[Intravascular hemolysis after multiple valvular replacement procedures--a case report].

A case of an intravascular hemolysis after multiple aortic and mitral valves replacement is described. Hemolysis was observed after second and third operation of mitral valve prosthesis due to prosthesis dysfunction -- paravalvular leak. We discuss the possibilities of treatment, difficulties in decision making in a patient who is in good condition but hemolysis is clinically significant, not amenable to conventional treatment and there is an increased risk of another operation.

[Can the BNP be used as a biochemical marker for assessing severity of left ventricular hypertrophy in aortic stenosis?].

UNLABELLED: Plasma natriuretic peptide type B (BNP) concentration increases in aortic stenosis (AS) but relation to severity of left ventricle hypertrophy (LVH) is unknown. We analyze the relation between BNP and the LVH (left ventricle mass index (LVMI)), left ventricle thickness (LVTh) in pts with significant aortic stenosis (AS). MATERIAL AND METHODS: 58 pts with AS (32 male), aged 62 +/- 12, underwent echocardiographic study before aortic valve replacement. BNP level was measured using SHIONORIA BNP test (immunoradiometric method). Results were expressed as a mean (+/- standard deviation). Control group consisted of 26 healthy people. Correlation between BNP level and age, gender, EF, MGA and LVH were also tested. RESULTS: In pts with AS BNP level ranged from 11 to 2010 pg/ml. Mean BNP level was similar in men and women (mean level in whole group 344 +/- 480 pg/ml) and it was higher than in control group (6,1 +/- 3,9 pg/ml). BNP level was related with LVMI (r = 0,42; p<0,001), LVDD (r=0,61; p<0,0001), EF (r = -0,66; p<0,0001 - higher BNP level in lower EF) but not with LVTh (r = -0,08; p = ns), age (r = 0,06; p = ns) and MGA (r = -0,19; p = ns). BNP in 11 pts in eccentric type of hypertrophy was significantly higher (721 +/- 773 pg/ml) then in 47 cases with concentric type of remodeling (256 +/- 337; p = 0,04). CONCLUSIONS: 1. BNP level increased in relation to left ventricle mass index (increase in left ventricle diastolic diameter) but not to wall thickness 2. BNP measurement could potentially be used to monitor left ventricle remodeling in aortic stenosis.

Analysis of the corrected QT before the onset of nonsustained ventricular tachycardia in patients with hypertrophic cardiomyopathy.

This study examined ventricular repolarization before the onset of 37 episodes of nonsustained ventricular tachycardia (NSVT) in 26 untreated patients with hypertrophic cardiomyopathy (HCM). Fourteen episodes were recorded in patients with a history of cardiac arrest or patients who died suddenly during follow-up. The QT interval was measured beat-by-beat on 24-hour ambulatory electrocardiograms. Mean 24-hour, hourly QTc and QTc of the last 10 beats prior to NSVT, consisted of 4-50 cycles (mean 9 +/- 10), at the fastest rates of 100-175 beats/min (mean 122 +/- 22) were analyzed. NSVT was more prevalent during nighttime (23 episodes), than during daytime (14 episodes, P < 0.05). No significant differences were observed between mean 24-hour, mean hourly QTc during the hour with NSVT, and QTc of the last 10 cycles prior to onset of NSVT. QTc was significantly longer in patients with a history of sudden cardiac death (SCD) or who died suddenly during follow-up than in survivors. The 24-hour QT variability was higher in nonsurvivors than in survivors (-39 +/- 6 vs 33 +/- 6 ms, P = 0.03). Episodes of NSVT in untreated patients with hypertrophic cardiomyopathy were more frequent during the nighttime. The 24-hour QT variability was higher in nonsurvivors than in survivors.

[The evaluation of the left ventricle function in patients with aortic stenosis and severe heart failure after surgical treatment of valvular heart disease].

Surgical treatment of aortic stenosis in patients (pts) with severe heart failure represents high-risk procedure. The aim of this study was to identify prognostic factors and assess the late outcome after aortic valve replacement (AVR) in patients with isolated aortic stenosis and left ventricle ejection fraction (EF) < or = 40%. The study group consisted of 37 pts 25 (67%) men and 12 (33%) women, aged 57 +/- 12 yrs. Mean follow-up period was 18 +/- 17 months (range 6 to 72 months). Before AVR and within follow-up period clinical assessment was based on NYHA classes and echocardiographic study to evaluate left ventricle function. Early mortality rate was 8.3%, late mortality was 5.8%. EF significantly improved from 27 +/- 7% to 59 +/- 15% (p < 0.001) after AVR. It was accompanied by clinical improvement. Left ventricle function improvement did not depend on age, sex of patients, concomitant revascularization and preoperative maximum transaortic gradient. Significant correlation (r = -0.4, p = 0.02) between preoperative left ventricle end-diastolic diameter and postoperative EF improvement was noted.

[Is there any difference in quality of life after 12 months surgical treatment of acquired heart valve disease in comparison to results after three months?].

The quality of life in eighty patients three and twelve months after surgical treatment of acquired heart valve disease was assessed. The significant extension of distance in 6 minute walk test and clinical improvement measured in change of NYHA functional classes after three and twelve months was noticed. However twelve months after valve replacement in comparison to results after three months no further improvement of quality of life in the matter of physical, psychical and social factors was seen.

[Influence of insertion-deletion polymorphism of the angiotensin converting enzyme gene on left ventricular hypertrophy in patients with aortic stenosis--differences in men and women].

UNLABELLED: The role of different parameters (including genetic factors) on the timing and extend of left ventricle hypertrophy in patients with aortic stenosis is not defined. In our study we analyze the influence of clinical, echocardiographic parameters and I/D polymorphism of the angiotensin converting enzyme gene on the left ventricle hypertrophy (left ventricle mass index) in this group of patients. The study was done with the group of 302 pts with aortic stenosis--120 women and 182 men; mean age 58 +/- 11 yrs. Stepwise (backward) regression was used to assess the influence of the analyzed parameters (age, gender, history of hypertension, EF, MGA, presence of significant coronary artery disease and I/D ACE polymorphism) on the LVH in the all pts and in the women and the men separately. In the whole group the LVMI depends on EF (t = -6.5; p = 0.0001--higher LVMI in lower EF), MGA (t = 3.9; p = 0.0001--higher LVMI in higher MGA) and gender (t = 2.8; p = 0.005--higher LVMI in men). In women LVMI was related with EF (t = -3.6; p = 0.001--higher LVMI in lower EF), age (t = 2.9; p = 0.004--higher LVMI in older pts) and MGA (t = 2.5; p = 0.013--higher LVMI in higher MGA). In men the LVMI depends on EF (t = -4.8; p = 0.0001--higher LVMI in lower EF) and MGA (t = 1.98; p = 0.049--higher LVMI in higher MGA). Significant relationship between LVMI and results of I/D ACE polymorphism was observed both in women and men. I/D polymorphism relationship with LVMI was divergent in these 2 groups--association of higher LVMI with lack of DD type of polymorphism in women and presence of DD polymorphism in men. CONCLUSIONS: 1. Left ventricle hypertrophy in pts aortic stenosis is higher in men than in women. 2. In women left ventricle hypertrophy is related with ejection fraction, maximal aortic gradient, age and I/D ACE polymorphism; in men it is related to EF, MGA and I/D ACE polymorphism. 3. The influence of I/D ACE polymorphism on the left ventricle hypertrophy is divergent in women and men--in women related to the lack of DD polymorphism, in men related to the presence of DD polymorphism.

[Serological tests for detection of fungal infection connected with prolonged antibiotic treatment after valve replacement].

UNLABELLED: In recent years substantial progress has been seen in the development of approaches and methods for serological diagnosis of the mycosis. The aim of our study was to assess the clinical usefulness of serological tests for fungal infection in pts who underwent prolonged antibiotic therapy after valve replacement. MATERIAL AND METHODS: The group consisted of 27 pts after valve replacement with prolonged antibiotic therapy (6-12 weeks) due to infective endocarditis (22 pts) or sternal infection (5 pts). The samples of blood were taken 10 days after antibiotics were started and next every 10 days. Serological techniques for the diagnosis of Candidiasis consisted of antibody detection to: the cell wall polysaccharide antigen (test A), cytoplasmic protein antigen (test B) and the germ tube antigens (test C). RESULTS: Patients were divided in 3 groups due to the kinetics of the antibody responses to the Candida antigen: 1. pts with normal level of antibody during antibiotic treatment--they didn't required antifungal therapy, 2. pts with increasing level of antibody needed antifungal treatment, 3. pts with increasing kinetics of antibody responses during antibiotic and antifungal treatment needed the change of antifungal therapy, 4. Control group (pts before cardiac surgery without any sign of fungal infection). Antibody to the cytoplasmic antigen was detected infrequently. The presence of antibody to the cytoplasmic antigen was correlated with the patient clinical outcome and prognosis and necessity for change of antifungal therapy. One pt died after valve replacement due to valve dysfunction because of fungal endocarditis. CONCLUSIONS: Serological tests for Candidiasis can be a useful marker of fungal infection, prognosis and treatment in pts required prolonged antibiotic therapy after valve replacement.
