Dor procedure

Surgical procedure for left ventricular reconstruction

The Dor procedure, also known as endoventricular circular patch plasty, is a surgical technique used to treat left ventricular aneurysms and ischemic cardiomyopathy. It involves reshaping the left ventricle to improve its function and reduce symptoms of heart failure.

The heart muscle, showing areas affected by ischemia.

History

The Dor procedure was developed by French cardiac surgeon Vincent Dor in the 1980s. It was designed to address the issues of left ventricular dilation and dysfunction following a myocardial infarction.

Indications

The Dor procedure is primarily indicated for patients with:

• Left ventricular aneurysm
• Ischemic cardiomyopathy
• Heart failure symptoms not responsive to medical therapy

Surgical Technique

The procedure involves the following steps:

1. Accessing the Heart: The surgeon performs a median sternotomy to access the heart.
2. Ventricular Incision: An incision is made in the left ventricle to expose the aneurysmal area.
3. Resection and Exclusion: The aneurysmal tissue is resected or excluded from the ventricular cavity.
4. Patch Plasty: A synthetic or autologous patch is sewn into place to restore the ventricular shape and size.

Benefits

The Dor procedure aims to:

• Reduce left ventricular volume
• Improve ejection fraction
• Alleviate symptoms of heart failure
• Enhance overall cardiac function

Risks and Complications

As with any surgical procedure, the Dor procedure carries risks, including:

• Bleeding
• Infection
• Arrhythmias
• Stroke
• Death

Recovery

Postoperative care involves monitoring in an intensive care unit and gradual rehabilitation. Patients may require medications to support heart function and prevent complications.

Alternatives

Alternative treatments for left ventricular dysfunction include:

• Medical therapy
• Cardiac resynchronization therapy
• Heart transplantation
