# Right Lower Pulmonary Vein Thrombi and Right Upper Pulmonary Vein Thrombi Connected on the Anterior Wall of the Left Atrium

## TL;DR

This study shows for the first time that blood clots in two pulmonary veins can connect on the left atrium's anterior wall using advanced imaging techniques.

## Contribution

First direct demonstration of RUPV and RLPV thrombi connection on the LA anterior wall using TEE and 80-MDCT.

## Key findings

- RUPV and RLPV thrombi invade the left atrium and reach its anterior wall.
- The connection between RUPV and RLPV thrombi was directly visualized using TEE and 80-MDCT.
- This connection was previously unknown and highlights a new anatomical interaction.

## Abstract

The interaction between the right upper pulmonary vein (RUPV) and the right lower pulmonary vein (RLPV) is poorly understood. In this paper, using transesophageal echocardiography (TEE) and 80-slice multidetector computed tomography (80-MDCT), we report that the RUPV thrombi and the RLPV thrombi invade the left atrium (LA) and reach the anterior wall of the LA. To our knowledge, this is the first study to directly show the connection between the RUPV thrombi and the RLPV thrombi on the anterior wall of the LA using TEE and 80-MDCT.
