Background: Robotically assisted totally endoscopic coronary artery bypass graft surgery (TECABG) is an innovative minimally invasive procedure requiring proof of immediate- and short-term patency of grafts to compete with conventional bypass surgery or percutaneous coronary interventions. The purpose of this study was to evaluate the combination of invasive and noninvasive coronary angiography methods in innovative cardiac surgery as an approach to optimal quality control.
Methods: In 86 patients after robotic coronary surgery (62 arrested-heart TECABG, 20 through sternotomy with robotically assisted anastomoses, 4 beating-heart TECABG), intraoperative coronary angiography was performed with a mobile C-arm. All patients underwent multislice computed tomography angiography, and invasive coronary angiography was performed in 48 patients within 3 months after surgery.
Results: Bypass grafts could be visualized by intraoperative angiography in 84 patients (98%). Spasm of target vessels or bypass grafts, or both (reversible after intraluminal nitroglycerine application), was observed in 47%. In 9 patients, surgical revisions were performed owing to inadequate revascularization results. No angiography-related complications occurred. The sensitivity and specificity of multislice computed tomography for the evaluation of graft patency were 100% and 97%, respectively. The visualization of distal anastomoses and distal target vessels was good in 90% but limited in 10% because of artifacts, limited spatial resolution, and high image noise.
Conclusions: The combination of intraoperative angiography and postoperative multislice computed tomography allows safe and high-quality evaluation of immediate- and short-term outcome in innovative robotic coronary surgery. Immediate revisions of bypass grafts are possible, to ensure that all patients leave the operating room with patent bypass grafts.

Unlabelled: This study investigates the anatomical prerequisites that could contribute to the development of this condition.
Material And Methods: Using multi-slice computed tomography (MSCT), the study examined the structure and relationships of key anatomical features, including the alveolar process, sinus wall thickness, and the position of the teeth in relation to the maxillary sinus.
Results: The results revealed that the lower wall of the maxillary sinus is predominantly formed by the alveolar process, with significant variability in wall thickness, especially between the central and lateral regions.

Article Synopsis
- This study investigates the effectiveness of single-slice versus multi-slice computed tomography (CT) methods in analyzing body composition in patients with oesophagogastric cancer, focusing on their correlation and impact on survival rates.
- Researchers examined CT scans of 504 patients, comparing measurements of skeletal muscle, subcutaneous, visceral, and intermuscular adipose tissue, finding high correlation and narrow limits of agreement between the two methods.
- Results indicate that both measurement techniques offer similar insights into body composition, suggesting that the clinical use of multi-slice analyses may be beneficial but requires further exploration for optimal application.

Introduction: Nonbacterial thrombotic endocarditis (NBTE) is a rare cardiac manifestation in patients with advanced malignancies of the lungs, pancreas, gynecological system, and gastrointestinal tract. It is often confirmed postmortem by histopathological evidence of sterile platelet-fibrin deposits attached to the endocardium, most often on heart valves. To the best of our knowledge, our case is the first to report multiple heart lesions caused by the systemic effect of cholangiocarcinoma.

Background: Older adults with cancer are at an increased risk of treatment related toxicities and early death. Routinely collected clinico-demographic characteristics inadequately explain this increased risk limiting accurate prognostication. Prior studies have suggested that altered body composition and frailty are independently associated with worse survival among older adults with cancer; however, their combined influence remains unclear.

Background: The Anomalous Origin of the Right Coronary Artery from the Left Coronary Sinus (ARCA-LCS) is a rare congenital cardiac condition where the right coronary artery emerges from the left sinus instead of the right coronary sinus of Valsalva. The clinical significance of ARCA-LCS lies in its potential to cause myocardial ischemia or sudden cardiac death, particularly under physical exertion. In this case, a patient experienced sudden cardiac arrest during sexual activity, which has not previously been reported.
