Key result
Balloon valvuloplasty for severe valvular pulmonic stenosis in a dog was complicated by cardiac arrest and pericardial tamponade, which was successfully treated with pericardiocentesis.
Why the study?
The report was intended to raise awareness of pericardial tamponade as a potential complication during balloon valvuloplasty for pulmonic stenosis and describe its clinical signs and treatment.
Case Report (n=1)
Pericardial tamponade is a possible life-threatening complication during balloon pulmonary valvuloplasty in dogs that can be successfully managed with prompt pericardiocentesis.
Prompts caution with guidewire manipulation in balloon valvuloplasty for pulmonic stenosis; leaves open optimal management of intraprocedural arrest.
A 4‐month‐old entire male Coton de Tulear dog was referred for balloon valvuloplasty for treatment of severe valvular pulmonic stenosis. During the procedure, when attempting to pass the guide wire into the ventricle, the dog developed cardiac arrest. After initial resuscitation with chest compressions, manual ventilation, adrenaline and intravenous fluids, focused cardiac ultrasound revealed pericardial effusion and cardiac tamponade. Pericardiocentesis resolved the haemodynamic emergency. This case report should raise awareness of pericardial tamponade as a possible complication during pulmonic stenosis balloon valvuloplasty. It describes the clinical signs observed during anaesthesia as well as how to treat it with a positive outcome.

Wieser et al. (2021) conducted a case report in Severe valvular pulmonic stenosis (n=1). Balloon valvuloplasty was evaluated on Pericardial tamponade and cardiac arrest. Balloon valvuloplasty for severe valvular pulmonic stenosis in a dog was complicated by cardiac arrest and pericardial tamponade, which was successfully treated with pericardiocentesis.
