Coronary artery bypass and angioplasty

BACKGROUND: While lifestyle changes, management of coronary artery disease (CAD) risk factors, myocardial revascularization procedures, and medication can improve a patient's prognosis, de novo native coronary lesions and in-stent restenosis (ISR) remain significant clinical concerns. ISR is more frequent with a bare-metal stent than with a drug-eluting stent and has been documented in around 12% of DES patients. Acute coronary syndrome (ACS) manifests as unstable angina in about 30% to 60% of ISR patients...

Background: Hysterectomy, oophorectomy, and tubal ligation are common surgical procedures. The literature regarding cardiovascular disease (CVD) risk after these surgeries has focused on oophorectomy with limited research on hysterectomy or tubal ligation. Materials and Methods: Participants in the Nurses' Health Study II ( n  = 116,429) were followed from 1989 to 2017. Self-reported gynecologic surgery was categorized as follows: no surgery, hysterectomy alone, hysterectomy with unilateral oophorectomy, and hysterectomy with bilateral oophorectomy...

INTRODUCTION: Coronary artery disease (CAD) is considered an independent risk factor for COVID-19. However, no study has specifically examined the clinical manifestations and outcomes of COVID-19 in patients with ischemic heart disease (IHD). METHODS: In a retrospective case-control study between 20 March 2020 to 20 May 2020, the medical record of 1611 patients with laboratory-confirmed SARS-CoV-2 infection was reviewed. IHD was defined as a history of an abnormal coronary angiography, coronary angioplasty, coronary artery bypass graft (CABG), or chronic stable angina...

UNLABELLED: A 65-year-old patient with the left anterior descending artery (LAD) ostial stenosis proved by coronary angiography is presented. LAD ostial stenosis is an uncommon condition whose etiology is unknown. The patient also had a coronary artery bypass graft combined with aortic valve replacement 13 years ago. The clinical and angiographic profiles of the patient are discussed here, supported by the literature. CASE PRESENTATION: A 65-year-old female patient with a medical history of hypertension and dyslipidemia came to the outpatient department with a complaint of chest pain and shortness of breath...

Coronary artery disease is the predominant aetiology of heart failure and left ventricular dysfunction in industrialized countries. The pathophysiological substrate of hibernating myocardium constitutes the conceptual target of coronary revascularization by coronary artery bypass graft (CABG) or coronary angioplasty or percutaneous coronary intervention (PCI). Studies, mainly observational, conducted in the past have demonstrated a prognostic benefit of CABG on survival. These findings were confirmed by the long-term follow-up of the STICH study in which, however, documentation of inducible ischaemia or myocardial viability was not predictive of a prognostic benefit of CABG...

The aim of this review is to identify a preventive strategy in order to minimize the risk of adverse events in patients with coronary syndromes and acute exposure to high-altitude. For this purpose we searched the electronic database of PubMed, EMBASE, and Web of Science for studies published in the last 30 years in this field. The conclusions of this review are: patients with stable coronary artery disease on optimal treatment and in a good physical condition can tolerate traveling to high altitude up to 3500 m; on the other hand, patients with unstable angina or recent myocardial infarction no older than 6 months should take less interest in hiking or any activity involving high altitude...

OBJECTIVE: Numerous mechanisms have been proposed for the no-reflow phenomenon (NRP) in the literature including leukocyte intravascular plugging, microembolisms, and extrinsic coagulation pathway activation. Some of the more recent studies suggested a relationship between NRP and systemic immune-inflammation index (SII) in different contexts. To this end, the objective of this study was to investigate the relationship between NRP and SII in acute coronary syndrome (ACS) patients with coronary artery bypass grafting (CABG) who underwent percutaneous transluminal coronary angioplasty (PTCA) or percutaneous coronary intervention (PCI) of saphenous vein graft (SVG)...

A 55-year-old man presented with chest pain and was diagnosed with non-ST-segment elevation myocardial infarction. Coronary angiography revealed a 95% eccentric lesion in the mid-right coronary artery. After 3 intracoronary stents were placed, the guidewire became entrapped in 1 of the stents; multiple attempts at retrieval were unsuccessful. Ultimately, the guidewire fractured, and a coronary artery bypass graft surgery was performed to remove the guidewire fragments. This report reviews the procedural steps for wire retrieval that are critical for operators to avoid coronary artery bypass surgery...

INTRODUCTION: Behavioral and physiological risk factors worsen the prognosis of coronary heart disease (CHD). Anxiety is known to be a psychological predictor of CHD. In this study, we investigated whether this factor is associated with all-cause mortality in CHD patients in the long term. METHODS: We studied 180 patients (mean age 60.6 SD 9.2 years, 26% women) with CHD from the Berlin Anxiety Trial (BAT) and the Stepwise Psychotherapy Intervention for Reducing Risk in Coronary Artery Disease (SPIRR-CAD) study...

During the acute phase of myocardial infarction, the culprit artery must be revascularized quickly with angioplasty. Surgery then completes the procedure in a second stage. If emergency surgery is performed, the resulting death rate is high; 15-20% of patients are operated on within the first 48 h after the myocardial infarction. The timing of surgical revascularization and the patient's preoperative state influence the mortality rate. We aimed to evaluate the impact of surgery delay on morbimortality. Between 2007 and 2017, a retrospective monocentric study was conducted including 477 haemodynamically stable patients after myocardial infarction who underwent an urgent coronary bypass...

BACKGROUND: The optimal alternative treatment strategy to coronary artery bypass graft surgery (CABG) for in-stent restenosis (ISR) in left main (LM) coronary artery disease remains uncertain. METHODS: We retrospectively screened all intervention reports from an intervention database and extracted those mentioning an LM stent. We then manually confirmed reports involving LM ISR and divided them into two groups, those in which the patient received a new drug-eluting stent (new-DES) strategy, and those in which the patient received a drug-coated balloon (DCB) only...

BACKGROUND: Coronary artery embolism is a rare, life-threatening complication in patients with infectious endocarditis. Percutaneous transluminal coronary angioplasty is a common treatment; however, a coronary artery aneurysm may develop at the angioplasty site. CASE SUMMARY: A 33-year-old women had been hospitalized in another institution due to cardiopulmonary arrest caused by embolic occlusion in the left main artery and infective endocarditis on mitral valve...

BACKGROUND: There is ongoing debate regarding the optimal strategy and timing for the surgical management of patients with severe concomitant carotid and coronary artery disease. Anaortic off-pump coronary artery bypass (anOPCAB), which avoids aortic manipulation and cardiopulmonary bypass, has been shown to reduce the risk of perioperative stroke. We present the outcomes of a series of synchronous carotid endarterectomy (CEA) and anOPCAB. METHODS: A retrospective review was performed...

BACKGROUND: Whether complete revascularization (CR) or incomplete revascularization (IR) may affect long-term outcomes after PCI) and coronary artery bypass grafting (CABG) for left main coronary artery (LMCA) disease is unclear. OBJECTIVES: The authors sought to assess the impact of CR or IR on 10-year outcomes after PCI or CABG for LMCA disease. METHODS: In the PRECOMBAT (Premier of Randomized Comparison of Bypass Surgery versus Angioplasty Using Sirolimus-Eluting Stent in Patients with Left Main Coronary Artery Disease) 10-year extended study, the authors evaluated the effect of PCI and CABG on long-term outcomes according to completeness of revascularization...

Coronary subclavian steal syndrome (CSSS) caused by left subclavian artery (LSA) stenosis is a rare cause of myocardial infarction in patients having coronary artery bypass grafting (CABG), and it has also been observed after an arteriovenous fistula (AVF) was made. A 79-year-old woman who had undergone CABG years earlier and an AVF creation 1 month before experienced a non-ST-elevation myocardial infarction (NSTEMI). While selective catheterization of the left internal thoracic artery graft was impossible, a computed tomography scanner showed patency of all bypasses and proximal subocclusive LSA stenosis, and the digital blood pressure measurements objectified a haemodialysis-induced distal ischaemia...

Background Certain symptoms associated with infertility are associated with cardiovascular disease, including menstrual cycle irregularity, early menopause, and obesity; however, few studies have investigated the association between infertility and cardiovascular disease risk. Methods and Results Participants in the NHSII (Nurses' Health Study II) who reported infertility (12 months of trying to conceive without success, including women who subsequently conceived) or who were gravid, with no infertility were followed from 1989 until 2017 for development of incident, physician-diagnosed coronary heart disease (CHD) (myocardial infarction, coronary artery bypass grafting, angioplasty, stent) and stroke...

BACKGROUND: Patients undergoing coronary artery bypass graft (CABG) sometimes have critical proximal lesion in left anterior descending (LAD) artery or chronic total occlusion followed by either skip lesions or diffuse disease of late mid-to-distal LAD artery. Such lesions require endarterectomy or atheroma bridging via long venous or arterial patch (patch-plasty), for which clinical outcomes are conflicting in studies due to a more thrombogenic milieu created by patch-plasty as well as incomplete endarterectomy...

BACKGROUND: Percutaneous coronary intervention (PCI) is the standard-of-care treatment for left main stenosis as an alternative to bypass surgery. In addition, severe coronary lesion calcification can be modified by intravascular lithotripsy (IVL). However, with PCI and debulking treatment options, there are inherent limitations. PCI poses an increased health burden for the treating physician that is associated with wearing a heavy, lead-lined apron and being exposed to radiation. To overcome these issues, a robotically assisted angioplasty system (rPCI) was established that enables the operator to perform PCI remotely in routine clinical procedures...

BACKGROUND & AIMS: To determine variations in coronary artery disease (CAD) clinical presentation, interventions, and outcomes in patients with diabetes vs without, a prospective study was performed. METHODS: Successive patients with predominantly acute coronary syndromes who underwent percutaneous coronary intervention (PCI) were enrolled from January 2018 to March 2021. Patients with diabetes were compared to those without diabetes to determine differences in clinical and angiographic features and outcomes...
