RÉSUMÉ

Large pericardial effusions with associated cardiac tamponade are a rare manifestation of hypothyroidism. We present the case of a 63-year-old female with chronic heart failure and newly diagnosed hypothyroidism, who presented to her primary care physician complaining of progressively worsening dyspnea. Chest radiography showed cardiomegaly and transthoracic echocardiography (TTE) revealed a large pericardial effusion with tamponade physiology. An emergent pericardial window was performed, resulting in an improvement in left ventricular systolic function. Pericardial tissue biopsy was normal. Thyroid function tests were consistent with severe primary hypothyroidism. After inpatient treatment with intravenous levothyroxine and interval resolution of symptoms without recurrence of effusion, the patient was discharged home on oral levothyroxine therapy. Close follow up with surveillance echocardiography was planned. While metabolic disorders are seldom thought of as an etiology, it is imperative for clinicians to recognize hypothyroidism as a cause of the pericardial effusion. It is one of the few reversible causes and delay in treatment can result in fatal sequelae.

RÉSUMÉ

We report two rare cases of cardiac tamponade after left upper lobectomy. Case 1:A 76-year-old man underwent thoracoscopic left upper lobectomy and lymph node dissection for lung cancer. The patient suddenly developed cardiac tamponade the day after surgery. Emergency surgery was performed to stop bleeding and confirm the source of bleeding, and dark red pericardial fluid and hematoma were observed in the pericardial sac. There was no postoperative recurrence of cardiac tamponade. He died 1 year and 2 months after the operation. Case 2:A 77-year-old woman underwent thoracoscopic left upper lobectomy and lymph node dissection for lung cancer. The patient did well until the 6th postoperative day. On the 7th postoperative day, she complained of sudden severe back pain, immediately after which she lost consciousness and went into cardiopulmonary arrest. The echocardiography revealed cardiac tamponade, and emergency pericardiocentesis was performed. The patient died without circulatory improvement despite drainage of approximately 200 ml of bloody pericardial fluid. The pathological findings of autopsy revealed penetrating atherosclerotic ulcer at the descending aorta. We speculated that severe back pain caused the afterload of left ventricle and the increase in left atrial pressure through mitral regurgitation, which might result in a bleeding from the staple-line of superior pulmonary vein in the pericardium.

RÉSUMÉ

Acute Myeloid Leukemia (AML) is a life-threatening illness that requires prompt diagnosis and often immediate treatment. It can present in a variety of manners but most commonly is associated with fevers, fatigue, shortness of breath, or infection. Extramedullary leukemia is a less common finding upon initial presentation, but includes dermatologic manifestations, including leukemia cutis, and rarely, large mass-like presentations known as myeloid sarcomas. While leukemic infiltration of organ systems is a well-described phenomenon, cardiac tamponade is a rare form of presentation. Herein we describe a 58-year-old man with a recent hospitalization for idiopathic cardiac tamponade who re-presented to the hospital with worsening dyspnea and fevers. He was found to have a recurrent pericardial effusion with features concerning for tamponade, as well as worsening thrombocytopenia and macrocytic anemia. Bone marrow biopsy revealed 24% myeloblasts, confirming the diagnosis of AML. Notably, his cardiac symptoms improved with treatment of his leukemia. To our knowledge, this is one of only a few cases of AML with cardiac tamponade as the initial presentation.

RÉSUMÉ

Point-of-care ultrasound (POCUS) has been shown to be a valuable tool in the management of acutely ill patients in the prehospital setting. POCUS not only has utility from a diagnostic perspective but also has been shown to reduce the rate of complications from otherwise traditionally "blind" procedures, such as pericardiocentesis. This case report highlights the utility of POCUS in the prehospital setting to guide emergent pericardiocentesis to treat cardiac tamponade. The applicability of various approaches to ultrasound-guided pericardiocentesis is also discussed.

RÉSUMÉ

BACKGROUND: Thymic mucosa-associated lymphoid tissue (MALT) lymphoma is rare and is known to be associated with Sjögren's syndrome (SjS). SjS is rarely accompanied by serositis. Here, we describe the first case of postoperative cardiac tamponade and acute pleuritis in a patient with thymic MALT lymphoma associated with SjS. CASE PRESENTATION: A 33-year-old woman with SjS presented with an anterior mediastinal mass on chest computed tomography, which was performed for further examination of the condition. Suspecting a thymic MALT lymphoma or thymic epithelial tumor, total thymectomy was performed. The mediastinal mass was histopathologically diagnosed as a thymic MALT lymphoma. The patient was discharged with a good postoperative course but visited the hospital 30 days after surgery for dyspnea. Cardiac tamponade was observed and drainage was performed. Four days after pericardial drainage, chest radiography revealed massive left pleural effusion, and thoracic drainage was performed. The patient was diagnosed with serositis associated with SjS and treated with methylprednisolone, which relieved cardiac tamponade and pleuritis. CONCLUSIONS: Surgical invasion of thymic MALT lymphomas associated with SjS may cause serositis. Postoperative follow-up should be conducted, considering the possibility of cardiac tamponade or acute pleuritis due to serositis as postoperative complications.

RÉSUMÉ

INTRODUCTION: Purulent pericarditis secondary to esophago-pericardial fistula is a serious complication that has been previously reported in patients with esophageal cancer treated with radio/chemotherapy and esophageal stenting. However, the presence of esophago-pericardial fistula as the first manifestation of advanced carcinoma of the esophagus is exceedingly infrequent. We report the case of a 61-year-old male who presented with sepsis, cardiac tamponade and septic shock who was found to have an esophago-pericardial fistula secondary to squamous carcinoma of the esophagus. Emergency pericardiocentesis was performed with subsequent hemodynamic improvement. The drained pericardial fluid was purulent in nature and cultures were positive for Streptococcus anginosus. A CT scan followed by upper gastrointestinal endoscopy with tissue biopsy confirmed the diagnosis of squamous cell carcinoma of the esophagus. A self-expanding covered stent was endoscopically placed to exclude the fistula and restore the esophageal lumen. In this report, we discuss some aspects related to the diagnosis and management of this serious clinical entity.

RÉSUMÉ

RATIONALE: Recombinant human endostatin (Endostar) is extensively utilized in China for the clinical management of patients with driver gene-negative non-small cell lung cancer (NSCLC) at stage TNM IV. This report describes the case of a lung cancer patient treated exclusively with Endostar maintenance therapy, who experienced a rapid deterioration in respiratory function. PATIENT CONCERNS: The case involved a patient with a pathologically confirmed squamous cell carcinoma of the left lung, treated in our department. Following 1 month of albumin-bound paclitaxel chemotherapy and localized radiotherapy for the left lung lesion, the patient initiated treatment with a single agent, Endostar 30mg, on October 19, 2021. The medication was administered via intravenous infusion over a 7 days. DIAGNOSIS: On October 23, 2021, the patient exhibited symptoms of chest constriction, discomfort, coughing, and sputum production. By October 28, the patient presented with pronounced dyspnea and respiratory distress. An emergency CT scan detected pericardial tamponade and significant deviations in several blood parameters from pretreatment values. INTERVENTIONS: Percardial puncture and catheter drainage were recommended as therapeutic intervention. OUTCOMES: Considering the patient advanced age, the patient and their family opted to refuse this medical procedure, leading to the patient unfortunate demise on November 2, 2021. LESSONS: Medical professionals should remain vigilant for the potential, albeit rare, risk of Endostar inducing acute pericardial tamponade, a severe and potentially fatal complication.

RÉSUMÉ

Cardiopulmonary resuscitation (CPR) is essential for the survival of cardiac arrest patients, but it can cause severe traumatic complications. In the catheterization laboratory, various physical constraints complicate the appropriate performance of CPR. However, we are not aware of reports of CPR complications in this setting. Here, we report a case of coronary artery perforation (CAP) caused by manual CPR in the catheterization laboratory. The patient, a 68-year-old woman, initially underwent successful percutaneous coronary intervention (PCI) for unstable angina. Back in the ward, the patient experienced acute stent thrombosis, which resulted in cardiac arrest, and another PCI was performed under ongoing manual CPR. Although revascularization was successful, sudden CAP occurred, leading to cardiac tamponade. Despite extensive treatment efforts, the patient died 18 hours later.Initially, the compression site of CPR was on the midline of the sternum; however, the compression site shifted to the left, to just above the left anterior descending artery, by the time that CAP was detected via angiography. This corresponded to the area where rib fractures were observed upon computed tomography, suggesting the possibility of traumatic CAP due to manual CPR. The physical constraints in the catheterization laboratory can lead to an inappropriate CPR technique and severe traumatic complications.

RÉSUMÉ

In patients with cardiac amyloidosis, pericardial involvement is common, with up to half of patients presenting with pericardial effusions. The pathophysiological mechanisms of pericardial pathology in cardiac amyloidosis include chronic elevations in right-sided filling pressures, myocardial and pericardial inflammation due to cytotoxic effects of amyloid deposits, and renal involvement with subsequent uremia and hypoalbuminemia. The pericardial effusions are typically small; however, several cases of life-threatening cardiac tamponade with hemorrhagic effusions have been described as a presenting clinical scenario. Constrictive pericarditis can also occur due to amyloidosis and its identification presents a clinical challenge in patients with cardiac amyloidosis who concurrently manifest signs of restrictive cardiomyopathy. Multimodality imaging, including echocardiography, cardiac computed tomography, and cardiac magnetic resonance imaging, is useful in the evaluation and management of this patient population. The recognition of pericardial effusion is important in the risk stratification of patients with cardiac amyloidosis as its presence confers a poor prognosis. However, specific treatment aimed at the effusions themselves is seldom indicated. Cardiac tamponade and constrictive pericarditis may necessitate pericardiocentesis and pericardiectomy, respectively.

RÉSUMÉ

Fetal pericardial teratomas are rare. They present with pericardial effusion and hydrops. The definitive management is postnatal resection of the tumor. The exact antenatal management is not known due to its rarity. We present a case of fetal pericardial teratoma with pericardial tamponade. Pericardiocentesis performed at 31 weeks significantly relieved the venous compression, leading to resolution of hydrops and prolonging the gestational age for the definitive management.

RÉSUMÉ

A 55-year-old male with acute pericarditis presented with low-pressure cardiac tamponade (LPCT) unresponsive to volume infusion. Subsequent pericardiocentesis resulted in hemodynamic improvement and unmasking of pericardial constriction. This case provides illustrative hemodynamic tracings of LPCT. Additionally, the presence of concurrent pericardial constriction that may indicate a plausible underlying mechanism for the blunted responsiveness to fluid expansion in LPCT. The underlying physiologic processes and the associated hemodynamic tracings are discussed.

RÉSUMÉ

BACKGROUND: Post-Operative Atrial Fibrillation (POAF) is the most frequent complication of cardiac surgery and is associated with reduced survival, increased rates of cognitive changes and cerebrovascular accidents, heart failure, renal dysfunction, infection, length of stay and hospital costs. Cardiac tamponade although less common, carries high morbidity and mortality. Shed mediastinal blood in the pericardial space is a major source of intrapericardial oxidative stress and inflammation that triggers POAF. The utilisation of a posterior pericardiotomy (PP) aims to shunt blood from pericardium into the pleural space and have a role in the prevention of POAF as well as cardiac tamponade. METHODS: 2168 patients had undergone isolated Coronary Artery Bypass Grafting at Royal Hobart Hospital from 2008 to 2022. They were divided into PP group vs. control group. Patient baseline demographics, intraoperative data and post-operative outcomes were reviewed retrospectively. RESULTS: Total incidence of new POAF and cardiac tamponade was 24% and 0.74% respectively. Primary outcome of both the incidence of POAF (20.2% vs. 26.3%, p < 0.05) and Cardiac Tamponade (0% vs. 1.1%, p < 0.05) were less in the pericardiotomy group. A subgroup analysis of patients with recent myocardial infarction showed reduced incidence of POAF in the PP group (p < 0.05). Increasing age, Body Mass Index, poor left ventricular ejection fraction (EF < 30%) and return to theatre were independent predictors of developing POAF. There were similar rates of return to theatre for bleeding however, no cases of tamponade in the pericardiotomy group. There were no complications attributable to left posterior pericardiotomy and the time added to the duration of surgery was minimal. CONCLUSION: Posterior pericardiotomy is associated with a significant reduction in the incidence of POAF and cardiac tamponade which is safe and efficient.

RÉSUMÉ

Pericardiocentesis is an important diagnostic and therapeutic procedure. In the setting of cardiac tamponade, pericardiocentesis can rapidly improve hemodynamics, and in cases of diagnostic uncertainty, pericardiocentesis allows for fluid analysis to aid in diagnosis. In contemporary practice, the widespread availability of ultrasonography has made echocardiographic guidance the standard of care. Additional tools such as micropuncture technique, live ultrasonographic guidance, and adjunctive tools including fluoroscopy continue to advance and enhance procedural efficiency and safety. When performed by experienced operators, pericardiocentesis is a safe, effective, and potentially life-saving procedure.

RÉSUMÉ

BACKGROUND: There is insufficient information regarding the bleeding sites and surgical strategies of cardiac tamponade during catheter ablation for atrial fibrillation (AF). CASE PRESENTATION: Of the five patients with cardiac tamponade, three required surgical intervention and two required pericardiocentesis. In the first case of three cardiac tamponades requiring surgical intervention, considering that the peripheral route was used, the catecholamines did not reach the heart, and due to unstable vital signs, venoarterial extracorporeal membrane oxygenation (VA-ECMO) was inserted. No bleeding point was identified, but a thrombus had spread around the left atrium (LA) with diverticulum. Hemostasis was achieved with adhesives placed around the LA under on-pump beating. In the second case, pericardiocentesis was performed, but the patient showed heavy bleeding and unstable vital signs. Thus, VA-ECMO was inserted. Heavy bleeding was expected, and safety was enhanced by attaching a reservoir to the VA-ECMO. The bleeding point was found between the left upper pulmonary artery and LA under cardiac arrest to obtain a good surgical view for suturing repair. In the third case, the LA diverticulum was damaged. Pericardiocentesis resulted in stable vitals, but sustained bleeding was present. A bleeding point was found at the LA diverticulum, and suture repair under on-pump beating was performed. CONCLUSIONS: When cardiac tamponade occured in any patient with LA diverticulum, treatment could not be completed with pericardiocentesis alone, and thoracotomy was likely to be necessary. If the bleeding point could be confirmed, suturing technique is a more reliable surgical strategy than adhesive alone that leads to pseudoaneurysm. If the bleeding point is unclear, it is important to confirm the occurrence of LA diverticulum using a preoperative CT, and if confirmed, cover it with adhesive due to a high possibility of diverticulum bleeding. The necessity of CPB should be determined based on whether these operations can be completed while maintaining vital stability.

RÉSUMÉ

The aim of this study was to assess the usefulness of postmortem contrast-enhanced CT (PMeCT) performed via direct large-vessel puncture when routine postmortem CT suggests a vascular lesion as the cause of death. PMeCT was performed in 9 cases (4 male, 5 female) with a mean age of 76 years (range 52-92) at the time of death. The mean time elapsed since death was 29.1 h (12.0-72.0). The location of the target vessel for puncture was determined based on the CT table position and a grid placed on the body surface. An 18-G spinal needle was advanced to the puncture site, and the needle tip was confirmed to have reached the intended blood vessel. Using negative pressure with a 20-ml syringe, the needle tip was advanced until reverse bleeding was confirmed. Diluted contrast medium was injected slowly to ensure its dispersion within the blood vessels. Following confirmation of no extravasation, additional doses of diluted contrast agent were injected in 3-4 divided doses, with CT scans obtained at each step to track the distribution of contrast agent over time. PMeCT was successful in all cases, revealing cardiac tamponade in 7 (ascending aortic dissection, n = 6; cardiac rupture, n = 1), thoracic aortic aneurysm rupture, n = 1, and iliac artery aneurysm rupture, n = 1. There were no cases of procedure-related extravasation (pseudo-lesions). When postmortem CT reveals pericardial hematoma or bleeding in the thoracic or abdominal cavity, PMeCT can identify the source of bleeding.

RÉSUMÉ

BACKGROUND: Iatrogenic complications of endovascular treatment for central venous stenosis have not yet been reported. Here we present a case of a patient on maintenance hemodialysis who developed catheter-related superior vena cava syndrome and subsequently suffered from hemorrhagic pericardial tamponade after undergoing percutaneous transluminal angioplasty and stenting. CASE PRESENTATION: A 72-year-old male patient presented with uremia, and had been receiving maintenance hemodialysis for the past five years. The patient initially presented with dysfunction of the dialysis catheter (a cuffed tunneled double-lumen catheter in the right internal jugular vein). Imaging examination revealed a segmental occlusion of the superior vena cava stretching from the distal end of the dialysis catheter up to right atrium entrance, apparent compensatory dilatation of the azygos vein, and abundant subcutaneous collaterals. The patient underwent percutaneous transluminal balloon dilatation and stenting (covered stent) of the superior vena cava in the Cath Lab. During the procedure, with forceful advancement of the guidewire, it was observed to progress for a distance before a "smoke" appeared, and an outward spillage of contrast agent was visible, which suggested a possible vessel puncture leading into the mediastinum. Unfortunately, postoperative hemorrhagic pericardial tamponade occurred and the patient developed cardiogenic shock. He experienced symptoms included chest tightness and breath shortness with a recorded blood pressure of 84/60mmHg. After draining 600 ml of bloody fluid through pericardiocentesis, the patient's symptoms alleviated and his condition improved. CONCLUSIONS: The case emphasizes the need for increased attention to iatrogenic endovascular injuries during catheter placement and endovascular treatment, such as causing pericardial hemorrhage leading to cardiac tamponade.
