Minimally invasive cardiac surgery off-pump coronary artery bypass (MICSOPCAB) has become increasingly prevalent, with devices like the heart positioner aiding in surgical precision. However, rare complications such as epicardial hematoma can occur. Here, we present a case of a 75-year-old man undergoing MICSOPCAB who developed an epicardial hematoma due to the heart positioner. The hematoma was successfully repaired intraoperatively with direct suturing and large felts. Postoperative recovery was uneventful, highlighting the importance of vigilant monitoring and prompt management of such complications. This case underscores the need for careful attention during the use of cardiac positioners to minimize adverse events and ensure favorable patient outcomes. [ABSTRACT FROM AUTHOR]

A 57-year-old male presented with dyspnea and an enlarged cardiac silhouette on a chest X-ray. Further evaluation with contrast-enhanced computed tomography revealed a giant heterogeneous mediastinal mass, ~8.9 × 7.3 × 12.2 cm, with peripheral calcifications. Surgical resection was performed via a left thoracotomy approach using the left fifth intercostal space. Cardiopulmonary bypass was established through the femoral vessels for safer and more controlled resection. The tumor, contiguous with the left atrium, was successfully excised using two Endo GIA staplers. Pathological examination confirmed the diagnosis of schwannoma. This case demonstrates that the left thoracotomy approach with cardiopulmonary bypass and the use of Endo GIA staplers is a feasible and effective option for resecting large, well-defined cardiac schwannomas., Competing Interests: None declared., (Published by Oxford University Press and JSCR Publishing Ltd. © The Author(s) 2024.)

Introduction: This study aims to clarify the good inflow site for saphenous vein grafts (SVG) in minimally invasive off-pump coronary artery bypass grafting (mini-CABG), between the ascending aorta, the internal thoracic arteries (ITAs) and the left axillary artery (LAA)., Methods: This retrospective study included 126 patients who underwent Mini-CABG at our center between January 2014 and July 2023. Patients were divided into three groups according to the SVG inflow site for patency comparison: Aorta group ( n  = 56), LAA group ( n  = 23), and ITA group ( n  = 47)., Results: There were 84 males, with mean age of 65.9 ± 7.0 years. There were no significant differences in preoperative characteristics between groups. Mean operation times were 254.6 ± 72.2, 213.7 ± 57.6, and 253.0 ± 81.2 min, and the average numbers of distal anastomoses were 2.9 ± 0.9, 2.4 ± 0.7 and 2.9 ± 1.1 in the Aorta, ITA and LAA groups respectively. Days in intensive care, hospital stay, and major complications did not differ between the groups. Early patency of SVG did not significantly differ among groups: 93.0% in the Aorta group, 98.0% in the ITA group, and 100% in the LAA group. Mean follow-up period was 136.7 ± 295.7 days, and follow-up coronary CTA revealed 18 SVG occlusions (Aorta group n  = 8, ITA group n  = 5, LAA group n  = 5). The Kaplan-Meier curve for SVG patency rates did not show any significant differences among the three groups., Conclusion: The ascending aorta, the ITAs, and the LAA serve as reliable inflow sites with similar results in mini-CABG., 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 Ushioda, Hirofuji, Yoongtong, Sakboon, Cheewinmethasiri, Lokeskrawee, Patumanond, Lawanaskol, Kamiya and Arayawudhikul.)
