Effectiveness of home care for fever treatment in older people: A case-control study compared with hospitalized care.

AIM: To examine whether the outcomes of fever treatment through home care differ from those through hospitalized care for older people who regularly receive home care in Japan. METHODS: A retrospective survey of medical record-based data for 679 older people who regularly received home care provided by a clinic in Japan. From these data, 61 fever cases (21 cases treated in the hospital and 40 treated at home and assigned to the hospitalized and home-care groups, respectively) were selected for analysis through a matching process. We compared the two groups in terms of mortality rate at 90 days after fever onset, and concerning changes in respective ranks for "Degree of Independent Living for the Elderly with Disability" and "Degree of Independent Living for the Elderly with Dementia" from immediately before fever onset to 90 days after fever onset. RESULTS: The mortality rate tended to be higher in the hospitalized group than in the home-care group (33% vs. 13%, respectively, P = 0.05). The hospitalized group also had a higher proportion of patients whose disability had worsened (43% vs. 23%, respectively, P = 0.16) and a significantly higher proportion of patients whose dementia had worsened (29% vs. 6%, respectively, P = 0.03). CONCLUSIONS: Our findings suggest that home care is more effective than hospitalized care for treating fever in older people who regularly receive home care in Japan, as it leads to lower mortality and better maintenance of activities of daily living capabilities.

Outcomes of swing-back aortic arch repair in arterial switch and Norwood operations.

The outcomes of the swing-back technique for aortic arch repair during the arterial switch and Norwood operations are not well reported. Between May 2004 and January 2011, we performed this technique during the arterial switch and Norwood operations in 2 and 4 patients, respectively. The median (range) patient age and body weight were 17 (12-147) days and 3.4 (2.2-6.1) kg, respectively. All patients survived the procedures. The median follow-up duration was 4 (1-8) years. One patient showed recoarctation in the early postoperative period, which was successfully repaired by a single-catheter intervention. The latest median pressure gradient across the neoaortic arch was 0 (0-6) mmHg. Neoaortic valve regurgitation was found to be minimal by echocardiography. During the follow-up period, the Fontan operation was performed in all the patients who underwent the Norwood operation. These results suggest that the swing-back technique yields satisfactory mid-term outcomes.

[Successful application of cholangioscope as an intravascular endoscope in hybrid operation for a child].

We performed hybrid operation on a 3-year-old boy with thrombosis in the pulmonary arterial conduit which had been implanted concomitantly at the time of Fontan operation. We used a cholangioscope as a substitute of intravascular endoscope. It visualized the organized thrombus and the suture line in the conduit. Hybrid operation was successfully performed based on the detailed findings gained by cholangioscopy.

Second-Stage Palliation After Bilateral Pulmonary Artery Bands for HLHS and its Variants--Which is Better, Modified Norwood or Norwood Plus Bidirectional Glenn?

Background. The purpose of this study was to evaluate the surgical outcomes and pulmonary artery (PA) development associated with a new strategy wherein the modified Norwood (N) procedure is performed at 1-2 months after bilateral pulmonary artery banding (PAB). Methods. Between January 2008 and February 2010, 16 patients underwent Norwood-type operation after previous bilateral PAB. For analysis, patients were divided into two groups. Group I (n = 11) underwent modified Norwood procedure with either right modified Blalock Taussig (RMBT) shunt (n = 4) or right ventricle to pulmonary artery (RV-PA) conduit (n = 7). Group II (n = 5) underwent Norwood procedure plus bidirectional Glenn anastomosis. Diagnoses were hypoplastic left heart syndrome in 6 and its variants in 10. Results. There was no surgical death and no late death. Pulmonary artery interventions were performed at the time of the Norwood procedure in 27% in Group I and in 100% in Group II (p < 0.05). Additional PA interventions were performed during the period of follow-up in 4 cases in Group I (36.4%), and in 4 cases in Group II (80.0%). Additional Blalock Taussig shunts were performed in 7 patients, resulting in significant increase in PA index. In all, four patients have reached total cavopulmonary connection, and one has undergone biventricular repair. Eight patients in Group I and one patient in II Group reached bidirectional Glenn anastomosis. In Gp II, two patients showed LPA narrowing or obstruction with PA index of 80 ± 12 mm(2)/m(2). Conclusions. Regarding the second-stage palliation after bilateral PAB, modified Norwood procedure with either RMBT or RV-PA conduit has some advantages compared with Norwood plus BDG with respect to subsequent pulmonary artery development. Additional BT shunt may contribute to PA development, even in the patients with Norwood procedure with RV-PA conduit.

Rapid two-stage Starnes procedure for a symptomatic neonate with Ebstein anomaly.

We present a rapid two-stage Starnes procedure for a seriously symptomatic neonate with the prenatal diagnosis of Ebstein anomaly. At 16 hours after birth, we performed an emergency operation consisting of main pulmonary artery ligation, plication of the right atrial and right ventricular wall, modified Blalock-Taussig shunt, and patent ductus arteriosus ligation, without cardiopulmonary bypass. At age 12 days, we then performed the Starnes procedure using a glutaraldehyde-treated autologous pericardial patch with a 4-mm fenestration to close the tricuspid valve orifice. The infant's postoperative course was excellent. A rapid two-stage Starnes procedure is useful for treating a seriously symptomatic neonate with Ebstein anomaly.

Pulmonary artery banding for functionally single ventricles: impact of tighter banding in staged Fontan era.

BACKGROUND: In this study, we assessed our surgical strategy, tighter pulmonary artery banding (PAB) during the neonatal period, as an initial step followed by early application of bidirectional cavopulmonary shunts (BCPS) in infancy, to treat functionally single ventricles with unobstructed pulmonary blood flow. METHODS: On the basis of our surgical strategy, 68 consecutive patients underwent PAB and were divided into two groups, group 1 (January 1990 to June 2003; n = 30) and group 2 (July 2003 to August 2008; n = 38). The median age at PAB was 45 days in group 1 and 9 days in group 2. The circumference of the bands was significantly shorter in group 2 than in group 1, corresponding to the patient's weight in kg plus 19.0 +/- 0.6 mm in group 1 or 17.0 +/- 0.3 mm in group 2 (p = 0.003). RESULTS: Cardiac catheterization before the right heart bypass operation showed that the pulmonary artery index (group 1, 322 +/- 29; group 2, 283 +/- 27 mm(2)/m(2); p = 0.01), pulmonary resistance index (group 1, 2.4 +/- 0.2; group 2, 1.9 +/- 0.1 U x m(2); p = 0.03), and ventricular end-diastolic volume (group 1, 212 +/- 19%; group 2, 166 +/- 9%; p = 0.04) were significantly different between the two groups. The rates for achievement of right heart bypass at 12 months (group 1, 19%; group 2, 81%; p < 0.01) and survival at 3 years (group 1, 70%; group 2, 87%; p = 0.04) were significantly higher in group 2 than in group 1. CONCLUSIONS: Our present strategy could prevent volume overload and improve the achievement and survival rates of right heart bypass operations.

Staged surgical approach in neonates with a functionally single ventricle and arch obstruction: pulmonary artery banding and aortic arch reconstruction before placement of a bidirectional cavopulmonary shunt in infants.

The success rate of right-heart bypass surgery in patients with a functionally single ventricle (f-SV) and systemic obstruction is low. In patients with a high risk of subaortic stenosis, we performed an initial step of pulmonary artery banding (PAB) and arch reconstruction before placing a bidirectional cavopulmonary shunt (BCPS) in infants with or without Damus-Kaye-Stansel (DKS) anastomosis. We assessed the success of right-heart bypass surgery. Between October 2003 and August 2008, we performed surgery in 19 neonates (median age 5 days) with f-SV and arch obstruction. Extended aortic arch anastomosis, with or without distal arch augmentation, was performed in 10 patients, and subclavian flap aortoplasty was performed in 9 patients. The circumference of the PAB was determined as the individual patient's body weight in kilograms plus 16.2 +/- 3.7 mm. Eighteen of 19 infants (95%) underwent successful BCPS placement at a median age of 7.8 months. DKS anastomosis was performed concomitantly during BCPS placement in 11 infants in whom subaortic stenosis was morphologically suspected but not demonstrated physiologically. As our first-stage operation, arch reconstruction plus PAB provided high success rates for right-heart bypass operations. This strategy is not leading, but it is a reliable approach for progression along a Fontan pathway.

Surgical treatment of an infant with myocardial ischemia due to an anomalous origin of the right coronary artery from the main pulmonary artery: report of a case.

An anomalous origin of the right coronary artery from the main pulmonary artery (ARCAPA) is a rare cardiac malformation, and only three cases of isolated ARCAPA in patients younger than 2 years of age have been reported. This report describes the surgical treatment of a 12-month-old girl with myocardial ischemia due to ARCAPA. The diagnosis was made by echocardiography. A reimplantation of the aberrant coronary artery was performed, and the patient had a successful postoperative course.

A symptomatic neonate with tetralogy of Fallot, an absent pulmonary valve, and a single coronary artery with a major fistula.

We present a case with a rare combination of tetralogy of Fallot with an absent pulmonary valve, and a single coronary artery with a major fistula to the main pulmonary artery. Myocardial ischemia developed in response to increasing shunt flow through the coronary fistula, resulting in heart failure. We ligated the coronary fistula and plicated the anterior wall of the dilated pulmonary arteries during the neonatal period. Complete repair through a transatrial-transpulmonary approach was performed at the age of 17 months. The postoperative course was excellent and the patient maintained a stable hemodynamic and respiratory state with no evidence of myocardial ischemia.

Bland-White-Garland syndrome with ventricular septal defect: late presentation.

Bland-White-Garland syndrome has been reported generally to occur in an isolated lesion. Here, we report a case of Bland-White-Garland syndrome associated with a ventricular septal defect. Late onset of myocardial ischemia was noted in this patient, which we think is related to increased coronary steal due to regression of pulmonary hypertension caused by narrowing of the ventricular septal defect. At surgery, we temporally occluded the left main coronary trunk to cease the coronary steal phenomenon and augment the left coronary flow. Direct implantation of the left coronary artery and closure of the ventricular septal defect were performed. The postoperative course was excellent with no evidence of myocardial ischemia.

Impact of 3-mm Blalock-Taussig shunt in neonates and infants with a functionally single ventricle.

Functionally single ventricle (f-SV) is susceptible to volume overload. Atrioventricular valve regurgitation (AVVR) tends to develop and ventricular function deteriorates due to excessive pulmonary blood flow following modified Blalock-Taussig shunt (mBTS). On the other hand, a small caliber graft has risks of early obstruction and poor growth of pulmonary vascular beds. We assessed the effect of mBTS with a 3-mm graft to circumvent volume overload in f-SV on achievement of the right heart bypass. Eleven neonates and infants with f-SV at the median age of 24 days underwent mBTS using a 3-mm graft between August 2004 and June 2007. There were no early deaths, but there was one late death. All survivors achieved bidirectional cavopulmonary shunt (BCPS) at 4.2 months after mBTS. Cardiac catheterization demonstrated sufficient growth of the pulmonary artery (pulmonary artery index, 268+/-98 cm(2)/m(2)), low pulmonary vascular resistance (1.4+/-0.9 U.m(2)). The AVVR remained mild or less. Ventricular end-diastolic volume and ejection fraction were 171+/-61% of the normal value and 64+/-6%, respectively. We conclude that a 3-mm mBTS was useful in preventing f-SV from volume overload and was effective for growing good pulmonary vasculature and achieving a right heart bypass.

Long-term results of Konno procedure for complex left ventricular outflow tract obstruction.

OBJECTIVE: The current study aims to evaluate the long-term outcomes of the Konno procedure. METHODS: The clinical records of 63 patients who had undergone the Konno procedure between February 1984 and March 2007 were reviewed. During this period, the Ross procedure was introduced in 1996. Of the 63 patients, 38 were male and 25, female. Their ages at the time of operation ranged from 1 year 9 months to 37 years, and their body weights ranged from 8.1 to 63 kg. Valves larger than 23 mm were used in 57 patients. RESULTS: There was one hospital death (myocardial infarction) and six late deaths (sudden death, 2; congestive heart failure, 2; infectious endocarditis, 1; traffic accident, 1). The Kaplan-Meier survival rates including hospital mortality and late mortality were 91.9% at 10 years and 87.7% at 15 years. There were 20 significant complications in 16 patients: thromboembolism was noted in 1 patient; reoperations (Konno procedure (aortic valve replacement), 5 (thrombosed valve, 3; pannus formation, 1; IE, 1); mitral valve replacement, 3; coronary artery bypass grafting, 2; grafting of the descending aorta, 1), balloon dilatation for recoarctation, and 7 catheter interventions were required in 9, 1, and 5 patients, respectively. The event-free rates including all events were 75.2% at 10 years and 67.2% at 15 years. In the long-term period, the results of echocardiography revealed good cardiac function. CONCLUSIONS: The Konno procedure is effective and safe for the treatment of complex left ventricular outflow tract obstruction and for the preservation of ventricular function. Since some issues concerning anticoagulation-related complications and infectious endocarditis remain, careful observation is mandatory.

[Novel coronary transfer technique for transposition of the great arteries with Planché type II coronary anatomy].

The arterial switch operation has evolved to become the treatment of choice for most of transposition of the great arteries and some types of double outlet right ventricle. Technical improvement in the coronary transfer is the major contribution to the evolution of this procedure. We proposed a novel technique of coronary transfer for the patients with rare but difficult coronary anatomy of Planché type II. We believe it could become one of the options of coronary transfer technique and contribute to the completion of arterial switch operation with uncommon coronary artery patterns.

Successful application of pulmonary arterial patch for coronary angioplasty late after arterial switch operation.

Pulmonary artery is infrequently utilized as a material for coronary patch angioplasty in children. We applied a pulmonary arterial patch for coronary angioplasty on an 8-year-old boy with total occlusion of the left main coronary artery late after an arterial switch operation. The pulmonary arterial patch was easy to handle and the immediate result after the operation was satisfactory.

Konno procedure using atrioventricular groove patch plasty after arterial switch operation.

A patient with transposition of the great arteries accompanied by Shaher type 9 coronary anatomy experienced the development of progressive neoaortic valvular regurgitation with a small annulus, supravalvular stenosis, and neopulmonary valvular and supravalvular stenoses 15 years after an arterial switch operation. To implant a prosthetic valve clinically adequate in size, the Konno procedure was necessary. However, the right coronary anatomy precluded the original Konno procedure. My colleagues and I accomplished neoaortic anterior annular enlargement in this case by using atrioventricular groove patch plasty without jeopardizing the right coronary artery, and this resulted in a satisfactory outcome.

Surgery for unilateral absence of pulmonary artery using autologous tissue.

A 7-year-old girl with unilateral absence of the pulmonary artery underwent autologous tissue limited reconstructive surgery. The proximal portion of the artery was reconstructed by rotating a reverse U-shaped cut opposite the pulmonary arterial wall and covering the anterior surface with autologous pericardium. Follow-up catheterization at 5.8 years after surgery revealed no stenosis. This procedure could become one of the preferred methods for this unusual clinical condition.

Progressive diffuse aortic stenosis after localized supravalvular aortic stenosis repair.

A 6-year-old boy presented with diffuse stenosis of the aortic arch. He had undergone patch augmentation for localized supravalvular aortic stenosis at 2 years of age. Before the initial operation, the aortic arch and descending aorta were noticed to be hypoplastic with a diameter of 60 to 73% of that of the aortic annulus, without a pressure gradient. 4 years later, progressive diffuse stenosis of the aortic arch with a diameter of 42% of that of the aortic annulus was found. Reoperation, consisting of patch augmentation of the aortic arch, was carried out. A pressure gradient of 40 mmHg distal to the repair was newly recognized, again. This is a rare case of supravalvular aortic stenosis, which required reoperation because of the progression of diffuse stenosis of the distal aorta.
