Rupture of the right sinus of valsalva into the right ventricle: echocardiographic and angiographic imaging.

We report a 16-year-old girl with acute rupture of the sinus of Valsalva. This case is unique in that the right coronary sinus of Valsalva ruptured into both the right and left ventricles, producing severe aortic insufficiency. The diagnosis was made with two-dimensional and color Doppler echocardiography which showed an abnormal jet flow from the aortic root into both ventricles.

Significance of QTc prolongation on ventricular arrhythmias in patients with left ventricular hypertrophy secondary to essential hypertension.

The present study was designed to detect the arrhythmogenic effect of left ventricular hypertrophy, QTc prolongation and the relationship between the QTc duration and ventricular arrhythmias in patients with left ventricular hypertrophy secondary to essential hypertension. Sixty-eight hypertensive patients (51 male and 17 female, mean age 52+/-6 years) and 30 healthy normotensive subjects (22 male and eight female, mean age 49+/-6 years) were enrolled in the study. The frequency of ventricular arrhythmias was investigated with 24-h ambulatory electrocardiographic monitoring and grade 3 and 4 ventricular arrhythmias according to a modified Lown and Wolf classification were accepted as complex arrhythmias.

Impact of hemodialysis on comprehensive ventricular repolarization.

Cardiac arrhythmia are one of the most important problems in haemodialysis patients. An important cause of the arrhythmias is inhomogenous myocardial repolarization. In this study, the ventricular repolarization parameters (QT, QTc, JT and JTc) and dispersions (d) of the parameters (QT-d, QTc-d, JT-d and JTc-d) were evaluated.

Cardiac arrhythmias in patients on maintenance hemodialysis.

Cardiac arrhythmias were evaluated in 20 patients (14 males and 6 females; 38.2 +/- 17.6 years) undergoing regular maintenance hemodialysis (HD) for chronic and renal failure (CRF) by Holter ECG monitoring a 24-hour period.

Echocardiography and magnetic resonance imaging of sinus of Valsalva aneurysm with rupture into the ventricle.

A 53 year-old man with rupture of sinus of Valsalva aneurysm into the right ventricle diagnosed by two dimensional echocardiography (2DE), magnetic resonance imaging (MRI), and catheterisation study is reported in this paper. Despite the fact that its incidence is low, early diagnosis is very important in this illness because of the possibility of complete cure with surgery. In this study it was shown that MRI as well as 2DE is an excellent diagnostic method for this illness.

Significance of QT dispersion on ventricular arrhythmias in mitral valve prolapse.

The present study was designed to detect the arrhythmogenic effect of mitral valve prolapse, and the relationship between QT, QT dispersion and ventricular arrhythmias in subjects with mitral valve prolapse. Sixty-four mitral valve prolapse subjects (24 men and 40 women, mean age 27 +/- 6), and 80 healthy control subjects (32 men and 48 women, mean age 28 +/- 7) were studied. The frequency of ventricular arrhythmias by means of 24-h ambulatory electrocardiographic (ECG) monitoring was investigated.

The diagnostic and prognostic value of adenosine deaminase in tuberculous pericarditis.

Because of the difficulty in isolating the causative organism, pericardial tuberculosis is rarely diagnosed. Adenosine deaminase activity measured in the pericardial fluid of 108 patients was initially of undetermined origin. Subsequently, we classified five sources: (1) tuberculosis (20 cases); (2) idiopathy (82 cases); (3) neoplasia (three cases); (4) purulent bacterial infection (two cases); and (5) radiotherapy (one case).

Evaluation of lipoprotein (a) [Lp (a)] as a risk factor for coronary artery disease in the Turkish population.

Objective: Lipoprotein (a) [Lp (a)] is an atherogenic particle that structurally resembles a low-density lipoprotein (LDL) particle but contains a molecule of apolipoprotein (a) attached to apolipoprotein B-100 by a disulfide bond. Because of the fact that elevated plasma levels of Lp (a) have been shown to be an independent risk factor for coronary artery disease (CAD), we determined plasma Lp(a) levels in CAD for Turkish population, and compared them with previous findings of some developed countries.

Results: The mean plasma Lp (a) levels in CAD group (mean +/- SD; 0.

Hydatid cyst of the interventricular septum and contribution of magnetic resonance imaging.

Cardiac echinococcosis has not been reported frequently. Because of the risk of potentially lethal complications, early diagnosis and definitive treatment are very important. We report a case of a cardiac echinococcal cyst in the interventricular septum.

Impact of hemodialysis on QT interval.

Holter electrocardiographic recordings were performed for 24 hours in 20 patients with chronic renal failure on chronic hemodialysis to evaluate the effects of changes in serum calcium and potassium during hemodialysis period on the QT interval. Hemodialysis caused an increase in serum calcium from a predialysis value of 9.1 +/- 1.

The Jervell and Lange-Nielsen syndrome.

The association of prolongation of the QT interval with recurrent attacks of syncope, sudden death, and malignant ventricular arrhythmias is known as the long QT syndrome. The syndrome may be familial with or without congenital deafness, or idiopatic. The syndrome with deafness (Jervell and Lange-Nielsen syndrome) is inherited through an autosomal recessive mechanism.

Doppler evaluation of left ventricular diastolic filling in Behçet's disease.

Although cardiac involvement such as pericarditis, myocarditis, coronary arteritis and valvular disease in Behçet's disease occurs, few studies have assessed left ventricular diastolic function. This study assesses the prevalence of both systolic and diastolic left ventricular dysfunction in patients with Behçet's disease who have no clinical cardiac manifestations. Twenty-two patients (12 women and 10 men, mean age 34 +/- 2.

Tuberculous pericarditis in north-east Turkey. An echocardiographic study.

Twenty patients with tuberculous pericarditis who were referred to the Blacksea Technical University Medical School Cardiology Department from January 1979 to January 1992 were followed for 12-18 months by repeated echocardiography, before and after antituberculous therapy. Initial echocardiograms revealed moderate pericardial effusion in 7 patients (35%), and large effusion in 13 (65%). Thickened pericardium was noted in 2.

Prevalence and risk factors of varicose veins in an elderly population.

The prevalence of and risk factors for varicose veins (VV) were studied in elderly persons over 60 years of age who had visited the Tonya and Farabi Hospitals in Trabzon, a city in northeastern Turkey. VV were defined as dilated, tortuous and elongated veins of the lower extremities and were classified into four types. The total prevalence of VV was 36.
