1. Cone reconstruction for severe tricuspid valve dysplasia in a dog.
PMID:期刊:日期:2026-09-01Tricuspid valve dysplasia (TVD) is a congenital cardiac malformation in dogs characterized by abnormal tricuspid valve morphology, leaflet tethering, impaired leaflet coaptation, and right atrial and ventricular remodelling. This report describes cone reconstruction for severe TVD in a dog. A three-year-and-10-month-old female Labrador retriever presented with a grade IV/VI systolic murmur and exercise intolerance. Echocardiography revealed severe tricuspid regurgitation, a right atrial-to-left atrial ratio of 1.57, malformed and tethered tricuspid valve leaflets, impaired leaflet coaptation, and marked right-sided cardiac enlargement, consistent with severe TVD. Surgery involved tricuspid valve leaflet mobilization, delamination of adherent leaflet tissue and abnormal subvalvular attachments, annular reduction, and reconstruction of the available leaflet tissue into a cone-like valve with leaflet rotation and reattachment. A small, thin, dysplastic portion of the right ventricular free wall was also excluded from the functional right ventricular cavity by longitudinal plication. The dog was discharged on postoperative day seven without other major complications. On postoperative day 294, echocardiography showed a reduction in the colour Doppler tricuspid regurgitant jet, a decrease in the right atrial-to-left atrial ratio to 0.50, and a reduction in right atrial size. Exercise intolerance resolved, although a grade III/VI systolic murmur persisted. Cone reconstruction, adapted from the technique used in human patients with Ebstein's anomaly, may improve tricuspid valve function and clinical signs in selected dogs with severe TVD. However, its indications, reproducibility, and long-term durability in dogs remain unestablished. Further studies are needed to evaluate patient selection, long-term benefits, and potential complications.

3. Use of a novel integrated dilator-needle system for trans-septal puncture in three dogs undergoing left atrial decompression.
PMID:期刊:日期:2026-08-22Left atrial decompression (LADEC) is an emerging palliative intervention for dogs with advanced left-sided congestive heart failure. Trans-septal puncture is a critical step of this procedure and is traditionally performed using Brockenbrough-style needles with multiple device exchanges. A novel integrated dilator-needle system (FlexCath Cross™, Medtronic) has been developed in human cardiology to allow a zero-exchange approach to trans-septal puncture; however, its use in veterinary patients has not previously been described. This report describes the technical feasibility of using this integrated system for trans-septal access in three dogs undergoing LADEC for congestive heart failure secondary to myxomatous mitral valve disease. In three cases, trans-septal access was successfully achieved using the integrated dilator-needle system, allowing completion of the planned LADEC procedure. No major device-related complications were observed. These cases demonstrate the feasibility of this alternative trans-septal access technique in selected canine patients.

4. Evaluation of the mitral-aortic velocity time integral ratio for severity assessment in dogs with myxomatous mitral valve disease.
PMID:期刊:日期:2026-08-22In dogs, myxomatous mitral valve disease is the most commonly acquired cardiac disorder. Quantitative assessment of mitral regurgitation (MR), particularly regurgitant volume normalized to body weight (RVol/kg), remains challenging. A Doppler-derived mitral-to-aortic velocity time integral (VTI) ratio (calculated as mitral inflow VTI) divided by left ventricular outflow tract VTI]) has been proposed in humans to stratify MR severity. This study evaluated its association with MR severity, American College of Veterinary Internal Medicine stage, and congestive heart failure (CHF). We evaluated 167 dogs with myxomatous mitral valve disease and 21 controls. Echocardiography included mitral inflow VTI, left ventricular outflow tract VTI, and RVol/kg. Repeatability was assessed using intraclass correlation coefficients. Receiver operating characteristic analysis was used to evaluate performance for detecting CHF and severe MR defined by a regurgitant fraction (RF) ≥50%. The mitral-to-aortic VTI ratio increased with stage (P<0.001) and correlated with RVol/kg and RF (r=0.75 each; P<0.001), with high repeatability (intraclass correlation coefficient >0.90). Multivariable regression identified early diastolic transmitral velocity (E), left atrium-to-aorta ratio, and RVol/kg as independent determinants of the mitral-to-aortic VTI ratio. Logistic regression to detect CHF (current and past) showed the association between the mitral-to-aortic VTI ratio and CHF. In the receiver operating characteristic curve analysis, the mitral-to-aortic VTI ratio showed the highest accuracy for identifying an RF ≥ 50% (area under the curve=0.89). Few dogs were in stage C/D. The mitral-to-aortic VTI ratio is a reproducible Doppler index associated with MR severity and American College of Veterinary Internal Medicine stage and may help indicate clinically relevant RF thresholds.

5. Predominant mitral valve morphology in dogs at different stages of myxomatous mitral valve disease: toward a standardized nomenclature.
PMID:期刊:日期:2026-08-20Myxomatous mitral valve disease (MMVD) is the most common heart disease in dogs. Echocardiographic markers of cardiac remodeling are used to assess disease severity, but morphological features of the mitral valve are not systematically considered. Conversely, standardized morphological classification schemes are established in human cardiology and are integral to prognosis and therapeutic planning. Our objective was to adapt and apply a mitral valve morphological classification scheme to canine MMVD across various stages. A total of 1108 dogs weighing 1-15 kg with an echocardiographic diagnosis of MMVD (American College of Veterinary Internal Medicine stage B1 = 595; B2 = 314; C/D = 199) were included in the study. Echocardiographic studies were retrospectively reviewed. Leaflet involvement was identified using right parasternal and left apical views and classified as billow, prolapse, isolated flail, or prolapse with flail based on established morphologic descriptions by Barlow and principles of leaflet motion derived from the Carpentier classification. Anterior leaflet involvement predominated all stages, though bileaflet involvement increased in stage C/D. Billow morphology decreased significantly across stages (B1: 79%; B2: 17%; C/D: 5%; P<0.001). Prolapse and isolated flail were significantly more common in stages B2 and C/D than in stage B1 (P<0.001). Prolapse with flail increased progressively from stage B1 (5%) to B2 (25%) to C/D (56%) (P<0.001). This was a retrospective, single-center study with no longitudinal follow-up. Advanced imaging modalities were not evaluated. Mitral valve morphology in dogs with MMVD varies systematically with disease stage, and adoption of a standardized morphological classification scheme will align veterinary cardiology with established human frameworks.

6. Multicenter transvenous pacemaker implantation in 595 dogs: complications and survival rates.
PMID:期刊:日期:2026-08-10Transvenous pacemakers are routinely used for pathologic bradyarrhythmias including third-degree atrioventricular block (3AVB), sick sinus syndrome (SSS), high-grade second-degree atrioventricular block (2AVB), and atrial standstill (AS). This study reports the multi-institutional complications and survival rates in a large cohort of dogs. A retrospective analysis of outcomes and complications in dogs that underwent transvenous pacemaker implantation between January 2000 and December 2016 at four academic institutions was conducted. In total, 595 dogs were identified (221 males and 374 females) with a median age of 10.1 years (range: 0.3-17.0 years). Presenting arrhythmias included 3AVB (54.5%), SSS (24.4%), high-grade 2AVB (16.1%), and AS (4.0%). Major complications occurred in 17.5% (104/595) of cases including lead dislodgement (n = 39), infection (n = 24), thrombus formation (n = 19), ventricular fibrillation (n = 8), cardiac arrest (n = 6), cardiac perforation (n = 5), and iatrogenic tricuspid stenosis (n = 3). Ventricular lead dislodgement in AS (20%) occurred more frequently than SSS (1.4%; P=0.002), and 80% of the ventricular leads that dislodged in dogs with AS were passive leads. Procedural mortality rate was 0.8% (5/595). Median survival time was 2.8 years (2AVB, 2.9 years; 3AVB, 2.9 years; AS, 3.3 years; SSS, 2.5 years). Cardiac mortality occurred in 60.0% of AS cases compared to 2AVB (25.0%), 3AVB (21.9%), and SSS (16.9%). Limitations of this study included the retrospective nature of the project with some loss to follow-up. Pacemakers have a low procedural mortality rate, and overall, complications were minimal. Type of lead and underlying disease process may impact the risk of lead dislodgement. Dogs with AS are more likely to die from cardiac-related disease.

7. Clinical utility of shear wave speed and dispersion slope measured by shear wave elastography for the assessment of hepatic congestion in dogs with cardiac disease.
PMID:期刊:日期:2026-08-10Right-sided heart failure (RHF) elevates central venous pressure, causing hepatic congestion. Two-dimensional shear wave elastography (2D-SWE) measures shear wave speed (SWS) and dispersion slope (DS), reflecting tissue viscoelasticity and viscosity. The aim was to investigate associations between hepatic SWS and DS and RHF in dogs and evaluate clinical utility. One hundred client-owned dogs with cardiac disease were prospectively classified into RHF (n = 27) and non-RHF (n = 73) groups based on ascites. Hepatic SWS and DS were measured using 2D-SWE. Congestion and cardiac function were assessed via caudal vena cava short-to-long diameter ratio (CVC SD/LD), right atrial area index (RAA index) and left ventricular outflow tract velocity-time integral (LVOT-VTI). Associations between elastography and echocardiographic variables were analysed, and diagnostic performance for RHF was evaluated. Both SWS and DS were significantly higher in RHF dogs (SWS: 1.79 [1.63-2.38]; DS: 16.40 [15.55-19.83]) than non-RHF dogs (SWS: 1.31 [1.25-1.37]; DS: 12.5 [11.0-13.5]; P<0.001) and were moderately correlated with CVC SD/LD, RAA index and LVOT-VTI. Receiver operating characteristic analysis showed DS had the highest area under the curve. Multiple regression analysis indicated SWS was associated with CVC SD/LD and LVOT-VTI, while DS was associated with CVC SD/LD and RAA index. It is a single-centre study without histopathologic confirmation. Hepatic SWS and DS measured are promising non-invasive markers for RHF in dogs. In particular, DS is more specific for hepatic congestion, while SWS reflects both congestion and low cardiac output-related changes.

8. Incidentally diagnosed non-dissecting thoracic aortic aneurysm in a dog with suspected aortic valve abnormality.
PMID:期刊:日期:2026-08-01A thoracic aortic aneurysm (TAA) is a relatively common cardiovascular disorder in humans. However, it is rarely reported in dogs. To date, several reported canine cases are associated with clinical signs and severe complications, such as aortic dissection and rupture. Herein, we report an incidentally diagnosed TAA in an asymptomatic elderly dog with suspected aortic valve abnormality. A 12-year-old spayed female Shiba Inu was referred for the evaluation of anorexia and vomiting. It was subsequently diagnosed with gallbladder mucocele. Thoracic radiography revealed cranial mediastinal widening, and transthoracic echocardiography showed marked dilation of the thoracic aorta distal to the sinus of Valsalva, with a maximal diameter of 30.2 mm. Echocardiographic findings revealed an abnormal aortic valve morphology characterized by asymmetric cusp motion and eccentric systolic opening, accompanied by aortic regurgitation. Severe circumferential dilation of the aortic root, ascending thoracic aorta, and aortic arch, without evidence of dissection or rupture, was confirmed on computed tomography angiography and intra-operative transesophageal echocardiography. Hence, a diagnosis of a non-dissecting fusiform TAA was made. The clinical signs resolved completely after cholecystectomy, and the dog remained clinically stable for >200 days without specific treatment for the aortopathy. This is a rare case of an incidentally diagnosed TAA in a dog with aortic valve abnormality. This case indicates that canine TAA may be under-recognized and emphasizes the importance of advanced imaging modalities for identifying TAA in dogs.

9. Impaired left ventricular systolic function assessed by endocardial global longitudinal strain imaging in cats with restrictive cardiomyopathy.
PMID:期刊:日期:2026-08-01Restrictive cardiomyopathy (RCM), the second most common cardiomyopathy in cats, is known to induce primary diastolic dysfunction. Little is known about systolic function in cats with RCM. The aim of this study was to evaluate systolic function using two-dimensional speckle-tracking echocardiography-derived endocardial global longitudinal strain (GLS) in a population of cats with RCM. Twenty-five adult cats diagnosed with RCM as well as 25 healthy control cats were included in the present study. Left apical two-, three-, and four-chamber views were obtained retrospectively for endocardial GLS analysis derived by two-dimensional speckle tracking. Comparison of cats with RCM with a matched control group was performed. Cats with RCM had significantly larger left ventricular internal diameters in both, systole (P<0.0001) and diastole (P=0.0015), than controls. In systole, cats with RCM had values of 11.05 mm ± 2.24, in contrast to those of 8.48 mm ± 1.35 in healthy controls. In diastole, these values were 16.10 mm (range: 10.50-20.60 mm) in cats with RCM, higher than 14.90 mm (range: 10.00-17.50 mm) in the control group. Global longitudinal strain values were significantly lower in cats diagnosed with RCM than in control cats (P<0.0001), with a mean value of -17.68% ± 4.78 vs. -28.35% ± 3.72, respectively. Limitations mainly comprised the retrospective character of the study, leading to lack of treatment standardization and histopathology, as well as a limited population of felines. Endocardial GLS is reduced in cats with RCM, indicating that cats with RCM not only have a diastolic but also systolic dysfunction.

10. Lipomatous hypertrophy of the interatrial septum in a dog: echocardiographic, gross pathologic, and histologic findings.
PMID:期刊:日期:2026-08-01A 12-year-old, 20-kg, Cocker spaniel was evaluated for the recent onset of marked weakness. Cardiologic assessment revealed myxomatous degeneration of the atrioventricular valves, moderate left atrial dilation, and a sustained narrow QRS complex tachycardia primarily consistent with focal atrial tachycardia. Moreover, two-dimensional imaging of the interatrial septum showed a hyperechoic, multifocal thickening (maximum thickness: 10 mm). Differential diagnoses included neoplastic infiltration, intracardiac thrombosis, and mural endocarditis. Despite prompt hospitalization in the intensive care unit and combination antiarrhythmic therapy, adequate control of the tachyarrhythmia was not achieved, and euthanasia was ultimately elected. Necropsy confirmed myxomatous mitral valve degeneration and excluded cardiac neoplasia, thrombosis, and mural endocarditis. Histologic examination of the interatrial septum revealed abnormal infiltration by mature adipose tissue, causing full-thickness separation and dissociation of septal myofibers. Based on antemortem and postmortem findings, the diagnosis was lipomatous hypertrophy of the interatrial septum, a condition not previously reported in dogs but well recognized in human cardiology.
