Recurrent left ventricular false aneurysm.

A recurrent left ventricular false aneurysm 5 years after patch repair and causing progressive congestive heart failure was readily diagnosed by echocardiography and heart catheterization. Its substrate was suture dehiscence of undetermined origin. Urgent repair was successful.

[Immediate results of surgical treatment of intracardiac myxomas in 45 patients].

Between 1961 and 1992, 45 patients with intracardiac myxomas localised in the left ventricle--40 (89%) and in the right ventricle--5 (11%) were operated on. There were 27 women and 18 men, aged 15-63, mean age, 46.5 years.

[Infections of the sternum after cardiac surgery].

Methods of treatment of suppurative mediastinitis in cardiosurgical operations applied at the clinic are analysed. These methods are: debridment with closure of the sternum with irrigation of the substernal space, debridment with bandage of open wound and healing per secundam, debridment with bandage of open wound and its closure by myocutaneous layers. It has been concluded that these infections are very complex etiopathogenetically because of which it is very important to know all relevant risk factors aiming to prevent development of this complication in cardiosurgical operations.

Doppler echocardiographic analysis of the transmitral flow velocity profile in patients with ventricular septal defects.

Using continuous-wave Doppler echocardiography, we evaluated the mitral flow velocity pattern in 30 ventricular septal defect patients, 11 of whom had severe pulmonary vascular obstructive disease (Group I); 10 of whom had severe pulmonary hypertension without pulmonary vascular obstructive disease (Group II); and 9 of whom had no pulmonary hypertension and hemodynamically unimportant left-to-right shunts (Group III). In addition, 25 healthy subjects (Group IV) were studied for comparative purposes. The peak velocity of early left ventricular filling (E) was significantly lower in Group I than in all the other groups (p < 0.

Evaluation of the new type of military bullet and rifling.

The 5.56-mm caliber SS 109 projectile was fired from 7.7'' and 12'' twist rifles, respectively, into soap blocks and porcine thighs at 50-metre range using a standardized experimental setup.
