RESUMO

BACKGROUND: Higher levels of inflammatory biomarkers are associated with an increased risk of perioperative atrial fibrillation and myocardial injury after non-cardiac surgery (MINS). Colchicine is an anti-inflammatory drug that might reduce the incidence of these complications. METHODS: COP-AF was a randomised trial conducted at 45 sites in 11 countries. Patients aged 55 years or older and undergoing major non-cardiac thoracic surgery were randomly assigned (1:1) to receive oral colchicine 0·5 mg twice daily or matching placebo, starting within 4 h before surgery and continuing for 10 days. Randomisation was done with use of a computerised, web-based system, and was stratified by centre. Health-care providers, patients, data collectors, and adjudicators were masked to treatment assignment. The coprimary outcomes were clinically important perioperative atrial fibrillation and MINS during 14 days of follow-up. The main safety outcomes were a composite of sepsis or infection, and non-infectious diarrhoea. The intention-to-treat principle was used for all analyses. This trial is registered with ClinicalTrials.gov, NCT03310125. FINDINGS: Between Feb 14, 2018, and June 27, 2023, we enrolled 3209 patients (mean age 68 years [SD 7], 1656 [51·6%] male). Clinically important atrial fibrillation occurred in 103 (6·4%) of 1608 patients assigned to colchicine, and 120 (7·5%) of 1601 patients assigned to placebo (hazard ratio [HR] 0·85, 95% CI 0·65 to 1·10; absolute risk reduction [ARR] 1·1%, 95% CI -0·7 to 2·8; p=0·22). MINS occurred in 295 (18·3%) patients assigned to colchicine and 325 (20·3%) patients assigned to placebo (HR 0·89, 0·76 to 1·05; ARR 2·0%, -0·8 to 4·7; p=0·16). The composite outcome of sepsis or infection occurred in 103 (6·4%) patients in the colchicine group and 83 (5·2%) patients in the placebo group (HR 1·24, 0·93-1·66). Non-infectious diarrhoea was more common in the colchicine group (134 [8·3%] events) than the placebo group (38 [2·4%]; HR 3·64, 2·54-5·22). INTERPRETATION: In patients undergoing major non-cardiac thoracic surgery, administration of colchicine did not significantly reduce the incidence of clinically important atrial fibrillation or MINS but increased the risk of mostly benign non-infectious diarrhoea.

RESUMO

OBJECTIVES: Sternotomy pain is common after cardiac surgery. The deep parasternal intercostal plane (DPIP) block is a novel technique that provides analgesia to the anterior chest wall. The aim of this study was to investigate the analgesic effect of bilateral DPIP blocks on intraoperative pain control in cardiac surgery. DESIGN: This is a double-blinded, prospective randomized controlled trial (Oct 2020-Dec 2022). SETTINGS: This study was conducted in a single institution, which is an academic university hospital. PARTICIPANTS: Eighty-six elective cardiac surgical patients with median sternotomy were recruited. INTERVENTIONS: Patients were randomly divided into DPIP or control group. Either 20ml 0.25% levobupivacaine or 0.9% normal saline was injected for the DPIP under ultrasound guidance after induction of general anaesthesia. MEASUREMENTS AND MAIN RESULTS: The primary outcome was intraoperative opioids consumption and hemodynamic changes at sternotomy. Secondary outcomes included postoperative morphine consumption, postoperative pain and time to tracheal extubation. Intraoperative opioids requirement was reduced from a median (IQR) intravenous morphine equivalence of 21.4mg (13.8-24.3mg) in control group to 9.5mg (7.3-11.2mg) in the DPIP group (P<0.001). Hemodynamic parameters were more stable in DPIP group at sternotomy, as evidenced by lower percentage increase in systolic, diastolic and mean arterial blood pressure from baseline. No difference was observed in time to tracheal extubation, postoperative morphine consumption, postoperative pain score and spirometry. CONCLUSIONS: Bilateral DPIP block provides effective intraoperative analgesia and opioid-sparing. It may be included as part of the multimodal analgesia for enhanced recovery in cardiac surgery.

RESUMO

BACKGROUND: Acute type B aortic dissection (TBAD) is a rare disease that is likely under-diagnosed in the UK. As a progressive, dynamic clinical entity, many patients initially diagnosed with uncomplicated TBAD deteriorate, developing end-organ malperfusion and aortic rupture (complicated TBAD). An evaluation of the binary approach to the diagnosis and categorisation of TBAD is needed. METHODS: A narrative review of the risk factors predisposing patients to progression from unTBAD to coTBAD was undertaken. RESULTS: Key high-risk features predispose the development of complicated TBAD, such as maximal aortic diameter > 40 mm and partial false lumen thrombosis. CONCLUSION: An appreciation of the factors that predispose to complicated TBAD would aid clinical decision-making surrounding TBAD.

RESUMO

INTRODUCTION: Open surgery is the gold standard treatment for aortic arch disease. However, due to its complexity, open arch replacement is associated with considerable risk of mortality and morbidity. METHOD: We report a case of a 71-year-old gentleman with multiple comorbidities and symptomatic 7 cm aortic arch aneurysm who was treated with a single-stage carotid-carotid and left carotid-axillary bypass followed by zone 0 aortic arch stenting with bimodular Nexus™ stent graft. RESULTS: Post-operatively, the patient suffered from a minor stroke with full neurological recovery. Follow-up computed tomography of the aorta 3 years post-stenting showed excellent stent position with no endoleak and complete resolution of the saccular aneurysm. DISCUSSION: The midterm result of our patient who was successfully treated with an off-the-shelf single branch, bimodular stent graft system is excellent with complete resolution of the arch saccular aneurysm at 3-year after the operation.

RESUMO

BACKGROUND: Acute type B aortic dissection (TBAD) is a rare condition that can be divided into complicated (CoTBAD) and uncomplicated (UnCoTBAD) based on certain presenting clinical and radiological features, with UnCoTBAD constituting the majority of TBAD cases. The classification of TBAD directly affects the treatment pathway taken, however, there remains confusion as to exactly what differentiates complicated from uncomplicated TBAD. AIMS: The scope of this review is to delineate the literature defining the intervention parameters for UnCoTBAD. METHODS: A comprehensive literature search was conducted using multiple electronic databases including PubMed, Scopus, and EMBASE to collate and summarize all research evidence on intervention parameters and protocols for UnCoTBAD. RESULTS: A TBAD without evidence of malperfusion or rupture might be classified as uncomplicated but there remains a subgroup who might exhibit high-risk features. Two clinical features representative of "high risk" are refractory pain and persistent hypertension. First-line treatment for CoTBAD is TEVAR, and whilst this has also proven its safety and effectiveness in UnCoTBAD, it is still being managed conservatively. However, TBAD is a dynamic pathology and a significant proportion of UnCoTBADs can progress to become complicated, thus necessitating more complex intervention. While the "high-risk" UnCoTBAD do benefit the most from TEVAR, yet, the defining parameters are still debatable as this benefit can be extended to a wider UnCoTBAD population. CONCLUSION: Uncomplicated TBAD remains a misnomer as it is frequently representative of a complex ongoing disease process requiring very close monitoring in a critical care setting. A clear diagnostic pathway may improve decision making following a diagnosis of UnCoTBAD. Choice of treatment still predominantly depends on when an equilibrium might be reached where the risks of TEVAR outweigh the natural history of the dissection in both the short- and long-term.

RESUMO

BACKGROUND: Novel clinical challenges are faced by cardiac surgeons under the coronavirus disease 2019 (COVID-19) pandemic. Amidst the uncertainties faced due to the socioeconomic and public health impact, there is little evidence surrounding COVID-19 vaccination in patients undergoing cardiac surgery. Timing of vaccination and postvaccination adverse effects are required parameters to discuss with cardiac surgical patients. METHODS: This is a single-center, retrospective observational study. All patients who underwent adult cardiac surgery at the Prince of Wales Hospital, Hong Kong from January 2021 to December 2021 were included. Postoperative clinical outcomes, COVID-19 vaccination status, and vaccination-related adverse effects were collected. RESULTS: A total of 426 patients; 117 (27%) underwent isolated coronary artery bypass grafting, 111 (26%) underwent valvular surgery, and 97 (23%) underwent aortic surgery. Patients received either Sinovac CoronaVac or Pfizer BNT162b2 vaccine. Overall vaccination rate with at least 1 dose was 52% (n = 212), 15% (n = 63) received the first dose before surgery, 36% (n = 149) received the first dose vaccination after surgery. Rate of completion with second and third doses of vaccination were 22% (n = 89) and 4.9% (n = 20), respectively. The mean timing of first dose of vaccine after surgery was 216 ± 84 days from operation. Three (1.4%) patients recorded vaccination-related complications. CONCLUSIONS: COVID-19 vaccination is safe in patients who received major cardiac surgery, with low adverse effects recorded and no vaccine-related mortality observed. A time frame of 3-6 months after cardiac surgery receiving COVID-19 vaccination is reasonable and could serve as a guidance for future COVID-19 vaccination booster programs.

RESUMO

BACKGROUND: Despite significant advancements in operative techniques and myocardial protection, triple valve surgery (TVS) remains a formidable operation with a relatively high in-hospital mortality. We evaluated the prognostic value of Model for End-stage Liver Disease score including sodium (MELD-Na) for mortality after TVS and its predictive value when incorporated in the EuroSCORE risk model. METHODS: We performed a retrospective cohort study of 61 consecutive patients who underwent TVS from November 2005 to June 2016. Demographics, clinical, biochemical, and operative data were collected and analyzed. RESULTS: Median follow-up duration was 8.0 years. The majority (70.5%) of patients suffered from rheumatic heart disease and underwent mechanical double valve replacement with tricuspid valve repair. There were six operative deaths (9.84%), with the most common cause of death being multiorgan failure (83.3%). In 26.2% of the cohort, the MELD-Na score was moderately elevated at 9 to 15. A small fraction (4.9%) had a severely elevated MELD-Na greater than 15. Patients with a MELD-Na greater than 9 had a higher unadjusted rate of operative mortality, prolonged ventilation, need for dialysis and acute liver failure after TVS. Hierarchical logistic regression was performed using logistic EuroSCORE as the base model. After risk adjustment, each point of MELD-Na score increase was associated with 1.405 times increase in odds of operative mortality. The regression analysis was repeated by incorporating individual components of the MELD-Na score, including bilirubin, sodium, and albumin. All three biochemical parameters were significantly associated with operative mortality CONCLUSION: MELD-Na score as a quantifier of hepatorenal dysfunction is sensitive and specific for operative mortality after triple valve surgery.

RESUMO

BACKGROUND AND AIM: The Valiant NavionTM stent graft system is a third-generation low profile thoracic endograft designed for thoracic endovascular aortic repair. In this population analysis, we report on the first Asian all-comers experience and outcomes who underwent thoracic endovascular aortic repair with the use of this new stent graft system. METHODS: Between May 2019 and October 2020, 21 patients with different aortic pathologies were prospectively recruited and retrospectively analyzed. Important clinical and device-related outcomes were evaluated. The endpoints included short-term survival, technical success, access failures, major vascular and clinical complications, endoleaks, and hospital stay. RESULTS: The commonest indication of stenting was penetrating aortic ulcers (28.6%) and six (28.6%) patients had emergency stenting performed for aortic transection or rupture. 30 days of survival postprocedure was recorded and complete. There were no major vascular complications. Deployment accuracy was 100%, and the technical success rate was 94.7% (18/19) with one patient having a Type 2 endoleak on follow-up imaging. No neurological complications were noted. The mean operative time was 95 ± 73.6 min and the mean fluoroscopy time was 16.2 ± 10.8 min. Mean hospital stay for elective zone 2, 3, and 4 stenting was 5.3 ± 3.8 days, and only one patient postzone 1 thoracic endovascular aortic repair required a brief (0.5 days) ICU stay. All procedures were performed via the percutaneous transfemoral route with 100% success in percutaneous closure. CONCLUSION: This first reported Asian case series demonstrated versatility, safety, and efficacy of the Valiant NavionTM stent in Asian patients with different aortic pathologies.

RESUMO

Background Video-assisted thoracic surgery (VATS) for major lung resection has undergone major changes from three or four-port approach to the recently possible single-port VATS approach. Outcomes following single-port VATS major lung resection are analyzed to determine safety and efficacy. Methods A prospective database of 150 consecutive patients who underwent single-port VATS major lung resection between March 2012 and January 2014 was reviewed. Patient demographics, perioperative parameters, histopathology, and outcomes up to follow-up of 2 years were analyzed by descriptive and Kaplan-Meier survival statistics. Results Single-port VATS major lung resection was successfully performed in 142 patients (conversion rate 5.3%) for both malignant and benign diseases of the lung. Overall, 130 patients (87%) had nonsmall-cell lung carcinoma (NSCLC), 9 (6%) had other types of primary lung cancer, and the remaining for secondary malignancies and benign diseases. Among the 130 patients with NSCLC, 93 (71.5%) were stage I, 28 were stage II (21.5%), and 9 (7%) were stage III or greater. There was no intraoperative or 30-day mortality. However, one perioperative death occurred on day 49, and another on day 60 postoperatively due to infective causes. The overall 2-year mortality rate for all patients was 3%. The disease-free survival rate for subgroups, stage I NSCLC, and stage II or greater NSCLC were 96 and 83%, respectively. Conclusions Single-port VATS major lung resection for malignant and benign lung diseases is associated with low perioperative morbidity and mortality. Disease-free survival rates for NSCLC are acceptable and comparable with conventional VATS.

RESUMO

BACKGROUND: Few data exist on the relation of the 3-dimensional morphology of mitral valve and degree of mitral regurgitation (MR) in mitral valve prolapse. METHODS AND RESULTS: Real-time 3-dimensional transesophageal echocardiography of the mitral valve was acquired in 112 subjects, including 36 patients with mitral valve prolapse and significant MR (≥3+; MR+ group), 32 patients with mitral valve prolapse but no or mild MR (≤2+; MR- group), 12 patients with significant MR resulting from nonprolapse pathologies (nonprolapse group), and 32 control subjects. The 3-dimensional geometry of mitral valve apparatus was measured with dedicated quantification software. Compared with the normal and MR- groups, the MR+ group had more dilated mitral annulus (P<0.0001), a reduced annular height to commissural width ratio (AHCWR) (P<0.0001) indicating flattening of annular saddle shape, redundant leaflet surfaces (P<0.0001), greater leaflet billow volume (P<0.0001) and billow height (P<0.0001), longer lengths from papillary muscles to coaptation (P<0.0001), and more frequent chordal rupture (P<0.0001). Prevalence of chordal rupture increased progressively with annulus flattening (7% versus 24% versus 42% for AHCWR >20%, 15%-20%, and <15%, respectively; P=0.004). Leaflet billow volume increased exponentially with decreasing AHCWR in patients without chordal rupture (r(2)=0.66, P<0.0001). MR severity correlated strongly with leaflet billow volume (r(2)=0.74, P<0.0001) and inversely with AHCWR (r(2)=0.44, P<0.0001). In contrast, annulus dilatation but not flattening occurred in nonprolapse MR patients. An AHCWR <15% (odds ratio=7.1; P=0.0004) was strongly associated with significant MR in mitral valve prolapse. CONCLUSION: Flattening of the annular saddle shape is associated with progressive leaflet billowing and increased frequencies of chordal rupture and may be important in the pathogenesis of MR in mitral valve prolapse.

RESUMO

The mitral valve (MV) has complex 3-dimensional (3D) morphology and motion. Advance in real-time 3D echocardiography (RT3DE) has revolutionized clinical imaging of the MV by providing clinicians with realistic visualization of the valve. Thus far, RT3DE of the MV structure and dynamics has adopted an approach that depends largely on subjective and qualitative interpretation of the 3D images of the valve, rather than objective and reproducible measurement. RT3DE combined with image-processing computer techniques provides precise segmentation and reliable quantification of the complex 3D morphology and rapid motion of the MV. This new approach to imaging may provide additional quantitative descriptions that are useful in diagnostic and therapeutic decision-making. Quantitative analysis of the MV using RT3DE has increased our understanding of the pathologic mechanism of degenerative, ischemic, functional, and rheumatic MV disease. Most recently, 3D morphologic quantification has entered into clinical use to provide more accurate diagnosis of MV disease and for planning surgery and transcatheter interventions. Current limitations of this quantitative approach to MV imaging include labor-intensiveness during image segmentation and lack of a clear definition of the clinical significance of many of the morphologic parameters. This review summarizes the current development and applications of quantitative analysis of the MV morphology using RT3DE.

RESUMO

PURPOSE: To describe the use of cerebral oximetry to detect a lack of right cerebral perfusion resulting from a malpositioned catheter used for antegrade cerebral perfusion during deep hypothermic circulatory arrest (DHCA). The simple corrective surgical adjustment that followed averted a potentially serious complication. CLINICAL FEATURES: A 57-yr-old male with a type-A aortic dissection undergoing DHCA required antegrade cerebral perfusion for cerebral protection. Catheters were placed accordingly in the left common carotid and brachiocephalic arteries. Whereas frontal cerebral oximetry immediately improved on the left, it did not improve on the right. It was immediately suspected that the tip of the brachiocephalic cannula had advanced into the right subclavian artery, thus depriving the right common carotid artery of blood flow. The problem resolved upon slight withdrawal of the cannula. CONCLUSION: Vigilance in anesthesia should not stop during DHCA or cardiopulmonary bypass. Cerebral oximetry may provide important information leading to actions that improve brain protection. Vigilances proved important in this case where the cannula tip used for antegrade cerebral perfusion was advanced too far into the right subclavian artery.

RESUMO

Background: Patent foramen ovale (PFO) has been associated with migraine, cryptogenic stroke (CS), and hypoxemia. However, which examination method is most reliable remains controversial. This study sought to investigate the diagnostic value of contrast-enhanced ultrasonography (cU), including contrast-enhanced transcranial Doppler (cTCD), contrast transthoracic echocardiography (cTTE), and contrast transesophageal echocardiography (cTEE), for PFO; and to determine the best diagnostic strategy. Methods: This retrospective observational study included a total of 147 consecutive patients suspected PFO at The First Hospital of Shanxi Medical University between October 2019 and January 2022. The patients also underwent cTCD, cTTE, and cTEE examinations. The standard for the diagnosis of PFO was confirmation of the presence of PFO by color Doppler flow signals or contrast microbubbles (MBs) passing through the foramen ovale. Results: A total of 123 patients were diagnosed with PFO and 24 patients without PFO during the study period. The detectable rates of cTCD, cTTE, and cTEE were 120 (97.56%), 110 (89.43%), and 121 (98.37%), respectively. The sensitivity between cTCD and cTEE for PFO were comparable [97.56%, 95% confidence interval (CI): 92.5% to 99.4% vs. 98.37%, 95% CI: 93.7% to 99.7%; P>0.99], and the sensitivity of both were higher than that of cTTE (89.43%, 95% CI: 82.3% to 94.0%; P=0.02 and P=0.001, respectively). In addition, the specificity of cTEE for PFO was significantly higher than that of cTCD (100%, 95% CI: 82.3% to 100.0% vs. 75.00%, 95% CI: 53.0% to 89.4%; P<0.001) and cTTE (100%, 95% CI: 82.3% to 100.0% vs. 75.00%, 95% CI: 53.0% to 89.4%; P<0.001). Further, the semi-quantitative classification ability of cTCD for PFO with right-to-left shunt (RLS) was significantly higher than that of cTTE and cTEE (P=0.02 and P<0.001, respectively), and that of cTTE was significantly higher than that of cTEE (P=0.01). The Spearman analysis showed that the degree of RLS was positively correlated with the inner diameter of the PFO (r=0.695, P<0.001). Conclusions: The combination of cTCD and cTEE may provide a favorable strategy for the diagnosis of PFO.

RESUMO

Background: Management of acute type A intramural hematoma (IMH) is a controversial topic, and variable treatment strategies have been reported. Upfront aortic replacement may not be necessary in all cases. The goal of our study was to evaluate clinical outcomes of patients with acute type A IMH or thrombosed false lumen (FL) treated with upfront surgery or watchful waiting. Methods: Patients admitted to our hospital with type A IMH or aortic dissection with thrombosed ascending FL from December 2012 to February 2023 were retrospectively reviewed. Results: Among the 93 patients with type A IMH, 36 (38.7%) patients underwent upfront aortic surgery (Group S), and 57 (61.3%) patients were offered watchful waiting with medical surveillance (Group W). Of the 57 patients in Group W, 32 were treated conservatively with medical therapy alone (Group C). Patients in Group S had larger ascending aortic diameter (47.8±5.3 vs. 44.4±4.2 mm: P=0.001), higher frequency of pericardial effusion (38.9% vs. 10.5%; P=0.001) and cardiac tamponade (16.7% vs. 1.8%; P=0.008). The overall mortality rate was 4.3% in the whole cohort over a median follow up of 40.5 months. Overall survival for Group S was 100% at 30 days and 1 year, and 96.2% at 5 years. Overall survival for Group W was 98.2% at 30 days, 96.3% at 1 year and 95.2% at 5 years. The difference in overall survival was not statistically significant (P=0.64). Overall survival for Group C was 100% at 30 days and 1 year, and 90.9% at 5 years. Conclusions: Survival outcomes in selected patients with type A IMH were satisfactory. An individualized approach to patients with uncomplicated type A IMH was feasible. Upfront surgery was not necessary in all cases.

RESUMO

OBJECTIVES: The aim of this multicentre study was to demonstrate the safety and clinical performance of E-vita OPEN NEO Stent Graft System (Artivion, Inc.) in the treatment of aneurysm or dissection, both acute and chronic, in the ascending aorta, aortic arch and descending thoracic aorta. METHODS: In this observational study of 12 centres performed in Europe and in Asia patients were enrolled between December 2020 and March 2022. All patients underwent frozen elephant trunk using E-vita OPEN NEO Stent Graft System. Primary end point was the rate of all-cause mortality at 30 days and secondary end points included further clinical and safety data are reported up to 3-6 months postoperatively. RESULTS: A total of 100 patients (66.7% male; mean age, 57.7 years) were enrolled at 12 sites. A total of 99 patients underwent surgery using the E-vita OPEN NEO for acute or subacute type A aortic dissection (n = 37), chronic type A aortic dissection (n = 33) or thoracic aortic aneurysm (n = 29), while 1 patient did not undergo surgery. Device technical success at 24 h was achieved in 97.0%. At discharge, new disabling stroke occurred in 4.4%, while new paraplegia and new paraparesis was reported in 2.2% and 2.2%, respectively. Renal failure requiring permanent (>90 days) dialysis or hemofiltration at discharge was observed in 3.3% of patients. Between discharge and the 3-6 months visit, no patients experienced new disabling stroke, new paraplegia or new paraparesis. The 30-day mortality was 5.1% and the estimated 6-month survival rate was 91.6% (standard deviation: 2.9). CONCLUSIONS: Total arch replacement with the E-vita OPEN NEO can be performed with excellent results in both the acute and chronic setting. This indicates that E-vita OPEN NEO can be used safely, including in the setting of acute type A aortic dissection.

RESUMO

Background: Syphilitic ostial coronary stenosis is an uncommon manifestation of cardiovascular syphilis, characterized by concomitant aortic regurgitation and isolated or bilateral ostial involvement. Although much has been written about syphilis in the pre-antibiotic era, the key imaging and operative findings were rarely reported in the modern literature. Through multimodality imaging and operative videos, we demonstrate the unique diagnostic and therapeutic hurdles associated with the condition. Case Description: A 47-year-old woman presented with acute decompensated heart failure due to bilateral ostial coronary stenosis and severe aortic insufficiency, which raises suspicion for underlying syphilis. She underwent successful aortic valve replacement, right coronary ostioplasty and bypass grafting of the left coronary system. The syphilitic process was confirmed by histopathological examination of the aortic valve and aortic wall as well as serological tests. She recovered from the operation uneventfully. Conclusions: The manifestations of cardiovascular syphilis are protean and can pose significant diagnostic challenges even in the modern era. The presence of isolated coronary ostial stenosis should raise suspicion for syphilis. Timely surgery and antibiotics can lead to successful outcomes. Furthermore, the evolution and nuances of surgical techniques addressing ostial coronary stenosis was reviewed. Surgical strategy should be individualized based on preoperative multimodality imaging.

RESUMO

Background and Objective: Thoracic aortic aneurysm and dissection (TAAD) and its complications are life-threatening conditions. Hypertension and atherosclerosis had all along been recognized as the predominant risk factors for the development of TAAD. However, it was increasingly reported that genetic factors, such as single nucleotide polymorphisms (SNPs), are playing an important role in the disease development. The development of next-generation sequencing (NGS) and the rapid growth in radiomics provide a promising new platform to evaluate genetically triggered thoracic aortic aneurysm and dissection (GTAAD) from a new angle. This review is to present an overview of currently available knowledge regarding the use of radiomics and radiogenomics in GTAAD. Methods: We performed literature searches in PubMed, EMBASE and Cochrane database from 2012 to 2022 regarding the use of radiomics and radiogenomics in GTAAD. Key Content and Findings: There were only 13 studies on radiomics and 4 studies on radiogenomics integration retrieved from the search and it signifies there is still a significant knowledge gap in this field of translational medicine. An overview of the current knowledge of GTAAD, the workflow and role of radiomics, the radiogenomics integration for GTAAD including its potential role in the development of polygenic scores, as well as the implications, challenges, and limitations of radiogenomics research were discussed. Conclusions: In the contemporary era, radiogenomics has been emerging as a state-of-the art approach to establish statistical correlation with radiomics features with genomic information in diagnosis, risk modeling and prediction and treatment decision in TAAD.
