ABSTRACT: We evaluated the efficacy of autologous blood donation using recombinant human erythropoietin for elective abdominal aortic
aneurysm (AAA) surgery regarding postoperative recovery. Twenty-five AAA patients who completed surgery without receiving
a homologous blood transfusion were divided into two groups, consisting of a control group (n = 12) who did not bank any autologous blood, and a donation group (n=13) who did bank more than 800 ml of autologous blood with the use of erythropoietin. The hematocrit (Ht) level of the control
group decreased from 41.1% ± 1.2% before the operation to 36.2% ± 0.9% just afterwards (P> 0.01). In the donation group, however, the Ht did not change significantly during either the donation period or the perioperative
period. The postoperative period before oral food intake and natural defecation were both significantly shorter in the donation
group than in the control group. The first day of mobilization was also earlier in the donation group. In conclusion, autologous
blood donation using erythropoietin for AAA surgery is therefore considered to promote the early recovery of patients.

ABSTRACT: We present a rare case demonstrating a large pseudoaneurysm of the left ventricle late after mitral valve replacement due to rupture of the papillary muscle following acute myocardial infarction. A 52-year-old man, who had undergone mitral valve replacement 7 months previously, presented with severe congestive heart failure. Echocardiography and computed tomography of the chest demonstrated a large pseudoaneurysm of the left ventricle. The patch repair of the orifice of the pseudoaneurysm was successfully performed.

ABSTRACT: We report a 49-year-old woman with intravenous and intracardiac extension of uterine leiomyomatosis. After subtotal hysterectomy and salpingo-oophorectomy, an intravenous and intracardiac tumor was removed under normothermic cardiopulmonary bypass without cardiac arrest. Postoperatively, occlusion of the artery supplying the remaining uterine cervical stump was performed by the catheter coiling technique. More than 2 years after surgery, the patient is well without recurrence.

ABSTRACT: Since we developed the procedure in 1996, we have now performed 100 pediatric open heart operations using a lower midline skin incision and a minimal sternotomy approach.
To elucidate the benefits of this approach, we analyzed these 100 cases retrospectively. There was no death, and no major complication, caused by this approach, and the resulting scarring in each patient is difficult to be seen under a common undershirt.
This review shows that the technique of a lower midline skin incision and minimal sternotomy approach is a safe reliable and cosmetically advantageous method for a pediatric cardiac operation.

ABSTRACT: Triple-barreled aortic dissection is a rare form of aortic dissection associated with high mortality. We report herein the
case of a 41-year-old woman with Marfan's syndrome who developed acute triple-barreled aortic dissection from a Stanford type
B dissecting aneurysm. Successful graft replacement of the proximal third of the descending thoracic aorta was subsequently
performed. To the best of our knowledge, this is the first case of successful operative treatment for an acute triple-barreled
aortic dissection ever to be reported.

ABSTRACT: Papillary fibroelastoma is a rare, benign cardiac tumor that can cause multiple emboli. We report herein a case of papillary
fibroelastoma developing from the chordae of the tricuspid valve which was detected by echocardiography and confirmed by surgical
resection. To our knowledge, this is only the fifth documented case of a tricuspid valve papillary fibroelastoma detected
by echocardiography in a living patient.

ABSTRACT: Three cases of thymolipoma, seen in a 6 year old boy, a 34 year old woman and a 24 year old man are presented herein. The
weight of each tumor was 1380 g, 670 g and 560 g respectively. The 2 male patients had no symptoms and the woman only complained
of a fever. On CT scan the thymic tissue was recognized as islands of soft tissue density within a fatty mass, and T1 weighted
MRI was helpful in demonstrating the predominant fatty nature of this tumor. Thus, our experience demonstrates that CT and
MRI are valuable for establishing a diagnosis of thymolipoma. In a review of the literature on the subject, some clinical
features of this non-malignant tumor in the mediastinum are discussed. Although rare, thymolipoma should be considered in
the differential diagnosis of mediastinal tumors.

ABSTRACT: Background. Many surgeons recommend early repair of doubly committed subarterial ventricular septal defect regardless of the clinical symptoms. We reviewed our patients of this anomaly with aortic cusp prolapse to justify this strategy.Methods. We reviewed the preoperative and postoperative records of 27 patients with doubly committed subarterial ventricular septal defect and aortic cusp prolapse. The patients’ ages ranged from 2 months to 11 years (median, 4.6 years).Results. During the preoperative observation period, aortic regurgitation (AR) developed in 65% of the patients. In the 8 patients without AR before the operation, AR did not develop after the operation, whereas AR persisted in 12 (63%) of the 19 patients with preoperative AR. To identify the risk factors for persistent AR after the operation we analyzed the data for the patients with preoperative AR in the persistent AR group (n = 12) and eliminated AR group (n = 7) and found a longer period from the onset of AR to the operation in the persistent AR group (32.1 ± 10.1 versus 5.6 ± 1.9 months; p = 0.014). During the follow-up period 10 of the 17 patients with mild AR before the operation showed persistent AR in the postoperative period, but it did not progress.Conclusions. We conclude that early surgical repair with a minimum observation period is essential for prevention of residual AR. Even if a tiny AR is detected preoperatively, the patient should be surgically treated immediately.
