Research on predicting radiographic exposure time in imaging based on neural network prediction models.
Clin Neurol Neurosurg
January 2025
The Second Affiliated Hospital of Guangxi Medical University, Nanning, Guangxi, China. Electronic address:
Objective: To explore the anatomical and clinical factors that affect the radiographic exposure time in radial artery cerebral angiography and to establish a model.
Method: A total of 210 patients who underwent radial artery cerebral angiography at this center from September 2021 to May 2022 were selected, and their anatomical and clinical factors were analyzed to evaluate the correlation between these factors and the duration of radiographic exposure. A related neural network prediction model was established.
Aortic valve repair in adults: long-term clinical outcomes and echocardiographic evolution in different valve repair techniques.
Eur J Cardiothorac Surg

Department of Cardiothoracic Surgery, Division of Heart and Lung Disease, Utrecht University Medical Center, Utrecht, The Netherlands.
Objective: Aortic valve repair/sparing have been established as effective treatments for aortic regurgitation and/or aortic aneurysms. However, concerns remain regarding long-term durability, reproducibility, and patient selection. This study aims to asses long-term clinical and echocardiographic outcomes, with a focus on aortic regurgitation grade and left ventricular ejection fraction evolution, in adults undergoing these procedures.

Department of Cardiovascular Surgery, Nanfang Hospital, Southern Medical University, Guangzhou, China.
Background: There are few reports about the one-stage surgery of transcatheter aortic valve replacement (TAVR) + mitral valve transcatheter edge-to-edge repair (M-TEER) around the world. TAVR + M-TEER surgery is usually performed under the simultaneous guidance of digital subtraction angiography (DSA) and echocardiography. There is no report of TAVR surgery assisted only by echocardiography all over the world.

Background: Nonocclusive mesenteric ischemia (NOMI), a subtype of acute mesenteric ischemia, is primarily caused by mesenteric arterial vasoconstriction and decreased vascular resistance, leading to impaired intestinal perfusion.Commonly observed after cardiac surgery, NOMI affects older patients with cardiovascular or systemic diseases, accounting for 20-30% of acute mesenteric ischemia cases with a mortality rate of ∼50%. This review explores NOMI's pathophysiology, clinical implications in aortic dissection, and the unmet needs in diagnosis and management, emphasizing its prognostic significance.

Aortic arch anomalies represent a range of congenital vascular malformations resulting from disruptions in the typical embryological development of the aortic arch and its branches. These anomalies, which vary widely in their presentation, can lead to significant clinical symptoms depending on their structure and position. We report the case of a 75-year-old male with intermittent hypertension, palpitations, and episodic warmth in the upper body.
