Nowadays, percutaneous pulmonary valve treatment is a hot topic in valvular heart disease, consisting of percutaneous balloon pulmonary valvuloplasty and percutaneous pulmonary valve implantation (PPVI). The percutaneous balloon pulmonary valvuloplasty is the prime intervention of pulmonary valve stenosis. The main indication of PPVI is pulmonary valve regurgitation and/or obstruction. PPVI is still the research focus, with the improvement of surgical indications and the development of surgical devices. However, compared with surgical pulmonary valve replacement, it still has limitations. This article reviews the treatment progress of percutaneous pulmonary valve treatment, especially PPVI.
Tricuspid regurgitation (TR) is a clinically prevalent valvular heart disease with an age-dependent increase in incidence. Patients with symptomatic severe TR are confronted with limited efficacy of medical treatment and high risks of surgical intervention. In recent years, transcatheter tricuspid valve replacement has rapidly evolved as a novel therapeutic strategy to address the challenge. This article systematically reviews the design features and clinical studies of transcatheter tricuspid valve replacement devices globally, providing valuable insights and evidence for expanding clinical approaches in the treatment of the patients with TR.
