Special Issue Information

Dear Colleagues,

Veterinary cardiology has become a permanent fixture, both in the way of services provided by general practitioners, and also in specialized centers, which are being established in growing numbers around the world. Acquired heart disease, which develops and progresses with age, accounts for the vast majority of cardiac cases. They are also the subject of greatest interest to researchers, due to the prevalence and difficulties encountered during their treatment. Among them, the most common are myxomatous mitral valve disease in small-breed dogs, dilated cardiomyopathy in large-breed dogs and hypertrophic cardiomyopathy in cats. In contrast, congenital heart defects, which are significantly less common, can pose considerable diagnostic challenges and be cumbersome in terms of selecting the optimal treatment protocol. Due to the rapidly developing branch of interventional cardiology, including minimally invasive procedures, a growing number of defects, such as patent ductus arteriosus, pulmonic stenosis, atrial septal defects or ventricular septal defects, can be successfully addressed by surgical methods. In many cases, such treatment results in a complete recovery, which positively affects the rest of the animal's life. With the use of advanced diagnostics, such as 3D and 4D transesophageal echocardiography, cardiac magnetic resonance imaging (MRI), and cardiac computed tomography (CT), the characteristics of acquired and congenital defects and their complexities can be assessed very accurately, favoring the selection of optimal treatment methods, as well as allowing the determination of possible strategies for surgery. Thanks to this comprehensive approach, veterinary cardiology services in many countries around the world have achieved incredibly high standards of care.

In this issue, we would like to focus on original research data and case reports on acquired and congenital heart defects in dogs and cats. We intend to pay special attention to complex diagnostic approaches and possible treatment options with both conventional and surgical methods, including new methods or surgical tools. Papers dealing with retrospective data as well as reviews broadly commenting on recent reports in the field of congenital malformations will also be valuable. 

We look forward to receiving your contributions.

Congenital heart defects (CHDs) in dogs and cats represent a definite minority of cardiac patients. One of the most commonly diagnosed is ventricular septal defects (VSDs). These are associated with abnormal ventricular septation during the prenatal period; however, the mutations of the genes responsible for this phenomenon are not fully understood. VSDs pose a significant diagnostic challenge due to the multitude of locations in the ventricular septum where they are likely to occur. Therefore, there are many phenotypes of the defect causing many problems in terms of a common nomenclature. Among the various classifications, the latest terminology issued by The International Society for Nomenclature of Paediatric and Congenital Heart Disease (ISNPCHD) considers both electrical conduction pathways and adjacent structures to standardize nomenclature. Further, defects located at different sites can alter both prognosis and subsequent management for the patient; thus, taking accurate measurements is crucial. Among these, the Qp:Qs and VSD:Ao ratios, the direction of blood flow through the defect, its location, the diameter and maximum flow velocity, and the pressure difference between the RV and LV are indicated. Emerging technologies such as 3D echocardiography and cardiac magnetic resonance may provide additional diagnostic value. Altogether, along with clinical symptoms, we should determine further management, involving the monitoring of the patient, the implementation of pharmacological treatment, or referral for surgical closure of the VSD. This review summarizes current knowledge on VSD, where the pathogenesis of the condition, diagnosis, and management, including conventional and surgical methods as well as long-term follow-up, are described, providing a complete overview of the issue.
