Abstract:
Objective To investigate the characteristics and the diagnostic value of the tissue strain imaging in constrictive pericarditis(CP).Methods Twenty-six patients and thirty controls underwent comprehensive echocardiography with apical four chamber tissue Doppler imaging and strain imaging.Peak strain of the middle segments of the inter-ventricle septum and left ventricular lateral wall was recorded.The peak strain difference and strain ratio between the two segments were calculated.Results In patients with CP peak strain of the left ventricle lateral wall was significantly lower than that of the septum[(-5.60?3.46)% vs(-14.14?4.11)%,P
