AIMS: To evaluate (i) local coronary and systemic levels of microparticles (MP) in Acute Coronary Syndrome (ACS) and Stable Angina Pectoris (SAP) patients and (ii) their release after plaque disruption with percutaneous coronary intervention (PCI). BACKGROUND: Microparticles are small vesicles originating from plasma membranes of cells after activation or apoptosis and are implicated in the pathogenesis of atherosclerosis. Neutrophils play a role in plaque destabilisation and shed neutrophil-derived microparticles have the potential to drive significant pro-inflammatory and thrombotic downstream effects...

BACKGROUND: Although balloon sinus dilation is a treatment option for adults with chronic rhinosinusitis (CRS), there have been few studies performed in pediatric patients. METHODS: This study was designed as a prospective, multicenter, single-arm investigation. Children (2 to 21 years old) with CRS who had failed medical management were treated with balloon sinus dilation and followed to 6 months postprocedure. RESULTS: Fifty children were treated at 4 centers; 33 participants were 2 to 12 years old (mean ± standard deviation age: 6...

OBJECTIVE: To report upon technique of concurrent placement of angioplasty balloon at the internal jugular vein and sigmoid venous sinus junction to facilitate stent delivery in two patients in whom stent delivery past the jugular bulb was not possible. CLINICAL PRESENTATION: A 21-year-old woman and a 41-year-old woman with worsening headaches, visual obscuration or diplopia were treated for pseudotumor cerebri associated with transverse venous stenosis. Both patients had undergone primary angioplasty, which resulted in improvement in clinical symptoms followed by the recurrence of symptoms with restenosis at the site of angioplasty...

PURPOSE: Cerebral venous sinus thrombosis (CVST) is an unusual and potentially life-threatening condition with variable and nonspecific clinical symptoms and high morbimortality rates. Standard therapy consists of systemic anticoagulation; although there is no clear evidence about the best choice for treatment, intravenous heparin is used as the first-line treatment modality. Intravenous sinus thrombolysis can be an effective and relatively safe treatment for acutely deteriorating patients who have not responded to conventional therapy...

INTRODUCTION: Injuries to the internal carotid artery close to the cavernous sinus may result in a fistulous connection between the artery and the venous sinus. Symptoms include pulsatile tinnitus, intracranial bruit, ophthalmological symptoms, and risk of intracerebral hematoma in cases of cortical venous reflux. Previous treatment strategies have included detachable latex balloons, coils, covered stents, or combinations thereof. Today, detachable latex balloons are phased out or withdrawn from several markets...

Introduction: Atrial fibrillation (AF) is the most common arrhythmia in patients with mitral stenosis (MS) and it may increase complications and decreases success rates of percutaneous balloon mitral valvotomy (PBMV). This study aimed to investigate the short and long term results of PBMV in patients with AF compared to sinus rhythm (SR). Methods: In this cross sectional study, 1000 patients with MS who had undergone PBMV between 1999 and 2013 were enrolled including 585 and 415 patients with AF and SR respectively...

We report a rare causal association between obstructed supracardiac totally anomalous pulmonary venous drainage and coronary sinus ostial atresia. Our 12-week-old patient developed venous myocardial infarction secondary to coronary venous hypertension because her sole route of coronary venous drainage was obstructed. She recovered after the obstruction was relieved by balloon dilation. Surgical repair then included anastomosis of the pulmonary venous confluence to the left atrium, ligation of the vertical vein, and unroofing of the coronary sinus...

OBJECTIVE: Atrial fibrillation is the most common sustained arrhythmia in patients with rheumatic heart disease (RHD). This study was conducted to determine the maintenance of sinus rhythm with amiodarone therapy following DC cardioversion (DCCV), early after successful balloon mitral valvuloplasty (BMV). METHODS: Patients were randomized to amiodarone group and placebo group and their baseline characteristics were recorded. DCCV was done 48h after BMV. After cardioversion, oral amiodarone was started initially 200mg three times a day for 2 weeks, then 200mg twice daily for two weeks followed by 200mg once daily for 12 months...

The prognostic implications of preexisting atrial fibrillation (AF) and new-onset AF (NOAF) in transcatheter aortic valve implantation (TAVI) remain uncertain. This study assesses the epidemiology of AF in patients treated with TAVI and evaluates their outcomes according to the presence of preexisting AF or NOAF. A retrospective analysis of 708 patients undergoing TAVI from 2 heart hospitals was performed. Patients were divided into 3 study groups: sinus rhythm (n = 423), preexisting AF (n = 219), and NOAF (n = 66)...

BACKGROUND: Postoperative atrial fibrillation (AF) is a common arrhythmia that occurs after coronary artery bypass grafting (CABG). New surgical techniques, particularly off-pump coronary artery bypass (OPCAB), are thought to be less invasive and results in fewer complications, i.e. AF, but available data are inconsistent. The aim of this study is to present the incidence and risk factors of AF in patients operated on with or without cardiopulmonary bypass. METHODS: We studied 1836 consecutive patients with stable coronary artery disease who were operated on with (CABG) or without (OPCAB) cardiopulmonary bypass...

Congenitally corrected transposition of the great arteries is a rare abnormality accounting for approximately 1% of clinically apparent congenital heart disease. Age at time of diagnosis and survival rate vary and depend on associated anomalies, including pulmonary stenosis, ventricular septal defect, atrial septal defect, atrioventricular block, and atrioventricular valve regurgitation. Reported cases of corrected transposition of the great arteries with single coronary ostium anomaly and atrial septal defect are very rare...

BACKGROUND: Skull base injury is an infrequent complication during endoscopic sinus surgery (ESS). We hypothesize that late recognition and repair of CSF leaks during ESS is associated with increased neurologic morbidity. METHODOLOGY: A retrospective review was performed of patients with skull base injury during ESS at a tertiary center from 1999-2015. The study population was separated into early (less than 72 hrs) and late (more than 72 hrs) intervention groups...

Deep venous thrombosis (DVT) is a common disorder with a significant mortality rate. Successful endovascular treatment of acute DVT is most likely to be achieved in patients with recently formed thrombus, (<10-14 days) with acute iliofemoral DVT. Endovascular treatment options include: Catheter-directed thrombolysis (CDT), pharmacomechanical catheter-directed thrombolysis (PCDT), percutaneous aspiration thrombectomy (PAT), vena cava filter protection, venous balloon dilatation and venous stent implantation...

CONCLUSION: In terms of operation time, anesthesia method, and low complication rate, ESS and balloon sinuplasty seemed comparable. The advantages of balloon sinuplasty were shown to be shortness of sick leave, possibility to be performed as an in-office procedure, and lower adhesion formation. BACKGROUND: Endoscopic sinus surgery (ESS) has been considered as a treatment of choice for persistent chronic rhinosinusitis (CRS). During the last decade balloon sinuplasty has been introduced as an alternative technique to dilate the ostium...

BACKGROUND: Patients with rheumatic mitral stenosis (MS) and atrial fibrillation (AF) are at risk for thromboembolism and restoration of sinus rhythm (SR) may be the preferred strategy. Percutaneous balloon mitral valvotomy (PBMV) improves hemodynamics, but may not be enough to restore SR. METHODS: Prospective randomized study aimed at evaluating efficacy of early direct current cardioversion (DCCV) following successful PBMV in patients with long-standing AF. Group 1 (n=20) had patients of rheumatic MS with AF who underwent successful PBMV...

OBJECTIVE: Pharmacotherapy for epilepsy is limited with 30% of patients refractory to this approach of suppressing seizures. Current surgical options are invasive and carry significant morbidities including infection, bleeding, and the potential for deleterious neurocognitive effects. As a result, there is a burgeoning need for innovation to develop safer and efficacious interventions. METHODS: Four distinct catheters (2 existing: Cardima catheter, Standard EPT Blazer catheter; 2 new prototypes: balloon catheter, basket catheters) were tested in 12 baboons (21-30 kg, 100% male)...

REVIEW
Michael J Sillers, Kristopher F Lay
The decision to operate on the frontal sinus is based on persistent symptoms that have been refractory to appropriate medical therapy with associated radiographic evidence of disease by computed tomography. There is currently no evidence to support operating on radiographically negative frontal sinuses, regardless of the availability of technology or site of service options. There are many surgical procedures as well as a variety of different technologies available for the treatment of symptomatic, medically refractory frontal sinus disease...
