incomplete revascularization

Masahiro Koide, Keiji Inoue, Akiko Matsuo, Hiroshi Fujita
BACKGROUND: Heavy coronary artery calcification is responsible for stent underexpansion, which is associated with increased in-stent restenosis. Here we report a case in which optical coherence tomography (OCT) demonstrated that the metal component of an underexpanded stent previously implanted in a heavy calcified lesion had been completely removed after ablation with rotational atherectomy. CASE PRESENTATION: An 83-year-old man with exertional angina was referred to our hospital...

OBJECTIVE: In this study, we compared the impact of two main strategies of intervention against multivessel coronary disease (MVD), complete revascularization (CR) and incomplete revascularization (IR), on patients' quality of life. PATIENTS AND METHODS: 210 patients with multivessel disease were selected for this study. The diagnosis was confirmed by coronary angiography, and patients were divided in two different groups according to the type of revascularization method they received: (1) the complete revascularization (CR) group and (2) the incomplete revascularization (IR) group...

Heart rate is an established prognostic marker for longevity and is an important contributor in the pathophysiology of various cardiovascular diseases, including ischemic heart disease and heart failure. Most ischemic episodes are triggered by an increase in heart rate, which causes an imbalance between myocardial oxygen delivery and consumption. In addition, increased heart rate is a modifiable risk factor for chronic heart failure. Ivabradine, an inhibitor of If ion channels, is an approved second-line anti-ischemic drug for the treatment of angina...

Provisional use of rotational atherectomy (RA) is indicated for procedural success in heavily calcified lesions. In the current study, RA use at three high volume percutaneous coronary intervention (PCI) centers between 2005 and 2013 was 1.4%. MACE rate was 17.8% at median follow-up of 22 months. Peripheral vascular disease (PVD), diabetes mellitus (DM), acute coronary syndrome (ACS), and SYNTAX > 23 were found to be independently associated with MACE. With increasing complexity of disease and SYNTAX score, there is usually an increase in severity of calcification and need for atherectomy...

The value of late gadolinium-enhanced (LGE) magnetic resonance imaging (MRI) for the prediction of functional recovery after surgical revascularization has been previously established. However, the impact of LGE-MRI on the long-term prognosis after coronary artery bypass grafting (CABG) remains incompletely understood. Therefore, we aimed to evaluate the long-term prognostic value of LGE-MRI, based on the presence or absence of left ventricular (LV) dysfunction, in patients with coronary artery disease undergoing CABG...

BACKGROUND: Successful trachea transplantation comprises the use of biocompatible constructs with little immune-reactivity, submucosal revascularization and creation of an epithelial covering. Allogenic chondrocytes might be protected from an overt immune-response due to physical isolation. Our aim was to evaluate in-vivo biocompatibility of allotracheae, stripped of their highly-immunogenic inner lining. Secondly, we established whether these constructs might serve as suitable scaffolds for autologous epithelial grafting...

The optimal degree of revascularization for patients with chronic multivessel coronary artery disease remains an unsolved issue. Intuitively, complete revascularization decreases cardiovascular events and improves outcomes compared to incomplete procedures, but in recent years the concept of incomplete revascularization moved from a sub-optimal or a defective treatment towards the most appropriate revascularization technique in some categories of patients. A reasonable level of incomplete anatomic revascularization has been shown to be safe and achievable with both percutaneous (PCI) and surgical procedures (CABG), despite with different long-term outcomes...

Recent improvements in medical and surgical coronary revascularization techniques have significantly improved outcomes for patients with acute myocardial infarction (MI). However, large infarctions are often followed by a poorly understood process of pathological ventricular remodelling, which fails to return the heart to its premorbid state. Although it remains incompletely understood, there is increasing interest in the role of the immune system in this process. One hypothesis is that released cardiac proteins become the focus of an immune response that results in the formation of functionally significant autoantibodies...

BACKGROUND: The clinical impact of completeness of revascularization on adverse cardiovascular events remains unclear among patients with multivessel coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI). METHODS: This analysis included consecutive patients with multivessel CAD, who underwent PCI with drug-eluting stents (DES) during the period from January 1, 2003, through to December 31, 2013. We compared the outcomes in patients, who achieved complete (CR) versus incomplete revascularization (IR) at the time of PCI...

Although randomized trial data suggest that complete revascularization improves outcomes after percutaneous coronary intervention (PCI), the impact of differing revascularization strategies in octogenarians is not well defined. We performed a retrospective analysis, which was conducted of 9,628 consecutive patients who underwent PCI at a large UK center. Octogenarians were more likely to have significant co-morbidity, a higher Mehran bleed risk score (24.5 ± 6.8 vs 13.3 ± 7.4, p <0.0001), and more complex disease (baseline SYNTAX score 18...

BACKGROUND: Stenting-induced edge dissections (ED) can be assessed in detail by optical coherence tomography (OCT). This study sought to investigate the incidence, morphological characteristics, and spontaneous healing course of OCT-identified EDs following drug-eluting stent (DES) implantation in a non-ST segment elevation myocardial infarction (NSTEMI) patient-population. METHODS: Acute vessel wall injury at the 5-mm stent adjacent distal and proximal reference segments was assessed by post-procedure OCT and intravascular ultrasound (IVUS) in n=97 NSTEMI-patients (n=97 lesions)...

BACKGROUND: Clinical trial data show overall favorable outcomes of paclitaxel-eluting stents for treatment of femoro-popliteal (FP) occlusive disease. However, external validity of trial results may be restricted to less complex FP lesions, and limited data on outcomes of paclitaxel-eluting stents in real world practice have been published. METHODS: This is a retrospective analysis of data of all patients who received Zilver® PTX® for FP lesion from February 2013 to October 2014 at our center...

Based on this meta-analysis of primarily observational data, complete revascularization (CR) is associated with a reduced risk of death, MI, and repeat revascularization in patients with multivessel coronary artery disease (MVCAD) as compared with incomplete revascularization (IR). Given the current state of evidence, the likelihood of achieving complete revascularization should influence whether PCI or CABG is the best strategy in patients with MVCAD. Given the lack of randomized trials in this area, more robust trial data will address the validity of these findings...

Cutaneous radiation syndrome caused by high dose located irradiation is characterized by delayed symptoms, incomplete wound healing, and poor revascularization. Subcutaneous adipose tissue derived stromal/stem cells have been shown to improve skin repair in a minipig model of cutaneous radiation syndrome despite a subcutaneous defect being a consequence of radio-induced muscular fibrosis. Based on the pro-myogenic potential of stromal/stem cells, a new protocol combining subcutaneous and intramuscular injections was evaluated in a preliminary study...

The study was aimed at analysing the outcomes of multivessel revascularization by means of percutaneous coronary intervention (PCI) in a total of 190 patients presenting with ST segment elevation myocardial infarction (STEMI) and multivessel lesion (MVL) of coronary arteries. Patients with unsuccessful PCI or those having received no planned second stage of revascularization for any reason were excluded from the study. The patients were subdivided into two groups: Group One comprised those having received appropriate complete revascularization (CR) within the framework of multivessel stenting (MVS) during primary PCI or a stagewise approach (n=137), Group Two included patients with the so-called appropriate incomplete revascularization (AIR) after MVS or stagewise PCI (n=53)...
