ABSTRACT
BACKGROUND:
With this study, we sought to investigate the prognostic value of echocardiographic tissue imaging markers in predicting tamponade among patients with large malignant pericardial effusion compared to routinely used echocardiographic signs.METHODS:
A total of 96 consecutive patients with large malignant pericardial effusion, not in clinical cardiac tamponade, underwent an echocardiographic examination and were prospectively assessed for 1 month. Clinically evident cardiac tamponade was considered as the study endpoint. The prognostic performance of tricuspid valve annular plane systolic excursion (TAPSE) and peak systolic annular velocity at the lateral margin of the tricuspid valve annulus (STV ) was assessed and compared to routinely used imaging signs.RESULTS:
During follow-up, 37 patients (39%) developed clinically evident cardiac tamponade. TAPSE (area under the curve [AUC] 0.958) and STV (AUC 0.948) had excellent predictive accuracy for tamponade. Multivariate analysis showed that TAPSE (Hazard ratio [HR] 3.03; 95% CI 1.60-5.73, P=.001) and STV (HR 1.17; 95% CI 1.05-1.29, P=.005) remained independent significant predictors of cardiac tamponade. Reclassification analysis and decision curve analysis showed additive prognostic value and adjunct clinical benefit of these markers when added to a recently published triage pericardiocentesis score.CONCLUSION:
Echocardiographic tissue imaging markers such as TAPSE and STV are characterized by an excellent prognostic ability for development of cardiac tamponade and better prognostic value compared to routine echocardiographic signs in patients with large malignant pericardial effusion. Incorporating these markers to a recent triage pericardiocentesis score resulted in additional prognostic value and increased clinical benefit.Palavras-chave
