“…Further study also found that the RPADi was closely correlated with the sPAP [77]. However, the reference range of RPADi was significantly different, depending on the echocardiographic views [77,80].…”

“…One canine study suggested that a RPADi <35 is indicative of PH, while values of 28-35, 23-27, and <23 are indicative of mild (30-55 mmHg), moderate (56-79 mm Hg), and severe PH (>79 mm Hg), respectively [80].

“…The 2D-EC evidence of PA/RVOT dilation is the simplest way to detect the existence of PH in dogs with MMVD [35,[74][75][76][77]. Since chronic pressure overload and volume overload in RV can cause RV concentric hypertrophy (thickened RV free wall) and eccentric hypertrophy (RV dilation), respectively, simple 2D measurements of RV free wall thickness and dimension may help to identify dogs with PH [74,78].…”

“…Therefore, MPA/Ao ratio > 1 indicates the PA dilation meaning the existence of PH, unless there is RVOT obstruction. Many studies revealed the dilation of MPA in dogs with PH [35,[74][75][76][77].…”

“…Right pulmonary artery distensibility index (RPADi) is the difference in diameters of the right pulmonary artery (RPA) at systole and diastole obtained from either M-mode right parasternal short-axis ( Figure 11A and B) or long-axis four-chamber view ( Figure 12A) of PA [77,80]. One canine study suggested that a RPADi <35 is indicative of PH, while values of 28-35, 23-27, and <23 are indicative of mild (30-55 mmHg), moderate (56-79 mm Hg), and severe PH (>79 mm Hg), respectively [80].…”

Myxomatous mitral valve disease (MMVD) is the most common heart disease in dogs and has many similarities to human mitral valve prolapse (MVP). Transthoracic echocardiography is a non-invasive method for making a diagnosis and predicting the progression of heart failure (HF) in dogs and humans with mitral regurgitation (MR). It enables clinicians to detect the mitral valve (MV) lesions, to evaluate MR severity, and to assess its impact on cardiac remodeling, myocardial function, left ventricular (LV) filling pressures, as well as pulmonary arterial pressure. Furthermore, advanced ultrasound technologies such as tissue Doppler imaging (TDI), strain and strain rate imaging, and two-dimensional (2D) speckle tracking echocardiography (STE) provide a better assessment of global and regional myocardial function. Although the severity of MR and HF in dogs with MMVD is being evaluated as similar to human cardiology, the veterinary cardiologists are more focused on the severity of cardiac remodeling and cardiac dysfunction caused by MR, because surgical restoration of defected mitral apparatus is rarely done in dogs. The chapter will review conventional echocardiographic features of MMVD in dogs to provide a better understanding of the similarities and discrepancies between canine MMVD and human MVP to veterinary and human cardiologists and researchers.
