Introduction: Ultrafast tracking of anesthesia (UFTA) is practiced routinely, whereas immediate on-table extubation after off-pump coronary artery bypass (OPCAB) grafting surgery has many concerns. The purpose of our study was to evaluate the safety and feasibility of immediate extubation (IE) versus UFTA. Methods: Sixty patients were enrolled who underwent OPCAB surgery. The two groups IE and UFTA had thirty patients each. Inclusion criteria were patients for OPCAB surgery including left main stenosis...

Left main coronary artery (LMCA) disease is associated with increased morbidity and mortality. Coronary artery bypass grafting surgery (CABG) has always been the standard revascularization strategy for this group of patients. However, with the recent developments in stents design and medical therapy over the past decade, several trials have been designed to evaluate the safety and efficacy of percutaneous coronary intervention (PCI) as an alternative to CABG surgery in patients with LMCA disease. Recently, the results of two major trials, EXCEL and NOBLE, comparing CABG versus PCI in this patient population have been released...

Before the percutaneous spread, the mortality rate of patients with coronary heart disease not suitable for cardiac surgery was markedly high. This limit has been progressively exceeded with the advent of minimally invasive approaches, which, although was initially intended exclusively for low risk patients, was then employed in complex patients often too compromised to undergo cardiac surgery. Given to the rising of high-risk population, due to an increase of patients with multiple chronic conditions linked to the best care offered, we are witnessing an expansion of the high-risk percutaneous coronary interventions (PCI) population...

Background: The diagnosis of coronary artery disease (CAD) in patients with LBBB represents a clinical challenge. The presence of fragmented QRS (fQRS) complex on surface ECG may be related to myocardial ischemia, scarring or fibrosis. Objectives: To investigate the relation between fQRS and the presence and severity of CAD in patients with LBBB. Patients and methods: 56 patients with symptoms suggesting CAD and complete LBBB were submitted to full history taking and clinical examination, complete 12-leads electrocardiography (ECG) to confirm the diagnosis of LBBB and to diagnose the fragmented wide QRS (f-wQRS) complex, echocardiography, and coronary angiography; lesions with ⩾70% narrowing in major epicardial artery or ⩾50% narrowing in the left main coronary artery were considered significant; and Gensini score was calculated...

The advent of coronary angiography in the 1960s allowed for the risk stratification of patients with stable angina. Patients with unprotected left main coronary artery disease have an increased risk of death related to the large amount of myocardium supplied by this vessel. Although coronary angiography remains the preferred imaging modality for the evaluation of left main coronary artery stenosis, this technique has important limitations. Angiograms of the left main coronary artery segment can be difficult to interpret, and almost one-third of patients can be misclassified when fractional flow reserve is used as the reference...

In multivessel coronary artery disease (MVCAD), myocardial revascularisation can be achieved by percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG), with complete revascularisation on all diseased coronary segments or with incomplete revascularisation on selectively targeted lesions. Complete revascularisation confers a long-term prognostic benefit, but is associated with a higher rate of periprocedural events compared with incomplete revascularisation. In most patients with MVCAD, the main advantage of CABG over PCI is conferred by the achievement of more extensive revascularisation...

<u>Rationale:</u> A rapid and massive influx of inflammatory cells occurs into ischemic area following myocardial infarction, resulting in local release of cytokines and growth factors. Yet, the mechanisms regulating their production are not fully explored. The release of extracellular vesicles (EV) in the interstitial space curbs important biological functions, including inflammation, and influences the development of cardiovascular diseases. So far, there is no evidence for in situ release of cardiac EVs following myocardial infarction...

Background The aim of this study was to evaluate the rheolytic effects of stenting a mid-shaft/distal left main coronary artery (LMCA) lesion with and without ostial coverage. Stenting of the LMCA has emerged as a valid alternative in place of traditional coronary bypass graft surgery. However, in case of mid-shaft/distal lesion, there is no consensus regarding the extension of the strut coverage up to the ostium or to stent only the culprit lesion. Methods We reconstructed a left main-left descending coronary artery (LM-LCA)-left circumflex (LCX) bifurcation after analysing 100 consecutive patients (mean age 71...

The optimal management of unprotected left main coronary artery (ULMCA) disease is currently a debated topic. Percutaneous coronary intervention (PCI) has seen an increased adoption for the management of ULMCA disease after numerous small-scale randomised trials and cohort studies showed equipoise with coronary artery bypass grafting (CABG) for low complexity lesions. The recently published NOBLE and EXCEL trials are two of the largest international randomised clinical trials comparing PCI and CABG in patients with ULMCA disease...

Due to its potential prognostic implications and technical complexity, revascularisation of left main coronary artery (LMCA) disease requires careful consideration. Since publication of the results of the SYNTAX study, and more recently the EXCEL and NOBLE trials, there has been particular interest in percutaneous revascularisation of the LMCA. It is becoming clear that percutaneous revascularisation of LMCA disease requires appropriate lesion preparation and carefully optimised stenting in order to offer patients a treatment option as effective as coronary artery bypass grafting...

Objective -to identify the role of occupational hazards (OH) as a risk factor of onset and unfavorable outcome of coronary artery disease (CAD). Retrospective study included analysis of 307 case reports of CAD patients, including 59 patients with long term history of OH exposure. Prospective study included observation of 244 STEMI patients during their in-patient treatment, including 113 patients with prior exposure to OH. OH were demonstrated to contribute to the risk of CAD, and to be directly involved in atherosclerotic coronary artery (CA) injury, its role being equal to that of the classical risk factors, such as arterial hypertension (AH), dyslipidemia, and diabetes mellitus (DM)...

BACKGROUND: Aortic knob width (AKW), which can be measured easily in simple radiography, is associated with the degree of dilatation and tortuosity of the aortic arch. Pulsatile stress influences aortic geometry. This study was carried out to investigate whether AKW can represent invasively measured aortic pulse pressure (APP). METHODS: A total of 252 patients who underwent invasive coronary angiography (ICA) for the evaluation of coronary artery disease were enrolled...

OBJECTIVES: The aim of this study was to develop and validate a risk adjustment model for 30-day mortality after transcatheter aortic valve replacement (TAVR) that accounted for both standard clinical factors and pre-procedural health status and frailty. BACKGROUND: Assessment of risk for TAVR is important both for patient selection and provider comparisons. Prior efforts for risk adjustment have focused on in-hospital mortality, which is easily obtainable but can be biased because of early discharge of ill patients...

OBJECTIVES: Considering the good immediate results reported for transcatheter aortic valve implantation in high-risk patients, the role of conventional aortic valve replacement (AVR) is being questioned, especially in elderly patients. The aim of this study was to evaluate our long-term results of conventional AVR in octogenarians. METHODS: A total of 2005 patients aged ≥80 years underwent AVR for aortic stenosis in our institution between 1978 and 2011. Of these, 1009 (50%) patients had an associated extracardiac comorbidity and 650 (32%) patients had coronary lesions...

We report a case of Tangier disease with Leriche syndrome and bleeding tendency. In this male patient, nasal hemorrhage had been observed frequently throughout childhood. At 46 years old, he experienced effort angina, and coronary angiography demonstrated 75% stenosis in the right coronary artery. Orange-colored tonsils, mild hepatosplenomegaly and very low levels of serum high-density lipoprotein cholesterol (HDL-C) were observed, and the patient was diagnosed with Tangier disease. At 52 years old, effort angina recurred...

Percutaneous coronary intervention (PCI) has emerged as an alternative treatment to coronary artery bypass grafting (CABG) in patients with unprotected left main coronary artery disease (ULMCAD). However, the optimal treatment for ULMCAD concomitant with chronic kidney disease (CKD) was rarely addressed. Herein, we compare the long-term outcomes of these patients treated with CABG or PCI.From January 2004 to December 2010, 185 patients with ULMCAD and CKD undergoing PCI (n = 84) or CABG (n = 101) were matched for the selection criteria...

Importance: Ischemia-guided revascularization is the cornerstone of contemporary management of coronary artery disease and has evolved from noninvasive functional evaluation to real-time assessment with invasive physiological indices during diagnostic catheterization. However, serial/diffuse disease is common, and revascularization decisions often need to be made about individual lesions within the same vessel. It is unclear whether current physiological techniques, such as fractional flow reserve, can be reliably used to discern the individual contribution of lesions within a serially diseased vessel with erroneous measurements, potentially leading to suboptimal revascularization decisions...
