Complex Reoperation for Late Complications After Acute Type A Aortic Dissection Surgery.

The correct management of acute Type A dissection continues to be a challenge. The primary goal is to save the patient´s life. However, the decision regarding the surgical approach determines possible later complications.

Surgery for papillary fibroelastoma with uncommon location in left ventricle.

Cardiac papillary fibroelastoma is a rare tumor. Its location in the left ventricular wall is uncommon. A 59-year-old woman with 2 previous strokes presented with a tumor in the left ventricular apex.

New method of tunnelling for omental transposition in the treatment of a complex radionecrotic groin ulcer.

Omental transposition is often used for reconstruction of soft tissue in the groin. However, the potential for incisional hernia is a relative contraindication. We report the cure of a groin ulcer with omental transposition using a new method of tunnelling to avoid herniation.

[Abdominal aortic aneurysm. Endovascular treatment with fenestrated endoprothesis].

Endovascular treatment of the abdominal aortic aneurysm is consider an alternative to open surgery for high risk patients. Its goal is to exclude the aneurysm from the circulation by using an endoprothesis introduced from a femoral approach. Patients must be strictly selected to avoid possible complications.

Different clinical features of aortic intramural hematoma versus dissection involving the descending thoracic aorta.

Objective: The objective of this study is to test the hypothesis that the absence of flow communication in aortic intramural hematoma (IMH) involving the descending aorta may have a different clinical course compared with aortic dissection (AD).

Methods: We prospectively evaluated clinical and echocardiographic data in AD (76 patients) and IMH (27 patients) of the descending thoracic aorta.

Results: Patients did not differ with regard to age, gender, or clinical presentation.

SUBCOMMISSURAL IMPLANTATION OF AORTIC PROSTHESES WITH THE USE OF THE NONCORONARY SINUS AND THE FIBROUS TRIGONES.

The technique described here permits insertion of a large prosthesis into a small aortic annulus and avoids the necessity of additional procedures for enlarging the aortic ring. Inspection of the fibrous skeleton of the heart reveals that the large intervalvular trigone and the noncoronary sinus of Valsalva are remarkably elastic. Full advantage of this natural elasticity is achieved by suturing the prosthesis to the base of these structures from outside the aorta.

LOW PROFILE BIOPROSTHESIS FOR CARDIAC VALVE REPLACEMENT: EARLY CLINICAL RESULTS.

Between May 1976 and April 1977, 100 patients underwent cardiac valve replacement with a unique low profile glutaraldehyde-treated porcine aortic xenograft. These patients were classified in four groups: Group I, 43 patients who underwent isolated mitral valve replacement (MVR); Group II, 27 patients who had isolated aortic valve replacement (AVR); Group III, 10 patients who had MVR and AVR; and Group IV, 20 patients who had MVR or AVR associated with other cardiac procedures. The operative mortality for Group I was 2.
