BACKGROUND Outcome after surgery for cardiac myxoma is very good, although due to relatively low prevalence in general population there are only a few reports with long-term follow-up that involved large number of patients. AIM To evaluate short- and long-term outcome after myxoma removal in a single cardiac surgical centre. METHODS The study involved(More)
Apoptosis is recognized as a mechanism of cell loss in the setting of acute myocardial infarction (AMI). Whether it contributes to myocyte elimination late after AMI has not yet been confirmed. We attempted to identify the features of apoptosis in myocytes that survived AMI. A search for ongoing apoptosis was performed in samples obtained from 38 human(More)
AIM To assess the relationship between infarct-related artery (IRA) stenosis and capillary density and to assess its effect on scar formation in the human heart. MATERIALS AND METHODS Morphometric evaluation was performed in 51 human hearts, as follows. Group I non-cardiac death (control), Group II post-Q-wave myocardial infarction (QMI) death and Group(More)
BACKGROUND Sildenafil, a phosphodiesterase-5 inhibitor, has been shown to decrease pulmonary vascular resistance (PVR) in patients with heart failure. The purpose of the study was to evaluate the effect of sildenafil on clinical status and pulmonary vascular reactivity in patients with congestive heart failure. MATERIAL AND METHODS We enrolled 20 patients(More)
OBJECTIVE The aim of the study was to assess the effect of surgical revascularization [coronary artery bypass grafting (CABG)] on systolic function and perfusion of the left ventricle using dobutamine echocardiography (DE) and Tc-99m-MIBI SPECT (SPECT). METHODS There were 32 patients mean age 52.2+/-7.2 years in whom DE and SPECT were performed before and(More)
BACKGROUND A new formulation of tacrolimus that is characterized by prolonged release has been developed to facilitate treatment and patient compliance. Initial therapy with prolonged release formula in heart transplantation is not widely accepted. MATERIAL AND METHODS We enrolled 19 patients into a randomized analysis divided into 2 groups with different(More)
BACKGROUND AND AIMS OF THE STUDY This retrospective study evaluated late results of surgical treatment of partial anomalous pulmonary venous connection (PAPVC) concomitant with sinus venosus-type atrial septal defect (ASD) with the use of pericardial patch technique. METHODS Between 1981 and 1995, 25 consecutive patients (18 females, seven males)(More)
To evaluate whether nitroglycerin administered before the injection of sestamibi improves the detection of viable but hypoperfused myocardium, 41 post-infarction patients with left ventricular dysfunction underwent echocardiography and SPET at rest and after nitrate administration. In 25 revascularized patients, perfusion at rest and contractility were(More)
A study was conducted to assess the early results of isolated coronary artery bypass grafting in women and to determine the risk factors for early postoperative complications. Between January 1994 and July 2001, 1,730 patients (301 women and 1,429 men) underwent isolated myocardial revascularization. Conventional bypass procedure was performed on 1,554(More)
BACKGROUND Although survival among heart recipients has increased, a limiting factor is chronic adverse effects of immunosuppression therapy. MATERIAL AND METHODS We performed a retrospective analysis of 22 patients (19 men and 3 women) with a mean age of 48 ± 12 years who underwent orthotropic heart transplantation. There were 20 (91%) patients who(More)
