Drug-coated balloon angioplasty: predicting outcomes based on different patterns of drug-eluting stent restenosis
This study sought to assess outcomes of different patterns of DES-ISR treated with DCB. From December 2014 to December 2016, a total of 160 DES-ISR lesions treated with DCB were retrospectively evaluated. Restenosis patterns were classified into two groups according to Mehran classification: focal, defined as
Authors: Zotz RJ, Dietz U, Lindemann S, Genth-Zotz S Abstract Coronary restenosis is the answer of the arterial wall to a mechanical violation through balloon angioplasty, bare-metal (BM) stent implantation or rotational atherectomy through repeated narrowing. It has great clinical and prognostic relevance and occurs in approximately 30% of non-coated stents and in 10% of coated coronary stents. The wound healing process that precedes restenosis includes inflammatory reactions, cellular proliferation and remodeling of the arterial wall, where protein synthesis of the extracellular matrix is initiated. The infl...
CONCLUSIONS: The risk factors obtained from the medical history and during the hospitalisation improve the risk stratification during the post-discharge period after hospitalisation for ACS. PMID: 29350382 [PubMed - indexed for MEDLINE]
CONCLUSION: PCI is a safe and effective method of revascularization in the elderly patients, and some clinical and procedural factors can predict MACE in this group of patients. PMID: 30113855 [PubMed - in process]
Contrast agent dose and slow/no-reflow in percutaneous coronary interventions : A case-control study of patients with non-ST-segment elevation acute coronary syndromes. Herz. 2018 Apr 10;: Authors: Ding S, Shi Y, Sun X, Cao Q, Dai H, Guan J Abstract BACKGROUND: The angiographic slow/no-reflow phenomenon after primary percutaneous coronary intervention carries a poor prognosis for patients with non-ST-segment elevation acute coronary syndrome (NSTEACS). There is evidence that contrast agents cause endothelial dysfunction, myocardial cell damage, and coronary spasms. We hypothesized that the co...
Abstract ObjectivesTo evaluate the association of diabetes mellitus (DM) with clinical and angiographic characteristics and outcomes of patients with popliteal and infrapopliteal peripheral arterial disease (PAD) undergoing peripheral vascular intervention (PVI). BackgroundClinical features and outcomes in patients with DM and popliteal or infrapopliteal PAD undergoing PVI are not well described. MethodsUsing the data from the laser in popliteal and infrapopliteal stenosis study, we retrospectively examined the association of diabetes with clinical and angiographic characteristics and risk adjusted short‐ and intermediat...
A 78-year-old man with hypertension and diabetes mellitus had a 20-min episode of expressive aphasia. Computed tomography (CT) head and neck angiogram showed a near occlusion of the proximal left internal carotid artery (ICA) with distal collapse of the vessel. He was already on optimal medical management and agreed to undergo carotid artery stenting (CAS). Fifteen days after onset of symptoms balloon angioplasty and stenting of the left ICA was performed under distal embolic protection (Fig. 1 A, B).
Conclusion Rarely, prolonged bradycardia may occur and persist for greater than 1 week after carotid angioplasty and stenting even in cases without post stent angioplasty. Disclosures D. Archer: None. J. Ferdous: None. Y. Alderazi: None.
CONCLUSION: Below-knee stent angioplasty for critical limb ischemia results in good clinical outcome, but the major adverse event rate is high. Diabetes mellitus is associated with a high rate of mortality and amputation. Orv. Hetil., 2017, 158(11), 418-425. PMID: 28287292 [PubMed - in process]
CONCLUSIONS: Omani patients treated with PCI were much younger than Western patients with a high prevalence of risk factors. Successful PCI was achieved in a large percentage of patients with a low incidence of in-hospital complications and mortality. At one-year follow-up, the majority patients had a good clinical outcome. PMID: 28042404 [PubMed]
A 41year old male, a chronic smoker, presented with anterior ST-elevation myocardial infarction (STEMI) in August 2014. He had a known history of diabetes mellitus and positive family history of ischemic heart disease. Emergent coronary angiography showed a single vessel disease with acute thrombotic occlusion of mid left anterior descending (LAD) artery (Fig. 1A). Primary percutaneous coronary intervention (PPCI) was performed with aspiration thrombectomy and predilatation of mid LAD with a 2.0×15mm balloon.
