Cost‐Utility Analysis of Different Treatment Modalities in Patients Undergoing Percutaneous Coronary Intervention: Thai PCI Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Cost‐utility analyses of percutaneous coronary interventions (PCIs) provide valuable insights into the economic value of these procedures. However, data is lacking, particularly in developing countries with limited resources. Aims This analysis aimed to compare the cost‐utility of different treatment modalities used for PCI patients

Honeycomb or Lotus Root‐Like Intracoronary Pattern: Insights From Optical Coherence Tomography of a Recanalized Thrombus

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Spontaneous recanalized coronary thrombus (SRCT) has been identified in autopsy studies as multiple interconnected channels separated by thin septa. Despite its potential clinical significance, SRCT remains underdiagnosed. Recent advances in intracoronary imaging, including optical coherence tomography (OCT), have elucidated its ...

Optical coherence tomography angiography in retinal diseases

Journal of Ophthalmic and Vision Research, 2016
Optical coherence tomography angiography (OCTA) is a new, non-invasive imaging system that generates volumetric data of retinal and choroidal layers. It has the ability to show both structural and blood flow information. Split-spectrum amplitude-decorrelation angiography (SSADA) algorithm (a vital component of OCTA software) helps to decrease the ...
