Sinus of Valsalva aneurysm is a rare disease characterized by the partial elevation of the aortic root. Few reports are available on the surgical treatment for infants. We report the repair of an extremely rare case of a sinus of Valsalva defect with a ventricular septal defect and right ventricular outflow tract stenosis in an infant. It was not a sinus of Valsalva aneurysm, but it exhibited abnormal partial bulging of the aortic root and forming an aneurysm-like cavity within the right ventricular myocardium. We performed direct closure of the sinus of Valsalva aneurysm-like cavities and intracardiac repair in two stages. Three years after total repair, the patient remained healthy and asymptomatic.

Left ventricular assist devices (LVAD) are widely applied for patients with severe heart failure as a bridge to heart transplantation as well as destination therapy. Patients with implanted LVAD have an increased risk of cerebral thrombosis and computed tomographic perfusion (CTP) has the potential to be performed for early diagnosis and treatment of acute ischemic stroke (AIS), including interventional thrombectomy. Here, we report our series of CTP examination in patients having suspected AIS after LVAD implantation. We retrospectively investigated 33 contrast-enhanced CTPs from January 2017 to December 2018 which were performed in 12 cases of patients because of possible neurological findings leading to suspected AIS during LVAD circulatory support who did not have definite ischemic findings nor intracerebral hemorrhage on non-contrast computed tomography. AIS with perfusion disturbance area was diagnosed in 11 (33.3%) out of a total of 33 CTPs in 4 (33.3%) out of 12 patients. Endovascular thrombectomy (EVT) was successfully performed in this research study four times for three patients. CTP was able to detect and determine the indication for EVT without serious complications. CTP could potentially be the first-choice assessment for early diagnosis of AIS with recoverable ischemic penumbra in patients with LVAD implantation.

The Rastelli operation is a useful technique for treating the transposition of the great arteries. However, conduit stenosis of the right ventricular outflow tract is a late complication of the procedure. We report the case of a 35-year-old man for whom an arterial switch operation was performed to treat conduit stenosis and improve ventricular arterial alignment 28 years after he underwent a Rastelli operation to treat transposition of the great arteries with a ventricular septal defect. In the 8 years that followed the operation, he was asymptomatic and was treated with warfarin.

A 70-years old man was referred to our department for acute heart failure due to post myocardial infarction papillary muscle rupture. We planned emergent surgery, but he refused blood transfusion because of religious reason( Jehovah's Witness). Therefore, we chose medical therapy using intra-aortic balloon pumping and catecholamine. He was also treated with subcutaneous erythropoietin and intravenous iron supplement to increase preoperative hemoglobin. One month later, we decided to undergo mitral valve repair because he was stabilized with medical treatment. The patient underwent mitral valve repair with artificial chordae through median sternotomy. The mitral valve A3 prolapse was caused by posterior papillary muscle rupture. No blood transfusion was given and postoperative course was uneventful. We experienced successful mitral repair for post infarction papillary muscle rupture in a Jehova's Witnessess patient.

Surgical treatment of cardiac fibroma is rare in patients with left ventricular noncompaction (LVNC). Although several case reports regarding cardiac fibroma have been published, resection in a patient with LVNC has not been described. Here, we describe the surgical treatment of left ventricular fibroma in a child with LVNC. We resected a cardiac fibroma in a 10-year-old boy with LVNC to control ventricular arrhythmia. Partial resection with careful tumor dissection was performed to avoid endocardial damage and entering the ventricular cavity. The postoperative course was uneventful, and the patient remains asymptomatic without heart failure or arrhythmia. Surgical excision of cardiac fibroma can be performed safely with excellent results, even in a child with LVNC.

An 81-year-old woman who presented with chest and back pain was diagnosed as aortopulmonary fistula caused by rupture of an aortic arch aneurysm and was transferred to our hospital for surgical treatment. Additionally, she was diagnosed with aortic dissection( Stanford type B). Total arch replacement with open stent-grafting and direct closure of aortopulmonary fistula were performed because of her exacerbation of congestive heart failure. Manual compression of fistula during cardiopulmonary bypass was effective to control massive shunt. The patient recovered uneventfully and was transferred to other hospital for rehabilitation on postoperative day 24.

Ross procedure has been found to have a lower incidence of infective endocarditis compared to other aortic replacement procedure using prosthetic valves. We report a case of 25-year-old man who underwent Ross procedure for congenital aortic stenosis and regurgitation when he was 7 years old. He presented with fever and was highly suspected of infective endocarditis. All sets of blood cultures were positive for Heamophilus parainfluenzae. Autologous pericardial pulmonary valve was severely stenotic and computed tomography (CT) scan and radio isotope (RI) scan revealed infection at the stenotic valve. We performed right ventricle (RV)-pulmonary artery (PA) conduit replacement and he was discharged after completion of intravenous antibiotic treatment. We experienced a rare case of infective endocarditis in a patient late after Ross procedure. Prophylaxis against infective endocarditis is mandatory even in patients with infection resistant Ross procedure.

BACKGROUND: The Fontan procedure is rarely performed in adults and adolescents in the present era. We review our results with the Fontan procedure in adolescents and young adults. METHODS: Between 1974 and 2010, 79 consecutive patients underwent the Fontan procedure at an age ≥ 15 years (mean age at Fontan operation, 20.3 years ± 4.5 years). Forty-five patients underwent atriopulmonary connection, 11 underwent the Bjork procedure, and 23 underwent total cavopulmonary connection. RESULTS: Ten hospital deaths (HDs) and/or early Fontan takedowns (TDs) occurred. The median follow-up period was 18.2 years (range, 0.6-37.6 years). The estimated freedom from death or TD rates was 79.7% at 5 years, 77.0% at 10 years, 73.9% at 15 years, and 63.9% at 20 years. Age was not a predictor of HD and/or TD. Freedom from death or TD after 1998 was 69.1% at 5 years, 69.1% at 10 years, and 69.1% at 15 years, and before 1997 was 82.3% at 5 years, 79.0% at 10 years, 75.5% at 15 years, and 65.1% at 20 years; there were no significant differences between the two groups. In 19 late-death patients, nine (47.4%) experienced sudden death. Among these patients, five had known arrhythmias before sudden death. CONCLUSIONS: In patients who were ≥15 years old, the surgical results of the Fontan operation were acceptable. Approximately half of the late deaths were sudden deaths, mainly occurring 10-20 years postoperatively.

BACKGROUND: Rastelli and réparation à l'étage ventriculaire (REV) procedures have been applied for biventricular repair of transposition of great arteries with ventricular septal defects and pulmonary stenosis (TGA III). In some patients with TGA III, whose tricuspid valve (TV) chordae tendineae are attached to the infundibular septum, abnormal TV chorda insertion may cause intracardiac rerouting obstruction. For such cases, we performed a conal flap" (CF) procedure involving mobilization of the infundibular septum including TV chordae as a pedicled flap. This study evaluated the long-term outcomes of this CF method. METHODS: Between October 1985 and December 1999, 17 consecutive patients with TGA III underwent a Rastelli-type or an REV-type procedure using CF. Median age at operation was 4.8 years (range, 1.5 to 14.0 years). RESULTS: The mean follow-up period was 17.8 ± 7.2 years. One hospital death and one late death occurred. The freedom from death rates were 94.1%, 94.1%, and 85.6% at 5, 10, and 15 years, respectively. The freedom from death or reoperation rates were 94.1%, 55.8%, and 46.5% at 5, 10, and 15 years, respectively. No reoperations were performed for the left ventricular outflow tract (LVOT) or TV. The average LVOT maximum flow velocity was 1.26 ± 0.50 m/s. TV regurgitation was greater than mild in 3 patients (20%) and trivial to mild in 12 patients (80%). Thirteen patients were in New York Heart Association (NYHA) functional class I, and 2 patients were in NYHA functional class II. CONCLUSIONS: The long-term outcomes, including the daily life activities, LVOT pressure gradients, and TV regurgitation grades, were excellent in patients who underwent Rastelli-type and REV-type procedures using CF for TGA III.

Device closure of atrial septum defect was performed using an Amplatzer septal occluder in a 48-year-old patient with Marfan syndrome. Acute tamponade due to perforation was observed 2 months after catheter intervention. Careful consideration of the indication for device closure for atrium septal defect is necessary in patients with Marfan syndrome.

A warning on the danger of unretrieved device fragments and recommendations to mitigate the danger were issued by the Food and Drug Administration in January 2008. The causes of intravascular foreign bodies are classified into three main categories: improper manipulation and usage, device defects, and others, such as patient and anatomical factors. Device failure after long-term use is rarely predicted at the time of approval, since device abnormality is rarely experienced in animal studies and clinical trials conducted during development of the device. Stent fracture due to metal fatigue is one example. Complex complications could occur from simultaneous use of two or more devices with diverse characteristics. The success rate of percutaneous retrieval of intravascular foreign bodies has improved with the advances in commercially available devices. However, the procedure is not always successful and sometimes surgical removal becomes necessary. Appropriate device selection and acquisition of experience in using the device are important. When an intravascular foreign body cannot be retrieved, the risk of complication could be high. Magnetic resonance imaging examination sometimes causes adverse events, including burns due to the heat generated by metal movement. Such information should be correctly recorded. Furthermore, it is necessary to provide patients with adequate information about the characteristics of implanted devices and unretrieved fragments. We reviewed the literature on unretrieved medical device fragments and include articles that describe the Japanese experience.
