OBJECTIVES The goal of this study was to describe the clinical outcomes of patients undergoing cardiac catheterization while supported with extracorporeal membrane oxygenation (ECMO). BACKGROUND Extracorporeal membrane oxygenation is an important mechanical support for the failing circulation. There are diagnostic and therapeutic indications for cardiac catheterization in patients on ECMO, bu...

BACKGROUND Radial artery catheterization is associated with endothelial denudation and impaired vasodilator function, while postcatheterization exercise training may enhance artery function. The impact of catheterization and subsequent exercise training on low-flow mediated vasoconstriction (L-FMC) has not previously been studied. The aim of this study was to examine whether radial artery L-FMC...

BACKGROUND In patients with complex pulmonary stenosis or atresia, a detailed delineation of all sources of pulmonary blood supply is necessary for planning surgical and transcatheter procedures and usually requires diagnostic cardiac catheterization. The goals of this study were to determine whether gadolinium-enhanced 3D magnetic resonance angiography (MRA) can provide a noninvasive alternati...

Complete atrioventricular block (CAVB) during cardiac catheterization is a rare complication. We describe a patient with preexisting complete right bundle branch block who developed CAVB during left-sided cardiac catheterization. CAVB was induced when a left-sided catheter was passed through the aortic valve. We speculate that the patient's His bundle was injured by mechanical compression. Phys...

Background MRI-guidance of cardiovascular catheterization offers improved soft-tissue contrast and reduced ionizing radiation exposure. The application of MRI-guidance to complex catheterization procedures has been limited by the unavailability of guidewires that are safe and visible under MRI. Here, we use RF-efficient spiral imaging for MR-guided cardiovascular catheterization, with real-time...

neous method of right and left heart catheterization was used in 127 patients. In infants and children weighing more than 10 pounds, the percutaneous method was found to be an effective technic associated with a 3% incidence of diminished arterial pulses in the catheterized limb. All patients in this weight group, except one, had left heart catheterization by this technic. The method was deemed...

The infectious complications that occur following vascular access for catheterization are frequently associated with an unfavourable outcome, mainly because diagnosis is delayed. Although its incidence is low, clinicians should be aware of this complication as the use of invasive procedures is increasing. Here, we report our experience with five patients.

BACKGROUND Untreated postoperative urinary retention can result in permanent lower urinary tract dysfunction and can be prevented by timely bladder catheterization. The author hypothesized that the incidence of postoperative bladder catheterization can be decreased by using the patient's own maximum bladder capacity (MBC) instead of a fixed bladder volume of 500 ml as a threshold for catheteriz...

OBJECTIVE To evaluate whether nitrofurantoin prophylaxis prevents postoperative urinary tract infection (UTI) in patients receiving transurethral catheterization after pelvic reconstructive surgery. METHODS In a randomized, double-blind, placebo-controlled trial, participants undergoing pelvic reconstructive surgery were randomized to 100 mg nitrofurantoin or placebo once daily during cathete...

Introduction: Arteriovenous malformations (AVMs) are uncommon vascular lesions that can arise in any part of the body. Case Report: In this case study, we presented a huge AVM of the upper lip in a 70-year-old man that he noticed since 5years ago with slow growth in this period. Computed tomography angiography revealed a large AVM with feeders from the right...
