Dysfunctional pulmonary artery conduit and co-existing large pseudoaneurysm: well-suited for a percutaneous approach with the Melody valve?
نویسندگان
چکیده
Pseudoaneurysm formation is a rare but potentially life-threatening complication after surgical repair of congenital heart disease. We present a boy with truncus arteriosus communis 14 years after homograft placement in pulmonary position. On follow-up, he presented progressive chronic homograft degeneration. Moreover, a large pseudoaneurysm in the right ventricular outflow tract was surprisingly depicted. We opted for a two-stage interventional approach.

Implantation of the melody transcatheter pulmonary valve in patients with a dysfunctional right ventricular outflow tract conduit early results from the u.s. Clinical trial.
OBJECTIVES This study was designed to evaluate the safety, procedural success, and short-term effectiveness of the Melody transcatheter pulmonary valve (Medtronic, Inc., Minneapolis, Minnesota) in patients with dysfunctional right ventricular outflow tract conduits. BACKGROUND Conduit dysfunction has recently been treated with transcatheter pulmonary valve placement. There have been no prospe...
متن کاملFeasibility and short-term outcomes of percutaneous transcatheter pulmonary valve replacement in small (<30 kg) children with dysfunctional right ventricular outflow tract conduits.
BACKGROUND In 2010, the Melody transcatheter pulmonary valve (TPV) received Food and Drug Administration approval for treatment of dysfunctional right ventricular outflow tract conduits in patients ≥30 kg. Limited data are available regarding use of this device in smaller patients. METHODS AND RESULTS We evaluated technical and short-term clinical outcomes of 25 patients <30 kg (10 patients <...
متن کاملShort-term performance of the transcatheter Melody valve in high-pressure hemodynamic environments in the pulmonary and systemic circulations.
BACKGROUND The Melody valve is approved for percutaneous pulmonary valve replacement in dysfunctional right ventricular outflow tracts. The function of this valve when subjected to high-pressure loads in humans is unknown. The aim of this study was to describe the immediate and short-term results of Melody valves implanted in a high-pressure environment. METHODS AND RESULTS Definitions of a h...
متن کاملLarge coronary pseudoaneurysm with pulmonary artery fistula, six months after left main trunk stenting with paclitaxel-eluting stent.
There are no reported cases of a pseudoaneurysm leading to a fistula into the pulmonary artery after percutaneous coronary intervention. We describe a patient who developed a late pseudoaneurysm after left main trunk (LMT) stenting with paclitaxel-eluting stent, discovered during coronary angiography. Transesophageal echocardiography and contrast-enhanced computed tomographic scan revealed a pe...
متن کاملTranscatheter pulmonary valve replacement: valves, techniques of implantation and outcomes
Transcatheter pulmonary valve replacement has changed the way we approach congenital and structural heart disease. In patients with a conduit between the right ventricle and pulmonary artery or a bioprosthetic pulmonary valve, there will eventually be pulmonary valve dysfunction. This leads to right ventricular failure and possibly arrhythmias. Due to prior operations and the comorbid condition...
