Coronary microvascular dysfunction in patients undergoing transcatheter aortic valve implantation

Heart BMJ

Objectives This study aimed to evaluate the prognostic value of coronary microvascular dysfunction (CMD) at long term after transcatheter aortic valve implantation (TAVI) and to explore its relationship with extravalvular cardiac damage (EVCD). CMD was defined as IMR angio ≥30 units. CMD was defined as IMR angio ≥30 units.

Right Heart Catheterization in Tetralogy of Fallot

All About Cardiovascular System and Disorders

Right Heart Catheterization in Tetralogy of Fallot With the availability of high resolution echocardiographic images and Doppler echocardiography, role of cardiac catheterization has come down in tetralogy of Fallot and other congenital heart diseases in general. Normal subjects have a value around 2.1.

Norwood Procedure for Hypoplastic Left Heart Syndrome

All About Cardiovascular System and Disorders

Transcript of video: Hypoplastic Left Heart Syndrome is a very severe form of congenital heart disease, in which, the left ventricle, aorta and mitral and aortic valves are hypoplastic and valves may be atretic as well. This is diagrammatic representation of hypoplastic left heart syndrome.

Surgical Treatment of Tetralogy of Fallot and Sequelae

All About Cardiovascular System and Disorders

Transcript of video: Tetralogy of Fallot is one of the commonest cyanotic congenital heart diseases. One is ventricular septal defect, second is overriding aorta, third is pulmonary stenosis, usually right ventricular outflow tract stenosis and associated right ventricular hypertrophy. Right to left shunt is also visible.

Prenatal echocardiography diagnosis of a novel combination of bilateral ductus arteriosus and cardiovascular anomalies: a case report and literature review

Frontiers in Cardiovascular Medicine

We describe a fetus with prenatal echocardiographic findings of BDA and right aortic arch mirror-image branching (RAA-MIB) combined with congenital heart disease. According to the double arch theory, BDA is formed when the distal ends of the sixth pairs of primitive arches on the left and right sides have not regressed.

This is the aortic valve in closed position and mitral valve also appears to be closed in position. You can also see the aortic override. So, when there is an aortic override, if the override of the aorta is less than 50%, you think of tetralogy of Fallot. Separation between the attachments of the aortic and mitral valve.

Deep learning denoising reconstruction for improved image quality in fetal cardiac cine MRI

Frontiers in Cardiovascular Medicine

Purpose This study aims to evaluate deep learning (DL) denoising reconstructions for image quality improvement of Doppler ultrasound (DUS)-gated fetal cardiac MRI in congenital heart disease (CHD). Diagnostic confidence was assessed for the atria, ventricles, foramen ovale, valves, great vessels, aortic arch, and pulmonary veins.
