Project description:BackgroundFluoroscopic guidance is the traditional method for the implantation of transvenous temporary cardiac pacemakers (TVTPs). This study aimed to compare the time, effectiveness, and safety of real-time three-dimensional transesophageal echocardiography (3D TEE) with those of fluoroscopy in guiding TVTP implantation.MethodsThe records of patients who underwent transcatheter aortic valve implantation (TAVI) guided by real-time 3D TEE or fluoroscopy between July 1, 2016, and June 30, 2020, were retrospectively analyzed. TVTPs were implanted by anesthesiologists via the right internal jugular vein (IJV) in the real-time 3D TEE-guided group (3D TEE group), and by interventional cardiologists via the femoral vein in the fluoroscopy-guided group (fluoro group).ResultsA total of 143 patients (3D TEE-group n=79, and fluoro group n=64) were included. No statistical differences were observed in the baseline characteristics of the two groups. TVTPs were successfully implanted in all of the patients. The needle-to-pace time was significantly shorter in 3D TEE group than in fluoro group (5.2±2.9 vs. 8.5±4.6 min, P<0.001). Further, the incidence of access complications was significantly lower in 3D TEE group than in fluoro group (3.8% vs. 12.5%, P<0.05). One patient in fluoro group who suffered cardiac perforation underwent drainage via pericardiocentesis. No patients in either group died because of TVTP placement. The total complication rates were significantly lower in 3D TEE group than in fluoro group (19.0% vs. 39.1%, P<0.05). No statistically significant differences existed between groups in terms of pacing threshold, the incidence of permanent pacemaker insertion after surgery, the length of postoperative intensive care unit (ICU) stay, or the duration of postoperative hospitalization.ConclusionsReal-time 3D TEE-guided can be used to effectively, quickly, and safely guide TVTP implantation. The procedure can be performed by properly trained anesthesiologists. Therefore, real-time 3D TEE is a suitable option for guiding perioperative TVTP implantation in patients undergoing cardiac surgery.

Project description:AimsSince their introduction in 1958, traditional cardiac pacemakers have undergone considerable upgrades over the years, but they continue to have a complication rate of ∼3.8%-12.4%. There are no randomized controlled trials comparing outcomes of leadless pacemakers (LPM) with single-chamber transvenous pacemakers (TV-VVI). The aim is to assess the differences in the procedural complications and in-hospital outcomes between LPM and TV-VVI implants.Methods and resultsWe queried the national inpatient database from 2016 to 2019 to include adult patients undergoing LPM and TV-VVI. Admissions for leadless and single-lead transvenous pacemakers were identified by their appropriate ICD-10 codes. Complications were identified using ICD-10 codes that mostly represent initial encounter. The difference in outcomes was assessed using multivariable logistic regression and 1:1 propensity score matching between the two cohorts. Thirty-five thousand four hundred thirty expanded samples of admissions were retrieved of which 27 650 (78%) underwent TV-VVI with a mean age 81.3 ± 9.4 years and 7780 (22%) underwent LPM with a mean age of 77.1 ± 12.1 years. The LPM group had a higher likelihood of in-hospital mortality [adjusted odds ratio (aOR): 1.63, 95% CI (1.29-2.05), P < 0.001], vascular complications [aOR: 7.54, 95% CI (3.21-17.68), P < 0.001], venous thromboembolism [aOR: 3.67, 95% CI (2.68-5.02), P < 0.001], cardiac complications [aOR: 1.79, 95% CI (1.59-2.03), P < 0.001], device thrombus formation [aOR: 5.03, 95% CI (2.55-9.92), P < 0.001], and need for a blood transfusion [aOR: 1.54, 95% CI (1.14-2.07), P < 0.005]. The TV-VVI group had higher likelihood of in-hospital pulmonary complications [aOR:0.68, 95% CI (0.54-0.87), P < 0.002] and had a need for device revisions [aOR:0.42, 95% CI (0.23-0.76), P < 0.004].ConclusionThere is a higher likelihood of all-cause in-hospital mortality and complications following LPM implantation in comparison to TV-VVI. This could be related to higher co-morbidities in the LPM group. Clinical trials aimed to accurately compare these two groups should be undertaken.
