[Aortico-left ventricular tunnel].
The boy was first admitted to the Department of Pediatric Cardiology at the age of 4 1/2 because of cardiac murmur diagnosed on the third day of life. A diastolic murmur of a grade 4/6, left ventricular hypertrophy as well as left aortal and ventricular dilatation were discovered. The findings showed a tendency of increase with time, but the patient had no symptoms. X-ray in the long axis view revealed a defect within the upper part of the interventricular septum immediately below the aorta, and dilated right coronary sinus. An invasive diagnostic method was undertaken, as well. The operative procedure was done with a total cardio-pulmonary bypass and hypothermia (29 degrees C). A tunnel from the anterior aortal wall through the outflow tract of the right ventricle to the left side of the heart was established intraoperatively. The defect was solved by a "sandwich" technique (two patch technique). Postoperative period was uneventful. A Doppler echocardiogram demonstrated the normal hemodynamic status of the patient without the left-to-right or right-to-left shunt and aortal insufficiency.

[Surgical treatment of congenital obstruction of the left ventricular outflow tract].
This report presents the classification and all types of left ventricular outflow tract obstructions. The possibilities of operative therapies are surveyed as well. Results of surgical treatment in 34 patients with obstruction to left ventricular outflow are shown. The majority of patients underwent operation under extracorporeal circulation (84.4%), while the rest were operated by means of the inflow occlusion technique (14.7%). The obtained results were compared with those from the literature. The importance of echocardiographic evaluation of location of the left ventricular outflow tract obstruction and the appropriate choice of a surgical technique according to the patient's age are emphasized.

[Acute renal failure in heart transplantation].
In this study the incidence and the development of acute renal failure (ARF) in heart transplant recipients is presented. Among the thirteen heart transplant recipients eight of them developed oliguric or nonoliguric ARF. Besides the known factors such as actual condition of the patient, kidney function, peri and post-operative compromised circulation, our results demonstrate the significance of postoperative cyclosporin concentration in combination with the use of other drugs. The results also show the importance of the way cyclosporin has been administrated. The parenteral route of appliance is connected with the greater risk of higher drug concentration in the plasma than the peroral one. In connection with this is the higher incidence of adverse reactions to cyclosporin given parenterally. In addition to ranitidine and captopril, which have been mentioned earlier, the findings of our study indicate that greater attention has to be paid to the treatment with ketoconazol given in combination with cyclosporin, since it results in decreased cyclosporin clearance. Other nephrotoxic drugs like amphotericin also increase the possibility of renal lesions. The incidence of acute renal failure in this group of patients is high. Our data suggest that the reasons for the development of ARF are multifactorial. These data further suggest that a reasonable way to solve nonoliguric form of acute renal failure is to maintain the "internal balance" and that it is not necessary to perform extracorporeal elimination of nitrogen substances, if there are no additional complications (i.e. gastrointestinal bleeding).(ABSTRACT TRUNCATED AT 250 WORDS)

[Direct communication of the pulmonary artery with the left atrium].
A rare communication between the right pulmonary artery and the left atrium in a 3.5-year-old girl is described. Cyanosis of a central type and a continuous murmur over the heart were presenting symptoms. Echocardiography revealed only excessive pulsations of the pulmonary artery, while catheterization pointed to an abnormal aneurysmal communication between the right pulmonary artery and the left atrium. At this point the O2 saturation was at the level of the left atrium. The communication was clinically classified as a type IV according to Nelson. After an unsuccessful attempt through a right thoracotomy, the ligature of this fistula has been performed in the second attempt through a median sternotomy and under complete extracorporeal circulation. Clinical course and review of literature of this rare anomaly of the heart are being presented.
