Introduction: Degenerative mitral valve disease (DMVD) is the most common canine heart disease with a high predisposition in Cavalier King Charles Spaniels (CKCSs). Mitral regurgitation related to DMVD can lead to left atrial (LA) dilation, which is associated with survival time. Left-atrial-to-aortic (LA:Ao) ratio assessed by two-dimensional echocardiography is commonly used to evaluate LA size.

Article Synopsis
- This study investigates the agreement in left atrial (LA) volume estimates obtained from two echocardiographic views (right parasternal long axis and left apical four-chamber) in a variety of healthy and diseased dogs.
- Researchers analyzed data from 194 dogs, measuring LA volumes using both views and comparing these with estimates from simple geometric volume formulas (cube and sphere).
- Findings indicate that while the two views yield similar volume estimates, they are not interchangeable due to discrepancies, particularly with varying LA sizes, and that the sphere method provides more accurate volume estimates than the cube method.

Introduction: Compare three methods of obtaining linear left ventricular dimensions within the same Doberman Pinscher (DP).
Animals: One hundred and thirty-nine client-owned DP.
Materials And Methods: Linear left ventricular dimensions were measured using two-dimensional short-axis (Sx-2D), motion-mode short-axis (Sx-MM), and motion-mode long-axis (Lx-MM) methods, then left ventricular volumes were obtained using monoplane Simpson's method of discs (SMOD).
Two-dimensional echocardiographic estimates of left ventricular volumes obtained in different views in dogs provide similar measurements but are not interchangeable.

Introduction: Little information exists regarding the interchangeability of left ventricular volume estimates using a monoplane Simpson's Method of Discs on images obtained from the left apical four-chamber and right parasternal long axis four-chamber views. We examined if volume estimates obtained from these views were interchangeable.
Animals: A total of 224 dogs: 86 healthy, 96 with mitral valve disease, 42 with various cardiac pathologies.
