Integrated Multi‐Omics Reveals Cellular States and Microenvironmental Remodeling in Coexisting DCIS and IDC

Advanced Science, EarlyView.
Coexisting DCIS and IDC samples are profiled using spatial transcriptomics, single‐cell RNA sequencing, and single‐cell DNA sequencing. Integrative multi‐omics analysis reveals distinct malignant epithelial and microenvironmental features between DCIS and IDC, which are further validated using Xenium and multiplex immunohistochemistry.

Implantable Systems for Cardiovascular Treatment and Monitoring: Comparative Insights From Intracardiovascular and Extracardiovascular Technologies

Advanced Intelligent Systems, EarlyView.
A unifying device–cardiovascular interface framework is presented to classify implantable cardiovascular technologies as intracardiovascular blood‐contacting systems or extracardiovascular tissue‐only and blood‐handling architectures. Cross‐class comparison across shared semiquantitative criteria, including blood‐contact burden, biomimicry ...

ATHEROSCLEROSIS OF THE INTERNAL MAMMARY ARTERY IN PATIENTS UNDERGOING CORONARY ARTERY BYPASS GRAFTING [PDF]

Acta Medica Iranica, 2003
In patients requiring coronary artery bypass grafting (CABG), usually at least one of the internal mammary arteries is used. This study evaluates the degree of atherosclerotic involvement of the internal mammary artery (IMA) in patients undergoing CABG ...

REVASCULARIZACIÓN MIOCÁRDICA CON AMBAS ARTERIAS MAMARIAS INTERNAS, UN RETO PARA LOS CIRUJANOS CARDIOVASCULARES ACTUALES / Myocardial revascularization with both internal mammary arteries, a challenge for cardiovascular surgeons nowadays [PDF]

CorSalud, 2009
The left internal mammary artery is currently the most common graft in surgical myocardial revascularization. However, in spite of the works showing the effectiveness of the use of both mammary arteries, this technique remains a controversial topic in ...

Silk Fibroin for Cardiovascular Medical Devices: Review of Material Properties, Applications, and Clinical Potential

Advanced NanoBiomed Research, EarlyView.
Silk fibroin is an attractive natural biomaterial that can be engineered into diverse cardiovascular constructs, including vascular grafts, cardiac patches, heart valves, and stent coatings. Its tunable biological and mechanical properties have driven substantial preclinical progress; however, widespread clinical translation in cardiovascular ...

ACE2 and AT4R are present in diseased human blood vessels

European Journal of Histochemistry, 2009
A growing body of evidence suggests that the angiotensin II fragments, Ang(1-7) and Ang(3-8), have a vasoactive role, however ACE2, the enzyme that produces Ang(1-7), or AT4R, the receptor that binds Ang (3-8), have yet been simultaneously localised in ...

Coronary artery fistulas as a rare cause of heart failure and ventricular arrhythmia, associated with multiple large vessel fistulas

Radiology Case Reports, 2023
Coronary artery fistulas are abnormal connections between the coronary arteries with a heart chamber or any of the major blood vessels. Fistulous connections between systemic arteries and pulmonary vessels are even less frequent.

Diagnostic Accuracy and Feasibility of Quantitative Flow Ratio at Low Frame Rate Angiography: The Prospective Multicentre Australian AVALON Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Quantitative Flow Ratio (QFR) is a well‐established, non‐hyperemic, angiographic, wire‐free predictor of ischemia when compared to Fractional Flow Reserve (FFR). However, its diagnostic accuracy at low frame rates (< 10 frames/second), commonly used in contemporary practice to minimize radiation exposure, has not been evaluated ...

The combination of breast necrosis and chylothorax following the OPCAB [PDF]

Journal of Cardiovascular and Thoracic Research, 2016
Due to long term patency, the internal mammary artery is considered as a conduit of choice for revascularization of the left anterior descending coronary artery.

Mechanisms and Management of Acquired Aseptic Intracardiac Communications After Transcatheter Aortic Valve Implantation: Single‐Center Case Series Insights

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Acquired aseptic intracardiac communications (AICCs) are rare but clinically relevant structural complications following transcatheter aortic valve implantation (TAVI), typically resulting from mechanical injury to the aortic annulus, interventricular septum, or adjacent structures.
