Abstract Congenital heart disease (CHD) affects about 1% of live births. Among them, about 20% will undergo one or more surgical or percutaneous maneuvers on the right ventricle outflow tract or pulmonary valve. Transcatheter pulmonary valve implantation is a recently available less invasive alternative to surgery for treatment of right ventricular outflow tract dysfunction. Thus, residual dysfunction can be treated early and with a lower risk profile. This narrative review aimed to describe the state of the art of percutaneous pulmonary valve implantation. More >

Abstract This study applies the diatonic chord in music theory, utilization rate, and the close relationship between the main chord system, the dominant chord system, and the subordinate chord system. From the perspective of music theory, the computer can automatically and quickly analyze the music, and establish a set of algorithms for configuring the chord accompaniment for the main melody, called the symmetrical circle of fifths algorithm, SCFA (Symmetrical Circle of Fifths Algorithm). SCFA can immediately confirm the key, perform harmony analysis, configure chord accompaniment for the main melody, and effectively and correctly complete any given More >

Abstract Pulmonary valve implant is frequently necessary in children and adults with congenital heart disease. Infective endocarditis represents a rare but life-threatening complication after transcatheter pulmonary valve implantation. There are various treatments for native or prosthetic valve endocarditis. Surgical intervention, combined with intravenous antibiotic treatment, is of paramount importance, in case of concomitant mediastinal infection, in order to ensure the radical debridement of all infected tissue, avoiding any recurrent endocarditis. In this report, we describe a rare case of mediastinitis, associated with an infected endocarditis, occurring 8 months after Melody (Medtronic^®, Minneapolis, USA) valve implant, successfully treated More >

Abstract Objective: We sought to describe the leaflet morphology variation in the Melody Transcatheter Pulmonary Valve (TPV) and evaluate associated outcomes. The Melody TPV is constructed from harvested bovine jugular venous valves which have been rigorously tested. Natural anatomic leaflet variations are seen in the Melody TPV but have not been evaluated.
Design: A Melody TPV leaflet morphology classification system was devised after reviewing a subset of photographed and implanted TPVs. All images were blindly re‐ viewed by implanters and classified. Midterm hemodynamic outcomes and complica‐ tions of the Melody TPVs were compared by leaflet morphology.
Results: Photographed Melody… More >

Abstract Objective: Trans-catheter (TC) pulmonary valve replacement (PVR) has become common practice for patients with right ventricular outflow tract obstruction (RVOTO) and/or pulmonic insufficiency (PI). Our aim was to compare PVR and right ventricular (RV) function of patients who received TC vs surgical PVR.
Design: Retrospective review of echocardiograms obtained at three time points: before, immediately after PVR, and most recent.
Patients: Sixty-two patients (median age 19 years, median follow-up 25 months) following TC (N = 32) or surgical (N = 30) PVR at Yale-New Haven Hospital were included.
Outcome Measures: Pulmonary valve and right ventricular function before, immediately after,… More >
