Background Real‐time (RT) phase contrast (PC) flow MRI can potentially be used to measure blood flow in arrhythmic patients. Undersampled RT PC has been combined with online compressed sensing (CS) reconstruction (CS RT) enabling clinical use. However, CS RT flow has not been validated in a clinical setting.

Towards Patient-Specific Surgical Planning for Bicuspid Aortic Valve Repair: Fully Automated Segmentation of the Aortic Valve in 4D CT [PDF]
The bicuspid aortic valve (BAV) is the most prevalent congenital heart defect and may require surgery for complications such as stenosis, regurgitation, and aortopathy. BAV repair surgery is effective but challenging due to the heterogeneity of BAV morphology. Multiple imaging modalities can be employed to assist the quantitative assessment of BAVs for

Transcatheter closure of Ventricular Septal defects in Malta : initial experience [PDF]
Ventricular septal defects (VSD) consist of deficiencies of the wall separating the two ventricles. VSDs are the commonest congenital cardiac defects. Small VSDs rarely require intervention, however, larger defects cause ventricular volume overload with ...

ABSTRACT Objective Cardiovascular disturbances are common in twin‐twin transfusion syndrome (TTTS). However, the rate of improvement in cardiovascular burden in response to selective fetoscopic laser photocoagulation (SFLP) is not well known. Method Fetal echocardiograms were performed prior to and 1 week following SFLP.
