Pericardial decompression syndrome with acute right ventricular failure: a case series.

ABSTRACT:

Background

Pericardial decompression syndrome (PDS) is an uncommon complication of pericardial drainage of large pericardial effusions and cardiac tamponade characterized by paradoxical haemodynamic instability following drainage. Pericardial decompression syndrome may occur immediately, or in the days following pericardial decompression, and presents with signs and symptoms suggestive of uni-/biventricular failure or acute pulmonary oedema.

Case summary

This series describes two cases of this syndrome which demonstrates acute right ventricular failure as a mechanism of PDS and provides insights into the echocardiographic findings and clinical course of this poorly understood syndrome. Case 1 describes a patient who underwent pericardiocentesis, whilst Case 2 describes a patient who underwent surgical pericardiostomy. In both patients, acute right ventricular failure was observed following the release of tamponade and is favoured to be the cause of haemodynamic instability.

Discussion

Pericardial decompression syndrome is a poorly understood, likely underreported complication of pericardial drainage for cardiac tamponade associated with high morbidity and mortality. Whilst a number of hypotheses exist as to the aetiology of PDS, this case series supports haemodynamic compromise being secondary to left ventricular compression following acute right ventricular dilatation.

Project description:Aim The severity of cardiac impairment in acute heart failure (AHF) predicts outcome, but challenges remain to identify prognostically important non-invasive parameters of cardiac function. Left ventricular ejection fraction (LVEF) is relevant, but only in those with reduced LV systolic function. We aimed to assess the standard and advanced parameters of left and right ventricular (RV) function from echocardiography in predicting long-term outcomes in AHF. Methods A total of 418 consecutive AHF patients presenting over 12 months were prospectively recruited and underwent bedside echocardiography within 24 h of recruitment. We retrospectively assessed 8 RV and 5 LV echo parameters of the cardiac systolic function to predict 2-year mortality, using both guideline-directed and study-specific cutoffs, based on the maximum Youden indices via ROC analysis. For the RV, these were the tricuspid annular plane systolic excursion, RV fractional area change, tissue Doppler imaging (TDI) peak tricuspid annular systolic wave velocity, both peak- and end-systolic RV free wall global longitudinal strain (RV GLS) and strain rate (mean RV GLSR), RV ejection fraction (RVEF) derived from a 2D ellipsoid model and the ratio of the TAPSE to systolic pulmonary artery pressure (SPAP). For the LV, these were the LVEF, mitral regurgitant ΔP/Δt (MR dP/dt), the lateral mitral annular TDI peak systolic wave velocity, LV GLS, and the LV GLSR. Results A total of 7/8 parameters of RV systolic function were predictive of 2-year outcome, with study cutoffs like international guidelines. A cutoff of < −1.8 s–1 mean RV GLSR was associated with worse outcome compared to > −1.8 s–1 [HR 2.13 95% CI 1.33–3.40 (p = 0.002)]. TAPSE:SPAP of > 0.027 cm/mmHg (vs. < 0.027 cm/mmHg) predicted worse outcome [HR 2.12 95% CI 1.53–2.92 (p < 0.001)]. A 3-way comparison of 2-year mortality by LVEF from the European Society of Cardiology (ESC) guideline criteria of LVEF > 50, 41–49, and < 40% was not prognostic [38.6% vs. 30.9 vs. 43.9% (p = 0.10)]. Of the 5 parameters of LV systolic function, only an MR dP/dt cutoff of < 570 mmHg was predictive of adverse outcome [HR 1.63 95% CI 1.01–2.62 (p = 0.047)]. Conclusion With cutoffs broadly like the ESC guidelines, we identified RV dysfunction to be associated with adverse prognosis, whereas LVEF could not identify patients at risk.
