In the last decade, there has been increasing evidence that comprehensive evaluation of the left atrium is of utmost importance. Numerous studies have clearly demonstrated the prognostic value of left atrial volume for long-term outcome. Furthermore, advances in catheter ablation procedures used for the treatment of drug-refractory atrial fibrillation require the need for detailed knowledge of left atrial and pulmonary venous morphology as well of atrial wall characteristics. This review article discusses the role of cardiac magnetic resonance and computed tomography in assessment of left atrial size, its normal and abnormal morphology, and function. Special interest is paid to the utility of these rapidly involving noninvasive imaging methods before and after atrial fibrillation ablation. [ABSTRACT FROM AUTHOR]

Coronary artery anomalies represent a diverse group of congenital disorders characterized by abnormalities of coronary arteries anatomy. We describe an extremely rare case of giant torturous left circumflex artery draining to the right atrium manifesting by palpitations and atrial fibrillation. [ABSTRACT FROM AUTHOR]

We present images of a papillary fibroelastoma on a pulmonary valve – echocardiography, intraoperative images, macroscopic and microscopic images of the tumor in this uncommon location. Image 1 • Papillary fibroelastomas are rare benign tumors located most commonly on the aortic or mitral valves. • Their surface is furrowed by avascular fronds resembling a sea anemone or a pom-pom. • Avascular fronds are composed predominantly of fibrous tissue and elastic fibers covered by bland endothelium. • Some papillary fibroelastomas can be excised by a valve-sparing approach.
