Intervention of Atrial Septal Defect Embolization Using Three-Dimensional Transesophageal Echocardiography-Guided Thoracotomy in a Yorkshire Terrier

Atrial septal defect (ASD) is a relatively rare congenital heart disease in dogs. A radical treatment is defect closure under open heart or occlusion by intervention. Small dogs face challenges with either treatment. This case was an 8-month-old female Yorkshire Terrier, weighing 2.4 kg. She suffered from dyspnea due to deterioration of circulatory dynamics caused by ASD. An Amplatzer was positioned under thoracotomy, guided by three-dimensional transesophageal echocardiography. Postoperative recovery was quick and uneventful. Clinical symptoms disappeared and circulatory dynamics were stable after growth. This method is considered to be a useful treatment option for small dogs with ASD.

Bir Yorkshire Terrier’de Üç Boyutlu Transözofageal Ekokardiyografi Rehberli Torakotomi İle Atriyal Septal Defekt Embolizasyonuna Müdahale

Atriyal septal defekt (ASD) köpeklerde nispeten seyrek görülen bir doğmasal kalp hastalığıdır. Radikal tedavi, açık kalp altında defektin kapatılması veya girişimsel bir müdahale ile tıkanmasıdır. Küçük köpeklerde her iki tedavide de zorluklarla karşılaşılır. Bu olgu, 2.4 kg ağırlığında, 8 aylık dişi Yorkshire Terrier idi. Olgu, ASD’nin neden olduğu dolaşım dinamiklerinin bozulması nedeniyle nefes darlığı yaşamaktaydı. Torakotomi altına, üç boyutlu transözofageal ekokardiyografi rehberliğinde bir Amplatzer yerleştirildi. Postoperatif iyileşme hızlı ve sorunsuz oldu. Büyümeden sonra klinik semptomlar kayboldu ve dolaşım dinamikleri stabil hale geldi. Bu yöntem, ASD’li küçük köpekler için faydalı bir tedavi seçeneği olarak dikkate alınabilir.
