functional class.ConclusionsAF ablation, multivalve surgery, and NYHA functional class III/IV were associated with an increased risk for permanent pacing. PPM implantation following MVS was associated with a significant increase in 1-year mortality.

Project description:Data regarding the impact of infra-Hisian conduction disturbances leading to permanent pacemaker implantation (PPI) after transcatheter aortic valve implantation (TAVI) remain limited. The aim of this study was to determine the impact of right and/or left bundle branch block (RBBB/LBBB) on post-TAVI PPI. We performed a systematic literature review to identify studies reporting on RBBB and/or LBBB status and post-TAVI PPI. Study design, patient characteristics, and the presence of branch block were analyzed. Odds ratios (ORs) with 95% CI were extracted. The final analysis included 36 studies, reporting about 55,851 patients. Data on LBBB were extracted from 33 studies. Among 51,026 patients included, 5503 showed pre-implant LBBB (11.9% (10.4%-13.8%)). The influence of LBBB on post-TAVI PPI was not significant OR 1.1474 (0.9025; 1.4588), p = 0.2618. Data on RBBB were extracted from 28 studies. Among 46,663 patients included, 31,603 showed pre-implant RBBB (9.2% (7.3%-11.6%)). The influence of RBBB on post-TAVI PPI was significant OR 4.8581 (4.1571; 5.6775), p < 0.0001. From this meta-analysis, the presence of RBBB increased the risk for post-TAVI PPI, independent of age or LVEF, while this finding was not confirmed for patients experimenting with LBBB. This result emphasizes the need for pre-operative evaluation strategies in patient selection for TAVI.
