Palliative Procedures for Congenital Heart Disease: Imaging Findings and Complications.

Palliative procedures are performed for congenital heart diseases that are not amenable for definitive surgical procedures or as a component of hybrid procedures along with transcatheter interventions. Multimodality imaging plays an important role in the follow-up of these palliative procedures, mainly for the timely detection of complications and for planning any subsequent palliative or definitive procedure. Echocardiography is the first-line imaging modality, with CT and MRI used as complementary techniques in indeterminate cases.

Effectiveness of the First Trimester Samrakshan Protocol for the Identification of Pregnant Women at High Risk for Preterm Pre-eclampsia.

 To determine the effectiveness of the first trimester Samrakshan protocol for the identification of pregnant women at high risk for preterm pre-eclampsia (PE).  Samrakshan uses a protocol that integrates routine first-trimester ultrasound assessment at 11 to 14 gestation weeks with the measurement of mean arterial blood pressure and mean uterine artery pulsatility index assessment to determine a customized risk for preterm PE and fetal growth restriction. Based on the risk assessment, pregnant women are classified as high or low risk.

Oral Solid Dosage form Modification in Community Pharmacies of Kavrepalanchok and Bhaktapur Districts of Nepal.

Background People may modify their oral solid dosage form of medicine to deal with problem faced during medicine administration. The modification of dosage form may adversely affect the quality, safety and efficacy of the medicine. Objective To investigate the causes and practices of oral solid dosage form modification among the consumers going to community pharmacies.

Analyzing Transfer Learning of Vision Transformers for Interpreting Chest Radiography.

Limited availability of medical imaging datasets is a vital limitation when using "data hungry" deep learning to gain performance improvements. Dealing with the issue, transfer learning has become a de facto standard, where a pre-trained convolution neural network (CNN), typically on natural images (e.g.

Myocardial Strain Evaluation with Cardiovascular MRI: Physics, Principles, and Clinical Applications.

Myocardial strain is a measure of myocardial deformation, which is a more sensitive imaging biomarker of myocardial disease than the commonly used ventricular ejection fraction. Although myocardial strain is commonly evaluated by using speckle-tracking echocardiography, cardiovascular MRI (CMR) is increasingly performed for this purpose. The most common CMR technique is feature tracking (FT), which involves postprocessing of routinely acquired cine MR images.

A case report of cerebral venous infarction due to venous sinus thrombosis as complication in a Covid-19 patient.

Coronavirus disease of 2019 (COVID-19) is a pandemic disease caused by a new corona virus known as SARS-CoV-2 (severe acute respiratory syndrome-coronavirus-2) and well known to increase the risk of developing venous thromboembolism; thus, patients with COVID-19 may present with neurological disorders. Venous thromboembolism is an important cause of morbidity and mortality in patients with COVID-19. We report a case of 35 years old woman who presented neurological disorders due to venous infarction and venous sinus thrombosis as complication in COVID-19.

Imaging Features of Complications after Coronary Interventions and Surgical Procedures.

Coronary artery interventions and surgical procedures are used in the treatment of coronary artery disease and some congenital heart diseases. Cardiac and noncardiac complications can occur at variable times after these procedures, with the clinical presentation ranging from asymptomatic to devastating symptoms. Invasive coronary angiography is the reference standard modality used in the evaluation of coronary arteries, with intravascular US and optical coherence tomography providing high-resolution information regarding the vessel wall.

Bands in the Heart: Multimodality Imaging Review.

Multiple bands and bandlike structures can be found within the cardiac chambers, which can be evaluated with various imaging modalities including echocardiography, CT, MRI, and invasive angiography. These bands can be classified as normal structures or normal variants, aberrant structures, or pathologic entities. Normal structures include the crista terminalis, taenia sagittalis, Chiari network, coumadin ridge, moderator band, papillary muscles, and chordae tendineae.

Multimodality Imaging of Complications of Cardiac Valve Surgeries.

Replacement with a prosthetic heart valve (PHV) remains the definitive surgical procedure for management of severe cardiac valve disease. PHV dysfunction is uncommon but can be a life-threatening condition. The broad hemodynamic and pathophysiologic manifestations of PHV dysfunction are stenosis, regurgitation, and a stuck leaflet.

Imaging of pulmonary hypertension: an update.

Pulmonary hypertension (PH) is characterized by elevated pulmonary arterial pressure caused by a broad spectrum of congenital and acquired disease processes, which are currently divided into five groups based on the 2013 WHO classification. Imaging plays an important role in the evaluation and management of PH, including diagnosis, establishing etiology, quantification, prognostication and assessment of response to therapy. Multiple imaging modalities are available, including radiographs, computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine, echocardiography and invasive catheter angiography (ICA), each with their own advantages and disadvantages.
