• angiography
  • Reference diameter, minimal lumen diameter, and percent diameter stenosis (DS) were measured by quantitative coronary angiography. (ahajournals.org)

  • Angiography of the contralateral artery was performed during balloon coronary occlusion in 105 patients with single-vessel disease (left anterior descending coronary artery in 69 patients, left circumflex coronary artery in 4 patients, right coronary artery in 32 patients) and normal left ventricular function. (onlinejacc.org)
  • A new study presented at the EuroPCR 2013 reveals that measuring fractional flow reserve (FFR) with the help of pressure wire assessment during coronary angiography for diagnosis of chest pain can provide significant changes in the management of almost quarter of the patients. (medindia.net)
  • The RIPCORD (Does routine pressure wire assessment influence management strategy at coronary angiography for diagnosis of chest pain) study was designed to assess whether routine assessment of FFR in all the main coronary branches would significantly change the management strategy derived from diagnostic angiography alone. (medindia.net)
  • They all underwent diagnostic coronary angiography carried out by one cardiologist who used the results to develop a treatment plan (plan 1) giving recommendations for medical treatment, percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) or to request more information. (medindia.net)
  • Routine use of FFR at diagnostic coronary angiography resulted in a significant change in management in 26% of patients," Curzen reported. (medindia.net)
  • Commenting on the implications of the study findings, Kari Niemela, Medical Director and founder of the Heart Center Co., Tampere University Hospital, Tampere, Finland, said, "The RIPCORD trial demonstrated that routine measurement of FFR in patients with stable angina pectoris changes treatment plan in one out of four patients as compared to visual evaluation with coronary angiography alone.

  • Cardiac catheterization" is a general term for a group of procedures that are performed using this method, such as coronary angiography and left ventricle angiography. (wikipedia.org)
  • They are rarely if ever observed during angiography in the absence of severe ischemia (vessels less than 200 micrometers are not visible, generally), and only coronary stenosis, anemia, and exercise have experimentally been shown to cause transformation. (wikipedia.org)
  • acute
  • 1M coronary catheterizations Recent successes in acute stroke care are driving the need for every stroke center to perform endovascular reperfusion interventions. (wikipedia.org)
  • occlusion
  • Ischemia during coronary occlusion was evaluated by the ST segment shift (mV) in a 12-lead electrocardiogram (ECG). (onlinejacc.org)
  • Coronary angioplasty serves as a model to study the collateral circulation in a controlled fashion during abrupt coronary balloon occlusion ( [2-). (onlinejacc.org)
  • There are two major categories of cardiac catheterization: Left heart catheterization allows for direct intervention in cases of coronary artery occlusion. (wikipedia.org)
  • This technique is also used to assess the amount of occlusion (or blockage) in a coronary artery, often described as a percentage of occlusion. (wikipedia.org)
  • Occlusive aortography involved the transient occlusion of the aorta and subsequent injection of a small amount of radiographic contrast agent into the aortic root and subsequent serial x-rays to visualize the coronary arteries. (wikipedia.org)
  • Most observers agree that a 90% occlusion is necessary to bring about transformation in the absence of other factors, though a recent article suggests that they may appear as a result of coronary spasm in the absence of total occlusion (see below). (wikipedia.org)
  • vessels
  • Coronary heart diseases are caused due to the narrowing of the heart vessels, which supply blood and oxygen to the heart muscles, thus keeping heart muscles alive. (heart-disease-treatments.com)
  • Randomized Trial of Coronary Angioplasty for de Novo Lesions in sMall vesSElS With Drug Eluting Balloon. (clinicaltrials.gov)
  • The current study has been designed to know, in one hand, the clinical efficacy of the Drug elluting balloon IN.PACT FALCON and, in other hand, the effectiveness, and the cost-effectiveness incremental analysis of DEBs (IN.PACT FALCON vs. DES ( RESOLUTE INTEGRITY) in patients with de novo lesions in small vessels. (clinicaltrials.gov)
  • The coronary arteries are known as "epicardial vessels" as they are located in the epicardium, the outermost layer of the heart. (wikipedia.org)
  • The functional significance of the coronary collateral vessels is a matter of continuing experimental investigation although their existence has been known for over three centuries and been documented repeatedly in man and beast over the past seven decades. (wikipedia.org)
  • This leads to attraction and activation of monocytes and T-cells into the adventitial space (peripheral collateral vessels) or attachment of these cells to the endothelium (coronary collaterals). (wikipedia.org)
  • ischemic
  • Numerous clinical studies have identified the functional significance of the collateral circulation in ischemic coronary syndromes ( ). (onlinejacc.org)
  • inflation
  • Inflation duration during autoperfusion angioplasty (513 +/- 303 seconds) was longer than for the pre- (107 +/- 55 seconds, p = 0.0004) and post- (139 +/- 71 seconds, p = 0.0006) standard dilatations. (ahajournals.org)
  • clinical
  • The FACT was a prospective multicenter, double-blind, randomized trial designed to evaluate whether treatment with nadroparin, a low-molecular-weight heparin, started 3 days before coronary angioplasty and continued for 3 months, affects angiographic restenosis or clinical outcomes. (acc.org)
  • Pretreatment with the low-molecular-weight heparin nadroparin continued for 3 months after balloon angioplasty will have a beneficial effect on angiographic restenosis or on adverse clinical outcomes. (acc.org)
  • chest pain
  • Maximal chest pain score during autoperfusion (3.2 +/- 3.5) was lower than for the pre- (6.1 +/- 2.1, p = 0.003) but not the post- (5.2 +/- 3.1, p = 0.07) standard angioplasty. (ahajournals.org)
  • However, some 25% of those with significant coronary artery narrowing experience no chest pain at all despite documented ischemia, or may only develop episodic shortness of breath instead of chest pain . (rxlist.com)
