Kordalar normalden kısa ve triküspid kapak açılımı hafif kısıtlıydı. Sürekli akım Doppler ile triküspid kapakta, en yüksek ve ortalama diya-stolik gradiyentler sırasıyla 8 mmHg ve 4 mmHg olarak ölçüldü. Renkli Doppler ile 1-2. derece triküspid yetersizlik saptandı. “Paraşüt triküspid kapak” ön tanısı ile kapak altı yapıların daha ayrıntılı değerlendirilmesi

amacıyla çok kesitli kardiyak bilgisayarlı tomografi (ÇKBT) uygulandı. ÇKBT’de triküspid kapağa ait tek papiller kas olduğu net olarak görüldü ve tanı doğrulandı (Resim 3). Triküspid kapağın tek bir papiller kas grubundan korda alması ‘paraşüt triküspid kapak’ olarak adlandırılır ve oldukça nadirdir. Paraşüt deformitesi triküspid kapakta değişen oran-larda darlık ve/veya yetersizliğe neden olur. Hastalar ciddi triküspid darlık semptomları ve konjestif kalp yetersizliği ile başvurabilirler. Olgumuz gibi kapak etkilenimi hafifse, asemptomatik de olabilirler. Paraşüt triküspid kapak olgularında tedavi şekline hastanın semptomları ve eşlik eden ilave anomalilere göre karar verilir. Hastamız asemptoma-tik olduğu için triküspid kapağa yönelik herhangi bir girişim düşünmedik; ancak ciddi sağ kalp yetersizliği semptom ve bulguları mevcut olsaydı, kararımız cerrahi olacaktı.

Right atrial hemangioendothelioma: a

three-dimensional echocardiographic

evaluation

Sağ atriyal hemanjiyoendoteliyoma: Üç-boyutlu

ekokardiyografik değerlendirme

A 25-year-old man was referred to our center for further evaluation of mediastinal mass first detected at chest radiography. Before referral, a thorax computed tomography had been performed and a 4x14 cm heterogeneous mass located at anterior mediastinum had been revealed. He had also undergone a thoracotomy to obtain biopsy, revealing hemangioendothelioma at histopathological examination. On physical examination, right heart failure signs were present. A two-dimensional transthoracic echocardiography (2D echo) was performed, demonstrating a mass located in right atrium extending to right ventri-cle. At subcostal window, inferior vena cava was dilated with no respi-ratory change and mass was also found to be extending to superior vena cava (Fig. 1). However, on 2D echo examination, it was not com-pletely determined whether mass was located in the right atrium or its image was superimposed on the right atrium. Due to its superior resolu-tion, a three-dimensional echocardiogram (3D echo) was obtained. Mass was found to be located in right atrium and invaded right ventricle wall, extending to superior vena cava on 3D echo examination (Video 1. See corresponding video/movie images at wwww.anakarder.com).

Also, multiple echolucent areas with sparse solid tissue were visualized within the mass (Fig. 2, Video 2. See corresponding video/movie images at wwww.anakarder.com). Palliative therapy was planned due to bone metastasis, diffuse local invasion of other mediastinal and vascular structures.

Cardiac hemangioendothelioma is an extremely rare cardiac tumor with high vascularity and sparse solid tissue at histopathological examination. Although 2D echo provides considerable anatomic data regarding intracardiac masses, complex spatial location and extension of these masses may be better defined by 3D echo. It may also give information about mass structure, such as multiple echolucent areas compatible with high level of vascularity within tumor mass. Therefore, 3D-echo may provide better information before planning surgery of intracardiac masses.

Four-chamber MRI showed extracardiac mass lesion which compress right atrium (yellow arrow) and bilateral pleural effusion (red asterix) with compression atelectasis in lower lobe

Last echocardiographic examination showed no thrombi in hepatic veins, inferior vena cava or right atrium (Fig. See correspond- ing video/movie images at www.anakarder.com)..

Two-dimensional (2-D) echocardiography showed a 7x3 cm mobile mass in the right ventricle extending into right ventricular outflow tract (Video 1.. See video/movie images

In the subcostal view, this mass was extending from inferior vena cava (IVC) through the right atrium (Fig. See corresponding video/movie images at www.anakarder.com)..
