Central cyanosis due to prominence of the eustachian and thebesian valves.

A 9-year-old female child with serious central cyanosis was found to have right to left shunt across a large secundum atrial septal defect despite normal right-sided pressures. Preoperative cross-sectional echocardiography suggested the presence of large sinus venosus eustachian and thebesian valves as the mechanism responsible for diversion of the inferior caval and coronary sinus venous return to the left atrium across the interatrial secundum defect. Surgical excision of the unduly prominent sinus venosus valve and patch closure of the atrial septal defect resulted in complete disappearance of the cyanosis and physiological and clinical cure.

Repair of torn aortic root with the left atrial appendage.

A narrow aortic root and a small aortic annulus made aortic valve replacement in a 35-year-old female patient with calcified aortic stenosis rather difficult. At the end of the procedure, it was noticed that the aortic root was badly torn. The tear started at the end of the aortotomy incision, near the commissure between the non-coronary and left coronary cusps, ran flush with the prosthetic ring and extended beneath and a few millimeters beyond the ostium of the left coronary artery. Only a thin rim of the aortic wall was left proximally, which was not strong enough to support the sutures. The aorta was repaired using a pericardium covered Goretex patch, bolstered by the left atrial appendage.

Sinus of Valsalva aneurysm eroding into the interventricular septum.

We report a case of erosion of an aneurysm of the right sinus of Valsalva into the interventricular septum. The mode of presentation, the preoperative evaluation, and the echocardiographic and nuclear magnetic resonance imaging features are presented, and the cardiac catheterization findings and surgical management of this very rare cardiac pathology are discussed.

Superimposition of a mechanical valve on an impacted aortic bioprosthesis.

During reoperation for replacement of a regurgitant aortic bioprosthesis (a 23-mm bovine pericardial valve), it was judged that total removal of the valve would be difficult, and hazardous to the patient. Therefore, its leaflets were excised and its sewing ring left in situ. A 21-mm Carbomedics bileaflet mechanical valve was sutured to the bioprosthetic sewing ring and implanted in the orifice of the bioprosthesis, resulting in excellent hemodynamic performance. We report this new technique to illustrate its feasibility, safety, and efficiency, as an alternative to complete removal of defective prostheses in the aortic position.
