Non-invasive pressure-volume loop derived temporal elastance, contractility, and efficiency indices for assessing Duchenne muscular dystrophy patients.

Ejection fraction is commonly used to assess Duchenne muscular dystrophy-associated cardiomyopathy (DMDAC), but it may remain normal (wrongly) despite significant myocardial dysfunction in patients. Therefore, better indicators of myocardial dysfunction are needed for longitudinal (with time) assessment and treatment of DMDAC patients. This study evaluates non-invasive LV PV loop-derived elastance, contractility and efficiency in relation to EF for patients developing DMDAC.

Immediate breast reconstruction provides breast cancer patients with a valuable opportunity to restore breast shape. However, post-reconstruction breast asymmetry remains a common issue that affects patient satisfaction. This study aims to quantify breast asymmetry after surgery using magnetic resonance imaging (MRI) and assess its impact on both breast satisfaction and overall outcome satisfaction, offering scientific evidence to guide improvements in preoperative evaluation.

Department of Neurosurgery, Saitama Sekishinkai Hospital, 2-37-20 Irumagawa, Sayama, Saitama, 350-1305, Japan.
Purpose: To describe a case in which a right replaced posterior cerebral artery (PCA) was associated with an ipsilateral superior cerebellar artery (SCA) type persistent trigeminal artery (PTA) variant.
Methods: A 53-year-old man who had been diagnosed with chronic dissection of the left vertebral artery (VA) 4 months previously underwent follow-up magnetic resonance (MR) angiography using a 3-Tesla scanner.
Results: MR angiography showed a slightly dilated left VA at the terminal segment without interval change.
Assessing Acute Pericarditis with T1 Mapping: A Supportive Contrast-Free CMR Marker.
Tomography
November 2024
Department of Radiology, Azienda Ospedaliero Universitaria (A.O.U.), di Cagliari-Polo di Monserrato s.s. 554 Monserrato, 09045 Cagliari, Italy.
Objective: The purpose of this study was to explore the impact of pericardial T1 mapping as a potential supportive non-contrast cardiovascular magnetic resonance (CMR) parameter in the diagnosis of acute pericarditis. Additionally, we investigated the relationship between T1 mapping values in acute pericarditis patients and their demographic data, cardiovascular risk factors, clinical parameters, cardiac biomarkers, and cardiac function.
Method: This retrospective study included CMR scans in 35 consecutive patients with acute pericarditis (26 males, 45.
Iron Deficiency Promotes Intra-leaflet Haemorrhage-induced Aortic Valve Calcification: an Experimental Study.
Int J Surg
December 2024
Department of Emergency Medicine, Qilu Hospital of Shandong University, Jinan, China.
Background: Interleaflet haemorrhage (IH) plays a well-recognized detrimental role in calcified aortic valve disease (CAVD). However, IH-induced fibro-osteogenic responses in valvular interstitial cells (VICs) appear to be triggered under specific pathological conditions. Iron deficiency (ID), a common co-morbidity in CAVD, may influence these responses.
