ABSTRACT

After the analysis of the long-term outcomes of aortic coarctation isolated resection the authors noted that many of the patients had valvular defects missed for diagnosis before the operation. ECG and X-ray of the heart established valvular defects in 37% of the operated patients. 61% of them had bicuspid valve associated in 80% of cases with pathologically dilated ascending aorta. Correlation-regression analysis showed the existence of a significant correlation between the width of the ascending aorta and age of the operated patient. This width in bicuspid valve patients was correlated with systolic and diastolic pressure, physical performance before surgery. Follow-up of patients after resection of aortic coarctation should be especially careful for patients with bicuspid aortic valve with dilatation of the ascending aorta and high arterial pressure.

ABSTRACT

Arterial hypertension was detected in 40 (59.7%) of 67 patients operated on for aortic coarctation. The patients' age ranged from 15 to 35 years. The hypertensives whose physical working capacity corresponded to that of healthy persons showed no increase in stroke index and an inadequate rise of cardiac index with preserved left ventricular in tropic function and high specific peripheral resistance developed due to irreversible structural changes in the vascular bed. Hence, an elevation in blood pressure is due to high peripheral resistance. To make recommendations on exercises for patients undergoing aortic coarctation resection bicycle ergometric test should be performed along with studies of hemodynamic parameters.

ABSTRACT

The paper is concerned with a study of arterial hypertension in the long-term periods after the resection of coarctation of aorta in 77 patients aged 6 to 35 years. The complex of the patients' examination included bicycle ergometry. Arterial hypertension was revealed in 59.7% of the patients. In 83.2%, adequate correction was performed, in 16.8%, recoarctation was suspected. The rate of the development of hypertension in the operated under 16 years depends on the grade of the systolic AP increase before the operation. In those operated on in the older age, the rate of arterial hypertension depended on the time elapsed after the operation and the age by the moment of examination. In 50% of arterial hypertension patients, the work fitness corresponds to that in healthy subjects, in 28%, it constitutes 75% of the level seen in healthy subjects, and in 22%, it is low. Indications for operation in persons under 16 years rest on the grade of the arterial pressure increase; in the older age, indications are not dependent on the arterial pressure level.

ABSTRACT

Examined were 42 patients with aortal coarctation at the age of from 6 to 35 years. The differences in hemodynamics, microcirculation and oxygen regimen of tissues depending on the degree of aortal coarctation were revealed. To diagnose the degree of aortostenosis, it is suggested to use the transcutaneous monitoring of PO2 distally to the site of coarctation.
