Acquired origin of the left anterior descending coronary artery from the pulmonary artery: A complication of the arterial switch operation

The prevalence of coronary anomalies in the transposition of the great arteries is high. Transfer of the coronary arteries during arterial switch operation is the principle step and incomplete transport of the coronary arteries to the neoaortic root results into iatrogenic coronary problems. We present a case with the residual left anterior descending coronary artery originating from the pulmonary artery as a complication of the failure of transfer during the arterial switch operation

Stent implantation in the arterial duct of the newborn with duct-dependent pulmonary circulation: single centre experience from Turkey

Implantation of stents into the ductus arteriosus is an alternative treatment to palliative or corrective cardiac surgery in newborns with duct-dependent pulmonary circulation, although the use of this technique for congenital heart disease is limited

Percutaneous Pulmonary Valve Implantation Using Edwards SAPIEN Transcatheter Heart Valve in Different Types of Conduits: Initial Results of a Single Center Experience

Background.Percutaneous pulmonary valve implantation is frequently used as a less invasive method in patients with conduit dysfunction. The common valve type cannot be used in conduits with a diameter larger than 22mm. There has been limited experience concerning the used of the SAPIEN Transcatheter Heart Valve, produced for use in conduits with a large diameter. This study presents hemodynamic and early follow-up results from a single center in Turkey concerning the use of the SAPIEN Transcatheter Heart Valve in different types of conduits and different lesions

Transcatheter Management of Neonates With Pulmonary Atresia With Intact Ventricular Septum: A Single Center Experience From Turkey

Pulmonary atresia with intact ventricular septum (PAIVS) is characterized by a broad spectrum of heterogeneous morphologies. Perforation of the atretic valve, balloon dilatation, and stenting of the patent ductus arteriosus are the percutaneous techniques that are used with increasing frequency in our clinic as well. They have some advantages over surgery, including short hospital stay and short intensive care unit stay. The main goal of the primary interventional approach is to avoid surgery. However, a group of patients with PAIVS still need surgery due to poor right ventricular growth. Therefore, the final achievement of the initial percutaneous treatment strategies is still debatable. In this article, we present the early- and mid-term results of the percutaneous approach utilized at our clinic in order to investigate the final effects of interventional therapy according to initial morphology. Between May 2010 and May 2012, 15 neonates diagnosed with PAIVS underwent transcatheter intervention. Detailed echocardiographic examination focused on right ventricle size, and tricuspid valve morphology and coronary sinusoids were performed in all the patients before the intervention. Nine of the patients were boys and six were girls. The mean age was 11.40?+/-?12.87 days and mean weight was 3.34?+/-?0.46?kg. Only one procedure-related mortality occurred. The mean follow-up period was 10.05?+/-?3.42 months (126 months). The mean duration of intensive care was 7.19?+/-?5.14 days. The mean follow-up time was 10.05?+/-?3.42 months. After this period, survival rate was 66% (10/15). Two of the patients achieved biventricular physiology after pulmonary valve perforation. Two patients still have univentricular physiology. Six patients have been followed as a one and half ventricle repair candidate. Five out of 15 patients had stent patency during 6 months of follow-up, while restenosis developed in one patient (1/5, 20%), who had undergone the Glenn operation at 5 months of age. Transcatheter management for PAIVS is a feasible, safe, and effective primary palliative treatment in newborns. Shunt surgery may be considered in cases where cyanosis occurs despite transcatheter intervention. Right ventricular size determines the type of intervention. The early outcomes can be comparable with surgical palliation. However, a group of PAIVS, particularly with severe right ventricular hypoplasia, needs surgery even after a successful primary percutaneous intervention

The importance of the neutrophil-to-lymphocyte ratio in patients with hypertrophic cardiomyopathy

Introduction: Previous studies have demonstrated the predictive value of the neutrophil-to-lymphocyte ratio (NLR) in many cardiovascular disorders. The aim of this study was to assess whether NLR is associated with echocardiographic or electrocardiographic parameters, or with predicted five-year risk of sudden cardiac death (SCD), in patients with hypertrophic cardiomyopathy (HCM)

Duration and dispersion of the P wave after the Senning operation

We studied the duration and dispersion of the P wave in patients after a Senning operation, assessing its value in detecting the risk of atrial tachycardias
