[Active valvular infective endocarditis: problems of surgical treatment].

The authors analyze the results of surgical treatment of patients suffering from active endocarditis with impairment of the mitral, aortal and tricuspid valves and their combinations in 242 patients operated on during 1969 to 1989. The total hospital mortality is at the level of world statistics and constitutes 15.3% (37 patients died). The main cause of the hospital mortality was acute progressive heart failure (48.6%). The long-term results of the surgery were examined in 202 patients. By the 5th observation year the total survival was 73.2%, the stability of good results 83.6%. The defined grades of the activity of infectious process play an important role in the diagnosis and treatment of patients with active valvular infectious endocarditis.

[Experience with a prosthesis of the pulmonary artery trunk at the A.N. Bakulev Institute of Cardiovascular Surgery, Academy of Medical Sciences, USSR].

From April 1975 to March 1991 sixty-four operations were carried out on 61 patients with various congenital heart diseases attended by impaired anatomical connection between the right ventricle and the pulmonary arteries. The patients' ages ranged from 9 months to 28 years (8 years on average). The most frequent clinical diagnoses were total transposition of the great vessels with ventricular septal defect and stenosis of the pulmonary artery (26 cases), type I common arterial trunk (14), Fallot's tetralogy (11 cases). Origin of the aorta and pulmonary artery from the right ventricle with stenosis of the pulmonary artery was encountered in 5 cases, origin of the aorta and pulmonary artery from the left ventricle with stenosis of the pulmonary artery in 4, and type II atresia of the pulmonary artery in one case. Three patients were reoperated on (reimplantation of an artificial pulmonary trunk). Synthetic prostheses with a biological (xenoaortic) valve made at the Institute, Bjerk-Sheily (USA) and Tascon Medical Technology (USA) "conduits", and synthetic prostheses devoid of valves were used. A "fresh" aortic alloprosthesis was used in one case. A statistically significant tendency towards reduction of operative mortality has been recorded (the mortality rate for the last 5 years is 14%). The late-term postoperative results were studied in 30 patients in follow-up periods of 12 months to 14.5 years (5 years and 5 months on average). Analysis of the late-term results shows the method to be highly effective. Stenosis of the prosthesis is the most significant problem of the late-term period.

[Problem of pulmonary hypertension in determining the indications for an operation in congenital heart defects].

The authors studied the indications for surgical treatment of patients with congenital heart diseases and increased pulmonary blood flow, depending on the degree of pulmonary hypertension. Particular attention is focused on the indications for operation in ventricular septal defect. The work is based on the experience of the workers of the institute, embracing 3,521 operations performed on this category of patients among whom there were 863 children under 3 years of age. The indications for surgery are determined in conformity with clinico-hemodynamic groups according to a classification elaborated at the institute. The late results studied in 213 patients in follow-up periods of up to 12 years show that the main evidence of the efficacy of surgical treatment are the hemodynamic data, which determine the prognosis and the subsequent working capacity of the patients.

[Basic courses of approach to the surgical treatment of postinfarct defects of the interventricular septum].

The authors studied 20 patients with postinfarction ventricular septal defects; among them 9 had been operated on and 2 of these patients died. Eleven patients did not undergo operation, 10 of them died. All patients subjected to operation had severe circulatory insufficiency; in 3 the septal defect was of nor more than one month's duration. Patients whose condition was particularly severe were subjected to intubation, catheterization of the heart, left ventriculo- and coronarography, and after the operation has been planned they were operated on on the same day. Some patients who could move about but who also suffered from circulatory insufficiency were operated on according to the planned schedule. In 10 patients who had died without being operated on the anatomy of the defect and the condition of coronary circulation were examined. The authors contend that before undertaking an operation it is necessary to assess the patient's condition and the possibility of operating on him and determine the role of the ventricular septal defect and the hemodynamic disturbances consequent upon the infarction; all cardiac lesions should be corrected during the operation. Besides closure of the defect and resection of an aneurysm 2 patients also underwent operation for aorticocoronary shunt.

[Hyperbaric oxygenation (current state and perspectives of its use in heart surgery)].

The current status of hyperbaric oxygenation (HBO) permits a preliminary determination of the optimum regimen with reference to the particular type of pathology to be treated and the method of treatment involved (surgery, resuscitation, therapy). The experimental section presents an analysis of the results of the combined effect of hyperbaric oxygenation and hypothermia, HBO and extracorporeal circulation. An extended series of experiments was conducted determining the optimum regimens of HBO in different types of hypoxia (circulatory, including cardiogenic shock, anemic, hypoxic). The clinical section presents the experience with HBO in 136 patients (118 cardiac procedures, and 18 emergency cases). The authors have the world's greatest experience with extracorporeal circulation under HBO. The priority is using this method for childbirth by women with severe heart diseases belongs to Soviet medicine. HBO was successfully used for the management of air embolism complicating openheart surgery.

[Evolution of pulmonary hypertension in the late period following correction of congenital heart defects].

The presented analysis is based on the data of haemodynamics studies in 62 congenital heart disease patients prior to and following surgery within 1 to 13 years (mean -- 5 years). Patent arterial duct ligation was performed in 34 cases, ventricular septal defect was closed in 28. Twenty of the patients had moderate, 42 -- high pulmonary hypertension (IIIa stage in 37 cases, IIIb stage -- in 5). Late postoperative haemodynamic studies have shown that Stage II patients demonstrated its normalization, the pulmonary artery pressure remaining above the normal level only in few cases in whom it had been 50 mm Hg and higher. In IIIa stage patients no normalization of haemodynamics is usually achieved, and in 9.1% of the cases an evolution of the total pulmonary resistance was noted. However, a distinct improvement of the haemodynamic parameters in the majority of such cases proves the efficacy of their urgical management. The persistence of high pulmonary hypertension or its progressive course in IIIb stage patients, caused by the spreading of the sclerotic process in the pulmonary vessles, indicates the inefficacy of surgery in this group of patients.
