Best Practices in Managing Transition to Adulthood for Adolescents With Congenital Heart Disease: The Transition Process and Medical and Psychosocial Issues: A Scientific Statement From the American Heart Association

Many children born with complex childhood illnesses that historically caused early death are now surviving into adulthood with the expectation of leading meaningful and productive lives. They will ultimately need to transition their care from pediatric to adult-centered care. Unfortunately, in the absence of structured programs to guide this transition, there is often delayed or inappropriate care, improper timing of the transfer of care, and undue emotional and financial stress on the patients, their families, and the healthcare system. At its worst, and as frequently happens now, patients are lost to appropriate follow-up. In fact, the number of adults with congenital heart disease (CHD) in the United States is rising exponentially and now exceeds 1 000 000.1,–,7 At least half of these patients may have complex CHD. Fewer than 30% of adults with CHD are seen by appropriate specialized providers. Fewer than 15% of these patients, who are seen in specialty adult CHD (ACHD) clinics, have CHD that is classified as severe.8 Thus, adolescents with CHD constitute a growing population of individuals for whom a well-planned and well-executed “transition process” is essential. The goals of a formal transition program are to prepare young adults for transfer of care. It should provide uninterrupted health care that is patient centered, age and developmentally appropriate, flexible, and comprehensive. It should include age-appropriate education about medical conditions and promote skills in communication, decision making, self-care, and self-advocacy.9,–,13 It should foster greater personal and medical independence and a greater sense of control over health, healthcare decisions, and psychosocial environment. The ultimate goal of a transition program is to optimize the quality of life (QOL), life expectancy, and future productivity of young patients.14 We acknowledge that the development of ideal transition programs is a …

Pregnancy outcomes after the Fontan repair

OBJECTIVES This study sought to determine risks and outcome of pregnancy and delivery after the modified Fontan operation. BACKGROUND Increasingly, female Fontan patients reaching child-bearing years are interested in having children. To date, the number of reported pregnancies is small, and pregnancy has therefore been discouraged. METHODS One hundred ten of 126 female patients from the Fontan registries of the Mayo Clinic and University of California Los Angeles Medical Center responded to a mailed questionnaire. An additional six patients with a reported pregnancy from other centers were identified and reviewed to assess pregnancy outcomes. RESULTS Among the participating centers, a total of 33 pregnancies after Fontan operation for various types of univentricular heart disease were reported. There were 15 (45%) live births from 14 mothers, with 13 spontaneous abortions and 5 elective terminations. In the 14 women with live births, the median number of years between operation and pregnancy was 4 (range 2 to 14). Reported prepregnancy problems in these gravidas included atrial flutter in one patient and ventricular dysfunction, aortic regurgitation and atrioventricular valve regurgitation in another. One patient developed supraventricular tachycardia during pregnancy and had conversion to sinus rhythm. No maternal cardiac complications were reported during labor, delivery or the immediate puerperium. There were six female and nine male infants (mean gestational age 36.5 weeks; median weight 2,344 g). One infant had an atrial septal defect. At follow-up, mothers and infants were alive and well. CONCLUSIONS Pregnancy after the Fontan operation appears to have been well tolerated in 13 to 14 gravidas. There does appear to be an increased risk of miscarriage. The tendency to routinely discourage pregnancy may need to be reconsidered.

Renal function and urate metabolism in late survivors with cyanotic congenital heart disease.

Diminished glomerular filtration rate, proteinuria, and large hypercellular congested glomeruli with segmental sclerosis are found in late survivors with cyanotic congenital heart disease (CCHD). Hyperuricemia is common, acute gouty arthritis is less common than uric acid levels would predict, and overt tophaceous deposits of uric acid are exceptional. The role of the kidney in causing the basic biochemical disturbances, and the relative importance of impaired urate excretion vs urate overproduction have not been established. Accordingly, we reviewed the courses of two index patients and prospectively studied eight additional CCHD patients from 28 years to 46 years old with mean hematocrits of (62 +/- 10%). Plasma creatinine concentration was normal (0.9 +/- 0.1 mg/dl) yet glomerular filtration rate was mildly reduced to 93 +/- 14 ml/min as measured by creatinine clearance and to 81 +/- 6 ml/min as measured by 111In DTPA. Three patients had significant proteinuria and one was nephrotic. Plasma uric acid concentration was high in all but one (8.2 +/- 2.1 mg/dl), mean 24 hr uric acid excretion was normal (564 +/- 221 mg), and fractional uric acid excretion was relatively low (6.3 +/- 2.6%). The two patients with highest plasma uric acid levels (12.0 and 10.2 mg/dl) had the lowest fractional excretions (2.8% and 4.0%). Both of these patients had diminished capacity to excrete a water load (38% and 27%/4 hr) and to maximally concentrate urine (520 and 635 mOsm/kg after water deprivation and vasopressin). In conclusion, high plasma uric acid levels in late survivors with CCHD are secondary to inappropriately low fractional uric acid excretion, not to urate overproduction.(ABSTRACT TRUNCATED AT 250 WORDS)

Management of Pregnancy in Patients With Complex Congenital Heart Disease: A Scientific Statement for Healthcare Professionals From the American Heart Association

Today, most female children born with congenital heart disease will reach childbearing age. For many women with complex congenital heart disease, carrying a pregnancy carries a moderate to high risk for both the mother and her fetus. Many such women, however, do not have access to adult congenital heart disease tertiary centers with experienced reproductive programs. Therefore, it is important that all practitioners who will be managing these women have current information not only on preconception counseling and diagnostic evaluation to determine maternal and fetal risk but also on how to manage them once they are pregnant and when to refer them to a regional center with expertise in pregnancy management.

Menstrual patterns in women with congenital heart disease

To examine the extent to which congenital heart disease (CHD) influences ovarian function, 98 women (mean age 32.7 years) were asked to complete a mailed questionnaire regarding their menstrual patterns. Patients were divided into acyanotic (60%) and cyanotic (38.8%) groups. Cycle lengths, duration of menstrual cycle, regularity of menses, amount of flow, and breakthrough bleeding were compared in these two groups and against agematched controls. The mean age of menarche for the sample (13.4 years) was significantly different (p<0.004) when compared to their controls (12.5 years). With the exception of breakthrough bleeding, statistical differences were not found between the study population and the controls. When the menstrual histories of cyanotic women were compared with those of acyanotic women, differences were found for all categories of menstrual patterns with the exception of the amount of menstrual flow. Menstrual patterns of cyanotic women compared to controls were found to be significantly different for all categories with the exception of amount of flow. In general, women with CHD have menstrual patterns similar to those in the general population.

Development of an international research agenda for adult congenital heart disease nursing

Background: Since the population of adults with congenital heart disease (CHD) is growing, the role of nurse specialists is expanding. In order to advance ACHD nursing, the establishment of an international nursing research agenda is recommended. We aimed to investigate research priorities as perceived by nurse specialists and researchers in ACHD. Methods: We applied a sequential quan–qual design. In the quantitative phase, a two-round Delphi study was conducted, in which 37 nurse specialists and nurse researchers in ACHD care participated. Respondents assessed the level of priority of 21 research topics using a 9-point rating scale (1 = no priority at all; 9 = very high priority). In the qualitative phase, semi-structured interviews were performed with six selected Delphi panelists, to scrutinize pending research questions. Results: This study revealed that priority should be given to studies investigating knowledge and education of patients, outcomes of Advanced Practice Nursing, quality of life, transfer and transition, and illness experiences and psychosocial issues in adults with CHD. A low priority was given to post-operative pain, sexual functioning, transplantation in ACHD, and health care costs and utilization. Agreement about the level of priority was obtained for 14 out of 21 research topics. Conclusion: Based on this study, we could develop an international research agenda for ACHD. Researchers ought to focus on these areas of highest priority, in order to expand and strengthen the body of knowledge in ACHD nursing.

Menstrual cycle and its disorders in women with congenital heart disease.

OBJECTIVES To investigate the age at menarche, the prevalence of menstrual cycle (interval) disorders, and determinants in women with congenital heart disease (CHD). DESIGN Using two CHD registries, 1802 (82%) of the 2196 women with CHD contacted (aged 18-58 years) provided written informed consent. After exclusion of patients with genetic disorders known to be associated with menstrual cycle disorders, 1593 eligible patients remained. Interviews by telephone and reviews of medical records were conducted. RESULTS Overall, the age at menarche was slightly increased in women with CHD (13.3 vs. 13.1 years in the general population), mainly attributable to an increased prevalence of primary amenorrhea (n = 147; 9.2%). Other menstrual cycle disorders were documented: secondary amenorrhea (n = 181, 11.4%), polymenorrhea (n = 103, 6.5%), oligomenorrhea (n = 90, 5.6%), and menorrhagia (n = 117, 6.5%). The occurrence of these disorders also depended on the presence of cyanotic heart disease, surgical status, the number of surgical interventions, and the severity of CHD. DISCUSSION Menstrual cycle disturbances, in particular primary amenorrhea, were frequently observed in this population. Patients with complex (cyanotic) heart disease needing repeated surgical interventions prior to menarche are especially at risk.

PREGNANCY AFTER FONTAN OPERATION: EARLY AND LATE OUTCOMES

The Fontan procedure is the definitive operation for patients with single ventricle physiology. As more women with Fontan operations reach childbearing age, it is important to determine the impact pregnancy has on short and long-term outcomes. The purpose of this multicenter study was to determine
