“…Infestation was associated with fibrinonecrotic to granulomatous, extensive, severe epicarditis and pleuritis, and granulomatous bronchitis. The severity of the fibrinous and granulomatous changes to cardiac and respiratory tissues suggested they may have contributed to the death of this harrier through external compression of the heart and pleural tissue, progressively limiting cardiac filling, decreasing cardiac output (de Wit and Schoemaker 2005), and reducing respiratory function. The aberrant gastrointestinal location of the Cyathostoma species nematodes was likely due to postmortem migration which has been reported in wild birds when there is a delay between death and postmortem investigation (Riper and Riper 1980).…”

“…These unique features of the avian heart enable birds to fly, run, or dive. 1 Birds have relatively larger hearts than mammals, and the heart size of small birds is proportionately greater than that of large birds. The avian heart is divided into 4 complete chambers.…”

The goal of this study was to describe normal electrocardiographic (ECG) patterns and values in conscious helmeted guinea fowl (Numida meleagris). Using 8 clinically healthy birds, 4 males and 4 females, standard bipolar and augmented unipolar limb lead ECGs were recorded. Wave forms were analyzed in all leads at 50 mm/s and at 10 mm = 1 mV to determine PR, QRS, ST, QT durations; the net QRS complex; and P and T amplitudes. The polarity of each wave form was tabulated in all leads. The mean electrical axis (MEA) for the frontal plane was calculated by using leads II and III. The mean (SD) heart rate calculated from the lead II was 338.4 +/- 19.0 beats/min. The P wave was predominantly positive in all leads. The dominant pattern of wave forms of the QRS complexes was RS in leads II, III, and aVF; R in lead I; QR in lead aVR; and qR in lead aVL. The T wave was predominantly positive in leads I, II, III, and aVF. The mean (SD) of the heart MEA was -60.2 degrees +/- 24.0 degrees. The ECG values and patterns tabulated in these clinically normal helmeted guinea fowl should provide a means of comparison to aid in the diagnosis of pathologic abnormalities in this species.

“…Cardiovascular diseases in birds are associated with conditions of improper management of these animals in captivity, along with high-calorie diets (restricted to seeds), absence of exercise, and inadequate confinement spaces, which are conditions that predispose most heart diseases (Wit & Schoemaker, 2005;Pees et al, 2006).…”

Owning wild species as pets is becoming more and more common. Consequently, experience in caring for them has grown, resulting in the diagnosis of numerous diseases. Among these are cardiovascular disorders, especially in parrots. However, the lack of specificity or the absence of clinical signs of these diseases make it difficult to assess cardiovascular issues during the physical examination of birds. This leads to underdiagnosis of these conditions, with the majority being diagnosed post-mortem. This study reports the cardiovascular findings in post-mortem examinations of individuals of the species Amazona aestiva (true parrot) of Centro de Triagem de Animais Silvestres do Rio de Janeiro (CETAS-RJ) and is the first record of myxomatous degeneration of the left atrioventricular valve in this species.
