In recent years, with the continuous development and increasing maturity of interventional techniques, interventional treatment for congenital heart disease (CHD) has been progressively disseminated to county- and city-level hospitals in China. Concurrently, the standardized management of adult CHD (particularly patent foramen ovale) and the lifelong management of complex CHD are gaining increasing clinical attention, while the emergence of new techniques and products continuously advances the discipline. This article aims to review the new progress made in the field of interventional treatment for congenital heart disease in China during 2024. It specifically reviews and analyzes the following key aspects: (1) annual statistics on interventional closure procedures for CHD; (2) recent insights into patent foramen ovale closure; (3) advances in transcatheter pulmonary valve replacement; (4) interventional treatment and lifelong management strategies for complex CHD; (5) new interventional techniques for acquired heart disease; and (6) the application of artificial intelligence in CHD management. Through the synthesis and discussion of these topics, this article seeks to provide a detailed analysis of the current landscape of interventional treatment for CHD in China and project its future development trends.

Objective To investigate the clinicopathological and prognostic characteristics of intestinal inflammatory myofibroblastic tumours(IMT)in middle-aged and elderly patients.Methods The clinical,pathologi-cal morphology,immunophenotype and follow-up results of 5 cases of intestinal IMT in middle-aged and elderly patients were retrospectively analyzed.Results 4 cases of IMT occurred in the right half colon and 1 in the ileum.Most patients(3/5)had a history of intestinal injury,starting the digestive tract symptoms and increased leukocytes.The tumor tissue was composed of fusiform myofibroblasts and fibroblasts arranged in storiform pattern,with an infiltrative growth pattern,accompanied by a large number of lymphocytes and plasma cells infiltration,collagen formation and myxedema.One case was atypically large and deformed.Immunophenotype:vimentin(5cases),SMA(5 cases),desmin(3 cases),ALK(3 cases),CK(2 cases)were positive.Caldesmon,CD34,β-catenin,MC,CD117,DOG1,S-100,BCL-2,CD99,CD68 were negative,and Ki-67 proliferation index was 1.28%to 10.01%.All the 5 cases underwent complete tumor resection and were followed up for 48.5 to 133 months.Among them,1 patient aged 83 was considered to have tumor recurrence 27 months after surgery.The other patient survived 122 months without tumor and died of other causes.All the others survived without tumor and were in good condition.Conclusion(1)Intestinal IMT in the middle-aged and elderly people in this group was more common in the right half colon,and most of them had a history of intestinal injury,first gastrointestinal symptoms and elevated white blood cells;(2)Vimentin and SMA were positive at the same time,and ALK was more positive;(3)4/5 patients had good surgical resection,and 1/5 patients could relapse 2～3 years after surgery;old age,ALK-positive,Ki67 up to 10%,atypia may be an important risk factor for intestinal IMT recurrence in the elderly,of which ALK-positive patients may have a recurrence risk of 1/3.

A domestically produced self-expanding transcatheter aortic valve controllable bending delivery system(VitaFlow? Ⅲcontrollable bending retrievable delivery system)was first used to perform transcatheter aortic valve replacement(TAVR)in a symptomatic severe aortic valve stenosis patient with severe heart failure and high risk of surgery in China on September 22,2023.The patient successfully completed TAVR under general anesthesia,with good valve position and function after the operation.Before discharge and at one month of follow-up,the patient's symptoms and degree of heart failure were significantly improved.The follow-up results of this case showed that the VitaFlow? Ⅲ controllable bending retrievable delivery system for TAVR is safe and feasible,and future prospective,multicenter clinical trials are expected to evaluate its efficacy.

Aortic stenosis is a valve disease characterized by dynamic and continuous changes in structure and function of left ventricle.Left ventricular remodeling,which embodies pathological changes in myocardial cellular and ventricular geometry,is an important prognostic factor of patients with aortic stenosis.Aortic valve replacement is the only effective treatment for severe aortic stenosis.Current guideline recommendations for interventions are based on symptoms and left ventricular ejection fraction.With the improvements of modern imaging technology,different patterns of remodeling,including hypertrophy and fibrosis,could be identified now.Studies also explored the close association between left ventricular remodeling and function in the setting of aortic stenosis.In this review,we aim to elucidate the characteristic imaging features and potential mechanisms of left ventricular remodeling,and further,we highlight the clinical value of specific imaging features and clinical application of modern imaging methods in the evaluation,risk stratification,and intervention decision-making for patients with aortic stenosis.

Objective To investigate the effect and mechanism of Panax notoginseng saponins(PNS)in inhibiting c-Jun N-terminal protein kinase(JNK)/c-Jun signaling pathway activation to alleviate calcific aortic valve disease(CAVD)in mice.Methods Twenty-one male ApoE-/-mice aged 6 to 8 weeks were randomly divided into the model,PNS high-dose(60 mg/kg),and PNS low-dose(30 mg/kg)groups using the random number table method,with seven mice per group.Nine male C57BL/6 mice aged 6 to 8 weeks were used as the control group.Mice in the control group were fed a normal diet,whereas ApoE-/-mice were fed a high-fat diet for 12 weeks.After 12 weeks,three C57BL/6 and three ApoE-/-mice(one ApoE-/-mice from each group)were randomly selected to evaluate the CAVD modeling effect.After confirming successful modeling,the PNS high-and low-dose groups received daily intragastric PNS administration.The control and model groups were administered an equal volume of stroke-physiological saline solution by gavage for 4 consecutive weeks.The valve annulus diameter and peak velocity of the mice in each group were then detected using ultrasound.The degree of aortic valve calcification was evaluated using von Kossa and Alizarin Red S staining.The serum triglycerides(TG),total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C),and high-density lipoprotein cholesterol(HDL-C)were detected by biochemical method.Inflammatory factor interleukin-4(IL-4),tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),and interleukin-10(IL-10)levels were determined using an enzyme-linked immunosorbent assay.The expressions of calcification markers,runt-related transcription factor 2(RUNX2),and bone morphogenetic protein 2(BMP2)were detected using immunohistochemistry.Aortic valve cell apoptosis was evaluated using TUNEL staining,and JNK/c-Jun signaling pathway-related mRNA and mean fluorescence intensity were detected using quantitative real-time PCR and immunofluorescence,respectively.Results Compared with the control group,the mice in the model group showed an increase in serum TC,TG,LDL-C,TNF-α,and IL-1β levels,a decrease in IL-4 and IL-10 levels,a decrease in annulus diameter,an increase in peak flow velocity,and an increase in von Kossa and Alizarin Red S staining-positive areas.Additionally,the model group showed an increase in aortic valve cell apoptosis rate,an increase in BMP2 and RUNX2-positive rates,and an increase in JNK and c-Jun mRNA expression levels and p-JNK/JNK and p-c-Jun/c-Jun(P<0.05).Compared to the model group,the PNS low-dose group showed a decrease in serum TC,LDL-C,and TNF-α levels,an increase in annulus diameter,a decrease in peak flow velocity,and a decrease in positive area in Alizarin Red S staining.Furthermore,the PNS low-dose group showed a decrease in BMP2 and RUNX2-positive rates,JNK and c-Jun mRNA expression levels,and p-JNK/JNK and p-c-Jun/c-Jun(P<0.05).The PNS high-dose group showed an increase in HDL-C,IL-4 and IL-10 levels,a decrease in serum TC,LDL-C,TNF-α,and IL-1β levels,an increase in annulus diameter,a decrease in peak flow velocity,and a decrease in von Kossa and Alizarin Red S staining-positive areas and cell apoptosis rate.The PNS high-dose group also showed a decrease in BMP2 and RUNX2 positive staining rates,JNK and c-Jun mRNA expression levels,and p-JNK/JNK and p-c-Jun/c-Jun(P<0.05).Conclusion PNS may reduce valvular cell apoptosis,alleviate inflammation,and protect against aortic valve calcification in mice by inhibiting the activation of JNK/c-Jun signaling pathway.
