What eyes do not see the heart does not grieve over? The role of intracoronary imaging in acute myocardial infarction: a case report.

Background: The evaluation of a three-dimensional structure with a two-dimensional imaging technique makes intracoronary diagnostic techniques essential, especially in the setting of acute myocardial infarction (AMI) when no apparent coronary lesions are detected. Expert consensus recommend their use in certain scenarios such as angiographically ambiguous disease and identification of the culprit lesion. Although both intravascular ultrasound and optical coherence tomography (OCT) allow the characterization of the atherosclerotic plaque and assess the immediate and long-term results of stent implantation, they have their own benefits and limitations that make them ideal for different types of coronary lesions.

Article Synopsis
- The study aimed to assess the practical use of intracoronary assessment (ICA) techniques and their effect on the treatment decisions for coronary artery disease (CAD).
- Although traditional coronary angiograms are commonly used for diagnosing vessel narrowing, ICA provides improved three-dimensional imaging and physiological insights, potentially leading to better patient outcomes.
- Results from 1,135 patients indicated that ICA influenced clinical decisions in a significant portion of cases, often resulting in fewer surgical interventions without increasing the risk of major adverse cardiac events in the following year.
Optical coherence tomography and coronary revascularization: from indication to procedural optimization.

Angiography alone is the most commonly used imaging modality for guidance of percutaneous coronary interventions. Angiography is limited, however, by several factors, including that it only portrays a low resolution, two-dimensional outline of the lumen and does not inform on plaque composition and functional stenosis severity. Optical coherence tomography (OCT) is an intracoronary imaging technique that has superior spatial resolution compared to all other imaging modalities.

Cardiac Surgery Unit, IRCCS San Raffaele Scientific Institute, 20132 Milan, Italy.
Background: Myocardial contrast two-dimensional echocardiography (MC-2DE) is widely used to address alcohol septal ablation (ASA) in obstructive hypertrophic cardiomyopathy (HCM). Owing to its limited cut-planes, MC-2DE may inaccurately identify the contrast misplacement associated with an unsuccessful or complicated ASA outcome.
Objective: The aim of this study was to assess the added value of myocardial contrast three-dimensional echocardiography (MC-3DE) compared with MC-2DE to identify the appropriate matching between the target septal zone (TSZ) and coronary artery branch for safe and long-term effective ASA in HCM patients.
Intra-Slice Motion Correction of Intravascular OCT Images Using Deep Features.
IEEE J Biomed Health Inform
May 2019
Intra-slice motion correction is an important step for analyzing volume variations and pathological formations from intravascular imaging. Optical coherence tomography (OCT) has been recently introduced for intravascular imaging and assessment of coronary artery disease. Two-dimensional (2-D) cross-sectional OCT images of coronary arteries play a crucial role to characterize the internal structure of the tissues.
