OBJECTIVE: To study the clinical features of pericardial effusion caused by central venous catheterization in preterm infants. METHODS: A retrospective analysis was performed on 11 preterm infants with pericardial effusion caused by central venous catheterization. Their catheterization features, manifestations, treatment, and prognosis were analyzed. RESULTS: A total of 11 preterm infants (11/2 599, 0.42%) developed pericardial effusion, with a mean gestational age of (30.1±2.6) weeks and a mean birth weight of (1 240±234) g. Pericardial effusion mostly occurred within 4 days after central venous catheterization (10 cases, 91%). The main manifestations included poor response (6/11, 55%), cyanosis (5/11, 45%), increased respiratory rate (6/11, 55%), increased heart rate (6/11, 55%), aggravated dyspnea (5/11, 45%), and muffled heart sound (5/11, 45%). At the time of disease progression, 7 preterm infants (64%) had a deep position of the end of the catheter, 3 preterm infants (27%) had a correct position, and 1 preterm infant (9%) had a shallow position. Five preterm infants (45%) experienced cardiac tamponade, among whom 4 underwent pericardiocentesis. Seven preterm infants were given conservative medical treatment. Among the 11 children, 2 (18%) died and 9 (82%) improved. CONCLUSIONS Pericardial effusion caused by central venous catheterization mostly occurs in the early stage of catheterization and has critical clinical manifestations. Pericardiocentesis is required for cardiac tamponade, and early diagnosis and intervention can effectively improve prognosis.

BACKGROUND AND OBJECTIVES: The aim of this study was to investigate the effectiveness and selected adverse events of radiofrequency catheter ablation in patients treated for drug-refractory atrial fibrillation (AF) using claims data provided by the Health Insurance Review and Assessment Service, which covers all ablation procedures conducted in South Korea. SUBJECTS AND METHODS: The study population included patients who underwent catheter ablation for AF between January 2011 and December 2013. A total of 3,850 patients without a previous history of catheter ablation procedure were enrolled. We analyzed 2-year effectiveness of the index ablation. Any redo ablation, electrical cardioversion, or use of antiarrhythmic drug beyond the blanking period of 3 months was considered a failure of index ablation. RESULTS: Overall recurrence rate following AF ablation was 61.1%. The recurrence rate was lower in patients under 65 years old than in those over 65 years old (hazard ratio [HR] 0.89; 95% confidence interval [CI], 0.81 to 0.97, P=0.009). Repeat ablation was more frequent in men (HR 1.56; 95% CI, 1.20 to 2.04; P=0.001) and patients under 65 years old (HR 1.79; 95% CI, 1.34 to 2.38; P < 0.001). Electric cardioversion was more frequent in men (HR 1.35; 95% CI, 1.06 to 1.72; P=0.014) than in women. The overall rate of stroke, blood transfusion, significant pericardial complication, and cardiopulmonary resuscitation was 0.5%, 4.8%, 2.7%, and 0.2%, respectively. CONCLUSIONS: In the present study, old age was associated with treatment failure of catheter ablation for drug-refractory AF in the Korean population. Overall recurrence did not vary with respect to sex.

A 13-year-old spayed female Miniature Schnauzer was presented with complaints of intermittent syncope. Pericardial effusion was confirmed based on the physical examination, thoracic radiographs and echocardiography. Subsequently, prompt pericardiocentesis was performed. Clinical abnormalities were immediately improved after pericardiocentesis. However, the clinical signs associated with acute collapse recurred. After the second pericardiocentesis, thoracic radiographs revealed pleural effusion, and the clinical signs resolved rapidly. The dog underwent pleural aspiration. Analysis of pleural fluid revealed almost similar features as the previous pericardial fluid. It was possible that a pericardial-pleural fistula was created during the pericardiocentesis. The pericardial and pleural effusion disappeared after the procedures.

Pericardial drainage is an important diagnostic and therapeutic option in the symptomatic patient with large amount of pericardial effusion (PE). However, when the amount of PE is relatively small, physicians are often reluctant to perform the invasive drainage of the fluid due to the increased risk of causing myocardial injury during the procedure. Even in some cases of suspected pericarditis with small amount PE, an initial empirical anti-inflammatory therapy is often recommended. A 65-year-old woman presented with mild dyspnea for two weeks. The echocardiography revealed small amount of PE. A careful fluoroscopy-guided pericardiocentesis, subsequent pericardial fluid cytology, and thorough whole body check-up demonstrated adenocarcinoma with no proven primary site. After the palliative chemotherapy, she had survived for 15 months until her death due to asphyxia. Although pericardiocentesis is considered dangerous in small amount of PE, a prompt and careful drainage may provide early detection of hidden malignancy and better survival outcome.

Rivaroxaban is a new oral anticoagulant used for the prevention of stroke in patients with atrial fibrillation. Hemorrhagic pericarditis is known to occur with rivaroxaban; however, only a few case reports in the literature describe such events. Recently, we experienced hemorrhagic pericarditis that treated with rivaroxaban for anticoagulation of newly diagnosed, non valvular AF patients with pacemaker. An 83 year old male with permanent pacemaker receiving rivaroxaban 20 mg daily once for 3 months presented at our emergency department complaining of exertional dyspnea. ECG showed intermittent atrial pacing failure and echocardiography showed large amount of pericardial effusion. After urgent pericardiocentesis, which resulted in removal of 500cc bloody fluid, there was an immediate and dramatic improvement in the patient's clinical state. He was discharged without anticoagulation therapy due to concern for further bleeding. This case highlight the potential for bleeding complications associated with novel anticoagulants. Rivaroxaban is being used with increasing frequently in outpatient care. However, no available laboratory test specifically measures the anticoagulant effect of rivaroxaban. Also, in the events of serious bleeding, no specific antidotes, reversal agents were available. Clinicians should be aware of the possibility of hemopericardium in patients treated with anticoagulants, including rivaroxaban who presented with cardiomegaly.

OBJECTIVE: Our objective was to determine the utility of point-of-care ultrasound (POCUS) to identify and guide treatment of tamponade or clinically significant pericardial effusions in the emergency department (ED). METHODS: This was a retrospective cohort study of non-trauma patients who were diagnosed with large pericardial effusions or tamponade by the ED physician using POCUS. The control group was composed of those patients later diagnosed on the medical wards or incidentally in the ED by other means such as a computed tomography. The following data were abstracted from the patient’s file: demographics, medical background, electrocardiogram results, chest radiograph readings, echocardiogram results, and patient outcomes. RESULTS: There were 18 patients in the POCUS arm and 55 in the control group. The POCUS arm had a decreased time to pericardiocentesis (11.3 vs. 70.2 hours, P=0.055) as well as a shorter length of stay (5.1 vs. 7.0 days, P=0.222). A decreased volume of pericardial fluid was drained (661 vs. 826 mL, P=0.139) in the group diagnosed by POCUS. CONCLUSION: This study suggests that POCUS may effectively identify pericardial effusions and guide appropriate treatment, leading to a decreased time to pericardiocentesis and decreased length of hospital stay. Pericardial tamponade or a large pericardial effusion should be considered in all patients presenting to the ED with clinical, radiographic, or electrocardiographic signs of cardiovascular compromise.

Myocardial rupture is a rare but lethal complication of myocardial infarction. Immediate conservative management is critical, but surgery should be considered if the patient's hemodynamic state and degree of hemopericardium do not improve after pericardiocentesis. In this case, a 54-year old patient without underlying disease came to the emergency after experiencing chest pain for two weeks with suddenly aggravated severe dyspnea. The patient was found to have a hemopericardium with cardiac tamponade, so pericardiocentesis was immediately executed. Transthoracic echocardiogram revealed akinesia of the left ventricular muscle and focal wall thinning. The patient was diagnosed with complete occlusion of a single diagonal branch and ventricular free wall rupture using a coronary computed tomography scan. After conservative treatment, vital signs and cardiac function stabilized, and there was no definitive sequela. This case is clinically significant because myocardial rupture, a lethal complication of myocardial infarction, was successfully managed with non-surgical, conservative treatment.

Pneumopericardium is defined by the presence of air in the pericardial cavity. It is a rare entity occurring most commonly after trauma. Pneumopericardium resulting after pericardiocentesis is even rarer. We report a case of 46-year-old man, with end-stage renal disease on chronic hemodialysis and who developed a large circumferential pericardial effusion of 40 mm in diastole with swinging heart and diastolic right atrium collapse requiring pericardiocentesis. Few days after, the patient complained of pleuritic chest pain and echocardiogram revealed several tiny sparkling echogenic spots swirling in the pericardial sac. Computed tomography scans revealed a marked anterior pneumopericardium that was conservatively managed.

Pneumopericardium is defined as the presence of air inside the pericardial space. Usually, it is reported as a complication of blunt or penetrating chest trauma, but rare iatrogenic and spontaneous cases have been reported. Pneumopericardium is relatively stable if it does not generate a tension effect on the heart. However, it may progress to tension pneumopericardium, which requires immediate pericardial aspiration. We report a case of iatrogenic pneumopericardium occurred in a 70-year-old man who presented dyspnea at emergency department. The patient underwent pericardiocentesis for cardiac tamponade due to large pericardial effusion, and iatrogenic tension pneumopericardium occurred due to misuse of the drainage device. After evacuating the pericardial air through the previously implanted catheter, the patient became stable. We report this case to increase the awareness of this fatal condition and to help increase the use of precautions against the development of this condition during emergency procedures.

Although the incidence of uremic pericarditis was high in the past, it has decreased in recent decades with early and appropriate dialysis. However, cardiac tamponade caused by uremic pericarditis is still a life-threatening emergency and it requires urgent management. Herein we report a case of 38-year-old man with chronic renal disease who represented critical uremic pericarditis followed by cardiac tamponade despite of appropriate hemodialysis. Careful consideration of risk factors and aggressive treatment are very important for effective and safe treatment of uremic pericarditis and cardiac tamponade.
