REVIEW
Ajay Kumar Jha, Neeti Makhija
Cor triatriatum is a rare congenital cardiac anomaly defined by an abnormal septation within the atrium (left or right) leading to inflow obstruction to the respective ventricles. It exists either in isolated classical form or may be associated with simple to complex congenital cardiac anomalies. Several anatomical variants exist even in the classical form, and therefore, it may require multimodal diagnostic modalities to characterize and differentiate for better percutaneous interventional or surgical planning...

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, and is associated with a fivefold increase in the risk of ischemic stroke and systemic embolism. Left atrial appendage (LAA) is the source of thrombi in up to 90% of patients with nonvalvular atrial fibrillation (AF). Although thromboembolic prophylaxis by means of oral anticoagulants (OAC) has been shown to be very effective (OAC), they also confer an inevitably risk of serious bleeding. Catheter ablation (CA) is an effective treatment for symptomatic AF but its role in stroke prevention remains unproved...

Biliary disease in infants and children frequently presents diagnostic and therapeutic challenges. Pediatric interventional radiologists are often involved in the multidisciplinary teams who care for these patients. This article reviews several notable causes of biliary disease in children who have not undergone liver transplantation, describes the role of percutaneous interventional procedures in managing these conditions, and details applicable biliary interventional techniques.

Clinical data such as history, physical examination, and laboratory tests are useful in identifying patients with biliary obstruction and biliary sources of infection. However, if intervention is planned, noninvasive imaging is needed to confirm the presence, location, and extent of the disease process. Currently, the most commonly available and used noninvasive modalities are ultrasound (US), computed tomography (CT), magnetic resonance (MR), and nuclear medicine hepatobiliary scintigraphy (HIDA). US is quick, portable, readily available, and is commonly the first imaging modality used when biliary pathology is suspected...

Poor data exist about predictors of long-term cardiac mortality in patients presenting acute myocardial infarction (AMI) complicated by cardiogenic shock (CS) treated with primary percutaneous coronary intervention (p-PCI), and current risk-adjustment models in this setting are not adequate. We retrospectively analyzed our registry of patients with AMI treated with p-PCI. The aim of this study was to identify the independent predictors of 2-year cardiac mortality in patients presenting CS. A Risk Score was created assigning at any independent variable a value directly correlated with its power to increase mortality...

BACKGROUND: The CvLPRIT study showed a trend for improved clinical outcomes in the complete revascularisation (CR) group in those treated with an immediate, as opposed to staged in-hospital approach in patients with multivessel coronary disease undergoing primary percutaneous intervention (PPCI). We aimed to assess infarct size and left ventricular function in patients undergoing immediate compared with staged CR for multivessel disease at PPCI. METHODS: The Cardiovascular Magnetic Resonance (CMR) substudy of CvLPRIT was a multicentre, prospective, randomized, open label, blinded endpoint trial in PPCI patients with multivessel disease...

INTRODUCTION: Patients with chronic refractory angina whose symptoms are not controlled with conventional therapies have a poor quality of life. Adjunctive therapies, such as spinal cord stimulation (SCS) may be considered in these cases. We sought to examine whether SCS is associated with changes in exercise capacity and angina severity in these patients. METHODS: We searched Pubmed, Medline and other databases until December 2015. Two reviewers independently extracted data and assessed risk of bias...

Percutaneous intervention is preferred over reoperation for the treatment of iatrogenic membranous ventricular septal defects (VSDs). During the standard percutaneous procedure, an arterio-venous loop is used for occluder deployment, entailing the risk of device impingement on the prosthetic aortic valve, which may cause serious complications or even death. In this report, we describe a novel non-prosthesis touching procedure for the closure of a VSD in a patient with prior aortic valve replacement. The unique feature of this technique is the use of an apex-venous loop for occluder deployment, which prevents the device impingement on the prosthetic valve, thus avoiding difficulties, lengthy operation and serious complications associated with the standard procedure...

BACKGROUND AND AIMS: To improve treatment success of ST-elevation myocardial infarction, a minimal delay from symptom onset to reperfusion therapy is crucial. The patient's response to initial symptoms (patient delay) substantially affects the delay. We investigated time patterns of patient delay during a seven-year time period, and aimed to identify key predictors that affect the length of the patient delay. METHODS: Data on 5848 patients hospitalized with ST-elevation myocardial infarction and treated with primary percutaneous intervention during the period 2003-2009 were obtained from Danish registry databases...

BACKGROUND: Chronic total occlusion percutaneous coronary intervention (CTO-PCI) can improve angina and left ventricular ejection fraction (LVEF). These benefits were not assessed in populations with heart failure with reduced ejection fraction (HFrEF). We studied the effect of CTO-PCI on left ventricular function and clinical parameters in patients with HFrEF. METHODS: Using cardiovascular magnetic resonance (CMR), we studied 29 patients with HFrEF and evidence of viability and/or ischemia in the territory supplied by a CTO who were successfully treated with CTO-PCI...

Primary percutaneous transluminal coronary angioplasty (PTCA) with the insertion of a stent is a well-established procedure for management of coronary artery disease. Infected pseudoaneurysms following PTCA and stenting are very rare and have poor outcomes if not managed properly. We are presenting a case of a man aged 50 years with infected pseudoaneurysm of the left anterior descending artery following multiple percutaneous interventions for coronary artery disease. In this paper, we have described the presentation, diagnosis and management of this patient and have discussed the aetiology and management options of infected pseudoaneurysm affecting coronary arteries...

INTRODUCTION: Cardiac inflammatory myofibroblastic tumor is a rare tumor that can cause potentially fatal outcomes. CASE PRESENTATION: We describe a case where the tumor originated on the mitral valve and extended through the left ventricular outflow tract and aortic valve and into the left main artery obstructing it. Due to the hemodynamic instability of the patient, we proceeded for cardiac catheterization with the intention to aspirate the mass but were forced to do percutaneous intervention to stabilize the patient and bridge him to surgery...

The aim of the study was to investigate the BiCx after the pediatric OLT and to assess the efficacy of the fluoroscopic-guided PBI in the patients with BiCx as compared to the SR. A total of 340 OLTs were performed in 302 patients over the last 16 years. The inclusion criteria were the presence of BS or BL as a complication after OLT. The management of the BiCx was studied. Graft revision, graft loss, and survival were evaluated following PBI and SR. BiCx occurred in 17.1% (58/339) of the transplants; 6.2% (21/339) of transplants demonstrated BL and 12...

INTRODUCTION: A radiocephalic arteriovenous fistula (AVF) is the best choice for achieving vascular access (VA) for hemodialysis, but this AVF has high rates of early failure due to juxta-anastomotic stenosis, making it impossible to use for dialysis. Low hemodynamic shear stress contributes to the pathophysiology of VA failure due to secondary thrombosis, stenosis, and re-occlusion after percutaneous intervention. METHODS: We used a computational fluid dynamics (CFDs) approach to evaluate the shear stress distribution and minimize its effects under various conditions including changes in the anastomosis angle...

PURPOSE: An intraluminal coronary stent is a metal mesh tube deployed in a stenotic artery during percutaneous coronary intervention (PCI), in order to prevent acute vessel occlusion. The identification of struts location and the definition of the stent shape is relevant for PCI planning and for patient follow-up. The authors present a fully automatic framework for computer-aided detection (CAD) of intracoronary stents in intravascular ultrasound (IVUS) image sequences. The CAD system is able to detect stent struts and estimate the stent shape...

PURPOSE: Percutaneous ablation under MRI-guidance allows treating otherwise inoperable liver tumors locally using a catheter probe. However, manually placing the probe is an error-prone and time consuming task that requires a considerable amount of training. The aim of this paper was to present a pneumatically actuated robotic instrument that can assist clinicians in MRI-guided percutaneous intervention of the liver and to assess its functionality in a clinical setting. The robot positions a needle-guide inside the MRI scanner bore and assists manual needle insertions outside the bore...

A 44-year-old woman, who had had left flank pain for the previous 3 months, was treated successfully for renal hydatid cyst disease by using an endoscopic technique with percutaneous access through an all seeing needle. Abdominal ultrasonography showed a Gharbi type III cyst in the lower pole of the left kidney. Computerised tomography of the abdomen revealed a bulky solid-cystic mass with calcified and well-defined wall and daughter cyst without contrast enhancement. The patient, who refused any renal operation, underwent a percutaneous intervention with access through an all seeing needle access...
