Intravascular Ultrasound Balloon Catheter
Background Coronary stenting in conjunction with coronary angioplasty is a valuable tool for treatment of severe coronary dissection and is effective in reducing the frequency of restenoses. Evidence is increasing that the lumen gain within the stent is negatively correlated with the rate of subacute closures and restenoses. Since the assessment of radiolucent coronary stents and complex lumen ...
متن کاملA technique for unknotting an intracardiac flow-directed balloon catheter.
Described is an unusual complication occurring during right-sided cardiac catheterization using a 7F flow-directed balloon catheter. During an attempt to direct the catheter from the main pulmonary artery into the pulmonary wedge position, the tip became entangled in a loop of catheter and knotted. Initially, all attempts to unknot or remove the catheter failed. A movable core guide wire was pa...
متن کاملIntravascular and Intracardiac Ultrasound Imaging
C onsiderable attention is currently being focused on the development of intravascular and intracardiac ultrasound imaging.1-4 Variously termed as "ultrasound angioscopy," "intravascular ultrasound imaging," or "intraluminal ultrasound imaging," this technique basically refers to the imaging modality of visualizing blood vessels and cardiac structures by an ultrasound transducer placed at the t...
متن کاملIntracardiac echocardiography--guided percutaneous mitral balloon valvuloplasty.
Percutaneous mitral balloon valvuloplasty (PMBV) was initially described by Inoue in 1984 as a novel percutaneous technique for the management of mitral stenosis. Intracardiac echocardiography was initially used in the 1980s but was not universally accepted due to its high-frequency transducers and problems with steerability and manipulation. In the 1990s technical improvements led to more gene...
متن کاملUtility of intracardiac ultrasound imaging to guide pulmonary vein ablation using laser balloon catheter.
BACKGROUND Pulmonary vein isolation (PVI) with balloon catheter has been used as the endpoint for AF ablation. OBJECTIVE To determine the usefulness of intracardiac ultrasound (ICUS) to guide PVI using laser balloon catheter. METHODS 59 PVs were ablated in 27 dogs. Doppler imaging was used to identify blood flow leaks between PV and balloon. After each energy delivery, the circular mapping ...
