MMVD: Staging the Murmur Before It Stages You

Dr. Rosemary Stolzer-Bolton, DVM, DVMCaninePre-RACE approval · 0.5–3 CE creditsFree Preview

Myxomatous mitral valve disease is the most common acquired cardiac disease in dogs — and the line between watchful waiting and a 15-month head start runs through a single echocardiographic threshold. Follow Bella, a 7-year-old Cavalier King Charles Spaniel, from a routine wellness murmur through ACVIM staging, pimobendan initiation, and a complete long-term management plan grounded in EPIC trial evidence. Earn RACE CE credit (approval pending; hours assigned at approval).

Learning Objectives

  • 1Distinguish ACVIM Stages B1 and B2 using echocardiographic thresholds (LA:Ao ≥1.6, LVIDD-N ≥1.7) and VHS criteria, and identify Stage B2 as the evidence-based treatment threshold
  • 2Explain the dual mechanism of pimobendan as a calcium sensitizer and phosphodiesterase III inhibitor, and apply EPIC trial data to justify initiation at Stage B2 without concurrent diuretics or ACE inhibitors
  • 3Construct the multimodal Stage C treatment protocol (pimobendan, furosemide 2 mg/kg q12h, ACE inhibitor, spironolactone) and implement appropriate renal and electrolyte monitoring after each drug class
  • 4Evaluate Stage D escalation options including torasemide conversion, hydralazine or amlodipine for afterload reduction, digoxin for atrial fibrillation rate control, and sildenafil for secondary pulmonary hypertension
  • 5Analyze the evidence base for integrative cardiac supplements (omega-3 fatty acids, CoQ10, taurine) and implement a resting respiratory rate home monitoring protocol that detects decompensation before clinical crisis
