Atrial septal defect (ASD)

Illustrated Review with ECG, CXR, Echo Video, Cath Images X-ray chest in atrial septal defect X-ray chest PA view in atrial septal defect with pulmonary hypertension (Click on the image for an enlarged view) The main pulmonary artery (MPA) is grossly dilated. The right pulmonary artery (RPA) is also quite enlarged. Right atrial enlargement is seen as a shift of the cardiac contour to the right of the spine. Pulmonary vascularity is increased and prominent end on vessels (End on) are also seen. Apex is upwards, suggesting a right ventricular configuration. All features suggest a large secundum atrial septal defect with a large left to right shunt producing severe pulmonary hypertension. Cardiomegaly on chest x-ray is suggestive of atrial septal defect in Eisenmenger syndrome, while it is unlikely in ventricular septal defect and patent ductus arteriosus. Cardiomegaly is mainly due to the grossly dilated right atrium in atrial septal defect. The right atrium is not enlarged in the other two varieties of Eisenmenger syndrome. In ventricular septal defect with large left to right shunt, the cardiac size comes down as pulmonary hypertension develops and the shunt decreases. Cardiomegaly in ventricular septal defect and patent ductus arteriosus with large left to right shunt are due to left ventricular enlargement. But this comes down with the development of pulmonary hypertension. That is why cardiomegaly is not a feature of Eisenmenger syndrome due to ventricular septal defect a...

Petrov, Vladimir V. Petrov, Timofei S. Zatsepin, Gleb B. Sukhorukov, Dmitry A. GorinAbstractHigh intensity focused ultrasound (HIFU) is widely used in medical practice, including cancer therapy. Also this approach is promising for remote release of encapsulated drugs in various other biomedical applications where local treatment is needed. Our approach underpins the minimization of HIFU impact on possible degradation of biological t...

ConclusionAcute organophosphate poisoning treated with atropine showed a potential for inducing prothrombotic coagulation abnormalities, presented with PT. This life-threatening complication may additionally contribute to prolonged morbidity and mortality in OP poisonings, especially in patients with medical history of comorbidites.

DNA tests might identify ‘invisible population’ who are not currently seen as in dangerHundreds of thousands more adults in the UK could benefit from taking statins because their genes put them at high risk of heart disease, research suggests.Speaking on Wednesday at the UK Biobank conference in London, Prof Sir Peter Donnelly, the founder of the company Genomics Plc, warned of an “invisible population” who are not identified as at risk by current screening programmes because their blood pressure and cholesterol do not raise red flags.Continue reading...

A 71-year-old with Stanford type B aortic dissection treated with Cook Medical (Bloomington, IN) ProForm ™ stent grafts 3 years previously was referred to the nephrology outpatient clinic for asymptomatic new-onset renal impairment. Other comorbidities were chronic hepatitis B, diabetes mellitus, and hypertension. Clinic blood pressure was 152/80 mm Hg, but physical examination was otherwise unremar kable. Serum creatinine was 142 μmol/l, urine protein-to-creatinine ratio 4.07 g/g, and glomerular hematuria was present (210 red cells) without pyuria on urine microscopy.

The role of the terminal complement pathway as the cause of atypical hemolytic uremic syndrome (aHUS) is widely recognized, but the relative contribution of the effectors C5a/C5aR1 and C5b-9 to disease pathogenesis has not been defined. Using FHR/R mice carrying a factor H mutation that causes cell surface complement alternative pathway dysregulation, Ueda documented that in FHR/R mice, C5b-9 causes renal thrombotic microangiopathy (TMA) whereas C5a/C5aR drives macrovascular thrombosis. This commentary addresses the implications and limitations of this study.

The hypothesis that prenatal exposure to poor maternal health or nutrition is a risk factor for adult-onset disease was first proposed by the epidemiologist David Barker in 1990, based on observations in a cohort of low birth weight infants followed into adulthood. Fetal programming is now accepted as an important contributor to the development of cardiovascular disease and other adult conditions. Although the mechanisms remain unknown, it is increasingly assumed that epigenetic mechanisms play a key role in fetal programming.
