Dor procedure
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.
History[edit]
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[edit]
The Dor procedure is primarily indicated for patients with:
- Left ventricular aneurysm
- Ischemic cardiomyopathy
- Heart failure symptoms not responsive to medical therapy
Surgical Technique[edit]
The procedure involves the following steps:
- Accessing the Heart: The surgeon performs a median sternotomy to access the heart.
- Ventricular Incision: An incision is made in the left ventricle to expose the aneurysmal area.
- Resection and Exclusion: The aneurysmal tissue is resected or excluded from the ventricular cavity.
- Patch Plasty: A synthetic or autologous patch is sewn into place to restore the ventricular shape and size.
Benefits[edit]
The Dor procedure aims to:
- Reduce left ventricular volume
- Improve ejection fraction
- Alleviate symptoms of heart failure
- Enhance overall cardiac function
Risks and Complications[edit]
As with any surgical procedure, the Dor procedure carries risks, including:
Recovery[edit]
Postoperative care involves monitoring in an intensive care unit and gradual rehabilitation. Patients may require medications to support heart function and prevent complications.
Alternatives[edit]
Alternative treatments for left ventricular dysfunction include:
