Depression and anxiety in adult congenital heart disease: Predictors and prevalence

BACKGROUND Adult congenital heart disease (ACHD) patients face unique medical and social challenges that may contribute to psychological difficulties. The goals of this study were to identify predictors of symptoms of depression and anxiety and evaluate the prevalence of mood and anxiety disorders among North American ACHD patients. METHODS In this cross-sectional study, consecutive patients were recruited from two ACHD outpatient clinics. All patients completed self-report psychosocial measures and a subset was randomly selected to participate in structured clinical interviews. Linear regression models were used to predict symptoms of depression and anxiety. RESULTS A total of 280 patients (mean age=32 years; 52% female) completed self-report measures. Sixty percent had defects of moderate complexity and 31% had defects of great complexity. Significant predictors of depressive symptoms were loneliness (p<0.001), perceived health status (p<0.001), and fear of negative evaluation (p=0.02). Predictors of anxiety symptoms were loneliness (p<0.001) and fear of negative evaluation (p<0.001). Disease severity and functional class did not predict mood or anxiety symptoms. Fifty percent of interviewed patients (29/58) met diagnostic criteria for at least one lifetime mood or anxiety disorder, of whom 39% had never received any mental health treatment. CONCLUSIONS The results confirm an increased risk and under-treatment of mood and anxiety disorders in ACHD patients. Social adjustment and patient-perceived health status were more predictive of depression and anxiety than medical variables. These factors are modifiable and therefore a potential focus of intervention.

Pregnancy and Contraception in Congenital Heart Disease: What Women Are Not Told

As increased numbers of patients with congenital heart disease (CHD) survive to adulthood more women with CHD are reaching reproductive age. Contraception and pregnancy have now become important issues in this population; however both can be associated with increased risks in women with CHD (1). Other issues such as adverse fetal outcomes in these women and transmission of CHD to offspring must be addressed. Current guidelines for the care of adults with CHD recommend proactive counseling regarding issues of contraception and pregnancy (2-5). The objective of this study was to evaluate whether women with CHD have adequate knowledge regarding risks of contraception and pregnancy. (authors)

Adults with congenital heart disease: psychological needs and treatment preferences.

OBJECTIVE Approximately one-third of adult congenital heart disease (ACHD) patients have mood or anxiety disorders, the majority of which go untreated. The extent to which this group of patients is interested in psychological services is, however, unknown. This study investigated the perceived psychological needs of patients and their mental health treatment preferences. DESIGN Participants completed an anonymous survey with items regarding mental health treatment history, preferences for future treatment, Internet use, and interest in peer support. RESULTS A total of 155 ACHD patients completed study questionnaires (mean age = 39 years; 50% female). Forty percent of patients reported previous mental health treatment. Some 51% of patients (73/142) indicated significant interest in at least 1 of 7 defined areas of psychological treatment (managing mood and/or anxiety, coping with a cardiac condition, stress management, anger management, relationship difficulties, substance use, and smoking cessation). Patients were most interested in stress management and coping with heart disease; one-third of patients (48/141 and 47/141, respectively) expressed high interest in these 2 topics. There was a consistent preference for psychological treatment to be provided over the Internet vs. in person or over the telephone; 94% of the patients had Internet access. In total, 35% of patients (51/145) were interested in receiving peer support. CONCLUSIONS It is not only health providers who recognize the importance of psychological care for ACHD patients. As a group, patients are also interested in psychological treatment and peer support. Programs are encouraged to provide psychological services and maximize opportunities for interactions with other patients.

Stenosis of the superior limb of the systemic venous baffle following a Mustard procedure: An under-recognized problem

BACKGROUND Patients with atrioventricular concordance and ventriculoarterial discordance (DTGA) and a Mustard procedure may develop stenosis of the superior limb of the systemic venous baffle (SLSVB). The frequency of this complication in an adult cohort was evaluated. METHODS Patients >18 years with DTGA and a Mustard procedure with and without a pacemaker (PM)/implantable cardioverter defibrillator (ICD) were identified through an institutional database. Subjects were included following a cardiac imaging study (computed tomography, magnetic resonance imaging, venography or cardiac catheterization) and follow-up in the PM/ICD or congenital cardiac clinics from 2001 to 2007. The primary end-point was narrowing of the SLSVB (<10mm) on cardiac imaging. Hemodynamically significant narrowing was defined by: azygous vein dilatation with retrograde flow or superior vena cava syndrome or the need for dilatation ± stenting of the SLSVB. RESULTS Narrowing of the SLSVB was observed in 49/112 patients (70 males) age 31 ± 6 years (range 18-49) and was hemodynamically significant in 15/49. Of 29 patients with a PM (23) or ICD (6) and cardiac imaging, 17 had narrowing of the SLSVB which was hemodynamically significant in 8. Non-echocardiographic imaging had a sensitivity of 88% at detecting narrowing of the SLSVB in contrast to pulse-wave Doppler, which yielded a sensitivity of 16% (61% negative predictive value, 88% positive predictive value). CONCLUSIONS In our adult cohort of Mustard patients, narrowing of the SLSVB had a prevalence of 44% and was more likely to be detected by non-echocardiographic imaging. Baffle patency should be evaluated before transvenous device implantation.

Prevalence and Determinants of Anemia in Adults With Complex Congenital Heart Disease and Ventricular Dysfunction (Subaortic Right Ventricle and Single Ventricle Physiology)

Anemia is well recognized as a marker of poor prognosis in patients with acquired heart disease and heart failure. Adults with complex congenital heart disease and ventricular dysfunction (subaortic right ventricle or single-ventricle physiology) represent a different population, because they are typically much younger and have less co-morbidity compared with patients with acquired forms of heart disease. The purpose of this study was to evaluate the prevalence and determinants of anemia in this population. Baseline hemoglobin levels were recorded at the time of the initial clinic visit, and final hemoglobin levels were those recorded before death or transplantation or at study completion. Anemia was defined as hemoglobin <135 g/L in men and <120 g/L in women. One hundred sixty-seven patients (100 men, mean age 34 +/- 8 years, mean ejection fraction 35 +/- 9%) were included, 66 with atrial switch operations, 42 with congenitally corrected transposition of the great arteries, and 59 with Fontan physiology. The mean hemoglobin level at baseline was 149 +/- 22 g/L and at follow-up was 139 +/- 29 g/L. The overall prevalence of anemia was 29% at completion. Hyponatremia, decreased renal function, and the use of warfarin were independent predictors of anemia. In conclusion, anemia is common in patients with complex congenital heart disease and ventricular dysfunction, in particular those with Fontan physiology.

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.
