ABSTRACT
PURPOSE: The aim of this study is to describe our initial experience using magnetic seeds (Magseed®) to guide breast-conserving surgery in non-palpable breast lesions and compare the use of magnetic seed with wires to guide breast-conserving surgery in terms of clinical and pathological characteristics. METHODS: We performed a retrospective study including all breast-conserving surgeries for non-palpable breast lesions under 16 mm from June 2018 to May 2021. We compared breast-conserving surgeries guided with magnetic seeds (Magseed®) to those guided with wires, analyzing tumor and patient characteristics, surgical time, and pathological results of the surgical specimens. RESULTS: Data from 225 cases were collected, including 149 cases guided by magnetic seeds and 76 cases guided by wires. The breast lesion was localized in every case. Both cohorts were similar regarding clinical and pathological characteristics. We found significant statistical differences (p < 0.02) in terms of the median volume (cm3) of the excised specimen, which was lower (29.3%) in the magnetic seed group compared with the wire group (32.5 [20.5-60.0]/46.0 [20.3-118.7]). We did not find significant differences regarding surgical time (min) or the affected or close margins. CONCLUSION: In our experience, the use of magnetic seed (Magseed®) is a feasible option to guide breast-conserving surgery of non-palpable lesions and enabled us to resect less breast tissue.
ABSTRACT
Purpose: Neoadjuvant endocrine treatment (NET) has become a useful tool for the downstaging of luminal-like breast cancers in postmenopausal patients. It enables us to increase breast- conserving surgery (BCS) rates, provides an opportunity for us to assess in vivo NET effectiveness, and allows us to study any biological changes that may act as valid biomarkers. The purpose of this study was to evaluate the safety and effectiveness of NET, and to assess the role of Ki67 proliferation rate changes as an indicator of endocrine responsiveness. Methods: From 2016 to 2020, a single-institution cohort of patients, treated with NET and further surgery, was evaluated. In patients with Ki67 ≥ 10%, a second core biopsy was performed after four weeks. Information regarding histopathological and clinical changes was gathered. Results: A total of 115 estrogen receptor-positive (ER+)/HER2-negative patients were included. The median treatment duration was 5.0 months (IQR: 2.0−6.0). The median maximum size in the surgical sample was 40% smaller than the pretreatment size measured by ultrasound (p < 0.0001). The median pretreatment Ki67 expression was 20.0% (IQR: 12.0−30.0), and was reduced to 5.0% (IQR: 1.8−10.0) after four weeks, and to 2.0% (IQR: 1.0−8.0) in the surgical sample (p < 0.0001). BCS was performed on 98 patients (85.2%). No pathological complete responses were recorded. A larger Ki67 fold change after four weeks was significantly related to a PEPI score of zero (p < 0.002). No differences were observed between luminal A- and B-like tumors, with regard to fold change and PEPI score. Conclusions: In our cohort, NET was proven to be effective for tumor size and Ki67 downstaging. This resulted in a higher rate of conservative surgery, aided in therapeutic decision making, provided prognostic information, and constituted a safe and well-tolerated approach.

BACKGROUND: Atrial tachycardias (ATs) are a significant source of morbidity in adults with congenital heart disease (CHD). This study evaluates the incidence and clinical predictors of AT in a cohort of patients with CHD. METHODS AND RESULTS: We included 3311 adults (median age at entry 22.6 years, 50.6% males) with CHD (49% simple, 39% moderate, and 12% complex) prospectively followed up in a tertiary center for 37 607 person-years. Predictors of AT were identified by multivariable Cox regression analysis accounting for left truncation. An external validation was performed in a contemporary cohort of 1432 patients. Overall, 153 (4.6%) patients presented AT. AT burden was highest in complex CHD, such as single ventricle (22.8%) and d-transposition of the great arteries (22.1%). Hazard rates of AT across lifetime, age at presentation, and the time lapse between surgery and the first AT episode varied among the most common CHD. Independent risk factors for developing AT were univentricular physiology, previous intracardiac repair, systemic right ventricle, pulmonary hypertension, pulmonary regurgitation, pulmonary atrioventricular valve regurgitation, pulmonary and systemic ventricular dysfunction. At the age of 40 years, AT-free survival in patients with 0, 1, 2, and ≥3 risk factors was 100%, 94%, 76%, and 50%, respectively. These findings were confirmed in the validation cohort. CONCLUSIONS: Natural history of AT differed among the most common forms of CHD. Simple clinical parameters, easily obtained by noninvasive means, were independent predictors of AT in adults with CHD. Although risk was negligible in patients without any of these factors, their addition progressively increased AT burden.

BACKGROUND: The impact of gender and aging on relative survival and causes of death in adults with congenital heart disease (ACHD) are not well known. METHODS: Single center observational longitudinal study of 3311 consecutive ACHD (50.5% males) followed up to 25years. Patients were divided by the age at last follow-up into three groups: <40, 40-65 and >65years old. Their vital status was verified by crosschecking the Spanish National Death Index. Regression model for relative survival from reference population was performed. Cause of death was classified according to the International Classification of Diseases (ICD-10). Patients who died from cardiovascular (CV) causes were further investigated on a case-by-case basis. RESULTS: During a cumulative follow-up time of 37,608 person-years 336 patients died (10%). Age-adjusted relative survival in females was significantly worse than in males (hazard ratio [HR] 1.25; 95% confidence interval [CI] 1.0-1.6; p=0.046), and sex-adjusted relative survival improved across the three group of ages (HR 0.98; 95% CI 0.97-0.99; p<0.001). There was a temporal decline of CV deaths with aging in both genders (p<0.001). The leading cause of CV death was heart failure but sudden death prevailed in subjects <40years (p=0.004). While sudden death progressively declined with aging heart failure significantly increased (p<0.001). CONCLUSIONS: Women with CHD fare worse than men. There are a decline in CV deaths and a major temporal shift in the causes of CV deaths with aging. Heart failure surpasses sudden death as the primary cause of death in survivors over 40years.

AIMS: To examine factors related to excess mortality in a cohort of adults with congenital heart disease (CHD). METHODS AND RESULTS: We conducted a survival analysis using prospective data of 3311 adults with CHD [50.5% males, median age at entry 22.5 years (IQR 18-39), median follow-up time 10.5 years (IQR: 4.4-18)]. Survival status of each patient was further verified by cross checking with the Spanish National Death Index. During a total follow-up of 37608 person-years, 336 (10%) patients died. Annual death rate was 0.89% and standardized mortality ratio (SMR) 2.64 [95% confidence interval (CI) 2.3-3.0; P < 0.001]. Median age at death estimated by left-truncated Kaplan-Meier method was 75.1 years (95% CI 73-77). Survival was reduced compared with the general population whatever their level of complexity, repair status, or underlying CHD. Independent risk factors for excess mortality, including cyanosis, univentricular physiology, genetic disorders, ventricular dysfunction, residual haemodynamic lesions and acquired late complications, among others, were identified by left-truncated Cox regression model. SMR was 5.22 (95% CI 4.5-6.0; P < 0.001) and median age at death 55.6 years (95% CI 50-61) for 996 patients (30%) with at least one risk factor. In contrast, SMR was 1.14 (95% CI 0.9-1.5; P = 0.19) and median age at death 83.7 years (95% CI 82-87) in 2315 patients (70%) with no risk factors. CONCLUSIONS: Clinical parameters, such as anatomical features, haemodynamic sequelae, or acquired complications, were independent predictors of excess mortality in adults with CHD. Survival of individuals with no risk factors did not differ from the reference population.

The incidence and risk factors for prosthetic pulmonary valve failure (PPVF) should be considered when determining optimal timing for pulmonary valve replacement (PVR) in asymptomatic patients with congenital heart disease (CHD). The cumulative freedom for reintervention due to PPVF after 146 PVR in 114 patients with CHD was analyzed. Six potential risk factors (underlying cardiac defect, history of palliative procedures, number of previous cardiac interventions, hemodynamic indication for PVR, type of intervention, and age at intervention) were analyzed using Cox proportional hazard modeling. Receiver operating characteristic (ROC) curves were used for discrimination. Internal validation in patients with tetralogy of Fallot was also performed. Median age at intervention was 23 years. There were 60 reinterventions due to PPVF (41%). Median event-free survival was 14 years (95% confidence interval [CI] 12 to 16 years). The only independent risk factor was the age at intervention (hazard ratio [HR] 0.93, 95% CI 0.90 to 0.97; p = 0.001; area under the ROC curve 0.95, 95% CI 0.92 to 0.98; p <0.001). The best cut-off point was 20.5 years. Freedom from reintervention for PPVF 15 years after surgery was 70% when it was performed at age >20.5 years compared with 33% when age at intervention was <20.5 years (p = 0.004). Internal validation in 102 PVR in patient cohort with tetralogy of Fallot (ROC area 0.98, 95% CI 0.96 to 1.0; p <0.001) was excellent. In conclusion, age at intervention is the main risk factor of reintervention for PPVF. The risk of reintervention is 2-fold when PVR is performed before the age of 20.5 years.

The long-term outcome of patients with congenitally corrected transposition of the great arteries is mainly determined by progressive morphologically tricuspid valve regurgitation, heart block, atrial arrhythmias, and/or systemic ventricular dysfunction. Situs abnormalities have been reported in ≤34% of cases, but whether clinical differences exist between a situs inversus and situs solitus arrangement has not yet been studied. The clinical records of 38 adults with congenitally corrected transposition of the great arteries (mean age 40 ± 15 years) followed for a mean period of 7.4 years were reviewed. Of these 38 patients, 8 presented with situs inversus and 30 with situs solitus. No significant differences were found between the 2 groups in age, gender, ventricular septal defect, pulmonary tract stenosis, previous surgical repair, or duration of follow-up. However, none of the patients with situs inversus presented with an Ebstein-like anomaly of the morphologically tricuspid valve and none developed nonoperative-related complete atrioventricular block compared to 15 (50%; p = 0.013) and 11 (42%; p = 0.032) of the patients with situs solitus, respectively. At follow-up, 2 patients with situs inversus (25%) presented with sustained atrial arrhythmia, severe tricuspid regurgitation, or severe systemic right ventricular systolic dysfunction compared to 22 (73%) of 30 those with situs solitus (p = 0.034). No patient with situs inversus presented with cardiac death or severe heart failure compared to 12 (40%) of 30 with situs solitus (p = 0.038). In conclusion, Ebstein-like anomaly or spontaneous complete atrioventricular block are rare in patients with congenitally corrected transposition of the great arteries with situs inversus, and late complications are uncommon. The long-term outcome of patients with situs inversus was significantly better than that for patients with situs solitus.

Many adult survivors of repaired congenital heart disease (CHD) are at premature risk of death. Sudden cardiac arrest (SCA) is 1 of the leading causes of death but little is known about determinants for SCA in adults with repaired lesions. We sought to determine incidence and risk factors for SCA in a study population of 936 adults with previously repaired CHD who had completed follow-up at a single tertiary center during a mean period of 9 ± 7 years. Mean age at first examination in our institution was 21 ± 7 years. Diagnostic categories included tetralogy of Fallot (216), coarctation of the aorta (157), transposition complexes (99), single ventricle (55), and other CHD (409). During a total follow-up of 8,387 person-years, 22 patients (2.6 per 1,000 person-years) presented with SCA. Incidence of SCA varied widely between specific lesions; the highest incidence was observed in transposition complexes (10 per 1,000 person-years). Independent predictors of SCA were retrospectively identified using multivariate Cox proportional hazard modeling. Age at initial examination and severely impaired subaortic ventricular systolic function were independent risk factors for SCA (severe subaortic ventricular systolic dysfunction, adjusted hazard ratio 29, 95% confidence interval 11 to 72, p <0.001). SCA occurred in 23% of patients with severe subaortic ventricular systolic dysfunction versus 0.7% of patients with nonsevere decreased subaortic ventricular function (p <0.001). In conclusion, severe subaortic ventricular systolic dysfunction is a dominant multivariate predictor of SCA in an unselected population of adult survivors after surgery for CHD. Our data support the consideration of primary prevention strategies in these patients.

The actual incidence of ascending aorta complications (AACs) in adults with bicuspid aortic valve (BAV) and the role of associated coarctation of the aorta (COA) as an independent risk factor for AACs remain unknown. From the Adult Congenital Heart Disease database at La Paz Hospital, 631 patients in whom a BAV was diagnosed by echocardiography or surgical inspection since December 1989 were identified. These patients were then further subdivided into 2 groups according to the presence of an associated COA. AACs included aortic aneurysms (ascending aorta > or =55 mm) and aortic dissection, rupture, or perforation. Patients with a BAV and COA had a greater prevalence of AACs (8.0%) than those with an isolated BAV (3.7%; p = 0.037). The coexistence of COA was the only significant predictor of AACs (odds ratio 4.7, 95% confidence interval 1.5 to 15; p = 0.01). From the total patient group with a BAV, the clinical and echocardiographic data were reviewed for 341 patients without an AAC at baseline (97 with and 244 without COA) who had undergone serial examinations >1 year apart. The median follow-up was 7 years (interquartile range 3.5 to 10.2; total 2,436 patient-years). A new AAC occurred in 13 patients (0.5/100 patient-years). The incidence of AACs was 1.3/100 patient-years in the COA group versus 0.2/100 patient-years in the non-COA group (hazard ratio 7.5, 95% confidence interval 2.0 to 28, p = 0.002). All acute aortic events (dissection or rupture) at follow-up occurred in patients with a BAV and COA. In conclusion, the long-term incidence of AACs in patients with isolated BAV is low, but patients with BAV and associated COA are at increased risk.

An increased incidence of Wolff-Parkinson-White (WPW) syndrome with tricuspid atresia has been reported. Although atrioventricular accessory pathways may develop across suture lines after the Fontan-Björk procedure, the presence of multiple acquired accessory pathways has only been described rarely. We report on a case of a female with tricuspid atresia who underwent the Fontan operation at 5 years of age. One year later, she developed a WPW pattern. Narrow complex tachycardias started at the age of 18. An electrophysiological study revealed the presence of three accessory pathway connections at the surgical anastomosis level. All of them were successfully ablated and there were no recurrences.

OBJECTIVES: We sought to determine the prevalence and predisposing condition for aortic wall complications in adults with either repaired or non-repaired coarctation of the aorta. BACKGROUND: Aortic wall complications may develop in adults with coarctation of the aorta, despite successful surgical repair in childhood. METHODS: A total of 235 adults with coarctation (mean age 27 +/- 13 years) were retrospectively reviewed. Treatment had been performed by surgery in 181 patients (group I) or by balloon angioplasty or stenting in 28 patients (group II). No previous intervention had been carried out in 26 patients with mild coarctation at diagnosis (group III). RESULTS: Forty-four aortic wall complications were found in 37 patients (16%). There were no differences among the three groups with respect to total complications (15%, 18%, and 15%, respectively), ascending aortic aneurysms (9%, 11%, and 12%), or descending aortic aneurysms (4% in all three groups). Multivariate analysis did not show a significant relationship between previous repair, type of repair, age at repair, residual Doppler pressure gradient, or systemic hypertension and the occurrence of aortic complications. Only aging (risk ratio [RR] 1.4 per decade of age, 95% confidence interval [CI] 1.1 to 1.8, p = 0.002) and bicuspid aortic valve (RR 3.2, 95% CI 1.3 to 7.5, p = 0.005) were significantly related to these complications. CONCLUSIONS: Aortic wall complications are frequent in adults with coarctation of the aorta beyond that attributable to associated hemodynamic derangement or previous repair. The only independent risk factors appear to be advanced age and bicuspid aortic valve.

OBJECTIVE: The purpose of this study was to determine the rate of progression of midventricular obstruction in adolescents and adults with double-chambered right ventricle. METHODS: Clinical and echocardiographic findings in 45 patients (mean age 26 +/- 6 years, range 15-44) diagnosed with double-chambered right ventricle were retrospectively analyzed. Twenty patients underwent surgical repair before the age of 15 years. The relationship between Doppler midventricular pressure gradient and patient age was analyzed in 25 patients without previous repair. Sequential change in midventricular obstruction was determined for patients with 2 or more Doppler echocardiographic examinations performed within at least a 2-year interval. RESULTS: Right midventricular pressure gradient in nonrepaired patients was 70 +/- 38 mm Hg (range 25-150). A significant relationship between midventricular obstruction and patient age (r = 0.64, P <.001) was found. Midventricular pressure gradient at initial evaluation was 32 +/- 27 mm Hg in 16 patients < 25 years and 73 +/- 45 mm Hg in 9 patients >/= 25 years (P <.03). After the initial study, 5 patients underwent surgical repair and 13 patients without repair were followed up for a period of 6.1 +/- 2.7 years (range 2-9), in which midventricular pressure gradient increased from 32 +/- 26 mm Hg to 67 +/- 35 mm Hg (P <.001). The slope of the change in midventricular pressure gradient was 6.2 +/- 3 mm Hg per year of follow-up. Seven more patients underwent surgical repair during follow-up due to progression of the obstruction. There was no mortality nor residual midventricular obstruction in surgically repaired patients. CONCLUSIONS: Mild right midventricular obstruction shows a fast rate of progression in adolescents and young adults. Thus, close clinical and echocardiographic follow-up is advised, and surgical repair should be considered if significant progression of obstruction is detected.

The aims of this study were to determine the prevalence and predisposing conditions for atrial fibrillation (AF) in adults with atrial septal defect (ASD) and to evaluate the influence of age at surgical repair. The study population consisted of 286 adults with ASD (mean age 39.5 +/- 19 years). All patients had >or = 1 follow-up visit and a Doppler echocardiographic study. One hundred ninety-two of the patients underwent surgical closure 1 to 34 years before the study. Analyzed variables were entered into univariate (Mann-Whitney U) and multivariate (stepwise logistic regression) models to assess independent predictors for AF. The prevalence of AF was similar in surgically treated patients (15.6%) and in the nonsurgical group (13.8%) (p = 0.69). Multivariate analysis showed that current age (RR 1.9 per each decade of age, 95% confidence interval [CI] 1.3 to 2.7, p = 0.001), mitral regurgitation (RR 3.0 per each degree of regurgitation, 95% CI 1.6 to 5.8, p = 0.001), left atrial enlargement (RR 2.8 per each 10 mm increase in size, 95% CI 1.5 to 5.2, p = 0.001), and tricuspid regurgitation (RR 1.9 per each degree of regurgitation, 95% CI 1.0 to 3.7, p = 0.04) were independent predictors of AF; however, gender, anatomic type, defect size, Qp:Qs, pulmonary artery pressure, right ventricular dimension, left ventricular shortening fraction, and prior surgical repair were not related to late AF development. In the surgical group, age >25 years at the time of surgery was the only predictor for AF independent of age at the time of the study (p = 0.02).
