A Randomized, Double-Blind, Placebo-Controlled, Clinical Trial of High-Dose, Short-Term Vitamin D Administration in the Prevention of Acute Kidney Injury after Cardiac Surgery.

Background: Acute kidney injury (AKI) after cardiac surgery is a relatively common complication affecting short- and long-term survival. The renoprotective effect of vitamin D (VitD) has been confirmed in several experimental models. This study was conducted to evaluate the effect of high-dose VitD administration in patients with VitD insufficiency on the incidence of postoperative AKI, the urinary level of tubular biomarkers, and serum anti-inflammatory biomarker after coronary artery bypass graft.

Vitamin D Treatment Attenuates Heart Apoptosis After Coronary Artery Bypass Surgery: A Double-Blind, Randomized, Placebo-Controlled Clinical Trial.

Background: Vitamin D plays an important role in immune system and in the regulation of inflammatory cytokines. Coronary artery bypass graft (CABG) with cardiopulmonary bypass (CPB) is associated with an extensive inflammatory response. The aim of this study is to examine the effect of vitamin D treatment on the apoptosis and inflammatory changes developed after CABG.

Huge aneurysmal fistula from left main artery to right atrium in a man with atypical chest pain and dyspnea on exertion.

We present a 33-year-old man with atypical chest pain and with no significant past medical history. The patient was finally diagnosed as a case of huge fistula from the left main coronary artery to the right atrium, a very rare condition with challenging diagnostic and therapeutic approaches. The majority of cases of coronary artery fistula are small, asymptomatic and clinically undetectable; they frequently do not cause any complications and can spontaneously resolve.

Left Atrial Drainage of the Right Superior Vena Cava: A Case Report.

An isolated right superior vena cava (RSVC) draining into the left atrium represents a very rare congenital malformation, especially in the absence of a partial anomalous pulmonary venous return. This condition leads to hypoxemia, cyanosis, and clubbing without any other signs of heart defects. We describe an 8-year-old girl, who was referred to our hospital due to unexplained cyanosis.

The Dilemma in Treatment of hemodialysis patients with catheter-induced right atrial thrombi (CRAT): A case report.

Catheter-induced right atrial thrombi (CRAT) is a serious complication of central venous catheterization. Herein we report a case of large hypermobile right atrial thrombi in a 57-year-old man with hemodialysis catheter in the right internal jugular vein.

An investigation of the rate of cyclooxygenase-2 expression on the surface of adenomatous and colorectal adenocarcinoma polyps.

Background: Colorectal cancer (CRC) (adenomatous, adenocarcinoma) is one of the major causes of mortality and morbidity in human societies. Considering the importance of cyclooxygenase-2 (COX-2) expression in the incidence of CRC, in this study, the rate of COX-2 gene expression on polyps and CRCs were addressed.

Materials And Methods: This is a cross-sectional descriptive analytic study carried out on the blocks of sampled tissue of adenomatous and colorectal adenocarcinoma polyps on 68 patients referred to Digestive Clinic in Isfahan Shariati Hospital in 2013.

Enzyme Polymorphism in Warfarin Dose Management After Pediatric Cardiac Surgery.

Background: Warfarin is an anticoagulant and is widely used for the prevention of thromboembolic events. Genetic variants of the enzymes that metabolize warfarin, i.e.

Early and Mid-Term Outcome of Pediatric Congenital Mitral Valve Surgery.

Background: Congenital lesions of the mitral valve are relatively rare and are associated with a wide spectrum of cardiac malformations. The surgical management of congenital mitral valve malformations has been a great challenge.

Objectives: The aim of this study was to evaluate the early and intermediate-term outcome of congenital mitral valve (MV) surgery in children and to identify the predictors for poor postoperative outcomes and death.

Effect of obesity on mortality and morbidity after coronary artery bypass grafting surgery in Iranian patients.

Background: Recent years have witnessed the emergence of obesity as a major public health concern. The drastic rise in obesity and its concomitant co-morbidities is a reflection of the recent changes in dietary habits in Iran and many other developing countries. A recent large population study in Tehran reported that 58% and 75% of middle-aged Iranian men and women, respectively, were either overweight or obese.

Left pulmonary artery stenting with glenn shunt: introducing a hybrid procedure.

Complexity of some congenital heart diseases sometimes necessitates a combination of interventional procedures and surgery, amongst which intraoperative stent implantation is one of the most common. We herein report a successful hybrid procedure in a cyanotic adult patient who had undergone no procedure in childhood. The patient was a 24-year-old cyanotic male (oxygen saturation in the room air was 65%) who presented with dyspnea.

An unusual right atrial mass in a two-month old infant.

We report a 2-month old female with a rare cardiac mass. She was evaluated echocardiographically after physical examination revealed a low grade cardiac murmur. The mass, located in right atrium, was shown to be the consequence of candida endocarditis by means of pathological study and blood culture.
