Undiagnosed Stanford type A aortic dissection : a rare survival report
No full textAcute aortic dissection is a life-threatening conditions with a high mortality rate within the first 24 h since presentation, if left untreated. Nevertheless the setting may be chronic and stable. We present a rare case of a misdiagnosed and unoperated Stanford type A aortic dissection in a 78-year old woman with stable computed tomography features at the second year of clinical follow-up
A novel pulsatile platform for the ex-vivo evaluation of early remodelling events in human saphenous veins
Full text linkTechnology applied to the cultural heritage sector has not (yet) exceeded our humanity
No full textChanges in traditional sectors, such as cultural heritage, have stemmed from technological innovations, which brought new opportunities for the valorization of cultural heritage, as well as new competences requirements. With a specific focus on cultural organizations, the technology can provide greater efficiency in the coordination of processes and facilitate the development of new activities that can generate economic returns. Touristic guides have a prominent role in cultural heritage valorization as they contribute to deliver a full and comprehensive experience to the visitors. Therefore, the technology adoption and usage of the touristic guides should have a direct impact on the valorization of cultural heritage through ICTs. In this paper, we aim at identifying the sensemaking that each actor confers to the technological innovations, and its impact on cultural heritage valorization
Percutaneous closure of femoral pseudaneurysm after TAVR
No full textFully percutaneous transfemoral transcatheter aortic valve replacement (TF-TAVR) is currently the standard of the catheter-based treatment of severe aortic stenosis patients. Even though experience, lower delivery catheters profile and improved vascular closure devices performances have resulted in an overall reduction of both vascular and bleeding complications after TAVR, femoral pseudoaneurysm due to incomplete local hemostasis may occur, prolonging the in-hospital length of stay, causing discomfort to the patient and potentially evolving in serious consequences affecting the outcome. We report two successful percutaneous ultrasound-guided closure of both the main and secondary femoral access pseudoaneurysm
Aneurysms of the coronary arteries: one case report
No full textTrue aneurysms of the coronary arteries are very uncommon. In our institution, from December 1982 to April 1987, in more than 2500 coronarographies, we observed only one case whose angiographic findings revealed a real fusiform aneurysm (at least 3 times the diameter of the original vessel) of the right coronary artery. The same patient exhibited a left anterior descending artery ectasia too, as we already noted in other cases not included in the present report. The other coronary arteries showed no associated lesions. Clinical findings included a previous myocardial inferior infarction and typical precordial effort pain with a basal and stress ECG showing non specific ST-T wave abnormalities. The patient underwent right coronary endoaneurysmectomy with interposition of a saphenous vein graft. Postoperative course was uneventful and 8 months after surgery the patient was asymptomatic, and basal and effort ECG showed no ischemic modification. Control angiogram revealed an optimal anatomical reconstruction with no further evolution of the left anterior descending artery dilatation. The distinction between vessel dilation and an aneurysm is discussed
Huge Left Atrial Myxoma and Concomitant Silent Coronary Artery Disease in a Young Man
Full text linkSevere but silent coronary artery disease may rarely exist in young patients with a low-risk profile but with a family history of coronary artery disease. We describe the case of a 33-year-old Caucasian male with progressive shortness of breath caused by a huge left atrial myxoma who was diagnosed to have significant coronary artery disease in the preoperative assessment. After investigations, the patient underwent resection of the left atrial tumor and coronary artery bypass grafting (CABG) with a successful outcome. Even in the case of a young male, it may be prudent to investigate silent coronary artery disease in the presence of cardiovascular risk factors and family history of coronary artery disease. The learning objective of this case is to debate about the usefulness of a preoperative coronary study even in the young population with cardiac nonischemic pathologies (ie, valve pathology, cardiac tumors, etc.)
Coronary artery disease associated with severe mitral and tricuspid valve regurgitation after left Pneumonectomy: report of a successful hybrid procedure
Full text linkThe literature concerning heart surgery after pneumonectomy is still poor. Moreover, there is still a lack of a standardized approach to such a patient in the decision-making process. Here, we report a case of a patient who had previously had left pneumonectomy for malignancy and who had coronary artery disease and mitral and tricuspid regurgitation treated with a hybrid procedure
