Ventricular dysfunction, elevated pulmonary vascular resistance, and residual distal pulmonary artery distortion contribute to early mortality after a Fontan operation; they may be transient ... | C14 |
4,095 | 3,194 | Does blood rheology revert to normal after myocardial infarction?
After myocardial infarction there is an acute deterioration of the flow properties of blood.
The present study was designed to test whether the abnormality persists.
Blood and plasma viscosity, red cell aggregation and deformability, haematocrit, eryt... | C14 |
4,096 | 9,154 | Comparison of thallium-201 and technetium-99m hexakis 2-methoxyisobutyl isonitrile single-photon emission computed tomography for estimating the extent of myocardial ischemia and infarction in coronary artery disease.
Single-photon emission computed tomography (SPECT) using thallium-201 (Tl-201) was compared with tech... | C14 |
4,097 | 2,305 | Effects of bepridil and diltiazem on ventricular repolarization in angina pectoris.
To examine the time-course and potential predictors of prolongation of ventricular repolarization with the calcium antagonist bepridil, the effects of bepridil (300 to 500 mg/day; n = 45) and diltiazem (180 to 300 mg/day; n = 42) on QT... | C14 |
4,098 | 6,869 | Combined repair of transposed great arteries and total anomalous pulmonary venous connection.
We report an unusual association of transposition of the great arteries and total anomalous pulmonary venous connection in the right atrium that was successfully repaired by a modified Mustard procedure. | C14 |
4,099 | 2,306 | Effects of intravenous verapamil on left ventricular relaxation and filling in stable angina pectoris.
Left ventricular (LV) diastolic function is often impaired in coronary artery disease (CAD).
To assess whether verapamil could improve LV diastolic properties, 12 patients with CAD undergoing right- and left-sided c... | C14 |
