RESUMEN
BACKGROUND: The real-world data on the safety profile of transvenous lead extraction (TLE) for infected cardiac implantable electronic devices (CIED) among elderly patients is not well-established. This study aimed to evaluate the hospital outcomes between patients of different age groups who underwent TLE for infected CIED. METHOD: Using the Nationwide Readmissions Database, our study included patients aged ≥18 years who underwent TLE for infected CIED between 2017 and 2020. We divided the patients into four groups: Group A. Young (<50 years), Group B. Young intermediate (50-69 years old), Group C. Older intermediate (70-79 years old), and Group D. Octogenarian (≥80 years old). We then analyzed the in-hospital outcome and 30-day readmission between these age groups. RESULTS: A total of 10,928 patients who were admitted for TLE of infected CIED were included in this study: 982 (9.0%) patients in group A, 4,234 (38.7%) patients in group B, 3,204 (29.3%) patients in group C and 2,508 (23.0%) of patients in group D. Our study demonstrated that the risk of early mortality increased with older age (Group B vs. Group A: OR: 1.92, 95% CI: 1.19-3.09, p < .01; Group C vs. Group A: OR: 2.47, 95% CI: 1.51-4.04, p < .01; Group D vs. Group A: OR: 2.82, 95% CI: 1.69-4.72, p < .01). The risk of non-home discharge also increased in elderly groups (Group B vs. Group A: OR: 1.89; 95% CI: 1.52-2.36; p < .01; Group C vs. Group A: OR: 2.82; 95% CI 2.24-3.56; p < .01; Group D vs. Group A: OR: 4.16; 95% CI: 3.28-5.28; p < .01). There was no significant difference in hospitalization length and 30-day readmission between different age groups. Apart from a higher rate of open heart surgery in group A, the procedural complications were comparable between these age groups. CONCLUSION: Elderly patients had worse in-hospital outcomes in early mortality and non-home discharge following the TLE for infected CIED. There was no significant difference between elderly and non-elderly groups in prolonged hospital stay and 30-day readmission. Elderly patients did not have a higher risk of procedural complications.

BACKGROUND: Cardiac implantable electronic device (CIED) implantation is increasingly performed worldwide with improving safety. Outpatient CIED implantation has similar complication rates compared to those implants which are hospitalized. Here, we analyze patient preferences on discharge timing after CIED implantation. OBJECTIVE: To identify and understand the factors contributing to patient preferences towards same-day or next-day discharge after CIED implantation. METHODS: One hundred and two patients undergoing new CIED implants were included in the study at two separate hospitals in CT (CT group) and FL (FL group) from 2018-2019. A 7-question survey was administered to the patients after the procedure. Survey responses and demographic data were statistically analyzed. RESULTS: Seventy-four percent of CT group and 58% of the FL group responded with a 10 score (0-10) that they were ready to be discharged home the same day (p=0.09). Both groups reported a low number of patients feeling safer by having a remote monitor provided at the time of discharge (44% CT group, 28% FL group; p=0.123). The mean distance of patients living from the hospital in CT group (21.6 miles) was significantly lower than that for the FL group (35.5 miles); p=0.01. Hypertension (86% vs 52%; p=0.0002) and Diabetes mellitus (44% vs 21%; p=0.013) were more prevalent in the FL group compared to the CT group. CONCLUSION: Despite the influence of local practices, the majority of patients preferred same-day discharge after CIED implantation. Improved patient education regarding the ability of remote monitors to provide real-time response to acute events is needed.
RESUMEN
BACKGROUND: Utilization of catheter ablation of ventricular tachycardia (VT) has steadily increased in recent years. Exploring short-term outcomes is vital in health care planning and resource allocation. METHODS: The Nationwide Readmissions Database from 2010 to 2014 was queried using the ICD-9 codes for VT (427.1) and catheter ablation (37.34) to identify study population. Incidence, causes of 30-day readmission, in-hospital complications as well as predictors of 30-day readmissions, complications, and cost of care were analyzed. RESULTS: Among 11 725 patients who survived to discharge after index admission for VT ablation, 1911 (16.3%) were readmitted within 30 days. Paroxysmal VT was the most common cause of 30-day readmission (39.51%). Dyslipidemia, chronic kidney disease (CKD), previous CABG, congestive heart failure (CHF), chronic pulmonary disease, and anemia predicted increased risk of 30-day readmissions. The overall in-hospital complication rate was 8.2% with vascular and cardiac complications being the most common. Co-existing CKD and CHF and the need for mechanical circulatory support (MCS) predicted higher complication rates. Similarly increasing age, CKD, CHF, anemia, in-hospital use of MCS or left heart catheterization, teaching hospital, and disposition to nursing facilities predicted higher cost. CONCLUSION: Approximately one in six patients was readmitted after VT ablation, with paroxysmal VT being the most common cause of the readmission. A complication rate of 8.2% was noted. We also identified a predictive model for increased risk of readmission, complication, and factors influencing the cost of care that can be utilized to improve the outcomes related to VT ablation.

BACKGROUND: Implantable cardioverter defibrillator (ICD) implantation is being performed differently at many hospitals, with some keeping patients overnight after procedure while others discharge patients home same day. In addition, many centers are now performing ICD surgery while on warfarin anticoagulation. There are, however, limited data on outpatient ICD surgery on anticoagulated (AC) patients. OBJECTIVE: We wished to evaluate the safety of performing outpatient ICD surgery with and without warfarin anticoagulation. METHODS: We evaluated 866 patients who underwent outpatient ICD surgery between April 2010 and September 2014. Patients who were on novel oral anticoagulants, or did not have an international normalized ratio drawn within 24 hours of the procedure were excluded and the remainder were divided into two groups based on whether they were on (n = 230) or off (n = 518) warfarin anticoagulation. We evaluated both procedural and 30-day complications in both groups. RESULTS: The complication rate at 30 days in the warfarin AC group was 4.3%, while in the nonanticoagulated (NAC) group was 2.9% and not significantly different (P = 0.31). However, the pocket hematoma rate in the warfarin anticoagulated group was 3.5%, as compared to the NAC group that was 0.4% (P = 0.001). CONCLUSION: Complications from ICD surgery are low in the ambulatory setting on or off warfarin anticoagulation and appear to be comparable. However, warfarin use during ICD surgery is associated with an increased risk of pocket hematoma.

Knowledge of the impact of paroxysmal and persistent atrial fibrillation (AF) after catheter ablation on in-hospital outcomes and 30-day readmission remains limited. This study aimed to evaluate the procedural outcomes and 30-day readmission rates among patients with paroxysmal or persistent AF who were hospitalized for AF ablation. Using the Nationwide Readmissions Database, our study included patients aged ≥18 years with AF who were hospitalized and underwent catheter ablation during 2017-2020. Then, we compared the in-hospital procedural outcomes and 30-day readmission rates between patients with paroxysmal and persistent AF, respectively. Our study included 7310 index admissions for paroxysmal AF ablation and 9179 index admissions for persistent AF ablation. According to our analysis, there was no significant difference in procedural complications-namely, cerebrovascular accident, vascular complications, major bleeding requiring blood transfusion, phrenic nerve palsy, pericardial complications, and systemic embolization-between the persistent and paroxysmal AF groups. There was also no significant difference in early mortality between these groups (0.5% vs. 0.7%; P = .22). Persistent AF patients had significantly higher rates of prolonged index hospitalization (9.9% vs. 7.2%; P < .01) and non-home discharge (4.8% vs. 3.1%; P < .01). The 30-day readmission rates were comparable in both groups (10.0% vs. 9.5%; P = .34), with recurrent AF and heart failure being two of the most common causes of cardiac-related readmissions. Catheter ablation among hospitalized patients with paroxysmal or persistent AF resulted in no significant difference in procedural complications, early mortality, or 30-day readmission. This suggests that catheter ablation of AF can be performed with a relatively similar safety profile for both paroxysmal and persistent AF.
RESUMEN
Background: The real-world data on the safety profile of ventricular tachycardia (VT) ablation among elderly patients is not well-established. This study aimed to evaluate the procedural outcomes among those aged 18-64 years versus those aged ≥65 years who underwent catheter ablation of VT. Method: Using the Nationwide Readmissions Database, our study included patients aged ≥18 years who underwent VT catheter ablation between 2017 and 2020. We divided the patients into non-elderly (18-64 years old) and elderly age groups (≥65 years old). We then analyzed the in-hospital procedural outcome and 30-day readmission between these two groups. Results: Our study included 2075 (49.1%) non-elderly patients and 2153 (50.9%) elderly patients who underwent VT ablation. Post-procedurally, elderly patients had significantly higher rates of prolonged index hospitalization (≥7 days; 35.5% vs. 29.3%, p < .01), non-home discharge (13.4% vs. 6.0%, p < .01), 30-day readmission (17.0% vs. 11.4%, p < .01), and early mortality (5.5% vs. 2.4%, p < .01). There was no significant difference in the procedural complications between two groups, namely vascular complications, hemopericardium/cardiac tamponade, cerebrovascular accident (CVA), major bleeding requiring blood transfusion, and systemic embolization. Through multivariable analysis, the elderly group was associated with higher odds of early mortality (OR: 7.50; CI 1.86-30.31, p = .01), non-home discharge (OR: 2.41; CI: 1.93-3.00, p < .01) and 30-day readmission (OR: 1.58; CI 1.32-1.89, p < .01). Conclusion: Elderly patients have worse in-hospital outcome, early mortality, non-home discharge, and 30-day readmission following catheter ablation for VT. There was no significant difference between elderly and non-elderly groups in the procedural complications.
RESUMEN
BACKGROUND: Progress in implantable cardiac defibrillator (ICD) technology has allowed for switching the sensing polarity for the detection of ventricular fibrillation (VF). However, whether one sensing polarity confers additional advantage over the other is not known. OBJECTIVES: To determine whether one sensing polarity is superior to the other for the detection of VF. METHODS: Patients were enrolled into a prospective randomized study of sensing of VF and R waves in normal rhythm. Sensing of VF was determined by number of under sensed beats (USB), and time to detection of VF (TDVF). Each patient underwent ICD implantation followed by testing of the ICD. At each induction, patients were randomized to sensing in extended bipolar (EBP) or true bipolar (TBP) configuration. Additionally, R waves were compared at implant and at 1-month follow-up. RESULTS: A total of 50 patients were enrolled into the study. When evaluating the primary endpoint, no difference was found between USB in EBP or TBP configuration; 1.1 ± 1.2 beats versus 1.3 ± 1.3 beats; P = NS. Also, no difference was found between TDVF in EBP or TBP configurations; 5.9 ± 0.6 seconds versus 5.9 ± 0.6 seconds; P = NS. With regard to the secondary endpoints, there was no difference between R waves in EBP or TBP configurations at the time of implant 10.9 ± 4.8 mV versus 10.9 ± 4.8 mV P = NS; or at 1-month follow-up 12.4 ± 4.7 mV versus 12.0 ± 5.4 mV P = NS. CONCLUSIONS: There is no difference in the detection of VF between EBP or TBP configurations in patients undergoing ICD implantation.

An athletic 43-year-old man presented with symptomatic bradycardia and atrial flutter after being diagnosed with HLA B27 associated spondyloarthropathy several months earlier. The patient was admitted and underwent electrophysiology evaluation with ablation of his atrial flutter and eventually underwent pacemaker implantation. His cardiac workup showed a structurally normal heart and strongly suggested that his HLA B27 associated spondyloarthropathy was responsible for his presentation. A review of the literature suggests that HLA B27 spondyloarthropathy related heart block may be an often overlooked cause of heart block in otherwise healthy patients.

Biatrial flutter is a rare form of macro-reentrant atrial tachycardia that involves both the right and left atria. Single-loop biatrial flutter is typically associated with scarring of the septum from prior ablation or surgery and is generally made up of two interatrial connections-that is, the coronary sinus and Bachmann's bundle. Entrainment and high-density mapping allow for rapid diagnosis and development of a treatment strategy. Ablation planning should also take into consideration the preservation of interatrial conduction. We herein discuss a case of single-loop biatrial flutter presenting as a typical atrial flutter and review the differential diagnosis and physiology of the arrhythmia.
