Pulmonary arterial hypertension (PAH) is a major cause of morbidity and mortality among patients with congenital heart disease (CHD). This study was designed to determine biomarker levels in patients with PAH associated with CHD (PAH–CHD) and CHD patients without PAH and to investigate the relationship of these potential biomarkers with hemodynamic(More)
BACKGROUND The aim of this study was to assess the prevalence of persistent left superior vena cava (PLSVC) in patients with all types of congenital heart defects and to determine the congenital heart anomalies accompanying PLSVC. METHODS The present study is based on a retrospective review of 1205 children who consecutively underwent cardiac(More)
OBJECTIVE The aim of this study is to determine the relationship between the cardiac catheterization findings and pulsed-wave (PW) Doppler and Doppler tissue imaging (DTI) in pulmonary arterial hypertension patients with congenital heart disease with intracardiac shunts. DESIGN AND PATIENTS The present study aims to determine the relationship between the(More)
This study aimed to determine mean pulmonary arterial pressure (PAPmean) and pulmonary vascular resistance (PVR) using transthoracic echocardiography (TTE) measurements of the pulmonary artery flow velocity curve in children with pulmonary arterial hypertension (PAH) and congenital heart disease when the tricuspid regurgitant velocity (TRV) is not(More)
The present study aims to determine the efficacy and reliability of cardiovascular magnetic resonance imaging in establishing the diagnosis and prognosis of pulmonary hypertension in children. This is a retrospective comparison of 25 children with pulmonary hypertension and a control group comprising 19 healthy children. The diagnosis of pulmonary(More)
BACKGROUND The purpose of this study was to assess the effects of abdominal compartment syndrome (ACS) on the kidneys. METHODS Intra abdominal pressures (IAP) were indirectly measured through urinary bladder. The patients were categorised into four groups according to IAP levels. Serum urea and creatinine levels and IAP were measured once a day. Abdominal(More)
PURPOSE Hydatid cyst is still a significant health and economical problem due to insufficient preventive measures. Infestation by hydatid disease in humans most commonly occurs in the liver and causes complications unless treated properly. Therefore, hepatic hydatid cyst should immediately be treated when diagnosed. Today, the treatment of hydatid cysts is(More)
BACKGROUND Postoperative atrial fibrillation is common after cardiac surgery. In this study, we aimed to investigate the value of interatrial conduction time for the prediction of early postoperative atrial fibrillation, using intra-operative transoesophageal echocardiography. METHODS A total of 65 patients undergoing cardiac surgery in our hospital(More)
In this study, the origin and course of the greater, lesser and least splanchnic nerves was investigated in 12 adult New Zealand rabbits with regard to sex and the side of the body. There were no significant differences between the female and male rabbits. The greater and lesser splanchnic nerves were present in all the cadavers examined. However, the least(More)
