Worsened Tricuspid Regurgitation Following Pericardiectomy for Constrictive Pericarditis

Updates on the Global Prevalence and Etiology of Constrictive Pericarditis: A Systematic Review

Constrictive pericarditis is a rare disease with poorly understood epidemiology. A systematic literature search was adopted to assess the region- and period-specific traits of constrictive pericarditis through Pubmed, EMBASE, and Scopus. Case reports and studies including less than 20 patients were excluded. The risk of bias was assessed through the Study Quality Assessment Tools developed by the National Heart Lung Blood Institute by 4 reviewers. Patient demographics, disease etiology, and mortality were the primary assessed outcomes. One hundred thirty studies with 11,325 patients have been included in this systematic review and meta-analysis. The age at diagnosis of constrictive pericarditis has markedly increased after 1990. Patients from Africa and Asia are considerably younger compared with those from Europe and North America. Moreover, there are differences in etiology, as tuberculosis remains the dominant cause of constrictive pericarditis in Africa and Asia but has been surpassed by history of previous chest surgery in North America and Europe. The human immunodeficiency virus affects 29.1% of patients from Africa diagnosed with constrictive pericarditis, a feature that is not observed on any other continent. The early mortality rate after hospitalization has improved. The variances of age at diagnosis and etiology of constrictive pericarditis should be considered by the clinician during the work-up of cardiac and pericardial diseases. An underlying human immunodeficiency virus infection complicates a significant portion of constrictive pericarditis cases in Africa. Early mortality has improved across the world but remains high.

Pericardial Diseases and Best Practices for Pericardiectomy: JACC State-of-the-Art Review

Remarkable advances have occurred in the understanding of the pathophysiology of pericardial diseases and the role of multimodality imaging in this field. Medical therapy and surgical options for pericardial diseases have also evolved substantially. Pericardiectomy is indicated for chronic or irreversible constrictive pericarditis, refractory recurrent pericarditis despite optimal medical therapy, or partial agenesis of the pericardium with a complication (eg, herniation). A multidisciplinary evaluation before pericardiectomy is essential for optimal patient outcomes. Overall, given the good outcomes reported, radical pericardiectomy on cardiopulmonary bypass, if feasible, is the preferred approach. Due to patient complexity, as well as the technical aspects of the surgery, pericardiectomy should be performed at high-volume centers that have the required expertise. The current review highlights the essential features of this multidisciplinary approach from diagnosis to recovery in patients undergoing pericardiectomy.

Surgical Approaches for Pericardial Diseases: What Is New?

PURPOSE OF REVIEW

The purpose of this review is to discuss the evolving techniques and approaches for pericardiectomy, with a focus on the use of cardiopulmonary bypass (CPB) and the extent of radical pericardial resection. The review aims to highlight the benefits and considerations associated with these modifications in radical pericardiectomy.

RECENT FINDINGS

Recent studies have demonstrated that the use of CPB during pericardiectomy does not increase procedural risk or negatively impact survival. In fact, it has been shown to contribute to a more radical resection and improve postoperative outcomes, which is associated with less recurrence and better survival. The review emphasizes the importance of radical pericardiectomy and the use of CPB in achieving successful outcomes. Radical resection of the pericardium, facilitated by CPB, helps minimize the risk of recurrent constrictions and the need for reinterventions. The findings highlight the correlation between postoperative outcomes and survival, further supporting the use of CPB.

Systolic anterior motion due to morphology changes in constrictive pericarditis

Systolic anterior motion (SAM) can be caused by multifactorial mechanisms, including structural, morphological and functional factors. We report an unusual case of a 76-year-old woman presenting with SAM associated with constrictive pericarditis. Echocardiography showed no septal hypertrophy but SAM and left ventricular outflow tract obstruction and moderate mitral regurgitation. The restoration of diastolic function after complete pericardiectomy successfully eliminated it.

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.
