RESUMEN
The recent 10-year progress and prospective views of the Board Certificated Cardiovascular Surgeon in Japan were described. Although total framework of the Japanese Board of Medical Specialist is not yet established, the certification standards of the Board Certificated Cardiovascular Surgeon and training hospital were substantially revised in 2005 and 2006 for increasing those quality. Hereafter, we should tackle to make new systems for the trainee's registration, gaining of incentive for the Board Certificated Cardiovascular Surgeon, and education of coworkers in surgical fields.

Patients who underwent only Glenn procedure after being deemed unsuitable candidates for Fontan completion are not small in number, and may develop arterio-venous (AV) pulmonary malformations during the follow-up period. We present the case of a 17-year-old woman with severe systemic desaturation 13 years after Glenn procedure and repair of total anomalous pulmonary venous return. Among other anomalies, the patient disclosed hemiazygos continuation to a persistent left superior vena cava. This case supports the concept that returning flow from the abdominal vein plays an important role in the well-balanced growth of the pulmonary artery and in the inhibition of the pulmonary AV malformation.

Composite graft infection after aortic root replacement is a serious complication and requires surgical reintervention with a high mortality rate. We report two cases of composite graft infection 3 months and 44 months after the primary operation. Each successfully underwent redo aortic root replacement with a new composite graft and a Freestyle stentless bioprosthesis, respectively. Both patients are currently well and without recurrence of infection 35 months and 48 months postoperatively.

We report the case of a patient who underwent treatment for a macroembolism in the right lower leg, which led to shaggy aorta syndrome. Anticoagulant therapy for the macroembolism and intra-aortic catheterization exacerbated the patient's renal function and triggered another massive microembolization of the visceral arteries, with a fatal outcome. To minimize the incremental complications inherent to this syndrome, awareness and prompt diagnosis with enhanced computed tomography or intravenous digital subtraction aortography are essential. Axillo-bifemoral bypass with bilateral external iliac artery ligations, performed with optimal timing, could save patients with shaggy aorta syndrome.

BACKGROUND: Tetralogy of Fallot with subarterial ventricular septal defect is frequently seen among Asians. Compared with infracristal ventricular septal defect, postoperative right ventricular outflow obstruction is more likely because of subpulmonary extension of the defect. Moreover the incidence of aortic regurgitation is a concern because of the absence of a supporting infundibulum. METHODS: Four hundred cases of classic tetralogy were reviewed, 61 of which had subarterial ventricular septal defect. RESULTS: Aortic regurgitation (of more than mild degree) was identified in 7 cases with subarterial and 7 with infracristal ventricular septal defects. The mechanism of infracristal defect was predominantly an annular dilation before surgery. In contrast 5 cases with subarterial defect had progression of aortic regurgitation after operation yielding an actuarial incidence of 29.7% at 20 years. In 2 patients the cause seemed to be fixation or plication of the aortic valve annulus by the ventricular septal patch. Compared with infracristal defect, subarterial defect was associated with increased incidence of reoperation (12.0% versus 1.9% at 10 years, p = 0.01), frequent use of transannular patch (70.5% versus 45.7%, p = 0.0004), and worse New York Heart Association (NYHA) functional class (p = 0.007). Right ventricular outflow obstruction was the reason for reoperation in 3 patients with subarterial defect and was associated with worse NYHA classification in the long-term, on multivariate analysis (p = 0.0002). CONCLUSIONS: Tetralogy with subarterial ventricular septal defect was associated with worse functional outcome. To prevent adverse outcomes, precise suturing of the distal ventricular septal patch, extensive infundibulectomy, lower threshold for transannular incision, and smaller-sized ventricular septal patch placement are warranted.

Long-term mortality from congenital cardiovascular malformations (CCVM) remains unknown in most countries. Age- and sex-specific mortality rates from CCVM in Japan from 1968 through 1997 were determined from analyses, with official permission, of individual death records held by the Japanese Government. CCVM with chromosomal anomalies were not included. The number of deaths analyzed was 82,919. The mortality rate declined by 64% from 3.36 per 100,000 population in 1968 to 1.22 in 1997, largely because of a decrease in mortality among patients under 20 years of age. Infant mortality remained high until 1978, then sharply declined from 1979 to 1987 with the advent of 2-dimensional echocardiographic diagnosis and prostaglandin El therapy. The cumulative mortality rates in the first 20 years of life were expected to decline among cohort members born after 1978. In contrast, the mortality rates for subjects over 20 years of age increased during the 30-year study period. Mortality rates were higher for males than for females. The mortality rate among young patients with CCVM is expected to decline still further, suggesting that many if not most children with CCVM will survive to adulthood.
