Acute Right Ventricular Dysfunction in Intensive Care Unit

Table 1

Acute right ventricular dysfunction definition.

Echo parameters		ECG signs	Biomarkers
RV systolic function	RV dilation
TAPSE < 16 mm	ED RVD/LVD ratio > 0.9	Complete RBBB	BNP > 100 pg/mL
S < 10 cm/sec	ED RVA/LVA ratio > 0.6	Incomplete RBBB	NT-proBNP > 900 pg/mL
RV fractional area change < 35%	ED RVD > 42 mm (at the base)	Anteroseptal ST elevation
RV ejection fraction < 45%	ED RVD > 33 mm (at the middle third of RV)	Anteroseptal ST depression
	Septal dyskinesia in the RV focused view	Anteroseptal T-wave inversion

BNP: B-type natriuretic peptide; ED RVD/LVD ratio: end-diastolic RV diameter/LV diameter ratio; ED RVA/LVA ratio: end-diastolic RV area/LV area ratio; ED RVD: end-diastole RV diameter; NT-proBNP: N-terminal pro-BNP; S: pulsed Doppler S wave; TAPSE: tricuspid annular plane systolic excursion. At least one of the items must be present (echo parameters, ECG signs, and biomarkers) [30].
