Interatrial septum in subcostal view

In an earlier post it was shown that false echo dropouts can occur in the interatrial septum as the ultrasound beam is parallel to the structure being imaged. It was also mentioned that subcostal view is best for imaging the interatrial septum. This picture in subcostal view gives an excellent image of the interatrial septum (IAS) between the right atrium (RA) above and the left atrium (LA) below. LV: Left ventricle. Most echocardiographers use this orientation for subcostal view, though it is anatomically an inverted view as the transducer is kept below the structures being imaged. On the contrary, most paediatric echocardiographers invert the image in the machine while imaging from the subcostal view in order to get a more straight forward anatomical oriented of structures being imaged. Colour Doppler imaging of interatrial flow across and atrial septal defect or patent foramen ovale is also good in this view as the principle of Doppler is that the imaging is better when the flow being imaged is parallel to the ultrasound beam. Left to right flow will be seen as red and reversal of shunt will be shown as blue, in this view. Gradient across the defect in IAS is also accurately measured by this approach. The gradient will be significant in restrictive defects while it will be negligible in a large defect. Reverse flow across the IAS in the absence of features of pulmonary hypertension should alert us to the possibility of total anomalous pulmonary venous drainage. This w...

Authors: Bergland OU, Søraas CL, Larstorp ACK, Halvorsen LV, Hjørnholm U, Hoffman P, Høieggen A, Fadl Elmula FEM Abstract PURPOSE: The blood pressure (BP) lowering effect of renal sympathetic denervation (RDN) in treatment-resistant hypertension shows variation amongst the existing randomised studies. The long-term efficacy and safety of RDN require further investigation. For the first time, we report BP changes and safety up to 7 years after RDN, compared to drug adjustment in the randomised Oslo RDN study. MATERIALS AND METHODS: Patients with treatment-resistant hypertension, defined...

Authors: Zhang W, Xu JZ, Lu XH, Li H, Wang D, Wang JG Abstract PURPOSE: We hypothesise that dietary sodium intake interacts with serum uric acid to influence blood pressure (BP) in children and adolescents. In the present study, we investigated ambulatory BP in relation to hyperuricaemia, dietary sodium intake and their interaction in children and adolescents with hypertension. MATERIALS AND METHODS:  A total of 616 study participants were 10-24 years old and had primary hypertension diagnosed after admission in a specialised inpatient ward. Ambulatory BP monitoring was performed during hospitalisat...

Conclusion: Ambulatory renal and cardio-vascular follow-up in case of neonatal medical history can be enhanced, with necessity to raise awareness and to edict guidelines available to pediatricians.What is Known:•There is a compelling evidence of long-term renal and cardiovascular consequences of prematurity and low birth weight.•Specific cardiovascular and renal follow-up guidelines, coming from professional organizations, are currently not available for these patients.What is New:•Pediatricians in ambulatory setting do not adapt their renal and cardiovascular follow-up in case of neonatal medical history.&b...
