Left Atrial appendage (LAA) closure in cases of atrial fibrillation – Protection against strokes

If you suffer from atrial fibrillation, you have an increased risk of stroke. In many cases, these are caused by blood clots in the left atrium. LAA occlusion is a procedure that can permanently reduce this risk without the need for lifelong anticoagulant medication. At our centre, we offer two proven methods: catheter occlusion via the groin and surgical occlusion via a small incision. Both procedures are performed by internationally renowned specialists at our centre.

Why close the LAA?

The LAA is a small protrusion located in the left atrium of the heart. In cases of atrial fibrillation, blood can accumulate there and form clots. These clots can reach the brain and cause a stroke.

Closing the LAA can significantly reduce this risk, especially in people who cannot or do not want to take anticoagulants.
Advantages of atrial occlusion:

  • Protection against strokes
  • Avoids long-term anticoagulant use
  • Suitable for people at high risk of haemorrhage (bleeding)
  • Permanent solution thanks to a single procedure

Who is this procedure suitable for?

LAA occlusion may be considered if:

  • You suffer from atrial fibrillation and are at increased risk of stroke,
  • you cannot tolerate anticoagulants or have already experienced bleeding,
  • you have had a stroke despite taking anticoagulants,
  • you wish to stop taking these medications permanently,
  • you are planning to undergo catheter ablation to treat your atrial fibrillation anyway.

The decision is made individually with you after a thorough consultation.

Two ways to achieve the goal: catheter or surgery

1. LAA Closure using a catheter

This procedure is performed through a small incision in the groin. A special ‘umbrella’ is inserted into the atrium via a catheter and closes it permanently, without open surgery. Prof. Dr Horst Sievert, one of the world's most experienced specialists in this field, personally contributes his many years of expertise. He was the first in the world to perform such a procedure on a human being and played a decisive role in the development of this procedure.

2. Surgical closure of the LAA

In some cases, surgical closure is recommended. The heart's atrium is then closed using a special clip (‘AtriClip®’). Prof. Dr. Sacha Salzberg played a key role in the development of the AtriClip® and performed the first implantation of this clip in humans in 2007. Today, this clip is used worldwide in cardiac surgery.

How is the catheter procedure performed?

  • Access via the femoral vein under local anaesthesia.
  • The closure system is inserted into the atrium using a thin catheter.
  • The umbrella is placed in the LAA and deployed.
  • Ultrasound control (via the oesophagus or using an ultrasound device placed in the heart).
  • At our clinic, the procedure is performed on an outpatient basis.

What makes us special:
In certain circumstances, we can combine atrial closure with catheter ablation for atrial fibrillation, all in a single procedure.

What systems do we use?

We use modern, proven systems that are used worldwide:

  • Watchman FLX® (Boston Scientific)
  • Amplatzer Amulet® (Abbott)
  • LAmbre® (Lifetech)

Advantages

  • No need for long-term anticoagulant medication
  • Protection against stroke as effective as medication
  • Outpatient procedure
  • Also suitable for elderly patients or those with a medical history

We will provide you with detailed information about the chances and risks during an individual consultation.

Frequently asked questions

How long does the procedure take?

The catheter procedure usually takes 30–60 minutes. If ablation is performed at the same time, it takes a little longer.

How long do I have to stay in hospital?

We perform the procedure on an outpatient basis.

Will I need to take medication afterwards?

Two blood-thinning medications (e.g. ASA + clopidogrel) are often administered for several weeks after the procedure. After that, often only one – or none at all.

When can I be active again?

Light exercise is usually possible the next day. Sports are usually possible after a few days.
