OBJECTIVES Off-pump transcatheter valved stent implantation could be a treatment option for patients suffering from symptomatic tricuspid regurgitation (TR) who are classified as inoperable. In this study, we present our recent short-term results of transventricular tricuspid valved stent implantation and compare different stent types for atrial anchorage. METHODS Fifteen pigs received a self...

BACKGROUND Different types of nebulizers and interfaces are used for the treatment of adults and children with pulmonary diseases. The purpose of this study was to determine the efficiency of a mesh nebulizer (MN) with a proprietary adapter and a jet nebulizer (JN) under different configurations in adult and pediatric models of spontaneous breathing. We hypothesize that delivery efficiency of J...

TOPIC: Pharmacotherapeutics TYPE: Original Investigations Valved Holding Chambers/spacers are commonly prescribed for patients to aid coordination of their MDI and optimize medication delivery the lungs while filtering out larger particles that would otherwise deposit in back throat. However, many do not use valved holding chambers (VHCs) when on-the-go due portability appearance. This laborato...

Fontan's correction has been performed without early death in 24 consecutive patients with tricuspid atresia. Eighteen patients had ventriculoarterial concordance (group I) and six discordance (group II). Late death related to infections occurred in three patients. The follow-up time in group I (16 survivors) ranges from 1 year 10 months to 7 years 5 months (mean 3 years 8 months) and in group ...

OBJECTIVES To retrospectively analyze the clinical outcome of a totally biological composite stentless aortic valved conduit (No-React® BioConduit) implanted using the Bentall procedure over ten years in a single centre. METHODS Between 27/10/99 and 19/01/08, the No-React® BioConduit composite graft was implanted in 67 patients. Data on these patients were collected from the in-hospital datab...

BACKGROUND Pressurized metered-dose inhalers with valved holding chambers and masks are commonly used for aerosol delivery in children. Drug delivery can decrease when the dead-space volume (DSV) of the valved holding chamber is increased, but there are no published data evaluating force-dependent DSV among different masks. METHODS Seven masks were studied. Masks were sealed at the valved hol...

Potential drawbacks from right ventricle-pulmonary artery (RV-PA) conduit in modified Norwood procedure may be regurgitation through the conduit and incision at the systemic ventricle. In order to address the question if valved RV-PA conduit can provide hemodynamic advantages, we retrospectively reviewed the data of patients who underwent modified stage I Norwood operation with either a non-val...
