Ventricular septal defect complicating acute myocardial infarction: diagnosis and management. A Clinical Consensus Statement of the Association for Acute CardioVascular Care (ACVC) of the ESC, the European Association of Percutaneous Cardiovascular Interventions (EAPCI) of the ESC and the ESC Working Group on Cardiovascular Surgery.

Ventricular septal defects are a rare complication after acute myocardial infarction with a mortality close to 100% if left untreated. However, even surgical or interventional closure is associated with a very high mortality and currently no randomized controlled trials are available addressing the optimal treatment strategy of this disease. This state-of-the-art review and clinical consensus statement will outline the diagnosis, hemodynamic consequences and treatment strategies of ventricular septal defects complicating acute myocardial infarction with a focus on current available evidence and a focus on major research questions to fill the gap in evidence.

Value of echocardiography for mini-invasive per-atrial closure of perimembranous ventricular septal defect.

The purpose of this study was to assess the value of echocardiography for intraoperative guidance during closure of perimembranous ventricular septal defects (pmVSD) and to assess outcomes of these patients. We identified and assessed 78 patients who underwent 2- and 3-dimensional echocardiography-guided mini-invasive per-atrial closure of pmVSD in the cardiac surgery department of our institution, from February 2016 to August 2018, and 76 patients who underwent transcatheter closure of VSD guided by fluoroscopy at the pediatric department (percutaneous control group). All the patients underwent echocardiography. Their clinical data were retrospectively reviewed and analyzed. All patients were followed up using transthoracic echocardiography (TTE) for a maximum of 24 months after the closure. All patients underwent successful device implantation. Echocardiography showed that the major immediate complications included residual shunt, pericardial effusion, and tricuspid regurgitation in the per-atrial group. During the mid-term follow-up period, TTE revealed that the most common complication was tricuspid regurgitation (non-preexisting). There were no cases of VSD recurrence, device displacement, valvular injury, malignant arrhythmias, hemolysis, or death. Moreover, according to the TTE data, the intracardiac structure of the patients were improved. Compared to the control group, the intracardiac manipulation time was shorter and the number of patients with residual shunts, redeployment of devices, or immediate new tricuspid regurgitations was fewer when using 2- and 3-dimensional echocardiography. However, the procedure time in the per-atrial group was slightly longer than that in the control group. Two- and 3-dimensional echocardiography are feasible monitoring tools during mini-invasive per-atrial VSD closure. The short- and mid-term follow-up showed satisfactory results compared to fluoroscopy.

Exercise Capacity and Ventricular Remodeling After Transcatheter Ventricular Septal Defect Closure in Asymptomatic or Minimally Symptomatic Adolescents and Adults.

BACKGROUND: Transcatheter ventricular septal defect (VSD) closure is a safe and efficacious alternative to surgery. However, its benefits in asymptomatic or minimally symptomatic patients remain unknown. METHODS: Sixty patients with VSD aged 12 to 60 years underwent cardiopulmonary exercise test and echocardiography 1 day before transcatheter VSD closure and 6 months after intervention (closure group). Thirty patients who did not receive the intervention underwent the same evaluations over 6 months (observation group). RESULTS: No significant change in exercise function was observed after VSD closure, except for increased peak oxygen (O2) pulse (absolute increase: 0.4±1.4 mL/beat). Left ventricular end-diastolic dimension and mitral peak early filling velocity-to-early diastolic annular velocity ratio decreased (absolute decrease: 0.3±0.6 cm and 0.7±1.9, respectively). Despite unchanged overall peak O2 consumption, 33% of closure group patients exhibited clinically significant improvements in peak O2 consumption (>10% increase relative to baseline). This was not related to the pulmonary flow-to-systemic flow ratio or baseline exercise capacity. By contrast, all exercise function parameters deteriorated significantly in the observation group. Subgroup analysis revealed that patients with a baseline left ventricular end-diastolic dimension Z score of >2 exhibited a significantly greater improvement in peak O2 consumption, peak O2 pulse, and oxygen uptake efficiency slope than did the observation group. CONCLUSIONS: Compared with conservative management, transcatheter VSD closure prevents deterioration in exercise capacity and promotes left ventricular reverse remodeling in asymptomatic or minimally symptomatic patients. These benefits are most prominent in patients whose left ventricular end-diastolic dimension Z score before intervention is >2, irrespective of baseline peak O2 consumption and pulmonary flow/systemic flow ratio.

Outcomes of closure of doubly committed subarterial ventricular septal defects in adults.

BACKGROUND: Outcome data of doubly committed subarterial ventricular septal defect closure in adults are limited. METHODS: A review was made of the inpatients >18 years of age who underwent doubly committed subarterial ventricular septal defect closure between June 2010 and June 2017. RESULTS: The patients were categorised into two groups: The valve intervention group consisted of 31 patients who underwent aortic valvuloplasty, aortic valve replacement, or repair of sinus Valsalva aneurysm in addition to doubly committed subarterial ventricular septal defect closure; non-valvular intervention group comprised 58 patients who underwent only doubly committed subarterial ventricular septal defect closure. The groups did not differ by sex and age. Patients in the valve intervention group, with a larger ventricular septal defect size, were shorter and tended to be lighter. The valve intervention group had more patients with pneumonia perioperatively. No infective endocarditis and reoperation were noted during the study period. At last follow-up, 91 and 96.6% of the studied patients were free from left ventricle dilation and pulmonary hypertension. In patients without pre-operative aortic regurgitation, 12 developed new mild aortic regurgitation during the follow-up. CONCLUSIONS: About 34.8% of adult patients with doubly committed subarterial ventricular septal defect required concurrent intervention on aortic valve or sinus Valsalva aneurysm. The midterm results of doubly committed subarterial ventricular septal defect closure in adult patients were favourable. However, the incidence of new mild aortic regurgitation after ventricular septal defect closure was high (27.3%). Long-term follow-up of aortic regurgitation progression is needed.

[Clinical effect of feeding with calorie-enriched formula in children with ventricular septal defect and severe pneumonia].

OBJECTIVE: To study the effect of different energy feeding patterns on the nutritional status, clinical course, and outcome of children with congenital heart disease (CHD) and severe pneumonia. METHODS: A total of 43 malnourished infants, aged <6 months, who were diagnosed with ventricular septal defect and severe pneumonia and underwent surgical operation from January 1 to December 30, 2017 were enrolled. They were randomly divided into an observation group with 21 infants and a control group with 22 infants. The infants in the observation group were given calorie-enriched formula milk powder (100 kcal/100 mL) after surgery, and those in the control group were given formula milk powder with normal calories (67 kcal/100 mL). The two groups were observed for 3 months to record physical measurements, laboratory markers and nutritional risk screening results. Nutritional status was evaluated for all infants. The two groups were compared in terms of prognosis and adverse events. RESULTS: There were no significant differences between the two groups in physical measurements, laboratory markers, nutritional assessment and nutritional risk screening results on admission (P>0.05). At discharge and 1 and 3 months after surgery, the control group had significantly higher degree of malnutrition and level of nutritional risk than the observation group (P<0.05). The analysis of variance with repeated measures showed significant differences in body weight, upper arm circumference, weight-for-age Z-score, height-for-age Z-score, weight-for-height Z-score, and albumin level at different time points and between different groups, and there was an interaction between group factors and time factors (P<0.05). Compared with the control group, the observation group had a significantly lower average daily intake of fluid, a significantly higher average daily intake of energy, and a significantly lower incidence rate of insufficient feeding during hospitalization (P<0.05). Compared with the control group, the observation group had significantly shorter length of hospital stay, duration of mechanical ventilation, and duration of postoperative pyrexia, as well as significantly lower hospital costs (P<0.05). No significant adverse reactions were observed in either group. CONCLUSIONS: An appropriate increase in postoperative energy supply for children with CHD can improve the status of malnutrition and clinical outcome.

Hemolysis and its outcome following percutaneous closure of cardiac defects among children and adolescents: a prospective study.

BACKGROUND: Transcatheter closure of intracardiac defects might be complicated by intravascular hemolysis. We evaluated hemolysis and its outcome after transcatheter closure of these defects. METHODS AND PATIENTS: All patients who underwent transcatheter closure of patent ductus arteriosus, ventricular septal defect and atrial septal defect were included in this prospective study. Clinical data were obtained before and after the catheterization. RESULTS: One hundred and thirty-eight patients were enrolled; and four (3%) patients developed intravascular hemolysis; while two cases had residual shunt and two other cases had not residual flow. Although residual shunt occurred in ten patients, only 2 of these cases developed hemolysis. Patent ductus arteriosus closure was done for one of these cases and the other one, underwent perimembranous ventricular septal defect closure. Moreover, hemolysis occurred after device closure of patent ductus arteriosus in 2 of the other patients with no residual shunt. In this study the hemolysis was eliminated by conservative management within 2 weeks although residual shunt continued in this time. We observed a decline in lactate dehydrogenase value after catheterization in comparison with precatheterization, which was mainly among ventricular septal defect patients that might be due to mild chronic hemolysis in these patients. CONCLUSION: Incidence of hemolysis after device closure was low, and occurred with and without residual flow and was eliminated by conservative management in 2 weeks, without the need for surgery, although the residual shunt was continued.

Echocardiography-guided percutaneous closure of perimembranous ventricular septal defects without arterial access and fluoroscopy.

BACKGROUND: Traditional percutaneous device closure of perimembranous ventricular septal defects (PmVSDs) is a minimally invasive technique, but can result in high radiation exposure and can result in potential arterial complications. Here, we aimed to assess the safety and feasibility of device closure of PmVSDs via the femoral vein approach under transesophageal echocardiography (TEE) guidance in children. METHODS: From January 2014 to December 2017, a total of 46 PmVSD patients (mean age, 6.5 ± 2.3 years [range, 4.2-12.0 years]; mean body weight 22.1 ± 6.6 kg [range, 16.0-38.5 kg]; VSD diameter, 4.1 ± 0.6 mm [range, 3.2-5.0 mm]) underwent attempted transcatheter closure via the femoral vein approach under the guidance of TEE without fluoroscopy. RESULTS: The transcatheter occlusion procedure under TEE guidance was successful in 44 (95.7%) patients. Surgery was necessary in 2 (4.3%) patients. The procedure duration was 28.2 ± 8.7 min (range, 12.0-42.0 min). One patient had immediate post-operative trivial residual shunt and three patients had immediate incomplete right bundle branch block (IRBBB) after operation; the new IRBBB in 1 case was noted in the first postoperative month. No residual shunt was noted at 3 months after the procedure, and no intervention related complications were detected at 1-24 months follow-up. CONCLUSIONS: Percutaneous device closure of PmVSDs under TEE guidance solely by femoral vein approach is effective and safe, avoids radiation exposure, potential arterial complications and a surgical incision.

Hybrid approach to ventricular septal defect enlargement.

The need for creation or enlargement of a ventricular septal defect (VSD) is a rare occurrence. It is most frequently required in patients with double-outlet right ventricle who develop restriction of a remote muscular VSD or obstruction of a perimembranous VSD secondary to atrioventricular (AV) valve attachments to the interventricular septum. Surgical and transcatheter options for VSD creation or enlargement are associated with several risks including heart block, AV valve injury, and perforation. We report the first description of a hybrid approach to VSD creation and enlargement in two patients.

Comparison of Fast-Track and Conventional Anesthesia for Transthoracic Closure of Ventricular Septal Defects in Pediatric Patients.

BACKGROUND: To compare and analyze the safety and efficacy of fast-track and conventional anesthesia for transthoracic closure of ventricular septal defects (VSDs) in pediatric patients. METHODS: A total of 82 pediatric patients undergoing transthoracic closure of VSDs between September and December 2017 were retrospectively analyzed. The patients were divided into two groups, including 42 patients in group F (fast-track anesthesia) and 40 patients in group C (conventional anesthesia). The perioperative clinical data of both groups were collected and statistically analyzed. RESULTS: There were no fatal complications in both groups. No complete atrioventricular block (AVB), new aortic valve regurgitation, and device closure failure were observed. No significant difference was found in preoperative general data or intraoperative hemodynamic changes between the two groups (P >0.05). However, the mechanical ventilation time, length of postoperative intensive care unit (ICU) stay, length of hospital stay, and hospitalization expenses of group F were significantly lower than those of group C (P <0.05). CONCLUSION: It is safe and effective to use fast-track anesthesia for transthoracic closure of VSDs in pediatric patients.

Preoperative Extracorporeal Membrane Oxygenation for Postinfarction Ventricular Septal Defect.

The mortality rate after the development of ventricular septal defect (VSD) remains high despite progress in pharmaceutical therapy, invasive cardiology, and surgical techniques. Although early surgical repair of postinfarction VSD is associated with a high mortality rate, in hemodynamic unstable patients surgery cannot always be postponed and surgical repair may be required urgently. We present two cases of patients diagnosed with postinfarction VSD who were in cardiogenic shock with multiorgan failure despite optimal treatment. They were therefore connected to venoarterial extracorporeal membrane oxygenation as a bridge to reparative surgery.

Trends in surgical and catheter interventions for isolated congenital shunt lesions in the UK and Ireland.

OBJECTIVE: To evaluate time trends in the use of catheter and surgical procedures, and associated survival in isolated congenital shunt lesions. METHODS: Nationwide, retrospective observational study of the UK National Congenital Heart Disease Audit database from 2000 to 2016. Patients undergoing surgical or catheter procedures for atrial septal defect (including sinus venosus defect), patent foramen ovale, ventricular septal defect and patent arterial duct were included. Temporal changes in the frequency of procedures, and survival at 30 days and 1 year were determined. RESULTS: 40 911 procedures were performed, 16 604 surgical operations and 24 307 catheter-based interventions. Transcatheter procedures increased over time, overtaking surgical repair in 2003-2004, while the number of operations remained stable. Trends in interventions differed according to defect type and patient age. Catheter closure of atrial septal defects is now more common in children and adults, although surgical interventions have also increased. Patent foramen ovale closure in adults peaked in 2009-2010 before falling significantly since. Surgery remains the mainstay for ventricular septal defect in infants and children. Duct ligation is most common in neonates and infants, while transcatheter intervention is predominant in older children. Excluding duct ligation, survival following surgery was 99.4% and ≈98.7%, and following catheter interventions was 99.7% and ≈99.2%, at 30 days and 1 year, respectively. CONCLUSIONS: Trends in catheter and surgical techniques for isolated congenital shunt lesions plot the evolution of the specialty over the last 16 years, reflecting changes in clinical guidelines, technology, expertise and reimbursement, with distinct patterns according to lesion and patient age.

Management of post-myocardial infarction ventricular septal defects: A critical assessment.

BACKGROUND: Post-myocardial infarction (MI) ventricular septal defects (PIVSD) are an uncommon but life-threatening complication of acute MI. Although surgical closure has been the standard of care, mortality, and recurrence of VSD remain high even after emergent surgery. Transcatheter VSD closure (TCC) devices have become an alternative or adjunct to surgical closure. METHODS: Online database search was performed for studies that included adults with PIVSD who underwent medical treatment (MT) alone, surgical closure (SC) (early or late), and TCC (early, late, or for post-surgical residual VSD). RESULTS: Twenty-six studies were included with a total of 737 patients who underwent either MT (N = 100), SC (early (n = 167), late (n = 100)), and TCC (early (n = 176), late (n = 115), or post-surgical residual VSD (n = 79)). The 30-day mortality among MT group was 92 ± 6.3%, among SC was 61 ± 22.5% (early 56 ± 23%, late 41 ± 30%), and for all TCC patients was 33 ± 24% (early 54 ± 32.7%, late 16 ± 26%), and TCC for post-surgical residual VSD 11 ± 34.9%. The mortality among overall SC, overall TCC and early TCC groups was significantly lower as compared with the MT (P < 0.001 for all comparisons). The overall mortality among all TCC, and late TCC groups was significantly lower when compared with the late SC (P < 0.0001, P < 0.0001, respectively). CONCLUSION: Closure of PIVSD decreases mortality as compared with MT alone and should be attempted as early as possible after diagnosis. Selection of TCC versus SC should be based on factors including complexity of the defect, availability of closure devices, expertise of the operator, and clinical condition of patient.

The Comparison of Perventricular Device Closure with Transcatheter Device Closure and the Surgical Repair via Median Sternotomy for Perimembranous Ventricular Septal Defect.

BACKGROUND: Perventricular and transcatheter device closures are performed for perimembranous ventricular septal defect (pmVSD) to reduce the surgical trauma of conventional surgical repair via median sternotomy. Few comparative studies have been conducted among these three procedures. METHODS: From June 2015 to May 2016, 247 patients with isolated pmVSD who had undergone perventricular or transcatheter device closure or conventional surgical repair were reviewed to compare these three procedures. RESULTS: The procedure success rate was similar in these three groups. There were a statistically significant difference in operative time, aortic cross-clamping time, duration of cardiopulmonary bypass (CPB), blood transfusion amount, and medical cost in these three groups. Meanwhile, postoperative mechanical ventilation time, duration of intensive care, and length of hospital stay were longer in surgical group than the other two groups. The surgical group required the longest incision. No significant difference was noted in major adverse events. There were different advantages and disadvantages in these three kinds of procedures. CONCLUSIONS: Device closure may be alternative to conventional surgical repair for patients with isolated pmVSD. Perventricular device closure was the preferred procedure because it showed more maneuverable than transcatheter procedure with the same clinical result.

Waiting for Cardiac Procedure in Congenital Heart Disease: Portrait of an a Hospital in the Amazonian Region / Fila de Espera para Tratamento de Pacientes com Cardiopatia Congênita: Retrato de um Centro de Referência Amazônico

Congenital heart disease is an important cause of morbidity and mortality in childhood, and in 50% of cases, surgery is required in the first year of life. A high deficit of surgical procedures is estimated in Northern Brazil. Objective: To analyze the waiting time for elective surgical treatment and/ or intervention in children with congenital heart disease in a Cardiology referral center, and to make considerations about heart diseases and forms of treatment in that institution. Methods: A cross-sectional study of all patients aged less than 14 years, with a diagnosis of congenital heart disease that were waiting for elective surgical or percutaneous cardiac treatment. Results: Among the 407 children with congenital heart defects, the most prevalent age group was > 2 to 6 years (34.0%). The average waiting time was 23.1 ± 18.3 months, with a median of 19. The most frequent heart disease was ventricular septal defect (28.98%), patent ductus arteriosus (18.42%) and atrial septal defect (11.05%). Most children (63.4%) were not from the metropolitan area. The percutaneous interventions represented only 27.84% of the catheterization procedures and 14,85% of all heart treatments. Approximately 60% of the pediatric surgeries occurred in children who were not previously registered due to urgency cases. Conclusion: Most of the children waiting for a cardiac procedure were not from the metropolitan area and had malformations potentially treatable by catheterization. It is necessary to increase the capacity of the single referral center in the state of Pará, as well as decentralize the high-complexity cardiological care in the metropolitan region

As cardiopatias congênitas são importantes causas de morbimortalidade infantil e, em cerca de 50% dos casos, é necessária a intervenção cirúrgica no primeiro ano de vida. Estima-se alto défice de procedimentos na Região Norte do Brasil. Objetivo: Analisar o tempo de espera para realização de tratamento eletivo cirúrgico e/ou intervencionista de crianças portadoras de cardiopatias congênitas em um centro de referência cardiológico, e fazer considerações sobre as cardiopatias e suas formas de tratamento na referida instituição. Método: Estudo analítico, de caráter transversal do período de janeiro de 2012 a outubro de 2014, de pacientes com idade igual ou inferior a 14 anos diagnosticados com cardiopatias congênitas que estavam na fila de tratamento cardíaco eletivo cirúrgico ou percutâneo. Resultados: Das 407 crianças que aguardavam por tratamento, a faixa etária mais prevalente foi a de > 2 a 6 anos (34,0%). O tempo médio de espera, em meses, foi 23,1 ± 18,3, com mediana de 19. As cardiopatias mais frequentes foram comunicação interventricular (28,98%), persistência do canal arterial (18,42%) e comunicação interatrial (11,05%). A maioria das crianças (63,4%) não pertencia à região metropolitana. As intervenções percutâneas representaram somente 27,84% do total de cateterismos e 14,85% de todos os tratamentos cardíacos. Cerca de 60% do volume de cirurgias pediátricas ocorreu em crianças sem cadastro prévio no sistema, devido ao caráter de urgência. Conclusão: Grande parte das crianças que aguardam por procedimento cardíaco é procedente de fora da região metropolitana e tem malformações potencialmente tratáveis por cateterismo. É necessário aumentar a capacidade operacional do único centro de referência público do Estado, além de descentralizar o atendimento em alta complexidade cardiológica da região metropolitana

Relato de caso sobre comunicação interventricular pós-infarto agudo do miocárdio / Case report on acute postinfarction myocardial interventricular septal rupture

O presente artigo relata dois casos de pacientes, os quais foram admitidos na emergência do Instituto de Moléstias Cardiovasculares (IMC) com dor tipicamente anginosa, caracterizada como dor retroesternal em aperto, com irradiação para a face medial do braço esquerdo e relacionada ao esforço, com melhora no repouso. No exame físico, apresentavam taquicardia e sudorese. O eletrocardiograma evidenciou sinais de isquemia miocárdica em ambos os pacientes. Após as medidas iniciais serem tomadas, um dos pacientes foi submetido à terapia trombolítica e o outro à angioplastia para implantação de stent . Mais tarde, foi identificada a comunicação interventricular (CIV), seguido da necessidade de correção cirúrgica da mesma. Ambos os pacientes evoluíram bem, apesar da alta taxa de mortalidade desta condição

This paper reports two cases of patients who were admitted to the emergency room of the Instituto de Moléstias Cardiovasculares (IMC) with typically anginal pain, characterized by tight retrosternal pain radiating to the inside left arm, related to stress and improving with rest. Physical examination showed tachycardia and excessive sweating. Electrocardiogram showed signs of myocardial ischemia in both patients. After the initial measures were taken, one of the patients received thrombolytic therapy, and the other angioplasty for stent implantation. Later, interventricular septum rupture (IVSR) was identified, followed by the need for surgery to correct it. Both patients recovered well, despite the high mortality rate of this condition

Prolonged prostaglandin-E2-associated periosteal reaction and elevated C-reactive protein levels.

This is a case review of two infants who received a prolonged course of prostaglandin-E2 therapy for congenital cardiac lesions while awaiting corrective surgery. These cases highlight an association between prolonged prostaglandin-E2 therapy with periosteal reactions and elevated C-reactive protein levels. Failure to recognise this association may lead to multiple courses of antibiotics for presumed sepsis and further prolongation of prostaglandin-E2 therapy.
