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 t...... hiện toàn bộ
Microvessels in Chronic Total Occlusions: Pathways for Successful Guidewire Crossing? Tập 18 Số 6 - Trang 425-436 - 2005

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 s...... 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 ru...... 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 fibromus...... 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 du...... 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...... hiện toàn bộ

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 evalu...... hiện toàn bộ
