BACKGROUND: Coronary artery disease (CAD) is one of the main causes of sudden death, but its exact pathogenesis requires further study. Thus, this study aimed to explore the immune and oxidative stress-related factors in CAD progression and their roles in CAD diagnosis. METHODS: Bioinformatics analysis was used in this study, and the GSE23561 dataset (training set) we used contained the transcriptome sequencing results of six CAD peripheral blood samples and nine control samples...

BACKGROUND: Postoperative delirium (POD) and neurological dysfunction are very common following cardiac surgery and deteriorate the patient's prognosis and the outcome of surgical procedures. A clinically effective management strategy or drug is not yet available for POD. Additionally, it is unknown whether remote ischemic preconditioning (RIPC) has neuroprotective and anti-delirium benefits in patients who undergo cardiac surgery. METHODS: This study examined whether RIPC can improve POD and neurological function in cardiac surgery patients...

BACKGROUND: Although the research on gender in acute type A aortic dissection (AAAD) patients has increased in recent years, the results are still controversial. The effect of time of onset on in-hospital mortality in patients with AAAD of different gender is unclear. The purpose of this study was to investigate the effect of onset time on in-hospital mortality of patients with AAAD of different gender. METHODS: In this retrospective observational study, patients with AAAD were selected from June 2013 to March 2020...

BACKGROUND: To retrospectively study the experience with application of no-touch technique in radial artery (RA)-based coronary artery bypass grafting (CABG). METHODS: Clinical data of patients who underwent RA-based multi- (n = 45) or full-arterial CABG (n = 27) between January 2019 and June 2022 in the Affiliated Hospital of ZunYi Medical University were collected. The incidence of main cardiovascular events at 30-day follow-up, the antebrachial union condition and the vessel patency rate were analyzed...

BACKGROUND: To compare the outcomes of two Thoracic Endovascular Aortic Repair (TEVAR) techniques of Left Subclavian Artery (LSA) reconstruction for Stanford Type B Aortic Dissection (TBAD) patients with undesirable proximal anchoring zone. METHODS: We retrospectively reviewed 57 patients with TBAD who underwent either three dimensional (3D)-printing-assisted extracorporeal fenestration (n = 32) or conventional extracorporeal fenestration (n = 25) from December 2021 to January 2023...

BACKGROUND: The cardio-renal syndrome and hepatic impairment play a critical role in end-stage heart failure (HF). Levosimendan is an effective inotropic agent used to maintain cardiac output similar to classic cardiotonic like dobutamine/dopamine. This current research aims to investigate the clinical outcomes of levosimendan and dobutamine/dopamine in Chinese heart transplant awaiting patients with severe hepatic or renal impairment. METHODS: We performed a retrospective analysis of 568 heart transplant awaiting individuals with severe hepatic or renal impairment who treated with levosimendan or dobutamine/dopamine in our institution between January 2015 and December 2020...

BACKGROUND: High rates of mortality and aortic arch stenosis have been reported for one-stage radical surgery of interruption of aortic arch (IAA) with ventricular septal defect (VSD) and other associated intracardiac defects, but the sample size of the study is relatively small, and the credibility of the study is not high. The risk factors of death and aortic arch stenosis will be analyzed in a large sample size of infants with IAA, VSD and other associated intracardiac defects after one-stage radical resection...

BACKGROUND: The prevalence of heart failure is constantly increasing in both children and adults. End-stage heart failure in children unresponsive to medical therapy has limited treatment options. Surgical options include heart transplantation or implantation of durable ventricular assist devices (VADs). To start the VAD program, it was necessary to train core team members, invite experienced proctors and adjust the organizational approach. METHODS: We present our first seven pediatric patients who underwent a VAD implantation with primary indication end-stage dilated cardiomyopathy...

Brucellosis endocarditis is a rare but life-threatening complication of brucellosis, involving congenital, prosthetic and even native valves. Its diagnosis and treatment is a great challenge for doctors. The patient's prognosis requires prompt diagnosis and continuous evaluation of treatment plans to assess the need for either surgical intervention of the infected valves or continuation of antibiotic therapy alone. We present a patient with brucellosis endocarditis, predominantly involving the mitral valve, presenting with vegetations and prolapse of the anterior leaflet of the mitral valve with moderate to severe regurgitation...

A 56-year-old woman was admitted to our hospital with a 2-week history of chest tightness and fatigue, and an echocardiogram revealed a massive polyserous cavity effusion. A massive (13.5 cm maximum diameter) intrapericardial mass was discovered using computed tomography (CT) and cardiovascular magnetic resonance imaging (MRI) in the ascending aortic wall. A pericardial biopsy was performed and diagnosed as a solitary fibrous tumor (SFT). After successful mass resection, an immunohistochemical test was positive for CD34, STAT-6, CD34, and Bcl2, which indicates a giant benign solitary fibrous tumor of the ascending aortic wall...

For patients with cardiogenic shock, delaying surgery with mechanical circulatory support is reported to yield better outcomes than emergency surgery. We report on an 82-year-old man diagnosed with vertebral osteomyelitis with concomitant infective endocarditis. Chest radiographs revealed a growing abscess, which resulted in an aorto-right ventricular fistula. Providing Impella support allowed for hemodynamic stabilization prior to surgery. The patient had an uneventful postoperative course and reported to be well in a follow-up 1 year later...

BACKGROUND: Thoracic endovascular aortic repair is a relatively new technique relative to open surgery, and our aim was to assess whether there is a difference in the risk of common postoperative complications between thoracic endovascular aortic repair and open surgery. METHODS: The PubMed, Web of Science, and Cochrane library were systematically searched for trials comparing thoracic endovascular aortic repair and open surgical repair from January 2000 to September 2022...

Emboli caused by cardiac myxomas mostly occur in the cardiovascular or cerebrovascular systems and rarely in the lower extremity vasculature. We introduce the rare case of a patient with left atrial myxoma (LAM) whose right lower extremity (RLE) suffered from acute ischemia due to tumor fragments, along with a review of the relevant literature, and highlight the clinical characteristics of LAM. An 81-year-old female presented with acute ischemia of RLE. Color Doppler ultrasound showed no blood flow signal far from the RLE femoral artery...
