Evaluation of Pericardial Effusions in Alopecia Patients on Low-Dose Oral Minoxidil Therapy.

BACKGROUND: Minoxidil is an anti-hypertensive vasodilator increasingly used off-label for the treatment of alopecia. It is associated with an increased risk of pericardial effusions, with recent reports even in patients on low-dose oral minoxidil (LDOM) therapy. OBJECTIVE: To evaluate whether LDOM is associated with increased prevalence of pericardial effusions in patients with alopecia. METHODS: In this cross-sectional study, point-of-care ultrasound was used to screen alopecia patients at dermatology appointments. Scans were evaluated by two independent cardiologists for the presence and size of effusions. The prevalence of effusions was compared between patients on LDOM therapy and patients not on minoxidil therapy. RESULTS: A total of 100 patients were evaluated for pericardial effusion: 51 LDOM patients and 49 control patients. The two groups were similar in terms of age (53.7 vs 54.1; P=0.91), sex (86% vs 73% female; P=0.14), and race. Small pericardial effusions (<1 cm) were identified in 5.8% of LDOM patients and 6% of control patients (P=1), none of which were symptomatic. LIMITATIONS: This is a small, cross-sectional study with limitations on speculation of causality in confirmed cases. CONCLUSION: We did not find evidence of increased prevalence of pericardial effusions in a small group of alopecia patients on LDOM. J Drugs Dermatol. 2024;23(9):725-728. doi:10.36849/JDD.8029.

Prognostic Utility of Pericardial Effusion in the General Population: Findings From the STAAB Cohort Study.

BACKGROUND: The incidental finding of a pericardial effusion (PE) poses a challenge in clinical care. PE is associated with malignant conditions or severe cardiac disease but may also be observed in healthy individuals. This study explored the prevalence, determinants, course, and prognostic relevance of PE in a population-based cohort. METHODS AND RESULTS: The STAAB (Characteristics and Course of Heart Failure Stages A/B and Determinants of Progression) cohort study recruited a representative sample of the population of Würzburg, aged 30 to 79 years. Participants underwent quality-controlled transthoracic echocardiography including the dedicated evaluation of the pericardial space. Of 4965 individuals included at baseline (mean age, 55±12 years; 52% women), 134 (2.7%) exhibited an incidentally diagnosed PE (median diameter, 2.7 mm; quartiles, 2.0-4.1 mm). In multivariable logistic regression, lower body mass index and higher NT-proBNP (N-terminal pro-B-type natriuretic peptide) levels were associated with PE at baseline, whereas inflammation, malignancy, and rheumatoid disease were not. Among the 3901 participants attending the follow-up examination after a median time of 34 (30-41) months, PE was found in 60 individuals (1.5%; n=18 new PE, n=42 persistent PE). Within the follow-up period, 37 participants died and 93 participants reported a newly diagnosed malignancy. The presence of PE did not predict all-cause death or the development of new malignancy. CONCLUSIONS: Incidental PE was detected in about 3% of individuals, with the vast majority measuring <10 mm and completely resolving. PE was not associated with inflammation markers, death, incident heart failure, or malignancy. Our findings corroborate the view of current guidelines that a small PE in asymptomatic individuals can be considered an innocent phenomenon and does not require extensive short-term monitoring.

Descriptions of Etiology, Clinical Course, and Prognosis of Patients Presenting with Pericardial Effusion.

Pericardial effusion (PE) presentation varies from an incidental finding to a life-threatening situation; thus, its etiology and clinical course remain unknown. The aim of the present study was to retrospectively investigate these factors.We analyzed 171 patients (0.4%) who presented with PE among 34,873 patients who underwent echocardiography between 2011 and 2021 at our hospital. Clinical and prognostic information was retrieved from electronic medical records. The primary endpoints were all-cause death, hospitalization due to heart failure (HF), and other cardiovascular events such as cardiovascular death, acute coronary syndrome, elective percutaneous coronary intervention, and stroke.The etiologies of PE were as follows: idiopathic (32%), HF-related (18%), iatrogenic (11%), cardiac surgery-related (10%), radiation therapy-related (9%), malignancy (8%), pericarditis/myocarditis (8%), myocardial infarction-related (2%), and acute aortic dissection (2%). Patients with idiopathic/HF etiology were more likely to be older than the others.During a mean follow-up period of 2.5 years, all-cause death occurred in 21 patients (12.3%), cardiovascular events in 10 patients (5.8%), and hospitalization for HF in 24 patients (14.0%). All-cause death was frequently observed in patients with malignancy (44% per person-year). Cardiovascular events were mostly observed in patients with radiation therapy-related and malignancy (8.6% and 7.3% per person-year, respectively).The annual incidence of hospitalization for HF was the highest in patients with HF-related (25.1% per person-year), followed by radiation therapy-related (10.4% per person-year).This retrospective study is the first, to the best of our knowledge, to reveal the contemporary prevalence of PE, its cause, and outcome in patients who visited a cardiovascular hospital in an urban area of Japan.

Risk factors and outcomes of pericardial effusion in cancer patients receiving PD-1 inhibitors.

BACKGROUND: Programmed cell death 1 (PD-1) inhibitors can induce various adverse reactions associated with immunity, of which cardiotoxicity is a serious complication. Limited research exists on the link between PD-1 inhibitor use and pericardial effusion (PE) occurrence and outcomes. METHODS: We conducted a retrospective study at the First Affiliated Hospital of Xi'an Jiaotong University from 2017 to 2019, comparing cancer patients who developed PE within 2 years after PD-1 inhibitor therapy to those who did not. Our primary outcome was the all-cause mortality rate at one year. We applied the Kaplan-Meier method for survival analysis. Multivariate logistic regression was utilized to identify PE risk factors, adjusting for potential confounders. RESULTS: A total of 91 patients were finally included, of whom 39 patients had PE. Compared to non-PE group, one-year all-cause mortality was nearly 5 times higher in PE group (64.10% vs. 13.46%, P < 0.001). Patients who developed PE within 2 years of taking PD-1 inhibitors were significantly associated with increased all-cause mortality compared with those who did not (HR: 6.26, 95%CI: 2.70-14.53, P < 0.001). Multivariable logistic regression showed that use of sintilimab (OR: 14.568, 95%CI: 3.431-61.857, P < 0.001), history of lung cancer (OR: 15.360, 95%CI: 3.276-72.017, P = 0.001), and history of hypocalcemia (OR: 7.076, 95%CI: 1.879-26.649, P = 0.004) were independent risk factors of PE development in patients received PD-1 inhibitors therapy. CONCLUSIONS: In cancer patients receiving PD-1 inhibitors, PE was associated with higher one-year mortality. Use of sintilimab, and history of lung cancer or hypocalcemia were linked to PE occurrence.

Pericardiotomy and atrial fibrillation after isolated coronary artery bypass grafting: A systematic review and meta-analysis of 16 randomised controlled trials.

BACKGROUND: Atrial fibrillation (AF) and pericardial effusion are notable complications following coronary artery bypass grafting (CABG), contributing to increased morbidity and healthcare costs. Posterior pericardiotomy has been proposed to mitigate these complications. This systematic review and meta-analysis aim to evaluate the efficacy of posterior pericardiotomy in reducing postoperative AF and pericardial effusion in isolated CABG patients. MATERIALS AND METHODS: A comprehensive literature search, adhering to PRISMA guidelines, was conducted across PubMed, MEDLINE via Ovid, Embase, Scopus, the Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov up to December 2023. Only randomised controlled trials (RCTs) comparing prophylactic posterior pericardiotomy to control treatments in adult CABG patients were included. The primary outcomes assessed were the incidences of postoperative AF and pericardial effusion. RESULTS: The meta-analysis incorporated 16 RCTs with a total of 2414 patients. The findings demonstrated a significant reduction in the incidence of postoperative AF (Odds Ratio = 0.34, 95 % CI: 0.25-0.48, P < 0.00001) and pericardial effusion (Odd Ratio = 0.24, 95 % CI: 0.15-0.38, P < 0.0001) in the group undergoing posterior pericardiotomy. However, the analysis revealed substantial heterogeneity and publication bias in the included studies. CONCLUSION: The posterior pericardiotomy is effective in reducing the incidences of AF and pericardial effusion in patients undergoing isolated CABG. Despite the positive outcomes, the presence of heterogeneity and publication bias warrants a cautious interpretation of the results and underscores the need for further multicentre RCTs in this area.

Cardiac evaluation in pregnant patients with dyspnea and palpitations.

BACKGROUND: Symptoms of underlying cardiac disease in pregnancy can often be mistaken for common complaints because of normal physiological changes in pregnancy. Echocardiographic evaluation of patients with symptoms of palpitations and dyspnea can detect structural changes and identify high-risk features. OBJECTIVE: This study aimed to examine transthoracic echocardiograms of perinatal individuals completed for palpitations or dyspnea to determine the frequency of identifying structural changes. STUDY DESIGN: This was a retrospective cohort study of all perinatal individuals with a transthoracic echocardiogram at a single academic center between October 1, 2017, and May 1, 2022. The indication for the echocardiogram, demographics, and clinical characteristics were recorded. Transthoracic echocardiograms with any abnormal findings noted in the transthoracic echocardiogram report were reviewed and categorized into findings of congenital heart disease, valvular disease, pericardial effusion, evidence of ischemia or wall motion abnormalities, abnormal diastolic or systolic function, and other. RESULTS: Of 539 transthoracic echocardiograms completed on 478 individuals who were pregnant or in the 12-week postpartum period, 96 (17.8%) had an indication of palpitations, and 32 (5.9%) had an indication of dyspnea. Abnormal findings were seen in 21.9% of patients with palpitations and in 34.4% of patients with dyspnea. In patients with palpitations who had abnormal findings, 33.3% had congenital heart disease; 33.3% had mild valvular disease, including mitral valve prolapse; 19.0% had a pericardial effusion; and 14.3% had evidence of ischemia or wall motion defects. Abnormal transthoracic echocardiogram findings in the dyspnea cohort included ischemia or wall motion defects (27.3%), mild valvular disease or mitral valve prolapse (36.4%), and abnormal systolic or diastolic function (36.4%). CONCLUSION: Many of the transthoracic echocardiograms completed for patients with dyspnea or palpitations identified no structural abnormality; however, in 1 of 3 to 1 of 4 patients, underlying structural heart disease was identified. Although some of these abnormalities were unlikely to change delivery plans, such as mild valvular disease or small effusions, other abnormalities, such as ischemia, congenital abnormalities, and abnormal systolic or diastolic function, were likely to have implications for pregnancy and postpartum management.

Pericardiocentesis versus window formation in malignant pericardial effusion: trends and outcomes.

OBJECTIVES: Malignant pericardial effusion (MPE) in patients with cancer is associated with poor prognosis. This study aimed to compare clinical outcomes in patients with cancer who underwent pericardiocentesis versus pericardial window formation. METHODS: In the present study, 765 consecutive patients with cancer (mean age 58.4 years, 395 men) who underwent pericardial drainage between 2003 and 2022 were retrospectively analysed. All-cause death and MPE recurrence were compared based on the drainage method (pericardiocentesis vs pericardial window formation) and time period (period 1: 2003-2012; period 2: 2013-2022). RESULTS: Pericardiocentesis was performed in 639 (83.5%) patients and pericardial window formation in 126 (16.5%). There was no difference in age, sex distribution, proportion of metastatic or relapsed cancer, and chemotherapy status between the pericardiocentesis and pericardial window formation groups. Difference was not found in all-cause death between the two groups (log-rank p=0.226) regardless of the period. The pericardial window formation group was associated with lower MPE recurrence than the pericardiocentesis group (6.3% vs 18.0%, log-rank p=0.001). This advantage of pericardial window formation was more significant in period 2 (18.1% vs 1.3%, log-rank p=0.005). In multivariate analysis, pericardial window formation was associated with lower MPE recurrence (HR: 0.31, 95% CI: 0.15 to 0.63, p=0.001); younger age, metastatic or relapsed cancer, and positive malignant cells in pericardial fluid were associated with increased recurrence. CONCLUSION: In patients undergoing pericardial drainage for MPE, pericardial window formation showed mortality outcomes comparable with pericardiocentesis and was associated with lower incidence of MPE recurrence.

Pericardial effusion in children at tertiary national referral hospital, Addis Ababa, Ethiopia: a 7-year institution based review.

BACKGROUND: Pericardial effusion (PE) is a rare yet an important cause of child mortality due to collection of excess fluid in pericardial space. The study aimed to describe the PE profile in the national cardiac referral hospital, Addis Ababa, Ethiopia. METHODS: The study employed cross-sectional study design for a 7-year review of childhood PE in Tikur Anbessa Specialized Hospital. Descriptive and analytic statistics were applied. RESULTS: There were 17,386 pediatric emergency/ER admissions during the study period, and PE contributed to 0.47% of ER admissions. From 71 included subjects, 59% (42) were males with mean age of 7.8 ± 3.3 years. Cough or shortness of breath,73.2% (52) and fever or fast breathing, 26.7% (19), were the common presenting symptoms. The median duration of an illness before presentation was 14days (IQR: 8-20). The etiologies for pericardial effusion were infective (culture positive-23.9%, culture negative-43.6%, tuberculous-4.2%), hypothyroidism (4.2%), inflammatory (12.7%), malignancy (7%) or secondary to chronic kidney disease (1. 4%). Staphylococcus aureus was the most common isolated bacteria on blood culture, 12.7% (9) while the rest were pseudomonas, 7% (5) and klebsiella, 4.2% (3). Mild, moderate and severe pericardial effusion was documented in 22.5% (16), 46.5% (33), and 31% (22) of study subjects, respectively. Pericardial tamponade was reported in 50.7% (36) of subjects. Pericardial drainage procedure (pericardiocentesis, window or pericardiotomy) was performed for 52.1% (37) PE cases. The case fatality of PE was 12.7% (9). Pericardial drainage procedure was inversely related to mortality, adjusted odds ratio 0.11(0.01-0.99), p 0.049). CONCLUSION: PE contributed to 0.47% of ER admissions. The commonest PE presentation was respiratory symptoms of around two weeks duration. Purulent pericarditis of staphylococcal etiology was the commonest cause of PE and the case fatality rate was 12.7%. Pericardial drainage procedures contributed to reduction in mortality. All PE cases should be assessed for pericardial drainage procedure to avoid mortality.

Pericarditis After Catheter Ablation for Atrial Fibrillation: Predictors and Outcomes.

BACKGROUND: Catheter ablation is a mainstay of atrial fibrillation (AF) treatment. Acute pericarditis after ablation is 1 of the frequently observed complications. There is a significant lack of data on the incidence and predictors of postablation pericarditis. OBJECTIVES: This study examines the incidence, characteristics, and predictors of pericarditis after AF ablation. METHODS: Patients undergoing AF ablation from January 1, 2016, to March 31, 2022, at Johns Hopkins were prospectively enrolled in an AF ablation registry. A clinical diagnosis of acute pericarditis was established in accordance with 2015 European Society of Cardiology guidelines by the presence of at least 2 of the following characteristics: pleuritic chest pain, friction rub, typical electrocardiographic changes, or pericardial effusion within 3 months after the ablation procedure. RESULTS: Of 1,540 patients who underwent AF ablation, 57 patients (3.7%) developed acute pericarditis. Baseline clinical characteristics including age, sex, and body mass index were comparable between the pericarditis and nonpericarditis groups. The median time to symptom onset was 1 day. Electrocardiographic changes were observed in 34 (59.6%) patients, pericardial effusion developed in 7 (12%) patients, and the mean duration of medical treatment was 7 days (25th-75th percentile: 3-14 days). Most pericarditis cases were treated medically with disease-specific nonsteroidal anti-inflammatory drugs (100%) and colchicine (81%). Effusion with tamponade necessitating pericardiocentesis was observed in 4 (7%) patients. Radiofrequency (RF) ablation was performed in 869 (58.6%) patients in the nonpericarditis group and 39 (68.4%) patients with pericarditis; cryoballoon ablation was performed in 486 (32.8%) patients in the nonpericarditis group and 11 (19.3%) patients with pericarditis. Multivariable logistic regression analysis identified RF ablation (OR: 2.09; 95% CI: 1.07-4.08; P = 0.03) as an independent predictor of acute pericarditis after AF ablation, whereas age per unit increase was associated with a decreased risk (OR: 0.97; 95% CI: 0.95-0.995; P = 0.02). CONCLUSIONS: The incidence of acute pericarditis after catheter ablation in our study population was 3.7%. RF ablation and younger age were independent risk factors for postablation acute pericarditis.

Echocardiographic Findings of Malignant Lymphoma with Cardiac Involvement: A Single-center Retrospective Observational Study.

Objective Although malignant lymphoma (ML) can occur in every organ, diagnosing cardiac involvement without cardiac manifestations is difficult. We therefore investigated the incidence of cardiac involvement in ML in our hospital and clarified the transthoracic echocardiography (TTE) findings of cardiac involvement. Methods Patients with ML referred to our hospital between January 2013 and December 2019 were retrospectively reviewed. Patients During the study period, 453 patients were identified. The mean age was 64.9 years old, and 54% of the patients were men. Results Diffuse large B-cell lymphoma (DLBCL) was the most common lymphoma, followed by follicular lymphoma. Of the 453 patients, 394 (87.0%) underwent TTE at the initial diagnosis or during the clinical course. The performance rates of TTE in DLBCL, Hodgkin lymphoma, and mantle cell lymphoma were above 90%. Cardiac involvement was detected in 6 (five with DLBCL and one with B-cell lymphoma) (1.5%) of the 394 patients who underwent TTE. The involved lesions of the heart varied, and five patients had pericardial effusion. Five patients had a preserved left ventricular ejection fraction. All patients were treated with chemotherapy, and some were treated with radiation and surgery. Conclusion Cardiac involvement was observed in six (1.5%) of the patients with ML who underwent TTE. B-cell lymphoma, especially DLBCL, is a common ML with cardiac involvement. Although five patients had pericardial effusion, the involved lesions of the heart were not uniform. TTE is a useful imaging modality to noninvasively and repeatedly evaluate the tumor characteristics, response to ML treatment, and cardiac function.

Cardiovascular comorbidities and their prognostic value in small cell lung cancer patients with chemoradiotherapy.

BACKGROUND: Small cell lung cancer (SCLC) is an extremely malignant subtype of lung cancer because of its high potential for metastases. Cardiac invasion of SCLC is a serious concern that may lead to systemic embolism or tract obstruction. It has aroused much concern that cardiovascular comorbidities may significantly affect the survival of SCLC patients and their treatment decisions. METHODS: We consecutively recruited 772 small cell lung cancer (SCLC) patients between January 2011 and December 2018 from 4 cancer specialty hospitals in China. Only newly diagnosed primary cancer inpatients were included. Univariable and multivariable adjusted Cox proportional hazard models were conducted to evaluate the risk factors associated with mortality. Hazard ratios (HRs) for mortality and corresponding 95% confidence intervals (95% CIs) were calculated. RESULTS: The prevalence of cardiovascular diseases (CVDs) was 34.6% in all SCLC patients. Log-rank analysis presented statistically significant differences in median survival time (MST) between patients with CVD and without CVD in all SCLC patients (9.0 months vs. 15.0 months, P = 0.005) and patients with chemotherapy only (12.0 months vs. 18.0 months, P = 0.048). Pericardial effusion (HR 1.671, 95% CI 1.082-2.580, P = 0.021) and heart failure (HR 1.752, 95% CI 1.290-2.379, P < 0.001) were independent risk factors associated with mortality in all SCLC patients. VTE is related to poorer prognosis in patients with chemotherapy only (HR 5.558, 95% CI 1.335-23.135, P = 0.018) and chemoradiotherapy (HR 3.057, 95% CI 1.270-7.539, P = 0.013). CONCLUSIONS: Comprehensive management of CVD comorbidities is of vital importance for the long-term prognosis of SCLC patients.

Pericardial Effusion Predicts Clinical Outcomes in Patients with COVID-19: A Nationwide Multicenter Study.

RATIONALE AND OBJECTIVES: The prognostic role of pericardial effusion (PE) in Covid 19 is unclear. The aim of the present study was to estimate the prognostic role of PE in patients with Covid 19 in a large multicentre setting. MATERIALS AND METHODS: This retrospective study is a part of the German multicenter project RACOON (Radiological Cooperative Network of the Covid 19 pandemic). The acquired sample comprises 1197 patients, 363 (30.3%) women and 834 (69.7%) men. In every case, chest computed tomography was analyzed for PE. Data about 30-day mortality, need for mechanical ventilation and need for intensive care unit (ICU) admission were collected. Data were evaluated by means of descriptive statistics. Group differences were calculated with Mann-Whitney test and Fisher exact test. Uni-and multivariable regression analyses were performed. RESULTS: Overall, 46.4% of the patients were admitted to ICU, mechanical lung ventilation was performed in 26.6% and 30-day mortality was 24%. PE was identified in 159 patients (13.3%). The presence of PE was associated with 30-day mortality: HR= 1.54, CI 95% (1.05; 2.23), p = 0.02 (univariable analysis), and HR= 1.60, CI 95% (1.03; 2.48), p = 0.03 (multivariable analysis). Furthermore, density of PE was associated with the need for intubation (OR=1.02, CI 95% (1.003; 1.05), p = 0.03) and the need for ICU admission (OR=1.03, CI 95% (1.005; 1.05), p = 0.01) in univariable regression analysis. The presence of PE was associated with 30-day mortality in male patients, HR= 1.56, CI 95%(1.01-2.43), p = 0.04 (multivariable analysis). In female patients, none of PE values predicted clinical outcomes. CONCLUSION: The prevalence of PE in Covid 19 is 13.3%. PE is an independent predictor of 30-day mortality in male patients with Covid 19. In female patients, PE plays no predictive role.

Retrospective study of risk factors for pericardial effusion after haematopoietic stem cell transplantation in children.

OBJECTIVES: The clinical characteristics, risk factors and survival prognosis of pericardial effusion (PE) after haematopoietic stem cell transplantation (HSCT) in children were investigated. METHODS: Clinical data of children who underwent HSCT at the Children's Hospital Affiliated with Chongqing Medical University from January 2016 to December 2022 were analysed retrospectively. Cox proportional hazards regression and the Kaplan-Meier method were used to analyse the risk factors for post-HSCT PE and its impact on outcomes, respectively. RESULTS: We enrolled 452 patients with HSCT: 307 males and 145 females, with a median age of 3.4 (1.8 to 6.5) years at transplantation. Forty-five patients (10%) had PE within a median time of 25 (10.5 to 44) days, 42 (93%) within 100 days. Three patients with large PE were treated with pericardiocentesis and drainage, while the others were treated conservatively. Of the 45 patients with PE, 24 survived, and their PE disappeared after treatment. Graft-versus-host disease (GVHD) grade, abnormal pre-HSCT electrocardiogram, hepatic veno-occlusive disease (HVOD), pulmonary infection and Epstein-Barr virus (EBV) infection were risk factors for PE. The overall survival (OS) rates at 1, 3, and 5 years were 86.0%, 84.2%, and 82.3%, respectively. PE had a significant negative effect on OS after HSCT (P < 0.0001). Particularly, one patient with large PE died of pericardial tamponade. CONCLUSIONS: Post-HSCT PE usually occurred within 100 days. GVHD grade, abnormal pre-HSCT electrocardiogram, HVOD, pulmonary infection and EBV infection were closely related to PE. PE had a significant negative effect on OS rate.

Safety and efficacy of ablation for atrial fibrillation in combination with left atrial appendage occlusion in octogenarians.

BACKGROUND: Catheter ablation (CA) combined with left atrial appendage occlusion (LAAO) is a feasible approach for atrial fibrillation (AF) patients. Its role in octogenarians with AF is unclear. HYPOTHESIS: In AF patients over 80 years, CA combined with LAAO is a feasible way in restoring sinus rhythm and preventing stroke. METHODS: This is a single-center retrospective study. Patients who underwent CA and LAAO in a single procedure between March 2018 and December 2020 were included. Efficacy endpoints included procedural success rate, AF recurrence rate, and thromboembolic events. Safety endpoints included pericardial effusion/cardiac tamponade, device-related thrombus (DRT), all-cause death, and major bleeding. RESULTS: Five hundred and five patients (mean age 69.5 ± 7.7 years; 230 [45.5%] female) were included, with 46 (9.1%) patients aged ≥80 years old (octogenarian group). Prevalence of paroxysmal AF (25 [54.3%] vs. 207 [45.1%], p < 0.001) and CHA2DS2VASc score (4.1 ± 1.3 vs. 3.1 ± 1.4, p < 0.0001) were higher in octogenarian patients. There were six cases (1.2%) of pericardial effusion (all in nonoctogenarian patients). At 3 months postprocedure, 437 patients underwent TEE/CT. Thirty-two (80%) octogenarian patients and 308 (77.6%) nonoctogenarian patients had no peri-device leak. After a mean follow-up of 26.9 ± 9.1 months, AF was documented in 10 (21.7%) patients in octogenarian group and in 103 (22.4%) patients in nonoctogenarian group (p = 0.99). The annual thromboembolic risk was 2.1% and 0.8% in the octogenarian group and nonoctogenarian group, respectively. Death occurred in 16 nonoctogenarian patients. One major bleeding was recorded in the octogenarian group. CONCLUSIONS: The combination of CA and LAAO in a single procedure is a feasible treatment option in octogenarians with comparable efficacy and safety profile.

Outcomes of Valvular Endocarditis in Patients With and Without Pericardial Effusion: A National Inpatient Sample Study.

Over the last decade, hospitalizations for infective endocarditis (IE) have been steadily increasing, leading to a significant healthcare burden. Pericardial effusion (PCE) has been identified as a serious complication of IE, yet no significant association with mortality has been established. Our study aims to further analyze and understand the significance of PCE in patients with IE. We performed a retrospective analysis using the national inpatient sample database to identify all the hospital admissions with IE using ICD 10 codes and stratified them into 2 groups based on the presence of PCE. The outcomes of interest were inhospital mortality, inhospital complications, need for cardiac surgery, and length of stay. From 2015 Q4-2019, a total of 76,260 hospitalizations were included (weighted: 381,300), of which 2.7% included a PCE diagnosis. Hospitalizations with a PCE diagnosis included patients that were younger (51 vs 61, P < 0.001), as well as slightly more males (58.0% vs 55.2%, P = 0.011), and black patients (16.9% vs 12.9%, P < 0.001). PCE was associated with higher in-hospital death (12.7% vs 9.0%, P < 0.001), longer lengths of stay (12 days vs 7 days, P < 0.001), higher rates of cardiac surgery (22.4% vs 7.3%, P < 0.001). The rates of heart failure, heart block, renal failure, cardiogenic shock, and embolic stroke were higher on PCE group. We found that presence of PCE is associated with higher inhospital mortality, longer length of stay, and greater utilization of cardiac surgery, as well as presence of heart failure, heart block, cardiogenic shock, and embolic stroke.

Colchicine usage for prevention of post atrial fibrillation ablation pericarditis in patients undergoing high-power short-duration ablation.

INTRODUCTION: Radiofrequency ablation (RFA) for atrial fibrillation (AF) has been associated with variable incidence (0.88%-10%) of pericarditis manifested as chest pain, possibly more prevalent with the advent of high-power short-duration (HPSD) ablation. This has led to the widespread use of colchicine in preventative protocols for postablation pericarditis. However, the efficacy of preventative colchicine has not been validated yet. OBJECTIVE: To evaluate the efficacy of a routine postoperative colchicine regimen (0.6 mg twice a day for 14 days post-AF ablation) for prevention of postablation pericarditis in patients undergoing HPSD ablation. METHOD: We retrospectively evaluated consecutive single-operator HPSD AF ablation procedures at our institution from June 2019 to July 2022. A colchicine protocol was introduced in June 2021 for the prevention of postablation pericarditis. All ablations were performed with 50 watts. Patients were divided into colchicine and noncolchicine groups. We recorded incidence of postablation chest pain, emergency room (ER) visit for chest pain, pericardial effusion, pericardiocentesis, any ER visit, hospitalization, AF recurrence, and cardioversion for AF within the first 30 days following ablation. We also recorded colchicine-related side effects and medication compliance. RESULTS: Two hundred and ninety-four consecutive HPSD AF ablation patients were screened for the study. After implementing the prespecified exclusion criteria, a total of 205 patients were included in the final analysis, yielding 101 patients in the colchicine group and 104 patients in the noncolchicine group. Both groups were well-matched for demographic and procedural parameters. There was no significant difference in postablation chest pain (9.9% vs. 8.6%, p = .7), pericardial effusion (2.9% vs. 0.9%, p = .1), ER visits (11.9% vs. 12.5%, p = .2), 30-day hospitalization for AF recurrence (0.9% vs. 0.96%, p = .3), and 30-day need for cardioversion for AF (3.9% vs. 5.7%, p = .2). Fifteen (15) patients had severe colchicine-related diarrhea, out of which 12 discontinued it prematurely. There were no major procedural complications in either group. CONCLUSION: In this single-operator retrospective analysis, prophylactic colchicine was not associated with significant reduction in the incidence of postablation chest pain, pericarditis, 30 day hospitalization, ER visits, or AF recurrence or need of cardioversion within first 30 days after HPSD ablation for AF. However, its usage was associated with significant diarrhea. This study concludes no additional advantage of prophylactic use of colchicine after HPSD AF ablation.

Toxic Effects of Volume-modulated Arc Therapy for Esophageal Squamous Cell Cancer: Preliminary Clinical Results.

BACKGROUND/AIM: To evaluate the toxic effects associated with various factors, including the presence or absence of concurrent chemotherapy with volume-modulated arc therapy (VMAT) and dose parameters for esophageal cancer (EC), and to assess the safety and feasibility of the VMAT protocol. PATIENTS AND METHODS: Patients with EC who received definitive VMAT between December 2016 and December 2020 were retrospectively analyzed. VMAT plans were designed to deliver 60 Gy to the primary tumor, 54 Gy to high-risk sites, and 51.3 Gy to regional lymph node sites. Toxic effects were evaluated for esophagitis, neutropenia, esophageal stricture, pericardial effusion, radiation-associated pneumonia. RESULTS: Forty-five patients received concurrent chemoradiotherapy (CCRT), while 29 were treated with radiation therapy (RT) alone. The following grade 3 complications were detected: Neutropenia in four patients (5.4%), esophagitis in two (2.7%), and esophageal stricture in one (1.4%). Grade 4 or more complications were not observed. The median age of the CCRT group (67 years) was significantly lower than that of the RT-alone group (77 years) (p<0.0001). The incidence of esophagitis was significantly higher in the CCRT group (75.5%) than in the RT group (48.3%) (p=0.033). The univariate analysis identified increasing mean dose to the pericardium as a significant risk factor for pericardial effusion, and CCRT and performance status ≥1 as significant for radiation-associated pneumonia. These factors were not significant in the multivariate analysis. Neutropenia and esophageal stricture were not associated with any factor examined. CONCLUSION: VMAT alone and in CCRT performed with our protocol was safe and feasible in patients with esophageal squamous cell cancer.

Profile of Cardiac Involvement in Children After Exposure to COVID-19.

OBJECTIVE: To evaluate the incidence and pattern of cardiac involvement in children post-COVID (coronavirus disease) infection in a tertiary care referral hospital in India. METHODS: A prospective observational study was conducted including all consecutive children with suspected MIS-C referred to the cardiology services. RESULTS: Of the 111 children with mean (SD) age was 3.5 (3.6) years, 95.4% had cardiac involvement. Abnormalities detected were coronary vasculopathy, pericardial effusion, valvular regurgitation, ventricular dysfunction, diastolic flow reversal in aorta, pulmonary hypertension, bradycardia and intra-cardiac thrombus. The survival rate post treatment was 99%. Early and short-term follow-up data was available in 95% and 70%, respectively. Cardiac parameters improved in majority. CONCLUSION: Cardiac involvement post COVID-19 is often a silent entity and may be missed unless specifically evaluated for. Early echocardiography aided prompt diagnosis, triaging, and treatment, and helps in favorable outcomes.

Pericardial Effusions After the Arterial Switch Operation: A PHIS Database Review.

Background: Pericardial effusion (PCE) is a significant complication after pediatric cardiac surgery. This study investigates PCE development after the arterial switch operation (ASO) and its short-term and longitudinal impacts. Methods: A retrospective review of the Pediatric Health Information System database. Patients with dextro-transposition of the great arteries who underwent ASO from January 1, 2004, to March 31, 2022, were identified. Patients with and without PCE were analyzed with descriptive, univariate, and multivariable regression statistics. Results: There were 4896 patients identified with 300 (6.1%) diagnosed with PCE. Thirty-five (11.7%) with PCE underwent pericardiocentesis. There were no differences in background demographics or concomitant procedures between those who developed PCE and those who did not. Patients who developed PCE more frequently had acute renal failure (N = 56 (18.7%) vs N = 603(13.1%), P = .006), pleural effusions (N = 46 (15.3%) vs N = 441 (9.6%), P = .001), mechanical circulatory support (N = 26 (8.7%) vs N = 199 (4.3%), P < .001), and had longer postoperative length of stay (15 [11-24.5] vs 13 [IQR: 9-20] days). After adjustment for additional factors, pleural effusions (OR = 1.7 [95% CI: 1.2-2.4]), and mechanical circulatory support (OR = 1.81 [95% CI: 1.15-2.85]) conferred higher odds of PCE. There were 2298 total readmissions, of which 46 (2%) had PCE, with no difference in median readmission rate for patients diagnosed with PCE at index hospitalization (median 0 [IQR: 0-1] vs 0 [IQR: 0-0], P = .208). Conclusions: PCE occurred after 6.1% of ASO and was associated with pleural effusions and mechanical circulatory support. PCE is associated with morbidity and prolonged length of stay; however, there was no association with in-hospital mortality or readmissions.
