Constrictive pericarditis in the twenty-first century: An old disease revisited

Table 1 Sensitivity, specificity, positive predictive value and negative predictive value of echocardiographic parameters of Mayo Clinic Criteria for the diagnosis of constrictive pericarditis

Echocardiographic parameter	Sensitivity	Specificity	PPV	NPV
Respirophasic ventricular septal motion	94%	73%	93%	77%
MV e’ medial > 8 cm/second	81%	91%	97%	58%
Annulus reversus	71%	79%	93%	45%
Diastolic hepatic vein expiratory reversal/forward flow velocity ≥ 0.8	73%	66%	86%	42%
Respirophasic ventricular septal motion + MV e’ medial > 8 cm/second	80%	96%	99%	58%
Respirophasic ventricular septal motion + MV e’ medial > 8 cm/second + diastolic hepatic vein expiratory reversal/forward flow velocity ≥ 0.8	67%	99%	100%	50%

PPV: Positive predictive value; NPV: Negative predictive value; MV: Mitral valve.
