Cardiac tamponade is caused by an abnormal increase in fluid accumulation in the pericardial sac, which, by raising intracardiac pressures, impedes normal cardiac filling and reduces cardiac output, sometimes dramatically so. This article outlines the pathophysiology, clinical features, and treatment of this important clinical condition highlighting the important role played by echocardiography in diagnosis and management.

REVIEW
Amir Azarbal, Martin M LeWinter
The normal pericardial sac contains up to 50 mL of fluid, which consists of a plasma ultrafiltrate. Anything greater constitutes a pathologic effusion. The curvilinear pressure-volume relationship of the pericardial sac dictates hemodynamic consequences of a pericardial effusion and is responsible for rapidly accumulating fluid that causes cardiac tamponade. A variety of diseases and complications cause pericardial effusion. The most common are idiopathic pericarditis, cancer, connective tissue disorders, and hemorrhage...

Bo Xu, Deborah H Kwon, Allan L Klein
Pericardial diseases represent diverse conditions, ranging from painful inflammatory states, such as acute pericarditis, to life-threatening tamponade and chronic heart failure due to constrictive pericarditis. Multimodality cardiovascular imaging plays important roles in diagnosis and management of pericardial conditions. This review provides a clinical update on multimodality cardiovascular imaging of the pericardium, incorporating echocardiography, multidetector computed tomography, and cardiac magnetic resonance imaging, focusing on guiding clinicians about when each cardiac imaging modality should be used in each relevant pericardial condition...

REVIEW
Ralph Shabetai, Jae K Oh
Constrictive pericarditis and cardiac tamponade cause severe diastolic dysfunction, but do not depress systolic function until the agonal state has been reached. Multimodality cardiovascular imaging has brought the nuances of pericardial disease to the domain of the practicing cardiologist. This introduction is a revised article originally written by the late Dr Shabetai for a pericardial diseases textbook which was not published. He was the editor of previous Pericardial Diseases issue for Cardiology Clinics in the 1980s, it is most appropriate to begin our issue with his insights...

OBJECTIVE: To determine if concentrations of plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) are increased in dogs with cardiac tamponade and if there is a significant increase in plasma NT-proBNP after pericardiocentesis. ANIMALS: Ten client-owned dogs with spontaneous cardiac tamponade. METHODS: Prospective clinical study. Cardiac tamponade was suspected from physical examination and confirmed with echocardiography. Blood was collected and plasma NT-proBNP concentrations were measured before and 30-60 min following pericardiocentesis and resolution of cardiac tamponade...

While cardiac involvement is not a common presentation in human echinococcosis, it may lead to life-threatening complications including cyst rupture; anaphylactic shock; tamponade; pulmonary, cerebral or peripheral arterial embolism; acute coronary syndrome; dysrhythmias; infection; ventricular or valvular dysfunction, as well as sudden death. Here we report a 9-year old girl who was diagnosed to have hydatid cyst of the interventricular septum four years after diagnosis and medical treatment of pulmonary hydatidosis...

We report a case of a patient presenting with abdominal pain after cardiac surgery who was noted on point-of-care ultrasound (POCUS) to have pericardial and pleural effusion, in addition to ascites. The most notable findings were pleural and pericardial effusions, which combined with symptomatology met criteria for postpericardiotomy syndrome. Point-of-care ultrasound expedited the diagnosis of a pericardial effusion with impending tamponade and transfer for pericardiocentesis and placement of pericardial drain...

REVIEW
Yogen Singh
Hemodynamic instability and inadequate cardiac performance are common in critically ill children. The clinical assessment of hemodynamic status is reliant upon physical examination supported by the clinical signs such as heart rate, blood pressure, capillary refill time, and measurement of the urine output and serum lactate. Unfortunately, all of these parameters are surrogate markers of cardiovascular well-being and they provide limited direct information regarding the adequacy of blood flow and tissue perfusion...

We describe an unusual presentation of Merkel cell carcinoma (MCC), a rare neuroendocrine cutaneous tumour. A 59-year-old man presented with a 2-week history of dyspnoea on a background of MCC of the left elbow that was diagnosed after an axillary lymph node metastasis had appeared. He was clinically diagnosed with cardiac tamponade and received urgent pericardiocentesis. Thoracic CT imaging revealed a large infiltrating mass within the inferior aspect of the heart, confirmed to be MCC via immunohistochemistry of the pericardial fluid...

Pneumopericardium is an overall rare condition caused by increased intrathoracic positive pressure. Different mechanisms can contribute to its development. It can be observed in both pediatric and adult populations. Only a small percentage of patients have cardiac tamponade. We describe the first case of delayed tension pneumopericardium after elective lobectomy. Sudden symptom onset and clinical management are discussed. Only an accurate and quick patient assessment allowed diagnosing this condition and, hence, its correct treatment...

BACKGROUND: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) may be life-saving in several clinical situations, but it is also one of the most invasive therapeutic procedures, with significant potential for life-threatening complications. Pulse pressure waves are typically very small or even absent at the onset of ECMO therapy, and will reappear with the improvement of cardiac function. A low pulse pressure may indicate low cardiac output due to heart failure during sustained ECMO support...

INTRODUCTION: Non-occlusive mesenteric ischemia (NOMI) develops without anatomical causes. Early diagnosis is challenging and treatments are of questionable effectiveness. We investigated the role of complement activation in the pathophysiology of NOMI in animal models through the inhibition of complement C5a. MATERIALS AND METHODS: 60-min partial aortic occlusion (PAO; abdominal aorta, proximal to celiac trunk; mean arterial pressure: 30-40 mmHg) was established in Sprague-Dawley rats (n = 28) and 60-min cardiac tamponade in minipigs (n = 19; mean arterial pressure: 40-50 mmHg) to observe short- and long-term circulatory and inflammatory consequences of NOMI...

INTRODUCTION: Transesophageal echocardiography (TEE) is a well-established method of evaluating cardiac pathology. It has many advantages over transthoracic echocardiography (TTE), including the ability to image the heart during active cardiopulmonary resuscitation. This prospective simulation study aims to evaluate the ability of emergency medicine (EM) residents to learn TEE image acquisition techniques and demonstrate those techniques to identify common pathologic causes of cardiac arrest...

Left atrial appendage (LAA) exclusion is performed by some surgeons in patients with atrial fibrillation (AF) who undergo coronary artery bypass grafting (CABG). However, the available evidence regarding the efficacy and safety of this procedure remains mixed. We queried the Nationwide Inpatient Survey Database for the 10-year period from 2004 to 2013. Using International Classification of Diseases, Ninth Edition, Clinical Modification diagnosis codes, we identified patients who had a diagnosis of AF and underwent a primary procedure of CABG with or without LAA exclusion...

Congenital diverticula of the left ventricle, very rare malformations, are determined by an abnormal embryonic development of the ventricular wall and can be isolated or associated to other cardiac anomalies. In most of the cases, these pathologies are not symptomatic and in some patients can be associated to ventricular arrhythmia, cardiac rupture with tamponade and sudden death. Authors are presenting the case of a sudden death in an 8-weeks-old newborn due to rupture of a cardiac congenital diverticulum of the left ventricle, discovered only at the moment of the autopsic examination...

Penetrating thoracic injuries are rare in Germany and common in urban regions. 10 percent of the patients in Emergency Departments suffer from blunt thoracic trauma. Mechanism of trauma can predict the severity of the injuries. Very fast life-threatening injuries with hemodynamic problems like tension pneumothorax or cardiac tamponade have to be diagnosed. Prehospital emergency physicians need skills in ultrasound for diagnosis and in invasive therapy like chest tube or pericardium drainage tube. The application of an algorithm in exploration of a thoracic trauma seems to be useful...
