Spontaneous coronary artery dissection (SCAD) is the formation of a false lumen within a vessel wall, with an accumulation of blood leading to vessel occlusion, mimicking symptoms of acute myocardial infarction (AMI). Here, we discuss the case of a middle-aged woman with STEMI who was found to have coronary artery dissection on coronary angiography during left heart catheterization. Clinicians should have a high suspicion of SCAD in young females presenting with AMI without traditional risk factors for coronary artery disease. Such patients should receive urgent angiography. Once the diagnosis is confirmed, there are no clear guidelines for treating AMI secondary to SCAD. Hemodynamically stable patients can be managed with the immediate initiation of antiplatelet therapy and beta-blockers. Thrombolytic therapy is avoided due to the risk of dissection and intramural hematoma. Coronary artery bypass graft (CABG) is indicated in patients with multiple vessel involvement or patients who have had a primary coronary intervention fail. Bioresorbable vascular scaffolds (BVS) may be a better option in STEMI or hemodynamic instability. However, current treatment strategies are based on expert opinion and a few case studies.

Objectives: As is well known, plaque morphology plays an important role in the hemodynamics of stenotic coronary arteries, thus their clinic outcomes. However, so far, there has been no research on how the cross-sectional shape of a stenotic lumen affects its hemodynamics. Therefore, this study aims to explore the impact of plaque cross-sectional shape on coronary hemodynamics under mild or moderate stenosis conditions (diameter stenosis degree ≤50 %).

Purpose: To report a successful case of vision restoration and macular reperfusion following branch retinal artery occlusion (BRAO) using pars plana vitrectomy with undermining the artery off the retinal bed.
Methods: This case report involves a 75-year-old patient who was diagnosed immediately with BRAO following cardiac catheterization procedure. An embolus at the superior retinal artery bifurcation was noted.
Diagnosis of atrial cardiomyopathy: from the electrocardiogram to the new opportunities with multimodality imaging.

Atrial cardiomyopathy (AC) has been defined by the European Heart Rhythm Association as "Any complex of structural, architectural, contractile, or electrophysiologic changes in the atria with the potential to produce clinically relevant manifestations".1 The left atrium (LA) plays a key role in maintaining normal cardiac function; in fact atrial dysfunction has emerged as an essential determinant of outcomes in different clinical scenarios, such as valvular diseases, heart failure (HF), coronary artery disease (CAD) and atrial fibrillation (AF). A comprehensive evaluation, both anatomical and functional, is routinely performed in cardiac imaging laboratories.

Aims: Coronary microvascular dysfunction (CMD) is a heterogeneous condition defined by reduced coronary flow reserve (CFR). The new index 'microvascular resistance reserve' (MRR) has been developed, but its role is unclear. We investigate the relationships between functional indices in ANOCA (angina and non-obstructive coronary arteries) patients and evaluate the hemodynamic features of different CMD subtypes.

Cardiac rehabilitation (CR) is a cornerstone of heart disease (HD) management, enhancing functional capacity and quality of life. Hybrid cardiac rehabilitation (hCR), combining supervised center-based sessions with synchronous, real-time telerehabilitation at home, offers an alternative to conventional CR to overcome logistical barriers such as facility limitations, distance, and pandemic-related disruptions. This randomized controlled trial evaluated the noninferiority of hCR compared to standard CR in improving functional capacity in patients with chronic heart disease, including those with stable coronary artery disease.
