Pericardium: hemangiosarcoma

icanis

Introduction

  • May affect right atrium, right atrioventricular junction or right ventricle alone or other sites (spleen, etc).
  • Vascular tumor - often ruptures and bleeds into pericardial space.
  • Sudden build-up of pericardial blood leads to increased pericardial pressure, which compromises atrial and ventricular filling.
  • Signs: collapse, output failure. Ventricular or supraventricular dysrhythmias.

Pathogenesis

Etiology

  • Not known.

Predisposing factors

General
  • Breed.

Pathophysiology

  • Hemangiosarcoma → frequently affects right atrium → pericardial sac → other areas of the heart → pericardial fluid.

Timecourse

  • Apparent acute onset → recurrence of signs common → usually fatal within weeks/months.
