Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a very rare congenital heart defect. Herein, we describe three cases of ARCAPA in an 8 months old, 18 months old, and 4 year old child. Two cases were incidentally diagnosed using a computed tomographic angiograph, and the other was incidentally diagnosed using a coronary angiograph. These cases underwent a reimplantation technique on diagnosis and resulting in positive clinical outcomes during the follow-up period which was a mean of 1...

A patient was admitted for catheter ablation of atrial fibrillation. Cardiac computed tomography and transesophageal echocardiography revealed the absence of the left atrial appendage. However, the right atrial appendage looked normal and the level of pro B-natriuretic peptide was within normal limits. Successful catheter ablation was performed without any procedural complications and the sinus rhythm was appropriately maintained for 10 months with an antiarrhythmic drug.

65-year-old woman was admitted to our hospital with acute decompensated heart failure with reduced left ventricular ejection fraction and severe mitral regurgitation. Electrocardiography revealed a typical left bundle branch block and atrial fibrillation. Her condition deteriorated despite administering high-doses of inotropes and vasopressors. Pending a decision to therapy, venoarterial extracorporeal membrane oxygenation (ECMO) was performed when the patient underwent a cardiogenic shock. Although the hemodynamic status stabilized with ECMO support, weaning the patient from ECMO was not possible...

BACKGROUND AND OBJECTIVES: Hyaluronic acid (HA) is highly biocompatible with cells and the extracellular matrix. In contrast to degradation products of a synthetic polymer, degradation products of HA do not acidify the local environment. The aim of this study was to fabricate an HA-coated paclitaxel (PTX)-eluting stent via simple ionic interactions and to evaluate its effects in vitro and in vivo. MATERIALS AND METHODS: HA and catechol were conjugated by means of an activation agent, and then the stent was immersed in this solution (resulting in a HA-coated stent)...

BACKGROUND AND OBJECTIVES: Subintimal angioplasty is a common treatment choice for chronic total occlusions (CTO) in the iliac and femoropopliteal arteries. This article describes the technical aspects and early outcomes of two different re-entry devices and comparison with manual re-entry technique. SUBJECTS AND METHODS: A retrospective review of 61 patients (re-entry group) treated with Outback or Pioneer Plus catheters was carried out. A matched cohort of patients (n=62) who underwent lower extremity interventions without the use of re-entry devices (manual re-entry group) were also analyzed (overall 123 patients were analyzed)...

BACKGROUND AND OBJECTIVES: Prior studies indicate that up to 35% of cases of severe aortic stenosis (AS) have paradoxical low flow, low gradient despite preserved left ventricular ejection fraction (LVEF). However, error in left ventricular outflow tract (LVOT) diameter may lead to misclassification. Herein, we determined whether measurement of LVOT diameter by transesophageal echocardiography (TEE) results in reclassification of cases to non-severe AS. SUBJECTS AND METHODS: Patients with severe AS with aortic valve area (AVA) <1 cm(2) by transthoracic echocardiography (TTE) within 6 months were studied...

BACKGROUND AND OBJECTIVES: Hemodynamically unstable idiopathic ventricular tachycardias (VTs) are a challenge for activation or entrainment mapping technique. Mechanical circulatory support is an option, but is not always readily available. In this study, we investigated the safety and efficacy of hemodynamic support using intravenous (IV) dopamine solely during radiofrequency catheter ablation (RFCA) of hemodynamically unstable VT. SUBJECTS AND METHODS: Seven out of 86 patients with hemodynamically unstable idiopathic VT underwent de novo RFCA using dopamine in our single center...
