Diagnosis and surgical management of pericardial constriction after cardiac surgery. | LitMetric

AI Article Synopsis

Article Abstract

Objectives: Previous cardiac surgery is an increasingly common etiology of constrictive pericarditis, but there is a paucity of data on clinical presentation and outcome of surgical treatment.

Methods: We reviewed data of 263 patients who underwent pericardiectomy for postoperative constriction from January 1, 1993, through July 1, 2017. Outcomes of interest were early and late mortality, as well as features of clinical presentation.

Results: Median patient age was 64 (56-72) years, and the median interval between previous operation and pericardiectomy was 2.7 years (range, 0-54 years). Previous operations included coronary artery bypass grafting in 114 (43%), valve surgery in 85 (32%), combined coronary artery bypass grafting and valve surgery in 33 (13%), and other procedures in 31 (12%). Common presentations were symptoms of right heart failure in 221 (84%) or dyspnea in 42 (16%). Moderate-to-severe tricuspid valve regurgitation was present in 108 (41%) patients. There were 14 (5.5%) deaths within 30 days postoperatively, and survival at 5 and 10 years postoperatively was 61% and 44%. On multivariate analysis, older age (P = .013), diabetes (P = .019), and nonelective pericardiectomy within 2 years of cardiac surgery (P < .001) were associated with decreased long-term survival.

Conclusions: Pericardial constriction after cardiac surgery can present at any interval postoperatively. Symptoms and signs of right heart failure in patients with previous cardiac surgery should alert physicians to the possibility of pericardial constriction followed by a correct diagnosis. Pericardiectomy performed urgently following cardiac operation has poor long-term outcomes.
