Abstract 4147910: 22q11 Deletion Syndrome: A Potenitial Risk Factor For Left Pulmonary Artery Hypoplasia and Need For Intervention in Patients With Congeital Heart Disease

Circulation

Animal studies have shown that mice with TBX1 gene mutations have smaller left pulmonary arteries compared to wild type mice, defined by a reduced left pulmonary artery (LPA) to right pulmonary artery (RPA) ratio. A single study has shown this translates to humans with 22q11 and structurally normal hearts.

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.

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.

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.

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.
