Isolated rupture of the right ventricle in a patient with acute inferior wall MI.

A case of isolated rupture of the right ventricle secondary to acute MI, presented as cardiac tamponade, is reported. The patient underwent successful emergency surgery for closure of the right ventricular rupture without aortocoronary bypass.

Prognostic implications of rest and exercise radionuclide ventriculography in patients with suspected or proven coronary heart disease.

Rest and exercise radionuclide ventriculography were assessed for their value in predicting major cardiac events in patients with chest pain. Of 219 patients who were followed for up to 51 months, 42 had major cardiac events: 12 patients (5.5%) died, 5 (2.

Resting kinetics of thallium-201 in patients with coronary artery disease.

The thallium washout was analyzed in 40 patients with angiographically documented CAD, using circumferential time-activity profiles of the initial and four-hour delayed images. A net washout pattern (fewer counts in delayed images than initial images) was observed in the distribution of normal and diseased vessels. A negative washout (wash-in) (a net increase in counts in the four-hour delayed images) was observed only in the presence of diseased vessels, even if the initial scans were normal.

Calcification of the tricuspid anulus diagnosed by two-dimensional echocardiography.

An 84-year-old female who previously underwent repair of an atrial septal defect had evidence of increased reflectiveness of the posterior tricuspid anulus in the apical four-chamber view and the right ventricular two-chamber view. In addition, the inferior vena cava was dilated and during contrast echocardiography, contrast echoes appeared during systole suggesting tricuspid regurgitation. Tricuspid annular calcification was confirmed by fluoroscopic examination.
