ABSTRACT
OBJECTIVES: While significant evidence supports the benefits of normothermic cardiopulmonary bypass (NCPB) over hypothermic techniques, many institutions in developing countries, including ours, continue to employ hypothermic methods. This study aimed to assess the early postoperative outcomes of normothermic cardiopulmonary bypass (NCPB) for complete surgical repair via the Tetralogy of Fallot (TOF) within our national context. METHODS: We conducted this study in the Pediatric Cardiac Intensive Care Unit (PCICU) at the University Children's Hospital. One hundred patients who underwent complete TOF repair were enrolled and categorized into two groups: the normothermic group (n = 50, temperature 35-37 °C) and the moderate hypothermic group (n = 50, temperature 28-32 °C). We evaluated mortality, morbidity, and postoperative complications in the PCICU as outcome measures. RESULTS: The demographic characteristics were similar between the two groups. However, the cardiopulmonary bypass (CPB) time and aortic cross-clamp (ACC) time were notably longer in the hypothermic group. The study recorded seven deaths, yielding an overall mortality rate of 7%. No significant differences were observed between the two groups concerning mortality, morbidity, or postoperative complications in the PCICU. CONCLUSIONS: Our findings suggest that normothermic procedures, while not demonstrably effective, are safe for pediatric cardiac surgery. Further research is warranted to substantiate and endorse the adoption of this technique.

BACKGROUND: Cerebral perfusion may change depending on arterial cannulation site and may affect the incidence of neurologic adverse events in post-cardiotomy extracorporeal life support (ECLS). The current study compares patients' neurologic outcomes with three commonly used arterial cannulation strategies (aortic vs. subclavian/axillary vs. femoral artery) to evaluate if each ECLS configuration is associated with different rates of neurologic complications. METHODS: This retrospective, multicenter (34 centers), observational study included adults requiring post-cardiotomy ECLS between January 2000 and December 2020 present in the Post-Cardiotomy Extracorporeal Life Support (PELS) Study database. Patients with Aortic, Subclavian/Axillary and Femoral cannulation were compared on the incidence of a composite neurological end-point (ischemic stroke, cerebral hemorrhage, brain edema). Secondary outcomes were overall in-hospital mortality, neurologic complications as cause of in-hospital death, and post-operative minor neurologic complications (seizures). Association between cannulation and neurological outcomes were investigated through linear mixed-effects models. RESULTS: This study included 1897 patients comprising 26.5% Aortic (n = 503), 20.9% Subclavian/Axillary (n = 397) and 52.6% Femoral (n = 997) cannulations. The Subclavian/Axillary group featured a more frequent history of hypertension, smoking, diabetes, previous myocardial infarction, dialysis, peripheral artery disease and previous stroke. Neuro-monitoring was used infrequently in all groups. Major neurologic complications were more frequent in Subclavian/Axillary (Aortic: n = 79, 15.8%; Subclavian/Axillary: n = 78, 19.6%; Femoral: n = 118, 11.9%; p < 0.001) also after mixed-effects model adjustment (OR 1.53 [95% CI 1.02-2.31], p = 0.041). Seizures were more common in Subclavian/Axillary (n = 13, 3.4%) than Aortic (n = 9, 1.8%) and Femoral cannulation (n = 12, 1.3%, p = 0.036). In-hospital mortality was higher after Aortic cannulation (Aortic: n = 344, 68.4%, Subclavian/Axillary: n = 223, 56.2%, Femoral: n = 587, 58.9%, p < 0.001), as shown by Kaplan-Meier curves. Anyhow, neurologic cause of death (Aortic: n = 12, 3.9%, Subclavian/Axillary: n = 14, 6.6%, Femoral: n = 28, 5.0%, p = 0.433) was similar. CONCLUSIONS: In this analysis of the PELS Study, Subclavian/Axillary cannulation was associated with higher rates of major neurologic complications and seizures. In-hospital mortality was higher after Aortic cannulation, despite no significant differences in incidence of neurological cause of death in these patients. These results encourage vigilance for neurologic complications and neuromonitoring use in patients on ECLS, especially with Subclavian/Axillary cannulation.

BACKGROUND: Minimally invasive cardiac surgery (MICS) has garnered significant attention for its potential benefits, including decreased surgical trauma, accelerated recovery, and improved aesthetic outcomes. This case series aims to elucidate the technical aspects and assess the aesthetic, functional, and quality of life outcomes associated with the utilization of a periareolar incision approach in female patients undergoing cardiac surgery. METHODS: The periareolar MICS technique, performed with or without high-definition (HD) 3D endoscopic visualization, limited rib-spreading, and a periareolar incision spanning the 3 to 9 o'clock positions, was employed. We present a case series encompassing five female patients who underwent various cardiac procedures for different pathologies using this approach. RESULTS: No intraoperative complications occurred, and all patients experienced uneventful postoperative recoveries. The periareolar approach resulted in well-healed incisions with minimal scaring, preserving breast contour and yielding satisfactory cosmetic outcomes. Patients reported negligible pain levels and expressed contentment with the scar appearance. CONCLUSION: The periareolar incision technique in MICS represents an efficacious approach characterized by favorable aesthetic outcomes and enhanced patient experience. Further investigations are warranted to compare different MICS approaches with respect to pain management and their impact on quality-of-life domains.

Primary cardiac angiosarcoma is a rare, aggressive malignancy that commonly metastasizes to various organs. The presenting symptoms are typically nonspecific, so a comprehensive examination is required to confirm the diagnosis promptly. This case report describes the presentation of an older patient with a history of neoplasms. Echocardiography and biopsy were performed, but despite surgical intervention to resect a large right atrial mass, the patient died. A final diagnosis of primary angiosarcoma was made based on the resected specimen.

BACKGROUND: In cardiac surgical procedures, patients carrying high-risk profiles are prone to encompass complicated cardiopulmonary bypass (CPB) separation. Intraoperative transesophageal echocardiography (TEE), a readily available tool, is utilized to detect cardiac structural and functional pathologies as well as to facilitate clinical management of CPB separation, especially in the episodes of hemodynamic compromise. However, the conventional TEE examination, always performed in a liberal fashion without any restriction of view acquisition, is relatively time-consuming; there appear its flaws in the context of critically severe status. We therefore developed the perioperative rescue transesophageal echocardiography (PReTEE), a simplified three-view TEE protocol consisting of midesophageal four chamber, midesophageal left ventricular long axis, and transgastric short axis. METHODS: This is a single-center and randomized controlled trial which will be implemented in Peking Union Medical College Hospital, Beijing, China. A total of 46 TEE scans are schemed to be performed by 6 operators participating in and randomly assigned to either the PReTEE or the conventional TEE group. This study is purposed to investigate whether the efficiency of discriminating leading causes of difficult CPB wean-off can be significantly improved via an abbreviated sequence of TEE views. The primary outcome of interest is the difference between the groups of PReTEE and the conventional TEE in the successful discrimination of etiologies in specified 120 s. Cox proportional hazards model will be further employed to calculate the outcome difference. DISCUSSION: The estimated results of this trial are oriented at verifying whether a simplified TEE exam sequence can improve the efficiency of etiologies discrimination during CPB separation in cardiac surgery. TRIAL REGISTRATION: ClinicalTrials.gov NCT05960552. Registered on 6 July 2023.

OBJECTIVE: The impact of nitric oxide (NO) administered via cardiopulmonary bypass (CPB) on pediatric heart surgery remains controversial. The objective of this study is to conduct a comprehensive systematic review and meta-analysis to examine the impact of NO administered via CPB on pediatric heart surgery. METHODS: This study searched 7 electronic databases to identify Randomized Controlled Trials (RCTs) on the impact of NO administration during CPB on postoperative outcomes in pediatric heart surgery. The searched databases included Embase, Medline (though PubMed), Cochrane Library, Web of Science, Wan Fang database, China National Knowledge Infrastructure (CNKI), and ClinicalTrials.gov from their inception to November 2, 2022. The included RCTs compared NO administration during CPB with standard CPB procedures or placebo gas treatment in pediatric heart surgery. fixed-effects models and/or random-effects models were used to estimate the effect size with 95% confidence interval (CI). Heterogeneity among studies was indicated by p-values and I2. All analyses were performed using Review Manager software (version 5.4) in this study. RESULTS: A total of 6 RCTs including 1,739 children were identified in this study. The primary outcome was duration of postoperative mechanical ventilation, with the length of hospital and intensive care unit (ICU) stay as the second outcomes. Through a pooled analysis, we found that exogenous NO administered via CPB for pediatric heart surgery could not shorten the duration of postoperative mechanical ventilation when compared with the control group (standardized mean difference (SMD) -0.07, CI [-0.16, 0.02], I2 = 45%, P = 0.15). Additionally, there were also no difference between the two groups in terms of length of hospital stay (mean difference (MD) -0.29, CI [-1.03, 0.46], I2 = 32%, P = 0.45) and length of ICU stay (MD -0.22, CI [-0.49 to 0.05], I2 = 72%, P = 0.10). CONCLUSIONS: This meta-analysis showed that exogenous NO administration via CBP had no benefits on the duration of mechanical ventilation, the length of postoperative hospital, and ICU stay after pediatric heart surgery.

When faced with questions about artificial intelligence (AI), many surgeons respond with scepticism and rejection. However, in the realm of cardiac surgery, it is imperative that we embrace the potential of AI and adopt a proactive mindset. This systematic review utilizes PubMed® to explore the intersection of AI and cardiac surgery since 2017. AI has found applications in various aspects of cardiac surgery, including teaching aids, diagnostics, predictive outcomes, surgical assistance, and expertise. Nevertheless, challenges such as data computation errors, vulnerabilities to malware, and privacy concerns persist. While AI has limitations, its restricted capabilities without cognitive and emotional intelligence should lead us to cautiously and partially embrace this advancing technology to enhance patient care.

OBJECTIVE: Minimally invasive mitral valve surgery (mini-MVS) is typically reserved for patients who have not undergone open cardiac surgery. In the reoperative setting, using intrapericardial dissection for crossclamping the aorta through a minimally invasive approach can be difficult and, at times, risky. Cold fibrillatory cardiac arrest (CFCA) with systemic cardiopulmonary bypass without cross-clamping is a well-described technique; however, data about its safety for patients who undergo reoperative mini-MVS are limited. METHODS: Data for 34 patients who underwent reoperative mini-MVS with CFCA from March 2017 to March 2022 were reviewed retrospectively. A mini right thoracotomy (n = 30) or robotic (n = 4) approach was used. Systemic hypothermia was induced to a target temperature of 25 °C. RESULTS: Patient mean (SD) age was 64.5 (9.6) years, and 15 of 34 (44.1%) patients were women. Of those 34 patients, 23 (67.6%) had severe regurgitation, and 11 (32.4%) had severe stenosis. Before mini-MVS, 28 patients had undergone valve surgery, and 8 had undergone coronary artery bypass graft surgery. The mitral valve was repaired in 5 of 34 (14.7%) and replaced in 29 of 34 (85.3%) patients. No difference was observed in preoperative and postoperative left ventricular function (P = .82). In 1 patient, kidney failure developed that necessitated dialysis. No postoperative stroke or mortality at 30 days occurred. CONCLUSION: Mini-MVS with CFCA is well tolerated in patients with prior cardiac surgery. Myocardial function was not impaired, nor was the risk of stroke increased in this cohort, indicating that CFCA is a safe alternative in this high-risk population.

The tricuspid valve, long neglected as a passive structure and often termed the "forgotten valve", has recently gained attention from the international medical and cardiological community due to the association of tricuspid regurgitation with an unfavorable prognosis. Isolated tricuspid regurgitation represents a relatively unknown and variable condition, closely linked to the shape and function of the right ventricle and the state of the pulmonary circulation. Currently, guidelines are not clear regarding the optimal treatment strategy, the process of patient selection, and the surgical or transcatheter procedural timing, nor for predicting patient outcomes. Surgical procedures specifically aimed at correcting isolated tricuspid regurgitation, without other concomitant indications for open-heart surgery, have been considered complex and risky, with a high rate of postoperative complications and a poorly understood impact on patient survival and life expectancy. In this review, we will attempt to examine tricuspid valve pathology by analyzing preoperative assessment, essential for risk stratification, various surgical techniques, and outcomes.

Globally, more than one billion people are vulnerable to neglected tropical diseases, many of which have viral origins and cardiovascular implications. Access to cardiovascular care is limited in countries where these conditions are endemic. Six billion people lack access to safe, timely and affordable cardiac surgical care, whereby over 100 countries and territories lack a single cardiac surgeon. Moreover, while clinically unique, the surgical consequences of neglected cardiovascular diseases with viral origins have been poorly described in the current literature. This review provides an overview of the global burden of viral cardiovascular disease, describes access to cardiac surgical care in regions where these conditions are endemic, and further highlights surgical consequences and considerations to manage patients requiring cardiac surgical care.

BACKGROUND AND OBJECTIVE: The optimal patent ductus arteriosus (PDA) closure method in very low birth weight (VLBW) infants is uncertain. In 2019, the first transcatheter occlusion device was approved in the United States for infants ≥700 g. We described survival and short-term outcomes among VLBW infants who underwent transcatheter or surgical PDA closure (2018-2022). METHODS: Vermont Oxford Network members submitted data on infants born from 401 to 1500 g or 22 to 29 weeks' gestational age. Adjusted risk ratios (aRR) for survival, length of stay (LOS), prematurity complications, and discharge support were used to compare transcatheter versus surgical closure. Subgroup analyses were conducted for infants with birth weight ≥700 g and born in 2020-2022. RESULTS: Overall, 6410 of 216 267 infants at 726 hospitals received invasive PDA treatment. Transcatheter closure increased from 29.8% in 2018 to 71.7% in 2022. VLBW infants undergoing transcatheter closure had higher survival (adjusted rate ratio [aRR] 1.03; 1.02-1.04) with similar LOS (aRR 1.00; 0.97-1.03), neonatal complications (aRR 1.00; 0.98-1.01), and receipt of discharge support (aRR 0.94; 0.89-1.01). In subgroup analyses, survival (aRR 1.02; 1.00-1.04) and discharge support (aRR 0.90; 0.81-1.01) were similar between groups, whereas selected neonatal complications (aRR 0.95; 0.93-0.98) and LOS (aRR 0.95; 0.90-0.99) were lower after transcatheter closure. CONCLUSIONS: Transcatheter PDA closure in VLBW infants was increasingly used after 2018. Selected short-term outcomes for infants receiving transcatheter closure may be more favorable, compared with surgical, and warrants further clinical investigation.

OBJECTIVES: In patients with borderline left hearts or a severe left ventricular outflow tract obstruction, hybrid palliation can be used to stabilize the patient and postpone biventricular repair (BVR). In this study, we analysed growth of left-sided structures and outcomes of these patients. METHODS: We conducted a retrospective cohort study including patients who received hybrid palliation between January 2010 and September 2023. Echo measurements were collected at hybrid palliation, BVR and last follow-up. Growth of left ventricular structures were analysed. RESULTS: In 38 patients, hybrid palliation was used to promote growth of left ventricular structures. In total, 15 patients received a Ross-Konno/Yasui procedure, while 23 patients received conventional BVR. In patients with a conventional BVR, a significant increase was found in left ventricular volume indexed by body surface area, Z-score of aortic valve and left ventricular outflow tract between hybrid palliation and BVR. Mitral valve Z-score did not increase significantly. After BVR until follow-up, only increase of the aortic valve Z-scores and left ventricular volume indexed by body surface area was found significant. Of all included patients (n = 38), additional surgical procedures were necessary in 8 patients during the interstage period and 15 patients after BVR. Additional catheter interventions were needed in 14 patients in the interstage period and 15 after BVR. Six patients died, with no mortality in the conventional BVR group. CONCLUSIONS: Hybrid palliation as part of a staged BVR is a safe and effective initial step and promotes the growth of left ventricular structures in patients with small left-sided heart structures. Close follow-up is mandatory because extra catheter or surgical interventions are frequently needed.

OBJECTIVE: To analyze bone tissue damage at different stages of disease (El Oakley classification), treatment options for each clinical situation and results after each approach. MATERIAL AND METHODS: There were 45 patients with wound complications after cardiac surgery between October 2022 and September 2023. Thirty-eight (84.4%) patients underwent CABG, 7 (15.6%) patients - heart valve or aortic surgery. Mean age of patients was 68.1±10.3 years. There were 35 men (77.8%) and 10 women (22.2%). The first type was found in 11 (24.5%) patients, type 2-3 - 19 (42.2%), type 4 - 4 (8.8%), type 5 - 11 (24.5%) patients. RESULTS: Systemic inflammatory response syndrome was observed in 7 (36.8%) persons of the 1st group, 14 (73.7%) ones of the 2nd group, 4 (100%) patients of the 3rd group and 2 (18.2%) patients of the 4th group. C-reactive protein and procalcitonin increased in all patients with the highest values in groups 2 and 3. Redo soft tissue inflammation occurred in all groups after treatment. Mean incidence was 25%. Two (10.5%) patients died in the 2nd group and 1 (25%) patient in the 3rd group. CONCLUSION: The modern classification of sternomediastinitis does not fully characterize severity of disease in a particular patient. Simultaneous debridement with wound closure demonstrates acceptable mortality (within 10%). The highest mortality rate was observed in patients with diffuse lesions of the sternum. Less aggressive treatment approaches are possible for stable anterior chest wall.

We reported our long-term results of valve sparing aortic root replacement (VSRR) and aortic cusp repair for aortic regurgitation( AR) were satisfactory. Three hundred twenty-seven patients had VSRR, and 164 patients of them had aortic cusp repair for prolapse. At 10 years after the operation, the overall survival was 91.5%, the freedom from more than mild recurrent AR was 71.2%, and the freedom from aortic valve reoperation was 82.0%. As for the aortic cusp repair technique, there was no significant difference in the mid-term results of the recurrent AR and reoperation for the aortic valve between the central plication technique and the resuspension technique (two layers of continuous mattress sutures placed the entire length of the free margin of the aortic cusp). The resuspension technique might be useful for repairing the aortic cusp with prolapse. Furthermore, among the patients with acute aortic dissection, connective tissue disease, or aortitis, the long-term results of VSRR and aortic cusp repair were also satisfactory.

OBJECTIVES: To evaluate the impact of previous cardiac surgery (PCS) on clinical outcomes after reoperative extended arch repair for acute type A aortic dissection. METHODS: This study included 37 acute type A aortic dissection patients with PCS (PCS group) and 992 without PCS (no-PCS group). Propensity score-matching yielded a subgroup of 36 pairs (1:1). In-hospital outcomes and mid-term survival were compared between the 2 groups. RESULTS: The PCS group was older (56.7 ± 14.2 vs 52.2 ± 12.6 years, P = 0.036) and underwent a longer cardiopulmonary bypass (median, 212 vs 183 min, P < 0.001) compared with the no-PCS group. Operative death occurred in 88 (8.6%) patients, exhibiting no significant difference between groups (13.5% vs 8.4%, P = 0.237). Major postoperative morbidity was observed in 431 (41.9%) patients, also showing no difference between groups (45.9% vs 41.7%, P = 0.615). Moreover, the multivariable logistic regression analysis revealed that PCS was not significantly associated with operative mortality (adjusted odds ratio 2.58, 95% confidence interval 0.91-7.29, P = 0.075) or major morbidity (adjusted odds ratio 1.92, 95% confidence interval 0.88-4.18, P = 0.101). The 3-year cumulative survival rates were 71.1% for the PCS group and 83.9% for the no-PCS group (log-rank P = 0.071). Additionally, Cox regression indicated that PCS was not significantly associated with midterm mortality (adjusted hazard ratio 1.40, 95% confidence interval 0.44-4.41, P = 0.566). After matching, no significant differences were found between groups in terms of operative mortality (P > 0.999), major morbidity (P > 0.999) and midterm survival (P = 0.564). CONCLUSIONS: No significant differences were found between acute type A aortic dissection patients with PCS and those without PCS regarding in-hospital outcomes and midterm survival after extended arch repair.

BACKGROUND: Evaluating outcomes of concurrent Cox-Maze procedures in elderly patients undergoing high-risk cardiac surgery. MEHODS: We retrospectively identified patients aged over 70 years with Atrial Fibrillation (AF) from 2011 to 2017 who had two or more other cardiac procedures. They were subdivided into two groups: 1. Cox-Maze IV AF ablation. 2. No-Surgical AF treatment. A propensity match score was used to generate a homogeneous cohort and to eliminate confounding variables. Heart rhythm was assessed from Holter reports or 12-lead ECG. Follow-up data was collected through telephone consultations and medical records. RESULTS: There were 239 patients. Median follow up was 61 months. 70 patients had Cox-Maze IV procedures (29.3%). Demographic, intra- and post-operative outcomes were similar between groups although duration of pre-operative AF was shorter in Cox-Maze group (p = 0.001). There was no significant 30-day mortality difference in propensity matched cohorts (n = 84. P = 0.078). Sinus rhythm at annual and latest follow-up was 84.9% and 80.0% respectively in Maze group - 160 patients (66.9%) were alive at long-term follow-up with good survival outcomes in Cox Maze group. There was a high proportion of patients in NYHA 1 status in Cox-Maze group. No differences observed in freedom from stroke (p = 0.80) or permanent pacemaker (p = 0.33) between the groups. CONCLUSIONS: Surgical ablation is beneficial in elderly patients undergoing high-risk surgery - promoting excellent long-term freedom from AF and symptomatic / prognostic benefits, without added risk. Therefore, surgical risk should not be reason to deny benefits of concomitant AF-ablation. CLINICAL TRIAL REGISTRATION: Not required.
