Functional echocardiography (fECHO) refers to a bedside, limited assessment of the ductus arteriosus, myocardial performance and pulmonary or systemic haemodynamics that is brief in nature and addresses a specific clinical question or management dilemma. This point-of-care ultrasonography is increasingly used internationally and locally among neonatal units to assist with management of neonatal...

Kowalski and Abelmann originally described the hyperdynamic circulation associated with cirrhosis in 1953, which is characterised by an increased cardiac output, heart rate, and stroke volume and reduced peripheral vascular resistance [1]. The hyperdynamic circulation of cirrhosis is characterised by increased cardiac output and decreased systemic vascular resistance being independently associa...

Haemodynamics, and in particular wall shear stress, is thought to play a critical role in the progression and rupture of intracranial aneurysms. A novel method is presented that combines image-based wall motion estimation obtained through non-rigid registration with computational fluid dynamics (CFD) simulations in order to provide realistic intra-aneurysmal flow patterns and understand the eff...

AIM To investigate the effect of retrobulbar and subconjunctival anaesthesia on retrobulbar haemodynamics by colour Doppler imaging. METHOD 39 patients (mean age 71 (SD 9) years; 19 females, 20 males) undergoing planned cataract surgery were included in the prospective study. Colour Doppler imaging (Siemens Sonoline Sienna, Germany) was performed before, directly after either subconjunctival ...
