Severe right ventricular and tricuspid valve dysfunction after pericardiocentesis

Pericardiocentesis is performed to treat cardiac tamponade or diagnose the cause of pericardial effusion. Cardiogenic shock with right ventricular (RV) dysfunction is a rare complication after pericardiocentesis. We report a case of an 82-year-old man who suddenly suffered cardiopulmonary arrest 12 h after pericardiocentesis. A transthoracic echocardiogram showed remarkable RV dysfunction and tricuspid valve dysfunction. Tricuspid valve closure was severely impaired, and the tricuspid regurgitation signal showed laminar flow with an early peak. However, after treatment with high-dose inotropic drugs, hemodynamic parameters gradually recovered. A transthoracic echocardiogram performed 24 h later showed improved motion of the RV and the tricuspid valve, resulting in a reduction in tricuspid regurgitation. RV and tricuspid valve dysfunction after pericardiocentesis needs to be recognized as a critical complication. Physicians also need to pay attention to not only the amount of drainage but also underlying RV dysfunction.

Choice of drainage procedure in paediatric pyopericardium: a 30-year experience

Although there is general agreement on the necessity of draining pyopericardium, debate continues as to the safe and effective method of drainage. Studies describing head-to-head comparison of various drainage procedures are very few and are disadvantaged by small numbers of cases. In this observational study, we review our 30-years experience with different techniques of pericardial drainage. Between 1972 and 2003, the authors have personally treated 39 children who suffered from pyopericardium. Among the 22 children who underwent early partial pericardiectomy, 20 were alive. In contrast to this,12 out of 15 children treated with repeated pericardiocentesis or sub-xiphoid tube drainage were dead. The median hospital stay for pericardiectomy group was 18 days (range 11-32) and that for the non-thoracotomy group was 34 days (range 18-55 days).

With regard to immediate survival and early convalescence in the pyopericardium, partial pericardiectomy is superior to pericardiocentesis and sub-xiphoid tube drainage. Pericardiocentesis can be used for diagnostic or temporizing purposes, but not as the definitive drainage procedure. Partial pericardiectomy can be done even in small hospitals where heart-lung machines are not available.

Differential Impact of Constrictive Physiology after Pericardiocentesis in Malignancy Patients with Pericardial Effusion

BACKGROUND

Echocardiographic signs of constrictive physiology (CP) after pericardiocentesis are frequently observed in malignancy patients. The purpose of the current study was to explore whether features of CP after pericardiocentesis have prognostic impact in malignancy patients with pericardial effusion (PE).

METHODS

We retrospectively reviewed 467 consecutive patients who underwent pericardiocentesis at our institution from January 2006 to May 2014. Among them, 205 patients with advanced malignancy who underwent comprehensive echocardiography after the procedure comprised the study population. Co-primary end points were all-cause mortality (ACM) and repeated drainage (RD) for PE. Patients were divided into four subgroups according to cytologic result for malignant cells and CP (positive cytology with negative CP, both positive, both negative, and negative cytology with positive CP).

RESULTS

CP after pericardiocentesis was present in 106 patients (50%) at median 4 days after the procedure. During median follow-up of 208 days, ACM and RD occurred in 162 patients (79%) and 29 patients (14%), respectively. Cox regression analysis revealed that independent predictors for ACM were male gender and positive cytology (all, p < 0.05). For RD, predictors were positive cytology, the absence of cardiac tamponade, and negative CP after pericardiocentesis (all, p < 0.05). When the patients were divided into four subgroups, patients with negative cytology and positive CP demonstrated the most favorable survival (hazard ratio [HR]: 0.39, p = 0.005) and the lowest RD rates (HR: 0.07, p = 0.012).

CONCLUSION

CP after pericardiocentesis is common, but does not always imply poor survival or the need for RD in patients with advanced malignancies. On the contrary, the presence of CP in patients with negative cytology conferred the most favorable survival and the lowest rate of RD. Comprehensive echocardiographic evaluation for CP after pericardiocentesis would be helpful for predicting prognosis in patients with advanced malignancies.

Real-time cardiovascular magnetic resonance subxiphoid pericardial access and pericardiocentesis using off-the-shelf devices in swine

BACKGROUND

Needle access or drainage of pericardial effusion, especially when small, entails risk of bystander tissue injury or operator uncertainty about proposed trajectories. Cardiovascular magnetic resonance (CMR) might allow enhanced imaging guidance.

METHODS AND RESULTS

We used real-time CMR to guide subxiphoid pericardial access in naïve swine using commercial 18G titanium puncture needles, which were exchanged for pericardial catheters. To test the value of CMR needle pericardiocentesis, we also created intentional pericardial effusions of a range of volumes, via a separate transvenous-transatrial catheter. We performed these procedures in 12 animals.

CONCLUSIONS

CMR guided pericardiocentesis is attractive because the large field of view and soft tissue imaging depict global anatomic context in arbitrary planes, and allow the operator to plan trajectories that limit inadvertent bystander tissue injury. More important, CMR provides continuous visualization of the needle and target throughout the procedure. Using even passive needle devices, CMR enabled rapid pericardial needle access and drainage. We believe this experience supports clinical testing of real-time CMR guided needle access or drainage of the pericardial space. We suspect this would be especially helpful in "difficult" pericardial access, for example, in distorted thoracic anatomy or loculated effusion.

Cardiac tamponade likely due to candida infection, in an immunocompetent patient

Candida pericarditis is a rare disease described mainly in immunodepressed patients. Here we report the case of a 76-year-old immunocompetent woman who developed a purulent pericarditis 48 hours after pericardiocentesis. Usual etiologies such as cancer or pericardo-oesophageal fistula, were ruled out. Physical examination revealed a sub-mammary mycosis, which could have led to the infection. The early diagnosis and treatment with a combined medical and surgical approach succeeded in a favorable evolution of this case.

Comparison of surgical pericardial drainage with percutaneous catheter drainage for pericardial effusion

OBJECTIVE

We sought to investigate the outcomes for different treatments of pericardial effusions.

BACKGROUND

The optimal initial management for symptomatic pericardial effusions remains controversial.

METHODS

We performed a 3-year retrospective, single-institution study comparing open surgical drainage to percutaneous pericardiocentesis for symptomatic pericardial effusions.

RESULTS

Between 2007 and 2009, a total of 193 patients underwent an initial drainage procedure for a pericardial effusion (n = 121 [62.7%] pericardiocentesis; n = 72 [37.3%] open surgical drainage). Compared to those treated with pericardiocentesis, treatment with open surgical drainage was associated with a higher complication rate (4.9% vs 26.4%; P<.0001; odds ratio [OR], 6.9; 95% confidence interval [CI], 2.6-18.2). Treatment with pericardiocentesis was associated with a higher rate of repeat procedures to drain a recurrent effusion compared to open surgical drainage (28.9% vs 2.8%; P<.0001; OR, 14.2; 95% CI, 3.3-61.3). Thirty-day mortality (19.8% surgical group vs 18.1% pericardiocentesis group; P=.8) and long-term survival (P=.4) did not differ between the groups.

CONCLUSION

There is no significant difference in overall mortality between open surgical drainage and percutaneous pericardiocentesis for symptomatic pericardial effusions. There may be more procedural complications following surgical drainage of a pericardial effusion, and a greater need for repeat procedures if the effusion is drained using pericardiocentesis.

Pericardiocentesis in contemporary practice

OBJECTIVE

Pericardiocentesis is a life-saving procedure associated with a small, but significant, risk of major complication. An apical or subcostal approach may be used, although the relative complication rates are not reported. In modern practice, an increasing proportion of pericardial effusions occur as a result of catheter-laboratory related complications. This study examines current practice and analyzes the complications of pericardial drainage according to the route of approach.

DESIGN

Historical cohort study.

SETTING

Four Oxfordshire hospitals, including the John Radcliffe Hospital, a tertiary referral center.

PATIENTS

Local databases were searched to identify percutaneous pericardiocenteses carried out between November 2002 and October 2009.

RESULTS

A total of 188 pericardiocenteses were performed in 163 patients. Malignancy (55; 33.7%) and catheter-based cardiac procedures (45; 23.9%) were the most common causes of pericardial effusions requiring drainage. 50.0% of all pericardiocenteses were performed in patients who had received anticoagulant or antiplatelet agents the same day. This rose to 93.7% in patients whose effusions occurred as a complication of a catheter-based procedure. Nine complications occurred during the study period, giving an overall complication rate of 4.8%. Six of the complications occurred via the subcostal route and all 4 complications requiring surgery occurred via the subcostal route.

CONCLUSION

The numbers of iatrogenic pericardial effusions occurring as a complication of catheter-based procedures mean that a significant proportion of pericardiocenteses are being performed in anticoagulated patients. This may alter the risk profile. Although complication rates were low for both routes, all major complications requiring surgery occurred via the subcostal approach. These data suggest an apical approach may be preferable where practical.

[Surgical treatment of iatrogenic cardiac injury induced by pericardiocentesis; report of a case]

We reported a case of surgical treatment of iatrogenic cardiac injury. A 67-year-old man with cardiac tamponade was treated by pericardiocentesis. At night he was transferred to our hospital for emergent treatment of shock state. We found the pericardiocentesis drainage tube perforated left ventricle on computed tomography (CT). This perforation was repaired on the beating heart state using 5-0 monofilament mattress sutures reinforced by felt pledgets. Fatal complications might not occur when appropriate procedures are followed during the placement of a catheter for pericardiocentesis. Iatrogenic cardiac injury is rare but nevertheless requires caution.

Tension pneumopericardium after removal of pericardiocentesis drainage catheter

This image showed tension pneumopericardium caused by removing the pericardiocentesis catheter, which was inserted to drain malignant pericardial effusion. Tension pneumopericardium is a rare and potentially fatal event. Mortality from tension pneumopericardium can be as high as 50%. Therefore, it is important to suspect and detect early, if the patient complained of dyspnea after removing the pericardiocentesis drainage catheter.

Intracardiac shunt with hypoxemia caused by right ventricular dysfunction following pericardiocentesis

Significant hypoxemia can result from right-to-left intracardiac shunting through a patent foramen ovale, an atrial septal defect or a ventricular septal defect. Pulmonary embolus, congenital heart disease and pericardial tamponade are well-recognized causes of right-to-left shunting. However, right-to-left shunting can also follow pericardiocentesis. A case of profound hypoxemia caused by right ventricular hypokinesis precipitated by pericardial tap is reported. This under-recognized entity can be responsible for significant morbidity in the critical care setting. The clinical presentation, natural history, diagnosis and treatment of hypoxemia caused by intracardiac shunt following pericardiocentesis are discussed.

Pericardiocentesis practice in the United Kingdom

BACKGROUND

Pericardial effusions frequently present challenging clinical dilemmas. Whether or not to drain an effusion, and if so by what method, are two common decisions facing cardiologists. We performed a survey to evaluate pericardiocentesis practice in the United Kingdom (UK).

METHODS

A total of 640 questionnaires were sent to all cardiologists in the UK Directory of Cardiology in March 2003.

RESULTS

A total of 274 (43%) completed questionnaires were returned, 88% from consultants, equally distributed between tertiary referral centres and district general hospitals. More than 1500 procedures were performed, largely using a paraxiphoid approach (89%). Clinical tamponade was the commonest indication for pericardiocentesis (83%). However, the majority of respondents (69%) considered echocardiographic features alone an indication for pericardiocentesis, even in the absence of clinical tamponade. The commonest perceived indications for drainage were right ventricular diastolic collapse and right atrial collapse (69% and 33% of respondents respectively). For guidance, 82% use echocardiography, either alone or with fluoroscopy or the electrocardiogram (ECG) injury trace. 11% employ fluoroscopy alone or with the ECG injury trace. The remaining 11% stated that they would use the ECG injury trace alone or use no guidance. Using the ECG injury trace alone is said by the European Society of Cardiology (ESC) guidelines to offer an inadequate safeguard. Reported complications included ventricular puncture (n = 12, 0.8%) and hepatic damage (n = 4, 0.3%).

CONCLUSION

Pericardiocentesis practice varies substantially in the UK. Many cardiologists would perform pericardiocentesis based on echocardiographic features alone. 11% of cardiologists use guidance that is considered inadequate by the ESC guidelines.

The management of tuberculous pericardial effusion: experience in 233 consecutive patients

AIM

We report on the 30-day and one-year outcome of consecutive effusive pericarditis patients, including those with tuberculous pericarditis, over a six-year-period.

METHODS AND RESULTS

Patients with large pericardial effusions requiring pericardiocentesis were included in the study after having given written informed consent. Clinical and radiological evaluations were followed by echo-guided pericardiocentesis, and extended daily intermittent drainage via an indwelling pigtail catheter. A standard short-course anti-tuberculous regimen was initiated. A total of 233 patients was included. One hundred and sixty-two patients had pericardial tuberculosis (TB), including 118 (73%) with microbiological and/ or histological evidence of TB and 44 (27%) diagnosed on clinical and supportive laboratory data. Over the six-year period, two patients developed fibrous constrictive pericarditis after receiving adjuvant corticosteroid therapy. The 30-day mortality (8.0%) was statistically higher for HIV-positive patients (corresponding mortality 9.9%) than for HIV-negative patients (6.2%; p = 0.04). The one year all-cause mortality was 17.3%. It was also higher for HIV-positive (22.2%) than for IV-negative patients (12.3%; p = 0.03). Cardiac mortality was equal for HIV-positive and -negative patients.

CONCLUSION

Tuberculous pericardial effusions responded well to closed pericardiocentesis and a six-month treatment of antituberculous chemotherapy. The former was effective and safe irrespective of HIV status.

Echocardiographically guided pericardiocentesis for treatment of clinically significant pericardial effusion in rheumatoid arthritis

OBJECTIVE

To assess the safety and efficacy of echocardiographically guided pericardiocentesis for patients with rheumatoid arthritis (RA) and hemodynamically significant pericardial effusion.

METHODS

We identified 16 patients with RA who underwent 18 echocardiographically guided pericardiocentesis procedures at our institution over a 20-year period. Clinical and laboratory characteristics of the patients, response to treatment, complications, and need for future pericardial surgery were abstracted from the echocardiography database.

RESULTS

Ten patients were men and 6 were women (mean age, 62 yrs; range, 36-75 yrs). On average, patients were diagnosed with RA 11 years before pericardial disease developed. Twelve of 15 patients were seropositive for rheumatoid factor, 10 patients had radiographic evidence of erosions, and 7 patients had rheumatoid nodules. Cardiac tamponade was present in 11 of the 18 cases. Mean volume drained on the first pericardiocentesis was 504 +/- 264 ml (range 120-1000 ml). The fluid was an exudate with a mean protein concentration of 5 g/dl (range 3.3-51.1 g/dl). All cultures and cytologic findings were negative for bacteria and neoplastic cells. No serious complications resulted from echocardiographically guided pericardiocentesis. For 11 patients, a catheter was placed for intermittent drainage over an average of 3 days. Seven patients ultimately required a more definitive surgical procedure.

CONCLUSION

Echocardiographically guided pericardiocentesis is a safe and effective treatment for this uncommon but serious complication of RA.

A cadaveric study of complications associated with the subxiphoid and transthoracic approaches to emergency pericardiocentesis

OBJECTIVES

The aim of this cadaveric study was to compare three commonly used approaches for emergency pericardiocentesis and to determine the safest approach.

METHODS

Thirteen cadavers were injected at three sites with three different coloured dyes, one for each of the three different recommended approaches. The approaches used were (1) ATIP: anterior transthoracic in the fifth left intercostal space (Advanced Cardiac Life Support protocol), (2) SXP1: immediately subxiphoid and (3) SXP2: subxiphoid approach 1.5 cm inferior to SXP1 (Advanced Trauma Life Support protocol). The needles were left in the chest cavity to confirm their course on the way into the pericardial sac. Once the chest plate was removed, the location of the needle and the presence of dye enabled the identification of structures damaged and cavities entered by the needle. The associated complications from the three approaches were then recorded and compared.

RESULTS

The anterior transthoracic intercostal pericardiocentesis approach to pericardiocentesis (2/39) and an immediately subxiphoid approach SXP1 (1/39) produced fewer potential complications than SXP2 (4/39).

CONCLUSIONS

The SXP1 approach appeared to be the safest, followed by anterior transthoracic intercostal pericardiocentesis. The SXP2 approach caused the highest amount of complications, resulting from the needle entering the abdominal cavity. The presence of intra-abdominal pathology and the possibility of post-mortem changes in the position of the diaphragm, however, might have been a causative factor in this finding.

Chronic Expanding Intrapericardial Hematoma After Pericardial Paracentesis

Chronic expanding intrapericardial hematoma (CEIH) is rare. A thorough search of literature revealed a few cases after open heart surgery, chest trauma, or epicardial injury. We report the case of a 72-year-old man presenting with a large CEIH and constrictive pericarditis, who had no past history of the above conditions but had undergone pericardiocentesis four years earlier. The cause of the initial hemorrhage of the hematoma might be due to a scratch by a needle during pericardial paracentesis. The hematoma had expanded during a course of four years. The hematoma was removed surgically, and there has been no sign of recurrence 17 months after the operation.
