Coronary artery bypass graft

OBJECTIVES: Use of radial artery as a second arterial graft, compared to a saphenous vein, in coronary artery bypass grafting (CABG) can improve late outcomes. However, the radial artery remains underutilized. We initiated a quality improvement (QI) initiative to increase usage of radial artery grafts. METHODS: During our four-month lead period, we disseminated evidence for radial artery graft usage to surgeons, developed a radial artery decision-making algorithm, and adopted endoscopic harvesting...

IMPORTANCE: Postoperative delirium is a common and impactful neuropsychiatric complication in patients undergoing coronary artery bypass grafting surgery. Cognitive training may enhance cognitive reserve, thereby reducing postoperative delirium. OBJECTIVE: To determine whether preoperative cognitive training reduces the incidence of delirium in patients undergoing coronary artery bypass grafting. DESIGN, SETTING, AND PARTICIPANTS: This prospective, single-blind, randomized clinical trial was conducted at 3 university teaching hospitals in southeastern China with enrollment between April 2022 and May 2023...

BACKGROUND: Carotid artery disease is prevalent among patients with coronary heart disease. The concomitant severe lesions in the carotid and coronary arteries may necessitate either simultaneous or staged revascularization involving coronary bypass and carotid endarterectomy. However, there is presently a lack of consensus on the optimal choice of surgical treatment tactics for patients with significant stenoses in both carotid and coronary arteries. The aim of the current study was to compare the 30-day and long-term outcomes of coronary and carotid artery revascularization surgery based on the simultaneous or staged surgical tactics...

INTRODUCTION: Coronary artery bypass grafting (CABG) is an essential surgical management modality for patients with coronary artery disease. Health-related quality of life (HRQoL) has become important because of the significant decrease in the mortality rate associated with CABG. We aimed to explore the factors that affect the quality of life after CABG. METHODS: This study used a descriptive correlational design to assess the determinants of HRQoL using the 36-item Short Form Health Survey questionnaire (SF-36)...

Postoperative atrial fibrillation (POAF) is commonly seen in patients undergoing coronary artery bypass grafting (CABG), increasing the risk of morbidity, mortality and hospital expenses. This study is aimed to evaluate the effect of partial cardiac denervation, which is achieved by cutting off the ligament of Marshall and resecting the fat pad along the Waterston groove, on the prevention of POAF after CABG. Patients planned for CABG at our center will be screened for eligibility for this study. A total of 430 patients will be randomized into intervention (partial cardiac denervation) group and control group...

BACKGROUND: IgG4-related disease (IgG4-RD) is a recently recognized fibro-inflammatory disorder that can affect almost any organ. IgG4-RD has also been reported in coronary arteries as periarteritis. IgG4-related coronary periarteritis may cause coronary artery aneurysms, and IgG4-related coronary artery aneurysms (IGCAs) are life-threatening. We describe a case of a patient with IGCA that highlights the usefulness and limitations of various IGCA evaluation modalities and provides insight into disease pathophysiology...

Embolization of entrapped intracardiac air represents a significant risk to the patient undergoing open-heart surgery. Entrapment of as little as 0.5 mL of gas in the heart can cause temporary myocardial dysfunction, cardiac arrhythmias, and systemic emboli. In contrast, larger emboli can disrupt the evaluation of heart function by limiting visualization during echocardiography. We present the case of a 67-year-old male who presented with dizziness, nausea, and chest pain. A left heart catheterization revealed multi-vessel disease...

UNLABELLED: A man in his 70s with a history of mitral valve replacement (MVR) and long-standing persistent atrial fibrillation (AF) presented with effort angina. Coronary angiography revealed severe stenosis of the left main coronary artery (LMCA). As it was an emergent case, PCI (percutaneous coronary intervention) was selected for treatment. Intravascular ultrasonography revealed no atherosclerotic lesions in the LMCA. The LMCA was effectively dilated by the drug-eluting stent. No elevation in intracardiac pressure was observed in cardiac catheterization after PCI...

UNLABELLED: An 89-year-old man with symptomatic severe aortic stenosis underwent transcatheter aortic valve implantation due to old age and a history of coronary artery bypass grafting. Computed tomography showed a tricuspid aortic valve and severe calcification at the aortic valve annulus, with a perimeter of 88.7 mm. The 34-mm Evolut PRO+ (Medtronic Inc., Minneapolis, MN, USA) was selected. After balloon aortic valvuloplasty, deployment of the Evolut PRO+ was attempted, but significant expansion failure was observed...

BACKGROUND: Right ventricular (RV) pacing is established as the most common ventricular pacing (VP) strategy for patients with symptomatic bradyarrhythmia. Some patients with high VP burden suffer deterioration of left ventricular (LV) function, termed pacing-induced cardiomyopathy (PICM). Patients who pace > 20% of the time from the RV apex are at increased risk of PICM, but independent predictors of increased RV pacing burden have not been elucidated in those who have a permanent pacemaker (PPM) inserted for bradyarrhythmia...

BACKGROUND: Patients with prior coronary artery bypass grafting (CABG) presenting with an acute coronary syndrome (ACS) have poor outcomes and the optimal treatment strategy for this population is unknown. METHODS: Using linked administrative databases, we examined patients with an ACS between 2008 and 2019, identifying patients with prior CABG. Patients were categorized by ACS presentation type and treatment strategy. Our primary outcome was the composite of death and recurrent myocardial infarction at one year...

Despite a 30% decline in the rate over the last decade, coronary artery bypass graft (CABG) surgery remains a common major surgical procedure with significant morbidity and mortality. Chronic liver disease (CLD) patients, with increased survival rates due to medical advancements, are now frequently being considered for CABG, bearing higher perioperative risks. This study investigates the association between CLD and in-hospital outcomes in CABG patients using retrospective data from the National Inpatient Sample (NIS) database (2016-2020) including 7,945 CLD patients undergoing CABG that were propensity score matched with an equivalent number of patients with no CLD undergoing CABG...

OBJECTIVE: Transit-time flow measurement (TTFM) represents a valid tool in the assessment of the quality of the anastomosis during coronary artery bypass graft (CABG). Nevertheless, a high variability limits its standardized use, lacking univocally accepted cut-off flow values. Our study analyzes TTFM data collected from a study population that underwent off-pump CABG (OP-CABG), with the aim to differentiate into subgroups according to the presence of diabetes mellitus. PATIENTS AND METHODS: Patients referred to the Cardiovascular Unit of S...

We describe our first experience with the Triolifter (Fuji Systems, Yokohama, Japan) in cardiac surgery. The Triolifter is a less expensive, novel organ fixation device developed as a fixation indenter mainly for traction of the lung under video-assisted surgery and is now available in Japan. An 84-year-old man diagnosed with unstable angina pectoris underwent emergency coronary artery bypass grafting (CABG) under cardiac arrest. Following the declamping of the aorta and the resumption of the beating heart, bleeding from the left anterior descending artery (LAD) anastomosis site was observed...

Myocardial bridging is an under-recognized cause of angina. This congenital anomaly occurs when a segment of the epicardial coronary artery has a short intra-myocardial course. A significant intra-myocardial course may lead to ischemia, causing anginal symptoms. In this case report, we discuss a rare presentation of myocardial bridging with symptoms of heart failure. The pathology led to a marked degree of ventricular dysfunction and a significant drop in cardiac output (CO), and the patient had severe exertional dyspnea and functional limitations...

OBJECTIVES: This retrospective study was conducted to evaluate the impact of saphenous vein(SV) harvesting with versus without perivascular tissue on the 5-year angiographic patency in coronary artery bypass grafting(CABG). METHODS: Among the 944 patients who received CABG between 2010 and 2015, 579 patients who received off-pump CABG using one SV as a Y-composite graft based on the in-situ left internal thoracic artery were enrolled. SV harvesting was performed using no-touch technique without perivascular tissue(the NoPVT group) in 342 patients and with perivascular tissue(the PVT group) in 237 patients...

OBJECTIVE: To establish the criteria for reversibility of myocardial contractility in patients with coronary artery disease (CAD) after coronary artery bypass grafting considering data of cardiac magnetic resonance imaging (MRI) and echocardiography. MATERIAL AND METHODS: We studied the results of coronary artery bypass grafting in 186 patients with CAD complicated by reduced left ventricular ejection fraction (<30%). All patients underwent cardiac MRI and echocardiography before surgery...

BACKGROUND: The prone position is recommended as supportive therapy in patients with moderate-to-severe acute respiratory distress syndrome (ARDS). However, little is known about prone position ventilation in patients with cardiogenic shock supported by extracorporeal membrane oxygenation (ECMO) plus Impella (ECPELLA) developing ARDS. CASE SUMMARY: A 66-year-old man with severe left ventricular dysfunction was admitted to a non-academic ECMO centre for a high-risk coronary artery bypass grafting...

BACKGROUND: Patients requiring coronary artery bypass grafting (CABG) are often loaded with antithrombotic drugs (AT) and are at an increased risk for perioperative bleeding complications. Active AT removal by a hemoadsorption cartridge integrated in the cardiopulmonary bypass circuit is increasingly used in this setting to reduce bleeding, and herein we describe the extension of this application in patients on AT undergoing off-pump coronary artery bypass (OPCAB). METHODS: Ten patients (80% male; mean age: 67...
