ABSTRACT
@#Objective To investigate the clinical efficacy and application value of percutaneous interventional treatment for structural heart diseases under guidance of ultrasound. Methods The clinical data of 1 010 patients with structural heart diseases treated by transcutaneous ultrasound-guided occlusion in our hospital from December 2, 2015 to December 31, 2019 were retrospectively reviewed, including 360 males and 650 females, aged 1-50 years. There were 692 patients of atrial septal defect (603 with central type, 9 combined with arterial catheter, 80 with ethmoid type), 116 patent foramen ovale, 25 ventricular septal defects (3 combined with atrial septal defect), 132 patent ductus arteriosus, 32 pulmonary valve stenosis (3 combined with atrial defect), 1 main pulmonary artery window, and 3 aneurysm rupture of aortic sinus. All patients were diagnosed by transthoracic echocardiography (TTE) before operation. Treatment was accomplished intraoperatively through TTE or transesophageal echocardiography (TEE) via the femoral artery or femoral vein. After operation, echocardiography, electrocardiogram and chest radiograph were reexamined. Results Satisfactory results were obtained in 1 005 patients, and 1 patient failed to seal the ventricular defect and was repaired under direct vision, occluder detachment occurred in 5 patients after operation (3 patients of atrial septal defects underwent thoracotomy for Amplatzer device and were repaired, 1 patient of atrial septal defects was closed after removing Amplatzer device, 1 patient of patent ductus arteriosus underwent thoracotomy for Amplatzer device and was sutured), mild pulmonary valve regurgitation occurred after balloon dilation in 2 patients with pulmonary stenosis, a small amount of residual shunt was found in 2 patients with ventricular defect, which disappeared after 3 months of follow-up, and 1 patient of right bundle branch block occurred and disappeared after 1 week. After follow-up of 1-24 months, 3 patients of ethmoidal atrial septal defect were reexamined with mild shunt. The occluder was in good position and the pressure difference of pulmonary valve was significantly reduced. There was no complication such as hemolysis, arrhythmia, embolism or rupture of chordae tendinae. Conclusion Percutaneous transfemoral artery and vein guided by TTE or TEE is safe and effective, with little trauma, no radiation or contrast agent damage, and has significant clinical efficacy and application values.
ABSTRACT
Resumen La red sanitaria en el entorno de la pandemia por COVID-19 ha sufrido un gran impacto. La reorganización de la misma ha sido fundamental para poder atender la emergencia sanitaria, y en algunos países, ha sido incluso de forma abrupta. La atención oportuna de las enfermedades cardiovasculares continúa siendo una prioridad por la elevada mortalidad que ella implica especialmente en estadios muy avanzados de la enfermedad, y la modificación en la atención médica en el contexto actual no puede afectar la asistencia de patologías cardíacas. Los programas de cardiología estructural y cirugía cardíaca en nuestro país se han consolidado y crecido en los últimos años, ofreciendo múltiples procedimientos percutáneos o mínimamente invasivos para cardiopatías de alta morbimortalidad. La continuación de los mismos, a pesar de las dificultades por la pandemia, es necesaria en ciertos casos. Este documento reúne las principales recomendaciones basados en textos internacionales al respecto, para mantener el cuidado cardiovascular en Costa Rica pese al COVID-19 en el ámbito de la cardiopatía estructural.
Abstract The health system in the context of the COVID-19 pandemic has suffered a great impact. Thus, organization has been essential in maintaining the ability to respond to the health emergency, and in some countries, it has even been abrupt. The treatment of cardiovascular diseases continues to be a priority, and the modification of medical care in the current context cannot affect the timely procedures of cardiac pathologies. The structural cardiology and cardiac surgery programs in our country have been consolidated and grown in recent years, offering multiple percutaneous or minimally invasive procedures for heart disease with high morbidity and mortality. Their continuation, despite the difficulties caused by the outbreak, is necessary in certain cases. This document brings together the main recommendations based on international guidelines and experts opinions in this regard, to maintain cardiovascular care in Costa Rica despite COVID-19.

Abstract Objective: Cardiac sympathetic denervation (CSD) using video-assisted thoracoscopy is a therapeutic alternative for cardiac arrhythmias refractory to conventional treatment in patients with ventricular structural heart disease, mainly due to ischemia, and in patients with hereditary conditions associated with sudden death such as long QT syndrome. In general, it is performed in cases with recurrent episodes of ventricular tachycardia or electrical storm, in spite of conventional treatment. The objective of this study is to show the experience of this institution with DSCI in refractory patients to conventional management and the results derived from its application. Methods: This was an observational retrospective study. The records of patients with a history of ventricular arrhythmias treated in our center with pharmacological treatment, catheter ablation, or implantation of an implantable cardioverter-defibrillator (ICD), who underwent video-assisted CSD were analyzed and described. Results: A total of six patients were included in the study. Patients with structural heart disease were the most frequent, median age was 56 � 16 years; 67% were male. The procedure evolved without complications in any of the patients and an overall significant improvement was observed. A 24-month follow-up was conducted; two patients had recurrence episodes presenting as slow ventricular tachycardia without severe symptoms and a third patient presented an episode of ventricular fibrillation aborted by the ICD. Conclusion: Video-assisted CSD should be considered as a treatment option for patients with potentially dangerous arrhythmias that do not respond to conventional treatment, especially in recurrent ventricular tachycardia.
Resumen Objetivo: La denervación simpática cardiaca izquierda (DSCI) por toracoscopia se ha convertido en una alternativa terapéutica para el manejo de arritmias cardíacas refractarias al tratamiento convencional en pacientes con cardiopatía estructural, principalmente isquémicos, y enfermedades hereditarias asociadas con muerte súbita como el síndrome de QT largo. Generalmente se realiza en quienes manifiestan episodios recurrentes de arritmias ventriculares o incluso tormenta eléctrica a pesar del tratamiento convencional. El objetivo de este estudio es mostrar la experiencia de esta institución con la DSCI en pacientes refractarios al manejo convencional y los resultados derivados de su aplicación. Métodos: Se revisaron los registros de 6 pacientes con antecedente de arritmias ventriculares tratados previamente con medicamentos y en algunos casos con ablación con catéter y la mayoría con desfibrilador automático implantable, que fueron llevados DSCI por toracoscopia video-asistida (VATS). Resultados: La principal enfermedad de base fue la cardiopatía estructural, la indicación más prevalente fue tormenta arrítmica incontrolable, la edad promedio fue de 56 +- 16 años, el 67% de los individuos fueron hombres. Este procedimiento no mostró complicaciones en ninguno de los pacientes y se encontró mejoría sintomática en todos los casos. Se realizó seguimiento por 24 meses; dos pacientes tuvieron recurrencias por taquicardia ventricular lenta sin síntomas severos y uno por fibrilación ventricular. Conclusion: La DSCI por VATS debe considerarse como opción terapéutica para pacientes con arritmias de difícil manejo.

@#Congenital heart disease refers to the structural or functional abnormality of the macrovascular in the heart or thoracic cavity caused by the failure of the formation of the heart and large blood vessels during the embryonic development or the abnormal closure of the heart or the closure of the channel after birth. In the past few years, a new and broader definition of structural heart disease has been gradually proposed. Structural heart disease narrowly refers to the pathological and physiological changes of the heart caused by abnormal anatomical structures in the heart, including congenital heart disease. A few decades ago, congenital heart disease was considered as a pediatric disease, because most patients with severe lesions rarely survive to adulthood. Due to recent advances in echocardiography, anesthesia, intensive care, percutaneous intervention, especially cardiac surgery in recent decades, the treatment and intervention strategies for congenital heart disease in children have been greatly improved, a fatal defect in childhood can now be successfully repaired or alleviated. Because of these successes, more than 90% of congenital heart disease patients are expected to survive to adulthood, which has led to emerge a new population: adult patients with congenital heart disease. Adult congenital heart disease patients are different from children. Pulmonary hypertension leads to right heart failure and eventually progresses to whole heart failure. The appearance of Eisenmenger syndrome leads to severe cyanosis and worsening of the disease. At present, the continuous development of mechanical assisted circulation support devices and heart or cardiopulmonary transplantation technology has increased the survival rate of end-stage adult congenital heart disease patients with heart failure. The high incidence of cardiovascular events in pregnant patients requires comprehensive multidisciplinary team care and early coordination planning for delivery, including early counseling for pregnancy-related risks, close monitoring of cardiac function and regular scan of fetal assessment. The prenatal and postpartum integrated diagnosis and treatment model and the development of intrauterine treatment technology reduce the incidence of congenital heart disease in adults from the source through fetal intervention. Other complications such as arrhythmia, infective endocarditis, cerebrovascular accidents, and other medical underlying metabolic diseases also challenge future diagnosis and treatment. The incidence and epidemiology of adult congenital heart disease, pulmonary hypertension and end-stage heart failure complications, as well as prenatal and postpartum integrated diagnosis and treatment and intrauterine treatment are summarized in this review.

The topics include the applications of 3DE in valvular disease and congenital heart disease, etc. The techniques used are ranging from transthoracic and transesophageal adult 3DE imaging to belly fetal echocardiography; from disease diagnosis to selection of device before interventional therapy, monitoring during processing and evaluation of postoperative efficiency; from detection of cardiac structure to 3D printing of the heart, showing the application status and prospect of 3DE.
ABSTRACT
Methylmalonic acidemia is the most common disease of congenital organic acid metabolic disorders,and it is an autosomal recessive disease.The clinical manifestations of methylmalonic acidemia are non-specific.It is characterized by the neurological symptoms.Cardiovascular diseases have little been associated with methylmalonic acidemia.But,cardiovascular diseases including structural heart disease,pulmonary hypertension,cardiomyopathy,hypertension,arrhythmias,may cause rapid deterioration,or even sudden death.This paper is a review of cardiovascular diseases of methylmalonic acidemia.
ABSTRACT
Structural heart disease includes congenital cardiovascular structural abnormalities, valvular heart disease and cardiomyopathy, which shows the common features of cardiac anatomical structure and hemodynamic abnormalities, especially anatomical abnormalities. Echocardiography, especially three-dimensional (3D) ultrasound, is good at displaying anatomical structure and blood flow abnormalities. As a non-invasive method of examination, it has advantage in the evaluation of such heart diseases. In recent years, the gradual rise of 3D printing technology can make physical printing, and the printed heart model can stereoscopically display abnormal state of heart diseases. Ultrasound combined with 3D printing technology may provide more intuitive and accurate information for the assessment of structural heart disease.
ABSTRACT
Background: Structural Heart Disease (SHD) is a preventable cause of mortality. As age advances the morbidity rates due to SHD increases. SHD is more common in rural areas and lower socio-economic status because of poor hygiene and poor nutrition. The aim of this study was to find the incidence of heart disease in a male north Indian population. Method: A team consisting of three doctors examined all the candidates presenting over a period of one and a half years for enrollment at a particular Centre. The age group of this population was between 18 years to 22 years. All candidates underwent medical examination. Candidates having suspicion of SHD were referred to the physician/cardiologist. All those persons whose disability was within permissible limits were taken as fit and the others were taken as unfit. Results: Total 4223 candidates reported in the above period. 334 candidates who had disabilities were lost to follow-up and excluded, leaving a total of 3889 candidates. After specialist review, 1471 candidates were found unfit for various causes, out of which 283 were for cardiac murmurs. Many candidates were found to be suffering from multiples disabilities. Conclusion: Our study found an incidence rate of 72.7 per thousand which is much higher than that of other studies. The possible reasons for this could be that the persons are primarily from rural background and low socioeconomic strata which have a comparatively incidence of SHDs. Also contributing to the higher incidence may be the fact of stricter application of physical standards for enrollment in the army.
ABSTRACT
Objective To investigate the diagnostic value of preoperative real-time three-dimensional color Doppler transthoracic echocardiography on assessment of patients with structural heart disease (SHD). Methods A total of 111 pa?tients were assessed preoperatively using real-time three-dimensional color Doppler transthoracic echocardiography (RT-3D-CDTTE), which include 31 SHD patients and 80 patients without SHD that were designed as negative control. Conven?tional two-dimensional color Doppler transthoracic echocardiography (2D-CDTTE) were used to compared with RT-3D-CDTTE while cardiovascular angiography and intraoperative findings were used as“Golden Standard”simultaneously. First of all, preoperative echocardiographic examination were performed and diagnosis was given. Angiography and intraoperative findings were hired to verify the accuracy of echocardiographic diagnosis before operation. Results (1) The preoperative RT-3D-CDTTE displayed three-dimensional structure and hemodynamic status of SHD cardiac lesions clearly, which were consistent with cardiovascular angiography and intraoperative findings. (2) P value of McNemar test between 2D-CDTTE and“Golden Standard”was greater than 0.05, Kappa=0.654 (P<0.001). P value of McNemar test between RT-3D-CDTTE and“Golden Standard”was greater than 0.05, Kappa=0.932 (P<0.001). Conclusion RT-3D-CDTTE can provides essen?tial information for preoperative evaluation which is important for decision of SHD management.
ABSTRACT
Structural heart diseases refer to anatomic heart or great vessels abnormalities by congential or acquired factors, including congenital heart disease, acquired heart valve disease, cardiomyopathy. In recent years, interventional therapy in structural heart diseases has gradually matured and been widely applied in clinical practice. Due to the fragility of heart valves and valve related organizations, or the congenital dysplasia of valves, the complex interventional therapeutic procedures can cause valve-related complications. In this paper, the causes, prevention and treatment of valve-related complications induced by interventional therapy in structural heart diseases are introduced.
ABSTRACT
BACKGROUND: Radiofrequency catheter ablation therapy of idiopathic ventricular tachycardia in patients without obvious structural heart disease has been assessed in a few studies, but the clinical feasibility and efficacy are not certain. This study reports our results of catheter ablation with radiofrequency energy in thirteen patients. METHODS: Thirteen consecutive patients with idiopathic ventricular tachycardia underwent electrophysiologic study, pharmacological interventions and radiofrequency catheter ablation therapy. RESULTS: There were 7 men and 6 women with a mean age of 34+/-11years(13-55 years). The QRS configuration during tachycardia were left bundle branch block and inferior axis in 5 patients, right axis in 1 patient and right bundle branch block configuration with superior axis in 4 patients, right axis in 2 patients, left axis in 1 patients. Mean tachycardia cycle length was 361 +/-20 milliseconds. The focus of ventricular tachycardia were located in the right ventricular outflow tract(six patients) and the left ventricular inferior wall(four patients), posterobasal wall(one patients), anterolateral wall(one patients). Ventricular tachycardias were electrically induced in 9/13 patients. Mapping and radiofrequent catheter ablation was done with standard technique and ventricular tachycardia or VPCs were successfully eliminated in nine patients(69.2%). One patients complicated with transient pleural effusion. During mean follow-up period of 12+/-3months, one patients had a recurrence of symptomatic ventricular tachycardia. CONCLUSION: Radiofrequency catheter ablation of ventricular tachycardia in patients without structural heart disease is effective and safe and may be considered as primary choice of therapy in the patients.
