  Abstract 


We report this case, which described the echocardiographic and chest X-ray appearance of the amplatzer device. The echo images raised suspicion of a mass in the left atrium, but a simple X-ray showed that the mass is an amplatzer device for left atrial appendage closure.

Keywords: Amplatzer, atrial fibrillation, left atrial appendage closure

On presentation, a 65-year-old woman complained of dyspnea on exertion. Her son reported a history of hypertension and that a pacemaker was inserted. She developed an irregular pulse, and a direct oral anticoagulant was prescribed, however, she developed alveolar hemorrhage after the treatment. The decision was made to perform a second percutaneous cardiac intervention. Her transthoracic echocardiography showed an abnormal shadow [[Figure 1]-arrow]. The same shadow was noted in other standard echo views: apical 2 and 3.

  Question Top


  1. What is the abnormal finding and what is the diagnosis?
  2. Which simple test revealed the diagnosis?



  Answer Top


  1. The amplatzer cardiac plug (ACP) device is an alternative nonsurgical method to occlude the left atrial appendage (LAA) in certain cases of atrial fibrillation (AF). During the echocardiogram examination, it may be visible as an abnormal shadow in the form of a number 8
  2. Chest X-ray disclosed the diagnosis and showed the ACP geometry [Figure 2].

  Discussion Top


The left atrium is a frequent source of embolic stroke, particularly in patients with AF.[1] The majority of AF-induced thrombi are formed in the LAA. In patients with AF, with a contraindication to use anticoagulation to prevent stroke, an alternative has been a goal for years. The introduction of the LAA percutaneous closure is a relatively safe and promising technique for the prevention of stroke.[2]

The shadow of an ACP is recognized and in the form of a number 8 on the transthoracic echocardiogram. The epitrochoid geometry of the ACP, which is the result of the interaction between the mesh and ultrasound waves, is seen as a number 8. Recognizing this artifact's shadow as normal will also serve as a method to assess the position of the device.[3]
