Background: Percutaneous coronary intervention (PCI) has become one of the most commonly performed interventional life-saving procedures worldwide. Intravascular Imaging (intravascular ultrasound (IVUS) and optical coherence tomography (OCT)) have initially evolved to guide PCI compared with angiography. However, this technology is not universally employed in all PCI procedures, and there is ongoing controversy regarding its additional benefits to patient outcomes. We aim to estimate the efficacy and safety of imaging modalities during PCI, allowing pre-, per, and post-intervention assessment of coronary vascularization., Methods: A systematic review and Bayesian network meta-analysis of randomized controlled trials (RCTs), which were retrieved from PubMed, WOS, SCOPUS, EMBASE, and CENTRAL through September 2023. We used R, version 4.2.0. Effect sizes will be presented as odds ratios with accompanying 95% credible intervals., Prospero Id: CRD42024507821., Results: Our study, encompassing 36 RCTs with a total of 17,572 patients, revelead that compared to conventional angiography, IVUS significantly reduced the risk of major adverse cardiovascular events (MACE) (OR: 0.71 [95% CrI: 0.56 to 0.87]) but not OCT (OR: 0.91 [95% CrI: 0.62 to 1.39]), IVUS and OCT significantly reduced the risk of cardiac death (OR: 0.50 [95% CrI: 0.33 to 0.76]) and (OR: 0.55 [95% CrI: 0.31 to 0.98]), respectively, IVUS significantly reduced the risk of target vessel-related revascularization (OR: 0.60 [95% CrI: 0.48 to 0.75]) but not OCT (OR: 0.86 [95% CrI: 0.60 to 1.19]), IVUS and OCT significantly reduced the risk of stent thrombosis (OR: 0.50 [95% CrI: 0.28 to 0.92]) and (OR: 0.48 [95% CrI: 0.22 to 0.98]), respectively, IVUS significantly reduced the risk of re-stenosis (OR: 0.65 [95% CrI: 0.46 to 0.88]) but not OCT (OR: 0.55 [95% CrI: 0.15 to 1.99]), neither IVUS (OR: 0.97 [95% CrI: 0.71 to 1.38]) nor OCT (OR: 0.75 [95% CrI: 0.49 to 1.22]) were associated with statistically significant reductions in all-cause mortality, neither IVUS (OR: 0.70 [95% CrI: 0.45 to 1.32]) nor OCT (OR: 0.81 [95% CrI: 0.47 to 1.59]) were associated with statistically significant reductions in target vessel failure, neither IVUS (OR: 0.88 [95% CrI: 0.43 to 2.44]) nor OCT (OR: 0.81 [95% CrI: 0.37 to 2.04]) were associated with statistically significant reductions in target lesion failure, and neither IVUS (OR: 0.82 [95% CrI: 0.60 to 1.06]) nor OCT (OR: 0.84 [95% CrI: 0.59 to 1.19]) were associated with statistically significant reductions in myocardial infarction., Conclusion: Intravascular imaging-guided, including IVUS and OCT, improved the postinterventional outcomes of PCI, notably suggesting their advantage over traditional angiography with no significant difference between IVUS and OCT., (© 2024.

Objective: The evidence underlying the efficacy and safety of minimally invasive mitral valve surgery (MIMVS) is inconclusive. We conducted a meta-analysis to evaluate whether MIMVS improves clinical outcomes compared with conventional sternotomy., Methods: We searched MEDLINE (via PubMed), Embase, the Cochrane Library, and ClinicalTrials.gov from inception to January 2024 for all randomised controlled trials (RCTs), comparing MIMVS with conventional mitral valve surgery. RevMan 5.4 was used to analyse the data with risk ratio (RR) and mean difference (MD) as the effect measures., Results: Eight studies reporting data on 7 RCTs were included in our review. There was no significant difference in all-cause mortality, the number of patients requiring blood product transfusion, and the change from baseline in the SF-36 physical function scores between the MIMVS and conventional sternotomy groups. MIMVS reduced the length of hospital stay (MD -2.02 days, 95% CI: -3.66, -0.39) but did not affect the length of ICU stay, re-operation for bleeding, and the incidence of renal injury, wound infection, neurological events, and postoperative moderate or severe mitral regurgitation. MIMVS was associated with a trend toward lower postoperative pain scores (MD -1.06; 95% CI: -3.96 to 0.75)., Conclusions: MIMVS reduced the number of days spent in the hospital and showed a trend toward lower postoperative pain scores, but it did not decrease the risk of all-cause mortality or the number of patients needing blood product transfusions. Further large-scale RCTs are required to inform definitive conclusions, particularly with regard to quality-of-life outcomes investigating functional recovery., Systematic Review Registration: PROSPERO (CRD42023482122)., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Amin, Kumar, Mokhtassi, Alassiri, Odaman, Khan, Lakshmana, Din, Acharya, Cheema, Nashwan, Khan, Hussain, Bhudia and Vincent.)

Introduction: Deciding whether to perform coronary artery bypass grafting (CABG) alone or in combination with mitral valve repair is a common dilemma encountered by surgeons when treating patients with ischemic mitral regurgitation, a common condition related to coronary artery disease. Although ischemic mitral regurgitation after CABG has been linked to unfavorable results, the benefits of including mitral valve repair are still unknown. This discrepancy led us to undertake a systematic review and meta-analysis to determine whether combining CABG with mitral valve surgery leads to better clinical results than CABG alone., Evidence Acquisition: Studies comparing the results of CABG versus CABG with mitral valve replacement were searched in the databases of PubMed and Google Scholar. There were six randomized clinical trials included in this study., Evidence Synthesis: We analyzed 852 patients' data. There were no significant variations between patients who acquired CABG alone or CABG+(MVR) in terms of their risk of death at one year, stroke, atrial fibrillation, or hospitalization for heart failure. For recurrent/residual mitral regurgitation; it revealed an RR=5.42, 95% CI, 0.77 to 37.98, and a P value of =0.065. According to the analysis of study heterogeneity, no apparent heterogeneity was identified in the outcomes of death after one year, stroke, atrial fibrillation, or hospitalization for heart failure. However, the outcome of recurrent or residual mitral regurgitation showed significant variation (I 2 =66%)., Conclusions: Patients who underwent CABG alone versus CABG plus MVR did not differ significantly from one another. However, the comparison of CABG alone with CABG plus MVR underlines the need for customized treatment plans based on the unique characteristics of each patient.

Background: Extracorporeal membrane oxygenation (ECMO) has been presented as a potential therapeutic option for patients with cardiogenic shock complicating myocardial infarction (CS-MI). We aimed to investigate the efficacy and safety of ECMO in CS-MI., Methods: A systematic review and meta-analysis synthesizing evidence from randomized controlled trials obtained from PubMed, Embase, Cochrane, Scopus, and Web of Science until September 2023. We used the random-effects model to report dichotomous outcomes using risk ratio and continuous outcomes using mean difference with a 95% confidence interval. Finally, we implemented a trial sequential analysis to evaluate the reliability of our results., Results: We included four trials with 611 patients. No significant difference was observed between ECMO and standard care groups in 30-day mortality with pooled RR of 0.96 (95% CI: 0.81-1.13, p = 0.60), acute kidney injury (RR: 0.65, 95% CI: 0.41-1.03, p = 0.07), stroke (RR: 1.16, 95% CI: 0.38-3.57, p = 0.80), sepsis (RR: 1.06, 95% CI: 0.77-1.47, p = 0.71), pneumonia (RR: 0.99, 95% CI: 0.58-1.68, p = 0.96), and 30-day reinfarction (RR: 0.95, 95% CI: 0.25-3.60, p = 0.94). However, the ECMO group had higher bleeding events (RR: 2.07, 95% CI: 1.44-2.97, p < 0.0001)., Conclusion: ECMO did not improve clinical outcomes compared to the standard of care in patients with CS-MI but increased the bleeding risk., (© 2024.

Introduction: Postoperative complications pose significant challenges in cardiac surgery and with the evolution of selenium as a potential anti-inflammatory agent, some studies reported its inefficiency. Thus, we conducted our meta-analysis to evaluate the impact of selenium supplementation on cardiac surgery patients., Methods: Different databases such as PubMed, Embase, and Cochrane Library from inception till January 2024 were searched identifying a total of seven randomized-controlled trials involving selenium supplementation after cardiac surgery. Risk ratio (RR) and Mean difference (MD) were calculated with a 95% confidence interval (CI)., Results: The selenium intervention significantly raised the incidence of Acute Kidney injury (RR 0.76; 95% CI: 0.59, 0.98; P = 0.04) while significantly reducing the duration of hospital stay (MD -1.33; 95% CI: -2.51, -0.16; P = 0.03) and postoperative CRP levels (SMD -0.18; 95% CI: -0.34, -0.02; P = 0.03). The effect of selenium intervention on days spent in ICU (MD -0.01; 95% CI: -0.28, 0.25; P = 0.92), mortality (RR 1.07; 95% CI: 0.84, 1.37; P = 0.57) and incidence of hospital acquired infections (RR 0.98; 95% CI: 0.76, 1.26; P = 0.88) is insignificant., Conclusion: Selenium supplementation did not significantly reduce major postoperative complications in cardiac surgery patients. However, its ability to modulate inflammation, as reflected in decreased C-reactive protein levels, highlights its potential role in managing the inflammatory response. Future investigations should focus on optimized selenium supplementation strategies in conjunction with other antioxidants to enhance its benefits., (© 2024. The Author(s).)

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). Patients who underwent CABG at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia, between March 2015 and December 2021 were enrolled in this study. Overall, 275 participants were eligible for our study, of which 84 were found to be valid for analysis. Phone contacts were made directly with the patient after briefly explaining the study. Scores and clinical data were investigated using multivariable linear regression analysis., Results: Subscales of role limitations due to physical issues had the lowest mean scores, followed by vitality and general health (57.4 ± 44.7; 60.4 ± 25.6; 64.1 ± 22.6), respectively. However, social functioning (78.9 ± 29.0) and pain (75.1 ± 29.9) had the highest scores of all subscales. A history of congestive heart failure (CHF) was independently associated with lower scores for physical role limitations (p = 0.021), vitality (p = 0.001), general health (p< 0.001), and mental health (p = 0.011). Lower mental health scores were also predicted by being a widow (p = 0.030), whereas lower general health scores were predicted by being unemployed (p = 0.001) and having a peripheral vascular disease (PVD) (p = 0.043). Additionally, the development of postoperative complications was an independent predictor of lower physical functioning (p = 0.028) and vitality (p = 0.043). Regarding the number of grafts, cardiopulmonary bypass, and cross-clamp time, no significant impact was found on any of the SF-36 subscales (p> 0.05)., Conclusion: The postoperative decline in HRQoL was attributed to comorbidities such as CHF and PVD, postoperative complications including bleeding and wound infection, as well as unemployment and widowed status. Therefore, choosing the appropriate patients for surgery and post-discharge follow-up may enhance HRQoL., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Alzahrani et al.)

Objective: Cardiovascular disease is the leading cause of death globally, responsible for 17.5 million deaths each year, 80% of which occur in low- and middle-income countries, including countries in Africa. Cardiothoracic surgery, with its heavy financial outlay, is unavailable in many African countries. Many African healthcare givers are under the erroneous impression that the cardiovascular surgical landscape of Africa is blank. This review aims at describing the cardiothoracic surgery practice in Africa, the different training programs in the region, and its future prospects., Method: Through a literature review, the authors elaborate on key points, such as healthcare and cardiothoracic surgery in Africa, African cardiothoracic practice and training, and the future of cardiothoracic surgery in Africa., Results: African countries with established cardiothoracic surgery capacity and training programs still face several challenges across multiple levels, including a persistent low enrollment rate in residency programs, insufficient local expertise, a lack of financial resources, an inadequate health infrastructure, and a skewed health insurance reimbursement system. Thus, there is still a growing burden of surgically correctable cardiovascular disease in these countries., Conclusions: Cardiothoracic surgery in Africa has faced great challenges due to resource constraints, but it has demonstrated resilience and growth through diverse models and initiatives. The burden of cardiovascular diseases in Africa remains high, yet the capacity to provide cardiothoracic surgery is limited. With investment, support, and the implementation of comprehensive healthcare policies, cardiothoracic surgery practice can improve in this region and this can make a significant impact on the health and well-being of its population., Competing Interests: The authors reported no conflicts of interest. The Journal policy requires editors and reviewers to disclose conflicts of interest and to decline handling or reviewing manuscripts for which they may have a conflict of interest. The editors and reviewers of this article have no conflicts of interest., (© 2024 The Author(s).)

Background: Female sex is considered an independent predictor for mortality and morbidity following cardiac surgery. This study is to review the outcomes of adult cardiac surgery between males and females in a Saudi tertiary referral hospital., Method: This was a retrospective study for 925 adult patients operated on for ischemic coronary artery disease and acquired aortic and mitral valvular heart disease from 2015 to August 2023. We analyzed patient characteristics, intraoperative data, and postoperative results to compare outcomes between males and females., Results: Preoperative risk factors were not significantly different in both groups. Postoperative outcomes showed gender-based differences. In univariable analysis, females, compared to males, had significantly greater odds of prolonged postoperative ventilation (>24 hours), 32.8% of females compared to 20.7% of males (p < 0.001). Also, sternal wound infection was notably higher among females (13.3%) (p < 0.001). Mortality also exhibited a significant association, with 14.2% of females experiencing mortality compared to 9.4% of males (p = 0.049). In the multivariable analysis for elevated postoperative troponin, the use of pre-operative intra-aortic balloon pump, urgent/emergent surgery, elevated pre-operative troponin and combined bypass grafting with valve surgery, were also predictive of higher post-operative troponin concentrations (beta = 0.43, 95% CI: 0.25 to 0.62, p < 0.001)., Conclusion: Females in Saudi Arabia have an increased risk of short-term morbidity and mortality after cardiac surgery compared to males. Vague and delayed presentation and then the late diagnosis and referral are likely the main contributing factors. This highlights the need to implement preoperative measures to improve early diagnosis and referral to eliminate gender bias.

Background: Hypertension (HTN) is the most significant modifiable risk factor for cardiovascular disease (CVD) and overall mortality. HTN is defined as a systolic blood pressure of ≥140 mmHg and/or a diastolic blood pressure of ≥ 90 mmHg. Generally, arrhythmias are characterized by a disruption of the heart's regular rhythm. They are strongly associated with increased risks of CVDs and sudden death. The most common arrhythmia worldwide is atrial fibrillation (AF). HTN, diabetes mellitus (DM), and coronary artery disease (CAD) are major risk factors for arrhythmias., Objective: We aimed to identify the postoperative effects and risk factors of HTN and cardiac arrhythmia in patients who underwent cardiac surgery at King Abdulaziz University Hospital (KAUH) from 2015 to 2022., Methods: A retrospective record review was conducted by collecting data from KAUH electronic medical records. A total of 402 patients participated in this study. This study includes all hypertensive and arrhythmic patients who underwent cardiac surgeries., Results: Of the 402 patients studied, 209 had pre-operative HTN, and 47 had preoperative AF. Developing post-operative arrhythmia was found to significantly increase perioperative morbidity and mortality (p < 0.001). Risk factors for HTN and arrhythmia included increased age, higher BMI, and DM., Conclusion: The findings of this study suggest an association between preoperative HTN and AF and elevated rates of postoperative morbidity and mortality. AF emerged as the predominant arrhythmia type. It is advisable to optimize patients' health status prior to surgical procedures. Moreover, further research is recommended in this field to deepen our understanding of the perioperative implications of HTN and arrhythmias., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Bayazed et al.)
