TEE may have good diagnostic utility in differentiating BAV phenotypes

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objective: We investigated the frequency of different bicuspid aortic valve disease (BAV) phenotypes,the associated valvular pathologies, and the aortopathy phenotypes, using 2-dimensional (2D) transthoracic, 2D transesophageal echocardiography (TEE) and 3-dimensional (3D) TEE.Methods: A total of 154 patients with BAV were included.
📊
Key Findings & Data:Aortopathy phenotype was classified according to the involved tract(s).Results: Of the patients, 53.2% had type 1, 16.2% type 2, 15.6% type 3, 1.3% type 4, and 13.6% had type 5 BAV.

Abstract

Objective: We investigated the frequency of different bicuspid aortic valve disease (BAV) phenotypes,the associated valvular pathologies, and the aortopathy phenotypes, using 2-dimensional (2D) transthoracic, 2D transesophageal echocardiography (TEE) and 3-dimensional (3D) TEE.Methods: A total of 154 patients with BAV were included. Five BAV phenotypes were detected. To better define valvular pathologies, binary classifications of BAV were used: BAV with antero-posterior commisural line (BAV-AP) and right-left commissural line (BAV-RL). Aortopathy phenotype was classified according to the involved tract(s).Results: Of the patients, 53.2% had type 1, 16.2% type 2, 15.6% type 3, 1.3% type 4, and 13.6% had type 5 BAV. The prevalence of BAV-AP and BAV-RL was 68.2% and 31.8%, respectively. No difference was detected with respect to aortic regurgitation between BAV-AP and BAV-RL (p=0.9), but the BAVRL group had an increased propensity to have a stenotic aortic valve (p=0.003). The indexed aortic diameter was larger in BAV-AP cases than BAV-RL at the sinus of Valsalva (p=0.008). In patients with dilatation of the root and tubular portion, a predominance of BAV-AP versus BAV-RL was observed (85% vs 15%). A markedly low prevalence of the root phenotype (3.2%) was observed. In 90.1% of the patients, 2D TEE was sufficient to classify BAV phenotypes; further 3D imaging was needed in 9.9% of the cases.Conclusion: There may be racial differences in the frequency of valvular and aortopathy phenotypes in patients with BAV. BAV phenotypes differ with respect to aortic stenosis and aortopathy phenotypes. TEE may have good diagnostic utility in differentiating BAV phenotypes

Özet

Amaç: Farklı biküspit aort kapak (BAK) fenotiplerinin dağılımını, kapak patolojilerini ve aortopati fenotiplerininin dağılımını iki boyutlu (2B) transtorasik, 2B transözofajiyal ekokardiyografi (TÖE) ve 3B TÖE kullanarak araştırdık ve de bu incelemelerin BAK fenotiplendirmesinde kullanım yerini değerlendirdik.Yöntemler: BAK'lı 154 hasta çalışmaya alındı. Beş BAK fenotipi saptandı. Kapak patolojilerini daha iyi tanımlamak için ikili BAK sınıflandırması şu şekilde kullanıldı: Ön-arka komissür çizgisinin olduğu BAK-ÖA ve sağ-sol komissür çizgisinin olduğu BAV-SS. Aortopati fenotipleri tutulum olan kısımlara göre sınıflandırıldı.Bulgular: Hastaların %53.2'sinde tip 1, %16.2'sinde tip 2, %15.6'sında tip 3, %1.3'ünde tip 4 ve %13.6'sında tip 5 BAK alt tipi saptandı. BAK-ÖA ve BAK-SS'nin prevalansı sırasıyla %68.2 ve %31.8 idi. BAK-ÖA ve BAK-SS, kapak patolojileri açısından karşılaştırıldığında aort yetersizliği açısından fark yokken (p=0.9), BAK-SS grubunda daralmış bir kapak bulundurma eğilimi daha yüksekti (p=0.003). Sinüsler düzeyinde endekslenmiş aort çapı BAK-ÖA'da BAK-SS'ye göre daha genişti (p=0.008). Kök ve tübüler bölümün genişlediği hastalarda BAK-ÖA saptanma sıklığı BAK-SS saptanma sıklığına göre daha yüksekti (%85'e karşı %15). BAK popülasyonumuzda kök fenotipi (%3.2) belirgin olarak azdı. 2B TÖE hastaların %90.1'inde BAK fenotipini belirleyebildi ve 3B görüntülemeye olguların %9.9'unda ihtiyaç duyuldu.Sonuç: BAK'lı hastalarda kapak ve aortopati fenotiplerinin sıklığında ırksal değişiklikler olabilir. BAK fenotipleri aort darlığı ve aortopati açısından farklılıklar göstermektedir. BAK fenotipini belirlemede TTE'nin düşük yararına karşın TÖE iyi bir tanısal fayda sağlayabilir
