RESUMO
Representation of women in interventional vascular fields (interventional cardiology, interventional radiology, and vascular surgery) lags behind that in other specialties. With women representing half of all medical school graduates, encouraging parity of women in these fields needs to start in medical school. Barriers to pursuing careers in vascular intervention include insufficient exposure during core clerkships, early mentorship, visibility of women in the field, length of training, lifestyle considerations, work culture and environment, and concerns about radiation exposure. This scientific statement highlights potential solutions for both the real and perceived barriers that women may face in pursuing careers in vascular intervention, including streamlining of training (as both interventional radiology and vascular surgery have done with a resultant increase in percentage of women trainees), standardization of institutional promotion of women in leadership, and professional and industry partnerships for the retention and advancement of women.

BACKGROUND: Most patients undergoing the mitral transcatheter edge-to-edge repair (TEER) technique are elderly comorbid patients. Low body mass index (BMI) < 23 kg/m2 has been identified in other elderly populations as a risk factor, but has not been studied sufficiently in mitral TEER. AIMS: We aimed to study the impact of low BMI (23 kg/m2) on the outcome after mitral TEER. METHODS: Patients undergoing first-time TEER for mitral regurgitation at a single tertiary center were included, with the exclusion of patients with preprocedural hemodynamic instability or missing BMI. The primary endpoint was all-cause mortality. Secondary endpoints were long-term major bleeding or admission with heart failure. RESULTS: A total of 120 patients (mean age 76 ± 10 years, 76% men) were included in the study. Thirty-nine (31%) had low BMI. Patients with low BMI had a similar symptomatic benefit as patients with BMI ≥ 23 kg/m2 at 1 year regarding decrease in diuretics dose and decrease in New York Heart Association (NYHA) class (p > 0.05). In a multivariable Cox regression analysis, BMI as a continuous variable (hazard ratio [HR]: 0.93 [95% confidence interval, CI: 0.87-0.99], p = 0.03) and low BMI (HR: 1.99 [95% CI: 1.12-3.52], p = 0.02) were associated with the primary outcome. Low BMI was not significantly associated with major bleeding (subdistribution hazard ratio [SHR]: 2.39 [95% CI: 0.96-5.97], p = 0.06) or admission with heart failure (SHR: 1.06 [95% CI: 0.61-1.88], p = 0.83) during follow-up with univariable competing risk regression analysis. CONCLUSION: Low BMI is a risk factor for mortality after mitral valve TEER, confirming the presence of an "obesity paradox" in this population and should receive attention in patient selection.

This study aimed to evaluate the current state of congenital interventional cardiology training worldwide, with a focus on case volumes, competency assessment, and the need for ongoing mentorship during early career stages. A survey was conducted among program directors (PDs) of congenital interventional training programs across the globe. The survey gathered data on training pathways, case volumes, types of procedures performed, trainee competency assessment, and the role of ongoing mentorship. Of the 79 PDs who completed the survey, it was observed that training pathways and case volumes varied significantly, particularly between the United States and other countries. Most PDs reported an annual laboratory case volume of >500 congenital cardiac cases, with most cases being interventional. While trainees demonstrated competency in simple procedures (diagnostic cases, simple ASD closure), complex interventions (such as patent ductus arteriosus closure in premature infants) require ongoing mentorship for graduates. PDs recommended a minimum case volume of 400 total cases for trainees, including 250 interventional cases. In addition to case volumes, assessing trainee competency was deemed important, with clinical reasoning, judgment, skillset, teamwork, and complication management being key areas of evaluation. The study highlights the variability in congenital interventional cardiology training and the need for ongoing mentorship during the early career years. External mentorship programs, facilitated by national and international societies, are proposed to provide critical support for early career interventionalists thus enhancing patient care for congenital heart disease. Ultimately, the findings of this survey may serve as a framework for future training standards and guidelines in this specialized field.
RESUMO
Despite the increasing proportion of female medical and nursing students, there is still a significant under-representation of women working as healthcare providers in interventional cardiology, with very few of them reaching senior leadership, academic positions, or acting principal investigators, as well as actively involved in company advisory boards. In this position paper, we will describe the current status of women working in interventional cardiology across Europe. We will also provide an overview of the most relevant determinants of the under-representation of women at each stage of the interventional cardiology career path and offer practical suggestions for overcoming these challenges.

We present the benefits of advanced multimodality imaging and virtual reality modelling in the diagnosis and treatment planning of a child with aneurysms after numerous interventions for treatment of a hypoplastic aortic arch and coarctation.
RESUMO
In the dynamic field of interventional cardiology, significant strides have been made in reducing periprocedural complications. Echocardiography, particularly transesophageal echocardiography, plays a key role in ensuring the safety and success of structural heart interventions. Its real-time imaging capabilities allow for precise monitoring of device positioning, deployment, and procedural outcomes. By adhering to established imaging protocols and acquiring standard imaging planes, periprocedural echocardiography has become an essential tool for the successful performance of many structural heart interventions. In this manuscript, we present a series of unusual yet significant complications that we encountered during structural interventional procedures in our catheter laboratory. These complications, detected through echocardiography, underscore the critical role of imaging guidance in recognizing, and addressing unforeseen challenges, such as device malposition, thrombus formation in cardiac chambers during structural heart interventions, and cardiac tamponade during transcatheter mitral valve procedures. Through these cases, we highlight the effectiveness of transesophageal echocardiography in promptly identifying complications, allowing for timely intervention and resolution.
RESUMO
Background.Anecdotal reports are appearing in the scientific literature about cases of brain tumors in interventional physicians who are exposed to ionizing radiation. In response to this alarm, several designs of leaded caps have been made commercially available. However, the results reported on their efficacy are discordant.Objective.To synthesize, by means of a systematic review of the literature, the capacity of decreasing radiation levels conferred by radiation attenuating devices (RADs) at the cerebral level of interventional physicians.Methodology.A systematic review was performed including the following databases: MEDLINE, SCOPUS, EBSCO, Science Direct, Cochrane Controlled Trials Register (CENTRAL), WOS, WHO International Clinical Trials Register, Scielo and Google Scholar, considering original studies that evaluated the efficacy of RAD in experimental or clinical contexts from January 1990 to May 2023. Data selection and extraction were performed in triplicate, with a fourth author resolving discrepancies.Results.Twenty articles were included in the review from a total of 373 studies initially selected from the databases. From these, twelve studies were performed under clinical conditions encompassing 3801 fluoroscopically guided procedures, ten studies were performed under experimental conditions with phantoms, with a total of 88 procedures, four studies were performed using numerical calculations with a total of 63 procedures. The attenuation and effectiveness of provided by the caps analyzed in the present review varying from 12.3% to 99.9%, and 4.9% to 91% respectively.Conclusion.RAD were found to potentially provide radiation protection, but a high heterogeneity in the shielding afforded was found. This indicates the need for local assessment of cap efficiency according to the practice.

In response to the International Commission on Radiological Protection (ICRP), which lowered the lens equivalent dose limit, Japan lowered the lens dose limit from 150 mSv/year to 100 mSv/5 years and 50 mSv/year, with this new rule taking effect on April 1, 2021. DOSIRIS® is a dosimeter that can accurately measure lens dose. Herein, we investigated lens dose in interventional cardiology physicians one year before and after the reduction of the lens dose limit using a neck dosimeter and lens dosimeter measurements. With an increase in the number of cases, both personal dose equivalent at 0.07 mm [Hp(0.07), neck dosimeter] and personal dose equivalent at 3 mm depth [Hp(3), lens dosimeter] increased for most of the physicians. The Hp(3) of the lens considering the shielding effect of the Pb glasses using lens dosimeter exceeded 20 mSv/year for two of the 14 physicians. Protection from radiation dose will become even more important in the future, as these two physicians may experience radiation dose exceeding 100 mSv/5 years. The average dose per procedure increased, but not significantly. There was a strong correlation between the neck dosimeter and lens dosimeter scores, although there was no significant change before and after the lens dose limit was lowered. This correlation was particularly strong for physicians who primarily treated patients. As such, it is possible to infer accurate lens doses from neck doses in physicians who primarily perform diagnostics. However, it is desirable to use a dosimeter that can directly measure Hp(3) because of the high lens dose.
RESUMO
Background: Transfemoral transcatheter aortic valve implantation (TAVI) has proven non-inferior or superior against surgical aortic valve replacement (SAVR) for patients at high, intermediate or low surgical risk. However, transfemoral access is not always feasible in patients with severely atherosclerotic or tortuous iliofemoral arteries. For these cases, alternative access techniques have been developed, such as transcarotid, transcaval, direct aortic or transaxillary access. In recent years, growing preference towards the transaxillary access has emerged. To provide a summary of data available on transaxillary TAVI and compare this approach to other alternative access techniques. Methods: A literature search was performed in PubMed by two independent reviewers. Studies reporting the outcome of at least 10 patients who underwent transaxillary TAVI, either in case series or in comparative studies, were included in this review. Articles not reporting outcomes according to the Valve Academic Research Consortium (VARC) 1-3 definitions were excluded. Results: In total 193 records were found of which 18 were withheld for inclusion in this review. This review reports on the combined data of the 1519 patients who underwent transaxillary TAVI. Procedural success was achieved in 1203 (92.2%) of 1305 cases. Life-threatening, major, and minor bleeding occurred respectively in 4.5% (n = 50 in 1112 cases), 12.9% (n = 143 in 1112 cases) and 8.8% (n = 86 in 978 cases). Major and minor vascular complications were reported in respectively 6.6% (n = 83 in 1256 cases) and 10.0% (n = 105 in 1048 cases) of patients. 30-day mortality was 5.2% (n = 76 out of 1457 cases). At one year follow-up, the mortality rate was 1% (n = 184 out of 1082 cases). Similar 30-day and 1-year mortality is observed in studies that compare with transaxillary, transfemoral or other alternative access techniques (p > 0.05). Conclusions: A wide application of transaxillary access as an alternative approach for TAVI has emerged. This technique has an excellent procedural success rate up to 92.0%, with low procedural complication rates. Clinical outcome of transaxillary TAVI is comparable to the other alternative TAVI approaches. However, these conclusions are solely based on observational data.
RESUMO
The Coronary Sinus Reducer® (CSR) is an emerging therapy for refractory angina recommended once no further pharmacologic or coronary revascularization options are available. We present the case of a 72-year-old man who underwent CSR implantation. Complex coronary sinus anatomy necessitated an innovative "grandmother, mother, and child" catheter approach.

Over the latest years, the use of distal radial access (dTRA), also called "snuffbox," has become more and more popular for cardiac catheterization. Indeed, dTRA has several advantages compared to the traditional proximal radial approach, such as a lower risk of hand ischemia, radial artery occlusion (RAO) and faster post-procedural hemostasis. However, due to the presence of different muscular-skeletal structures, as well as to the small diameter of the distal radial artery (dRA), an ultrasound-guided cannulation would be preferred since a blind puncture increases the risk of tendon damage and/or the irritation of the underlying periosteum. The present article is aimed to provide the key tips for performing US-guided access using the dRA in patients undergoing percutaneous cardiac procedures.
RESUMO
INTRODUCTION: In the United States, there is an anticipated critical shortage of vascular surgeons in the coming decades. The shortage is expected to be particularly pronounced in rural areas. Our institution serves a rural and underserved population in which the incidence and prevalence of cardiovascular disease continues to rise. Our institution maintains a general surgery residency and has all the required Accreditation Council for Graduate Medical Education (ACGME) rotations and educational infrastructure to support a vascular surgery fellowship. This study aims to analyze the vascular caseload at our institution to determine if we and other institutions with similar surgical volumes can support the creation of a 2-year vascular fellowship. METHODS: A single-site retrospective review of the number and type of vascular cases conducted at our institution between July 2016 and June 2021 was performed. The procedures were grouped into the following ACGME-defined categories: abdominal, cerebrovascular, complex, endovascular aneurysm repair, endovascular diagnostic or therapeutic, and peripheral. The total number and annual average for each category was obtained. Using the annual average, a 2-year estimate was calculated and compared to the ACGME minimum for each category. Our 2-year estimate was then compared to the national average for graduating vascular surgery fellows in order to generate a z-score for each category. RESULTS: In the specified period, 6100 total surgical procedures were performed by three vascular surgeons at our institution. Two thousand five hundred and seventy-eight of the 6100 procedures met at least one of the ACGME-defined category requirements. Our center greatly exceeded the requirements for each category except for abdominal. This is consistent with trends observed in most centers across the nation, which are seeing a decline in open repairs across all categories, especially in open abdominal repairs. Our center's vascular case volume shows no significant difference the national average in each ACGME category (P ≥ 0.05 for all). CONCLUSIONS: Despite our center's large vascular caseload and need for more vascular providers, there were not enough open abdominal cases performed to support the training of a vascular fellow. Given the continued decline in open aortic volume across the country, we anticipate that rural centers similar to our own will have difficulty establishing programs to train and recruit vascular surgeons. Flexibility in the abdominal category requirement or creation of open aortic fellowships may be necessary for smaller rural centers to train vascular surgeons and meet the future needs of the specialty.

INTRODUCTION: Percutaneous left atrial appendage closure (LAAC) has shown non-inferiority compared to oral anticoagulation (OAC) in preventing atrial fibrillation (AF)-related stroke. The objective of this study was to assess whether LAAC reduces the incidence of gastrointestinal bleeding (GIB) and/or chronic anaemia associated with OAC, as well as the consumption of healthcare resources. MATERIALS AND METHODS: Prospective, single-center study from 2016 to 2022, LAAC was performed. Clinical, analytical and healthcare resource consumption data were collected (endoscopies, blood transfusions, hospital admissions) prior and 6 months after LAAC. RESULTS: 43 patients were included, with an average age of 77.6 years. LAAC indication was upper, low and obscure GIB in 7 (16%), 8 (19%) and 28 patients (65%) respectively. GIB source was intestinal angiodysplasias in 27 patients (63%), occult origin in 12 (28%), and others (antral vascular ectasia, portal hypertension gastropathy, etc.) in 4 patients (9%). The mean number of packed red blood cells per patient before LAAC was (mean ± SD) 7.29 ± 5 vs 0.42 ± 1.3 (p < 0.001); endoscopic procedures were 4.34 ± 2.85 vs 0.27 ± 0.76 (p < 0.001); and hospitalizations 2.67 ± 2.14 vs 0.03 ± 0.17 (p < 0.001), with a hospital stay of 21.5 ± 17.3 vs 0.09 ± 0.5 days (p < 0.001) at 6 months post-intervention. Haemoglobin value increased from 8.1 ± 1.2g/dl to 12.4 ± 2.2g/dl (p < 0.001) at 6 months. No thromboembolic events were registered during a median follow-up of 16.6 months (range 6-65). CONCLUSIONS: LAAC could be a safe and effective alternative to OAC in patients with non-valvular AF presenting significant, recurrent or potentially unresolvable GIB. This intervention also leads to important savings in the consumption of healthcare resources.

BACKGROUND: Optimizing patient exposure in interventional cardiology is key to avoid skin injuries. PURPOSE: To establish predictive models of peak skin dose (PSD) during percutaneous coronary intervention (PCI), chronic total occlusion percutaneous coronary intervention (CTO), and transcatheter aortic valve implantation (TAVI) procedures. MATERIAL AND METHODS: A total of 534 PCI, 219 CTO, and 209 TAVI were collected from 12 hospitals in eight European countries. Independent associations between PSD and clinical and technical dose determinants were examined for those procedures using multivariate statistical analysis. A priori and a posteriori predictive models were built using stepwise multiple linear regressions. A fourfold cross-validation was performed, and models' performance was evaluated using the root mean square error (RMSE), mean absolute percentage error (MAPE), coefficient of determination (R²), and linear correlation coefficient (r). RESULTS: Multivariate analysis proved technical parameters to overweight clinical complexity indices with PSD mainly affected by fluoroscopy time, tube voltage, tube current, distance to detector, and tube angulation for PCI. For CTO, these were body mass index, tube voltage, and fluoroscopy contribution. For TAVI, these parameters were sex, fluoroscopy time, tube voltage, and cine acquisitions. When benchmarking the predictive models, the correlation coefficients were r = 0.45 for the a priori model and r = 0.89 for the a posteriori model for PCI. These were 0.44 and 0.67, respectively, for the CTO a priori and a posteriori models, and 0.58 and 0.74, respectively, for the TAVI a priori and a posteriori models. CONCLUSION: A priori predictive models can help operators estimate the PSD before performing the intervention while a posteriori models are more accurate estimates and can be useful in the absence of skin dose mapping solutions.

BACKGROUND: Patients can be exposed to high skin doses during complex interventional cardiology (IC) procedures. PURPOSE: To identify which clinical and technical parameters affect patient exposure and peak skin dose (PSD) and to establish dose reference levels (DRL) per clinical complexity level in IC procedures. MATERIAL AND METHODS: Validation and Estimation of Radiation skin Dose in Interventional Cardiology (VERIDIC) project analyzed prospectively collected patient data from eight European countries and 12 hospitals where percutaneous coronary intervention (PCI), chronic total occlusion PCI (CTO), and transcatheter aortic valve implantation (TAVI) procedures were performed. A total of 62 clinical complexity parameters and 31 technical parameters were collected, univariate regressions were performed to identify those parameters affecting patient exposure and define DRL accordingly. RESULTS: Patient exposure as well as clinical and technical parameters were collected for a total of 534 PCI, 219 CTO, and 209 TAVI. For PCI procedures, body mass index (BMI), number of stents ≥2, and total stent length >28â mm were the most prominent clinical parameters, which increased the PSD value. For CTO, these were total stent length >57â mm, BMI, and previous anterograde or retrograde technique that failed in the same session. For TAVI, these were male sex, BMI, and number of diseased vessels. DRL values for Kerma-area product (PKA), air kerma at patient entrance reference point (Ka,r), fluoroscopy time (FT), and PSD were stratified, respectively, for 14 clinical parameters in PCI, 10 in CTO, and four in TAVI. CONCLUSION: Prior knowledge of the key factors influencing the PSD will help optimize patient radiation protection in IC.

Augmented reality (AR) visualization of 3D rotational angiography (3DRA) provides 3D representations of cardiac structures with full visualization of the procedural environment. The purpose of this study was to evaluate the feasibility of converting 3DRAs of congenital heart disease patients to AR models, highlight the workflow for 3DRA optimization for AR visualization, and assess physicians' perceptions of their use. This single-center study prospectively evaluated 30 retrospectively-acquired 3DRAs that were converted to AR, compared to Computer Models (CM). Median patient age 6.5 years (0.24-38.8) and weight 20.6 kg (3.4-107.0). AR and CM quality were graded highly. RV pacing was associated with higher quality of both model types (p = 0.02). Visualization and identification of structures were graded as "very easy" in 81.1% (n = 73) and 67.8% (n = 61) of AR and CM, respectively. Fifty-nine (66%) grades 'Agreed' or 'Strongly Agreed' that AR models provided superior appreciation of 3D relationships; AR was found to be least beneficial in visualization of aortic arch obstruction. AR models were thought to be helpful in identifying pathology and assisting in interventional planning in 85 assessments (94.4%). There was significant potential seen in the opportunity for patient/family counseling and trainee/staff education with AR models. It is feasible to convert 3D models of 3DRAs into AR models, which are of similar image quality as compared to CM. AR models provided additional benefits to visualization of 3D relationships in most anatomies. Future directions include integration of interventional simulation, peri-procedural counseling of patients and families, and education of trainees and staff with AR models.
RESUMO
Since last year's report in the European Heart Journal, we have witnessed substantial progress in all aspects of interventional cardiology. Of note, the practice of interventional cardiology took place amidst successive waves of the COVID-19 pandemic, which continues to be a major burden for all healthcare professionals around the globe. In our yearly review, we shall revisit the developments in percutaneous coronary intervention (PCI), structural heart interventions, and adjunctive pharmacotherapy.

The European Congenital Heart Surgeons Association (ECHSA) Congenital Database (CD) is the second largest clinical pediatric and congenital cardiac surgical database in the world and the largest in Europe, where various smaller national or regional databases exist. Despite the dramatic increase in interventional cardiology procedures over recent years, only scattered national or regional databases of such procedures exist in Europe. Most importantly, no congenital cardiac database exists in the world that seamlessly combines both surgical and interventional cardiology data on an international level; therefore, the outcomes of surgical and interventional procedures performed on the same or similar patients cannot easily be tracked, assessed, and analyzed. In order to fill this important gap in our capability to gather and analyze information on our common patients, ECHSA and The Association for European Paediatric and Congenital Cardiology (AEPC) have embarked on a collaborative effort to expand the ECHSA-CD with a new module designed to capture data about interventional cardiology procedures. The purpose of this manuscript is to describe the concept, the structure, and the function of the new AEPC Interventional Cardiology Part of the ECHSA-CD, as well as the potentially valuable synergies provided by the shared interventional and surgical analyses of outcomes of patients. The new AEPC Interventional Cardiology Part of the ECHSA-CD will allow centers to have access to robust surgical and transcatheter outcome data from their own center, as well as robust national and international aggregate outcome data for benchmarking. Each contributing center or department will have access to their own data, as well as aggregate data from the AEPC Interventional Cardiology Part of the ECHSA-CD. The new AEPC Interventional Cardiology Part of the ECHSA-CD will allow cardiology centers to have access to aggregate cardiology data, just as surgical centers already have access to aggregate surgical data. Comparison of surgical and catheter interventional outcomes could potentially strengthen decision processes. A study of the wealth of information collected in the database could potentially also contribute toward improved early and late survival, as well as enhanced quality of life of patients with pediatric and/or congenital heart disease treated with surgery and interventional cardiac catheterization across Europe and the world.

Objective. To evaluate the value of individualized planning of left atrial appendage occlusion (LAAO) using cardiac computed tomography angiography (CCTA) reconstruction techniques. Methods. A total of 96 patients treated for LAAO with the Watchman occluder were included in this study. All patients were randomized by random number table in a 2:1 ratio into the CCTA (+) and CCTA (-) groups according to whether CCTA was performed preoperatively. 3D cardiac reconstruction was performed preoperatively in the CCTA (+) group to plan the location of the atrial septal puncture site, left atrial appendage(LAA) landing zone, predict the size of the occluder and simulate occluder release. In the CCTA(-) group, only transesophageal echocardiography (TEE) and fluoroscopy were used to guide LAAO. Results. The number of occluders used in a single procedure (1.06 ± .24 vs 1.22 ± .42), the number of intraoperative angiography positions (1.23 ± .58 vs 2.28 ± .85) and the procedure time (45.88 ± 5.08 vs 62.44 ± 5.60) in the CCTA(+) group were lower than in the CCTA(-) group (P < .05), and the first-attempt blocking success rate was higher than that of the CCTA(-) group (85.9% vs 65.6%, P = .021). Furthermore, the Bland-Altman plots showed good agreement between the longest diameter of the CCTA-predicted landing zone and the longest diameter of the actual landing zone (95% LoA -7.49, 10.24). A strong positive correlation was observed between the predicted compression ratio and the actual compression ratio (r = .890, P < .001). In addition, a strong positive correlation was found between the CCTA-predicted longest diameter of the landing zone and the actual occluder size (r = .863, P < .001). Conclusion. Accurate planning for LAAO using preoperative CCTA can reduce intraoperative angiography positions and occluder changes, shorten the procedure time, increase the success rate of first-attempt blocking and reduce the difficulty of the procedure.

INTRODUCTION: complex fluoroscopy-guided interventional procedures in cardiology are known to result in higher radiation doses for patients and staff. PURPOSE: to estimate the equivalent dose received in different regions of the cardiologist's body in catheterism (CATH) and percutaneous coronary intervention (PCI) procedures, as well as to evaluate the effectiveness of monitoring the doses in the catheritization laboratory (cath lab) using a direct ion storage dosimeter. MATERIALS AND METHODS: the InstadoseTMand the thermoluminescent dosimeters (TLD-100) were fixed simultaneously in the following regions of the cardiologist's body: near the eyes (left and right), the trunk region (over the lead apron) and the left ankle. Occupational doses were recorded during 86 procedures (60% CATH). RESULTS: catheterization procedures showed third quartile dose values near to the left eye region equal to 0.10 mSv (TLD-100) and 0.12 (InstadoseTM) and for intervention 0.15 mSv (TLD-100 and InstadoseTM). The doses measured in the trunk region, over the lead apron, were about 13% higher for catheterization procedures and 20% higher for intervention procedures compared to left eye region measurements. The Wilcoxon-Mann-Whitney test was applied for unpaired data for all body regions, comparing the data obtained between the TLD-100 and InstadoseTMdosimeters. For CATH and PCI, the responses of the TLD-100 and InstadoseTMdosimeters are considered equal for all analysed regions (p> 0.05) with the exception of the right eye region. CONCLUSION: the InstadoseTMpassive dosimeter can be useful as a complementary assessment in the monitoring of a cardiologist's personal occupational doses in the cath lab.
