  • lesion
  • Our initial experience indicated that duration of angina and coronary lesion severity showed a weak, although statistically significant, correlation with recruitability of collateral vessels assessed during acute balloon coronary occlusion ( ). (onlinejacc.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)
  • 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
  • These findings are important for risk stratification of patients undergoing interventions for ischemic coronary syndromes. (onlinejacc.org)
  • 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)
  • intervention
  • The sirolimus is formulated in a polymer coating that affords controlled release through the healing period following coronary intervention. (wikipedia.org)
  • Chest
  • 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)
