Myocardial revascularization in patients presenting with an anterior mediastinal mass poses considerable challenges. In this report, we outline two cases involving patients with anterior mediastinal masses who underwent surgical resection alongside concurrent myocardial revascularization. One patient underwent coronary artery bypass graft surgery, while the other was treated by percutaneous coronary intervention with drug-eluting stent placement. Both patients fully recovered from the relative procedures and were discharged within two weeks post-surgery, ultimately diagnosed with thymoma. The concomitant intervention offered the advantage of promptly addressing both conditions, and it was performed safely through a collaborative multidisciplinary effort.

The management of patients on direct oral anticoagulants (DOACs) who require an emergency cardiac surgery has been disputed in Japan. Recently, the use of andexanet alfa as an antidote for apixaban and rivaroxaban, is approved in the setting of life-threating or uncontrollable major bleeding. However, the efficacy and safety of andexanet alfa have been investigated. We report a case of 72-year-old man taking rivaroxaban who required the emergency coronary artery bypass grafting. He received andexanet alfa prior to the operation. Heparin resistance was noted before starting cardiopulmonary bypass. Consideration should be given to the use of andexanet alfa before or during cardiopulmonary bypass.

Myocardial infarction is among the top causes of mortality worldwide. Survivors may also experience several complications. Infarct-related torsade de pointes (TdP) is an uncommon complication. In the context of myocardial infarction, coronary artery bypass graft (CABG) surgery is the prevalent therapeutic modality associated with several early and late complications. Ventricular tachyarrhythmias, including TdP, because of electrical inhomogeneity, would potentially be a lethal complication of CABG. Here, we report the occurrence of medically intractable TdP in the presence of an uncommon case of a post-CABG retrosternal hematoma. Arrhythmia was properly resolved after hematoma removal surgically. It showed the possibility of a \"cause and effect\" relationship between these two complications. This unique case emphasizes the post-CABG medically-resistant TdP, considering the mechanical pressure effect of retrosternal hematoma that stimulates this potentially malignant arrhythmia, especially in the absence of electrolyte disturbances and evident symptoms of ongoing ischemia.

This case series describes the safety and effectiveness of superficial parasternal intercostal plane catheters for poststernotomy pain control in 4 patients who underwent multivessel coronary artery bypass grafting. Patients had reduced sternal pain and opioid consumption while the catheters ran continuously for 72 hours without complications. Our experience suggests the effectiveness of parasternal blocks can be safely prolonged with catheters, and they can be a useful addition to pain management strategies for this patient population.

This case challenges the conventional preference for coronary artery bypass grafting (CABG) over percutaneous coronary intervention (PCI) in patients with diabetes, left main coronary artery disease (LMCAD) and multivessel disease. Current guidelines generally recommend CABG, especially in the context of LMCAD. However, our case involves a male patient with diabetes with LMCAD and extensive multivessel disease who was successfully treated with PCI, demonstrating a favorable outcome. Despite the high-risk profile, including a SYNTAX score of 28, the PCI approach was selected. This decision was supported by evidence suggesting comparable outcomes between PCI and CABG in similar patients. Our case highlights the potential of PCI as not just a viable, but potentially superior alternative in specific high-risk patients with diabetes, contrary to the prevailing belief in favor of CABG for all patients with left main involvement.

BACKGROUND: Coronary artery bypass grafting (CABG) using the right gastroepiploic artery (RGEA) is a well-established, safe procedure. However, problems with RGEA grafts in subsequent abdominal surgeries can lead to fatal complications. This report presents the first case of right hepatectomy for hepatocellular carcinoma after CABG using the RGEA.
METHODS: We describe a case in which a right hepatectomy for an 81-year-old male patient with hepatocellular carcinoma was safely performed after CABG using a RGEA graft. Preoperatively, three-dimensional computed tomography (3D- CT) images were constructed to confirm the run of the RGEA graft. The operation was conducted with the standby of a cardiovascular surgeon if there was a problem with the RGEA graft. The RGEA graft had formed adhesions with the hepatic falciform ligament, necessitating meticulous dissection. After the right hepatectomy, the left hepatic lobe descended into the vacated space, exerting traction on the RGEA. However, this traction was mitigated by suturing the hepatic falciform ligament to the abdominal wall, ensuring stability of the RGEA. There were no intraoperative or postoperative complications.
CONCLUSIONS: It is crucial to confirm the functionality and anatomy of the RGEA graft preoperatively, handle it gently intraoperatively, and collaborate with cardiovascular surgeons.

BACKGROUND: Polyarteritis Nodosa (PAN) is a systemic vasculitis (SV) historically thought to spare the coronary arteries. Coronary angiography and contemporary imaging reveal coronary stenosis and dilation, which are associated with significant morbidity and mortality. Coronary arteries in PAN are burdened with accelerated atherosclerosis from generalized inflammation adding to an inherent arteritic process. Traditional atherosclerotic risk factors fail to approximate risk. Few reports document coronary pathology and optimal therapy has been guarded.
METHODS: Database publication query of English literature from 1990-2022.
RESULTS: Severity of coronary involvement eludes laboratory monitoring, but coronary disease associates with several clinical symptoms. Framingham risk factors inadequately approximate disease burden. Separating atherosclerosis from arteritis requires advanced angiographic methods. Therapy includes anticoagulation, immunosuppression and revascularization. PCI has been the mainstay, though stenting is confounded by vagarious alteration in luminal diameter and reports of neointimization soon after placement.
CONCLUSIONS: When graft selection avoids the vascular territory of SV\'s, CABG offers definitive therapy. We have contributed report of a novel CABG configuration in addition to reviewing, updating and discussing the literature. Accumulating evidence suggests discrete clinical symptoms warrant suspicion for coronary involvement.

UNASSIGNED: Saphenous vein graft aneurysms are rare complications after coronary artery bypass grafting that carry serious complications. Less than 10 case reports of autopsy findings consistent with ruptured saphenous vein grafts exist in the literature. We report a case of a female presenting at autopsy who, after coronary artery bypass grafting 20 years prior, demonstrated findings of a saphenous vein graft aneurysm and rupture. With limited evidence from medical records, this case highlights a need for patients with previous coronary artery bypass grafting to be properly monitored to detect minute graft changes before aneurysm formation and rupture as seen in our decedent.

Different causes have been described for secondary lymphedema as reported in this article. A 75-year-old man was diagnosed with lymphedema about one decade after saphenous harvesting for coronary artery bypass surgery. It took two years for him to find out his diagnosis and receive the proper treatment. After standard complete decongestive therapy, his volume and pain decreased and his quality of life was improved, especially its physical aspect. It is important to recognize the possibility of lymphedema development after saphenous harvesting among patients undergoing coronary artery bypass surgery to prevent significant disturbance of quality of life with timely management.

Myocardial bridging is congenital anomaly characterized by segment of epicardial coronary arteries passing through the myocardium. Various ischemic conditions are related with this pathology. We report a case of myocardial bridging that was complicated with acute anterior myocardial infarction and a review of the literature. The patient was treated successfully with coronary bypass graft surgery after unsuccessful percutaneous intervention.
