Quality of life of adult Fontan patients.

BACKGROUND: Progress in the management of complex congenital heart disease (CHD) led to an improvement in survival rates of adults with a Fontan-like circulation. The objective of this study was to assess the subjective health status and quality of life of this population. METHODS AND RESULTS: Patients aged more than 18 years at the time of the study, who underwent a Fontan-like procedure. Subjective health status was assessed by the SF-36 questionnaire and a linear analog scale was used to score patients' self-perception of their quality of life; cardiac and demographic parameters were collected. RESULTS: Among 65 eligible patients, 60 (23 females; mean ± SD age: 25.7 ± 7.2 years) answered the SF-36 questionnaire and 46 of these were interviewed to evaluate their perceived quality of life. Among them, 20 (33.3%) were working full-time and 21 (35%) experienced arrhythmias. The physical SF-36 scores were lower in patients than in the general population (p ≤ 0.05). The New York Hear Association (NYHA) class and occupation were correlated with SF-36 scores of physical activity (respectively, p = 0.0001 and p = 0.025). SF-36 scores of psychological status were associated with the number of drugs and occupation (respectively, p = 0.0001 and p = 0.02). The mean ± SD quality of life score measured using a linear analog scale was 7.02 ± 1.6 and was linked to education and occupation (p ≤ 0.05) but not with cardiac parameters. CONCLUSION: Adult Fontan patients perceive an impaired physical health but report a good overall quality of life. Education and occupation impacts significantly on Fontan patients' quality of life.

Total Anomalous Pulmonary Venous Connection: A 40 years' Experience Analysis.

Background Total anomalous pulmonary venous connection is a rare cardiac malformation associated with significant morbidity and mortality rates. We report a large surgical series study to evaluate mid-term and long-term results of conventional surgical techniques. Methods and Results We performed a retrospective analytic study of all patients operated on for simple total anomalous pulmonary venous connection in the University Hospital of Lyon, France, between January 1973 and June 2014. A total of 180 patients were included (43% supracardiac, 27% intracardiac, 19% infracardiac, and 11% mixed types). Mean cardiopulmonary bypass and aortic cross clamp times were respectively 66 and 39 minutes. Overall mortality was 27.1%, including 38 early deaths (21.1%) and 12 late deaths (6.1%). The percentage of early death greatly decreased over the eras, from 42.1% in the seventies to 7.4% after 2010. Besides the earlier era of intervention (p < 0.0001), significant risk factors for death in multivariate analysis were preoperative pulmonary hypertension, acidosis, and cardiopulmonary bypass time. There were 24 reoperations, including 7 for pulmonary venous obstruction; 6 died. Factors directly and independently associated with late complications were the anatomic type (mixed forms, p = 0.0023), and length of aortic cross clamp time (p = 0.01). Long-term results for survivals are excellent. We report 84.7% of asymptomatic patients with a mean follow-up of 10.8 years. Conclusions The overall prognosis of total anomalous pulmonary venous connection repair with conventional procedures has greatly improved over the years with excellent long-term results. A thorough evaluation of all preoperative characteristics is imperative to achieve the best outcome.

Is a severe preoperative condition a contraindication for aortic valve-sparing reimplantation in type A aortic dissection?

BACKGROUND: Type A aortic dissection (TAAD) surgical management is still under debate. The purpose of this study was to demonstrate the feasibility and safety of the aortic valve-sparing root reconstruction (AVSR) procedure in 92 consecutive patients operated for TAAD, even when preoperative condition was severe (malperfusion, shock or both). METHODS: Our hospital database was reviewed to identify all patients who underwent an AVSR procedure for TAAD over 14 years. From May 2000 to June 2014, 92 consecutive patients were studied regarding to their preoperative condition. RESULTS: Age (61±13 years) and logistic Euroscore (23.4±15.3%) as well as cross-clamping (113±39 min), cardiopulmonary bypass (142±49 min) and circulatory arrest (22±13 min) times were collected. Hospital mortality was 16.3%. Mean follow-up was complete for a mean period of 27.6 months. One patient had early reoperation for aortic insufficiency. Actuarial survival at 1 year was 82.5%. The analysis of each group showed comparable mortality and morbidity in between patients. CONCLUSIONS: Based upon our experience in the management of TAAD, a reimplantation procedure could be performed regardless preoperative malperfusion or shock, with an acceptable postoperative over mortality or morbidity. A word of caution should be brought to patients over 70 years old.

Focus on echocardiographic and Doppler analysis of coronary artery abnormal origin from the pulmonary trunk with mild myocardial dysfunction.

BACKGROUND: Late presentation of abnormal origin of coronary artery from the pulmonary artery (ACAPA) is uncommon compared with early presentation, which usually induces extended myocardial necrosis and severe heart failure. The late presentation is characterized by abundant development of intercoronary collaterals resulting in mild and rare symptoms, but nevertheless can cause sudden cardiac death. Our objective was to describe presentation, cardiovascular imaging methods for diagnosis and outcomes of patients with late presentation of ACAP. METHODS: The study is a retrospective review of a single-center database to identify all patients diagnosed with ACAPA beyond the first year of life. RESULTS: From 1976 to 2011, 10 patients were identified with ACAPA at the age of 1.1-64 years: 6 with left coronary artery from the pulmonary artery (ALCAPA) and 4 with right coronary artery from the pulmonary artery (ARCAPA). Echocardiography and Doppler imaging evidenced: (1) direct signs: the abnormal coronary ostium arising from the pulmonary trunk with retrograde coronary artery flow and (2) indirect signs: abundant intercoronary septal collaterals with anterograde flow (ARCAPA) or retrograde flow (ALCAPA) and dilatation of the controlateral normally originated coronary artery. Nine patients underwent surgical implantation of the ACAPA into the ascending aorta. After 7.9 years mean follow-up, all were asymptomatic except one who required a second surgery. CONCLUSIONS: Noninvasive cardiovascular imaging, namely transthoracic echocardiography and Doppler specific parameters, can reach diagnosis of late presentation of ACAPA. Direct aortic implantation is a reliable and effective to establish dual coronary artery circulation and prevent risks due to myocardial ischemia.

Bilateral renal artery stenosis and epidermal nevus syndrome in a child.

Epidermal nevus syndrome is a rare congenital sporadic neuro-ectodermic disorder, characterized by the presence of epidermal nevi in association with various developmental abnormalities of the skin, eyes, nervous, skeletal, cardiovascular and urogenital systems. We describe a 5-year-old boy with conjunctival lipodermoid, cervical and facial sebaceous nevi who presented at 3 years of age with hypertension due to bilateral renal artery stenosis together with multiple vascular anomalies (aorta, celiac trunk, superior mesenteric artery) as shown by magnetic resonance angiography. Systemic arterial hypertension was difficult to control despite combined anti-hypertensive drugs and the surgical repair of the aortic coarctation.

Direct Reimplantation Procedure in Anomalous Aortic Origin of the Right Coronary Artery: Long-Term Single Center Outcomes.

BACKGROUND: Anomalous aortic origin of the right coronary artery is known to be a cause of sudden cardiac death in athletes. There are no specific guidelines concerning treatment strategy in the literature. The aim of this study is to describe and report our experience of direct reimplantation technique in the treatment of this anomaly. METHODS: This was a retrospective single center study of 30 patients who underwent surgery in the congenital heart disease unit of Louis Pradel Heart and Lung Hospital between January 2003 and December 2016. The mean follow-up was seven years (3 months-17 years). RESULTS: Thirty patients underwent surgery. The median age was 17 years (0.2-52 years). There were 24 males. The median weight was 58 kg (3.6-118 kg). Fourteen patients were actively engaged in sports. Twenty-six patients had exertional chest pain or syncope. The median time lapse between diagnosis and intervention was 4.5 months (0.5-179 months). Twenty-seven (90%) patients underwent reimplantation of the anomalous coronary artery without transverse aortotomy, while in 3 (10%) patients transverse aortotomy was used to facilitate reimplantation to avoid tension at the anastomosis. There was no early death; one late death occurred in the third postoperative month. At the last follow-up, all patients had returned to normal physical activity without evidence of ischemia. CONCLUSIONS: Direct reimplantation allows for a complete restoration of the coronary anatomy and enables patients to return to normal physical activity. Our study shows encouraging results using a direct reimplantation technique without aortotomy.

Diagnosis and treatment of anomalous aortic origin of coronary artery: A twenty-year retrospective study of experience and decision-making in children and young adults.

BACKGROUND: Anomalous aortic origin of a coronary artery, particularly in the presence of inter-arterial course between the great arteries, has been found to be associated with sudden death in young people. METHODS: This study reports a single-center experience in the management of anomalous aortic origin of a coronary artery, with or without inter-arterial course, by focusing specifically on presentation, diagnosis, and patient outcome. RESULTS: From March 1993 to February 2018, 100 patients (70 males) were diagnosed with anomalous aortic origin of a coronary artery, including 27 left coronary artery from the right sinus, 60 right coronary artery from the left sinus, and 13 other anomalies. Patients with inter-arterial course between the great arteries presented more frequently with syncope and/or sudden death compared to patients without (23.4% vs. 0%, p = 0.026). Diagnosis was reached using first-line transthoracic echocardiography in 65% of cases. Surgical repair was performed in 61 patients (61%). All operated patients (60 direct implantations, 1 unroofing) had been diagnosed with inter-arterial course between the great arteries, and were asymptomatic at a mean (±SD) postoperative follow-up of 4.9 ± 5.3 years. CONCLUSIONS: An inter-arterial course of the anomalous right or left coronary arteries arising from the opposite sinus is associated with life-threatening events. Direct reimplantation of coronary artery is reliable, and should be discussed even in asymptomatic patients.

Congenital native interruption of aortic arch in an adult: extra-anatomic approach by right-side thoracotomy.

We outline the case of an 18-year-old male patient with a congenital nonoperated interruption of the aortic arch. A right thoracotomy without cardiopulmonary bypass facilitated repair through an extra-anatomic bypass between the ascending and the supradiaphragmatic descending aorta. Results for the immediate and 2-year radiologic and clinical check-up were satisfactory. The most common complications in anatomic correction are stroke under selective cerebral perfusion, risk of paraplegia, and hemorrhage. We present a new technique for repair of interruption of the aortic arch in adults that avoids the need for extended dissection of the aorta and a partial occlusion clamp during anastomosis and allows for cerebral and medullar perfusion.

Correction of Tetralogy of Fallot Associated With Anomalous Coronary Artery Without Extracardiac Conduit.

Between 1983 and 2016, we operated on 14 children with tetralogy of Fallot with an anomalous coronary artery crossing the pulmonary infundibulum, which is an anomaly that makes the repair complex. The technique used was the enlargement of the right ventricular outflow tract underneath the mobilized coronary artery. All patients had right ventricular outflow tract relief without coronary artery injury. Only one patient required the use of an extracardiac conduit. There was neither in-hospital mortality nor coronary anomaly requiring reintervention. Mobilizing the anomalous coronary artery in tetralogy of Fallot repair often allows relief of obstruction without using an extracardiac conduit.

Coronary artery bypass in myocardial ischemia of the young due to hydatid cyst.

Cardiac hydatid cyst is an uncommon disease, especially in France. It is rarely responsible for myocardial ischemia, and even more rarely in the young. We report the clinical features and imaging of a 24-year-old Tunisian woman with hydatid cyst of the free wall of the left ventricle responsible for myocardial ischemia, associated with a hepatic hydatid cyst. Management consisted of a combination of surgery with cystopericystectomy and coronary artery bypass graft and prolonged medical treatment as for treatment of hepatic hydatid cyst. Three-year follow-up revealed no recurrence. This case illustrates two interesting points: the rare clinical presentation of cardiac hydatid cyst with a coronary syndrome in a young 24-year-old woman related to compression of the left anterior descending artery by the cyst with a need for coronary artery bypass graft after resection of the cyst, and the value of medical treatment of hydatid disease, even for cardiac localization.

Time course and prognostic value of plasma B-type natriuretic peptide concentration in neonates undergoing the arterial switch operation.

BACKGROUND: Plasma B-type natriuretic peptide (BNP) can predict postoperative complications after cardiac surgery in adults. Our aim was to investigate BNP kinetics and prognostic value in neonates undergoing the arterial switch operation (ASO) for transposition of the great arteries (TGA). METHODS: We measured BNP concentrations in 30 neonates before, immediately after, and 6, 12, 24, and 48 h after ASO for TGA. Complicated postoperative evolution was defined as patients requiring mechanical ventilation or presenting low cardiac output syndrome for more than 72 h. We studied the ability of postoperative BNP concentrations to predict complicated evolution. RESULTS: Intubation duration, inotropic support duration, and intensive care unit stay were 68 (48-121) h, 78 (69-141) h, and 96 (76-149) h respectively. Patients with complicated evolution had higher 6 and 12-h BNP concentrations than patients with simple evolution (459 (210-897) vs 137 (67-248) ng/L and 547 (193-868) vs 185 (79-354) ng/L respectively; P < 0.05) and had longer intubation, inotropic support, and intensive care unit stay (96 (70-190) vs 50 (48-66) h, 100 (83-190) vs 70 (59-72) h, and 120 (90-240) vs 84 (72-96) h, P < 0.05). A 6-h BNP concentration >160 ng/L was able to predict complicated evolution with a sensitivity of 93% and a specificity of 67%. CONCLUSION: In neonates, BNP concentrations can predict adverse outcome in the postoperative period after ASO for TGA. This marker has potential clinical applications.

Surgical repair of a pseudocoarctation with cervical aortic arch complicated by multiple aneurysms of the aorta: a case report.

Aortic pseudocoarctation is a rare congenital anomaly characterized by elongation and deformity of the aortic arch and is known to be associated with aneurysmal formation. Several studies unite to say it leads to a surgical sanction as soon as symptomatic or associated with aneurysms of the aortic arch. Our patient is a 12 years old boy, followed since birth for a little tight pseudocoarctation with a cervical aortic arch and transverse aortic arch hypoplasia. Close clinical and paraclinical monitoring including angioscans, showed the gradual enlargement of the superior mediastinum, in relation with the appearance of three aneurysms of the aortic arch. The intervention, performed by sternotomy, has consisted of the resection of the aneurysmal area and the interposition of a Dacron tube to repair the aortic arch and the reimplantation of the left subclavian artery into the left carotid artery. The postoperative course was uneventful. Management of pseudocoarctation associated with cervical aortic arch and aneurysms remains surgical. Close monitoring of patients with pseudocorctation, seems to be essential to avoid fatal complications such as aneurysmal rupture.

Reimplantation of left coronary artery from pulmonary artery in a 65-year-old.

Anomalous left coronary artery to the pulmonary artery is a rare pathology with a mortality rate of 90% in the first year of life, directly related to left ventricular function and coronary perfusion, although several adult cases have been reported. Surgical correction consists of ligation of the anomalous left coronary artery associated with coronary artery bypass grafting. We describe the exceptional case of a 65-year-old woman who underwent reimplantation of the left coronary artery in the anatomical position without bridging.

Surgical ablation of atrial fibrillation with off-pump, epicardial, high-intensity focused ultrasound: results of a multicenter trial.

BACKGROUND: A simplified alternative to the Cox maze procedure to treat atrial fibrillation with epicardial high-intensity focused ultrasound was evaluated clinically, and the initial clinical results were assessed at the 6-month follow-up visit. METHODS: From September 2002 through February 2004, 103 patients were prospectively enrolled in a multicenter study. Atrial fibrillation duration ranged from 6 to 240 months (mean, 44 months) and was permanent in 76 (74%) patients, paroxysmal in 22 (21%) patients, and persistent in 5 (5%) patients. All patients had concomitant operations, and ablation was performed epicardially on the beating heart before the concomitant procedure. The device automatically created a circumferential left atrial ablation around the pulmonary veins in an average of 10 minutes, and an additional mitral line was created epicardially in 35 (34%) patients with a handheld device by using the same technology. RESULTS: No complications or deaths were device or procedure related. There were 4 (3.8%) early deaths and 2 late extracardiac deaths. The 6-month follow-up was complete in all survivors. At the 6-month visit, freedom from atrial fibrillation was 85% in the entire study group (80% in patients with permanent atrial fibrillation, 88% in the 35 patients who had the additional mitral line, and 100% in patients with paroxysmal atrial fibrillation). A pacemaker was implanted in 8 patients. Only the duration and type of atrial fibrillation significantly increased the risk of recurrence. CONCLUSION: Epicardial, off-pump, beating-heart ablation with acoustic energy is safe and cures 80% of patients with permanent atrial fibrillation associated with long-standing structural heart disease.

Atypical forms of isolated partial atrioventricular septal defect increase the risk of initial valve replacement and reoperation.

OBJECTIVE: We consider the short- and long-term outcomes of the repair of the isolated partial atrioventricular (AV) septal defect to determine the role played by the atypical forms on the initial AV valve replacement and on the risk of reoperation. METHODS: Two hundred and eight patients underwent an operation for this malformation between 1974 and 2001. Clinical and echocardiographic examinations were performed on all patients, the AV valve regurgitation was graded from 1 to 4 and a residual interatrial shunt was sought. Median age at the intervention was 5.8 years (3 months to 67 years). RESULTS: Median follow-up time was 7.5 years (range 0-22.6 years). The cumulative 30-day, 5- and 20-year survival rates were 96.5, 95.4 and 94.6%, respectively. AV valve replacement was associated with a high mortality (P<0.001). A reoperation was performed on 12 patients (5.7%) including six patients within less than a 30-day period, especially to repair residual AV valve regurgitation. We performed four AV valve repairs by annuloplasty and six AV valve replacements. Two patients who had initially undergone an AV valve replacement underwent a reoperation for valve thrombosis. The cumulative 30-day, 5- and 20-year rates of freedom from reoperation were 96.5, 93.6 and 83%, respectively. An atypical form was present in 24 patients (11.5%) and was a risk factor for initial AV valve replacement (P<0.001) and for reoperation (P<0.001). A complete AV block occurred in 13 patients (6.2%), all of them within a 30-day period. The AV valve replacement was a high risk factor for a complete AV block (P<0.001). At the end of our study 180 patients (96%) were in NYHA I and 8 in NYHA II. CONCLUSIONS: The morbi-mortality of the isolated partial AV septal defect is primarily perioperative and is linked with the presence of an atypical form of the lesion. This atypical form was the main reason for reoperation for AV valve regurgitation. The AV valve replacement was associated with a high mortality and with the occurrence of complete AV block. Using a standardized technique, the AV septal defect can be repaired with excellent long-term clinical and echographic results.

Rabbit antithymocyte globulin as induction immunotherapy in pediatric heart transplantation.

BACKGROUND: There is little published data on the use of antithymocyte globulins in children. This retrospective study describes the use of Thymoglobulin (Imtix, SangStat, Lyon, France) in pediatric cardiac transplantation over a 13-year period in a single center that adjusted the dose of Thymoglobulin according to platelet count monitoring and examines the short-term hematological effects as well as longer-term outcomes. METHODS: Data for all children who received a heart transplant at the Hôpital Cardiologique at Lyon from 1984 to 2001 and who were given Thymoglobulin as part of their immunosuppressive protocol were extracted. The dose of Thymoglobulin given depended on baseline platelet count and was 2, 1.5, or 1 mg/kg per day over 5 days for the following platelet count groups: greater than 150,000/mm (normal group), 100 to 150,000/mm (mild thrombocytopenia group), and 50 to 100,000/mm (moderate thrombocytopenia group). RESULTS: Thirty children of median age 14.2 years were given a median cumulative dose of Thymoglobulin of 8 mg/kg per patient; the moderate thrombocytopenia subgroup was given significantly less (6.4 mg/kg) ( P=0.032). Immediate tolerability of Thymoglobulin was good, with no cases of first-dose syndrome, anaphylaxis, or serum sickness. The platelet count decreased at the start of therapy, but recovered after discontinuation, and did not give rise to clinical concern. Patients were followed up for a median of 6.3 years (7 days-15.5 years); actuarial survival was 90%, 86%, and 74.5%, respectively, at 1, 5, and 10 years. In the first year, 50% of patients suffered an episode of rejection. The overall incidence of infection in the month following transplantation was 40%. One lymphoma occurred at 5 months. CONCLUSIONS: The use of Thymoglobulin in pediatric heart-transplant patients as part of an immunosuppressive protocol, with dose adjustment according to platelet levels, has been shown to be effective in terms of rejection rate and patient survival and safe in terms of the incidence of infections and malignancy.

Changing management of cardiac myxoma based on a series of 40 cases with long-term follow-up.

BACKGROUND: Cardiac myxoma is generally considered to be a surgical emergency. However, as a result of progress in echocardiography and the increasing age of the patients presenting with this disease, the clinical presentation has changed and the management of cardiac myxoma now needs to be reviewed. METHODS: Between 1978 and 2001, 40 patients (16 men and 24 women) between the ages of 6 months and 82 years (mean age, 55.6 years) were operated on for cardiac myxoma. Signs of heart failure with pulmonary congestion (22%) or pulmonary embolism (20%) indicated a high-risk emergency situation in some cases, whereas, in other cases (58%), the patient's condition was stable and the clinical presentation was less worrying. However, the tumor was always removed within 24 hours of admission. Most cases of cardiac myxoma observed over the last decade correspond to stable forms, as echocardiography has revealed smaller tumors in generally elderly patients. RESULTS: The postoperative mortality was 7.5% (3 patients). No patients were lost to follow-up, and the mean follow-up was 13.6 years. One patient was reoperated for recurrence 3 years postoperatively. Five patients required further cardiac surgery: three mitral valve replacements, one coronary artery bypass graft, and one angioplasty. The 15-year survival rate was 69%. CONCLUSIONS: Myxoma tends to be observed in a more elderly and higher risk population, often at an early stage. The classic approach of emergency surgery is not always appropriate in these stable forms, allowing more thorough preoperative assessment of these patients.

Repair of atrial septal defect through a limited right anterolateral thoracotomy in 242 patients: a cosmetic approach?

BACKGROUND: The repair of atrial septal defects (ASD) is often safely performed as a routine procedure in the young and asymptomatic patient. The purpose of this study is to evaluate the feasibility and especially the cosmetic result of this repair performed through a limited right anterolateral thoracotomy (RALT), with the complete cannulation and aortic cross-clamping conducted through the same incision. METHODS: From January 1980 to June 2001 in our hospital, 242 patients (210 female) with atrial septal defects and a mean age of 26.2 +/- 12.0 years underwent operations through a RALT. Repaired defects included 235 ostium secundum defects and 7 sinus venosus defects with partial anomalous pulmonary venous connection (SV). Patients were contacted by phone to evaluate their satisfaction with the thoracic scar. RESULTS: There was neither operative nor early mortality. All of the mentioned defects were successfully corrected. Mean bypass times were 12.37 +/- 4.9 minutes for ASD defects and 47.5 +/- 6.4 minutes for SV defects. The mean stay in the intensive care unit was 1.3 +/- 0.5 days. Most of the patients (86.3%) were fully satisfied with the cosmetic result. CONCLUSIONS: The right anterolateral thoracotomy incision provides a safe and effective approach for the correction of the ASD. This approach can be safely performed without any new instruments and without peripheral incisions, provides good exposure for the surgeon to work comfortably, and achieves a cosmetically superior result in selected cases.

Potential interest of a new absorbable collagen membrane in the prevention of adhesions in paediatric cardiac surgery: a feasibility study.

BACKGROUND: Open-heart surgery can result in adhesions, which can complicate resternotomy. AIMS: To document the occurrence of adhesions after the use of a new collagen membrane; to evaluate its tolerability; and to compare surgical parameters with control patients. METHODS: Paediatric patients who underwent cardiac surgery with the collagen membrane (Cova™ CARD; Biom'up, Saint Priest, France) were analysed retrospectively for levels of adhesion and tolerability. The times of dissection and intervention and the transfusion of packed red blood cells and haemostatic products were compared to a historic cohort who did not receive an anti-adhesion device. RESULTS: From January 2010 to December 2011, 36 patients received a collagen membrane. Nineteen re-interventions were performed, after a mean of 169 days. No grade 3 adhesions were observed and no tolerability problems were reported. During re-interventions after more than 30 days, the propensity score-adjusted durations of dissection and the total process for patients with and without a collagen membrane were 32 vs 41 minutes and 151 vs 182 minutes, respectively (not significant). The mean quantities of red blood cells and biological glue administered in the two groups were 98 vs 139 mL and 1.2 vs 0.5 mL, respectively (not significant). CONCLUSIONS: This feasibility study shows the potential use of the new membrane in paediatric patients, both in terms of prevention from severe adherence and tolerability. This is the first study of this membrane in humans. A prospective, controlled study is necessary to provide strong evidence of its efficiency.
