UNLABELLED The utility of (99m)Tc-tetrofosmin myocardial SPECT for assessment of pulmonary hypertension and right ventricular thickness has not been well studied. We hypothesized that a ratio of right ventricular activity to left ventricular activity (RV/LV uptake ratio) from SPECT myocardial perfusion images could identify the presence of increased right ventricular wall thickness and elevated...

Hydrotherapy (exercise in warm water) is considered to be a safe and beneficial method to use in the rehabilitation of stable heart failure patients, but there is little information on the effect of the increased venous return and enhanced preload in elderly patients with biventricular heart failure. We present a case of an elderly man who was recruited to participate in a hydrotherapy study. W...

BACKGROUND Postnatal outcome of fetuses with hypoplastic left heart syndrome (HLHS) is mainly determined by right ventricular function. In the present study we used spatio-temporal image correlation (STIC) to assess right ventricular function of fetuses with HLHS. METHODS Three-dimensional ultrasound with STIC technique was used to acquire heart images from fetuses that had HLHS and the norma...

background pulmonary arterial hypertension (pah) is a serious complication of unrepaired congenital left-to-right shunts. the final consequence is right ventricular (rv) systolic dysfunction and reversal of shunt. objectives the aim of this study was to evaluate the clinical course and paraclinical findings in a group of patients with pah associated with congenital heart disease (pah-chd). we a...

conclusions chronic smoking caused left ventricular diastolic dysfunction. acute intake caused left and right ventricular diastolic dysfunction. changes persisted up to 30 minutes after smoking, although diastolic blood pressure returned to normal state. objectives the current study aimed to evaluate the acute and chronic effects of smoking on the left and right ventricular (rv) diastolic funct...
