Percutaneous Closure of Ventricular Septal Defect

Percutaneous Closure of Ventricular Septal Defect (VSD) is a minimally invasive procedure used to close a hole in the ventricular septum, the wall that separates the two lower chambers (ventricles) of the heart. VSD is a congenital heart defect in which there is a hole present since birth, allowing blood to flow abnormally between the ventricles. The percutaneous closure procedure involves the insertion of a specialized device to close the VSD, preventing the abnormal blood flow and promoting normal heart function.

 

Types

There are several types of VSD closure devices, but the most common one is the Amplatzer VSD Occluder. The device is made of a wire mesh and is folded to fit into a catheter. Once positioned, the device is released and opens up like an umbrella to cover and close the VSD.

 

Treatments

Percutaneous VSD Closure is performed to:

  • Prevent complications: If left untreated, a VSD can cause various complications, such as heart failure, abnormal heart rhythms (arrhythmias), and pulmonary hypertension.
  • Improve heart function: Closing the VSD can improve heart function by preventing abnormal blood flow and reducing strain on the heart.

 

Before the procedure

Preparing for VSD Closure may involve:

  • Medical evaluation: Your healthcare team will perform a comprehensive assessment of your overall health, including imaging tests and diagnostic procedures.
  • Medication management: You may be advised to adjust or stop certain medications before the procedure, as directed by your healthcare provider.
  • Fasting: You will be instructed to fast for a specified period before the procedure to ensure an empty stomach.

 

During the procedure

  • Anesthesia: The procedure is typically performed under general anesthesia to ensure you are asleep and pain-free throughout.
  • Catheter insertion: A catheter is inserted into a blood vessel, usually in the groin or leg, and guided to the heart using imaging techniques.
  • Device placement: The VSD closure device is advanced through the catheter and positioned at the site of the defect. The device is then released to close the VSD permanently.
  • Evaluation and adjustments: The position and effectiveness of the closure device are evaluated using imaging, and adjustments may be made to ensure proper closure.

 

After the procedure

  • Recovery: You will be closely monitored in a recovery area until you are stable. The procedure is typically performed on an inpatient basis, and most patients stay in the hospital for observation for a day or two.
  • Follow-up care: Regular follow-up appointments will be scheduled to monitor your progress and evaluate the success of the VSD closure.

 

Advantages

  • Minimally invasive: VSD Closure is a less invasive alternative to traditional open-heart surgery, leading to reduced pain, shorter hospital stays, and faster recovery.
  • Improved heart function: Closure of the VSD can improve heart function by preventing abnormal blood flow and reducing strain on the heart.

 

Risks

While VSD Closure is generally considered safe, there are potential risks and complications, including:

  • Device-related complications, such as device dislodgement, migration, or embolization
  • Blood vessel damage or bleeding at the catheter insertion site
  • Allergic reactions to anesthesia or contrast agents
  • Infection
  • Rarely, the possibility of heart rhythm abnormalities or stroke during the procedure

 

Typical recovery time

The recovery period after VSD Closure is usually short. Most patients can resume normal activities within a few days to weeks, depending on individual healing and the extent of the procedure.

 

Results and post procedure care

VSD Closure is generally considered effective in closing the defect and preventing complications associated with the defect. However, individual results may vary, and long-term follow-up is necessary to evaluate the success of the closure and monitor for potential complications.

Following VSD Closure, you may be advised to:

  • Take prescribed medications, such as antibiotics or anti-inflammatory drugs, as directed.
  • Follow up with your healthcare provider for further evaluation and management of the underlying condition.
  • Monitor for any signs of complications, such as increased pain, swelling, redness, fever, or difficulty breathing, and promptly report them to your healthcare provider.
