Anti-inflammatory properties of amniotic membrane patch following pericardiectomy for constrictive pericarditisMarsh, Katherine M., Ferng, Alice S., Pilikian, Tia, Desai, Ankit A., Avery, Ryan, Friedman, Mark, Oliva, Isabel, Jokerst, Clint, Schipper, David, Khalpey, Zain 26 January 2017 (has links)
Background: Since constrictive pericarditis is most often idiopathic and the pathophysiology remains largely unknown, both the diagnosis and the treatment can be challenging. However, by definition, inflammatory processes are central to this disease process. Amniotic membrane patches have been shown to possess anti-inflammatory properties and are believed to be immune privileged. Due to these properties, amniotic membrane patches were applied intraoperatively in a complicated patient presenting with constrictive pericarditis. Case presentation: A patient with a history of multiple cardiac surgeries presented with marked fatigue, worsening dyspnea and sinus tachycardia. He was found to have constrictive physiology during cardiac catheterization, with cardiac MRI demonstrating hepatic vein dilatation, atrial enlargement and ventricular narrowing. After amniotic membrane patch treatment and pericardiectomy, post-operative cardiac MRI failed to demonstrate any appreciable pericardial effusion or inflammation, with no increased T2 signal that would suggest edema. Conclusions: Given the positive results seen in this complex patient, we suggest continued research into the beneficial properties of amniotic membrane patches in cardiac surgery.

Constrictive Pericarditis: A Commonly Missed Cause of Treatable Diastolic Heart FailureBhattad, Pradnya B., Jain, Vinay 08 May 2020 (has links)
Constrictive pericarditis arises as a result of the fibrous thickening of the pericardium due to chronic inflammatory changes from various injuries. Increased pulmonary and systemic venous pressures manifest clinical features of left and right heart failure. Idiopathic or post-viral pericarditis is the most common cause followed by postpericardiotomy, radiation-induced causes. Right-sided heart failure symptoms predominate over left-sided heart failure symptoms due to the equalization of pressures. No single diagnostic test can provide a definitive diagnosis or evidence of constrictive pericarditis. Medical management is difficult for constrictive pericarditis. The treatment of choice for constrictive pericarditis is pericardiectomy.

All-cause Mortality after Pericardiectomy for Chronic Constrictive Pericarditis in a Single-Center CohortPenov, Kiril 02 February 2018 (has links)
Constrictive pericarditis (CP) is an uncommon disease with multiple causes and discrepant clinical outcome. Till date, there is a scarcity of publications, clearly defining the risk factors of poor outcomes after surgery for CP. Therefore, we retrospectively analysed the results of the surgical treatment for CP at our institution to define the risk factors of poor outcomes.
A total of 97 patients (65 male, 67%) undergoing surgery for CP at our institution from 1995 to 2012 were included in this study. CP was diagnosed either preoperatively by cardiac catheterization or at surgery. The mean age was 60±12.5 years and the primary etiology was idiopathic in more than halt the cases, followed by prior cardiac surgery, post-irradiation, and miscellaneous. Preoperative and intraoperative risk factors for 30-day and late mortality were analyzed using stepwise multivariate logistic and Cox regression analysis respectively. Long-term survival was determined by the Kaplan-Meier curve. Mean follow-up was 2.9±3.8 years (range: 0.1-14 years).
All patients received either radical (53 patients, 55.2%) or partial (44 patients, 44.8%) pericardiectomy. Concomitant procedures were performed in 38 (39,2%) patients. Overall 30-day, 1-year and 5-year survival were 66.8 %, 58.1% and 52.6% respectively, without significant difference according to the underlying etiology. Univariate analysis showed that preoperative renal dysfunction, liver failure, respiratory insufficiency, emergency surgery and longer operating times were associated with significantly higher 30-day mortality. Multivariate analysis revealed patients with concomitant coronary artery disease to be at higher risk of poor immediate survival, whereas a higher glomerular filtration rate GFR (ml/min/1,73m2) was protective for early mortality. Long-term mortality was independently predicted by the presence of a coronary artery disease, a COPD (chronic obstructive pulmonary disease) and higher absolute creatinine value.
To conclude, surgery for constrictive pericarditis is associated with a relatively poor prognosis. Reduced left ventricular ejection fraction and right ventricular dilatation were independent predictors for early mortality, while coronary artery disease, chronic obstructive pulmonary disease, and renal insufficiency were risk factors for late mortality. Thus, indication for surgery needs to be determined on an individual basis and should be justified by an otherwise worse natural prognosis.:1 CONTENTS
