Coronary artery bypass and angioplasty

BACKGROUND: No study has investigated the perioperative management and clinical outcomes in patients who are receiving rivaroxaban 2.5 mg bid and ASA 81-100 mg daily. METHODS: Sub-analysis of the COMPASS trial to assess perioperative management and clinical outcomes in patients with stable coronary or peripheral artery disease who were randomized to receive rivaroxaban 2.5 mg bid plus ASA 100 mg daily, rivaroxaban 5 mg bid, or ASA 100 mg daily. Patients studied required a surgery/procedure during the trial...

INTRODUCTION: Rotational atherectomy (RA) presents superior efficacy over traditional balloon angioplasty in managing calcified plaques, albeit being associated with a perceived heightened aggressiveness and increased risk of periprocedural complications. AIM: To assess the frequency and predictive factors of periprocedural myocardial infarction (MI) following RA. MATERIAL AND METHODS: This was a retrospective observational study, encompassing 534 patients...

AIMS: Many cardiovascular events occur in seemingly healthy individuals.We set out to assess the predictive value of atherosclerosis imaging in combination with cardiovascular risk calculators in subjects aged 40-65 years. METHODS: We compared PROCAM (PROspective CArdiovascular Münster study), SCORE (Systematic COronary Risk Evaluation) and SCORE2 with carotid ultrasound (total plaque area, TPA) in subjects without cardiovascular disease. In this prospective cohort study, follow-up was obtained by phone or mail from patients; or from clinical records, if needed...

BACKGROUND: Syphilis, owing to its natural course, can lead to long-term damage to the aortic valve, such as insufficiency and rarely stenosis, ostial coronary stenosis, and syphilitic aortitis. Cardiovascular involvement alongside neurological involvement dominates the prognosis. This should no longer be seen, thanks to awareness and prevention programmes, medical treatment, and antibiotics. CASE SUMMARY: We report a case of a 54-year-old chronic smoker with no previous history, admitted for respiratory distress amid an impaired general condition...

BACKGROUND: Diabetes may be associated with differential outcomes in patients undergoing left main coronary revascularization with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). The aim of this study was to investigate outcomes in patients with left main disease with and without diabetes undergoing PCI versus CABG. METHODS: Individual patient data were pooled from 4 trials (SYNTAX [TAXUS Drug-Eluting Stent Versus Coronary Artery Bypass Surgery for the Treatment of Narrowed Arteries], PRECOMBAT [Bypass Surgery Versus Angioplasty Using Sirolimus-Eluting Stent in Patients With Left Main Coronary Artery Disease], NOBLE [PCI vs...

BACKGROUND: The factors that determine the necessity of coronary artery revascularization in patients with unstable angina (UA) have been supported by limited data. Therefore, this study aimed to identify the predictors of revascularization in patients with UA. METHODS: The study included the recorded data of 3668 patients with UA who underwent cardiac catheterization (age 66 ± 9.2, men 70%); 2615 of them (71%) underwent revascularization (percutaneous transluminal coronary angioplasty (PTCA), coronary artery bypass graft (CABG), or hybrid revascularization...

Patients with peripheral arterial disease (PADs), undergoing percutaneous coronary intervention (PCI), have higher adverse event risks. The effect of invasiveness of PADs treatment on PCI outcome is unknown. This study assessed the impact of the invasiveness of previous PADs treatment (invasive or non-invasive) on event risks after PCI with contemporary drug-eluting stents. This post-hoc analysis pooled 3-year patient-level data of PCI all-comer patients living in the eastern Netherlands, previously treated for PADs...

Porcelain aorta, characterized by extensive calcification of the aortic wall is often associated with coronary calcification. It can pose an increased risk of thromboembolic complications during interventional and surgical procedures. We present a case of a 52-year-old female, a chronic smoker with dyslipidemia with complaints of exertional chest pain for past 6 months. She was diagnosed as a case of non-ST elevation myocardial infarction (NSTEMI) with multivessel CAD, with porcelain aorta and calcified coronaries based on abnormal ECG, elevated troponin and coronary angiography findings...

Objective: To analyze the diagnosis and surgical treatment of high-risk anomalous aortic origin of coronary artery (AAOCA). Methods: This study was a retrospective case series. From January 2016 to July 2023, 24 cases of high-risk AAOCA underwent surgical treatment in Department of Cardiac Surgery, Guangdong Provincial People's Hospital. There were 18 males and 6 females, operatively aged ( M (IQR)) 13 (26) years (range: 0.3 to 57.0 years). They were confirmed by cardiac ultrasound and cardiac CT, all of which had anomalous coronary running between the aorta and the pulmonary artery...

BACKGROUND: Numerous complications, such as postoperative arrhythmia and stroke, have been observed following coronary artery bypass graft (CABG) surgery. AIMS: This study sought to examine the impact of aging on the incidence of post-coronary artery shunt complications. OBJECTIVES: Aging is a physiological process experienced by every living cell, beginning early in development. Age plays a crucial role in determining postoperative complications, including those related to CABG...

BACKGROUND: Multivessel disease (MVD) is diagnosed in a fair number of patients with acute coronary syndrome (ACS). There are 36 cardiac-surgery (CS) centres and 157 catheterization laboratories dedicated to treat ACS in Poland. The aim of the study was to analyze MVD patient outcomes presented with ACS in centers with or without CS on-site. METHODS: The present study is a retrospective analysis (2017-2020) of MVD ACS patients (n = 4618) outcomes between those treated in centers with CS on site (n = 595) and those without CS (n = 4023)...

BACKGROUND: Although target lesion revascularization (TLR) after percutaneous coronary intervention (PCI) for unprotected left main coronary artery (LMCA) disease is not rare, its timing of occurrence and prognostic impact on long-term mortality is uncertain. OBJECTIVES: This study sought to investigate TLR incidence over time and its impact on mortality after PCI with drug-eluting stents (DES) for LMCA disease. METHODS: Using a pooled data from 4 multicenter observational registries (IRIS-DES [Interventional Cardiology Research Incorporation Society-Drug-Eluting Stents], IRIS-MAIN [Interventional Cardiology Research Incorporation Society-Left MAIN Revascularization], MAIN-COMPARE [Revascularization for Unprotected Left Main Coronary Artery Stenosis: Comparison of Percutaneous Coronary Angioplasty Versus Surgical Revascularization], and PRECOMBAT [PREmier of Randomized COMparison of Bypass Surgery versus AngioplasTy Using Drug-Eluting Stent in Patients with Left Main Coronary Artery Disease]), we evaluated 1,397 patients with LMCA disease treated with DES and available long-term mortality data...

UNLABELLED: A young female patient with Takayasu arteritis presented with unstable angina due to bilateral coronary artery involvement. Steroid pulse therapy and subsequent prednisolone administration were started, but early coronary artery bypass grafting was required because of the multiple angina attacks at rest, with a prednisolone dose of 22.5 mg (0.45 mg/kg/day). Since the left internal thoracic artery which was grafted to the left anterior descending artery resulted in graft failure a few days after the surgery, the immunosuppressive therapy was intensified with the addition of tocilizumab and methotrexate...

INTRODUCTION: Isolated coronary ostial stenosis of both ostia is a rare, potentially life-threatening condition, occurring in 0.1%-0.2% of patients undergoing coronary angiography. CASE REPORT: We present a case of a 69-year-old woman with a past medical history of breast cancer, who had been treated with radiotherapy, which most likely caused significant stenosis of both coronary ostia and likely accelerated aortic stenosis. Surgical angioplasty with autopericardium patch reconstruction of the left main coronary artery and right coronary arteries due to proximal stenotic disease was performed instead of venous or arterial bypasses with concomitant aortic valve replacement...

BACKGROUND: Previous reports have revealed various endovascular intervention techniques for prosthetic femoropopliteal bypass occlusion (PFPBO); however, treatment for PFPBO remains challenging for most interventionalists and vascular surgeons because the procedure is complicated. Most of the reported techniques involve device implantation. In the present study, we performed a combination of surgical graft thrombectomy and drug-coated balloon angioplasty for PFPBO without implanting any additional devices...

BACKGROUND: Stent thrombosis is a potentially lethal complication of coronary angioplasty and responsible for 20% of all post-angioplasty myocardial infarctions. Unusual causes may be overlooked and difficult to identify. CASE SUMMARY: A 70-year-old male with history of triple aortocoronary bypass presented with acute inferolateral ST-segment elevation myocardial infarction (STEMI). Critical stenosis of the vein graft to the right coronary artery was revealed, and with the use of distal embolic protection device, successful angioplasty with stent was performed under double antiplatelet treatment with aspirin and ticagrelor...

We present a rare case in which a 63-year-old male with a history of hypertension, diabetes mellitus, hyperlipidemia, and previous coronary artery bypass graft (CABG) presented with bilateral external iliac artery near occlusion. We describe the utilization of lithotripsy balloon angioplasty as opposed to the traditional double-barrel stenting method or modified endovascular repair (EVAR) to treat the occlusion. Pre-operative computed tomography (CT) angiography demonstrated a 90 percent occlusion of both the distal aorta and right external iliac artery, and 99 percent occlusion of the left external iliac...

Complex bifurcation lesions often requiring a two-stent revascularization approach mean more metal, a higher risk of major adverse cardiovascular events, and added difficulties in the case of late complications, such as in-stent restenosis and stent thrombosis. In this article, we report a case of late stent thrombosis in a 56-year-old patient who had left main (LM) and left anterior descending (LAD) left circumflex arteries with T and small protrusion technique percutaneous intervention (PCI) one year before her admission with hemodynamic compromise and no access to urgent coronary artery bypass grafting (CABG)...

PURPOSE: To describe the intraoperative use of bivalirudin during lower extremity revascularization in the setting of heparin-induced thrombocytopenia (HIT). CASE SUMMARY: A 65 year-old man presented with left common iliac, external iliac, and femoral artery occlusion necessitating revascularization with left femoral endarterectomy and common and external iliac stent angioplasty. Three months before the femoral endarterectomy, the patient was hospitalized for a coronary artery bypass procedure...

BACKGROUND: Coronary artery dissection is a feared and potentially life-threatening complication of percutaneous coronary intervention (PCI). METHODS: We examined the clinical, angiographic, and procedural characteristics, and outcomes of coronary dissection at a tertiary care institution. RESULTS: Between 2014 and 2019, unplanned coronary dissection occurred in 141 of 10,278 PCIs (1.4%). Median patient age was 68 (60, 78) years, 68% were men, and 83% had hypertension...
