Association between pregnancy and long-term cardiac outcomes in women with congenital heart disease.

Am J Obstet Gynecol 2021 Jul 28. Epub 2021 Jul 28.

University of Utah Health, Salt Lake City, UT; Intermountain Healthcare, Salt Lake City, UT.

Background: As early life interventions for congenital heart disease (CHD) improve, more patients are living to adulthood and considering pregnancy. Scoring and classification systems predict maternal cardiovascular risk of pregnancy in the context of congenital heart disease but these scoring systems do not assess the potential subsequent risks following pregnancy. Data on long-term cardiac outcomes after pregnancy are unknown for most lesion types. Read More

Ventral calcification in the common femoral artery: A risk factor for major transcatheter aortic valve intervention access site complications.

Catheter Cardiovasc Interv 2021 Jul 31. Epub 2021 Jul 31.

Department of Cardiology and Angiology I, University Hospital Freiburg and Faculty of Medicine, University of Freiburg, Freiburg, Germany.

Background: Transfemoral TAVI has become the treatment of choice for severe aortic stenosis in elderly patients, especially with increased perioperative risk. Frailty, however, favors complications at the vascular access site due to the large bore vascular sheath devices necessary for valve deployment. Read More

Endoscopic Evaluation and Management of Late Complications After Bariatric Surgery: a Narrative Review.

Obes Surg 2021 Jul 30. Epub 2021 Jul 30.

The Center for the Treatment of Obesity and Diabetes, Hospital Oswaldo Cruz, Sao Paulo, Brazil.

Despite ongoing evolution in technique and a low mortality rate, clinicians may care for patients who suffer late complications (> 90 days of surgery) after bariatric surgery. Endoscopic techniques are used to identify and manage many of the late complications of the two most commonly performed bariatric surgeries: sleeve gastrectomy and Roux-en-Y gastric bypass. Stenosis at the incisura angularis and gastroesophageal reflux disease may occur in patients who have undergone a sleeve gastrectomy. Read More

Angiology 2021 Jul 30:33197211034286. Epub 2021 Jul 30.

Key Laboratory of Cardiovascular Proteomics of Shandong Province, Department of Geriatric Medicine, Qilu Hospital of Shandong University, Jinan, China.

Circulating levels of microRNA-221 and 222 (miR-221/222) in patients with coronary artery disease (CAD) are elevated, yet the relationship between circulating miR-221/222 and the severity of coronary lesions in patients with acute coronary syndrome (ACS) remains unknown. In this study, the relative expression levels of circulating miR-221/222 in patients with ACS (n = 267) and controls (n = 71) were compared by real-time fluorescence quantitative-polymerase chain reaction (RT-qPCR). The ACS group was further divided into unstable angina pectoris (UA) group (n = 191) and acute myocardial infarction (AMI) group (n = 76). Read More

Idiopathic pyometra in a postmenopausal patient.

Clin Imaging 2021 Jul 26;80:145-147. Epub 2021 Jul 26.

Department of Radiology, St. Joseph Mercy Oakland Hospital, Pontiac, MI, United States; Huron Valley Radiology, Ypsilanti, MI, United States.

Pyometra is a rare gynecological condition most commonly seen in elderly, postmenopausal women. Malignancy should always be considered as the primary etiology until proven otherwise in the investigation of an intrauterine infection. Clinical signs and symptoms can be vague or nonexistent, and thorough investigation with ultrasound and cross-sectional imaging may be necessary to understand the extent of the disease and best course of treatment.

Angiography-based estimation of coronary physiology: A frame is worth a thousand words.

Trends Cardiovasc Med 2021 Jul 27. Epub 2021 Jul 27.

First Department of Cardiology, National and Kapodistrian University of Athens, Medical School, Hippokration Hospital, Athens, Greece.

Cumulative evidence has shown that coronary revascularization should be guided by functional significance of coronary lesions. Fractional flow reserve (FFR) is the gold standard for assessment of hemodynamic significance of coronary stenosis and FFR-guided percutaneous coronary intervention has improved clinical outcomes in patients with coronary artery disease. However, limitations of FFR such as increased operational time and cost, requirement of pressure wire and adenosine and technical difficulties have led to significant underutilization of the method in clinical practice.

The Renal Vasculature: What the Radiologist Needs to Know.

Radiographics 2021 Jul 30:200174. Epub 2021 Jul 30.

From the Joint Department of Medical Imaging, University Health Network, Mount Sinai Hospital, and Women's College Hospital, University of Toronto, 200 Elizabeth St, Toronto, ON, Canada M5G 2C4 (A.L., M.J.T., K.K., S.K.); Department of Radiology, University of Iowa, Iowa City, Iowa (S.N.); and Department of Medical Imaging, Ottawa Hospital, University of Ottawa, Ottawa, Ont, Canada (N.S.).

The physiologic role of the kidneys is dependent on the normal structure and functioning of the renal vasculature. Knowledge and understanding of the embryologic basis of the renal vasculature are necessary for the radiologist. Common anatomic variants involving the renal artery (supernumerary arteries and prehilar branching) and renal vein (supernumerary veins, delayed venous confluence, retroaortic or circumaortic vein) may affect procedures like renal transplantation, percutaneous biopsy, and aortic aneurysm repair.

Roadmap Consensus on Carotid Artery Plaque Imaging and Impact on Therapy Strategies and Guidelines: An International, Multispecialty, Expert Review and Position Statement.

AJNR Am J Neuroradiol 2021 Jul 29. Epub 2021 Jul 29.

Surgery (T.H.), University of Washington, Seattle, Washington.

Current guidelines for primary and secondary prevention of stroke in patients with carotid atherosclerosis are based on the quantification of the degree of stenosis and symptom status. Recent publications have demonstrated that plaque morphology and composition, independent of the degree of stenosis, are important in the risk stratification of carotid atherosclerotic disease. This finding raises the question as to whether current guidelines are adequate or if they should be updated with new evidence, including imaging for plaque phenotyping, risk stratification, and clinical decision-making in addition to the degree of stenosis.

Is fetuin-A a biomarker of dialysis access dysfunction?

J Vasc Access 2021 Jul 29:11297298211035846. Epub 2021 Jul 29.

Department of Nephrology, Hospital de Mollet, Fundació Sanitària Mollet, Mollet del Vallès, Barcelona, Spain.

Background: The arteriovenous (AV) access function of hemodialysis (HD) patients can be impaired by afferent artery stiffness due to preexisting microcalcification and by venous stenosis secondary to neointimal hyperplasia in whose development participates an upregulated local inflammatory process. Fetuin-A is a circulating potent inhibitor of vascular calcification and plays an important anti-inflammatory role. The aims of this prospective study were to investigate the relationship between baseline serum fetuin-A levels and: blood flow (Q) values at baseline, AV access failure (thrombosis or intervention for stenosis) during follow-up and primary unassisted AV access patency.
