BACKGROUND: Introduced in 1970, the Swan-Ganz catheter (SGC) soon became widely used because of its unique usefulness in managing intensive care patients. Unfortunately, SGC usage was complicated by pulmonary artery rupture (PAR) with a 50% mortality rate that led to a near banning of the SCG in the late 1980s. Increasing knowledge and decreasing incidence of SGC-related PARs (SGPARs) led to the current feeling that the present SGPAR incidence is now low enough to tolerate given the lives saved by SGC usage...

Redo cardiac surgery in patients with severe aortic insufficiency can present unique challenges to the anesthesiologist. We report a case highlighting the challenge and importance of interdisciplinary planning between cardiothoracic surgeons and anesthesiologists prior to high-risk surgery. Failure to place an endoaortic balloon and percutaneous coronary sinus catheter due to anatomical abnormalities prompted the adoption of an alternate technique involving apical ventricular venting to assist sternal reentry...

OBJECTIVE: Surgery for uterine cervical fibroids is difficult because of restricted surgical access and risks such as intraoperative bleeding or injury to other organs. The internal iliac artery balloon occlusion catheter (IIABOC) provides effective hemostasis for placenta previa and atonic hemorrhage, and is increasingly used in surgery for uterine fibroids for controlling intraoperative hemorrhage. We investigated the efficacy and safety of the IIABOC for controlling intraoperative bleeding in total abdominal hysterectomies (TAH) and abdominal myomectomies (AM) for large cervical fibroids...

Balloon uncrossable lesions are a well-known challenge during chronic total occlusion (CTO) interventions. The technique of using two different catheters into the same coronary artery, the so-called "ping-pong" technique, is a technique described for treating complications during percutaneous coronary intervention (PCI), like perforations or rotational atherectomy burr entrapment. We describe a case where the "ping-pong" technique was successfully used to facilitate treatment of a balloon uncrossable CTO lesion...

OBJECTIVE: Balloon Sinuplasty for the management of paranasal sinus inflammatory diseases was introduced in otolaryngology in 2005. Over the past decade, evidence strongly supports its safety and efficacy for the treatment of chronic rhinosinusitis (CRS) in adults. Because it requires no bone or tissue removal, this procedure could be suitable in children. We present our initial experience of its use for the treatment of CRS in children. MATERIALS AND METHODS: A prospective study was performed of 30 children with failed medical therapy, who were scheduled for surgery...

INTRODUCTION: One question for the technological advancement of catheter ablation of atrial fibrillation (AF) is whether a creative new concept can combine and even improve the diagnostic mapping options of single-tip and basket catheters with the simplicity of the use of balloon catheters for ablation. Herein, we describe the first in-human experience with a single catheter offering such a complete solution. METHODS AND RESULTS: A new catheter (Globe®) with a distal multi-electrode array consisting of 16 ribs with 122 gold-plated electrodes was used...

The SLENDER Integrated Delivery System (IDS™) is an 'all-in-one' fixed-wire coronary stenting device designed for direct stenting, precluding the need for conventional guidewires and predilatation balloons. It achieves ultra-low profiles (crossing profiles as low as 0.029" /0.737 mm), enabling the downsizing of catheters to facilitate TRI across wider subsets of patients. Areas covered: This paper aims to evaluate the SLENDER IDS for the treatment of coronary artery disease. Expert commentary: The system represents the first advance in coronary stent delivery since the introduction of rapid-exchange stent delivery systems more than 20 years ago and is a new...

BACKGROUND AND AIMS: Endoscopy has replaced many radiological studies for the GI tract. However, ERCP remains a hybrid endoscopic-fluoroscopic procedure, which limits its portable delivery, creates delays due to fluoroscopy room unavailability and exposes patients/providers to radiation. We evaluated fluoroscopy/radiation-free management of patients with non-complex choledocholithiasis using direct solitary cholangioscopy (DSC). METHODS: Patients underwent fluoroscopy-free biliary cannulation, sphincterotomy then cholangioscopy to establish location, number/size of stones and document distance from ampulla to bifurcation to guide balloon advancement...

INTRODUCTION: Therapy of malignant pleural mesothelioma and especially the adequate role of surgery in this context remain the subject of controversial discussions. Radical surgery in particular, which is associated with substantial morbidity, failed to translate into a definite survival advantage. We report on interim results of an ongoing Phase II study of regional chemotherapy in terms of isolated thoracic perfusion with chemofiltration (ITP-F). PATIENTS AND METHODS: Twenty-eight patients (25 male, 3 female, mean age 63...

Not infrequently, interventionalists are faced with a patient with increased blood pressure who is about to undergo a dialysis access intervention such as tunneled hemodialysis catheter, percutaneous balloon angioplasty, or declotting procedure for a clotted arteriovenous access. This can frequently create a dilemma as functional dialysis access is needed to provide dialysis therapy and delaying treatment could result in a life-threatening situation, particularly in the presence of hyperkalemia. This article investigates hypertension in patients undergoing percutaneous dialysis access interventions and provides guidance to their management...

BACKGROUND: Esophageal pressure, used as a surrogate for pleural pressure, is commonly measured by air-filled balloon, and the accuracy of measurement depends on the proper balloon volume. It has been found that larger filling volume is required at higher surrounding pressure. In the present study, we determined the balloon pressure-volume relationship in a bench model simulating the pleural cavity during controlled ventilation. The aim was to confirm whether an optimal balloon volume range existed that could provide accurate measurement at both end-expiration and end-inspiration...

A 69 year old male, with a previous percutaneous revascularization of the mid-circumflex with a bare metal stent in 2007 was admitted to our centre for unstable angina. The angiography showed a severely calcified coronary tree with a functionally severe plaque on the proximal left anterior descending artery (LAD) and a critical focal lesion on the proximal right coronary artery. After a high pressure predilation on the proximal LAD, the balloon ruptured causing a retrograde LAD-left main (LM) dissection that was rapidly sealed with three overlapping zotarolimus-eluting stents from medial LAD to LM...

BACKGROUND: Auxetics, a special class of materials, tend to expand both in the radial and longitudinal directions when a unidirectional tensile force is applied. Recently, studies have come up with new designs for auxetic vascular and nonvascular stents which are deployed with commercial balloon catheters. There are some inherent limitations associated with a unidirectional application of expansion force in the effective deployment of stents. This work proposed a solution to some of these limitations through the use of a biaxial mode of a predetermined strain-based expansion mechanism...
