Objective: Reverse hybrid coronary revascularization (RHCR) is the integration of percutaneous coronary intervention (PCI) followed by sternal-sparing coronary artery bypass grafting in patients with multivessel coronary artery disease (CAD). We sought to review our RHCR experience over a 10-year period using PCI first followed by robotic totally endoscopic coronary artery bypass (TECAB). Methods: We reviewed the indications and outcomes in patients who underwent RHCR (PCI with drug-eluting stents first, followed by TECAB). Results: From July 2013 to August 2024, 882 robotic TECAB procedures were performed at our institution. Of these, 60 patients underwent RHCR. The mean age of the patients was 66.7 ± 10 years, and 74% were male patients. The target vessel stented was the right coronary artery in 52 patients (87%), circumflex coronary artery in 10 patients (17%), and diagonal in 4 patients (7%). The average time from PCI to TECAB was 3.8 ± 1.64 months. A total of 35 patients (58%) underwent multivessel grafting, with 74% bilateral internal thoracic artery (ITA) use. The mean operative time was 253 ± 88 min, and the mean hospital length of stay was 2 ± 0.76 days. There were no conversions, perioperative strokes, or myocardial infarctions. At mean follow-up of 34 ± 27 months, cardiac-related mortality occurred in 1 patient. Freedom from major adverse cardiac or cerebrovascular events including repeat revascularization was 93%. Conclusions: RHCR is safe and feasible in selected patients with multivessel CAD. In experienced hands, stenting first followed by robotic TECAB with left ITA or bilateral ITA grafts resulted in excellent early and midterm outcomes. Further studies are warranted.

Objective: This study aims to identify the perceived barriers and factors contributing to the slow adoption of robotic technology among coronary surgeons. Methods: We administered an anonymous online survey during the 2023 Society for Thoracic Surgeons (STS) Coronary Conference and included questions about factors associated with the lack of, or slow adoption of, robotics in coronary artery bypass surgery. Results: A total of 75 coronary surgeons completed the anonymous online survey. Of these respondents, 30 surgeons (39.4%) reported having more than 15 years of experience as independent coronary surgeons. Among the 71 surgeons (95%) who were not using robotic technology, the barriers to adoption (from most important to less important) were lack of skill or experience with robotic technology (mean score, 2.56 ± 1.84), followed by the lack of referral of patients with hybrid or single-vessel disease from cardiologists (2.81 ± 1.76), the need for more support and learning opportunities (e.g., hands-on courses, online courses; 3.44 ± 1.98), and more data to support the efficacy and safety of robotic coronary surgery (3.63 ± 2.22). Moreover, 38 surgeons (50%) expressed a willingness to consider robotic coronary surgery if industry provided appropriate devices such as stabilizers and automated anastomotic devices. Finally, 53 surgeons (69.7%) reported being unaware of the Thoracic Surgery Foundation and STS Advanced Robotic Cardiac Surgery Fellowship award with a coronary track. Conclusions: The findings from this survey identify the barriers to adopting robotic technology in coronary surgery. Addressing these barriers through targeted interventions could foster wider acceptance and use of robotic technology in coronary bypass surgery.

Objective: Femoral artery cannulation is the most commonly used approach for cardiopulmonary bypass (CPB) in robotic cardiac procedures. However, without adding a distal perfusion cannula, leg ischemia can occur in up to 11.5% of patients. There is a well-described 2 to 4 mm size arterial branch that originates from the medial side of the external iliac artery or inferior epigastric artery, immediately above the inguinal ligament, and connects to the obturator artery. Therefore, it was historically named the corona mortis , which means “crown of death” in Latin. When peripheral cannulation is performed above this branch in the external iliac artery, we consider it a corona “vitae” because of its role as a limb-saving collateral. We report herein our standard technique of peripheral cannulation without the need of a distal perfusion cannula and preventing limb ischemia. Methods: We included all patients who underwent robotic cardiac surgery with peripheral cannulation over a 16-month period at our institution. We cannulated just above the level of the inguinal ligament through a 2 to 3 cm transverse skin incision. The incidence of limb ischemia and vascular complications was recorded and analyzed. Results: During the study period, 133 patients underwent robotic cardiac procedures with peripheral “external iliac” CPB. The size of the cannula was 21F or larger in 73% and 23F in 54% of the patients. No leg ischemia or femoral artery complications requiring additional intervention occurred. Conclusions: External iliac cannulation can be successfully performed in robot-assisted cardiac surgery using relatively large cannulas without the need of a distal limb perfusion catheter, with good results. In our view, given the importance of the corona mortis (“crown of death” in Latin) in perfusing the limb during CPB, we propose a new name for this artery in robotic cardiac surgery, namely, the corona vitae (“crown of life” in Latin).

Objective: Robotic totally endoscopic coronary artery bypass (TECAB) grafting is the least invasive form of coronary bypass surgery. However, despite its advantages, this approach has not gained widespread adoption. One possible reason is the advanced and complex robotic skills required to execute a totally endoscopic sutured coronary anastomosis. We prepared a novel, inexpensive, easy to set up robotic TECAB simulator. Methods: A pig heart was placed in a cardboard box, and 3 holes were made on the side to mimic the exposure and surgical ergonomics of TECAB port placement. Four robotic ports were placed and docked to the da Vinci Si robot (Intuitive Surgical, Sunnyvale, CA, USA). Monofilament 7:0 suture (7 cm long) was used to perform the anastomosis to the left anterior descending artery using remnant conduit. Seven cardiac surgeons of various training levels participated and were asked to fill out a 10-point questionnaire. Results: The cost of the simulator totaled $20 per session, with 20 min to assemble. Each session allowed each trainee to practice 3 to 4 coronary anastomoses. Three cardiac surgeons completed the survey and strongly agreed that the model was easy to set up, the anastomotic exercise was realistic, and that this practice helped them gain confidence. Conclusions: Our TECAB simulator is inexpensive, easy to set up, and allows trainees to practice endoscopic coronary suturing. We believe this to be a valuable training tool to learn how to do TECAB for established surgeons and that such a simulator may be of great value to cardiothoracic training programs and their trainees. Further studies are warranted.

Background In this study, we aimed to evaluate the educational value and students’ satisfaction with the hand-made low-cost cricothyrotomy simulation model. Materials and Methods A low-cost and hand-made model and a high-fidelity model were used to assess the students. The students’ knowledge and satisfaction were evaluated using a 10-item checklist and a satisfaction questionnaire, respectively. Medical interns in the present study participated in a two-hour briefing and debriefing session held in the Clinical Skills Training Center by an emergency attending doctor. Results Based on the results of data analysis, no significant differences were found between the two groups in terms of gender, age, the month of internship, and last semester’s grade ( P = .628, .356, .847, and .421, respectively). We also found no significant differences between our groups in terms of the median score of each item in the assessment checklist ( P = .838, .736, .805, .172, .439, .823, .243, .950, .812, and .756, respectively). The study groups had no significant difference in the median total scores of the checklist as well ( P = .504). Regarding the students’ satisfaction, our results showed that interns evaluated their experience of the model as positive (median scores of 4 and 5 out of 5). They also gave the hand-made model a median score of 7 in comparison with the high-fidelity model and 8 out of 10 for its usability. Conclusion The study results showed that a low-cost model could be as effective as an expensive high-fidelity model for teaching the necessary knowledge of cricothyrotomy techniques to medical trainees.

Abstract This case presentation involves a 57-year-old-male who suffered multiple adverse sequels from the delayed diagnosis of a large presacral mass. He initially presented with lower extremity deep vein thrombosis (DVT). Several months later, he had developed a pulmonary embolus. Imaging demonstrated a 13 × 14 cm presacral pelvic mass that occluded the right-sided venous return from the leg and caused the DVT and pulmonary embolism. An inferior vena cava filter was placed and eventually clotted. He then was referred to our institution for surgical consultation. The patient received lytic therapy and unfortunately developed hematemesis and a significant hemoglobin drop. An esophagogastroduodenoscopy (EGD) showed a black esophagus. A transthoracic echocardiogram showed a patent foramen ovale. The patient eventually stabilized and a repeat EGD a week later showed resolution of the ischemic esophagus. The patient later underwent a resection of the pelvic mass. The surgical approach and the surgical decision-making will be discussed.

Abstract Purpose: Data on laparoscopic totally extraperitoneal inguinal hernia repairs (TEP-IHRs) suggest that approximately 250 operations are needed to gain mastery, but the annual volume required to maintain high-quality outcomes is unknown. Materials and Methods: A retrospective review was performed of every patient undergoing a TEP-IHR at the Mayo Clinic (Rochester, MN) from 1995 to 2011. Analysis focused on the annual volume of 21 staff surgeons and their specific patient outcomes broken up into three groups: Group 1 (G1) ( n = 1 surgeon) performed >30 repairs per year; Group 2 (G2) ( n = 3 surgeons), 15–30 repairs; and Group 3 (G3) ( n = 17), <15 repairs. Results: In total, 1601 patients underwent 2410 TEP-IHRs, with no significant patient demographic differences among groups. Greater annual surgeon volume (G1 > G2 > G3) was associated with improved outcomes as shown by the respective rates for intra- (1%, 2.6%, and 5.6%) and postoperative (13%, 27%, and 36%) complications, need for overnight stay (17%, 23%, and 29%), and hernia recurrence (1%, 4%, and 4.3%) (all P < .05). Surgeons with greater annual operative volumes were more likely to operate on patients with bilateral and recurrent hernias. Surgeons performing at least 15 repairs per year (G1 and G2) showed improvements in quality metrics over time. Conclusions: Annual operative volumes of >30 repairs per year are associated with the highest quality outcomes for TEP-IHR. Operative volumes of at least 15 repairs per year are associated with improvements in quality metrics over time. Mentorship and operative assistance of low-volume TEP-IHR surgeons may be useful in improving patient outcomes.
