Periodontal disease is commonly diagnosed in dogs and has been associated with systemic lesions in several organs, however, studies correlating this oral condition with heart disease in the canine species are still scarce in the scientific literature. Thus, the objective of the present study was to evaluate such correlation in adult dogs, through serial echocardiographic exams and, nonetheless, to analyze the influence of dental treatment on cardiac function. For this, 60 dogs were used, distributed in two groups, the control (CG, n = 30: presence of periodontal disease, not submitted to oral treatment) and the treated (GT, n = 30: presence of periodontal disease and submitted to oral treatment). The animals of the CG were paired with those of the GT in terms of race, weight, age and degree of periodontal disease. Baseline echocardiographic examinations (D0) of the CG were performed and after 30 days (D30). In GT, examinations were also performed at D0 and D30, however, they were submitted to periodontal treatment after baseline measurements. The echocardiographic exams were performed at the Veterinary Cardiology Laboratory of the Veterinary Hospital of the University of Franca, to record and analyze the interventricular septum in diastole (SIVd), interventricular septum in systole (SIVs), diameter of the left ventricle in diastole (DVEd), left ventricular diameter in systole (EVDs), left ventricular free wall in diastole (PVEd) left ventricular free wall in systole (PVEs) shortening fraction of left ventricle (FS), final diastolic volume (VDF), final stroke volume (VSF), ejection fraction (EF), maximum pulmonary artery pressure gradient (max. GP AP) and left atrial and aortic artery diameter ratio (EA-AO). The results of the CG were statistically compared with those of the GT by means of simple analysis of variance (ANOVA). The data obtained regarding the SIVs, DVEd and PVEs parameters of the GT dogs at D30 showed a statistically significant decrease (p<0.05) when compared to the D30 of the CG. Thus, given the established methodology and the results found, it is possible to infer that periodontal treatment may benefit some cardiac parameters of adult dogs, improving their quality of life and survival.

Left Ventricular Free Wall

Subacute cardiac rupture after myocardial infarction carries a high mortality. This article describes 4 cases—3 with rupture of the left ventricle and 1 with a combined rupture of the left ventricle and interventricular septum (double rupture). All patients were successfully operated; however, the patient with the double rupture died of a massive cerebrovascular accident on the 8th postoperative day. The importance of early diagnosis and prompt surgical intervention is discussed, along with a review of the literature.

To determine the effects of aging on myocyte cell death, Fischer 344 rats at 3, 7, 12, 16, and 24 mo of age were injected with myosin monoclonal antibody for the localization and quantification of necrotic myocyte cell death in the left ventricle, interventricular septum, and right ventricle. Conversely, the presence of DNA strand breaks in myocyte nuclei, indicative of programmed cell death, was evaluated by the terminal deoxynucleotidyl transferase assay and confirmed by DNA laddering. Myocyte necrosis, which involved nearly 1,000 myocytes in the left ventricular free wall at 3 mo, progressively increased with aging, reaching a value of 13,600 myocytes at 24 mo. Corre- sponding values in the interventricular septum were 300 and 9,400 myocytes. In the right ventricle, there were 270 necrotic myocytes at 3 mo and 9,000 at 24 mo. Programmed myocyte cell death was restricted to the left ventricular free wall and included 140 cells at 3 mo. This form of myocyte cell death increased at the subsequent age intervals, resulting in the involvement of 874 cells at 24 mo. The combination of necrosis and apoptosis in the left ventricular free wall was associated with 1,150 cells dying at 3 mo and 14,500 at 24 mo. In conclusion, myocyte cell death, apoptotic and necrotic in nature, constitutes an important determinant of the aging process, possibly mediating the occurrence of ventricular dysfunction and failure in the old heart.

Free Wall Rupture

ABSTRACT Unloading of the left ventricle (LV) is essential for the treatment of LV free-wall rupture (LVFWR), and it is well-known that the LV can be optimally unloaded with the Impella system. However, there has been no report on applying the Impella system for the treatment of LVFWR. Here, we report a patient with FWR after massive myocardial infarction who was successfully treated with non-suture repair via median sternotomy and implantation of Impella CP (Abiomed, Danvers, MA).

First Choice

Pseudoaneurysm of the left ventricle is rare and may occur as a result of transmural myocardial infarction. The course of rupture after acute myocardial infarction varies from a catastrophic event, with an acute tear leading to immediate death (acute rupture), or slow and incomplete tear leading to a late rupture (subacute rupture). Incomplete rupture may occur when the thrombus and haematoma together with the pericardium seal the rupture of the left ventricle and may develop into a pseudoaneurysm. Early diagnosis and treatment is essential in this condition. Two-dimensional color Doppler echocardiography is the first-choice method for most patients with suspected left ventricular pseudoaneurysm (LVP) and suggests left ventricular rupture in 85% to 90% of patients. We report the case of an 87-year-old woman presenting with symptoms and findings of myocardial infarction and left ventricular free wall rupture with a pseudoaneurysm formation diagnosed by echocardiography and confirmed on CT, MRI, and NM. She received only intense medical treatment, because she refused surgery with a favorable outcome. After 24-month followup, she is in NYHA functional class II. The survival of this patient is due to the contained pseudoaneurysm by dense pericardial adhesions, related to her previous coronary bypass surgery.

ABSTRACT This study aimed to evaluate the impact of minimally invasive partial pericardiotomy on echocardiographic variables of morphometry and function in healthy horses. Minimally invasive pericardiotomy was performed in six healthy horses. Echocardiographic evaluation was executed in different moments: prior to the surgical procedure (M0); 24 hours post procedure (M1); 72 hours post procedure (M2) and 28 days post procedure (M3). The following variables were measured: Right ventricular internal diameter in diastole and systole (RVd and RVs), interventricular septum thickness in diastole and systole (IVSd and IVSs), left ventricular internal diameter in diastole and systole (LVd and LVs), left ventricular free wall thickness in diastole and systole (LVFWd and LVFWs), aortic root diameter (Ao) and left atrial diameter (LA). From this data, the following variables were calculated: fractional shortening (FS%), fractional thickening of the interventricular septum (IVS%), fractional thickening of the left ventricular free wall (LVFW%) and the relationship between left atrial and aortic diameters (LA/Ao). After 28 days, a new thoracoscopy was performed for inspection of the thoracic cavity. In M1 and M2 ECO evaluations, a statistically significant change in LVFW and a decrease in RVd, LVd, LVFWs, LA, LVs, FS% and IVS was documented. Pericardiotomy is a promising technique in horses, with minor postoperative complication. The variations in the echocardiographic parameters were transient and did not cause hemodynamic damage to the animals.
