Cor Vasa 2002, 43(4):169-174
Aim:To evaluate the clinical status of patients at a long interval from surgery for coarctation of the aorta. Group:Out of 75 patients having surgery for coarctation of the aorta, who were evaluated at the Department of Internal Medicine of Motol University Hospital in the late 1970s, 49 patients (65%) were re-assessed after an interval of 21 years. Twenty-six patients did not present for the follow-up assessment; death certificates were provided for 7 (9%) of these patients. The re-assessed patients included 33 men (67%) and 16 women, with a mean age of 44 ± 8.3 years; interval from surgery 33 ± 8 years. Method...

Aim:To investigate the clinical benefit of positron emission tomography (PET) used to estimate myocyte metabolic activity in combination with single-photon emission computed tomography (SPECT) for myocardial perfusion studies in left ventricular (LV) myocardial viability assessment. Patients and methods:From February 2000 through October 2001, a cohort of 58 patients (46 males, 12 females; mean age 62 ± 10.2 yrs) with ischemic heart disease (IHD), as documented by coronary angiography, underwent SPECT and PET studies for myocardial viability estimation. 18F-fluorodeoxyglucose PET was used for myocardial glucose uptake...

Aim of study:(1) To evaluate the hemodynamic changes that occur on altering the position of the heart and on exposure of various segments of the myocardial wall to surgical intervention. (2) To assess the changes in hemodynamic parameters depending on the technique of target artery stabilization. Methods:We evaluated a selected group of 20 patients in 1998 (group A, pressure stabilizer), and 20 patients in 2000 (group B, negative pressure stabilizer) with three-vessel disease documented by coronary angiography. These patients were expected to be scheduled for multiple aorto-coronary bypass to all exposed areas (anterolateral...

Single-dimensional color transmitral flow mapping (color M-mode): a useful method for left ventricular diastolic function assessment
Tomáš Paleček, Aleš Linhart, Michael Aschermann
Cor Vasa 2002, 43(4):192-196
Echocardiography is considered to be the method of choice for the assessment of left ventricular diastolic function. However, differentiation of pseudonormal filling pattern, characteristic for advanced forms of diastolic dysfunction with elevated filling pressures, remains to be a problem. Analysis of left ventricular filling using color M-mode is a new echocardiographic method providing useful complementary data in the study of diastolic function. Flow velocity propagation measured by color M-mode is determined mainly by ventricular relaxation and seems to be relatively insensitive to preload. Combined with pulsed-wave Doppler analysis, color M-mode...
Catheter-based cryoablation in the management of cardiac arrhythmias
Petr Neužil, Miloš Táborský, Martin Syrůček, Josef Marek, Petr Niederle
Cor Vasa 2002, 43(4):192-196
Cryoablation during surgical procedures for managing cardiac arrhythmias has been used since the late 1970s. It was not until the development of controlled transvenous catheters that it became possible to use cryodestruction as an alternative source of energy to the well established and currently predominant radiofrequency ablation. This review article is intended to point to differences which may be used with advantage especially when using catheter-based cryoablation in a complex arrhythmic substrate, e.g., creation of multiple linear lesions in the left ventricular and atrial regions. Use of cryothermy can be characterized by three basic phases-freezing...

"Fast track" anesthesia-standard for less invasive procedures in cardiac surgery
Zbyněk Straka, Petr Brůček, Tomáš Vaněk
Cor Vasa 2002, 43(4):197-199
Introduction:The explosion of less invasive cardiac surgery, mainly in the field of coronary reconstruction without cardiopulmonary bypass (CPB), has led to the development of a new procedure, referred to as fast-track anesthesia, allowing extubation of the patient while still in the operating theater. The techniques described to date combined with endotracheal general anesthesia with thoracic epidural analgesia. Patients and methods:"Fast-track" anesthesia using an ultra-short-acting opiate without epidural catheter insertion was induced in 114 patients undergoing surgery for CHD without the use of extracorporeal circulation...
