A 2-year-old, neutered male, domestic shorthair cat was presented for investigation of dyspnea and episodic weakness. Clinical and ultrasonographic features were consistent with right ventricular cardiomyopathy. Pathological findings documented Uhl’s anomaly. Although rare, Uhl’s anomaly should be a differential diagnosis for cats with right-sided congestive heart failure. In particular, Uhl’s anomaly could be misdiagnosed as arrhythmogenic right ventricular cardiomyopathy due to the similarity of clinical and echocardiographic findings.

ABSTRACT Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an important cause of sudden death in people and boxer dogs that has recently been described in English bulldogs. The objective of this retrospective study was to describe the clinical characteristics of English bulldogs with presumed ARVC. The medical records were searched for English bulldogs examined between 2001 and 2013 with a clinical diagnosis of ARVC. The average age of the 31 dogs identified was 9.2 ± 1.6 yr (range 7–13 yr). Males were overrepresented by a factor of 2.9 to 1. At initial presentation, 5 dogs had subclinical arrhythmia, 10 dogs had clinical signs attributable to arrhythmia, and 16 dogs had congestive heart failure. Eighteen dogs (58%) had ventricular tachycardia and five (16%) also had supraventricular arrhythmias. Four dogs experienced sudden death, 2 dogs died from congestive heart failure, 11 dogs were euthanized for cardiac causes, and 2 dogs died or were euthanized for noncardiac causes. Kaplan-Meier analysis showed a median survival time of 8.3 mo. This is the first study to describe the clinical characteristics of a population of English bulldogs with presumed ARVC. Further studies are needed to better characterize the clinical features of the disease in this breed.

In Pregnancy

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetic disorder resulting in fibrofatty replacement of the myocardium. Genetic mutations in genes encoding for desmosome proteins result in a ventricular myocardium prone to arrhythmias and heart failure. Although ARVC is known for a few decades, most of the outcomes in pregnancy are reported recently. Pregnancy leads to significant physiological changes with excess mechanical stress on the myocardium. All the retrospective studies suggest that pregnancy is well tolerated in these patients despite the high risk of arrhythmias and heart failure. Our review focuses on the most up-to-date evidence on the management of ARVC patients during the antepartum and postpartum period.

Ventricular Cardiomyopathy

Patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) have arrhythmia-related symptoms or are identified during screening of an affected family. Heart failure symptoms occur late in the disease’s natural history. As strenuous exercise has been associated with disease acceleration and worsening of ventricular arrhythmias, lifestyle modification with restricted athletic activities is recommended upon disease diagnosis or even identification of mutation carrier status. An episode of an haemodynamically unstable, sustained ventricular tachycardia or ventricular fibrillation as well as severe systolic ventricular dysfunction constitute definitive indications for implantable cardioverter defibrillator (ICD) implantation, which should also be considered following tolerated sustained or non-sustained ventricular tachycardia episodes, syncope, or in the presence of moderate ventricular dysfunction. Antiarrhythmic medications are used as an adjunct to device therapy. Catheter ablation is recommended for incessant ventricular tachycardia or frequent appropriate ICD interventions despite maximal pharmacological therapy. Amiodarone alone or in combination with beta blockers is most effective for symptomatic ventricular arrhythmias. Beta blockers are considered for use in all patients with a definite diagnosis but evidence for their prognostic benefit is sparse. Heart failure symptoms are managed using standard protocols and heart transplantation is considered for severe ventricular dysfunction or much less commonly uncontrollable ventricular arrhythmias.
