Differential hypoxemia during peripheral cardiopulmonary bypass.

Minimally invasive cardiac surgery (MICS) for mitral valve repair often uses cardiopulmonary bypass (CPB) through peripheral femoro-femoral cannulation. A rare complication of differential hypoxemia can cause upper body hypoxia. A 38-year-old man with Barlow Syndrome underwent MICS mitral valve repair with peripheral CPB. During the procedure, his right upper limb SpO2 dropped to 65% due to dislodgement of the venous cannula from the superior vena cava (SVC), causing inadequate right heart venous drainage, leading to differential hypoxemia. Repositioning the venous cannula to the SVC restored SpO2 to 100%, allowing the surgery to proceed without complications. Differential hypoxemia happens when deoxygenated blood from the left ventricle mixes with oxygenated CPB blood. A literature review found only one previous case of this complication on peripheral CPB for MICS. Unlike our case, Kanda et al. monitored cerebral hypoxia, underscoring the importance of cerebral oxygenation monitoring in future MICS procedures due to higher stroke risk compared to conventional sternotomy. We recommend cerebral oxygenation monitoring in future MICS to prevent neurological complications, and highlight the need for effective team communication in the cardiac operating theatre.

Efficacy of epidural anesthesia in minimally invasive cardiac surgery

Introduction: The most commonly performed minimally invasive cardiac surgery (MICS) is lateral minithoracotomy, which requires one of the most painful incisions. Adequate postoperative pain management is essential for cardiac surgery to prevent perioperative complications. Thoracic epidural analgesia (TEA) is the gold standard for thoracotomy; however, it is still controversial because of the risk of epidural hematoma following systematic heparinization. The objective of our study was to investigate the safety and efficacy of TEA following MICS. Methods: The clinical data of patients aged over 18 years who underwent elective MICS and received epidural analgesia along with general anesthesia between January 2014 and March 2019 were reviewed. Data were collected, including patient demographics, operative data, postoperative pain, postoperative course, and complications. Chronic pain was evaluated 6 months after discharge, and we defined it as a NRS score ≧3. Postoperative complications included epidural-related complications. Results: Seventy patients were included in the analysis. The mean NRS score was below 2. We collected chronic pain data from 52 patients and found that 11 patients had chronic pain. TEA-related complications were not observed. Conclusion: The current observational study revealed that TEA following lateral thoracotomy was effective for acute pain as well as chronic pain without causing any severe epidural-related complications. Protocols to prevent potential devastating complications, including epidural hematoma, should follow the American Society of Regional Anesthesia and Pain Medicine recommendation. If the rules are strictly followed, TEA can be a safe and effective pain management method for patients who undergo MICS.

Ultra-fast-track cardiac anesthesia in minimally invasive cardiac surgery: a retrospective observational study.

There is no uniformity on the safety profile of ultra-fast-track cardiac anesthesia (UFTCA), and there is a lack of research on the postoperative lung function status of patients with UFTCA. This retrospective study was to examine the benefits of UFTCA on the postoperative recovery and pulmonary function of patients undergoing minimally invasive cardiac surgery (MICS). This retrospective study was performed on patients who underwent MICS at Zhejiang Provincial People's Hospital between January 2022 and July 2023. Patients were retrospectively segregated into two groups: UFTCA group and conventional general anesthesia (CGA group). Primary endpoints encompassed differences in the duration of postoperative intensive care unit (ICU) stay and overall hospital stay. Secondary observations included in-hospital mortality rate, 3-month post-discharge survival rate, oxygenation indexes of preoperative (T0), immediately after extubation (T1), 6 hours after extubation (T2), and 12 hours after extubation (T3), use of high-flow nasal cannula oxygen therapy in the ICU, postoperative total chest drainage volume, and the rate of complications. Group comparisons were performed using grouped t-tests and repeated measures analysis of variance (ANOVA). The UFTCA group (n=327) demonstrated shorter ICU and hospital stays when compared with the CGA group (n=216) (P=0.001). At the immediately after extubation, the UFTCA group exhibited a decrease in oxygenation index [arterial oxygen partial pressure (PaO2)/fraction of inspired oxygen (FiO2)] accompanied by elevated alveolar-arterial oxygen tension difference [P(A-a)O2] and respiratory index [P(A-a)O2/PaO2] values compared to the CGA group (P=0.001). However, by 12 hours after extubation, the UFTCA group manifested an improved PaO2/FiO2 and diminished P(A-a)O2/PaO2 values compared to the CGA group. The UFTCA group required high-flow oxygen therapy after extubation with greater frequency than the CGA group (P=0.001). However, neither the UFTCA nor CGA group had patients who needed reintubation (P>0.05). No significant differences were observed in postoperative atelectasis and pulmonary edema rates between the groups (P>0.05), the UFTCA group recorded a diminished total chest drainage volume postoperatively (P=0.001). Incidence of postoperative nausea and vomiting (PONV) was heightened in the UFTCA group (P=0.01), while the incidence of delirium was less frequent when compared with the CGA group (P=0.001). UFTCA demonstrates potential benefits in minimizing ICU and postoperative hospital stay in patients undergoing MICS. This approach also contributes to a reduction in postoperative chest drainage volume and a decreased likelihood of postoperative delirium. Despite the initial decline in lung oxygenation immediately following early post-extubation, subsequent lung function proves to be superior, with no differences in postoperative atelectasis or pulmonary edema rates. However, the implementation of UFTCA requires additional strategies to prevent the occurrence of PONV.

Periareolar Incision for Endoscopic Cardiac Surgery: How to Do It?

Minimally invasive cardiac surgery (MICS) has demonstrated its efficacy in diminishing postoperative pain, accelerating early recovery, and facilitating a prompt return to daily activities. Notably, the periareolar incision has gained prominence owing to its superior cosmesis. This article elucidates the procedural details for implementing periareolar incision access in MICS and providing insights into its technique and applications.

Effect of minimally invasive cardiac surgery on hospital length of stay: A systematic review and meta-analysis

Background: Perioperative management using minimally invasive cardiac surgery (MICS), compared to full sternotomy (FS) cardiac surgery, is considered to improve postoperative recovery, and reduce hospital length of stay (LOS). Methods: A comprehensive systematic search was conducted across MEDLINE/PubMed, Embase, and the Cochrane library to identify RCT comparing MICS to FS approach for aortic valve, mitral valve, and coronary artery bypass surgery. Meta-analysis of extracted data was performed using random effects models. Results: A total of 33 RCTs including 2920 patients were identified. Overall MD (95% CI) for hospital and intensive care unit (ICU) LOS after MICS was significantly shorter compared to FS (-0.88 days (-1.55;-0.20), p<0.013; 2606 patients) and (-0.23 days (-0.41;-0.05), p=0.012; 2242 patients), respectively. Additionally, postoperative blood loss was reduced with the use of MICS, (-192.07 ml (-292.32;-91.82), p=0.002; 718 patients). There was no evidence for differences between both groups in terms of postoperative ventilation times, duration of surgery, reintervention rate, incidence of postoperative atrial fibrillation or stroke, hospital mortality, or 1-year mortality. Conclusion: Within the limitations of a meta-analysis, MICS was found to be effective in promoting faster recovery by reducing postoperative blood loss, ICU, and hospital LOS.

Maximizing Minimally Invasive Cardiac Surgery With Enhanced Recovery (ERAS).

We convened a group of cardiac surgeons, intensivists, and anesthesiologists with extensive experience in minimally invasive cardiac surgery (MICS) and perioperative care to identify the essential elements of a MICS program and the relationship with Enhanced Recovery After Surgery (ERAS). The MICS incision should minimize tissue invasion without compromising surgical goals. MICS also requires safe management of hemodynamics and preservation of cardiac function, which we have termed myocardial management. Finally, comprehensive perioperative care through an ERAS program should be provided to allow patients to achieve optimal recovery. Therefore, we propose that MICS requires 3 elements: (1) a less invasive surgical incision (non-full sternotomy), (2) optimized myocardial management, and (3) ERAS. We contend that the full benefit of MICS can be achieved only by also utilizing an ERAS platform.

Feasibility of deescalating postoperative care in enhanced recovery after cardiac surgery.

Enhanced Recovery After Surgery (ERAS) prioritizes faster functional recovery after major surgery. An important aspect of postoperative ERAS is decreasing morbidity and immobility, which can result from prolonged critical care. Using current clinical data, our aim was to analyze whether a six-hour monitoring period after Minimally Invasive Cardiac Surgery (MICS) might be sufficient to recognize major postoperative complications in a future Fast Track pathway. Additionally, we sought to investigate whether it could be possible to deescalate the setting of postoperative monitoring. 358 patients received MICS and were deemed suitable for an ERAS protocol between 01/2021 and 03/2023 at our institution. Of these, 297 patients could be successfully extubated on-table, were transferred to IMC or ICU in stable condition and therefore served as study cohort. Outcomes of interest were incidence and timing of Major Adverse Cardiac Events (MACE; death, myocardial infarction requiring revascularization, stroke), bleeding requiring reexploration and Fast Track-associated complications (reintubation and readmission to ICU). Patients' median age was 63 years (IQR 55-70) and 65% were male. 189 (64%) patients received anterolateral mini-thoracotomy, primarily for mitral and/or tricuspid valve surgery (n = 177). 108 (36%) patients had partial upper sternotomy, primarily for aortic valve repair/replacement (n = 79) and aortic surgery (n = 17). 90% of patients were normotensive without need for vasopressors within 6 h postoperatively, 82% of patients were transferred to the general ward on postoperative day 1 (POD). Two (0.7%) MACE events occurred, as well as 4 (1.3%) postoperative bleeding events requiring reexploration. Of these complications, only one event occurred before transfer to the ward - all others took place on or after POD 1. There was one instance of reintubation and two of readmission to ICU. If MICS patients can be successfully extubated on-table and are hemodynamically stable, major postoperative complications were rare in our single-center experience and primarily occurred after transfer to the ward. Therefore, in well selected MICS patients with uncomplicated intraoperative course, monitoring for six hours, possibly outside of an ICU, followed by transfer to the ward appears to be a feasible theoretical concept without negative impact on patient safety.

Efficacy and Outcomes of Para-Annular Plication in Mitral Valve Repair via Right Mini-Thoracotomy.

We aim to assess the efficacy and safety of left atrial plication (LAP), particularly para-annular plication, using a right mini-thoracotomy approach. Among 90 mitral valve repair (MVr) procedures performed at our institution between 2016 and 2023, 16 left atrial plication cases for left atrial enlargement (diameter: >50 mm) were assessed; nine cases underwent median sternotomy (conventional) (Group C), and seven cases underwent minimally invasive cardiac surgery (MICS) (Group M). The surgical protocol involved mitral valve repair via a right-sided left atrial approach, incorporating para-annular plication to suture the posterior wall. The mean follow-up duration was 3.3±2.4 years. Mortality within 30 days of surgery or during hospitalization did not occur. Postoperative complications included one case in each group that required reoperation for hemorrhage originating extraneously in the left atrium. Postoperative echocardiographic assessments revealed a comparable reduction in left atrial diameter (C/M: 80.3±7.0/80.7±14.6%; p=0.94), left atrial volume index (55.6±19.3/68.3±34.1%; p=0.36), and aorto-mitral angle (AMA) enlargement (113.8±7.3/107.5±12.2%; p=0.22). The three-year survival rate (88.9%/75.0%; p=0.33) was comparable between groups. The synergistic utilization of left atrial plication with para-annular plication via right mini-thoracotomy can enhance the postoperative outcomes of mitral valve repair.

Minimally invasive cardiac surgeries in 2021: annual report by Japanese society of minimally invasive cardiac surgery.

Although minimally invasive cardiac surgery (MICS) procedures are widely performed throughout Japan, nationwide data regarding treated cases are limited. Up-to-date results for cardiovascular surgery are vital for quality control in clinical practice. Presented here is the 2021 annual report based on data from the Japan Cardiovascular Surgery Database (JCVSD). Records noted in the JCVSD of patients who underwent mitral valve surgery, aortic valve replacement (AVR), coronary artery bypass grafting (CABG), atrial septum defect (ASD) closure, or cardiac tumor resection via right or left minithoracotomy, as well as thoracoscopic- or port-assisted, or robotic-assisted approaches, in 2021 were examined. Perioperative parameters including mortality and morbidity was evaluated. The 30-day and in-hospital mortalities for isolated mitral valve repair (n = 1211) were 0.1% and 0.2%, respectively, while those for all mitral valve repair (n = 2017) were 0.05% and 0.2%, respectively. More than 100 facilities were found to perform fewer than five MICS mitral valve surgery cases per year. As for MICS-AVR, 30-day and in-hospital mortalities for isolated AVR (n = 818) were 0.5% and 0.5%, respectively, while those for all AVR (n = 987) were 0.6% and 1.1%, respectively. Additionally, those for MICS-CABG (n = 400) were 0.8% and 0.5%, respectively. Those for ASD (n = 183) and cardiac tumor (n = 96), were 0.5% and 0.5%, respectively, and 0% and 1.0%, respectively. This is the first report of MICS results of procedures performed in Japan based on the 2021 JCVSD data. Additional results obtained with a similar data collection method are expected and details on MICS are being collected starting 2024.

Anesthesia for Minimal Invasive Cardiac Surgery: The Bonn Heart Center Protocol.

The development and adoption of minimally invasive techniques has revolutionized various surgical disciplines and has also been introduced into cardiac surgery, offering patients less invasive options with reduced trauma and faster recovery time compared to traditional open-heart procedures with sternotomy. This article provides a comprehensive overview of the anesthesiologic management for minimally invasive cardiac surgery (MICS), focusing on preoperative assessment, intraoperative anesthesia techniques, and postoperative care protocols. Anesthesia induction and airway management strategies are tailored to each patient's needs, with meticulous attention to maintaining hemodynamic stability and ensuring adequate ventilation. Intraoperative monitoring, including transesophageal echocardiography (TEE), processed EEG monitoring, and near-infrared spectroscopy (NIRS), facilitates real-time assessment of cardiac and cerebral perfusion, as well as function, optimizing patient safety and improving outcomes. The peripheral cannulation techniques for cardiopulmonary bypass (CPB) initiation are described, highlighting the importance of cannula placement to minimize tissue as well as vessel trauma and optimize perfusion. This article also discusses specific MICS procedures, detailing anesthetic considerations and surgical techniques. The perioperative care of patients undergoing MICS requires a multidisciplinary approach including surgeons, perfusionists, and anesthesiologists adhering to standardized treatment protocols and pathways. By leveraging advanced monitoring techniques and tailored anesthetic protocols, clinicians can optimize patient outcomes and promote early extubation and enhanced recovery.

Different approach, similar outcomes: the impact of surgical access routes in minimally invasive cardiac surgery on enhanced recovery after surgery.

Enhanced recovery after surgery (ERAS) is a growing phenomenon in all surgical disciplines and aims to achieve a faster functional recovery after major operations. Minimally invasive cardiac surgery (MICS) therefore integrates well into core ERAS values. Surgical access routes in MICS include right anterolateral mini-thoracotomy (MT) as well as partial upper mini-sternotomy (PS). We seek to compare outcomes in these two cohorts, both of which were enrolled in an ERAS scheme. 358 consecutive patients underwent MICS and perioperative ERAS at our institution between 01/2021 and 03/2023. Patients age >80 years, with BMI > 35 kg/m², LVEF ≤ 35%, endocarditis or stroke with residuum were excluded. Retrospective cohort analysis and statistical testing was performed on the remaining 291 patients. The primary endpoint was successful ERAS, secondary endpoints were the occurrence of major bleeding, ERAS-associated complications (reintubation, return to ICU) as well as access-related complications (wound infection, pleural and pericardial effusions). 170 (59%) patients received MT for mitral and/or tricuspid valve surgery (n = 162), closure of atrial septal defect (n = 4) or resection of left atrial tumor (n = 4). The remaining 121 (41%) patients had PS for aortic valve repair/replacement (n = 83) or aortic root/ascending surgery (n = 22) or both (n = 16). MT patients' median age was 63 years (IQR 56-71) and 65% were male, PS patients' median age was 63 years (IQR 51-69) and 74% were male. 251 (MT 88%, PS 83%, p = 0.73) patients passed through the ERAS program successfully. There were three instances of reintubation (2 MT, 1 PS), and three instances of readmission to ICU (2 MT, 1 PS). Bleeding requiring reexploration occurred six times (3 MT, 3 PS). There was one death (PS), one stroke (MT), and one myocardial infarction requiring revascularization (MT). There were no significant differences in any of the post-operative outcomes recorded, except for the incidence of pericardial effusions (MT 0%, PS 3%, p = 0.03). Despite different surgical access routes and underlying pathologies, results in both the MT and the PS cohort were generally comparable for the recorded outcomes. ERAS remains safe and feasible in these patient groups.

The Impact of Preoperative Combined Pectoserratus and/or Interpectoral Plane (Pectoralis Type II) Blocks on Opioid Consumption, Pain, and Overall Benefit of Analgesia in Patients Undergoing Minimally Invasive Cardiac Surgery: A Prospective, Randomized, Controlled, and Triple-blinded Trial

ObjectiveAcute postoperative pain remains a major obstacle in minimally invasive cardiac surgery (MICS). Evidence of the analgesic benefit of chest wall blocks is limited. This study aimed to assess the influence of combined pectoserratus-plane-block plus interpectoral-plane-block (PSPB+IPPB) on postoperative pain and overall benefit of analgesia compared to placebo. DesignProspective, randomized, triple-blinded. SettingThe operating room, intensive care unit of a university hospital Participants60 patients undergoing elective right-lateral MICS. InterventionsPatients were randomly assigned to preoperative PSPB+IPPB with 30 ml ropivacaine 0.5% or saline. Measurements and Main resultsThe primary endpoint was total intravenous morphine milligram equivalents administered in the first 24 hours after extubation (24 h - ivMME). Secondary endpoints included the Overall Benefit of Analgesia Score (OBAS) at 24h after extubation and repeated visual analogue scale (VAS). 24 hours - ivMMEs were significantly lower (median (IQR): 4.2 mg (2.1 – 7.9) versus 8.3 mg (4.2 - 15.7); p = 0.025; mean difference: 6.7 mg (0.94-12 mg), p = 0.024; Cohen's d: 0.64 (0.09-1.2)). Moreover, OBAS at 24 hours and VAS after extubation were significantly lower (4.0 (3.0 – 6.0) versus 7.0 (3.0 – 9.0), p = 0.043; 0.0 cm (0.0 - 2.0) versus 1.5 cm (0.3 - 3.0); p = 0.030). VAS did not differ between groups at later points. ConclusionsPre-operative PSPB+IPPB reduced 24 hours post-extubation opioid consumption, pain at extubation and OBAS. Given its low risk and expedient placement, it could be a helpful addition to MICS protocols. Future studies should evaluate these findings in multicenter settings, and further elucidate the optimal timing of block placement.

A comparative analysis of open heart surgery and minimally invasive cardiac surgery in exercise-based cardiac rehabilitation

BackgroundHistorically, the majority of patients admitted to inpatient exercise-based cardiac rehabilitation (EBCR) have undergone open heart surgery (OHS). However, with advances in minimally invasive cardiac surgery (MICS), these patient groups are also increasingly referred for inpatient EBCR. Herein, we aimed to compare the progress of these groups during rehabilitation.MethodsIn this prospective, nonrandomized study, 403 inpatient EBCR patients were recruited from December 2022 until September 2023 and stratified into two groups: OHS, and MICS. Participants completed a 3-4-week certified EBCR program. The primary endpoint was defined as a change in the 6-minute walk test (6MWT). Moreover, a comprehensive panel of quality-of-life (QoL) assessments were performed at admission and discharge.ResultsAt baseline, patients with OHS were older (66 years [IQR 59 – 72]), more often male (83%), and underwent emergency/urgent procedures more often (20%) than patients with MICS. Furthermore, patients with MICS showed a better 6MWT at admission (426 meters [IQR 336 – 483]) compared to patients with OHS (381 meters [IQR 299 – 453]). While all patients were able to increase the distance in the 6MWT, regression analyses in fully adjusted models showed no difference in improvements between the two groups (β -5, 95% CI, -26 – 14, p = 0.58). Moreover, during EBCR, we observed significant improvements in all QoL measures in all groups.ConclusionsIn this study, improvements in fitness, as assessed by the 6WMT were observed in all groups. Furthermore, multiple QoL measures improved equally across all groups. These encouraging results emphasize the importance of EBCR.

Feasibility of on-table extubation after minimally invasive cardiac surgeries: A case series

Minimally Invasive Cardiac Surgery (MICS), which involves less invasive approaches using smaller incisions, has various advantages. MICS had an even better outcome with on-table extubation, including early postoperative recovery and reduced postoperative complications. The objective of our case series was to demonstrate early postoperative recovery and reduced postoperative complications after on-table extubation of MICS cases. In our case series, we have analyzed 5 MICS cases, where the anaesthesia technique was tailored to extubate the patient on the table and followed up till discharge. All 5 patients were extubated on the table safely. One patient had transient hypercapnia for 30 minutes post-extubation. There were no other postoperative complications. The inotropic support, length of stay in the Intensive Care Unit (ICU) and the hospital were reduced. : It is feasible and safe to extubate MICS cases on the table with a multidisciplinary approach that helps to reduce post-operative complications and duration of stay in the hospital.

Minimally invasive cardiac surgery in patients with heart disease: Integrative review

Objective: This review aimed to analyze and synthesize evidence regarding the efficacy and safety of minimally invasive cardiac surgery (MICS) compared to traditional surgical approaches. Methods: A search was conducted in major scientific databases, following specific inclusion and exclusion criteria, allowing for data extraction and analysis to identify patterns and trends related to MICS. Results: Findings revealed that MICS is associated with lower incidence of postoperative complications, shorter recovery time, reduced postoperative pain, and shorter hospital stay compared to traditional surgery. Moreover, MICS has shown to be safe, effective, and capable of providing satisfactory outcomes, contributing to improved surgical outcomes and quality of life for patients undergoing cardiac procedures. Conclusion: MICS is considered an effective and feasible technique with benefits such as shorter stay in the intensive care unit (ICU) and hospital, reduced surgical trauma, pain, and better postoperative recovery, thereby enhancing patient quality of life.

Multi-vessel coronary artery grafting: analyzing the minimally invasive approach and its safety.

At our institution, we perform off-pump coronary artery bypass (OPCAB) as a standard procedure. Moreover, patients with favorable coronary anatomy and condition are selected for minimally invasive cardiac surgery (MICS)-OPCAB. We retrospectively compared early outcomes, focusing on safety, between MICS-OPCAB and conventional off-pump techniques for multivessel coronary artery bypass grafting (CABG). From August 2017 to September 2022, 1,220 patients underwent multivessel coronary artery grafting at our institution. They were divided into the MICS-OPCAB group (MICS group = 163 patients) and the conventional OPCAB group (MS group = 1057 patients). Propensity score matching (1 : 1 ratio) was applied to the MICS-OPCAB and MS groups (149 patients per group) based on 23 preoperative clinical characteristics. After matching, there were no significant differences in preoperative characteristics between the groups. The MICS group had a lower total graft number (2.3 ± 0.6 vs. 2.9 ± 0.8, p < 0.001) and fewer distal anastomoses (2.7 ± 0.8 vs. 3.2 ± 0.9, p < 0.001). There were no significant differences in hospital stay, intensive care unit stay, postoperative complications, and 30-day mortality. The MICS group had less drain output (MICS 350 ml [250-500], MS 450 ml [300-550]; p = 0.013). Kaplan-Meier analysis revealed no significant differences in postoperative MACCE (major adverse cardiac or cerebrovascular events)-free and survival rates between the groups (MACCE-free rate p = 0.945, survival rate p = 0.374). With proper patient selection, MICS-OPCAB can provide good short to mid-term results, similar to those of conventional OPCAB.

Percutaneous Versus Surgical Femoral Cannulation in Minimally Invasive Cardiac Surgery: A Systematic Review and Meta-Analysis.

Minimally invasive cardiac surgery (MICS) is increasing worldwide. In most cases, the surgical technique includes cannulation of the groin for the establishment of cardiopulmonary bypass, requiring a second surgical incision (SC) for exposure and cannulation of the femoral vessels. With the introduction of arterial closure devices, percutaneous cannulation (PC) of the groin has become a possible alternative. We performed a meta-analysis and systematic review to compare clinical endpoints between the patients who underwent PC and SC for MICS. Three databases were assessed. The primary outcome was any access site complication. Secondary outcomes were perioperative mortality, any wound complication, any vascular complication, lymphatic complications, femoral/iliac stenosis, stroke, procedural duration, and hospital length of stay (LOS). A random effects model was performed. A total of 5 studies with 2,038 patients were included. When compared with PC, patients who underwent SC showed a higher incidence of any access site complication (odds ratio [OR] = 3.09, 95% confidence interval [CI]: 1.87 to 5.10, P < 0.01), any wound complication (OR = 10.10, 95% CI: 3.31 to 30.85, P < 0.01), lymphatic complication (OR = 9.37, 95% CI: 2.15 to 40.81, P < 0.01), and longer procedural duration (standardized mean difference = 0.31, 95% CI: 0.12 to 0.51, P < 0.01). There was no significant difference between the 2 groups regarding perioperative mortality, any vascular complication, femoral/iliac stenosis, stroke, or hospital LOS. The analysis suggests that surgical groin cannulation in MICS is associated with a higher incidence of any access site complication (especially wound complication and lymphatic fistula) and with a longer procedural time compared with PC. There was no difference in perioperative mortality.

Minimally Invasive Approach versus Sternotomy for Cardiac Surgery in Jehovah's Witness Patients

To evaluate the outcomes of minimally invasive cardiac surgery (MICS) compared with the sternotomy approach for Jehovah's Witness (JW) patients who cannot receive blood transfusions DESIGN: This was a retrospective observational study. The study was conducted at a specialized cardiovascular intervention and surgery institute. The study cohort comprised JW patients undergoing cardiac surgery between September 2016 and July 2022. None MEASUREMENTS AND MAIN RESULTS: Patients (n = 63) were divided into MICS (n = 19) and sternotomy (n = 44) groups, and clinical outcomes were analyzed. There was no difference in types of operation except coronary bypass grafting (n = 1 [5.3%] in the MICS group v n = 20 [45.5%] in the sternotomy group; p = 0.005). There were no between-group differences in early mortality and morbidities. Overall survival did not differ significantly during the follow-up period (mean, 43.9 ± 24.4 months). The amount of chest tube drainage was significantly lower in the MICS group on the first postoperative day (mean, 224.0 ± 122.7 mL v 334.0 ± 187.0 mL in the sternotomy group; p = 0.022). The mean hemoglobin level was significantly higher in the MICS group on the day of operation (11.7 ± 1.3 mg/dL v 10.6 ± 2.0 mg/dL in the sternotomy group; p = 0.042) and the first postoperative day (12.3 ± 1.8 mg/dL v 11.2 ± 1.9 mg/dL; p = 0.032). MICS for JW patients showed favorable early outcomes and mid-term survival compared to conventional sternotomy. MICS may be a viable option for JW patients who decline blood transfusions.
