Anterior Pericardiectomy for Postinfective Constrictive Pericarditis: Intermediate-Term Outcomes

Anesthesia management for pericardiectomy- a case series study

BACKGROUND

Constrictive pericarditis (CP) is an uncommon disease that limits both cardiac relaxation and contraction. Patients often present with right-sided heart failure as the pericardium thickens and impedes cardiac filling. Pericardiectomy is the treatment of choice for improving hemodynamics in CP patients; however, the procedure carries a high morbidity and mortality, and the anesthetic management can be challenging. Acute heart failure, bleeding and arrhythmias are all concerns postoperatively.

METHODS

After IRB approval, we performed the retrospective analysis of 66 consecutive patients with CP who underwent pericardiectomy from July 2018 to May 2022.

RESULTS

Most patients had significant preoperative comorbidities, including congestive hepatopathy (75.76%), New York Heart Association Type III/IV heart failure (59.09%) and atrial fibrillation (51.52%). Despite this, 75.76% of patients were extubated within the first 24 h and all but 2 of the patients survived to discharge (96.97%).

CONCLUSIONS

Anesthetic management, including a thorough understanding of the pathophysiology of CP, the use of advanced monitoring and transesophageal echocardiography (TEE) guidance, all played an important role in patient outcomes.

Pericardiectomy and Pericardial Window for the Treatment of Pericardial Disease in the Contemporary Era

PURPOSE OF REVIEW

To summarize the contemporary practice of pericardiectomy and pericardial window. We discuss the indications, preoperative planning, procedural aspects, postprocedural management, and outcomes of each procedure.

RECENT FINDINGS

Surgical approaches for the treatment of pericardial disease have been around even before the emergence of cardiopulmonary bypass. Since the forthcoming of cardiopulmonary bypass, there have been significant changes in the epidemiology and diagnostic approach of pericardial diseases as well as advancements in the surgical techniques and perioperative management used in the care of these patients. Pericardiectomy has an average mortality of almost 7% and is typically performed in patients with advanced symptoms from constrictive pericarditis and relatively few comorbidities. Pericardial window is a safe procedure for the treatment of pericardial effusion that can be performed with different approaches.

Does tuberculosis affect surgical outcomes following pericardiectomy for chronic constrictive pericarditis? Twelve years’ experience from a tertiary care center in India

Introduction and purpose

Tuberculosis (TB) is the commonest cause of chronic constrictive pericarditis (CCP) in India, unlike in the western countries. Pericardiectomy is the treatment of choice for CCP. Surgery in TB CCP is considerably more difficult than it is for other etiologies. The role of TB as an independent predictor for adverse surgical outcomes had not been properly evaluated in the Indian scenario. Hence, the aim of this study was to retrospectively analyze our results of surgery for CCP and the pre-operative factors that influenced post-operative outcomes.

Methods

The data of all adult patients who underwent pericardiectomy for CCP, between the years 2009 and 2020, maintained in a live database in our institute, were retrieved and analyzed.

Results

There were 124 patients in the study. The average age was 32 years. The male to female ratio was 3:1. TB was the commonest cause of CCP, identified in 64 (51.6%) patients. Complete anterior pericardiectomy (CAP) was possible in 122 (98.3%) patients. All the patients had significant drop in their central venous pressure (CVP) (10.25 ± 3.47 mmHg) after surgery. The operative time (p = 0.008), intra-operative blood loss (p = 0.02), intensive care unit (ICU) stay (p = 0.03), and hospital stay (p = 0.028) were significantly higher in the TB group. Apart from TB, the other pre-operative variables that predicted adverse outcomes were male sex, presence of pleural effusion or ascites, and advanced New York Heart Association (NYHA) class. There were 7 (5.6%) post-operative complications and 3 (2.4%) in-hospital deaths.

Conclusion

The high incidence of TB CCP makes a pericardiectomy in developing countries technically more challenging resulting in increased operative time, more blood loss, and prolonged ICU and hospital stay, but did not affect in-hospital mortality or morbidity.

Pericardiectomy for Constrictive Tuberculous Pericarditis: A Systematic Review and Meta-analysis on the Etiology, Patients' Characteristics, and the Outcomes

Tuberculosis (TB) is the most common etiology of constrictive pericarditis in the developing world. In this study, we collected currently available data to evaluate the outcomes following pericardiectomy in patients with constrictive tuberculous pericarditis. We retrieved electrical databases, including PubMed and PubMed Central, from 1985 AD and onwards. We included articles that had more than 80% TB as the etiology and articles with mixed etiologies. Pooled analysis was done in Review Manager (RevMan) version 5.2 (The Nordic Cochrane Centre, Copenhagen). and Stata Statistical Software, Release 16 ( StataCorp LLC, College Station, TX). We compared the mortality in patients after pericardiectomy due to TB with other etiologies. In-hospital mortality versus one-year mortality was analyzed in studies with constrictive pericarditis of mixed etiologies. We also compared pre-operative New York Heart Association (NYHA) grade to post-operative NYHA grade one year after pericardiectomy. We calculated the pooled mean of postoperative hospital stay, postoperative intensive care unit (ICU) stay, and in-hospital mortality. A total of 12 articles and 859 patients were included in the final analysis. Pericardiectomy was performed mostly on middle-aged men with or without previous comorbidity. Total pericardiectomy was the preferred surgical procedure performed on a mean of 93% of patients. The pooled analysis shows a significant decrease in all-cause mortality in patients with TB as compared to other etiologies (pooled risk ratios (RR) 0.34 CI [0.12,1.01] I2 = 61%) and a lower but insignificant in-hospital mortality in comparison to one-year mortality in studies with mixed etiologies (RR 0.59 [0.11,3.11] I2= 61%). There was a significant improvement in the NYHA grade of the patients one year following pericardiectomy (RR 8.04, CI [5.20,12.45], I2= 0%). The mean postoperative hospital stay and the postoperative ICU stay were calculated and reported in terms of days. The mean postoperative hospital stays in studies with more than 80% of TB cases is 13.34 (10.21, 16.47) with a mean standard deviation of 4.46 (2.87, 6.05). The mean postoperative ICU stay is 1.93 (1.47, 2.39), with a mean standard deviation of 3.26 (2.51, 4.00), and the mean in-hospital mortality is 0.07 (0.02, 0.12). Similarly, the mean postoperative hospital stay in studies with mixed etiologies is 19.40 (11.93, 26.87) with a mean standard deviation of 8.26 (4.21, 12.52). The mean postoperative ICU stay is 3.52 (1.93, 5.10) with a mean standard deviation of 2.34 (1.36, 3.32). The mean in-hospital mortality is 0.06 (0.04, 0.08). There is significant heterogeneity along with a number of methodological concerns, and therefore, generalization of the data should be done with caution, and a randomized controlled trial in the future may be beneficial.

Fifteen-year experience with pericardiectomy at a tertiary referral center

Purpose

Pericardiectomy has traditionally carried relatively high perioperative mortality and morbidity, with few published reports of intermediate- and long- term outcomes. We investigated our 15-year experience performing pericardiectomy at our institution.

Methods

Retrospective study of all patients who underwent pericardiectomy at our institution between 2005 and 2019. Baseline demographics, intraoperative details, and postoperative outcomes including long-term survival were analyzed.

Results

Sixty-three patients were included in the study. 66.7% of subjects underwent isolated pericardiectomy while 33.3% underwent pericardiectomy concomitantly with another cardiac surgical procedure. The most common indications for pericardiectomy were constrictive (79.4%) and hemorrhagic (9.5%) pericarditis. Preoperatively, 76.2% of patients were New York Heart Association class II and III, while postoperatively, 71.4% were class I and II. One-, three-, five-, and ten- year overall mortality was 9.5, 14.3, 20.6, and 25.4%, respectively. Overall pericarditis recurrence rate was 4.8%.

Conclusion

Pericardiectomy carries relatively high overall mortality rates, which likely reflects underlying disease etiology and comorbidities. Patients with prior cardiac intervention, history of dialysis, and immunocompromised state are associated with worse outcomes.

Pericardiectomy for Constrictive Pericarditis: Analysis of Outcomes

Constrictive pericarditis is caused by pericardial inflammation and fibrosis, leading to diastolic heart failure. The diagnosis requires a high index of suspicion because it often can mimic restrictive myocardial disease and cardiac tamponade and can be associated with severe tricuspid regurgitation and chronic liver disease. Patients who remain undiagnosed can experience a 90% mortality rate, and for those who undergo pericardiectomy, the survival rate varies significantly, depending on the underlying etiology and preoperative functional class of the patient. In this article, the authors review the pathophysiology, echocardiographic findings, management, and surgical outcomes of constrictive pericarditis to aid the cardiothoracic anesthesiologist in the perioperative management of this disorder.

Constrictive Pericarditis After Lung Transplantation

BACKGROUND

Constrictive pericarditis is a rare, but increasingly recognized long-term postoperative complication of lung transplantation. Heightened clinical suspicion, improved diagnostic imaging, and effective surgical treatment of the disease have led to progressive awareness of the pathology. We present our institutional experience with constrictive pericarditis after lung transplant in an effort to investigate the cause and natural history of the disease.

METHODS

From October 2005 to October 2018, 1234 patients underwent orthotopic lung transplantation at Duke University Hospital. An institutional database was queried to identify incident patients and determine baseline clinical data. At a median of 11.2 months (interquartile range = 4.6-28.6 mo), 10 patients (0.8%) developed constrictive pericarditis. Simple descriptive statistics were used to describe cohort characteristics and identify variables associated with constrictive pericarditis after lung transplantation.

RESULTS

The indication for transplantation at index operation was idiopathic pulmonary fibrosis in 8 of 10 patients (1.2% of the 760 restrictive lung disease patients transplanted in the same time period). All 10 patients presented with worsening dyspnea and pleural effusions. Right heart catheterization confirmed constrictive physiology in all cases. Eight patients underwent pericardiectomy with improvement in cardiovascular hemodynamics and resolution of symptoms with no 30-day mortality.

CONCLUSIONS

Diagnosis of constrictive pericarditis should be considered in patients with new-onset heart failure symptoms or recurrent pleural effusions within 2 years of lung transplantation. Idiopathic pulmonary fibrosis may be associated with increased risk for constrictive pericarditis. Pericardiectomy is a safe and effective treatment for posttransplant constrictive pericarditis.

Predictors of postoperative complication and prolonged intensive care unit stay after complete pericardiectomy in tuberculous constrictive pericarditis

Background

The risk factors of postoperative outcomes after pericardiectomy in tuberculous constrictive pericarditis have still been unclear. This study aimed to investigate the predictors of postoperative complication and prolonged intensive care unit (ICU) stay in the patients with tuberculous constrictive pericarditis undergoing pericardiectomy.

Methods

A total of 88 patients with tuberculous constrictive pericarditis undergoing pericardiectomy were retrospectively enrolled. Logistic regression and Cox regression analysis were performed to identify the predictors of postoperative complication and prolonged ICU stay, respectively.

Results

All patients underwent complete pericardiectomy and 35 (39.8%) had postoperative complication with no mortality within 30 days after surgery and no in-hospital deaths. Postoperative complication prolonged postoperative ICU stay (P < 0.001), duration of chest drainage (P < 0.001) and postoperative hospital stay (P < 0.001). Preoperative NYHA functional class (P = 0.004, OR 4.051, 95%CI 1.558–10.533) and preoperative central venous pressure (CVP) (P = 0.031, OR 1.151, 95%CI 1.013–1.309) were independent risk factors of postoperative complication. Postoperative complication (P < 0.001, HR 4.132, 95%CI 2.217–7.692) was the independent risk factor for prolonged ICU stay.

Conclusion

Complete pericardiectomy was associated with high risk of postoperative complication in tuberculous constrictive pericarditis. Poor preoperative NYHA functional class and high preoperative CVP were shown to predict postoperative complication which was the predictor of prolonged ICU stay.
