Abnormal diastolic and systolic septal motion following pericardiectomy demonstrated by ciné DENSE MRI
نویسندگان
چکیده
Constrictive pericarditis can lead to paradoxical interventricular septal motion. Displacement encoding with stimulated echoes (DENSE) magnetic resonance imaging (MRI) provides a method for quantifying myocardial motion and strain. A case of constrictive pericarditis is presented and the diastolic 'septal bounce' is clearly evident in both anatomical and DENSE ciné MRI images. (See video link to full-text electronic article). The postoperative systolic septal wall-motion abnormality of cardiac surgery is portrayed with greater precision by DENSE than anatomical ciné MRI images.

Cross sectional echocardiographic demonstration of the mechanisms of abnormal interventricular septal motion in congenital total absence of the left pericardium.
OBJECTIVE To investigate the influence of the absence of the pericardium on the left ventricular wall, particularly on interventricular septal motion, using M mode and cross sectional short axis echocardiography in patients with congenital total absence of the left pericardium. METHODS 21 patients with, congenital total absence of the left pericardium were divided into three groups according ...

OBJECTIVES The study assessed changes in left ventricular systolic and diastolic function after pericardiectomy in patients with constrictive pericarditis and correlated postoperative Doppler echocardiographic findings with clinical status. BACKGROUND Despite the efficacy of pericardiectomy, some patients with constrictive pericarditis fail to improve postoperatively. Data on serial evaluatio...

The echocardiographic appearances of the mitral valve after reconstructive surgery for non-rheumatic mitral regurgitation have been studied. Twenty-two patients, divided into 3 groups, were studied. In group 1 there were 12 patients with ruptured chordae tendineae and/or anterior mitral leaflet perforation, who underwent chordal reattachment and plication of leaflets or commissures. After opera...
