conclusions in the case of existence gaussian noise, the results confirm that denoising is not effective on the measurement of t2* value. in the case of image distortion by rician noise, a predictor model is proposed to estimate the original t2* value. the predictor model is used to estimate the t2* value of new patients. the predicted t2* values were in good agreement with the corresponding or...

A 56-year-old woman was urgently admitted following an episode of syncope. Fourteen years earlier, she had undergone implantation of a tricuspid prosthesis due to Ebstein anomaly, with congestive heart failure (NYHA class III) and severe tricuspid regurgitation. A mechanical prosthesis had been selected (31-mm Medtronic-Hall® valve; Medtronic Inc., Minneapolis, Minnesota, USA) because of its st...

A two-dimensional echocardiographic manifestation of a ruptured right sinus of Valsalva aneurysm is described in this case report. The ultrasono-cardiotomograms demonstrated the aneurysm cut longitudinally and protruding into the outflow tract of the right ventricle. The configuration of the aneurysm was consistent with the contrast medium-filled sinus demonstrated by angiocardiography. In syst...

Critical congenital pulmonary stenosis with intact interventricular septum is a cyanotic and potentially lethal neonatal cardiac anomaly. Percutaneous transcatheter balloon valvuloplasty for critical often presents technical difficulties due to supra-systemic pressure in right ventricle. Using transjugular approach instead of the femoral vein helps dealing this issue. We describe successful use...

Usefulness of two-dimensional and Doppler echocardiography in diagnosis of the ruptured interventricular septum in a course of myocardial infarction was evaluated basing on own material consisted of 6 cases. Ventricular septal defect was visualized in 5 patients. The blood flow through the ventricular septum was detected in all of 6 patients. Obtained results were concordant with intraoperative...

Trauma to the chest may result in rupture of the interventricular septum (Cary, Hurst, and Arentzen, 1958). Disturbances of conduction, including complete heart block, may follow (Dolara, 1964), or they may arise in the presence of an intact septum (Levine, Roberts, and Morrow, 1962). In the case to be reported, non-penetrating trauma produced structural cardiac damage, associated with the deve...

A case is reported of left anterior hemiblock and right bundle-branch block produced by a hydatid cyst of the interventricular septum. The electrocardiographic changes are attributed to the great distortion produced by the cystic mass in the septum, with elongation of the right and left anterior bundles. The depth of the S waves in leads II, III, and aVF is in close relation with the degree of ...

Features of longitudinal left ventricular (LV) myocardial deformation in female patients reproductive age with undifferentiated connective tissue dysplasia (UCTD) have not been specifically studied before. Aim. To study the features LV using speckle tracking echocardiography UCTD. Material and Methods. A noninvasive assessment systolic direction was performed 20 young adult UCTD (the average 23...

Subendocardial hydatid . cysts may rupture into the right or left chamber of the heart to produce pulmonary or systemic embolisation.' Few cases have been reported,2 and I believe that this case is the first to be reported in the United Kingdom in which a primary hydatid cyst in the interventricular septum caused multiple emboli in the pulmonary and systemic arterial circulation. The electrocar...

A 30-year-old asymptomatic man with chronic hepatitis B was evaluated for an incidentally visualized intracardiac mass on abdominal ultrasonography. Two-dimensional (2D) transthoracic echocardiography (TTE) revealed a structurally normal heart except for the presence of homogeneously echodense, round, mobile mass (2.0×2.8 cm) within the left ventricular cavity (Fig. 1a, Video 1a). No flow abnor...
