Novel 3-Dimensional Image Fusion Software for Live Guidance of Percutaneous Pulmonary Valve Implantation.
A 7-year-old patient (28 kg) born with aortic stenosis, having undergone the Ross procedure and a repeat surgical intervention including patch plasty of the stenosed conduit and mechanical valve implantation in the mitral position, presented with recurrence of right ventricular outflow tract conduit narrowing. Transthoracic echocardiography showed obstruction of the conduit (V max =4 m/s) with ...
متن کاملPercutaneous 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...
متن کاملPercutaneous 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...
متن کاملPercutaneous aortic valve implantation using novel imaging guidance.
Thorough imaging of the aortic valve and related structures is highly important before and during percutaneous valve implantation. However, imaging modalities currently used in the catheterization room, namely, conventional aortography and transesophageal echocardiography are limited in guiding the precise valve placement during the implantation procedure. A novel real-time imaging modality cap...
متن کاملPercutaneous 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...
