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.

Significance of medical intervention for non-traumatic hemorrhagic cardiac tamponade.

BACKGROUND: The outcomes of patients with cardiac arrest induced by non-traumatic hemorrhagic cardiac tamponade are poor. PURPOSE: We retrospectively investigated the significance of medical intervention with pericardiocentesis and/or pericardiotomy for non-traumatic hemorrhagic cardiac tamponade. METHODS: From January 2013 to April 2021, we retrospectively reviewed the medical charts of all patients with cardiac arrest in a prehospital setting or emergency room due to cardiac tamponade confirmed by an ultrasound examination with or without an invasive procedure (pericardiocentesis and/or pericardiotomy) and computed tomography findings, including those obtained at autopsy imaging. The subjects were divided into two groups: the Intervention (+) group, which included subjects who underwent pericardiocentesis or pericardiotomy, and the Intervention (-) group, which included subjects who did not undergo pericardiocentesis or pericardiotomy. Variables were then compared between the two groups. RESULTS: There were 68 patients with non-traumatic cardiac tamponade. All three survival cases had witnessed collapse, and the initial rhythm was pulseless electrical activity (PEA).There were no statistically significant differences in the sex, age, means of transportation, bystander chest compression, electric shock, or adrenalineor FDP levels between the two groups.However, the number with witnessed collapse, PEA, rupture of the heart;the ratio of obtaining return of spontaneous circulation; and the survival ratio were significantly greater in the Intervention (+) group than in the Intervention (-) group. CONCLUSION: Based on the results of preliminary study, we hypothesized that invasive medical intervention for patients with cardiac arrest induced by non-traumatic hemorrhagic cardiac tamponade might be useful for obtaining return of spontaneous circulation and a survival outcome, especially for patients with witnessed collapse with PEA as the initial rhythm.

Prognosis and role of clinical and imaging features in patients with malignant pericardial effusion: a single-center study in China.

BACKGROUND: The diagnosis of malignant pericardial effusion (MPE) is often associated with a poor prognosis, but due to the complexity and unspecific nature of MPE patients' clinical manifestations, imaging often performs an essential role in diagnosis and prognosis. METHODS: Patients diagnosed with MPE between 2013 and 2018 at one tumor hospital were included and followed up. The data covered the basic clinical features, imaging findings, treatments and prognosis of patients with MPE, and the factors that may have affected the prognosis were explored. RESULTS: A total of 216 patients with MPE were included with the median age of 60 years. The most common primary cancer type was lung cancer (73.6%), the most common symptom was dyspnea (62.9%) and the most common abnormal electrocardiogram finding was sinus tachycardia (42.1%). The median survival time of the 216 patients with MPE was 13.7 months. The factors affecting prognosis were echocardiographic fluid signs (HR = 2.37, P = 0.010), electrocardiographic evidence of sinus tachycardia (HR = 1.76, P = 0.006) and echocardiographic evidence of cardiac tamponade (HR = 3.33, P < 0.001). CONCLUSIONS: MPE has complex clinical manifestations and an unsatisfactory prognosis. Echocardiographic fluid signs, electrocardiographic evidence of sinus tachycardia, and echocardiographic evidence of cardiac tamponade are independent risk factors affecting prognosis.

Pericardial Effusion and Cardiac Tamponade: Etiology and Evolution in the Contemporary Era

Abstract Background: Pericardial effusion is a relatively common finding and can progress to cardiac tamponade; etiological diagnosis is important for guiding treatment decisions. With advances in medicine and improvement in the social context, the most frequent etiological causes have changed. Objectives: To evaluate the clinical and laboratory characteristics, etiology, and clinical course of patients with pericardial effusion and cardiac tamponade. Materials and methods: Patients with pericardial effusion classified as small (< 10 mm), moderate (between 10-20 mm), or severe (> 20 mm) were included. Data from the clinical history, physical examination, laboratory tests, and complementary tests were evaluated in patients with pericardial effusion and cardiac tamponade. The significance level was set at 5%. Results: A total of 254 patients with a mean age of 53.09 ± 17.9 years were evaluated, 51.2% of whom were female. A total of 40.4% had significant pericardial effusion (> 20 mm). Pericardial tamponade occurred in 44.1% of patients. Among pericardial effusion patients without tamponade, the most frequent etiologies were: idiopathic (44.4%) and postsurgical (17.6%), while among those with tamponade, the most frequent etiologies were postsurgical (21.4%) and postprocedural (19.6%). The mean follow-up time was 2.2 years. Mortality was 42% and 23.2 in those with and without tamponade, respectively (p=0.001). Conclusions: There is an etiological difference between pericardial effusion patients with and without cardiac tamponade. An idiopathic etiology is more common among those without tamponade, while postinterventional/postsurgical is more common among those with tamponade. The tamponade group had a higher mortality rate.

Intrapericardial instillation of bleomycin prevents recurrence of malignant pericardial effusions: Series of 46 cases and comprehensive literature review.

INTRODUCTION: Malignant pericardial effusion is a severe complication of lung and breast cancer. The median survival is less than 4 months and recurrences occurs in about 40% of cases. Systemic chemotherapy and/or local treatments are necessary, even if there is no consensus. METHODS: We collected data from patients in our center from 1997 to 2016 who received at least one intrapericardial instillation of bleomycin (60mg). At the same time, we conducted a review of the relevant literature on the subject. RESULTS: We included 46 patients in the analysis. Median survival was 2.6 months [95% CI: 1.7; 4.7]. Overall survival was 49% [33%; 63%] at 3 months and 28% [15%; 42%] at 6 months. In the lung cancer subgroup, overall survival was 18% [3%; 44%] at 3 months. In the breast cancer subgroup, overall survival was 73% [44%; 89%] at 3 months and 46% [21%; 69%] at 6 months. DISCUSSION: The best response rates in the literature are obtained with local instillation of bleomycin or cisplatin. Malignant pericardial effusions in breast cancer patients had a better prognosis. This is certainly related to the prognosis of the underlying disease. We have not found an increase in overall survival with intrapericardial chemotherapy injections, but preventing recurrence of malignant pericardial effusions is a benefit in itself, thus avoiding a lethal complication.

Mid-Term Efficacy of Subxiphoid Versus Transpleural Pericardial Window for Pericardial Effusion.

BACKGROUND: The optimal surgical technique for drainage of pericardial effusions is frequently debated. Transpleural drainage via thoracotomy or thoracoscopy is hypothesized to provide more durable freedom from recurrent pericardial effusion than a subxiphoid pericardial window. We sought to compare operative outcomes and mid-term freedom from recurrent effusion between both approaches in patients with nontraumatic pericardial effusions. METHODS: All patients at our institution who underwent a pericardial window from 2001 to 2018 were identified. After excluding those who underwent recent cardiothoracic surgery or trauma, patients (n = 46) were stratified by surgical approach and presence of malignancy. Primary outcome was freedom from recurrent moderate or greater pericardial effusion. Secondary outcomes included operative mortality and morbidity and mid-term survival. Follow-up was determined by medical record review, with a follow-up of 67 patient-years. Fisher's exact test and Wilcoxon rank-sum test were used to compare groups. Mid-term survival and freedom from effusion recurrence were determined using Kaplan-Meier method. RESULTS: Subxiphoid windows (n = 31; 67%) were more frequently performed than transpleural windows (n = 15; 33%) and baseline characteristics were similar. Effusion etiologies included malignancy (n = 22; 48%), idiopathic (n = 12; 26%), uremia (n = 8; 17%), and collagen vascular disease (n = 4; 9%). Perioperative outcomes were comparable between the two surgical approaches, except for longer drain duration (7 versus 4 d, P = 0.029) in the subxiphoid group. Operative mortality was 19.6% overall and 36.4% in patients with malignancy. Mid-term survival and freedom from moderate or greater pericardial effusion recurrence was 37% (95% confidence interval [CI]: 19%-54%) and 69% (95% CI: 52%-86%) at 5 y, respectively. There was no difference in mid-term survival (P = 0.90) or freedom from pericardial effusion recurrence (P = 0.70) between surgical approaches. Although malignant etiology had worse late survival (P < 0.01), freedom from effusion recurrence was similar to nonmalignant etiology (P = 0.70). CONCLUSIONS: Pericardial window provides effective mid-term relief of pericardial effusion. Subxiphoid and transpleural windows are equivalent in mid-term efficacy and both surgical approaches can be considered. Patients with malignancy have acceptable operative mortality with low incidence of recurrent effusion, supporting palliative indications.

Hemopericardium Following Transseptal Puncture During Balloon Mitral Valvotomy: Management Strategies and Outcomes.

BACKGROUND: Hemopericardium is a major complication of balloon mitral valvotomy (BMV). Only a few studies are available to address this issue following transseptal access. In addition, the management strategy regarding completion of BMV is uncertain. OBJECTIVE: We sought to determine the incidence of hemopericardium complicating transseptal puncture during BMV. In addition, the management strategy adopted and outcomes are highlighted. METHODS: This prospective study included 29 consecutive patients who developed hemopericardium following transseptal access during BMV. RESULTS: Out of 1424 patients who underwent BMV, hemopericardium developed in 29 patients following transseptal access (2.0%). The mean age of the study cohort was 36.9 ± 13.7 years and 82.8% were women. A second transseptal puncture was done and BMV was completed in 26 patients (89.6%). An acceptable hemodynamic result was obtained in 22 patients (84.6%). Six patients (20.7%) underwent emergency surgery for hemopericardium. The sites of perforation were inferior vena cava-right atrial junction in 4 cases, left atrial posterior wall in 1 case, and left atrial appendage in 1 case. In addition to repair of the perforation, a total of 2 patients underwent mitral valve replacement and 1 patient underwent open mitral commissurotomy. The in-hospital mortality rate was 6.9%. CONCLUSIONS: The incidence of hemopericardium complicating transseptal access during BMV was 2.0%, and was associated with a mortality rate of 6.9%. BMV can be safely performed in the same sitting with a second transseptal puncture, in patients with a favorable valve morphology. Surgical intervention can be reserved for a subset of patients with persistent pericardial collection.

Prognostic factors and nomogram for cancer-specific death in non small cell lung cancer with malignant pericardial effusion.

BACKGROUND: The prognosis of lung cancer with malignant pericardial effusion is very terrible owing to the impact of cardiac tamponade. The aim of our study seeks to identify prognostic factors and establish a prognostic nomogram of non small cell lung cancer (NSCLC) with malignant pericardial effusion. METHODS: NSCLC patients with malignant pericardial effusion between 2010 and 2014 are searched from SEER database.Cancer-specific death of these patients are analyzed through the Kaplan-Meier method, Cox proportional hazard model and competing risk model. Prognostic nomogram of cancer-specific death is performed and validated with concordance index (C-index), calibration plots and internal validation population. Propensity score matching is used to evaluate whether chemotherapy affected the survival of study population. RESULTS: 696 eligible NSCLC patients are involved in the study population, with 22.7% of 1-year survival rate and 8.9% of 2-year survival rate. Laterality, AJCC N, AJCC T, and chemotherapy are regarded as independent prognostic factors of cancer-specific death in the Cox proportional hazards model and competing risk model. The C-index of established nomogram is 0.703(95%CI:0.68-0.73) for cancer-specific death in the study population with acceptable calibration, which is significantly higher than classical TNM stage(C-index = 0.56, 95%CI:0.52-0.60). After 1:1 propensity score matching, chemotherapy potentially reduces the risk of cancer-specific death (HR = 0.42 95%CI: 0.31-0.58) of NSCLC with pericardial effusion. CONCLUSIONS: NSCLC with malignant pericardial effusion harbors low overall survival. One prognostic nomogram based on laterality, AJCC N, AJCC T and chemotherapy is developed for cancer-specific death to predict 1-year and 2-year survival rate with good performance.

Pericardial effusion in prosthetic and native valve infective endocarditis.

BACKGROUND: Pericardial effusion (PE) is widely believed to signify more advanced infective endocarditis (IE) and a generally worse outcome. PURPOSE: To determine the prevalence and clinical significance of PE in a series of patients with confirmed native and prosthetic valve infections. METHODS: Data were collected from 338 consecutive patients with definite or possible IE who visited a single referral center; these patients were examined for the presence of PE as detected by transthoracic echocardiography. Clinical characteristics, the incidence of complications, and outcomes were compared between patients with IE with and without PE. IE patients with PE were then divided into two subgroups: those with and those without cardiac prostheses. RESULTS: Eighty-eight patients out of the total 338 (26%) were found to have PE. Compared with patients who did not have PE, patients who did were significantly younger (32.9 ± 13.4 vs 29.0 ± 9.2, p = 0.003), had more left-sided vegetation (55.6% vs 77.3%, p < 0.001), more root abscesses (9.2% vs 25.0%, p < 0.001), needed surgery more frequently (68.0% vs 84.1%, p = 0.001), and had a higher mortality rate (22.0% vs 32.9%, p = 0.03). PE was not found to be a predictor of mortality. No significant difference was found between IE patients with PE with (n = 13) and without (n = 75) prostheses with regard to causative organisms, clinical characteristics, or clinical outcomes. CONCLUSION: Regardless of whether the IE was in native or prosthetic valves, compared with patients without PE, patients with PE had more severe infections and a worse prognosis, but PE was not an independent predictor of mortality.

Rationale and Design of a Phase II Trial of Osimertinib Combined With Bevacizumab in Patients With Untreated Epidermal Growth Factor Receptor-mutated Non-small-cell Lung Cancer and Malignant Pleural and/or Pericardial Effusion (SPIRAL II Study).

Progression-free survival (PFS) of patients with non-small-cell lung cancer with pleural or pericardial effusion is expected to be prolonged with combination use of an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor plus bevacizumab compared with that with an EGFR-tyrosine kinase inhibitor alone. Phase I clinical trial data have been reported for combined treatment with osimertinib plus bevacizumab and demonstrated their safety, but the efficacy remains unclear, particularly in patients with pleural or pericardial effusion. This is an ongoing single arm, prospective, open-label, multicenter, phase II trial to evaluate the efficacy and safety of osimertinib plus bevacizumab combination therapy in EGFR mutation-positive patients with untreated or recurrent non-small-cell lung cancer and pleural and/or pericardial effusion. Osimertinib will be administered orally once daily at a dose of 80 mg. One cycle consists of 21 days. Bevacizumab 15 mg/kg will be administered by drip infusion on Day 1 of each cycle. Treatment will be continued until progressive disease or any of the discontinuation criteria are met. The primary endpoint will be the 1-year PFS rate. Secondary endpoints are response rate, PFS, overall survival, survival not requiring pleural/pericardial drainage, and safety. Osimertinib plus bevacizumab combination therapy is expected to prolong PFS and reduce adverse events. TRIAL REGISTRATION NUMBER: UMIN000028071.

Effect of pericardial effusion on outcomes in children admitted with systemic lupus erythematosus: a multicenter retrospective cohort study from the United States.

OBJECTIVE: We sought to describe characteristics of children admitted with pericardial effusion (PCE) and systemic lupus erythematosus (SLE) and determine the association between PCE and outcomes of interest. METHODS: We performed a retrospective cohort study of the Pediatric Health Information System (PHIS). Patients were included if they were admitted to a PHIS participating hospital from 2004 to 2015 with a diagnosis of SLE and age ≤18 years. Children with congenital heart disease or who had undergone heart surgery were excluded. PCE was the primary predictor variable; multivariable analysis was used to evaluate the effect of PCE on the following outcomes: mortality, length of stay (LOS), and readmission within 30 days. RESULTS: There were 5679 admissions, of which 705 (12.4%) had PCE. Median age at admission was 15 years (interquartile range: 13-17). There were no significant differences for age or sex between patients admitted either with or without PCE. A significantly higher percentage of children in the PCE group were black compared with those without PCE (43% vs. 31%, p < 0.001). In multivariable analysis, the odds of a black patient having PCE were 1.7 higher than non-black patients ( p < 0.001). In-hospital mortality was 2.5 times higher in children with PCE compared with those without PCE ( p = 0.027). Those with PCE also had 1.5 greater odds of readmission within 30 days ( p < 0.001). PCE was not associated with increased LOS (0.99, p = 0.753). CONCLUSION: PCE is common in admissions of children with SLE. There are disproportionately more black patients with SLE affected by PCE than non-black. PCE is associated with significantly higher mortality and rates of readmission.

Is pericardial effusion a negative prognostic marker? Meta-analysis of outcomes of pericardial effusion.

BACKGROUND: The prognostic relevance and the prevalence of pericardial effusion in several diseases are not well established. The aim of this meta-analysis is to summarize the available evidence related to pericardial effusion prevalence and outcomes according to the cause. METHODS: Articles investigating the prognosis of pericardial effusion were identified by literature search. Twenty-three studies were finally included (17 022 patients). All-cause mortality was the primary end-point. Secondary end-point was the prevalence of pericardial effusion in most common diseases related to this clinical condition. RESULTS: The pooled prevalence of pericardial effusion was 19.5% [95% confidence interval (CI): 14.3-26]. After a mean follow-up of 36 ±â€Š23 months, the risk of death was higher in pericardial effusion patients [hazard ratio (HR) 1.59, 95% CI 1.37-1.85, P < 0.0001]. Stratifying for the main disease, pericardial effusion is associated with unfavourable outcome in all available subgroups: pulmonary arterial hypertension HR 1.53 (95% CI: 1.22-1.92; P < 0.0001), chronic heart failure (CHF) HR 1.53 (95% CI: 1.22-1.92; P < 0.0001), myocardial infarction HR 2.65 (95% CI: 1.4-4.99; P = 0.003) and malignancies HR 1.75 (95% CI: 1.09-2.81, P = 0.021). The lack of data concerning the idiopathic pericardial effusion does not permit a secure risk assessment but the average incidence of mortality is 14.5% (95% CI: 7.7-25.6). CONCLUSION: Pericardial effusion should be considered a marker of the severity of the underlying disease, whereas for idiopathic pericardial effusion the correlation with poor prognosis is less clear.

Doses of radiation to the pericardium, instead of heart, are significant for survival in patients with non-small cell lung cancer.

BACKGROUND AND PURPOSE: Higher cardiac dose was associated with worse overall survival in the RTOG0617 study. Pericardial effusion (PCE) is a common cardiac complication of thoracic radiation therapy (RT). We investigated whether doses of radiation to the heart and pericardium are associated with PCE and overall survival in patients treated with thoracic radiation for non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: A total of 94 patients with medically inoperable/unresectable NSCLC treated with definitive RT in prospective studies were reviewed for this secondary analysis. Heart and pericardium were contoured consistently according to the RTOG1106 Atlas, with the great vessels and thymus of the upper mediastinal structures included in the upper part of pericardium, only heart chambers included in the heart structure. Clinical factors and dose-volume parameters associated with PCE or survival were identified via Cox proportional hazards modeling. The risk of PCE and death were mapped using DVH atlases. RESULTS: Median follow-up for surviving patients was 58 months. The overall rate of PCE was 40.4%. On multivariable analysis, dosimetric factors of heart and pericardium were significantly associated with the risk of PCE. Pericardial V30 and V55 were significantly correlated with overall survival, but presence of PCE and heart dosimetric factors were not. CONCLUSION: PCE was associated with both heart and pericardial doses. The significance of pericardial dosimetric parameters, but not heart chamber parameters, on survival suggests the potential significance of radiation damage to the cranial region of pericardium.

Risk factors of pericardial effusion in native valve infective endocarditis and its influence on outcome: A multicenter prospective cohort study.

BACKGROUND: Pericardial effusion is a frequent finding in the setting of infective endocarditis. Limited data exists on clinical characteristics and outcomes in this group of patients. We aimed to determine the associated factors, clinical characteristics, and outcomes of patients who had pericardial effusion and native valve infective endocarditis. METHODS AND RESULTS: A total of 1205 episodes of infective endocarditis from 25 Spanish centers between June 2007 and March 2013 within the Spanish Collaboration on Endocarditis (GAMES) registry were included. Echocardiogram at admission, clinical and microbiological variables, and one-year follow-up were analyzed. Pericardial effusion was observed in 7.8% (94/1205 episodes) of episodes of infective endocarditis, most of them being mild or moderate (93.6%). The presence of pericardial effusion was associated with a higher risk of heart failure during admission (OR 1.9; CI 95% 1.2-3.0). Patients with pericardial effusion had a higher rate of surgery (53.2% vs. 41.1%; p = 0.02); however, this association was no longer significant after adjusting for possible confounders (OR 1.4; CI 95% 0.9-2.2; p = 0.10). The presence of pericardial effusion was not associated with a higher in-hospital or one-year mortality (33.0% vs. 25.2%; p = 0.10 and 40.2% vs. 37.3%; p = 0.60 respectively). CONCLUSIONS: The prevalence of pericardial effusion in patients with infective endocarditis was lower than previously reported. The presence of pericardial effusion is associated with the development of heart failure during hospitalization making it a warning sign, possibly reflecting indirectly a mechanical complication, which, however, if treated surgically in a timely manner does not change the final outcome of patients.

Incidence and Management of Hemopericardium: Impact of Changing Trends in Invasive Cardiology.

OBJECTIVE: As invasive cardiovascular care has become increasingly complex, cardiac perforation leading to hemopericardium is a progressively prevalent complication. We sought to assess the frequency, etiology, and outcomes of hemorrhagic pericardial effusions managed through a nonsurgical echo-guided percutaneous strategy. PATIENTS AND METHODS: Over a 10-year period (January 1, 2007, to December 31, 2016), 1097 unique patients required pericardiocentesis for clinically important pericardial effusions. Of these 411 had drainage of hemorrhagic effusions (defined as a pericardial hemoglobin level >50% of serum hemoglobin or frank blood in the setting of cardiac perforation). Clinical characteristics, echocardiographic data, details of the procedure, and outcomes were determined. RESULTS: Median patient age was 67 years (interquartile range, 56-76 years), and 60% were men. The procedure was emergent in 83% and elective in 17%. The site of pericardiocentesis was determined by echo-guidance in all: 68% from the left para-apical region, 18% from the left or right parasternal areas, and 14% were subxyphoid. Half (n=215 [52%]) occurred after cardiac perforation with percutaneous interventional procedure (ablation, n=94; device lead implantation, n=65; percutaneous coronary intervention, n=22; other, n=34), whereas 30% followed cardiac or thoracic surgery. Pericardial fluid volume drained was 546±440 mL. In 94% of cases, echo-guided pericardiocentesis was the only treatment of the effusion needed, whereas definitive surgery was required in 25 (6%) cases for persistent bleeding or acute management of the underlying etiology. There was no procedural mortality. Late mortality was better for hemorrhagic effusions compared with a contemporary cohort with nonhemorrhagic effusions. CONCLUSION: Echocardiographic guidance allows rapid successful pericardiocentesis in the setting of hemopericardium related to microperforation with interventional procedures, malignancy, or pericarditis, with most not requiring surgical intervention. Surgery should remain the first-line approach for aortic dissection or myocardial rupture.

Safety and Outcome of Percutaneous Drainage of Pericardial Effusions in Patients with Cancer.

Malignancy is a common cause of pericardial effusions. The findings, immediate safety and longer-term outcomes of pericardiocentesis are less well defined. We reviewed the cases of all patients with malignancy that underwent pericardiocentesis at our institution over a 10-year period. From January 1, 2007 to December 31, 2016, 171 patients with cancer underwent echo-guided pericardiocentesis. A total of 53% were male with a mean age of 60 ± 15 years. The average volume drained was 485 (IQR 350 to 719) ml. The procedure was technically successful in 170/171 (99.4%) of patients without significant complications; there were no procedure-related deaths. A total of 20% had hemorrhagic, 48% had serosanguinous, and 31% serous pericardial effusions. The type of effusion was not associated with outcome. Cytology (measured in 164) was positive in 58% and only weakly related to outcome (median survival nine versus 18 weeks, p = 0.04). Per our institutional practice, a pericardial catheter was left in place until there were less than 50 ml of net drainage in 24 hours (average 3 ± 2 days). A total of 135 patients had metastatic carcinoma, 23 patients had lymphoma or chronic leukemia and 4 metastatic sarcoma. Patients with either lymphoma or chronic leukemia had better survival than those with carcinoma or sarcoma (median survival 102 vs 12 weeks, p < 0.0001) with a 46% vs 3% 5-year survival, p < 0.0001). Echoguided pericardiocentesis with extended pericardial catheter placement is safe and effective in cancer patients with pericardial effusions. However, overall outcomes are poor in cancer patients with pericardial effusions that required drainage, particularly in those with carcinoma or sarcoma.

Pericardial windows have limited diagnostic success.

BACKGROUND: Pericardial effusion (PE) is a common finding in patients who have chronic cardiac failure, who had undergone cardiac surgery, or who have certain other benign and malignant diseases. Pericardial drainage procedures are often requested for both diagnostic and therapeutic purposes. The perceived benefit is that it allows for diagnosis of malignancy or infection for patients with PEs of unclear etiology. The purpose of the study is to determine the diagnostic yield of surgical drainage procedures. METHODS: We conducted a retrospective chart review of patients who underwent surgical drainage procedures of PEs from July 1st, 2011 to January 1st, 2017 at a single institution. The variables included data on preoperative, intraoperative, and postoperative findings; morbidity; and survival. RESULTS: A total of 145 patients with an average age of 61 ± 5 and primarily men (53%) were evaluated. All of the surgical drainage procedures were performed through the sub-xiphoid approach. Twenty-five of the 145 patients (17.2%) had diagnostic findings in either the pericardial tissue or fluid. The cytology alone was diagnostic in 4.8% (N = 7) of patients with mixed findings including adenocarcinoma of the lung and breast. The pathology was diagnostic for cancer in 1.4% (N = 2) of patients with Melanoma and Lung cancer identified. The cytology and pathology were concordant in 4.0% (N = 6) identifying cancers that included mesothelioma and adenocarcinoma. Infection was identified in the pericardial fluid in 6.9% (N = 10) of the patients. CONCLUSION: Surgical pericardial drainage procedures allow for removal of PE that may lead to tamponade physiology and potential mortality. Although there is therapeutic benefit from these procedures there is only a small diagnostic benefit.

Echocardiographic characteristics of primary malignant pericardial mesothelioma and outcomes analysis: a retrospective study.

BACKGROUND: Little is known about the echocardiographic characteristics of primary malignant pericardial mesothelioma (PPM) due to its rarity. The aim of this study was to explore the sex-specific echocardiographic patterns of PPM and risk factors for in-hospital mortality. METHODS: A retrospective information retrieval was conducted for cases of PPM reported from China during 1981 and 2015. The diagnosis was made by histopathological examinations and only cases with echocardiographic descriptions were included. Data on the clinical and echocardiographic findings were collected. Difference in clinical, sex-specific echocardiographic characteristics and findings across different time periods were assessed. Logistic regression analysis was performed to explore echocardiographic risk factors for in-hospital mortality. RESULTS: A total of 64 patients with PPM were included, with a mean age of 39.2 ± 15.6 years and minor male dominance (40, 62.5%). The most common echocardiographic presentations were pericardial effusion (55, 85.9%), pericardial masses (36.4%) and thickening (17.3%), respectively. The positive rate of pericardiocentesis was only 20.9%. Six patients (15.4%) died among 39 cases reporting in-hospital outcome. Logistics analysis identified no clinical or echocardiographic parameters associated with in-hospital mortality (all P > 0.05). CONCLUSIONS: The echocardiographic signs of PPM are basically nonspecific with massive pericardial effusion as the most common sign, although no echocardiographic gender differences or association with in-hospital mortality could be identified.

Incidence, Prevention, and Management of Periprocedural Complications of Left Atrial Appendage Occlusion.

Major procedural complications related to left atrial appendage occlusion (LAAO) are relatively infrequent but may be associated with major morbidity and mortality. LAAO operators should be knowledgeable about these potential complications. Prompt recognition and treatment are necessary to avoid rapid deterioration and dire consequences. With stringent guidelines on operator training, competency requirements, and procedural-technical refinements, LAAO can be performed safely with low complication rates. This article focuses on commonly used devices, as well as prevention, treatment, and management of complications of LAOO.

Pericardial effusion unrelated to surgery is a predictor of mortality in heart transplant patients.

BACKGROUND: Hemodynamically irrelevant pericardial effusion (PeEf) is a predictor of adverse outcome in heart failure patients. The clinical relevance of a PeEf unrelated to surgery in heart transplant patients remains unknown. This study assesses the prognostic value of PeEf occurring later than 1 year after transplantation. METHODS: All patients undergoing heart transplantation in Zurich between 1989 and 2012 were screened. Cox proportional hazard models were used to analyze mortality (primary) and hospitalization (secondary endpoint). PeEf time points were compared to baseline for rejection, immunosuppressants, tumors, inflam-mation, heart failure, kidney function, hemodynamic, and echocardiographic parameters. RESULTS: Of 152 patients (mean age 48.3 ± 11.9), 25 developed PeEf. Median follow-up period was 11.9 (IQR 5.8-17) years. The number of deaths was 6 in the PeEf group and 46 in the non-PeEf group. The occurrence of PeEf was associated with a 2.5-fold increased risk of death (HR 2.49, 95% CI 1.02-6.13, p = 0.046) and hospitalization (HR 2.53, 95% CI 1.57-4.1, p = 0.0002). CONCLUSIONS: This study reveals that the finding of hemodynamically irrelevant PeEf in heart trans-plant patients is a predictor of adverse outcome, suggesting that a careful clinical assessment is war-ranted in heart transplant patients exhibiting small PeEf.
