Figure

  • Figure 1 Echocardiogram, abdominal enhanced CT, and gastroscopy.(A) Apical 4 chamber view shows incomplete coaptation of tricuspid valve with severe tricuspid regurgitation by color doppler echocardiogram. (B) Abdominal enhanced CT scan illustrates significant contrast reflux into the hepatic veins and inferior vena cava. (C) Gastroscopy reveals submucosal congestion and erythema in the gastric body, suggesting congestive gastropathy.CT = computed tomography.

  • Figure 2 CAVI using self-expandable valve.(A) Cavogram by using a pigtail catheter through the right jugular vein reveals the locations of the RA, IVC, and hepatic veins. (B) After the placement of a 20 Fr sheath through the left femoral vein, a small pre-shaped Safari wire was located at the right atrium. After then, a large-diameter bare-metal stent (Niti-S® 30×60 mm; TaeWoong Medical) was placed from the junction of the IVC and RA to distal IVC beyond hepatic veins for the supporting frame to prevent valve migration. (C) Pulsta® (30×38 mm; TaeWoong Medical) valve was gradually deployed in the IVC-RA junction with about 5 mm RA protrusion. During the implantation process, a snare was used to hold the Niti- S® stent not to be dragged up. (D) Final fluoroscopy shows successful CAVI without any complication.CAVI = caval valve implantation; IVC = inferior vena cava; RA = right atrium.

  • Figure 3 CT, echocardiogram, and liver sonogram after CAVI.(A) CT (post CAVI, reconstructed image) scan reveals blocking contrast reflux into hepatic vein compared to CT before CAVI. (B) Echocardiographic subcostal view shows implanted caval valve. (C) Liver sonogram demostrates mild hepatic venous stenosis without obstruction.CAVI = caval valve implantation; CT = computed tomography; IVC = inferior vena cava; RA = right atrium.

  • Figure 4 Pre-CAVI and post-CAVI chest X-rays.(A) Chest X-ray shows cardiomegaly and pleural effusion. (B) Chest X-ray after CAVI shows improving cardiomegaly and pleural effusion.CAVI=caval valve implantation.
