Homograft - the optimal aortic valve substitute?
valvuloplasty can be performed safely and with satisfactory results in over 85% of these patients. It is also possible that repeat PMV can be performed in these patients with acceptable risks and results. In our own single centre experience in about 390 procedures repeat percutaneous balloon valvuloplasty was performed in 17 cases (mean age 65 13 years) without any increase in the rate of acute...
متن کاملFabrication and characterization of nanofibrous tricuspid valve scaffold based on polyurethane for heart valve tissue engineering
Objective(s): Tissue engineering represents a new approach to solve the current complications of the heart valve replacements by offering viable valve prosthesis with growth and remodeling capability. In this project, electrospinning and dip coating techniques were used to fabricate heart valve constructs from medical grade polyurethane (PU). Methods: Fir...
متن کاملRight sided heart evaluation after successful mitral valve replacement.
Introduction: It is well-documented that right-sided heart dysfunction and significant tricuspid valve regurgitation (TVR) have adverse effects on patient outcomes after left-sided heart valve surgery. Therefore, the evaluation of right ventriclular (RV) function and TR severity in patients who had undergone mitral valve replacement (MVR), associated with/without concomitant su...
متن کاملVena cava as autologous tissue for pulmonary valve substitute.
In this study, we report on our first experience with the construction of a valve using autologous vena cava tissue for right ventricular outflow tract reconstruction. Simulating the clinical situation valves were built from tubular pieces of porcine inferior vena cava placed in a PTFE tube and investigated in a pulsatile flow simulator. Based on the given vena cava dimensions, conduits were co...
متن کاملTrans-catheter Bioprosthetic Heart Valve Implantation in Iran (Tehran Heart Centre Experience)
Introduction: With the development of interventional cardiology in the world, in addition to coronary and aortic diseases, the treatment of heart valve diseases through catheters has recently begun. The treatment of aortic stenosis (which was only possible with open surgery and valve replacement) was first performed in the world in 2002 by Alain Cribier in France with catheter insertion of the ...
