[Rupture of the sinus of Valsalva aneurysm complicated by infective endocarditis -- diagnosis difficulties]. / Perforacja tetniaka zatoki Valsalvy powiklana infekcyjnym zapaleniem wsierdzia -- trudnosci diagnostyczne.

Aneurysm of the sinus of Valsalva is a rare congenital heart disease. It constitutes about 0.14%-1.5% of congenital heart surgery cases. Aneurysm of the sinus of Valsalva can be asymptomatic for many years. Only rupture of the sinus of Valsalva aneurysm leads to hemodynamic disturbances which in turn causes rapid deterioration of patient clinical condition. Some of the congenital heart diseases can be complicated by of infective endocarditis. This case report concerns the rupture of the sinus of Valsalva aneurysm in a 45 year old woman, which caused infective endocarditis on the tricuspid valve, which has been initially diagnosed as a complication of congenital heart disease in the form of the intraventricular defect.

[Assessment of possible correlations between endogenous androgens and the extent of coronary heart disease and left ventricle function]. / Badanie korelacji stezenia meskich hormonów plciowych ze stanem zaawansowania choroby wiencowej i funkcja lewej komory serca.

In men, androgens and especially testosterone are considered responsible for the much higher rate of coronary artery disease. The male gender is an independent coronary artery disease risk factor. An adverse correlation between endogenous testosterone levels and the extent of coronary atherosclerosis has been demonstrated in just one study. In our study, we investigated the associations between endogenous sex hormone levels and the extent of coronary atherosclerosis, ejection fraction of the left ventricle and coronary heart disease risk factors.

An assessment of correlations between endogenous sex hormone levels and the extensiveness of coronary heart disease and the ejection fraction of the left ventricle in males.

This clinical study investigated the possible associations of male sex hormone with the extensiveness of coronary artery lesions, coronary heart disease risk factors and ejection fraction of the heart. Ninety six Caucasian male subjects were recruited, 76 with positive and 20 with negative coronary angiograms. Early morning, prior to haemodynamic examination all of them had determined levels of total testosterone, free testosterone, free androgen index (FAI), sex hormone-binding globulin (SHBG), oestradiol, luteinizing hormone, follicle-stimulating hormone, plasma lipids, fibrinogen and glucose. The ejection fraction and the extensiveness of coronary lesions of each subject was assessed on the basis of x-ray examination results using Quantitative Coronary Angiography (QCA) and Left Ventricular Analysis (LVA) packages on the TCS Acquisition workstation, Medcon. Men with proven coronary heart disease had significantly lower levels of total testosterone (11.9 vs 21.2 nmol/l), free testosterone (45.53 vs 86.10 pmol/l), free androgen index (36.7 vs 47.3 IU) and oestradiol (109.4 vs 146.4 pmol/l). The level of testosterone was negatively associated with the DUKE Index. The most essential negative correlation was observed between SHBG and atherogenic lipid profile (low high-density lipoprotein, high triglycerides). Ejection fraction was substantially lower in patients (51.85 vs 61.30) (without prior myocardial infarction) with low levels of free-testosterone (23.85 vs. 86.10 pmol/l) and FAI (28.4 vs 47.3 IU). A negative correlation was observed between total testosterone, free testosterone, FAI and blood pressure, especially with diastolic pressure. Men with proven coronary atherosclerosis had lower levels of endogenous androgens than the healthy controls. For the first time in clinical settings it has been demonstrated that low levels of free-testosterone was characteristic for patients with low ejection fraction. Numerous hypothesies for this action can be proposed but all require a proper evaluation process. The main determinant of atherogenic plasma lipid was low levels of SHBG suggesting its main role in developing atheroscerotic lesions.
