Aortic valve stenosis due to degenerative processes is currently the most common valvular defect in the adult population. Its prevalence increases with age. The treatment of choice is surgical valve replacement. In 20–30 % of patients, mostly of advanced age, surgical valve replacement cannot be performed. In 1985, professor Cibier carried out the first balloon dilatation of a stenotic aortic valve (BAV) of this type. Soon afterwards, the effect of BAV was shown to be limited with early restenosis and a high risk associated with the procedure. Despite a certain revival after the year 2000, BAV of a degenerated aortic valve remains a largely...

Interv Akut Kardiol 2010; 9(Suppl.B): 9-13  

Percutaneous transcatheter aortic valve implantation (TAVI) is indicated in patients who are significantly limited by symptoms and whose aortic stenosis is a dominant and haemodynamically significant defect (AVA ≤ 0.5 cm2/m2). They include advanced-age patients (over 75 years), those with a high surgical risk who are not candidates for classic surgical aortic valve replacement, and specific situations when surgery is not technically feasible (porcelain aorta, following CABG, following radiation therapy in the chest area, etc.). The indications and contraindications for the procedure with respect to the specific features of CoreValve,...

Percutaneous valvuloplasty of mitral stenosis

Viliam Fridrich, Stanislav Mizera

Interv Akut Kardiol 2010; 9(Suppl.B): 14-17  

Percutaneous mitral valvuloplasty is nowadays an accepted therapeutic tool in the treatment of the patients with mitral stenosis and pliable valve. They utilized their long-term experience with indicationts and performing of this therapeutic modality. Authors describe clinical pictures of the patients with mitral stenosis, etiology and some noninvasive techniques. They are describing available interventional techniques, compare surgical and interventional approaches and their own results of the PTMV with Inoue technique.

Catheterization procedures for mitral regurgitation (Percutaneous Mitral Valve Therapies - PMVT)

Michael Želízko

Interv Akut Kardiol 2010; 9(Suppl.B): 18-20  

The review deals with catheterization techniques in patients with pure mitral regurgitation (edge-to-edge repair, annuloplasties with various approaches, percutaneous mitral valve implantation) and aims to present a brief overview of possible concepts of development of new technologies in the future.

Percutaneous transluminary pulmonary valvuloplasty isolated valvular pulmonary stenosis in adults

Ján Zelenay, Viliam Fridrich

Interv Akut Kardiol 2010; 9(Suppl.B): 21-24  

Aim: The aim of the treatment of isolated valvular pulmonary stenosis is to remove or reduce severe stenosis of the pulmonary valve without using surgical intervention. Patients and metods: Our retrospective study involved 30 patients of average age of 41.1 years (mean age 43 years). In 18 women (60 %) and 12 men (30 %) anatomical, morfological, hemodynamics and functional success of percutaneous transluminal pulmonary valvuloplasty (PTPV) was evaluated. Following parameters were evaluated: Peak systolic gradient (PSG), index of systolic intraventricular pressures (ISIVP) and pulmonal valve surface area index (PVSAI). Result: Before PTPV...
