Rationale: Embolization of a deployed stent is a rare complication and its mechanism remains unclear in most cases.
Patient Concerns: A 52-year-old man underwent coronary angiography for effort angina, revealing an 80% stenosis of the proximal left anterior descending (LAD) involving the distal left main (LM). After luminal sizing with intravascular ultrasound two drug-eluting stents were deployed (5.0 × 12 mm and 3.5 × 15 mm) to cover the LM-LAD lesion. After postdilatation, the proximal stent had disappeared from the LM.
Diagnoses: The missing stent was found in the right deep femoral artery.
Interventions: A new 5.0 × 15 mm stent was deployed onto the LM-LAD ostium, in overlapping with the previously implanted. Then, the stent migrated to the deep femoral artery was successfully retieved through the contralateral femoral artery.
Outcomes: The patient was discharged 2 days later, after an uneventful hospital stay.
Lessons: Stent deformation after postdilation is a possible causes of stent migration.

Clinical Outcomes of Cardiac Transplantation in Heart Failure Patients with Previous Mechanical Cardiocirculatory Support.

Heart failure (HF) remains a significant public health issue, with heart transplantation (HT) being the gold standard treatment for end-stage HF. The increasing use of mechanical circulatory support, particularly left ventricular assist devices (LVADs), as a bridge to transplant (BTT), presents new perspectives for increasingly complex clinical scenarios. This study aimed to compare long-term clinical outcomes in patients in heart failure with reduced ejection fraction (HFrEF) receiving an LVAD as BTT to those undergoing direct-to-transplant (DTT) without mechanical support, focusing on survival and post-transplant complications.

: The main aim of this study is to analyze the outcomes of NSTEMI admissions and test the relevance of TIMI as a risk score in a real-world setting. We also examine any potential social or health care disparities involved with outcomes of NSTEMI admissions. This study also investigates factors associated with mortality in NSTEMI admissions and its correlation with heart catheterization during admission.

Spontaneous coronary artery dissection is a rare cause of unstable angina, myocardial infarction, and sudden cardiac death, particularly among young women and individuals without conventional atherosclerotic risk factors. We present the case of a 43-year-old woman who had spontaneous coronary artery dissection involving the left main with extension to left anterior descending artery and left circumflex artery. She was ultimately managed medically, with a good outcome.

Purpose: Magnetization prepared rapid gradient echo (MPRAGE) is a useful three-dimensional (3D) T1-weighted sequence, but is not a priority in routine brain examinations. We hypothesized that converting 3D MRI localizer (AutoAlign Head) images to MPRAGE-like images with deep learning (DL) would be beneficial for diagnosing and researching dementia and neurodegenerative diseases. We aimed to establish and evaluate a DL-based model for generating MPRAGE-like images from MRI localizers.
