Although post-PTCA flow velocity correlated with angiographic cineframes-to-opacification count ( r. The incidence of multivessel coronary artery disease (MVD) was lower in the E-ROSC group than in the L-ROSC group (16.7% versus 58.8%, P = 0.001).Collateral and TIMI flow were not associated with ease of resuscitation, but MVD may have a negative impact on resuscitation, especially in VF patients.Ĭollapse to resuscitation time Coronary angiography Resuscitation. TIMI grade 3 flow increased to 21.810.9 cm/s ( P <.05 versus before PTCA). Conclusion: Administration of IC medication via distal route is observed to be more effective for the treatment of slow flow/no-reflow during primary PCI. 76 p 0.027 as compared to proximal cohort. We included ACS patients who had CPA with ventricular fibrillation (VF) as an initial rhythm, were successfully resuscitated, underwent coronary angiography (CAG), had a culprit lesion, and were diagnosed with ACS (n = 58 age, 63.7 ± 12.0 years 93.1% male).We divided the 58 patients into two groups, an early ROSC group (ROSC ≤ 20 minutes: E-ROSC) and a late ROSC group (ROSC > 20 minutes: L-ROSC), and then analyzed their characteristics.The finding of a collateral artery for the culprit lesion location, Rentrop II-III, and TIMI III flow on CAG on arrival presented no significant differences between the two groups (Rentrop II-III: 25.0% versus 23.5%, P = 0.90 TIMI III: 33.3% versus 35.3%, P = 0.88). Final TIMI III flow was achieved in significantly higher number of patients in distal cohort with the frequency of 88 vs. Hence, we investigated this relationship in ACS patients with OHCA.A cohort of 2779 patients was admitted to our emergency center due to cardiopulmonary arrest (CPA) between April 2011 and March 2015. The relationship between the findings from the study of coronary images and return of spontaneous circulation (ROSC) interval is still unknown. The lack of improvement in flow reserve after both balloon angioplasty and rotational atherectomy suggests that the mechanisms of improved flow reserve may be device independent, and remain unexplained.Acute coronary syndrome (ACS) is the major cause of out-of-hospital cardiac arrest (OHCA). Similarly, no change in coronary flow reserve has been reported immediately after balloon angioplasty alone. Despite the significant improvement of coronary hemodynamics noted immediately after combined rotational atherectomy and balloon angioplasty, coronary flow reserve remained abnormal. Regardless of the mechanism, the transient reduction of coronary flow was rapidly reversed by coronary vasodilators. Immediately after rotational atherectomy alone, there is a reduction in angiographically determined coronary flow, suggesting either distal microvascular spasm or distal microvascular obstruction. However, no change in coronary flow reserve was noted (1.24 +/- 0.1 vs. REGISTRATION: URL: Unique identifier: NCT04699110. The advantage of this approach is that it will enhance reperfusion before PCI, with very low rates of intracranial hemorrhage (<0.1). 2.6 +/- 0.1 mm P < 0.05), coronary flow (81 +/- 14 to 154 +/- 18 ml/min P < 0.05), maximal absolute velocity (23 +/- 4 to 52 +/- 4 cm/sec P < 0.05), and vascular resistance decreased (1.74 +/- 0.4 to 0.74 +/- 0.4 mm Hg/ml/min P < 0.05). A significantly higher frequency of post-treatment TIMI III flow grade and lower final corrected TIMI frame count with relatively better achievement of myocardial blush grade III translate into it displaying relatively better efficacy than adenosine. In 4 trials, including TIMI 14, 21 an improvement to 30 to 35 TIMI grade 3 flow (and 50 patency) has been achieved with the administration of IIb/IIIa inhibitors in the Emergency Department before PCI. Following adjunctive balloon angioplasty, there was an increase in lumen diameter (1.29 +/- 0.1 vs. Intracoronary nitroglycerin and verapamil was associated with return to baseline of both measurements. In addition, the number of Cineframes to Opacification of a preselected distal landmark increased twofold (from 49 +/- 12 to 118 +/- 27 frames P < 0.05). After rotational atherectomy alone, two patients had TIMI-I, four patients had TIMI-II, and four patients had TIMI-III flow. All patients had TIMI-III flow at baseline. The aim of this study was to determine the coronary hemodynamic changes by Doppler flow wire before and after rotational atherectomy and adjunctive balloon angioplasty in 10 patients. The phenomenon of "no-reflow" has been described frequently after rotational atherectomy. ![]()
