Editorial to: Baseline MDCT findings after prosthetic heart valve implantation provide important complementary information to echocardiography for follow-up purposes by Suchá et al.
Over the last years a growing number of prosthetic heart valve (PHV) implantation procedures have been performed in sequence with the aging of the population and improving surgical techniques. Currently, echocardiography is the most important tool in the follow-up and evaluation of complications associated with the PHV (pannus, thrombus, endocarditis). However, echocardiographic examination of PHV associated disease may be hampered by poor acoustic window or scatter artefacts caused by the PHV. PHV related disease such as endocarditis is related with a poor prognosis, especially when complications such as periannular abcess formation occurs. Early treatment of PHV associated disease improves prognosis. Therefore, an unmet clinical need for early detection of complications exists. In the evaluation of PHV (dys)function, multidetector-row computed tomography (MDCT) has shown to be of additive value. A necessity for MDCT to be implemented in daily practice is to be able to distinguish between normal and pathological features. Key Points • Early detection of PHV related complications improves prognosis • MDCT has additive value to echocardiography in the evaluation of PHV • RCTs for MDCT evaluation of PHV are required for clinical implementation.

Review
Doppler echocardiography is being used increasingly in the follow-up of patients with valvular heart prostheses because it provides unique hemodynamic information about flow through prosthetic valves. A baseline checkup about 3 months after implantation is now recommended. We therefore now supply each patient with an identity and follow-up card for each particular prosthesis.

Review
Over 4 million people worldwide have received a prosthetic heart valve, and an estimated 300,000 valves are being implanted every year. Prosthetic heart valves improve quality of life and survival of patients with severe valvular heart disease, but the need for antithrombotic therapy to prevent thrombotic complications in valve recipients poses challenges for clinicians and patients. Here, we review antithrombotic therapies for patients with prosthetic heart valves and management of thromboembolic complications. Advances in antithrombotic therapy and valve technologies are likely to improve the management of patients with prosthetic heart valves in developed countries, but the most important unmet need and potential for benefit from these new therapies is in developing countries where a massive and rapidly increasing burden of valvular heart disease exists.

AIM
To study the prevalence and structure of postoperative cerebral dysfunction depending on the type and position of the implanted prosthetic heart valve in patients who underwent surgery for the acquired heart valve disease.
MATERIAL AND METHODS
The study included 115 patients (70 men and 45 women; 64 [56; 72] years old), who underwent elective replacement or repair surgery for the acquired heart valve disease.
RESULTS AND CONCLUSION
The postoperative cerebral dysfunction was diagnosed in 40.9% patients, including replacement in the aortic position (45.5%), in the mitral position (55%), in several positions (20%). Replacement surgery was accompanied by three clinical types of postoperative cerebral dysfunction and repair surgery - by deferred cognitive impairment only. Postoperative cerebral dysfunction after the replacement in the mitral position was more common (odds ratio 4.47, 95% confidence interval 1.21-18.35, p=0.041), including its acute clinical types - perioperative stroke and symptomatic delirium of the early postoperative period (p=0.029), compared to that after the repair heart valve surgery. After the replacement in the aortic position, acute clinical types of postoperative cerebral dysfunction were more common (p=0.036). After the replacement with biological prosthesis, symptomatic delirium of the early postoperative period was more common (p=0.047). The occurrence of the deferred cognitive impairment didn't depend on the type and position of the implanted prosthetic heart valve.

BACKGROUND
As the prognosis of women with prosthetic heart valves improves, an increasing number are contemplating and undertaking pregnancy. Accurate knowledge of perinatal outcomes is essential, assisting counseling and guiding care. The aims of this study were to assess outcomes in a contemporary population of women with heart valve prostheses undertaking pregnancy and to compare outcomes for women with mechanical and bioprosthetic prostheses.
METHODS AND RESULTS
Longitudinally linked population health data sets containing birth and hospital admissions data were obtained for all women giving birth in New South Wales, Australia, 2000-2011. This included information identifying presence of maternal prosthetic heart valve. Cardiovascular and birth outcomes were evaluated. Among 1 144 156 pregnancies, 136 involved women with a heart valve prosthesis (1 per 10 000). No maternal mortality was seen among these women, although the relative risk for an adverse event was higher than the general population, including severe maternal morbidity (139 versus 14 per 1000 births, rate ratio [RR]=9.96, 95% CI 6.32 to 15.7), major maternal cardiovascular event (44 versus 1 per 1000, RR 34.6, 95% CI 14.6 to 81.6), preterm birth (183 versus 66 per 1000, RR=2.77, 95% CI 1.88 to 4.07), and small-for-gestational-age infants (193 versus 95 per 1000, RR=2.03, 95% CI 1.40 to 2.96). There was a trend toward increased maternal and perinatal morbidity in women with a mechanical valve compared with those with a bioprosthetic valve.
CONCLUSIONS
Pregnancies in women with a prosthetic heart valve demonstrate an increased risk of an adverse outcome, for both mothers and infants, compared with pregnancies in the absence of heart valve prostheses. In this contemporary population, the risk was lower than previously reported.
