A 74-year-old man after multiple mitral valve surgeries underwent catheter ablation of a bi-atrial tachycardia (BiAT). Ultra-high resolution activation mapping exhibited a reentrant circuit propagating around the inferior to anterior mitral annulus and ...

Transseptal access for atrial fibrillation ablation can be challenging in the presence of iatrogenically modified interatrial septum. We report the first described transseptal left atrial access for atrial fibrillation ablation in the presence of an ...

Is an interatrial communication the same as an atrial septal defect?
It is, perhaps, unfortunate that those using Anglo-saxon tongues, as opposed to romantic languages such as French, Spanish, Italian, or Portuguese, should describe holes permitting shunting between the atrial chambers as septal defects rather than ...

An Unusual Complication of Transseptal Puncture
The interatrial septum is a structure with complex embryological development. The true atrial septum is a circumscribed structure, and transgression outside of this area during transseptal puncture may result in entry into the extracardiac space or aorta

Twisted atrioventricular connections in double inlet right ventricle: evaluation by magnetic resonance imaging [PDF]
Twisted atrioventricular connections occur almost exclusively in the hearts with biventricular atrioventricular connections. Only one example of double inlet left ventricle has been illustrated in which the axes of the two atrioventricular valves crossed

Changes in left atrial deformation in hypertrophic cardiomyopathy: Evaluation by vector velocity imaging. [PDF]
OBJECTIVES: Hypertrophic cardiomyopathy (HCM) represents a generalized myopathic process affecting both ventricular and atrial myocardium. We assessed the global and regional left atrial (LA) function and its relation to left ventricular (LV) mechanics ...

Identification and Morphogenesis of Vestibular Atrial Septal Defects
Background: The vestibular atrial septal defect is an interatrial communication located in the antero-inferior portion of the atrial septum. Reflecting either inadequate muscularization of the vestibular spine and mesenchymal cap during development, or ...

Interatrial septum as a possible source of thromboembolic events
The prompt identification of the type and source of stroke is critical for clinical management, prevention, and treatment. Approximately 25% of ischemic strokes are from the cardioembolic source, and 15–40% of all ischemic strokes are cryptogenic (where ...

Role of cardiac resynchronization therapy in the development of new-onset atrial fibrillation: A single-center prospective study. [PDF]
Albeit several studies examined the association between cardiac resynchronization therapy (CRT) and atrial fibrillation (AF) in heart failure (HF), results are still unclear and quite conflicting.

What role does the right side of the heart play in circulation? [PDF]
Right ventricular failure (RVF) is an underestimated problem in intensive care. This review explores the physiology and pathophysiology of right ventricular function and the pulmonary circulation.
