Multi-modality imaging for percutaneous pulmonary valve implantation – getting serious about radiation and contrast reduction

Percutaneous pulmonary valve implantation

INTRODUCTION Percutaneous pulmonary valve implantation (PPVI) is one of the most exciting recent developments in the treatment of structural heart disease and has evolved as an attractive alternative to surgery in patients with dysfunctional right ventricle-pulmonary artery conduits. Although surgical pulmonary valve replacement is associated with low morbidity and mortality rates, there are ma...

Percutaneous Pulmonary Valve Implantation

Pulmonary regurgitation (PR) is a frequent sequelae after repair of tetralogy of Fallot, pulmonary atresia, truncus arteriosus, Rastelli and Ross operation. Due to patient growth and conduit degeneration, these conduits have to be changed frequently due to regurgitation or stenosis. However, morbidity is significant in these repeated operations. To prolong conduit longevity, bare-metal stenting...

Percutaneous Mitral Valve Intervention and modelling with multi-modality imaging

Functional mitral regurgitation (MR) is a common finding occurring in 20% of the general population1 and nearly 40% of heart failure patients exhibiting at least moderate regurgitation.2 severity of MR predicts mortality3 and increased morbidity in ischaemic and non-ischaemic aetiologies4, regardless of revascularisation techniqueas well as in asymptomatic patients.5 Mitral valve repair, by sur...

Percutaneous Pulmonary Valve Implantation for RVOT Defects

C ongenital cardiac defects involving the right ventricular outflow tract (RVOT) require initial surgical interventions as early as the neonatal period. These defects may include severe pulmonic valve stenosis, pulmonary atresia with or without ventricular septal defect, tetralogy of Fallot, transposition of the great arteries, and truncus arteriosus. In addition, congenital aortic valve defect...
