RESUMO
INTRODUCTION: Atrial septal defect (ASD) is one of the most common congenital heart malformations. Although not recommended, a significant proportion of patients with aortic root defects receive ASD closure, some of whom have improved right ventricular function. The study aimed to investigate the safety of interventional therapy in ASD patients with complete aortic rim deficiency and explore the predictors of right atrial (RA) non-reverse remodeling. METHODS: 1,011 patients with ASD who underwent transcatheter closure in the Department of Cardiology, Zhongshan Hospital, affiliated to Fudan University from June 2017 to June 2023 were enrolled in the study. They were divided into a complete aortic rim deficiency group and without absent aortic rim group. Furthermore, patients who had an enlarged RA in the absent aortic rim group were divided into two subgroups according to whether their RA remodeling was reversed post-procedure. Multivariate logistic regression was used to determine the predictors of RA reverse remodeling. RESULTS: During the 1-year follow-up, no major operative complications occurred in all patients with the absence of an aortic rim and a normal edge. After the operation, the right heart remodeling was significantly reversed, multivariate logistic regression analysis was performed, and it was found that no coronary heart disease before an operation, lower plasma creatinine level, and larger RA and RV dimensions were the predictive factors for the reverse of RA remodeling after treatment. CONCLUSION: Transcatheter closure of ASD with complete aortic rim deficiency is safe and feasible. For patients without coronary heart disease, the lower the creatinine value and the lower the tricuspid regurgitation before an operation, the more improvement of RA remodeling after the operation.
RESUMO
Tricuspid regurgitation (TR) may occur late after left-sided valve surgery (LSVS). Isolated tricuspid regurgitation after left-sided valve surgery (iTR-LSVS) refers to isolated TR without significant lesions in the mitral and/or aortic position late after mitral and/or aortic replacement or repair. Severe TR has a negative impact on long-term prognosis and requires surgical or transcatheter treatment. However, there is no clear recommendation on when and how intervention should be performed for patients with iTR-LSVS in the current guidelines for the management of valvular heart disease. The historically high operative mortality may be reduced by current minimally invasive techniques and transcatheter therapy. To further understand iTR-LSVS, standardize the treatment, improve the prognosis, and promote the collaboration, the Chinese Minimally Invasive Cardiovascular Surgery Committee (CMICS) wrote this expert consensus on the management of iTR-LSVS from the aspects of etiology, preoperative evaluation, indications for intervention, surgical treatment, transcatheter therapy, and postoperative management.
RESUMO
Mitral regurgitation (MR) is one of the most prevalent types of valvular heart disease and is expected to increase in the next decade. Transcatheter therapies for MR are constantly being developed and studied for use in this population. In this review, the author describes the phenotypes of functional or secondary mitral regurgitation, discusses the potential therapeutic targets for transcatheter intervention, and reviews the results of such technology in the literature.

Both the MitraClip and PASCAL systems offer transcatheter edge-to-edge repair (TEER) solutions for mitral regurgitation. Evidence indicates a lower technical success rate for TEER in complex degenerative mitral regurgitation (DMR) cases. We conducted a retrospective analysis of patients who underwent transcatheter edge-to-edge therapy for primary mitral regurgitation with advanced anatomy, defined as mitral regurgitation effective regurgitant orifice area (MR-EROA) ≥0.40 cm2 or large flail gap (≥5 mm) or width (≥7 mm) or Barlow's disease, that completed follow-up after 1 year. Our criteria were met by 27 patients treated with PASCAL and 18 with MitraClip. All patients exhibited a significant, equivalent short-term reduction in MR-EROA, mitral regurgitation vena contracta diameter (MR-VCD), regurgitant volume, and clinical status. At 1 year follow-up, reductions in MR-VCD, regurgitant volume, and MR-EROA remained significant for both groups without significant differences between groups. MR-Grade ≤ 1+ was achieved in 18 (66.7%) and 10 (55.6%) patients, respectively. At follow-up, no difference in hospitalization for cardiac decompensation was observed. Overall death was similar in both groups. Our study suggests that both the PASCAL and MitraClip systems significantly reduce mitral regurgitation even in advanced degenerative diseases. Within our limited data, we found no evidence of inferior performance of the PASCAL system.
RESUMO
BACKGROUND: Tricuspid valve transcatheter edge-to-edge repair (T-TEER) is the most widely used transcatheter therapy to treat patients with tricuspid regurgitation (TR). OBJECTIVES: The aim of this study was to develop a simple anatomical score to predict procedural outcomes of T-TEER. METHODS: All patients (n = 168) who underwent T-TEER between January 2017 and November 2022 at 2 centers were included in the derivation cohort. Additionally, 126 patients from 2 separate institutions served as a validation cohort. T-TEER was performed using 2 commercially available technologies. Core laboratory assessment of procedural transesophageal echocardiograms was used to determine septolateral and anteroposterior coaptation gap, leaflet morphology, septal leaflet length and retraction, chordal structure density, tethering height, en face TR jet morphology and TR jet location, image quality, and the presence of intracardiac leads. A scoring system was derived using univariable and multivariable logistic regression. Endpoints assessed were immediate postprocedural TR reduction ≥2 grades and TR grade moderate or less. RESULTS: The median age was 82 years (Q1-Q3: 78-84 years); 48% of patients were women; and patients presented with severe (55%), massive (36%), and torrential (8%) TR. Five variables (septolateral coaptation gap, chordal structure density, en face TR jet morphology, TR jet location, and image quality) were identified as best predicting procedural outcome and were incorporated in the GLIDE (Gap, Location, Image quality, density, en-face TR morphology) score (range 0-5). TR reduction ≥2 grades and TR grade moderate or less were observed in >90% of patients with GLIDE scores of 0 and 1 and in only 5.6% and 16.7% of those with GLIDE scores ≥4. The GLIDE score was then externally validated in a separate cohort (area under the curve: 0.77; 95% CI: 0.69-0.86). TR reduction significantly correlated with functional improvement assessed by NYHA functional class and 6-minute walk distance at 3 months. CONCLUSIONS: The GLIDE score is a simple, 5-component score that is readily obtained during patient imaging and can predict successful T-TEER.

Introducción: El secuestro pulmonar (SP) ha sido tratado por muchos años con cirugía convencional efectuando remoción del tejido pulmonar ectópico y ligadura de los vasos sanguíneos aberrantes que nacen desde la aorta. Existe evidencia establecida, especialmente en literatura de habla inglesa que apoya el uso de la embolización arterial transcatéter mediante dispositivo para ocluir el vaso anómalo, como una opción de tratamiento seguro y definitivo para el SP intralobar. Objetivo: Mostrar nuestra experiencia pionera de la técnica de tratamiento del SP por medio de embolización transcatéter. Caso clínico: Presentamos los casos clínicos de dos adolescentes, de 13 y 14 años y de un recién nacido de 26 días de vida, portadores de SP intralobar, cuyos diagnósticos se realizaron a través de Tomografía Axial Computarizada (TAC) con contraste, tratados mediante embolización arterial transcatéter, con buen resultado y sin complicaciones en el seguimiento precoz y tardío. Conclusión: Con este tratamiento se logra en los pacientes afectados de SP resultados definitivos, menos invasivos y sin complicaciones al seguimento.
Introduction: Pulmonary sequestration (PS) has been treated for many years with conventional surgical removal of the ectopic lung tissue and ligation of aberrant vessels that arise from the aorta. There is evidence, especially in English-language literature that supports the use of transcatheter arterial embolization through a device for occlusion of the anomalous vessel, as a safe option and definitive treatment for intralobar PS. Objective: To show our experience pioneering the technique of PS treatment through transcatheter embolization. Case report: The case reports of two teenagers aged 13 and 14 and a 26-day-old newborn that developed intralobar PS are described. The diagnosis was made through computerized axial tomography (CT scan) and successfully and without complication, during early and long term follow-up, treated by arterial embolization transcatheter. Conclusion: The use of transcatheter arterial embolization is a less invasive and definitive treatment for patients with PS.
