INTRODUCTION The Venus p‑valve (MedTech, Shanghai, China) is a self-expanding percutaneous heart valve designed to be implanted in a native patched right ventricle outflow tract. The worldwide clinical experience with this valve is just beginning and the results have so far been encouraging. We present our initial early experience implanting the Venus p‑valve in the native right ventricle outfl...

Percutaneous pulmonary valve implantation (PPVI) is now an accepted alternative option to conventional surgery for patients with dysfunctional conduits between the right ventricle and pulmonary artery. PPVI will reduce the total number of repeat operations in such patients. However, surgery remains the primary option in postoperative tetralogy of Fallot patients with severe pulmonary regurgitat...

endocarditis is rarely reported in sheep and information presented for ovine endocarditis is based mostly on comparative findings in the cattle. infective vegetative endocarditis of the right heart was diagnosed in a 3-year-old fat-tailed ram. clinical findings included tachycardia, marked brisket edema, jugular veins distention and pulsation and pale mucous membranes. hematologic abnormality i...

OBJECTIVES N-terminal B‑type natriuretic peptide (NT-proBNP) is an important biomarker for the detection of heart failure. Adults with congenital heart disease (ACHD) and a prosthetic heart valve are at risk for heart failure. This study aimed to determine the value of NT-proBNP in ACHD patients with a prosthetic valve and investigate its relationship with cardiac function and exercise capacity...

Percutaneous heart valve replacement is currently limited to the replacement of pulmonary and aortic valves in a targeted group of patients. Designing a heart valve for mitral valve replacement is further limited by its distinctive anatomical feature, which places a constraint on its range of design options. To overcome such limitations, the objectives of this study were to use computational mo...

BACKGROUND The ideal prosthesis for aortic valve replacement in children and young adults has not been found yet. In recent years there has been a renewed interest in the replacement of aortic valve with the pulmonary autograft owing to its advantages of lack of anticoagulation, potential for growth and excellent haemodynamic performance. The purpose of this study was to review our institutiona...

Percutaneous mitral valvuloplasty has been proposed as a nonsurgical technique for treating high-risk patients with mitral stenosis who are deferred from mitral valve replacement. The effect of this technique on patients with pulmonary hypertension, however, has not been fully evaluated. Accordingly, serial assessment of pulmonary vascular resistance was made in 14 patients with critical mitral...

UNLABELLED A 67-year-old man with myelodysplastic syndrome, disseminated histoplasmosis, and mitral valve replacement presented with dyspnea and peripheral edema. Transthoracic echocardiography demonstrated abnormal pulmonic valve with possible vegetation. Color flow imaging showed laminar flow from main pulmonary artery into right ventricular outflow tract (RVOT) in diastole. The continuous wa...

Abstract A 33-year-old female patient with advanced idiopathic pulmonary artery hypertension underwent bilateral lung transplantation. The postsurgical course was complicated by prolonged mechanical ventilation and acute hypoxemia with recurrent episodes of pulmonary edema. An echocardiogram revealed improved right-sided pressures along with a dilated left atrium, a structurally normal mitral v...
