ABSTRACT
We treated a patient with recurrent isolated tricuspid regurgitation (TR) by repeated tricuspid valvoplasty (TVP) and tricuspid annuloplasty (TAP). The patient was a 56-year-old man who had undergone TVP eight years previously. Although the tricuspid annular dilatation was not seen in the first operation, the annular dilatation with elongation of chordae was apparent at this time. The chordal plasty with ePTFE threads and TAP with Carpentier-Edward's ring were carried out successfully. Since the annular dilatation may aggravate TR in the natural course of this disease, the combination of TVP and TAP is more effective than TVP alone.
ABSTRACT
Various types of surgical techniques have been reported for the closure of complicated PDA, since Morrow first described an innovatory operative method. At our institute, extracorporeal circulation has been frequently used as a support measure for these operations to ensure the safety of the operation. Ten patients with complicated PDA were operated under extracorporeal circulation. All patients but one were adults. The reason for use of extracorporeal circulation included age, presence of atherosclerosis or calcification of the ductus, short neck ductus, ductal aneurysms, right sided descending aorta and recanalization after previous ligation. The ductus was approached through the left lateral thoracotomy in 8 patients and median sternotomy in 2. The Morrow procedure was performed in 2 patients. No hospital death occurred, although the mean duration of the hospital stay after the operation was longer in these cases than in cases with simple PDA. We conclude that the use of extracorporeal circulation is safe and effective for the closure of complicated PDA.
ABSTRACT
The patient was a 56-year-old male with an 8-year history of Behcet's syndrome, who presented with chest pain. A saccular aneurysm (4×4cm) of the descending aorta was disclosed by X-ray and CT. Impending rupture of the aneurysm was suspected and emergency surgery was performed under cardiopulmonary bypass. The aneurysm consisted of a large thrombus, and a punched-out lesion on the aorta (φ10mm) was found beneath the thrombus. Closure with a Dacron patch was carried out successfully. Pathologic examination revealed the patient to have vasculo-Behcet's syndrome. Generally this desease has a poor prognosis, especially if an aneurysm is present, since sudden rupture can occur. Thus, prompt surgical treatment of the aneurysm should be considered. The patient was free of recurrence at the time of writing this report.
