[Percutaneous closure of a coronary-pulmonary fistula : a case report].

Background: A coronary artery fistula is an abnormal connection between one or more coronary arteries and a cardiac chamber or great vessel, often discovered incidentally through cardiac imaging. Although coronary artery fistulas are typically asymptomatic during the first two decades of life, particularly when small, they can become clinically significant over time.

Case Presentation: We present the case of a 71-year-old female patient with a history of exertional dyspnea.

The POT-PUFF Sign: A New Angiographic Indicator of Stent Malapposition During Proximal Optimization Therapy.

Acute stent malapposition poses a significant risk for adverse cardiac events following percutaneous coronary intervention. Detection of acute stent malapposition traditionally relies on intracoronary imaging techniques, such as intravascular ultrasound and optical coherence tomography, which may be limited in developing countries due to accessibility issues. A new angiographic sign called the has been introduced as a potential alternative for detecting malapposition during coronary bifurcation procedures.

Biventricular arrhythmogenic cardiomyopathy diagnosed in a young patient: A case report with literature review.

Arrhythmogenic cardiomyopathy is a genetic heart muscle disease that typically affects the right ventricle. However, 2 other phenotypes affecting the left ventricle were recently discovered. Here, we report the case of an 18-year-old patient with biventricular arrhythmogenic cardiomyopathy, highlighting the challenges encountered in establishing this diagnosis.
