Structural constrained virtual histology staining for human coronary imaging using deep learning [PDF]

arXiv, 2022
Histopathological analysis is crucial in artery characterization for coronary artery disease (CAD). However, histology requires an invasive and time-consuming process. In this paper, we propose to generate virtual histology staining using Optical Coherence Tomography (OCT) images to enable real-time histological visualization.

A Case of Acute Myocardial Infarction with the Anomalous Origin of the Right Coronary Artery from the Ascending Aorta above the Left Sinus of Valsalva and Left Coronary Artery from the Posterior Sinus of Valsalva [PDF]

, 2009
Coronary anomalies are rare angiographic findings. Moreover, there are few reports of cases of an anomalous origin of the right coronary artery from the left sinus of Valsalva and of the left coronary artery from the posterior sinus of Valsalva. Here, we

A shocking lead in the coronary sinus [PDF]

Europace, 2009
Placement of leads into the coronary sinus (CS) is now routinely used for cardiac resynchronization therapy. However, the CS can also be used for the placement of defibrillator shock leads. There is evidence demonstrating that CS leads in situ for the short and medium term can be successfully removed utilizing percutaneous methods.

Late Diagnosis of Anomalous Aortic Origin of a Coronary Artery from the Inappropriate Sinus of Valsalva during Investigation of Chest Pain

Case Reports in Cardiology, 2018
In this work are reported two cases of anomalous aortic origin of a coronary artery (AAOCA), with the left main coronary artery (LMCA) arising at the right sinus of Valsalva in a 77-year-old woman and in a 79-year-old man submitted to angiography after ...

Responses to stimulation of coronary and carotid baroreceptors and the coronary chemoreflex at different ventricular distending pressures in anaesthetised dogs [PDF]

, 2001
Stimulation of left ventricular mechanoreceptors was believed not only to exert important effects on the circulation, but also to influence the responses to baroreceptor reflexes.

Endovascular Treatment of Malfunctioning Dialysis Fistulas: A Multicenter Retrospective Analysis Comparing Transradial and Conventional Transvenous Access

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Venous outflow is the favored access for endovascular management of dialysis fistulas. However, transradial access (TRA) offers advantages in specific clinical scenarios. The study aims to compare the efficacy, feasibility, and safety of TRA and transvenous access (TVA) in the endovascular management of malfunctioning dialysis ...

Predictive value of pituitary tumor morphology on outcomes and complications in endoscopic transsphenoidal surgery

World Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 8, Issue 4, Page 321-329, December 2022., 2022
Abstract Purpose Endoscopic transsphenoidal surgery (ETSS) is an increasingly utilized approach for resection of pituitary tumors. Prior studies have evaluated preoperative tumor size, location, and extent as prognostic factors for surgical resection. There is little data on the relationship between preoperative pituitary tumor radiographic morphology ...
