Introduction And Importance: Coronary-cameral fistulas (CCFs) are the anomalous connection between a coronary artery (CA) and a great vessel or cardiac chamber. About 90Â % of CA fistulas are congenital and are related to persistent sinusoids during the embryonic period. Most fistulas originate from the right and left anterior descending CAs. The circumflex CA is rarely involved.
Case Presentation: A 20-year-old male was referred to a tertiary children's heart hospital center due to retrosternal chest pain (CP) and dyspnea on exertion (functional class Ш). The transthoracic echocardiography (TTE) was done, and it demonstrated a dilated left coronary artery (LCA) (size:5 mm) with a large aneurysm (2 cm) and a small orifice to the right ventricle (RV) body. Then, cardiac angiography was done, and dilated LCA and CCF were demonstrated in the RV. Subsequently, the aneurysm was occluded by eight coils.
Clinical Discussion: CCAs can be treated by transcatheter approach or surgical repair. In the presented case, we planned to treat this condition through Cardiac Angiography. Cardiac Angiography was done, and eight coils occluded the aneurysm. The day after the angiography, the symptoms were completely resolved, and the patient didn't complain of CP and dyspnea.
Conclusion: CCFs represent an uncommon cardiac anomaly with diverse anatomical variations and clinical manifestations. Coronary angiography (CAG) is the most accurate diagnostic test to determine fistula anatomy and possible therapeutic options. Small symptomatic and large fistulas, regardless of symptoms, necessitate intervention through either a transcatheter approach or surgical repair.

Background: Charcot-Marie-Tooth is the most common inherited neuromuscular disorder. Rarely, it can be associated with heart failure and various arrhythmic disturbances. This case illustrates the challenges of making decisions to prevent sudden cardiac death in a patient with Charcot-Marie-Tooth disease.

Women with breast implants have higher adjusted abnormal cardiac testing and coronary angiography but lower coronary intervention.
Am J Med
December 2024
University of Arizona, College of Medicine, Phoenix.
Background: Breast implants interfere with myocardial perfusion imaging (SPECT) and echocardiographic windows leading to increased false positive results. To validate this concept, we hypothesized that patients with breast implants should have higher positive cardiac testing and coronary angiogram with lower percutaneous coronary intervention (PCI) rates compared to women without a breast implant.
Methods: Using ICD 10 codes for breast implants, abnormal results of cardiac functional study, coronary angiogram, and percutaneous coronary interventions, we evaluated any association between these parameters in adult women with breast implants utilizing the National Inpatient Sample (NIS) database.
Iron levels and vulnerable coronary atherosclerotic plaques.
Kardiol Pol
January 2025
Department of Coronary and Structural Heart Diseases, National Institute of Cardiology, Warszawa, Poland.
Background: Preliminary research indicates that higher iron levels are associated with worse outcomes in patients with coronary artery disease.
Aims: The study aimed to investigate the relationship between iron levels and the type and composition of coronary plaques.
Methods: In patients with ≥1 coronary stenosis ≥50% on computed tomography angiography, iron levels, presence of high-risk plaque features, such as low-attenuation plaque (LAP), napkin-ring sign, positive remodeling, and spotty calcium, as well as type and plaque composition (calcified/fibrous/fibro-fatty/necrotic core) were evaluated.

Unlabelled: Introduction y objectives: Tako-tsubo syndrome (TTS) is a cardiac condition that mimics acute coronary syndrome, characterized by transient left ventricular dysfunction in the absence of culprit coronary artery stenosis. Although its etiology remains unknown, reversible microvascular dysfunction secondary to an adrenergic surge is thought to play a role. Treatment is empirical, although most patients receive beta-blockers (BB) in clinical practice.
