Multicenter Assessment of Grafts in Coronaries: Midterm Evaluation of the C-Port Device (the MAGIC Study)

Conclusions The C-Port device is safe and effective in creating the distal anastomosis with equivalent patency rates to hand-sewn grafts at 12 months. When compared with hand-sewn anastomoses from a recent large prospective trial, the C-Port device demonstrated a statistically significant reduction in midterm graft occlusion. Further studies are required to evaluate its effect in less invasive coronary surgery.

ConclusionThe CABG of the RCA with anomalous origin can be done safely with excellent early and midterm results. Proximal RCA ligation is an essential step to the success of CABG, but intraoperative challenge testing is required to confirm the sufficiency of the internal thoracic artery graft to reperfuse the supplied territory.

Coronary CT angiography (CCTA) is an accurate non-invasive tool for the evaluation of coronary artery bypass graft (CABG). However, inability to sustain a long breath-hold, high heart rate (HR) and atrial fibrillation may affect image quality. Moreover, radiation exposure is still a matter of some concern. A scanner combining 0.23-mm spatial resolution, new iterative reconstruction and fast gantry rotation time has been recently introduced in the clinical field. The aims of our study were to evaluate interpretability, radiation exposure and diagnostic accuracy of CCTA performed with the latest generation of cardiac-CT scan...

CONCLUSIONS: Prior CTCA improves graft detection at the time in coronary angiography and reduces the time necessary to localize graft ostium, the total procedure time duration, and volume of contrast media used. PMID: 31235457 [PubMed - as supplied by publisher]

Abstract Congenital Bochdalek diaphragmatic hernia (DH) is often diagnosed incidentally in adulthood. It is recommended that all cases of DH be repaired immediately at diagnosis since acute presentation after the complications have already developed has higher morbidity and mortality. A 47-year-old male presented with Grade III angina and dyspnea. A routine chest radiograph revealed bowel shadows in the right thorax, and subsequent computerized tomography (CT) scan confirmed the same. Coronary angiogram revealed coronary artery disease which needed surgery. Off-pump coronary artery bypass grafting followed by DH r...

If all three major coronary branches have similar degree of stenosis, the radionuclide used for perfusion study will have equal uptake in all regions of the myocardium. Thus a balanced three vessel coronary artery disease can produce a false negative myocardial perfusion scan. This situation is called balanced myocardial ischemia. In most cases this is picked up by the treadmill ECG usually done along with stress myocardial perfusion imaging. Since the ECG findings of myocardial ischemia does not depend on the relative perfusion in the coronary tree, ischemic changes will be noted in treadmill ECG even when nuclear ...

We report a case of a 41-year male patient admitted due to acute coronary syndrome presented as unstable angina. Coronary angiography showed a 100% ostial lesion of left main coronary artery and 90% occlusion of the right coronary artery ostium. Subsequent Computed Tomography Angiography (CTA) scan showed prominent thickening of the aortic wall. The Venereal Disease Research Laboratory (VDRL) test was titrated to 1/16. The patient was referred for coronary artery bypass graft (CABG).Keywords:Acute coronary syndrome,Computed Tomography Angiography,Coronary Angiography,Coronary ostial stenosis,Left main coronary artery,right...

Conclusions: The addition of CT angiography measurements of the epicardial adipose tissue overlying the left anterior descending coronary artery may enhance preoperative surgical planning for this procedure, thereby reducing the instances of procedural changes.

In conclusion, we report a case of NCC associated with complex three-vessel coronary artery disease. Furthermore, the combination of massive pulmonary embolism and clots in the left ventricle made his management even more challenging. PMID: 28163145 [PubMed - as supplied by publisher]

AbstractCoronary CT angiography (CCTA) suffers from a reduced diagnostic accuracy in patients with heavily calcified coronary arteries or prior myocardial revascularisation due to artefacts caused by calcifications and stent material. CT myocardial perfusion  imaging (CTMPI) yields high potential for the detection of myocardial ischemia and might help to overcome the above mentioned limitations. We analysed CT single-phase perfusion using high-pitch helical image acquisition technique in patients with prior myocardial revascularisation. Thirty-six pati ents with an indication for invasive coronary angiography (28 with...

We examined the red thrombi histopathologically. Hematoxylin and eosin staining revealed high-grade spindle cell sarcoma with variable degrees of atypia and nuclear polymorphism (Panel E). There were no specific findings in the Whole-body Positron Emission Tomography and Computed Tomography scan. To confirm the definitive diagnosis, she underwent coronary artery bypass surgery (saphenous vein graft to RCA) 4 months after PCI. During the surgery, two small solid masses were detected on the surface of the distal RCA. Intraoperative biopsy confirmed intimal sarcoma. Cryothermy coagulation was performed during the surgery, and...
