The PVLs were mainly localized in theposterior and anterior annular positions between 12 to03 hours (n=7) and 06 to 09 hours (n=3) on RT-3D TEE,respectively, which corresponded to the posteromedial oranterolateral sectors of the posterior annulus.Conclusion: Considering that only the width of thePVL defect can be assessed by 2D TEE, delineationby RT-3D TEE includes the localization of PVL togetherwith the length and width of the defect.

Abstract

Objectives: Two-dimensional (2D) echocardiographicapproaches are not sufficient to determine the origin ofparavalvular leak (PVL) that occurs after prosthetic mitralvalve replacement (MVR). In this study, we investigatedthe role of real-time three-dimensional transesophagealechocardiography (RT-3D TEE) in detecting the originand size of PVL occurring after prosthetic MVR.Study design: The study included 13 patients (7 females;6 males; mean age 56±10 years; range 37 to 71 years) whodeveloped PVL within a mean of 8.3±3.8 years followingmechanical prosthetic MVR. Nine patients (69.2%) hadatrial fibrillation, and four patients (30.8%) had normal sinusrhythm. Four patients (30.8%) had hemolysis. Paravalvularleak was mild, moderate, and severe in two, six, and fivepatients, respectively. Real-time 3D TEE was performedusing a 3D matrix-array TEE transducer immediately afterdetection of PVL on 2D TEE examination. Localization ofPVL was made using a clock-wise format in relation to theaortic valve and the size of dehiscence was measured.Results: The mean PVL width measured by 2D TEEwas 3.00±0.92 mm. The mean length of dehiscence was13.6±8.8 mm, and the mean width was 3.88±2.04 mmon RT-3D TEE. The PVLs were mainly localized in theposterior and anterior annular positions between 12 to03 hours (n=7) and 06 to 09 hours (n=3) on RT-3D TEE,respectively, which corresponded to the posteromedial oranterolateral sectors of the posterior annulus.Conclusion: Considering that only the width of thePVL defect can be assessed by 2D TEE, delineationby RT-3D TEE includes the localization of PVL togetherwith the length and width of the defect.

Özet

Amaç: İkiboyutlu (2B) ekokardiyografik yöntemlerle,prostetik mitral kapak değişiminden sonra görülebilenparavalvüler kaçak (PVK) yeri tam olarak gösterilememektedir. Bu çalışmada, protez kapak değişimi sonrasıPVK gelişen olgularda, PVK kaynağının ve boyutunungösterilmesinde gerçek zamanlı üçboyutlu transözofageal ekokardiyografinin (3B TÖE) değeri araştırıldı. Ça lış ma pla nı: Çalışmaya, mekanik kapak değişimindenortalama 8.3±3.8 yıl sonra PVK gelişen 13 hasta (7 kadın,6 erkek; ort. yaş 56±10; dağılım 37-71) alındı. Dokuz hastada (69.2%) atriyal fibrilasyon bulunurken, dört hasta(%30.8) normal sinüs ritmindeydi. Dört hastada (%30.8)hemoliz vardı. İki hastada hafif, altı hastada orta, beşhastada ileri derecede PVK vardı. İkiboyutlu TÖE ile PVKsaptanmasından hemen sonra hastalara 3B matriks dizi- limli TÖE transdüser ile gerçek zamanlı 3B TÖE yapıldı.Paravalvüler kaçak yeri, aort kapağına göre konumlandırılan saat kadranı düşünülerek işaretlendi ve ayrışmaboyutları ölçüldü. Bul gu lar: İkiboyutlu TÖE’de ortalama PVK genişliği3.00±0.92 mm ölçüldü. Gerçek zamanlı 3B TÖE’de iseayrışma boyu 13.6±8.8 mm, genişliği 3.88±2.04 mmbulundu. Paravalvüler kaçak yeri 3B TÖE’de sırasıylaposteriyor ve anteriyor anülüs taraflarında, 12-03 (n=7) ve06-09 (n=3) saatleri arasında ve mitral arka yaprak anülüsünün posteromedial ve anterolateral komissürlerindeyoğunlaşmaktaydı. So nuç: İkiboyutlu TÖE’de PVK’nin sadece genişliğininölçülebildiği göz önüne alındığında, gerçek zamanlı 3BTÖE ile PVK’nin hem yeri belirlenebilmekte, hem dedefektin boy ve genişliği hesaplanabilmektedir.
