ABSTRACT
Background Recognition of precapillary pulmonary hypertension (PH) has significant implications for patient management. However, the low a priori chance to find this rare condition in community hospitals may create a barrier against performing a right heart catheterization (RHC). This could result in misclassification of PH and delayed diagnosis/treatment of precapillary PH. Therefore, we investigated patient characteristics and echocardiographic parameters associated with the decision whether to perform an RHC in patients with incident PH in 12 Dutch community hospitals. Methods and Results In total, 275 patients were included from the OPTICS (Optimizing PH Diagnostic Network in Community Hospitals) registry, a prospective cohort study with patients with incident PH; 157 patients were diagnosed with RHC (34 chronic thromboembolic PH, 38 pulmonary arterial hypertension, 81 postcapillary PH, 4 miscellaneous PH), while 118 patients were labeled as probable postcapillary PH without hemodynamic confirmation. Multivariable analysis showed that older age (>60 years), left ventricular diastolic dysfunction grade 2-3, left atrial dilatation were independently associated with the decision to not perform an RHC, while presence of prior venous thromboembolic events or pulmonary arterial hypertension-associated conditions, right atrial dilatation, and tricuspid regurgitation velocity ≥3.7 m/s favor an RHC performance. Conclusions Older age and echocardiographic parameters of left heart disease were independently associated with the decision to not perform an RHC, while presence of prior venous thromboembolic events or pulmonary arterial hypertension-associated conditions, right atrial dilation, and severe PH on echocardiography favored an RHC performance. As such, especially elderly patients may be at an increased risk of diagnostic delays and missed diagnoses of treatable precapillary PH, which could lead to a worse prognosis.

BACKGROUND: Coronary artery disease (CAD) will increasingly determine outcome in the aging adult congenital heart disease (CHD) population. We aimed to determine sex-specific incidence of CAD in adult CHD patients throughout adulthood, compared to the general population. METHODS AND RESULTS: We followed 11,723 adult CHD patients (median age 33 years; 49% male; 57% mild, 34% moderate, 9% severe CHD) from the Dutch CONCOR registry, and two age-sex-matched persons per patient from the general population for first CAD event in national registers (period 2002-2012). Incidence rates were estimated using smoothed hazard functions. CAD risk during follow-up, stratified by CHD severity, was compared using proportional subdistribution hazards regression. In ACHD patients, 103 CAD events (43 women) occurred over 60,456 person-years. Rates per 1000person-years increased from 0.3(95% confidence interval: 0.1-0.6) at age 20 to 5.8(3.7-8.9) at 70 years in female, and from 0.5(0.3-1.0) to 7.8(5.1-11.8) in male patients. Compared to the general population, relative risk was 12.0(2.5-56.3) in women and 4.6(1.7-12.1) in men aged 20 years. Relative risk declined with age, remaining significant up to age ~65 years in women and ~50 years in men. In patients with mild, moderate and severe CHD, CAD risk was 1.3(0.9-1.9), 1.6(1.0-2.5) and 2.9(1.3-6.9) times increased compared to the general population, respectively. CONCLUSIONS: We found increased CAD risk in adult CHD patients, with greater relative risk at younger age, in women and those with more severe CHD. These results underline the importance of screening for and treatment of CAD risk factors in these patients.

AIM: To determine the prevalence of unidentified bicuspid aortic valve (BAV) or aortic dilatation (>40mm) in first degree relatives (FDR) of patients with isolated BAV in a general hospital. METHODS AND RESULTS: Patients with isolated BAV received information advising cardiac screening of their FDR. Referred and screened were 134 FDR of 54 adult index patients with isolated BAV (median 2 per index patient). FDR's mean age was 49years (range 16-83years) and 41% were male. They comprised 5 parents (3.7%), 52 siblings (39%) and 77 offspring (57%). Among these FDR, the prevalence of BAV was 6.0% (8 patients). In FDR without BAV, 10 (7.5%) had aortic dilatation. 'Familial BAV' was present in 9/54 families (17%). CONCLUSION: In a general hospital, screening of FDR of patients with isolated BAV resulted in a substantial yield of 13% new cases with BAV or aortic dilatation without BAV.

BACKGROUND: Congenital coronary-pulmonary fistulas (CPFs) are commonly unilateral, but bilateral and multilateral fistulas may occur. In multilateral CPFs, the value of a multidetector computed tomography (MDCT) imaging technique as an adjuvant to coronary angiography (CAG) is eminent. The purpose of this study was to describe the clinical presentation, diagnostic modalities, and management of coincidentally detected congenital CPFs. HYPOTHESIS: Unilateral and multilateral coronary-pulmonary fistulas are increasingly detected due to the wide speard application of multidetector computed tomography which might be a supplementary or replacing to conventional coronary angiography. METHODS: We evaluated 14 adult patients with congenital coronary artery fistulas (CAFs) who were identified from several Dutch cardiology departments. RESULTS: Fourteen adult patients (5 female and 9 male), with a mean age of 57.5 years (range, 24-80 years) had the following abnormal findings: audible systolic cardiac murmur (n = 4), chronic atrial fibrillation (n = 2), nonsustained ventricular tachycardia (n = 1), and cardiomegaly on chest x-ray (n = 2). Echocardiography revealed normal findings with trivial valvular abnormalities (n = 9), depressed left ventricle systolic function (n = 3), and severe mitral regurgitation and atrial dilatation (n = 2). The findings in the rest of the patients were unremarkable. CAG and MDCT were used as a diagnostic imaging techniques either alone (CAG, n = 6; MDCT, n = 1) or in combination (n = 7). Single modality and multimodality diagnostic methods revealed 22 fistulas including CPFs (n = 15), coronary cameral fistulas terminating into the right (n = 2) and the left atrium (n = 1), and systemic-pulmonary fistulas (n = 4). Of all of the fistulas, 10 were unilateral, 6 were bilateral, and 6 was hexalateral. (13) N-ammonia positron emission tomography-computed tomography was performed in 3 patients revealing decreased myocardial perfusion reserve. CONCLUSIONS: CAG remains the gold standard for detection of CPFs. An adjuvant technique using MDCT provides full anatomical details of the fistulas.
