Plain-English summary
Eleven dogs with heart problems caused by myxomatous mitral valve disease developed a serious condition called left atrial rupture. Most of these dogs were older, averaging around 11.6 years, and while 10 survived the first day after diagnosis, only 5 were still alive several months later. Dogs without a history of congestive heart failure (CHF) lived longer, averaging about 345 days, compared to those with CHF, who averaged 160 days. Overall, the outcome for these dogs was better than expected, especially for those without previous heart issues.

Abstract
The purpose of this retrospective study was to evaluate the long-term outcome in dogs with left atrial rupture secondary to myxomatous mitral valve disease. Eleven client-owned dogs met the inclusion criteria for the study. Median age was 11.6 yr (range, 8.3-17.8 yr), and median weight was 5.8 kg (range, 3.8-15.2 kg). Of the 11 dogs, 10 survived the initial 24 hr after diagnosis and 5 of the dogs were still alive at the conclusion of data collection. The median survival of all dogs was 203 days. Dogs with no previous history of congestive heart failure (CHF) at the time of diagnosis had a significantly longer median survival time (345 days) compared with dogs with a previous history of CHF (160 days, P = 0.0038). Outcome of dogs with myxomatous mitral valve disease presenting with left atria rupture was more favorable than previously reported, and dogs without previous CHF survived the longest.
