Review
BACKGROUND
Right ventricular failure (RVF) in patients with a continuous-flow left ventricle assist device (CF-LVAD) is associated with higher incidence of mortality. This systematic review aims to assess the overall proportion of RVF and the pre-operative echocardiographic parameters which are best correlating to RVF.
METHODS
A systematic research was conducted between 2008 and 2019 on MEDLINE, EMBASE, PUBMED, UPTODATE, OVID, COCHRANE LIBRARY, and Google Scholar electronic databases by performing a PRISMA flowchart. All observational studies regarding echocardiographic predictors of RVF in patients undergoing CF-LVAD implantation were included.
RESULTS
A total number of 19 observational human studies published between 2008 and 2019 were included. We identified 524 RVF patients out of a pooled final population of 1741 patients. The RVF overall proportion was 28.25% with 95% confidence interval (CI) 0.24-0.34. The highest variability of perioperative echocardiographic parameters between the RVF and no right ventricular failure (NO-RVF) groups has been found with tricuspid annular plane systolic excursion (TAPSE), fractional area change (FAC), and right ventricular global longitudinal strain (RVGLS). Their standardized mean deviation (SMD) was - 0.33 (95% CI - 0.54 to - 0.11; value 0.003), - 0.34 (95% CI - 0.53 to - 0.15; value 0.0001), and 0.52 (95% CI 0.79 to 0.25; value 0.0001), respectively.
CONCLUSIONS
The echocardiographic predictors of RVF after CF-LVAD placement are still uncertain. However, there seems to be a trend of statistical correlation between TAPSE, FAC, and RVGLS with RVF event after CF-LVAD placement.

INTRODUCTION AND OBJECTIVES
Echocardiography guidelines suggest normalizing left ventricular (LV) volumes and mass (LVM) to body size. During pregnancy, continuous weight variation impacts on body surface area (BSA) calculation, limiting the longitudinal analysis of cardiac remodeling (CR) and reverse remodeling (RR) variables. Our aim was to identify the most common indexing methodologies in the literature on pregnant populations through a systematic review; and, to compare four scaling methods: (i) none (absolute values); (ii) indexing to the BSA before pregnancy; (iii) allomeric indexing; and (iv) indexing to BSA measured at the same day of cardiac assessment, using an illustrative example.
METHODS
We performed a systematic review of CR and RR during pregnancy and post-partum, using two databases. We included studies reporting longitudinal echocardiographic analysis of cardiac chamber volumes in humans. We used a prospective cohort study of healthy pregnant women who underwent four echocardiographic evaluations during pregnancy and postpartum, as an illustrative example.
RESULTS
Twenty-seven studies were included, most studies indexed to BSA measured at each evaluation moment (n=21). Within-subjects design was the most reported to analyse longitudinal data (n=17). Indexation to the pre-pregnancy BSA or application of allometric indexes revealed a higher effect than BSA measured at each evaluation and an equal effect to not indexing using within-subjects design. The within-subjects designs also revealed a higher effect size value than the between-subjects design for longitudinal analysis of LVM adaptations during pregnancy and postpartum.
CONCLUSION(S)
This study concludes that indexation methods do not impact the clinical interpretation of longitudinal echocardiographic assessment but highlights the need to harmonize normalization procedures during pregnancy.

Meta-Analysis
BACKGROUND
Patients with a transposition of the great arteries (TGA) and a systemic right ventricle are at risk of heart failure (HF) development, arrhythmia and early mortality. Prognostic evaluations in clinical studies are hampered by small sample sizes and single-centred approaches. We aimed to investigate yearly rate of outcome and factors affecting it.
METHODS
A systematic literature search of four electronic databases (PubMed, EMBASE, Web of Science and Scopus) was conducted from inception to June 2022. Studies reporting the association of a systemic right ventricle with mortality with a minimal follow-up of 2 years during adulthood were selected. Incidence of HF hospitalization and/or arrhythmia were captured as additional endpoints. For each outcome, a summary effect estimate was calculated.
RESULTS
From a total of 3891 identified records, 56 studies met the selection criteria. These studies described the follow-up (on average 7.27 years) of 5358 systemic right ventricle patients. The mortality incidence was 1.3 (1-1.7) per 100 patients/year. The incidence of HF hospitalization was 2.6 (1.9-3.7) per 100 patients/year. Predictors of poor outcome were a lower left ventricular (LV) and right ventricular ejection fraction (RVEF) (standardized mean differences (SMD) of -0.43 (-0.77 to -0.09) and - 0.85 (-1.35 to -0.35), respectively), higher plasma concentrations of NT-proBNP (SMD of 1.24 (0.49-1.99)), and NYHA class ≥2 (risk ratio of 2.17 (1.40-3.35)).
CONCLUSIONS
TGA patients with a systemic right ventricle have increased incidence of mortality and HF hospitalization. A lower LVEF and RVEF, higher levels of NT-proBNP and NYHA class ≥2 are associated with poor outcome.

Meta-Analysis Review
PURPOSE
Perioperative pulmonary hypertension (PH) is an independent risk factor for morbidity and mortality in cardiac surgery. While inhaled prostacyclins (iPGIs) are an established treatment of chronic PH, data on the efficacy of iPGIs in perioperative PH are scarce.
METHODS
We searched PubMed, Embase, the Web of Science, CENTRAL, and the grey literature from inception until April 2021. We included randomized controlled trials investigating the use of iPGIs in adult and pediatric patients undergoing cardiac surgery with an increased risk of perioperative right ventricle failure. We assessed the efficacy and safety of iPGIs compared with placebo and other inhaled or intravenous vasodilators with random-effect meta-analyses. The primary outcome was mean pulmonary artery pressure (MPAP). Secondary outcomes included other hemodynamic parameters and mortality.
RESULTS
Thirteen studies were included, comprising 734 patients. Inhaled prostacyclins significantly decreased MPAP compared with placebo (standardized effect size, 0.46; 95% confidence interval [CI], 0.11 to 0.87; P = 0.01) and to intravenous vasodilators (1.26; 95% CI, 0.03 to 2.49; P = 0.045). Inhaled prostacyclins significantly improved the cardiac index compared with intravenous vasodilators (1.53; 95% CI, 0.50 to 2.57; P = 0.004). In contrast, mean arterial pressure was significantly lower in patients treated with iPGIs vs placebo (-0.39; 95% CI, -0.62 to 0.16; P = 0.001), but higher than in patients treated with intravenous vasodilators (0.81; 95% CI, 0.29 to 1.33; P = 0.002). With respect to hemodynamics, iPGIs had similar effects as other inhaled vasodilators. Mortality was not affected by iPGIs.
CONCLUSION
The results of this systematic review and meta-analysis show that iPGIs improved pulmonary hemodynamics with similar efficacy as other inhaled vasodilators, but caused a significant small decrease in arterial pressure when compared with placebo, indicating spill-over into the systemic circulation. These effects did not affect clinical outcomes.

Review
Cardiac magnetic resonance (CMR) four-dimensional (4D) flow is a novel method for flow quantification potentially helpful in management of mitral valve regurgitation (MVR). In this systematic review, we aimed to depict the clinical role of intraventricular 4D-flow in MVR. The reproducibility, technical aspects, and comparison against conventional techniques were evaluated. Published studies on SCOPUS, MEDLINE, and EMBASE were included using search terms on 4D-flow CMR in MVR. Out of 420 screened articles, 18 studies fulfilled our inclusion criteria. All studies (n = 18, 100%) assessed MVR using 4D-flow intraventricular annular inflow (4D-flow) method, which calculates the regurgitation by subtracting the aortic forward flow from the mitral forward flow. Thereof, 4D-flow jet quantification (4D-flow) was assessed in 5 (28%), standard 2D phase-contrast (2D-PC) flow imaging in 8 (44%) and the volumetric method (the deviation of left ventricle stroke volume and right ventricular stroke volume) in 2 (11%) studies. Inter-method correlations among the 4 MVR quantification methods were heterogeneous across studies, ranging from moderate to excellent correlations. Two studies compared 4D-flow to echocardiography with moderate correlation. In 12 (63%) studies the reproducibility of 4D-flow techniques in quantifying MVR was studied. Thereof, 9 (75%) studies investigated the reproducibility of the 4D-flow method and the majority (n = 7, 78%) reported good to excellent intra- and inter-reader reproducibility. Intraventricular 4D-flow provides high reproducibility with heterogeneous correlations to conventional quantification methods. Due to the absence of a gold standard and unknown accuracies, future longitudinal outcome studies are needed to assess the clinical value of 4D-flow in the clinical setting of MVR.

Review
PURPOSE
Catheter-directed therapy has been increasingly used in acute pulmonary embolism (PE). Whether ultrasound-assisted thrombolysis (USAT) is superior to standard catheter-directed thrombolysis (SCDT) remains unclear. This is a systemic review and meta-analysis of comparative trials on USAT and SCDT for PE to determine whether either modality yielded better clinical efficacy and safety.
MATERIALS AND METHOD
Major databases including PubMed, Embase, Cochrane Central, and Web of Science were searched through March 16, 2023. Studies that reported outcomes of SCDT and USAT for acute PE were included. Studies reported data on therapeutic efficacy (a reduction in the right ventricle [RV]/left ventricle [LV] ratio, a reduction in the systolic pulmonary artery pressure [mm Hg], change in Miller index, length of intensive care unit [ICU] and hospital stay) and safety outcomes (in-hospital mortality, overall and major bleeding events).
RESULTS
A total of 9 studies with 2610 patients were included in the meta-analysis. The analysis showed significantly greater improvement in the RV/LV ratio in the SCDT group than in the USAT group (mean difference [MD]: -0.155; 95% confidence interval [CI]: -0.249 to -0.006). No statistically significant differences were found between groups comparing change in systolic pulmonary artery pressure (MD: 0.592 mm Hg; 95% CI: -2.623 to 3.807), change in Miller index (MD: -4.1%; 95% CI: -9.5 to 1.3%), hospital stay (MD: 0.372 days; 95% CI: -0.972 to 1.717), and ICU stay (MD: -0.073.038 days; 95% CI: -1.184 to 1). No significant difference was noted in safety outcomes, including in-hospital mortality (pooled odds ratio: 0.984; 95% CI: 0.597 to 1.622), and major bleeding (pooled odds ratio: 1.162; 95% CI: 0.714 to 1.894).
CONCLUSIONS
In our meta-analysis of observational and randomized studies, USAT is not superior to SCDT in patients with acute PE.INSPLAY registration number: INPLASY202240082.
CLINICAL IMPACT
This study compared SCDT and USAT in patients with acute pulmonary embolism. We found no additional benefit in PA pressure change, thrombus reduction, hospital stay, mortality and major bleeding rate. Additional study using consistent treatment protocol is necessary for further investigation.

Current Vascular Pharmacology 2023A list of drugs that can induce takotsubo cardiomyopathy (TCM) was published in 2011 and 2016. The aim of the present review was to update this list.
BACKGROUND
A list of drugs that can induce takotsubo cardiomyopathy (TCM) was published in 2011 and 2016. The aim of the present review was to update this list.
METHODS
Similar to the 2011 and 2016 reviews, from April 2015 to May 2022 case reports of druginduced TCM were identified by a comprehensive search in Medline/PubMed database. The search terms were: takotsubo cardiomyopathy, tako-tsubo cardiomyopathy, stress cardiomyopathy, transientleft- ventricular ballooning syndrome, apical ballooning syndrome, ampulla cardiomyopathy OR broken heart syndrome; together with "iatrogenic", "induced by" OR "drug-induced". Registers published in English or Spanish, in humans, and with full texts were retrieved. Articles that recognized any drug associated with the development of TCM were selected.
RESULTS
Overall, 184 manuscripts were identified by the search. A total of 39 articles were included after an exhaustive revision. Eighteen drugs as possible triggers of TCM were identified in the current update. Of them, 3 (16.7%) have been previously identified, and 15 (83.3%) are different from the previous reports. Thus, the list of drugs as possible triggers of TCM updated in 2022 includes 72 drugs.
CONCLUSION
There are new case reports that link drugs with the development of TCM. The current list is principally made up of drugs that generate sympathetic overstimulation. However, some of the listed drugs do not have a clear link with sympathetic activation.

Meta-Analysis Review
BACKGROUND
Intravenous magnesium (IV Mg), a commonly utilized therapeutic agent in the management of atrial fibrillation (AF) with rapid ventricular response, is thought to exert its influence via its effect on cellular automaticity and prolongation of atrial and atrioventricular nodal refractoriness thus reducing ventricular rate. We sought to undertake a systematic review and meta-analysis of the effectiveness of IV Mg versus placebo in addition to standard pharmacotherapy in the rate and rhythm control of AF in the nonpostoperative patient cohort given that randomized control trials (RCTs) have shown conflicting results.
METHODS
Randomized controlled trials comparing IV Mg versus placebo in addition to standard of care were identified via electronic database searches. Nine RCTs were returned with a total of 1048 patients. Primary efficacy endpoints were study-defined rate control and rhythm control/reversion to sinus rhythm. The secondary endpoint was patient experienced side effects.
RESULTS
Our analysis found IV Mg in addition to standard care was successful in achieving rate control (odd ratio [OR] 1.87, 95% confidence interval [CI] 1.13-3.11, p = .02) and rhythm control (OR 1.45, 95% CI 1.04-2.03, p = .03). Although not well reported among studies, there was no significant difference between groups regarding the likelihood of experiencing side effects.
CONCLUSIONS
IV Mg, in addition to standard-of-care pharmacotherapy, increases the rates of successful rate and rhythm control in nonpostoperative patients with AF with rapid ventricular response and is well tolerated.

BACKGROUND
Isolated coronary artery fistula (CAF) is a rare entity in which evidence for both prognosis and need for perinatal treatment is lacking. We aim to evaluate the characteristics, evolution and perinatal outcomes of reported cases, including one from our center.
MATERIAL AND METHODS
We performed a systematic review in Medline, Pubmed, and Embase databases for cohort studies or case series related to prenatally diagnosed isolated congenital CAF according to PRISMA guidelines. The search was restricted to articles published until January 2022, including a case report from our center. A descriptive analysis was performed, and perinatal characteristics were dichotomized by outcome (development of symptoms, as well as the need for surgery during the neonatal period). Strength of association between prenatal variables and outcome was evaluated through Odds Ratio.
RESULTS
Only 27 cases of prenatal diagnosis of isolated CAF have been published, including our patient. Most had their origin in the right coronary artery (63%) and drained in the right ventricle (55.6%). Most cases (72%) developed progressive intrauterine dilation of the fistulous tract, which was usually associated with symptoms of cardiac overload, such as cardiomegaly (57.7%). Up to two-thirds of prenatally diagnosed patients developed heart failure symptoms in the neonatal period, and 84% required postnatal intervention. Prenatal diagnosis of both cardiomegaly and diastolic steal is associated with an OR of 52 and 41 of developing postnatal symptoms.
CONCLUSION
Prenatal diagnosis of isolated CAF can be achieved with adequate tools and trained sonographers. The development of cardiomegaly and diastolic steal significantly increases the risk of developing postnatal symptoms.

Review
The aim of this review is to identify possible structural abnormalities of BrS and their potential association with symptoms, risk stratification, and prognosis. (1) Background: BrS has always been considered a purely electrical disease and imaging techniques do not currently play a specific role in the diagnosis of this arrhythmic syndrome. Some authors have recently hypothesized the presence of structural and functional abnormalities. Therefore, several studies investigated the presence of pathological features in echocardiography and cardiac magnetic resonance imaging (MRI) in patients with BrS, but results were controversial. (2) Methods: We performed a systematic review of the literature on the spectrum of features detected by echocardiography and cardiac MRI. Articles were searched in Pubmed, Cochrane Library, and Biomed Central. Only papers published in English and in peer-reviewed journals up to November 2021 were selected. After an initial evaluation, 596 records were screened; the literature search identified 19 relevant articles. (3) Results: The imaging findings associated with BrS were as follows: right ventricular dilation, right ventricular wall motion abnormalities, delayed right ventricular contraction, speckle and feature tracking abnormalities, late gadolinium enhancement, and fat infiltration in the right ventricle. Furthermore, these features emerged more frequently in patients carrying the genetic mutation on the sodium voltage-gated channel α-subunit 5 (SCN5A) gene. (4) Conclusions: Specific imaging features detected by echocardiography and cardiac magnetic resonance are associated with BrS. However, this population appears to be heterogeneous and imaging anomalies emerged to be more frequent in patients carrying genetic mutations of SCN5A. Future studies with an evaluation of BrS patients are needed to identify the specific association linking the Brugada pattern, imaging abnormalities and their possible correlation with prognosis.
