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...

CONCLUSION: Inpatient consultations is very useful to the patient and managing physician. Although a better knowledge in the identification of common ophthalmic conditions can help to reduce the number of inpatient consults from other medical specialties. PMID: 32476114 [PubMed - in process]

Conclusion: Sarcoidosis cannot be reliably differentiated from tuberculosis based on cytomorphology alone. A combination of clinical features, endosonography, cytology and microbiology is required for accurate diagnosis. PMID: 32476956 [PubMed - in process]

Conclusions: Patients with granulomatosis with polyangiitis in first years after diagnosis have higher risk of venous thromboembolism than coronary artery disease. This finding is probably related to hypercoagulability induced by the disease and its therapy. PMID: 32476955 [PubMed - in process]

Today in the Metro Detroit area it was announced that Beaumont Health - one of the largest health care system in the Detroit area was turning toward Northstar for it's anesthesia services. Attached is the letter from Beaumont's CEO. NAPA recently acquired Mednax's American Anesthesia division which has the physician contract at Beaumont's other main hospitals in the area. I imagine that Beaumont will ask NAPA to take on the CRNAs or risk losing it all to NorthStar. I do not work for this... Northstar and NAPA in SE Michigan

There's no evidence that a daily aspirin should be taken by most adults in good cardiovascular health, according to a new review. The risk of a major bleeding event due to the drug's blood thinning effects outweighs the benefit, the research said.

There has been no shortage of innovation and collaboration across the industry to provide critical medical solutions in response to the coronavirus pandemic, but developing a much-needed device is only half the battle. To truly make an impact, innovators need to make their technology available to as many patients as possible. With that end-goal in mind, some organizations are open-sourcing their designs in an effort to ramp up production and distribution. The latest example of this trend comes out of the University of Minnesota (UMN) Bakken Medical Device Center. In early April, MD+DI reported that ...

Authors: Ronconi G, Teté G, Kritas SK, Gallenga CE, Caraffa A, Ross R, Conti P Abstract Acute severe respiratory syndrome coronavirus-2 (SARS-CoV-2) caused a global pandemic coronavirus disease 2019 (COVID-19). In humans, SARS-CoV-2 infection leads to acute respiratory distress syndrome which presents edema, hemorrhage, intra-alveolar fibrin deposition, and vascular changes characterized by thrombus formation, micro-angiopathy and thrombosis. These clinical signs are mediated by pro-inflammatory cytokines. In recent studies it has been noted that COVID-19 pandemic can affect patients of all ages, including c...

Authors: Yang SM, Yi DY, Choi GJ, Lim IS, Chae SA, Yun SW, Lee NM, Kim SY, Choi ES Abstract BACKGROUND: Endoscopy is used for diagnosing and treating various digestive diseases in children as well as in adults. However, in pediatric patients, it is recommended that sufficient sedation should be ensured before conducting endoscopy, since insufficient sedation may cause serious complications. However, in Korea, no studies have yet described the types of sedation drugs, effects of sedation, and efficiency of endoscopy with respect to the sedation instructor. Thus, we investigated the effectiveness of sedative procedur...
