Adults with congenital heart disease: what every cardiologist should know about their care.

As patients with congenital heart disease (CHD) continue to enjoy longer lives, non-congenital cardiologists and other healthcare professionals are increasingly encountering them in their practice and are challenged by their specific needs. Most under- and post-graduate medical training tends to overlook this common pathology, resulting in insufficient awareness of post-repair or post-palliation residual lesions and sequelae from previous interventions. In a strive towards improving the quality of care for this ever-growing cardiovascular patient cohort, it is prudent to outline the areas of concern and specific management needs pertaining to adult patients with CHD and share it with non-CHD professionals. The purpose of this paper is to offer essential guidance to physicians, including cardiologists, when they encounter a patient with CHD in a non-congenital healthcare setting.

A new score for life-threatening ventricular arrhythmias and sudden cardiac death in adults with transposition of the great arteries and a systemic right ventricle.

AIMS: To investigate the incidence of major adverse ventricular arrhythmias and related events (MAREs) and to develop a stratification tool predicting MAREs in adults with a systemic right ventricle (sRV). METHODS AND RESULTS: In a multicentre approach, all adults (≥16 years old) with a sRV undergoing follow-up between 2000 and 2018 were identified. The incidence of MAREs, defined as sudden cardiac death, sustained ventricular tachycardia, and appropriate implantable cardioverter-defibrillator (ICD) therapy, was analysed. The association of MAREs with clinical, electrical, and echocardiographic parameters was evaluated. A total of 1184 patients (median age 27.1 years; interquartile range 19.9-34.9 years; 59% male; 70% with atrial switch repair for D-transposition of the great arteries) were included. The incidence of MAREs was 6.3 per 1000 patient-years. On multivariate analysis, age, history of heart failure, syncope, QRS duration, severe sRV dysfunction and at least moderate left ventricular outflow tract obstruction were retained in the final model with a C-index of 0.78 [95% confidence interval (CI) 0.72-0.83] and a calibration slope of 0.93 (95% CI 0.64-1.21). For every five ICDs implanted in patients with a 5-year MARE risk >10%, one patient may potentially be spared from a MARE. CONCLUSION: Sudden cardiac death remains a devastating cause of death in a contemporary adult cohort with a sRV. A prediction model based on clinical, electrocardiographic, and echocardiographic parameters was devised to estimate MARE risk and to identify high-risk patients who may benefit from primary prevention ICD implantation.

Predictors of Death in Contemporary Adult Patients With Eisenmenger Syndrome: A Multicenter Study.

BACKGROUND: Eisenmenger syndrome is associated with substantial morbidity and mortality. There is no consensus, however, on mortality risk stratification. We aimed to investigate survival and predictors of death in a large, contemporary cohort of Eisenmenger syndrome patients. METHODS: In a multicenter approach, we identified adults with Eisenmenger syndrome under follow-up between 2000 and 2015. We examined survival and its association with clinical, electrocardiographic, echocardiographic, and laboratory parameters. RESULTS: We studied 1098 patients (median age, 34.4 years; range, 16.1-84.4 years; 65.1% female; 31.9% with Down syndrome). The majority had a posttricuspid defect (n=643, 58.6%), followed by patients with a complex (n=315, 28.7%) and pretricuspid lesion (n=140, 12.7%). Over a median follow-up of 3.1 years (interquartile range, 1.4-5.9), allowing for 4361.6 patient-years observation, 278 patients died and 6 underwent transplantation. Twelve parameters emerged as significant predictors of death on univariable analysis. On multivariable Cox regression analysis, only age (hazard ratio [HR], 1.41/10 years; 95% confidence interval [CI], 1.24-1.59; P<0.001), pretricuspid shunt (HR, 1.56; 95% CI, 1.02-2.39; P=0.041), oxygen saturation at rest (HR, 0.53/10%; 95% CI, 0.43-0.65; P<0.001), presence of sinus rhythm (HR, 0.53; 95% CI, 0.32-0.88; P=0.013), and presence of pericardial effusion (HR, 2.41; 95% CI, 1.59-3.66; P<0.001) remained significant predictors of death. CONCLUSIONS: There is significant premature mortality among contemporary adults with Eisenmenger syndrome. We report, herewith, a multivariable mortality risk stratification model based on 5 simple, noninvasive predictors of death in this population.

Past and current cause-specific mortality in Eisenmenger syndrome.

AIMS: Eisenmenger syndrome (ES) is associated with considerable morbidity and mortality. Therapeutic strategies have changed during the 2000s in conjunction with an emphasis on specialist follow-up. The aim of this study was to determine the cause-specific mortality in ES and evaluate any relevant changes between 1977 and 2015. METHODS AND RESULTS: This is a retrospective, descriptive multicentre study. A total of 1546 patients (mean age 38.7 ± 15.4 years; 36% male) from 13 countries were included. Cause-specific mortality was examined before and after July 2006, 'early' and 'late', respectively. Over a median follow-up of 6.1 years (interquartile range 2.1-21.5 years) 558 deaths were recorded; cause-specific mortality was identified in 411 (74%) cases. Leading causes of death were heart failure (34%), infection (26%), sudden cardiac death (10%), thromboembolism (8%), haemorrhage (7%), and peri-procedural (7%). Heart failure deaths increased in the 'late' relative to the 'early' era (P = 0.032), whereas death from thromboembolic events and death in relation to cardiac and non-cardiac procedures decreased (P = 0.014, P = 0.014, P = 0.004, respectively). There was an increase in longevity in the 'late' vs. 'early' era (median survival 52.3 vs. 35.2 years, P < 0.001). CONCLUSION: The study shows that despite changes in therapy, care, and follow-up of ES in tertiary care centres, all-cause mortality including cardiac remains high. Patients from the 'late' era, however, die later and from chronic rather than acute cardiac causes, primarily heart failure, whereas peri-procedural and deaths due to haemoptysis have become less common. Lifelong vigilance in tertiary centres and further research for ES are clearly needed.

Cardiovascular autonomic dysfunction and carotid stiffness in adults with repaired tetralogy of Fallot.

PURPOSE: Adults after surgical repair of tetralogy of Fallot (ToF) may have impaired vascular and cardiac autonomic function. Thus, we wanted to assess interrelations between heart rate variability (HRV) and heart rate recovery (HRR), as parameters of cardiac autonomic function, and arterial stiffness, as a parameter of vascular function, in adults with repaired ToF as compared to healthy controls. METHODS: In a case-control study of adults with repaired ToF and healthy age-matched controls we measured: 5-min HRV variability (with time and frequency domain data collected), carotid artery stiffness (through pulse-wave analysis using echo-tracking ultrasound) and post-exercise HRR (cycle ergometer exercise testing). RESULTS: Twenty-five patients with repaired ToF (mean age 38 ± 10 years) and 10 healthy controls (mean age 39 ± 8 years) were included. Selected HRR and HRV (time-domain) parameters, but not arterial stiffness were significantly reduced in adults after ToF repair. Moreover, a strong association between late/slow HRR (after 2, 3 and 4 min) and carotid artery stiffness was detected in ToF patients (r = -0.404, p = 0.045; r = -0.545, p = 0.005 and r = -0.545, p = 0.005, respectively), with statistical significance retained even after adjusting for age, gender, resting heart rate and ß-blockers use (r = -0.393, p = 0.024 for HRR after 3 min). CONCLUSION: Autonomic cardiac function is impaired in patients with repaired ToF, and independently associated with vascular function in adults after ToF repair, but not in age-matched healthy controls. These results might help in introducing new predictors of cardiovascular morbidity in a growing population of adults after surgical repair of ToF.

Coronary Artery Embolism From a Blood Cyst of the Mitral Valve.

Blood cysts are benign, congenital tumours of the heart endothelium, found most commonly on heart valves. Adult cases are rare, since most spontaneously regress with age. However, reports of symptomatic cases with embolic phenomena and valve dysfunction have been described. We present a case of a previously healthy 44-year-old woman with no cardiovascular risk factors who developed acute myocardial infarction caused by coronary artery embolism from a blood cyst of the anterior mitral valve leaflet.

Exercise-induced hypertension after aortic coarctation repair: Our experience and a systematic review.

BACKGROUND: The exact prevalence and clinical significance of excessive increase in blood pressure in response to exercise in patients with repaired coarctation of aorta (CoA) remains unknown. AIM: This study aimed to investigate the impact of different definitions of exercise-induced hypertension (EIH) on the prevalence rates in our adult patients with repaired CoA. A systematic review of the available literature was also performed. METHODS: We retrospectively analyzed exercise test data from adult patients with repaired CoA followed at the national referral center for adult congenital heart disease between 1998 and 2021. The three most reported definitions of EIH in patients with repaired CoA were used for the analysis of EIH prevalence. We also performed a systematic search of the PubMed electronic bibliographic database. Full-text versions of all potentially relevant articles on EIH in CoA were reviewed for relevance. RESULTS: Our registry included 161 adult CoA patients. Complete exercise test results were available in 74 patients (59% male, median age 39 years [range 20-68 years]). The prevalence of EIH in our cohort varied from 24 to 41%, depending on the definition used. We identified eleven eligible articles from 184 publications. The reported prevalence rate of EIH in the studies ranged from 13% to 82%. CONCLUSION: EIH is common in patients with repaired CoA; however, the rates of EIH vary greatly depending on the definition used. A standardized and uniform EIH definition is needed to accurately assess the prevalence and clinical relevance of EIH in this population.

One-minute sit-to-stand test in patients with pulmonary arterial hypertension associated with congenital heart disease: A single-center prospective study.

BACKGROUND: Patients with pulmonary arterial hypertension associated with congenital heart disease (PAH-CHD) have reduced exercise capacity. Recently, the 1-minute sit-to-stand test (1MSTST), which measures the number of repetitions from sitting to standing position in 1 minute, has been proposed as an alternative test to the 6-minute walking test (6MWT). The aim of our study was to assess the safety and results of the 1MSTST in comparison to the 6MWT in patients with PAH-CHD. METHODS: Consecutive adult patients with PAH-CHD underwent the 6MWT and the 1MSTST on the same day. The 6-minute walking distance in meters and the number of repetitions on the 1MSTST were measured. Heart rate, peripheral oxygen saturations, Borg dyspnea score, and lower limb fatigue were recorded before and immediately after testing. Correlations between both tests and clinical, laboratory, and imaging parameters were statistically analyzed. RESULTS: The study included 40 patients (50% female, mean age 43 ± 15 years), of whom 29 (72%) had Eisenmenger syndrome and 14 (35%) had Down syndrome. The number of 1MSTST repetitions correlated significantly with 6MWT distance (r = 0.807, p = 0.000). There were no adverse events, and the 1MSTST results correlated with the WHO functional class. Heart rate increase and oxygen desaturation after both tests correlated significantly, but less desaturation was observed after 1MSTST. CONCLUSIONS: Our study showed that the 1MSTST is a safe and easily applicable test in adult patients with PAH-CHD, including patients with Down syndrome. The results of the 1MSTST correlate significantly with the 6MWT, providing an alternative tool for exercise capacity assessment in patients with PAH-CHD.

ACE Inhibitor and Angiotensin Receptor Blocker Use During Pregnancy: Data From the ESC Registry Of Pregnancy and Cardiac Disease (ROPAC).

Angiotensin-converting enzyme inhibitors (ACE-Is) and angiotensin receptor blockers (ARBs) are not recommended during the second and third trimester because of the significant risk of congenital anomalies associated with their use. However, data are scarce, especially regarding their use in the first trimester and about the impact of stopping just before pregnancy. Our study illustrates the profile of the women who used ACE-Is or ARBs during pregnancy and evaluates the impact on perinatal outcomes. The Registry of Pregnancy and Cardiac Disease is a prospective, global registry of pregnancies in women with structural heart disease. Outcomes were compared between women who used ACE-Is or ARBs and those who did not. Multivariable regression analysis was performed to assess the effect of ACE-I or ARB use on the occurrence of congenital anomalies. ACE-Is (n = 35) and/or ARBs (n = 8) were used in 42 (0.7%) of the 5,739 Registry of Pregnancy and Cardiac Disease pregnancies. Women who used ACE-Is or ARBs more often came from a low-or-middle-income country (57% vs 40%, p = 0.021), had chronic hypertension (31% vs 6%, p <0.001), or a left ventricular ejection fraction <40% (33% vs 4%, p <0.001). In the multivariable analysis, ACE-I use during the first trimester was associated with an increased risk of congenital anomaly (odds ratio 3.2, 95% confidence interval 1.0 to 9.6). Therefore, ACE-Is should be avoided during pregnancy, also in the first trimester, because of a higher risk of congenital anomalies. However, there is no need to stop long before pregnancy. Preconception counseling is crucial to discuss the potential risks of these medications, to evaluate the clinical condition and, if possible, to change or stop the medication.

External Validation of a Risk Score Model for Predicting Major Clinical Events in Adults After Atrial Switch.

BACKGROUND: A risk model has been proposed to provide a patient individualized estimation of risk for major clinical events (heart failure events, ventricular arrhythmia, all-cause mortality) in patients with transposition of the great arteries and atrial switch surgery. We aimed to externally validate the model. METHODS AND RESULTS: A retrospective, multicentric, longitudinal cohort of 417 patients with transposition of the great arteries (median age, 24 years at baseline [interquartile range, 18-30]; 63% men) independent of the model development and internal validation cohort was studied. The performance of the prediction model in predicting risk at 5 years was assessed, and additional predictors of major clinical events were evaluated separately in our cohort. Twenty-five patients (5.9%) met the major clinical events end point within 5 years. Model validation showed good discrimination between high and low 5-year risk patients (Harrell C index of 0.73 [95% CI, 0.65-0.81]) but tended to overestimate this risk (calibration slope of 0.20 [95% CI, 0.03-0.36]). In our population, the strongest independent predictors of major clinical events were a history of heart failure and at least mild impairment of the subpulmonary left ventricle function. CONCLUSIONS: We reported the first external validation of a major clinical events risk model in a large cohort of adults with transposition of the great arteries. The model allows for distinguishing patients at low risk from those at intermediate to high risk. Previous episode of heart failure and subpulmonary left ventricle dysfunction appear to be key markers in the prognosis of patients. Further optimizing risk models are needed to individualize risk predictions in patients with transposition of the great arteries.

The association between myocardial ischemia and myocardial dysfunction in adult patients with systemic right ventricle - A single centre multimodality study.

BACKGROUND: The exact interaction of factors leading to myocardial dysfunction and fibrosis of the systemic right ventricle (SRV) is not completely understood. Myocardial ischemia and injury associated with a supply-demand mismatch of the pressure overloaded SRV are thought to play an important role, however studies confirming this are lacking. METHODS: Adult SRV patients were included in this single centre cohort study. All patients underwent a comprehensive diagnostic and imaging workup. A two-day stress-rest SPECT was performed to assess myocardial perfusion. SRV ischemia was defined as decreased segmental tracer uptake during exercise with significant improvement at rest. Contrast enhanced cardiac magnetic resonance imaging (CMR) was also performed in a subgroup of patients without contraindication, to assess focal myocardial fibrosis. Differences between patients with and without SRV ischemia were assessed. RESULTS: Twenty-three SRV patients (15 with transposition of the great arteries after atrial switch procedure and 8 with congenitally corrected transposition of the great arteries; 5 (22%) females; mean age 38 ± 11 years) were included. Seven (30%) patients had SRV ischemia on SPECT. Late gadolinium enhancement on CMR was more common in patients with SRV ischemia (p = 0.002). However, there was no association between SRV ischemia and different echocardiographic or CMR parameters of SRV systolic function, laboratory markers (high-sensitivity troponin I and NT-proBNP) and exercise capacity. CONCLUSIONS: Our multimodality study showed that SRV ischemia in adult SRV patients was associated with more focal myocardial fibrosis, but not with functional or imaging markers of SRV function.

Infective endocarditis in adults with congenital heart disease: Contemporary management and related outcomes in Central and South-Eastern European region.

BACKGROUND: Infective endocarditis (IE) remains major cause of morbidity and mortality in adult congenital heart disease (ACHD). Limited data exists on ACHD with IE in Central and South-Eastern European (CESEE) countries. The aim of this study is to characterize contemporary management and assess outcomes of ACHD with IE in CESEE region. METHODS: Data on ACHD patients with IE from 9 tertiary centres in 9 different CESEE countries between 2015 and 2020 was included. Baseline demographics, clinical presentation, indication for surgery, outcomes, hospital and all-cause-1-year mortality were studied. RESULTS: A total of 295 ACHD patients (mean age 40 ± 14 years) with IE were included. Median time from symptoms onset to establishing diagnosis was 25 (11-59) days. The majority of patients (203, 68.8%) received previous empiric oral antibiotic therapy. The highest incidence of IE was observed on native and left sided valves, 194(65.8%) and 204(69.2%), respectively. More than half had a vegetation size ≥10 mm (164, 55.6%); overall 138 (46.8%) had valve complications and 119 (40.3%) had heart failure. In-hospital mortality was 26 (8.8%). CONCLUSION: There is clear delay in establishing IE diagnosis amongst ACHD patients in CESEE countries. Adequate diagnosis is hampered by common prescription of empiric antibiotics before establishing formal diagnosis. Hence, patients commonly present with associated complications requiring surgery. Hospital treatment and survival are, nevertheless, comparable to other Western European countries. Improved awareness and education of patients and medical profession regarding IE preventive measures, risks, signs, and symptoms are urgently needed. Empiric antibiotic prescription before blood cultures are taken must be omitted.

Adult congenital heart disease training in Europe: current status, disparities and potential solutions.

OBJECTIVES: This study aimed to determine the status of training of adult congenital heart disease (ACHD) cardiologists in Europe. METHODS: A questionnaire was sent to ACHD cardiologists from 34 European countries. RESULTS: Representatives from 31 of 34 countries (91%) responded. ACHD cardiology was recognised by the respective ministry of Health in two countries (7%) as a subspecialty. Two countries (7%) have formally recognised ACHD training programmes, 15 (48%) have informal (neither accredited nor certified) training and 14 (45%) have very limited or no programme. Twenty-five countries (81%) described training ACHD doctors 'on the job'. The median number of ACHD centres per country was 4 (range 0-28), median number of ACHD surgical centres was 3 (0-26) and the median number of ACHD training centres was 2 (range 0-28). An established exit examination in ACHD was conducted in only one country (3%) and formal certification provided by two countries (7%). ACHD cardiologist number versus gross domestic product Pearson correlation coefficient=0.789 (p<0.001). CONCLUSION: Formal or accredited training in ACHD is rare among European countries. Many countries have very limited or no training and resort to 'train people on the job'. Few countries provide either an exit examination or certification. Efforts to harmonise training and establish standards in exit examination and certification may improve training and consequently promote the alignment of high-quality patient care.

Cardiac myxoma: single tertiary centre experience.

BACKGROUND: Although cardiac myxoma (CM) are rare and benign, they can cause life-threatening complications, such as hemodynamic disturbances or embolization. Surgical excision of the tumour is the treatment of choice. The aim of the study was to evaluate the epidemiological characteristics, clinical presentation, imaging findings, and outcomes of surgical treatment of patients with CM treated in the largest tertiary care centre in Slovenia. PATIENTS AND METHODS: We retrospectively analysed the medical records of all patients referred to our institution between January 2005 and December 2020 and identified 39 consecutive adult patients with pathologically confirmed CM. RESULTS: The average annual incidence of CM in the study was 3 per 2 million population per year. Patients were more often female (n = 25, 64%). The mean age at diagnosis was 63.1 ± 13.6 years. Dyspnoea was the most common presenting symptom (31%). CM was an incidental finding in 11 patients (28%). Seven patients presented with thromboembolic event (18%). Transthoracic echocardiography (TTE) was performed in all patients, however additional imaging was required in 22 patients (56%). All patients in our series were successfully treated surgically without in-hospital mortality. During the follow-up period (6 months to 16 years) three patients (8%) died, and all deaths were unrelated to CM. There was no recurrence of CM during the follow-up. CONCLUSIONS: Our single-centre study confirms that CM is rare cardiac tumour with diverse clinical presentation. Our data shows data that CM might be more prevalent than considered before. Surgical resection of the tumour is safe with excellent short- and long-term outcomes.

Comparison of plasma metanephrines in patients with cyanotic and acyanotic congenital heart disease.

PURPOSE: The co-occurrence of cyanotic congenital heart disease (CCHD) and PHEO/PGL has been reported, but the role of the hypoxic environment in the pathogenesis of PHEO/PGL remains unclear. Our aim was to compare plasma metanephrine and normetanephrine levels between patients with CCHD and patients with acyanotic congenital heart disease (ACCHD). METHODS: We performed a cross-sectional study in a prospective cohort of 44 patients with congenital heart disease (CHD) (31 (70.5%) females) with a median age of 37.5 (31.0-55.6) years at the time of evaluation. Thirty-two (73%) patients had CCHD and 12 (27%) patients had ACCHD. Morning blood samples for plasma determination of metanephrine and normetanephrine were collected. RESULTS: Plasma normetanephrine levels were significantly higher in patients with CCHD compared to ACCHD (p = 0.002). Ten (31.3%) patients with CCHD had plasma normetanephrine levels elevated above the reference range, while all ACCHD patients had normal levels. Patients with lower oxygen saturation and higher proBNP had significantly higher normetanephrine levels (ρ = -0.444, p = 0.003 and ρ = 0.449, p = 0.002, respectively). No chromaffin cell tumors were detected. CONCLUSION: Increased plasma normetanephrine levels in patients with CCHD can be explained by the effect of hypoxia. Future research is needed to better understand the impact of chronic hypoxia in CCHD on increased sympathetic outflow, hyperplastic response of chromaffin tissue, and the role of somatic mutations in CCHD-PHEO/PGL pathogenesis related to hypoxia.

European Society of Cardiology Working Group on Adult Congenital Heart Disease and Study Group for Adult Congenital Heart Care in Central and South Eastern European Countries consensus paper: current status, provision gaps and investment required.

AIMS: To examine the current status of care and needs of adult congenital heart disease (ACHD) services in the Central and South Eastern European (CESEE) region. METHODS AND RESULTS: We obtained data regarding the national ACHD status for 19 CESEE countries from their ACHD representative based on an extensive survey for 2017 and/or 2018. Thirteen countries reported at least one tertiary ACHD centre with a median year of centre establishment in 2007 (interquartile range 2002-2013). ACHD centres reported a median of 2114 patients under active follow-up with an annual cardiac catheter and surgical intervention volume of 49 and 40, respectively. The majority (90%) of catheter or surgical interventions were funded by government reimbursement schemes. However, all 19 countries had financial caps on a hospital level, leading to patient waiting lists and restrictions in the number of procedures that can be performed. The median number of ACHD specialists per country was 3. The majority of centres (75%) did not have ACHD specialist nurses. The six countries with no dedicated ACHD centres had lower Gross Domestic Product per capita compared to the remainder (P = 0.005). CONCLUSION: The majority of countries in CESEE now have established ACHD services with adequate infrastructure and a patient workload comparable to the rest of Europe, but important gaps still exist. ACHD care is challenged or compromised by limited financial resources, insufficient staffing levels, and reimbursement caps on essential procedures compared to Western Europe. Active advocacy and increased resources are required to address the inequalities of care across the continent.

Women leaders in Cardiology. Contemporary profile of the WHO European region.

Aims: Women's participation is steadily growing in medical schools, but they are still not sufficiently represented in cardiology, particularly in cardiology leadership positions. We present the contemporary distribution of women leaders in cardiology departments in the World Health Organization European region. Methods and results: Between August and December 2020, we applied purposive sampling to collect data and analyse gender distribution of heads of cardiology department in university/third level hospitals in 23 countries: Austria, Azerbaijan, Belgium, Bosnia-Herzegovina, Croatia, France, Germany, Greece, Italy, North Macedonia, Morocco, Poland, Portugal, Russia, Serbia, Slovakia, Slovenia, Spain, Switzerland, Tunisia, Turkey, Ukraine, and the UK. Age, cardiology subspecialty, and number of scientific publications were recorded for a subgroup of cardiology leaders for whom data were available. A total of 849 cardiology departments were analysed. Women leaders were only 30% (254/849) and were younger than their men counterpart (♀ 52.2 ± 7.7 years old vs. ♂ 58.1 ± 7.6 years old, P = 0.00001). Most women leaders were non-interventional experts (♀ 82% vs. ♂ 46%, P < 0.00001) and had significantly fewer scientific publications than men {♀ 16 [interquartile range (IQR) 2-41] publications vs. ♂ 44 (IQR 9-175) publications, P < 0.00001}. Conclusion: Across the World Health Organization European region, there is a significant gender disparity in cardiology leadership positions. Fostering a diverse and inclusive workplace is a priority to achieve the full potential and leverage the full talents of both women and men.

Dynamic changes in cardiac function before and early postdelivery in women with severe preeclampsia.

OBJECTIVES: In women with severe preeclampsia the period immediately before and early postdelivery carries the greatest risk for cardiac decompensation due to acute changes in loading conditions. The authors aimed to evaluate dynamic changes in hemodynamic and echocardiographic-derived systolic and diastolic function parameters in preeclamptic women compared with healthy controls. METHODS: Thirty women with severe preeclampsia and 30 healthy controls underwent transthoracic echocardiography 1 day before, 1 and 4 days postdelivery. Fluid responsiveness was assessed by passive leg raising. RESULTS: Peak systolic myocardial velocities (s') and global longitudinal strain (GLS) were significantly lower in preeclamptic group compared with controls only postdelivery (s': 7.3 ±â€Š0.8 vs. 8.3 ±â€Š0.9 cm/s, P < 0.001; GLS: -21.4 ±â€Š2.0 vs. -23.0 ±â€Š1.4%, P = 0.027). In addition, significant decrease in s' after delivery was observed only in preeclamptic group (P = 0.004). For diastolic parameters there were differences both before and postdelivery in E/e' ratio (before: 8.4 ±â€Š2.16 vs. 6.7 ±â€Š1.89, P = 0.002; postdelivery: 8.3 ±â€Š1.64 vs. 6.8 ±â€Š1.27, P = 0.003) and mitral e' velocity (before: 11.0 ±â€Š2.39 vs. 12.6 ±â€Š1.86, P = 0.004; postdelivery: 11.1 ±â€Š2.28 vs. 14.0 ±â€Š2.40 cm/s, P < 0.001). Significant increase in left ventricular stroke volume (P = 0.005) and transmitral E velocity (P = 0.003) was observed only in control group, reflecting response to volume load after delivery. Accordingly, only the minority of preeclamptic women were fluid responsive (11 vs. 43%, P = 0.014 between groups). CONCLUSION: Variations in cardiac parameters in healthy women seem to follow changes in loading conditions before and early after delivery. Different pattern in preeclamptic women, however, may be related to subtle myocardial dysfunction, that becomes uncovered with augmented volume load in early postpartum period.
