Pathology of the Thin‐Cap Fibroatheroma: Tập 16 Số 3 - Trang 267-272 - 2003
Renu Virmani, Allen Burke, Frank D. Kolodgie, Andrew Farb
Thin cap atheroma is the precursor of plaque rupture, which accounts for a
majority of coronary thrombi. The morphologic features of thin cap atheromas
that predict rupture are unknown, but we know from studies of ruptured plaques
that large necrotic cores, fibrous cap <65 microns and numerous macrophages
within the cap likely indicate instability. There is some evidence that a
speckled pattern of... hiện toàn bộ
Microvessels in Chronic Total Occlusions: Pathways for Successful Guidewire Crossing? Tập 18 Số 6 - Trang 425-436 - 2005
Bradley H. Strauss, Amit Segev, Graham A. Wright, Beiping Qiang, Nigel R. Munce, Kevan Anderson, General Leung, Alexander Dick, Renu Virmani, Jagdish Butany
Arterial chronic total occlusions (CTO) are a common and clinically relevant
problem in patients with coronary artery disease. Percutaneous coronary
intervention (PCI) success rates in a wide range of CTO are low, primarily due
to inability of guidewire crossing. The pathophysiology of CTO is poorly
understood and limits our ability to introduce innovative therapies. Recent
studies from our labora... hiện toàn bộ
Use of Stent Grafts and Coils in Vessel Rupture and Perforation Tập 21 Số 1 - Trang 86-99 - 2008
Khung Keong Yeo, Jason H. Rogers, John R. Laird
Vessel rupture and perforation are important complications of percutaneous
treatment of coronary and peripheral arterial disease. These complications can
result in abrupt vessel closure, distal organ injury, bleeding into the
surrounding tissue, and death. Prompt management of such complications is
therefore critically important. This paper reviews the management of vessel
rupture and perforation,... hiện toàn bộ
Transluminal Angioplasty, Thrombolysis, and Stenting for Extracranial and Intracranial Cerebral Vascular Disease Tập 9 Số 3 - Trang 245-255 - 1996
Randall T. Higashida, Fong Y. Tsai, Van V. Halbach, Christopher F. Dowd, Grant B. Hieshima
Percutaneous transluminal angioplasty, alone or in conjunction with thrombolysis
and/or stenting, is now being performed in selected cases for hemodynamically
significant stenosis (> 70%), involving both extracranial and intracranial
cerebral vascular lesions. In the majority of cases, atherosclerosis was the
major cause for symptomatic narrowing, although other causes included
fibromuscular dyspl... hiện toàn bộ
Catheter Closure of Congenital/Acquired Muscular VSDs and Perimembranous VSDs Using the Amplatzer Devices Tập 16 Số 5 - Trang 399-407 - 2003
Basil D. Thanopoulos, Karanassios Evangelos, George S. Tsaousis, G S Papadopoulos, Christodoulos Stefanadis
Over the past 10 years a variety of occluding devices has been used for
transcatheter closure of ventricular septal defects (VSDs), but none has gained
wide acceptance. This article presents the experience of transcatheter closure
of muscular and perimembranous VSDs in 22 and 13 patients, respectively, with
the new Amplatzer VSD occluders. Overall total occlusion was achieved in 95% and
92.3% of p... hiện toàn bộ
Long-Term Outcomes of Extent of Revascularization in Complex High Risk and Indicated Patients Undergoing Impella-Protected Percutaneous Coronary Intervention: Report from the Roma-Verona Registry Tập 2019 - Trang 1-10 - 2019

Objective. To investigate the effect of extent of revascularization in complex
high-risk indicated patients (CHIP) undergoing Impella-protected percutaneous
coronary intervention (PCI). Background. Complete revascularization has been
shown to be associated with improved outcomes. However, the impact of more
complete revascularization during Impella-protected PCI in CHIP has not been
reported. Meth... hiện toàn bộ
No Cardioprotective Benefit of Ischemic Postconditioning in Patients With ST‐Segment Elevation Myocardial Infarction Tập 26 Số 5 - Trang 482-490 - 2013

AbstractBackgroundPostconditioning is a potential cardioprotective strategy that
has demonstrated conflicting and variable reductions in infarct size in human
trials.ObjectivesTo determine whether postconditioning could increase the extent
of myocardial salvage in patients with acute ST‐segment elevation myocardial
infarction undergoing primary percutaneous coronary intervention
(PPCI).MethodsOne ... hiện toàn bộ
Direct Stenting Versus Pre‐Dilation in ST‐Elevation Myocardial Infarction: A Systematic Review and Meta‐Analysis Tập 28 Số 2 - Trang 119-131 - 2015

ObjectivesThis study aimed at comparing direct stenting (DS) versus stenting
with pre‐dilation (SP) in patients with ST‐elevation myocardial infarction
(STEMI), using a systematic review and meta‐analysis of published
evidence.BackgroundThere is conflicting evidence whether stenting strategy
impacts clinical outcomes in patients with STEMI.MethodsWe searched EMBASE,

infarction (AMI) complicated by refractory cardiogenic shock (CS) who underwent
mechanical circulatory support with Impella 2.5.BackgroundAMI complicated by CS
remains a highly fatal condition. A potent and minimally invasive left

Is Postdilatation with a Noncompliant Balloon Necessary after Coronary Stent Deployment during Primary Angioplasty? Tập 26 Số 4 - Trang 325-331 - 2013

AbstractBackgroundPostdilatation (PD) with noncompliant balloon during elective
percutaneous coronary intervention (PCI) is performed usually in clinical
practice in order to optimize stent expansion. However, current knowledge about
its use in patients undergoing primary PCI is controversial. This study aims to
evaluate the angiographical and clinical results of PD in patients who underwent
