PURPOSE: The atrial transseptal procedure is used in catheter ablation of left-sided arrhythmias. Studies in adult patients have shown the SafeSept™ transseptal guidewire (SSTG) to be effective in atrial transseptal procedures. We analyzed our 5-year experience with SSTG use in pediatric and congenital heart disease patients undergoing catheter ablation. METHODS: This is a single-center retrospective analysis of patients undergoing catheter ablation from 2009 to 2014...

We have previously reported that pulmonary artery endothelial cells (PAECs) can be harvested from the tips of discarded Swan-Ganz catheters after right heart catheterization (RHC). In this study, we tested the hypothesis that the existence of an antiapoptotic phenotype in PAECs obtained during RHC is a distinctive feature of pulmonary arterial hypertension (PAH; World Health Organization group 1) and might be used to differentiate PAH from other etiologies of pulmonary hypertension. Specifically, we developed a flow cytometry-based measure of Bcl-2 activity, referred to as the normalized endothelial Bcl-2 index (NEBI)...

Patients with pulmonary arterial hypertension (PAH) often require parenteral prostanoids to improve symptoms and signs of PAH. Complications of parenteral prostanoids-such as catheter-related infections and intolerable adverse effects-may develop, prompting transition to inhaled prostanoids. We report a prospective, protocol-driven transition from parenteral prostanoids to inhaled prostanoids with monitoring of exercise gas exchange and acute hemodynamics. Three PAH centers recruited patients transitioning from parenteral prostanoids to inhaled trepostinil...

BACKGROUND: The accuracy of currently available devices using pulse contour analysis without external calibration for cardiac index (CI) estimation is negatively impacted by hyperdynamic states, low systemic vascular resistance (SVR), and abrupt changes in SVR. The aim of this study was to evaluate the accuracy of a new device, the Pulsioflex (Pulsion Medical System), in patients undergoing liver transplantation. METHODS: Thirty consecutive patients scheduled for liver transplantation were included...

BACKGROUND: Transesophageal echocardiography (TEE) is increasingly replacing thermodilution pulmonary artery catheters to assess hemodynamics in patients at high risk for cardiovascular morbidity. However, one of the drawbacks of TEE compared to pulmonary artery catheters is the inability to measure real time stroke volume (SV) and cardiac output (CO) continuously. The aim of the present proof of concept study was to validate a novel method of SV estimation, based on pulse wave velocity (PWV) in patients undergoing cardiac surgery...

Totally implanted port devices are important for the administration of fluid and chemotherapeutic agents. However, their use may be associated with serious complications, such as catheter fracture and embolism. Most data on port catheter embolization consist of isolated case reports. We report a 6-year-old boy with relapse of an acute lymphoblastic leukemia. He presented with dysfunction of his totally implanted port device. Radiologic examination revealed a catheter fracture. Echocardiography showed the catheter embolized into the right ventricle...

PURPOSE: During the process of tracheal intubation, patients are apneic or hypoventilating and are at risk of becoming hypoxemic. This risk is especially high in patients with acute or chronic respiratory failure and accompanying compromised respiratory reserve. To address this concern, apneic oxygenation can be administered during tracheal intubation to aid in maintaining arterial oxygen saturation. The objective of this narrative review is to examine the utilization of apneic oxygenation within the operating room, intensive care unit (ICU), emergency department, and pre-hospital settings and to determine its efficacy compared with controls...

A 76-year-old male presented with a submassive pulmonary embolism despite having an inferior vena cava (IVC) filter. Imaging demonstrated pulmonary artery emboli and a deep vein thrombosis in the left common femoral vein. Venography revealed the IVC filter with struts extending into the left and right renal veins. A new IVC filter was deployed below the prior filter. This case demonstrates IVC filter migration complicated by a submassive pulmonary embolism.

REVIEW
X Watson, M Cecconi
Over recent years there has been an increase in the implementation of goal-directed therapy using minimally invasive haemodynamic monitoring techniques to guide peri-operative care. Since the introduction of the pulmonary artery flotation catheter in the 1980s, various haemodynamic monitors have been developed, each associated with their own benefits and limitations. Goal-directed therapy has been well-established as a standard of care in the peri-operative period and has largely been associated with a reduction in morbidity and mortality...

Interventional cardiac catheterization has a major place in the management of congenital heart disease. Since the Rashkind atrioseptostomy in mid-1960s, many techniques have been developed. For some, it is necessary to close a cardiac or extracardiac shunt using occluder (double disc system, plug, coil…): closure of atrial septal defect, ventricular septal defect or patent arterial duct. For others, it is necessary to treat a valvular or vascular stenosis using a balloon catheter: dilatation of the pulmonary or the aortic valve, dilatation of aortic coarctation...

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is a disease characterized by chronic obstructive thrombus and pulmonary hypertension. Balloon pulmonary angioplasty (BPA), an emerging alternative catheter-based treatment for inoperable patients with CTEPH, has not yet been standardised, especially for lesion assessment in distal pulmonary arteries. Recent advancement in computed tomography enables distal CTEPH lesions to be visualized. METHODS: We retrospectively studied 80 consecutive patients with inoperable CTEPH who received BPA guided by cone-beam computed tomography (CT) (CBCT) or electrocardiogram (ECG)-gated area detector CT (ADCT) for target lesion assessment...

INTRODUCTION: Cardiac migration of ventriculoperitoneal (VP) shunts has been reported, with most easily removed or shortened via a cervical incision. We present a review of the literature, highlighting our unique case with significant scarring requiring open, on-pump, cardiac surgery for removal of migrated distal tubing. CASE PRESENTATION: A 7-year-old boy underwent VP shunt insertion for hydrocephalus secondary to intracranial astrocytoma. He presented at age 17 with evidence of right heart strain, associated with the distal shunt catheter proximally migrated into his heart and pulmonary arteries...

A 50's underwent gastrectomy for gastric cancer 4 years before. He had received chemotherapy for para-aortic lymph node metastases. A central venous catheter with a subcutaneous port was implanted via the right subclavian vein, under ultrasonographic guidance, 1 year 3 months earlier. The patient complained of swelling in his right chest during intravenous injection of ramucirumab and paclitaxel via the port. A chest radiograph revealed that a catheter fracture. A CT scan showed that the fractured catheter had lacerated the pectoralis minor muscle and the tip was in the right inferior pulmonary artery...

Few inventions in modern medicine have generated as passionate and extended debate as the pulmonary artery catheter (PAC). Since its introduction in 1970, the PAC remains an indispensable monitor in cardiovascular critical care. Despite attempts to develop less invasive alternatives, the PAC remains unequaled as a single monitoring device capable of measuring physiological derangement in most components of the circulation, in the awake or sedated patient, with real-time feedback on the efficacy of an intervention...
