OBJECTIVES: Radiation exposure is a concern for both patients and operators during transcatheter aortic valve implantation (TAVI). Efforts to reduce radiation dose are warranted. We aimed at investigating if per-operative advanced image processing can reduce patient and operator irradiation use during TAVI. METHODS: We performed a prospective single-centre observational study comparing patient and operator radiation exposure using standard fluoroscopy (control group) or a novel technology of live advanced fluoroscopic image processing (test group) among consecutive patients undergoing TAVI between August 2015 and April 2016...

BACKGROUND:  Isolated tricuspid valve (TV) surgery is considered a high risk-procedure. The optimal surgical approach is controversial. We analyzed our experience with isolated TV redo surgery performed either minimally invasively (redo-MITS) or through sternotomy. METHODS:  We retrospectively analyzed all patients with previous cardiac surgery who underwent redo-MITS ( n  = 26) and compared them to redo-Sternotomy ( n  = 17). A group of primary-MITS ( n  = 61) served as control...

In patients who underwent transcatheter aortic valve implantation (TAVI), postoperative mortality risk is commonly assessed with risk scores such as the Society of Thoracic Surgeons-Postoperative Risk of Mortality (STS-PROM) and EuroSCORE II, in which age plays a dominant role. However, we reason that in the naturally selected oldest-old patients (nonagenarians), this may not be completely justified and that therefore age should play a minor role in decision-making. The objective of this study was to compare procedural outcome and mid-term mortality of transfemoral (TF)-TAVI patients aged ≥90 years with patients aged <90 years...

A significant prosthetic paravalvular leak is an uncommon and severe postsurgical complication correlated to the occurrence of congestive heart failure and hemolytic anemia. Percutaneous treatment has become an attractive and effective proposal to relieve symptoms and reduce complications in patients whose high rate of morbidity/mortality precludes a new surgery. This is the case of an 81-year-old patient with a history of biological aortic valve replacement seeking medical help due to heart failure and hemolytic anemia, with a prosthetic paravalvular regurgitation jet and high surgical mortality according to EuroSCORE II...
