Anatomical description of malformations of the neck of the left atrial appendage.

The recently-described left atrial appendage (LAA) neck is a truncated cone-shaped structure that connects the LAA orifice to its lobe. It shows malformations in some cases, but their exact description and clinical significance are unknown. Therefore, the aim of this study was to provide a detailed anatomical and morphometric analysis of LAA neck malformations in clinical context.

Definition and anatomical description of the left atrial appendage neck.

The left atrial appendage (LAA) is well known as a source of cardiac thrombus formation. Despite its clinical importance, the LAA neck is still anatomically poorly defined. Therefore, this study aimed to define the LAA neck and determine its morphometric characteristics.

Pulmonary valve morphometry revisited: Clinical implications for valvular and supravalvular interventions.

In this cadaver-based study, we aimed to present a novel approach to pulmonary valve (PV) anatomy, morphometry, and geometry to offer comprehensive information on PV structure. The 182 autopsied human hearts were investigated morphometrically. The largest PV area was seen for the coaptation center plane, followed by basal ring and the tubular plane (626.

Topography of the oblique vein of the left atrium (vein of Marshall).

Background: The oblique vein of the left atrium is of interest for electrophysiologists working in the field of both basic science and clinical practice.

Aims: We aimed to examine the topographic anatomy of the oblique vein and to assess the vein's location and relationships with surrounding cardiac structures.

Methods: A total of 200 autopsied adult human hearts were examined.
