Rare cardiac metastasis of lung cancer mimicking aneurysm and tamponade.

Metastasis of non-small cell lung carcinoma (NSCLC) is a rare cause of cardiac metastatic tumors (CMT). We present a case of NSCLC infiltrating the apical left ventricle mimicking cardiac aneurysm and tamponade. The patient, who had a history of NSCLC, presented with acute shortness of breath and an echocardiogram concerning for ruptured left ventricular aneurysm. A neoplastic mass found at the cardiac apex suggested CMT leading to ventricular wall rupture and cardiac tamponade. Transthoracic echocardiography is the most ubiquitous imaging modality for CMT diagnosis, with cardiac magnetic resonance imaging offering a more detailed assessment. CMT from NSCLC can cause dangerous cardiac tamponade, warranting consideration in patients with suspected metastases.

Metastasis of non­small cell lung carcinoma (NSCLC) to the heart is uncommon but can lead to serious complications including life-threatening cardiac tamponade.Diagnosis of cardiac metastatic tumors from NSCLC often involves echocardiography, but cardiac magnetic resonance imaging provides additional insights in cases where echocardiography results are inconclusive.

An Unusual Cause of Shock: Bursting a Bubble.

This study presents the case of a previously healthy 68-year-old woman who presented with shock from tamponade due to hemopericardium. Initial noninvasive imaging did not provide a clear etiology for the hemopericardium. Given the ongoing clinical deterioration and need for diagnosis and treatment, an exploratory sternotomy was performed with successful outcome.

Hantavirus-Induced Cardiac Tamponade: A Diagnostic Dilemma.

Herein we describe a case of a 60-year-old white male from New York City who was admitted to hospital due to worsening dyspnea. He presented with an acute onset of fever, night sweats, and progressively worsening non-productive cough and orthopnea over the preceding week. Electrocardiogram findings revealed atrial fibrillation. Manifesting signs of hypoperfusion, a trans-esophageal echocardiography was performed, which demonstrated the presence of a cardiac tamponade. An emergency pericardiocentesis was performed, draining 750 cc of serosanguinous content. Laboratory investigations depicted an inflammatory milieu marked by lymphocytic leukocytosis, cardiac function impairment, and remarkably elevated d-dimer and brain natriuretic peptide levels. Notably, high-sensitivity troponin T remained within normal limits. Comprehensive viral panel assays, including COVID-19, Influenza A+B, Respiratory Syncytial Virus, Hepatitis C, HIV, Cytomegalovirus, Coxsackie A+B, and Herpes Simplex Virus, returned negative results. Furthermore, anti-nuclear factor and rheumatoid factor titers were negative. Blood and fungal cultures, as well as assessments for Mycobacterium tuberculosis, yielded negative findings. On further history-taking, he reported that he had occupational exposure to rat droppings and urine two weeks ago. Serological analysis demonstrated positive hantavirus IgG and IgM antibodies. Supportive management was initiated. Consequently, the patient was discharged asymptomatic, without pericardial effusion. Evaluation after two weeks revealed no recurrence of symptoms.

In the Catheterization Laboratory, Most Iatrogenic Cardiac Tamponades Require Only Pericardiocentesis: A Single-Center Experience.

Background: Cardiac tamponade (CT) is a rare but life-threatening complication of cardiac interventions, requiring immediate pericardial cavity pressure relief. While pericardiocentesis often suffices, and some cases necessitate open-chest surgery. This decision is frequently based on individual physician's experience. This study aims to identify high-risk CT patients following cardiac intervention, advocating for early, decisive surgical intervention. Methods: A retrospective analysis was conducted on 51 patients who developed iatrogenic CT at our center between October 2013 and October 2023. Patients were classified based on the necessity for open-chest surgery. The study evaluated a variety of factors, including baseline characteristics, therapeutic approaches, and outcomes. Results: Of the 51 patients with iatrogenic CT, 49 patients were successfully treated without open-chest surgery, with an average immediate drainage volume of 208.2 ± 173.8 mL. In contrast, the two patients requiring open-chest surgery had significantly higher drainage volumes, exceeding 500 mL, with over 300 mL drained in the first hour, indicating laceration injuries. Patients not requiring open-chest surgery demonstrated favorable outcomes. Conclusions: The majority of patients with iatrogenic CT and non-lacerated injuries experienced a favorable prognosis following pericardiocentesis. However, in cases of lacerated injuries with drainage volume was above 300 mL per hour, pericardiocentesis alone could not stabilize the hemodynamics due to persistent bleeding. Immediate surgery may be needed in these cases.

Survival predictor in emergency resuscitative thoracotomy for blunt trauma patients: Insights from a Chinese trauma center.

PURPOSE: Emergency resuscitative thoracotomy (ERT) is a final salvage procedure for critically injured trauma patients. Given its low success rate and ambiguous indications, its use in blunt trauma scenarios remains highly debated. Consequently, our study seeks to ascertain the overall survival rate of ERT in blunt trauma patients and determine which patients would benefit most from this procedure. METHODS: A retrospective case-control study was conducted for this research. Blunt trauma patients who underwent ERT between January 2020 and December 2023 in our trauma center were selected for analysis, with the endpoint outcome being in-hospital survival, divided into survival and non-survival groups. Inter-group comparisons were conducted using Chi-square and Fisher's exact tests, the Kruskal-Wallis test, Student's t-test, or the Mann-Whitney U test. Univariate and multivariate logistic regression analyses were conducted to assess potential predictors of survival. Then, the efficacy of the predictors was assessed through sensitivity and specificity analysis. RESULTS: A total of 33 patients were included in the study, with 4 survivors (12.12%). Multivariate logistic regression analysis indicated a significant association between cardiac tamponade and survival, with an adjusted odds ratio of 33.4 (95% CI: 1.31 - 850, p = 0.034). Additionally, an analysis of sensitivity and specificity, targeting cardiac tamponade as an indicator for survivor identification, showed a sensitivity rate of 75.0% and a specificity rate of 96.6%. CONCLUSION: The survival rate among blunt trauma patients undergoing ERT exceeds traditional expectations, suggesting that select individuals with blunt trauma can significantly benefit from the procedure. Notably, those presenting with cardiac tamponade are identified as the subgroup most likely to derive substantial benefits from ERT.

Glue-Assisted Retinopexy for Retinal Detachments Study Report 2: Fibrin Glue As a Surgical Adjunct in Complex Rhegmatogenous Retinal Detachment.

Purpose: To present the successful application of fibrin glue as a surgical adjunct in the management of complex rhegmatogenous retinal detachment (RRD). Methods: In this retrospective case series, fibrin glue was used as a surgical adjunct in 5 cases of complex RRD. In each case, standard pars plana vitrectomy and laser retinopexy were performed by the same surgeon. Fibrin glue was used intraoperatively as a tamponade to seal the breaks because the isolated use of conventional tamponade agents was not feasible given the variable nature of the complex RRDs, the anatomy of the eye, or an inability to maintain postoperative positioning. Results: In 1 patient previously treated for a large corneoscleral tear, fibrin glue was used to seal a large iatrogenic retinal break caused by a fragmatome-related surge that led to a quadrantic RD. In 2 patients treated for combined RRD, fibrin glue was used with silicone oil to manage recurrent RRD with incompletely drained thick subretinal fluid and blood. In 2 other cases, fibrin glue was applied to manage RRD in congenital aniridia with advanced glaucoma and aphakia. In all cases, retinal attachment without serious adverse effects was attained over a follow-up ranging from 4 to 6 months. Conclusions: Fibrin glue is an effective, safe surgical adjunct in complex RRD. It can be used to transiently seal a retinal break when use of a conventional tamponade agent is not possible or not sufficient alone.

Trends and outcomes of inpatient cardiac implantable electronic device transvenous lead extractions: a nationwide analysis.

BACKGROUND: Higher rates of CIED implantations have been associated with an increased rate of lead failures and complications resulting in higher rates of transvenous lead extractions (TLE). OBJECTIVE: To assess the trends TLE admissions and evaluate the patient related predictors of safety outcomes. METHODS: National Readmission Database was queried to identify patients who underwent TLE from January 2016 to December 2019. We conducted a multivariate regression analysis to identify variables associated with in-hospital mortality in patients undergoing TLE. Additionally, we compared trends and outcomes of TLE among patients with prior sternotomy versus those without prior sternotomy and analyzed sex-based differences among patients undergoing TLE. RESULTS: We identified 30,128 hospitalizations for TLE. The index admission in-hospital mortality rate was 3.21% with cardiac tamponade happening in 1.46% of the admissions. Age, infective endocarditis, CKD, congestive heart failure and anemia were associated with higher in-hospital mortality rates. There was a lower rate of in-hospital mortality in patients with history of prior sternotomy versus patients without (OR 0.72, CI: 0.59-0.87, p-value < 0.001). There was no difference in in-hospital mortality rate between males and females. Females had a shorter length and a higher cost of stay when compared to male gender. CONCLUSION: TLE admissions continue to increase. Overall rates of mortality and complications are relatively low. Patients with prior sternotomy had better outcomes and less complications when compared to those without prior sternotomy. Female gender is associated with higher rates of cardiac tamponade, yet shorter length of stay with lower cost.

Current practice of ultrasound in the management of postpartum hemorrhage: a secondary analysis of a national survey.

OBJECTIVES: Although frequently employed in the delivery room, current guidelines do not recommend the use of ultrasound in the setting of postpartum hemorrhage (PPH). The aim of this survey was to evaluate the routine use of ultrasonography during PPH. METHODS: A questionnaire, composed by a series of questions that assess participant characteristics and ultrasound use during PPH, was sent to members of the Italian Society of Ultrasound in Obstetrics and Gynecology currently employed in obstetrical units. Answers were subsequently grouped based on participant characteristics. RESULTS: Based on the responses of 200 participants it was found that ultrasound was routinely employed by 67 % of participants during PPH, by 85 % if Retained Products of Conception (RPOC) was suspected, by 67 % during Bakri balloon placement and by 69 % during curettage procedures. Routine ultrasound use was higher amongst participants working in hospitals with a higher number of deliveries, by those with more years of experience using ultrasound in labor, and by those that had attended specific postgraduate training courses. CONCLUSIONS: Despite the lack of recommendations in the current guidelines, the results of this survey show that ultrasound seems to be commonly employed by maternal fetal medicine practitioners in the management of PPH.

Cardiac Tamponade as a Harbinger of Hypothyroidism.

Cardiac tamponade is a rare complication of hypothyroidism. In rarer cases, hypothyroidism may initially present with tamponade. Cardiac tamponade is an emergency condition that usually requires urgent intervention. However, guidelines for tamponade secondary to hypothyroidism are not optimal, and cases have been managed variably (ranging from levothyroxine alone to pericardiocentesis followed by thyroid hormone replacement) with diverse outcomes. Here, we report a case of a 42-year-old male with no medical history who presented with exertional dyspnea, lower leg swelling, facial puffiness, constipation, and weight gain. He had low blood pressure (80/60 mm Hg), normal heart rate with sinus rhythm, normal oxygen saturation, and was afebrile. Apart from a mildly raised creatinine, his test results were normal. An echocardiogram revealed features of tamponade. Further laboratory tests showed severe hypothyroidism. Following the initiation of levothyroxine, he demonstrated significant improvement. Coronary angiography revealed 95% stenosis in the mid-left anterior descending artery, treated with stenting. Serial echocardiograms showed regression of the pericardial effusion, stabilizing his condition without the need for invasive pericardiocentesis. This case highlights the importance of prompt diagnosis and management of hypothyroidism-related tamponade to prevent severe cardiac compromise. Hence, it may be necessary to consider hypothyroidism in the differential for patients with unexplained cardiac tamponade.

Acute procedural safety of the latest radiofrequency ablation catheters in atrial fibrillation ablation: Data from a large prospective ablation registry.

BACKGROUND: Safety data of the latest radiofrequency (RF) technologies during atrial fibrillation (AF) ablation in real-world clinical practice are limited. OBJECTIVES: We sought to evaluate the acute procedural safety of the four latest ablation catheters commonly used for AF ablation. METHODS: A total of 3957 AF ablation procedures performed between January 2022 and December 2023 at 20 centers with either the THERMOCOOL SMARTTOUCH SF (STSF), TactiCath (TC), QDOT Micro (QDM), or TactiFlex (TF) were retrospectively analyzed. RESULTS: In total, QDM, STSF, TF, and TC were used in 343 (8.7%), 1793 (45.3%), 1121 (28.4%), and 700(17.7%) procedures. Among 2406 index procedures, electrical pulmonary vein isolations were successfully achieved in 99.5%. Despite similar total procedure times in the four groups, the total fluoroscopic time was significantly shorter for QDM/STSF with CARTO than TF/TC with EnSite (18.7 ± 14 vs. 27.6 ± 20.6 min, p < .001) and longest in the TF group. The incidence of cardiac tamponade was 0.7% (0.5% and 0.9% during index and redo procedures, 0.8% and 0.3% for paroxysmal and non-paroxysmal AF) and was significantly lower for QDM/STSF than TF/TC (0.2% vs. 1.1%, p = .008) and highest in the TF group. The incidence of cardiac tamponade was higher for TF than TC and STSF than QDM. In the multivariate analysis, TF/TC with EnSite was a significant independent predictor of cardiac tamponade during both the index (odds ratio [OR] = 4.8, 95% confidence interval [CI] = 1.3-17.5, p = .02) and all procedures (OR = 3.0, 95% CI = 1.3-7.2, p = .01). CONCLUSIONS: The incidence of cardiac tamponade and the fluoroscopic time during AF ablation significantly differed among the latest RF catheters and mapping systems in real-world clinical practice.

Lung Adenocarcinoma Presenting as Early Cardiac Tamponade: A Case Report.

Introduction: Lung cancer remains the most common cause of cancer death in the USA and worldwide despite continued advances in lung cancer screening and treatment. Pericardial effusion (PerF) has been found in up to 50% of postmortem patients with cancer; lung and breast cancers are the most frequent malignancies. Furthermore, it is a sign of poor outcomes with fewer than 5 months of survival. Nevertheless, PErF with or without tamponade as a presentation of lung cancer is uncommon. Case Presentation: We present a 72-year-old male without medical history who presented with 1 month of cough with white sputum and shortness of breath, progressively worsening, associated with weight loss (20 pounds). Further studies demonstrated early cardiac tamponade secondary to malignancy. Conclusion: Cardiac tamponade can arise secondarily from various etiologies and have different presentations depending on the cause. In general, it is a slowly developing and clinically silent disease process. Therefore, malignant PerFs can rarely present with hemodynamic instability and be the initial manifestation of an underlying malignancy. Our case review presents a rare case of metastatic lung adenocarcinoma manifesting as early symptomatic cardiac tamponade and as an emergency. The results might be life-threatening if this presentation is not recognized and managed appropriately. Clinicians must be aware of such atypical presentations of thoracic malignancies to take action adequately.

Concomitance of Pericardial Tamponade and Pulmonary Embolism in an Invasive Mucinous Lung Adenocarcinoma with Atypical Presentation: Diagnostic and Therapeutic Pitfalls-Case Report and Literature Review.

The invasive mucinous adenocarcinoma of the lungs (LIMA) is an uncommon histological subtype of the mucinous adenocarcinoma. In this article, we present the case of a patient with a very high cardiovascular risk profile, diagnosed with LIMA, pericardial tamponade due to secondary dissemination, and pulmonary embolism, whose management rouses many challenges. Despite receiving the correct anticoagulant and antiaggregant therapy, our patient developed repeated acute major cardiovascular events leading to a fatal outcome. To gather additional information on LIMA and the above cluster of pathologies, we performed the first research of the international medical literature for scientific articles published in the last eight years on PubMed, ResearchGate, Clarivate, and Google Scholar. As the first literature research failed to identify any case similar to our patient, we performed a second study of the same databases for subjects with lung adenocarcinoma instead of LIMA and the same comorbidities, and we found 10 cases. LIMA is a less frequent type of adenocarcinoma, with polymorphic radiologic appearances on the chest computed tomography, frequently mimicking pneumonia, and thus delaying the diagnosis and therapy. It has a worse prognosis and higher mortality than the common adenocarcinoma, but information on its secondary dissemination and complications is still required.

Percutaneous pericardiocentesis using the apical approach: case series and review of the literature.

BACKGROUND: Pericardiocentesis offers a definitive diagnostic and a life-saving therapeutic modality through removal of pericardial fluid and relief of high intrapericardial pressure. Percutaneous pericardiocentesis has been performed via different approaches depending on different institutional experiences. In this paper, we present our institutional experience and review the current literature of the different approaches for performing percutaneous pericardiocentesis. MATERIALS AND METHODS: We evaluated consecutive patients who underwent echocardiographic-guided pericardiocentesis via the apical approach for pericardial effusion between the period of April 1st, 2022, and April 1st, 2023, at University of Arkansas for Medical Sciences (UAMS). Health records were reviewed for clinical presentations, available imaging findings, procedural outcomes, and short-term follow up. RESULTS: A total of eight consecutive cases of pericardiocentesis via the apical approach were found. Seven were successful. No complications were reported. Six patients had evidence of tamponade physiology on echocardiogram. CONCLUSION: Historically, pericardiocentesis has been most performed via the subxiphoid approach. However, an ultrasound-guided apical approach offers a safe and effective alternative and may be preferable in patients with challenging anatomies.

Rapid Development of Primary Right Atrial Angiosarcoma.

Cardiac angiosarcomas are rare and generally followed by a high level of metastasis with poor median survival outcomes. Echocardiograms, CT scans, and MRIs are the standard methods for finding sites of cardiac tumors; however, immunohistochemical confirmation is necessary for a definitive diagnosis of angiosarcoma. A 58-year-old male presented to the emergency room with one week of dyspnea on moderate exertion accompanied by chest pain and alleviated with rest. A workup done to evaluate mass found a single 5 x 3.5 x 4.8 cm mass heavily vascularized by the right coronary artery and left circumflex involving the free wall of the right atrium with no extension to the tricuspid valve. Surgical resection was performed, and immunohistochemistry was consistent with a primary cardiac angiosarcoma. An exudative fluid analysis on pericardial and pleural fluid analysis may warrant screening for malignancy more frequently in concurrence with a patient's history and presentation. Although the time from onset of symptoms to diagnosis of cardiac angiosarcoma is not well established, further investigation of such correlation may offer insight into survival post-treatment.

Pericardial Decompression Syndrome: A Comprehensive Review of a Controversial Entity.

Pericardial decompression syndrome is an ambiguous clinical entity which has generated controversy regarding its existence. Following pericardial decompression, patients experienced clinical deterioration ranging in complications from pulmonary edema to death that could not be attributed to any other distinct clinical pathology. Multiple theories have suggested the pathophysiology behind pericardial decompression syndrome is related to preload-afterload mismatch following pericardial decompression, coronary microvascular ischemia, and stress from high adrenergic state. Our review aims to describe this syndrome by analyzing demographics, etiology of pericardial effusion, method of drainage, volume of pericardial fluid removed, time to decompensation, and clinical outcomes. A systematic review of MEDLINE/PubMed and Google Scholar literature databases were queried for case reports, case series, review articles, and abstracts published in English journals between 1983 and December 2022. Each author's interpretation of echocardiographic and/or pulmonary arterial catheterization data provided in the case reports was used to characterize ventricular dysfunction. Based on our inclusion criteria, 72 cases of pericardial decompression syndrome were included in our review. Our results showed that phenotypic heterogeneity was present based on echocardiographic findings of right/left or biventricular failure with similar proportions in each type of ventricular dysfunction. Time to decompensation was similar between immediate, subacute, and acute cases with presentation varying between hypoxic respiratory failure and shock. This review article highlights theories behind the pathophysiology, clinical outcomes, and therapeutic options in this high mortality condition.

Innovative hemostasis technique for cesarean section in placenta previa: A retrospective study.

OBJECTIVE: To evaluate hemostatic efficacy, complications, and subsequent pregnancy outcomes in women with placenta previa who underwent combined vertical compression sutures in the lower uterine segment and intrauterine balloon tamponade (Hot-Dog method) to achieve hemostasis after cesarean section. METHODS: We retrospectively reviewed data for 117 women with singleton pregnancy diagnosed with placenta previa who underwent cesarean section between 29 and 38 weeks' gestation. Treatments were as follows: (1) conventional-intravenous oxytocin administration after placental detachment and suturing of bleeding points at the detachment site as needed (conventional group) (n = 47). (2) Intrauterine balloon tamponade alone (balloon group) (n = 41). (3) Vertical compression sutures + intrauterine balloon tamponade (Hot-Dog group) (n = 29). RESULTS: The placenta accreta spectrum prevalence was significantly higher in the balloon and Hot-Dog groups versus the conventional group. The prevalence of anteriorly located placenta was significantly higher in the Hot-Dog versus balloon groups. Intraoperative and total blood loss were significantly higher in the Hot-Dog versus conventional groups. Postoperative blood loss was significantly lower in the Hot-Dog versus balloon groups. Fewer additional procedures for managing postoperative hemorrhage were required in the Hot-Dog versus conventional and balloon groups. The number of subsequent pregnancies in the conventional, balloon, and Hot-Dog groups was 11 (23.4%), 8 (19.5%), and 4 (13.8%), respectively; all resulted in live births at term without serious obstetric complications. CONCLUSION: The Hot-Dog method is a straightforward and safe hemostasis technique for placenta previa that preserves fertility and controls severe bleeding.

Aortic Dissection Complicated by Coronary Malperfusion and Tamponade: A Case Report.

Aortic dissection is rare and often presents with atypical symptoms. We describe a case of a patient with acute aortic dissection involving the coronary arteries, complicated by pericardial tamponade, and discuss findings using point-of-care ultrasound, diagnostics, and treatment of this condition.
