This chapter explores atrial septal defects (ASDs), including ostium secundum ASD, ostium primum ASD, sinus venosus ASD, coronary sinus defect, and patent foramen ovale. Ventricular septal defects (VSDs) are also discussed, including definition and incidence, cardiac associations, presentation, physical signs, investigation, and management. A further section explores atrioventricular septal defects (AVSDs), including associations, incidence and recurrence, clinical presentation, investigation, surgical management, and late complications after repair AVSD repair.

It is now well recognized that patients fulfilling the diagnostic criterions for the group of hearts usually described as atrioventricular canal malformations, or atrioventricular septal defects, can present with shunting at atrial level, at both atrial and ventricular levels, and on occasion, with shunting only at ventricular level.1,2It is also well recognized that, in most instances, the patients with shunting exclusively at atrial level have separate atrioventricular valvar orifices for the right and left ventricles, this arrangement often described as the “ostium primum” variant of atrial septal defect.3Morphological and echocardiographic studies, however, have shown that, in this variant presumed to represent deficient atrial septation, it is the atrioventricular septal structures, rather than the atrial septum, which are deficient, the phenotypic feature being the presence of a common atrioventricular junction.4,5In this review, we will show how, using modern day echocardiographic techniques, particularly the newly developed potential for three-dimensional display, it is an easy matter to identify the presence or absence of the common atrioventricular junction, and then to demonstrate the various relationships between the valvar leaflets, the septal structures, and the common junction itself which determine the options for clinical presentation within the group.

: Infective Endocarditis (IE), a known complication of hemodialysis (HD), has recently been categorized as Healthcare-Associated Infective Endocarditis (HAIE). Single pathogen bacteremia is common, polymicrobial endocardial infection is rare in this cohort of the patients. We report a case of endocarditis caused by Enterococcus faecalis (E. faecalis) and Burkholderia cepacia (B. cepacia), a first ever reported combination of a usual and an unusual organism, respectively, in a patient on HD. Clinical presentation of the patient, its complicated course ,medical and surgical management ,along with microbial and echocardiographic findings is presented herein. The authors believe that presentation of this case of HAIE may benefit and contribute positively to cardiac science owing to the rare encounter of this organism as a pathogen in infective endocarditis and the difficulties in treating it.

Oesophageal disorders are relatively uncommon in large animals. Oesophageal obstruction is the most frequently encountered clinical presentation in bovine and it may be intraluminal or extra luminal (Haven, 1990). Intraluminal obstruction or “choke” is the most common abnormality that usually occurs when foreign objects, large feedstuff, medicated boluses, trichobezoars, or oesophageal granuloma lodge in the lumen of the oesophagus. Oesophageal obstructions in bovine commonly occur at the pharynx, the cranial aspect of the cervical oesophagus, the thoracic inlet, or the base of the heart (Choudhary et al., 2010). Diagnosis of such problem depends on the history of eating particular foodstuff and clinical signs as bloat, tenesmus, retching, and salivation
