1. The number of adult patients undergoing surgery for congenital cyanotic defects in childhood has increased significantly. Therefore, the aim of the present study was to examine the effect of perinatal hypoxia on the tolerance of the adult myocardium to acute ischaemia-reperfusion injury. 2. Pregnant Wistar rats were exposed to intermittent hypobaric(More)
Clinical and experimental studies have repeatedly indicated that overloaded hearts have a higher vulnerability to ischemia/reperfusion injury. The aim of the present study was to answer the question whether the degree of tolerance to oxygen deprivation in hearts of spontaneously hypertensive rats (SHR) may be sex-dependent. For this purpose, adult SHR and(More)
BACKGROUND The goal was to examine the hemodynamic and clinical effects of long-term therapy with PDE5 inhibitor sildenafil (SILD) in patients with advanced, pre-transplant heart failure (HF) and severe pulmonary hypertension (PH), in comparison to a similar control group (CON). METHODS In this non-randomized, retrospective case-control study, 32(More)
Pulmonary hypertension (PH) unresponsive to pharmacological intervention is considered a contraindication for orthotopic heart transplantation (OHTX) due to risk of postoperative right-heart failure. In this prospective study, we describe our experience with a treatment strategy of improving severe PH in heart transplant candidates by means of ventricular(More)
The diagnosis of traumatic rupture of the descending thoracic aorta used to be an indication for urgent surgery. Recently, there has been a shift in the perspective regarding the need for an urgent procedure and increasing numbers of surgeons tend to suggest that it is safer to manage first other serious injuries and to perform reconstruction of the injured(More)
BACKGROUND Levosimendan improves myocardial contractility, and increases systemic, pulmonary and coronary vasodilation. The present study investigates the perioperative hemodynamic effects of a prophylactic infusion of levosimendan in high-risk cardiac surgery patients with severe left ventricle dysfunction, and compares short-term clinical outcomes with a(More)
Tissue glues are used during surgical treatment of acute aorta dissection although some glues release toxic products and thus alter the histological structure of the vessel wall. The aim of our study was to use a porcine experimental model of infrarenal aorta dissection to compare histological changes of the vessel wall 1, 6 and 12 months after application(More)
OBJECTIVE The present analysis of the Surgical Treatment for Ischemic Heart Failure randomized trial data examined the left ventricular volumes at baseline and 4 months after surgery to determine whether any magnitude of postoperative reduction in end-systolic volume affected survival after coronary artery bypass grafting alone compared with bypass grafting(More)
The main complication of aortocoronary reconstruction with vein grafts is restenosis in the course of time. The aim was to assess the effect of a periadventitial polyester mesh releasing sirolimus on intimal hyperplasia of autologous grafts. We implanted v. jugularis ext. into a. carotis communis in rabbits. The vein graft was either intact, or was wrapped(More)
