The characteristics of cardiac tamponade in patients with human immunodeficiency virus (HIV) disease were examined by evaluating the cases, case series, and related articles, including autopsy series, identified through a comprehensive literature search. One-hundred eighty-five cases of cardiac tamponade have been reported in patients with HIV disease. Sex data were available in 176 patients, of whom 154 (87%) were males. The mean age was 34.7 +/- 10.4 years (range, 11 months to 61 years). Mean CD4 cell count was 98 +/- 95 cells/mm3 (range, 3 to 430 cells/mm3). The most common etiology of pericardial tamponade was mycobacterial infection (78 patients), including Mycobacterium tuberculosis, Mycobacterium avium-intracellulare, and Mycobacterium kansasii. A bacterial cause was found in 20 patients (11%). Staphylococcus aureus was the predominant bacteria, followed by streptococci, Pseudomonas aeruginosa, Listeria monocytogenes, Klebsiella pneumoniae, and Rhodococcus equi. Lymphoma was found in 15 (8%) patients and Kaposi sarcoma in 13 (7%) patients. Numerous unusual organisms, including Cryptococcus neoformans, Nocardia asteroides, Aspergillus species, cytomegalovirus, and herpes simplex were also associated with cardiac tamponade in HIV patients. Occasionally, HIV itself was involved in the pathogenesis. In 48 patients (26%), no cause was found or reported. The most common clinical presentation was dyspnea, followed by fever, cough, chest pain, and cardiac arrest. The predominant pericardial fluid color composition was serosanguineous. The majority of patients died during hospitalization or in the immediate follow-up period. Vigilance for cardiac tamponade in patients with HIV disease, especially in those with opportunistic infections and/or malignancies, and cardiac symptoms, may result in early and proper management of cardiac tamponade in these patients.

A 6-year-old 18-kg (39-lb) spayed female Standard Poodle was referred for treatment of pneumopericardium. The dog did not have severe clinical signs relating to the pneumopericardium, and the diagnosis was made incidentally while investigating the cause of a cough. Computed tomography revealed an air-filled structure consistent with a bulla to the right of the heart base that appeared to communicate with the pericardial cavity Because spontaneous resolution of the pneumopericardium seemed unlikely and cardiac tamponade was a possibility, exploratory thoracotomy was performed. A lobulated bulla was found at the hilus of the right middle lung lobe adhered to the underlying pericardial sac, and a 4-cm-diameter communication from the pericardium to the pulmonary bulla was found. Right middle lung lobectomy was performed, and the pericardiotomy and pericardial opening were sutured. The dog recovered without complications. In previously reported cases of pneumopericardium involving a cat and a dog, the condition resolved spontaneously. In this dog, in contrast, surgical resection of the affected lung lobe with pericardial reconstruction was required for resolution of the pneumopericardium.

A 1-year-5-months-old female who had cough, rhinorrhea and prolonged fever for 19 days was admitted to the intensive care unit due to exertional dyspnea. She was intubated promptly in virtue of hypotension and cyanosis. The physical examination demonstrated diminished breathing sound over the right lung and distant heart sound; echocardiogram showed cardiac tamponade. Further X ray study showed right hydropneumothorax and cardiomegaly. Pericardiocentesis and chest thoracostomy were performed, and subsequently all the cultures showed growth of Streptococcus pneumoniae. Antibiotics therapy was started promptly after admission. Further investigation indicated osteomyelitis of the right ilium, so that surgical debridement was done. The patient was discharged 54 days later with complete recovery. After following up for 18 months, no restrictive heart disease developed. Purulent pericarditis with cardiac tamponade is an extremely rare complication of pneumococcal infection.

Breast cancer rarely metastasizes to the pericardial cavity to cause cardiac tamponade. We have recently experienced a case of pericardial tamponade due to recurrent breast cancer. A 41-year-old woman who underwent modified radical mastectomy for a right breast cancer (T(1)N(3)M(0), Stage IIIA) 8 years and 8 months ago, was admitted for dyspnea and cough. Chest X-ray and CT scan revealed cardiomegaly and right pleural effusion, and cardiac echogram showed marked retention of pericardial effusion. A diagnosis of cardiac tamponade was made, and pericardiocentesis and thoracentesis were carried out immediately. Based on cytodiagnosis of pericardial and pleural effusion, the diagnosis was pericardial and intrapleural metastases of the breast cancer. Dyspnea was improved by pericardiocentesis and thocacentesis. Both intrapericardiac and intrathoracic instillation of CDDP prevented reaccumulation of pericardial and pleural effusion. After local chemotherapy with CDDP, systemic chemotherapy of CPT-11 was started. Thereafter the patient was discharged from the hospital and recovered her daily activities. This case indicates that intrapericardiac application of CDDP was effective for carcinomatous cardiac tamponade without serious side effects.

The patient was a 40-year-old woman who was admitted to our hospital because of severe cough and dyspnea due to multiple lung metastases from breast cancer, who had undergone Auchincloss operation for right breast cancer about five years earlier. While systemic chemotherapy (CAF) was started after admission,she presented with cardiac tamponade. A cardiac echogram revealed marked retention of pericardial effusion. Pericardiocentesis was carried out, and the cytology of the effusion showed class V, resulting in the diagnosis of carcinomatous cardiac tamponade due to breast cancer. She was treated with intrapericardial chemotherapy using OK-432 and mitomycin C (MMC), and has not suffered from pericardial effusion after the intrapericardial chemotherapy. Intrapericardial chemotherapy using OK-432 and MMC may be very useful for malignant pericardial effusion.

It remains unclear whether advances in the understanding of the pathophysiology and improvements in cardiovascular imaging over the years have impacted the clinician's recognition of cardiac tamponade (CT). We sought to evaluate signs and symptoms of CT in a present-day population and compare it to a similar group from a decade prior. We performed a retrospective analysis of two cohorts of patients presenting to a tertiary hospital with CT, all of whom underwent pericardial drainage (PD). Group 1 (Gp1) included subjects presenting from 1988 to 1991 and Group 2 (Gp2) included subjects from 2002 to 2005. Fifty-five patients comprised each group, with an average age of 55 years. Seventy-one percent of patients in Gp1 had identifiable cardiovascular symptoms 1 week prior to presentation, compared to 33% in Gp2. Dyspnea was the most common symptom in both groups, and was less frequent in Gp2. Compared with Gp1, chest pain, cough, and lethargy were also less frequent in Gp2. One day prior to PD, tachypnea and pulsus paradoxus were detected more frequently in Gp1 compared to Gp2. Large, circumferential pericardial effusions were the most frequent echocardiographic findings in both groups and the most common etiology of CT was malignancy in Gp1and postoperative bleeding in Gp2. Thus, the recognition of symptoms and physical signs in patients presenting with CT has changed over the past decade, as has etiology of pericardial effusions. However, the diagnosis of CT still remains delayed, and the present data emphasize the need for a heightened index of suspicion for recognizing this hemodynamically-important process.

Pericarditis as a presenting sign of infective endocarditis is rare. Here we describe 2 cases and an additional 19 cases of pericarditis as a presenting sign of infective endocarditis reported during the last 40 y. 71% of patients were young males (mean age 43.2 y). The most commonly reported underlying conditions were diabetes mellitus type 2 (5 patients, 24%), and substance or alcohol abuse (4 patients, 19%). The native aortic valve was the most frequently involved valve. The most common symptoms were fever, cough or dyspnoea, and chest pain. Overt tamponade was diagnosed in 47% of the patients. However, pulsus paradoxus and pericardial friction rub were rare. A heart murmur was heard in 12 patients (57%). Staphylococcus aureus was the most commonly isolated pathogen concomitantly from blood and pericardial fluid. 16 patients (76%) were operated. Six underwent a pericardial procedure, 5 underwent valve replacement, 4 both, and 1 patient was operated for pseudoaneurysm. Mortality rates were 60% and 31% of patients treated with antibiotics alone versus antibiotics and surgical intervention, respectively. In patients presenting with pericarditis with or without cardiac tamponade, the possibility of infective endocarditis should be considered. Optimal therapy should consist of antibiotics and surgical intervention.

Tuberculosis accounts for up to 4% of acute pericarditis and 7% cases of cardiac tamponade. Prompt treatment can be life saving but requires accurate diagnosis. We report a case of 30-year-old male who presented with fever, chills, and dry nonproductive cough since one month. The case was diagnosed by radiological findings, which were suggestive of pulmonary tuberculosis, followed by acid fast staining and culture of the aspirated pericardial fluid. The patient was responding to antitubercular treatment at the last follow up.

A 1-year-old domestic longhair cat presented to our hospital with a 4-month history of progressive exercise intolerance and coughing. Two-dimensional echocardiography confirmed the presence of an intrapericardial cyst and cardiac tamponade. Tamponade was relieved via percutaneous aspiration of the cyst. The cyst was surgically excised 4 days later, and histopathology was consistent with a biliary cyst. The cat's clinical signs completely resolved following surgery.

Pericardial cysts are rare benign intrathoracic lesions, more often located in the right rather than in the left cardiophrenic angle. At echocardiography, they appear as echolucent unilocular structures, which are in contact with the pericardium. They contain a clear water-like fluid and, thus, are referred to as "spring water cysts". They are usually discovered incidentally in asymptomatic patients. Sometimes they can cause symptoms (dyspnea, chest pain, dysphagia, cough), depending on their dimensions and location, or severe complications such as cardiac tamponade. Asymptomatic cases are managed conservatively with a close follow-up, being surgical excision recommended only in symptomatic patients. Actually, the treatment options include excision via thoracotomy, video-assisted thoracoscopic surgery, and percutaneous echo-guided aspiration. We describe the case of a patient for whom the echocardiographic follow-up allowed to disclose intracystic hemorrhage, leading to surgical treatment before the patient became symptomatic.
