Better Late Than Never: Definitive Anatomic Repair of Dextro-Transposition of the Great Arteries. JACC Case Rep 2024; 29:102269. [PMID: 38645291 PMCID: PMC11031650 DOI: 10.1016/j.jaccas.2024.102269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 12/18/2023] [Accepted: 01/16/2024] [Indexed: 04/23/2024]
Abstract
We present a case of anatomic repair of dextro-transposition of the great arteries (d-TGA) with ventricular septal defect (VSD) in a 55-year-old man who presented with acute heart failure. This case highlights the importance of multimodal imaging and multidisciplinary involvement in developing a comprehensive surgical and medical plan for adults with congenital heart disease. We think this is the oldest reported patient undergoing anatomic surgical repair of d-TGA with VSD.

Innovative ultrasound-guided one-stop surgery for complex cardiovascular cases: a case report. J Surg Case Rep 2024; 2024:rjad696. [PMID: 38186756 PMCID: PMC10766588 DOI: 10.1093/jscr/rjad696] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2022] [Accepted: 12/05/2023] [Indexed: 01/09/2024] Open
Abstract
Elderly patients with multiple comorbidities often face complex cardiac challenges, including aortic valve issues and atrial septal defects. Traditional open-heart surgery may not be viable for this demographic. Transcatheter aortic valve implantation (TAVI) emerges as a preferred alternative. In this case, a frail patient with multiple comorbidities, atrial septal defect, and significant aortic stenosis and regurgitation underwent a one-stop procedure, combining TAVI and atrial septal defect closure, guided by advanced imaging, including three-dimensional ultrasound. Ultrasound played a pivotal role in the perioperative phase, offering precise screening and guidance. This innovative technique, minimizing surgical trauma and recovery time, significantly improved the patient's quality of life.

Results and Complications After Single-Stage Repair of Aortopulmonary Window and Interrupted Aortic Arch in a 32-Week Preterm and a Full-Term Neonate. AMERICAN JOURNAL OF CASE REPORTS 2023; 24:e942193. [PMID: 38124359 PMCID: PMC10750801 DOI: 10.12659/ajcr.942193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 11/21/2023] [Accepted: 11/11/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND An aortopulmonary window (APW) is an uncommon congenital defect of the septation between the ascending aorta and pulmonary trunk. The combination of APW and interrupted aortic arch (IAA) is even rarer, with the hallmark characteristics of high peri-operative mortality and postoperative obstruction of the aortic arch, pulmonary artery, and left main bronchus. These complications often need re-interventions. CASE REPORT We present 2 cases with diagnoses of APW and IAA that were treated with single-stage repair. Case 1: A male 32-week premature newborn (weight 1789 g) had APW type I and IAA type A. He had severe postoperative aortic arch obstruction on postoperative day 1, and we re-intervened promptly. He was still asymptomatic after 6 years. Case 2: A male term neonate had APW type III and IAA type A. He had left vocal cord paralysis and left bronchial compression postoperatively. We applied prolonged noninvasive respiratory supports. The complications resolved without re-intervention on postoperative day 66. Progressive arch stenosis at anastomosis after operation required close follow-up with echocardiography. CONCLUSIONS These 2 reports highlight the feasibility of single-stage surgical repair while addressing 2 challenges: (1) Recurrent arch stenosis: Lower body weight and direct end-to-side anastomosis without patch augmentation could be risk factors for re-intervention. (2) Bronchial compression: Presentation of the second reported case implied that bronchial compression may not warrant immediate re-intervention unless there is complete obstruction, persistent atelectasis, or recurrent infection. Further studies on long-term outcomes of different surgical procedure would help us to clarify the proper way to avoid re-intervention.

Abstract
This case report presents a detailed exploration of an adult-onset 22q11 deletion syndrome, a rare genetic disorder typically diagnosed in children. The report highlights the diagnostic challenges posed by this atypical presentation, emphasizing the need for clinicians to consider such conditions in differential diagnoses, especially in adults. This case is remarkable for its late onset and mild symptoms, which significantly deviated from the common pediatric presentation, including hypocalcemia due to hypoparathyroidism and a fenestrated atrial septal defect without significant hemodynamic implications. The importance of recognizing the broad phenotypic variability of the syndrome and the implications for clinical practice are discussed, providing insights into the genetic and phenotypic diversity of the condition. In conclusion, this case illuminates the diverse clinical spectrum of adult-onset 22q11 deletion syndrome, emphasizing its relevance to clinical practice.

Complete Transthoracic Echocardiography for the Assessment and Guidance of Percutaneous Atrial Septal Defect Closure in Adults without Balloon Sizing: An Observed Study with a 10-Year Follow-Up. J Cardiovasc Dev Dis 2023; 10:321. [PMID: 37623334 PMCID: PMC10455240 DOI: 10.3390/jcdd10080321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 07/25/2023] [Accepted: 07/26/2023] [Indexed: 08/26/2023] Open
Abstract
OBJECTIVES This study aims to determine if complete transthoracic echocardiography (TTE)-guided percutaneous atrial septal defect (ASD) closure without balloon sizing could be safe and efficacious in adult patients. METHODS A total of 551 patients with ASDs were enrolled in this study, of which 438 patients underwent percutaneous ASD closure. Patients who received TTE-guided percutaneous ASD closure were classified into group T, and those who underwent a procedure that was guided by transesophageal echocardiography (TEE) were classified into group E. The clinical characteristics and the outcomes of the patients were analyzed. RESULTS The characteristics were comparable at baseline, except for the body mass index (BMI) (21.6 ± 5.3 vs. 23.8 ± 7.1, p < 0.001) between group T and group E. No significant difference was observed between the two groups regarding in-hospital outcomes, except for the duration of the procedure (29.8 ± 15.3 min vs. 41.5 ± 20.4 min), the length of stay in the hospital (2.1 ± 2.3 d vs. 2.9 ± 2.6 d), and hospital costs (USD 6233.3 ± 312.4 vs. USD 6673.7 ± 446.9). There were no significant differences in the incidences of long-term complications, cardiac chamber sizes, and tricuspid regurgitation severity between the patients in the two groups during the 10-year follow-up period. CONCLUSION TTE may be as safe and efficacious as TEE for the assessment and guidance of percutaneous ASD closure without balloon sizing in adult patients with lower BMIs who are commonly found in East Asia.

Abstract
BACKGROUND Pulmonary hypertension (PH), recently redefined as mean pulmonary arterial pressure >20 mm Hg (PH20), may be observed in patients with atrial septal defects (ASD). We aimed to determine the effect of preprocedural PH20 status on outcomes among patients undergoing ASD closure. METHODS Study population was selected from a retrospective registry of adult patients who underwent percutaneous ASD closure from 1998 to 2016 from a single center and had right heart catheterizations during the procedure. The clinical registry was linked to administrative databases to capture short- and long-term outcomes. RESULTS We included a total of 632 ASD closure patients of whom 359 (56.8%) had PH20. The mean follow-up length was 7.6±4.6 years. Patients with PH20 were older (mean age 56.5 versus 43.1 years, P<0.001) and a higher prevalence of comorbidities including hypertension (54.3% versus 21.6%, P<0.001) and diabetes (18.1% versus 5.9%, P<0.001) than those without PH. In a Cox proportional hazards model after covariate adjustment, patients with PH had a significantly higher risk of developing major adverse cardiac and cerebrovascular events (heart failure, stroke, myocardial infarction, or cardiovascular mortality), with hazards ratio 2.45 (95% CI, 1.4-4.4). When applying the prior, mean pulmonary arterial pressure ≥25 mm Hg (PH25) cutoff, a significantly higher hazard of developing major adverse cardiac and cerebrovascular events was observed in PH versus non-PH patients. CONCLUSIONS ASD patients with PH undergoing closure suffer from more comorbidities and worse long-term major adverse cardiac and cerebrovascular events outcomes, compared with patients without PH. The use of the new PH20 definition potentially dilutes the effect of this serious condition on outcomes in this population.

Abstract
OBJECTIVE The ostium secundum atrial septal defect (ASD) is among the most common congenital cardiac anomalies diagnosed in adulthood. A known complication of transcatheter ASD closure is the development of new-onset atrial fibrillation and flutter (AFi/AFl). These arrhythmias confer an increased risk of postoperative stroke, thrombus formation and systemic emboli. This systematic review examines the burden of de novo AFi/AFl in adults following transcatheter closure and seeks to identify risk factors for AFi/AFl development. METHODS Studies were identified by a search of MEDLINE, EMBASE and Cochrane databases from inception until 29 April 2020. A meta-analysis of AFi/AFl incidence was performed using a random-effects model. RESULTS A total of 31 studies met inclusion criteria, comprising 4788 adult patients without a history of AFi/AFl. Twenty-three studies were included in quantitative synthesis and demonstrated an overall incidence rate of 1.82 patients per 100 person-years of follow-up (I2=83%). In studies that enrolled only patients ≥60 years old, the incidence was 5.21 patients per 100 person-years (I2=0%). Studies with follow-up duration ≤2 years reported an incidence of 4.05 per 100 person-years (I2=55%) compared with a rate of 1.19 per 100 person-years (I2=85%) for studies with follow-up duration >2 years. CONCLUSIONS The incidence of new-onset AFi/AFl is relatively low following transcatheter closure of secundum ASDs. The rate of de novo AFi/AFl, however, was significantly higher in elderly patients. Shorter follow-up time was associated with a higher reported incidence of AFi/AFl.

Abstract
Cardiac involvement in familial amyloid polyneuropathy consists of arrhythmias, conduction disturbances, and heart failure. To our knowledge, heart rupture has never been described in association with this condition. We report the case of a 62-year-old man with a 6-year history of refractory familial amyloid polyneuropathy who underwent liver transplantation. The operation was complicated by severe hypotension because the neuropathy involved the autonomic system. Perioperatively, the patient had a myocardial infarction, and during the next 10 days, a complete interventricular septal rupture developed, resulting in a systemic-to-pulmonary shunt. Coronary angiographic findings were normal. However, the shunt caused unstable hemodynamics, resulting in cardiogenic shock. An attempt to close the rupture percutaneously failed. The patient underwent successful heart transplantation 50 days later. Macroscopic examination of the explanted heart showed thickening of both ventricles, septal rupture, and a gray scar in the interventricular septum around the cavity. Histopathologic examination revealed intramural amyloid angiopathy. Our case shows that heart rupture can occur in patients with familial amyloid polyneuropathy who have no history of obstructive coronary artery disease, perhaps as a result of tissue fragility caused by amyloid angiopathy. Therefore, autonomic disturbances should be regarded with concern and promptly treated in the perioperative period.

Abstract
OBJECTIVES We sought to clarify the variations in the anatomy of the superior cavoatrial junction and anomalously connected pulmonary veins in patients with superior sinus venosus defects using computed tomographic (CT) angiography. METHODS CT angiograms of 96 consecutive patients known to have superior sinus venosus defects were analysed. RESULTS The median age of the patients was 34.5 years. In seven (7%) patients, the defect showed significant caudal extension, having a supero-inferior dimension greater than 25 mm. All patients had anomalous connection of the right superior pulmonary vein. The right middle and right inferior pulmonary vein were also connected anomalously in 88 (92%) and 17 (18%) patients, respectively. Anomalous connection of the right inferior pulmonary vein was more common in those with significant caudal extension of the defect (57% vs 15%, p=0.005). Among anomalously connected pulmonary veins, the right superior, middle, and inferior pulmonary veins were committed to the left atrium in 6, 17, and 11 patients, respectively. The superior caval vein over-rode the interatrial septum in 67 (70%) patients, with greater than 50% over-ride in 3 patients. CONCLUSION Anomalous connection of the right-sided pulmonary veins is universal, but is not limited to the right upper lobe. Not all individuals have over-riding of superior caval vein. In a minority of patients, the defect has significant caudal extension, and anomalously connected pulmonary veins are committed to the left atrium. These findings have significant clinical and therapeutic implications.

Abstract
Over the past few decades, advances in pharmacological, catheter-based, and surgical reperfusion have improved outcomes for patients with acute myocardial infarctions. However, patients with large infarcts or those who do not receive timely revascularization remain at risk for mechanical complications of acute myocardial infarction. The most commonly encountered mechanical complications are acute mitral regurgitation secondary to papillary muscle rupture, ventricular septal defect, pseudoaneurysm, and free wall rupture; each complication is associated with a significant risk of morbidity, mortality, and hospital resource utilization. The care for patients with mechanical complications is complex and requires a multidisciplinary collaboration for prompt recognition, diagnosis, hemodynamic stabilization, and decision support to assist patients and families in the selection of definitive therapies or palliation. However, because of the relatively small number of high-quality studies that exist to guide clinical practice, there is significant variability in care that mainly depends on local expertise and available resources.

Abstract
AIMS Congenital heart disease is among the most common congenital anomalies in pediatrics. The aim of this study was to evaluate the prevalence of congenital heart disease in children in Khorramabad, Iran. METHODS This is a descriptive-cross sectional study where all the children diagnosed with congenital heart disease by echocardiography were enrolled to the Shahid Madani Hospital. Patient information was collected by means of a questionnaire. Of 1600 children who underwent cardiac counseling, 9.75% presented congenital heart disease. These were most prevalent among the children of 0-28 days of the age (14.7%) and least in children aged 1 month-1 year. According to this study, atrial (20.3%) and ventricular septal defect (10.5%) were the most common heart defects, respectively. Among signs and symptoms of cardiac disease, 49.1% of children had cyanosis, 89.7% with increased CT (cardiothoracic)-ratio, and 82.7% of had heart murmur. Congenital heart disease was more prevalent in male infants (58%) and 6.6% patients had heart failure and 1.4% had other congenital conditions, such as Down syndrome. RESULTS According to our findings, atrial and ventricular septal defects are the most common congenital heart anomalies, respectively, in pediatric patients in Khorramabad.

Abstract
A 7-year-old boy with a history of neonatal pulmonary artery banding underwent almost complete closure of a sieve-like "Swiss-cheese" ventricular septal defect, using a combination sandwich patch technique through a right ventriculotomy. Although defects existed in the high-, mid-, and low-trabecular septa, a right ventriculotomy and division of the muscle trabeculations continuing the septal and moderator bands helped delineate the edges of the defects. Although patients with "Swiss-cheese" ventricular septal defects may be candidates for a Fontan operation conventionally, a combination patch technique could be considered the procedure of choice.

Abstract
Tetralogy of Fallot (ToF) is considered the most frequent cyanotic congenital heart abnormality with a low adulthood survival rate if kept untreated. The majority of cases are symptomatic during infancy and mandate early treatment. Few instances of survival to asymptomatic middle-age patients have been reported, and they are decreasing due to early detection. We reported a case of a middle-aged man who was asymptomatic during his life and recently diagnosed with ToF. The patient underwent surgical repair with excellent outcomes. The case represents the possibility of diagnosing such cases in a relatively old patient despite medical development and advances.

Abstract
Coronary artery anomalies are a diverse group of disorders with highly variable manifestations and pathophysiological mechanisms. The origin of a single coronary artery from an atretic pulmonary trunk is a rare anomaly. We encountered this in an 8-day-old female newborn. This report should alert the cardiac surgical community to this fatal coronary malformation. Surgeons should bear this anomaly in mind when they face unusual myocardial behavior intraoperatively.

Abstract
Iatrogenic atrial septal defect is an issue after percutaneous interventions for structural heart disease. A 63-year-old man, who had previously received 5 catheter ablations for paroxysmal atrial fibrillation, was found to have an iatrogenic atrial septal defect that persisted after the fourth intervention. Approximately 4 years later, he suffered exertional dyspnea. Pulmonary hypertension was caused by a left-to-right shunt via a large iatrogenic atrial septal defect. We performed surgical closure and the symptom improved. The timing of treatment for persistent iatrogenic atrial septal defect is difficult to determine, but preferable before the appearance of right ventricular dysfunction or embolism.

Abstract
The introduction of the arterial switch operation has improved the surgical outcome of transposition of the great arteries. However, coronary anomalies such as intramural coronary arteries, single coronary artery, or coronary arteries originating from a single arterial sinus have been reported as independent risk factors for early mortality and late morbidity after an arterial switch operation. We performed an arterial switch operation using a unique technique for translocation of the coronary arteries originating from a single left-side arterial sinus, to prevent coronary artery distortion and subsequent coronary malperfusion.

Abstract
Background Ventricular septal defect, the most common congenital heart defect, is characterized by an opening between the ventricles. This study aimed to evaluate the clinical course and associations between the characteristics of ventricular septal defect. Methods This cross-sectional study was conducted on 1498 children with ventricular septal defects, aged <19 years, who were referred to our center between 2003 and 2018. The diagnosis was suspected from a combination of clinical and laboratory findings, and confirmed by transthoracic echocardiography. Results Of the 1498 children, 54.9% were boys, 78.4% of defects were perimembranous, 30.4% of patients had pulmonary hypertension, 67.5% had regular follow-up, and 76 (5.1%) had complications including 28 (1.9%) with Eisenmenger syndrome; 10 died due to Eisenmenger syndrome during follow-up. The defects closed spontaneously in 38.9% and after surgery in 20.9%. Boys tended to have more perimembranous, inlet, and outlet forms (56.40%, 50.60%, 51.90%, respectively), whereas girls had more muscular types (51.80%). Most patients with pulmonary hypertension had perimembranous defects (83.10%). The majority of patients with pulmonary hypertension had large (63.40%) or moderate (36.60%) defects. Pulmonary hypertension had a significant association with defect size ( p < 0.001). After surgery, residual defects were found mostly in cases of large defects (84.60%). Most patients with spontaneous closure were younger than 4 years. Conclusion Almost four-fifths of children with ventricular septal defects had perimembranous types, and almost one-third had pulmonary hypertension which was associated with defect size. Two-fifths of the defects closed spontaneously. There was a low incidence of complications after surgery.

Abstract
A child with Down syndrome, who had undergone uneventful ventricular septal defect repair one year earlier with a normal heart rate during routine follow-up, presented with recurrent seizure-like episodes that did not respond to antiepileptics. She was subsequently found to have complete heart block with significant bradycardia requiring permanent pacemaker insertion. This late and unusual presentation of complete heart block after ventricular septal defect repair is discussed. Prudence must be applied in the evaluation of children who have undergone surgical correction of congenital heart defects and presented with recurrent seizure-like episodes.

Abstract
BACKGROUND The magnitude of pulmonary hypertension (PH) is extremely important with respect to the intra-operative management of children and infants with an isolated ventricular septal defect (VSD). This study aimed to assess the feasibility and accuracy of transesophageal echocardiography for estimating pulmonary arterial systolic pressure (PASP) across isolated VSD. METHODS We compared the results of transesophageal echocardiography vs invasive PASP measured simultaneously. This study included 40 patients (age: 6 months to 6 years; weight: >5 kg) who were undergoing elective surgery for isolated VSDs. Flow signals across the VSDs were identified as high velocity turbulent signals in systole via continuous wave Doppler at 0-120° at the mid-esophageal level. Peak velocities were recorded. Radial artery systolic pressures were assessed invasively, and PASPs were obtained after exposing the pulmonary artery intra-operatively. RESULTS After excluding five patients because of unusable measurements, invasive PASP measurements were obtained in 35 patients (87.5%). There were no significant biases between echocardiographic and catheterization measurements of PASP, with a tight confidence interval measuring, on average, up to 2.6 mmHg. However, the ± 2 standard deviation limits of agreement for mean PASP were -3.8 and 10.6 mmHg. CONCLUSION PASP measurements via transesophageal echocardiography in cardiac surgical patients under general anesthesia are recommended for use as a screening and monitoring tool for PH in children and infants, but cannot be used as a diagnostic tool.

Abstract
Left coronary artery compression syndrome is characterized by compression of the left main coronary artery between the aorta and an enlarged main pulmonary artery. A 39-year-old woman presented with angina with dyspnea on exertion for two years. Detailed investigations revealed an atrial septal defect, valvular lesions, and severe pulmonary hypertension with left main coronary artery compression. Patch closure of the atrial septal defect, left coronary artery bypass, and valve repair was carried out. The patient recovered well and was asymptomatic on follow-up. The optimal management of such patients is yet to be clarified.

Abstract
A neonate was diagnosed with ventricular septal defect and aortic coarctation. Bilateral pulmonary artery banding was performed at 9 days of age (weight 1472 g). Because of ductal shock, emergency extracorporeal membrane oxygenation was initiated after surgery. Fine adjustment of the bilateral pulmonary artery banding sites using hemoclips was carried out to facilitate weaning from extracorporeal membrane oxygenation, and staged delayed sternal closure was achieved. Arch repair, ventricular septal defect closure, and tricuspid annuloplasty were undertaken when the patient was 4-months old (weight 1.8 kg). She was discharged at 11 months of age (3.0 kg).

Left ventricular rotation and torsion in neonates and infants younger than three months with symptomatic ventricular septal defect: Acute effects from open heart surgery. JOURNAL OF CLINICAL ULTRASOUND : JCU 2019; 47:88-94.

Abstract
PURPOSE We evaluated ventricular rotation, torsion, and strain changes in infants using preoperative and postoperative M-mode echocardiography after early surgery for symptomatic ventricular septal defects (VSD). METHODS Thirty-five patients with VSD underwent vector velocity imaging echocardiography before and after open heart surgery. Their rotational variables were compared with 18 controls. RESULTS All the patients (19 boys and 16 girls; median age: 44.4 days; range: 13-84 days) showed normal septal motion preoperatively; however, septal motion changed into flat septum or paradoxical septal motion after surgery. Left ventricular end-diastolic internal dimension and fractional shortening significantly decreased after surgery (P = .001 and P = .000). Patients showed significant postoperative reduction of peak systolic apical rotation and maximal torsion (P = .010 and P = .000). Peak systolic basal rotation decreased after surgery but it was not significantly (P = .106). No significant differences were found in longitudinal and circumferential systolic strains between patients and controls. CONCLUSION Abnormal motion of the ventricular septum was confirmed by postoperative M-mode echocardiography. Decreased rotation/torsion variables may reflect postoperative changes of ventricular loading conditions. Because systolic strain was preserved, postoperative echocardiographic results should not be interpreted as abnormal or decreased ventricular function.

Abstract
An 8-year-old girl with no history of chest pain or exertional dyspnea was admitted for atrial septal defect closure. Transthoracic echocardiography showed a sac in the right atrium, protruding from the left ventricle. A left ventricular aneurysm was confirmed by cardiac catheterization. At surgery, the protruding saccular aneurysm arising from the left ventricle was located between the atrial septal defect and the tricuspid valve. We closed the orifice with interrupted sutures from the right atrium. The atrial septal defect was closed with an autologous pericardial patch. Histology showed the aneurysmal wall had no myocardial layer, being replaced by fibrous tissue.

Atrial septal defect in adults is associated with airway hyperresponsiveness. CONGENIT HEART DIS 2018; 13:959-966.

Abstract
OBJECTIVE The association between secundum atrial septal defects (ASD) and asthma-like dyspnea with consequent long-term pulmonary inhalant use, is poorly understood in adult ASD patients. Airway hyperresponsiveness is suggested to be the underlying mechanism of cardiac asthma from mitral valve disease and ischemic cardiomyopathy. We hypothesized that airway hyperresponsiveness may also be found in adult ASD patients. Our aim was to study airway responsiveness in adult ASD patients before percutaneous closure and at short-and long-term postprocedural follow-up. METHODS This prospective study included 31 ASD patients (65% female, mean age 49 ± 15y) who underwent spirometry and bronchoprovocation testing pre-and six-month postprocedurally, with additional bronchoprovocation at 2-year follow-up. Airway hyperresponsiveness was defined as ≥20% fall of forced expiratory volume in 1-second (FEV1 ) following <8.0 mg/mL of inhaled methacholine. RESULTS Airway hyperresponsiveness was found in 19/30 patients (63%[95%CI 45%-81%]; post hoc statistical power = 89%). Asthma-like symptoms wheezing, chest tightness, and cough were more frequently reported in airway hyperresponsive patients. Airway responsiveness was not influenced by successful percutaneous ASD closure, corresponding to persistence of asthma-like symptoms postclosure. Regardless of airway responsiveness, postprocedural right-sided reverse remodeling significantly improved dyspnea and pulmonary function. CONCLUSIONS This study is the first to report a high prevalence of airway hyperresponsiveness in a cohort of unrepaired adult ASD patients, and confirms the association between asthma-like symptoms and ASD in adults. Attention to symptoms and pulmonary function should be given during clinical follow-up of adult ASD patients, both before and long after repair.

Abstract
Air embolism is a rare but mostly iatrogenic complication of medical or surgical procedures and may have a serious outcome. On the removal of a central venous catheter (CVC), minor carelessness can lead to a venous air embolism sometimes accompanied by arterial embolism. We experienced the case of a 61-year-old male who suffered from a paradoxical systemic air embolism while we removed a CVC. Immediate resuscitation and venovenous extracorporeal membrane oxygenation support saved his life. Multiple end-organ damage related to the systemic air embolism was noted, including the kidney, liver, and brain. In echocardiography, multiple air bubbles and an atrial septal defect were observed. An air embolism is preventable with appropriate precautions and techniques. Therefore, it is important to identify errors and prevent occurrence.

Abstract
Background— Prospective data on the medium-term safety and effectiveness of the AMPLATZER Septal Occluder in clinical practice are not available. The objective of this study was to prospectively evaluate the risk of hemodynamic compromise and obtain medium-term survival data on patients implanted with the AMPLATZER Septal Occluder for percutaneous closure of secundum atrial septal defects. Methods and Results— Subjects were enrolled prospectively at 50 US sites and followed for 2 years. Between 2008 and 2012, atrial septal defect closure with the AMPLATZER Septal Occluder was attempted in 1000 patients (aged 0.3–83.6 years, mean 21±22 years). Procedural closure occurred in 97.9%, with 1-month and 2-year closure 98.5% and 97.9%, respectively. Hemodynamic compromise occurred in 6 subjects (0.65%), because of dysrhythmia in 2, device embolization in 1, and cardiac erosion in 3. The rate of cardiac erosion was 0.3% (average 83, range 12–171 days from implant). Conclusions— Closure of atrial septal defect with the AMPLATZER Septal Occluder is safe and effective. The rate of hemodynamic compromise and cardiac erosion is rare. The risk factors for cardiac erosion after device closure are not yet clear.

Abstract
Ventricular septal defect (VSD) is a lethal complication of myocardial infarction. The event occurs 2-8 days after an infarction and patients should undergo emergency surgical treatment. We report on successful device closure of post-infarction VSD. A previously healthy 66-year-old male was admitted with aggravated dyspnea. Echocardiography showed moderate left ventricular (LV) systolic dysfunction with akinesia of the left anterior descending (LAD) territory and muscular VSD size approximately 2 cm. Coronary angiography showed mid-LAD total occlusion without collaterals. Without percutaneous coronary intervention due to time delay, VSD repair was performed. However, a murmur was heard again and pulmonary edema was not controlled 3 days after the operation. Echocardiography showed remnant VSD, and medical treatment failed. Percutaneous treatment using a septal occluder device was decided on. After the procedure, heart failure was controlled and the patient was discharged without complications. This is the first report on device closure of post-infarction VSD in Korea.

Abstract
BACKGROUND Intramural ventricular septal defects (VSDs) are interventricular communications through right ventricular free wall trabeculations that can occur after repair of conotruncal anomalies. We assessed the prevalence of residual intramural VSDs and their effect on postoperative course. METHODS AND RESULTS Children who underwent biventricular repair of a conotruncal anomaly from January 1, 2006, to June 30, 2013, and had a postoperative transthoracic echocardiogram were included. Images were reviewed for residual intramural or nonintramural VSDs. The primary outcome was a composite of mortality, extracorporeal membrane oxygenation use, and need for subsequent catheter or surgical VSD closure. The secondary outcome was postoperative hospital length of stay. A residual VSD was present in 256 of the 442 subjects (58%), of which 231 (90%) were <2 mm in size. Forty-nine patients (11%) had intramural VSDs, and 207 (47%) had nonintramural VSDs. Patients with intramural VSDs were more likely to reach the primary composite outcome compared with those with nonintramural VSDs or no residual VSD (14 of 49 [29%] versus 15 of 207 [7%] versus 6 of 186 [3%]; P<0.0001). In addition, those with intramural VSDs had longer postoperative hospital length of stay compared with those with nonintramural VSDs or no residual VSD (20 days [interquartile range, 11-42 days] versus 7 days [interquartile range, 5-14 days] versus 6 days [interquartile range, 4-11 days]; P=0.0001). These associations remained significant after adjustment for known risk factors for poor outcomes, including residual VSD size and operative complexity. CONCLUSIONS Among residual VSDs after repair of conotruncal anomalies, intramural VSDs are uniquely associated with postoperative morbidity, mortality, and longer postoperative hospital length of stay. It is important to recognize intramural VSDs in the postoperative period.

Abstract
BACKGROUND Defects in cardiac septation are the most common form of congenital heart disease, but the mechanisms underlying these defects are still poorly understood. The small GTPase Rac1 is implicated in planar cell polarity of epithelial cells in Drosophila; however, its role in mammalian cardiomyocyte polarity is not clear. We tested the hypothesis that Rac1 signaling in the second heart field regulates cardiomyocyte polarity, chamber septation, and right ventricle development during embryonic heart development. METHODS AND RESULTS Mice with second heart field-specific deficiency of Rac1 (Rac1(SHF)) exhibited ventricular and atrial septal defects, a thinner right ventricle myocardium, and a bifid cardiac apex. Fate-mapping analysis showed that second heart field contribution to the interventricular septum and right ventricle was deficient in Rac1(SHF) hearts. Notably, cardiomyocytes had a spherical shape with disrupted F-actin filaments in Rac1(SHF) compared with elongated and well-aligned cardiomyocytes in littermate controls. Expression of Scrib, a core protein in planar cell polarity, was lost in Rac1(SHF) hearts with decreased expression of WAVE and Arp2/3, leading to decreased migratory ability. In addition, Rac1-deficient neonatal cardiomyocytes displayed defects in cell projections, lamellipodia formation, and cell elongation. Furthermore, apoptosis was increased and the expression of Gata4, Tbx5, Nkx2.5, and Hand2 transcription factors was decreased in the Rac1(SHF) right ventricle myocardium. CONCLUSIONS Deficiency of Rac1 in the second heart field impairs elongation and cytoskeleton organization of cardiomyocytes and results in congenital septal defects, thin right ventricle myocardium, and a bifid cardiac apex. Our study suggests that Rac1 signaling is critical to cardiomyocyte polarity and embryonic heart development.

Abstract
Myocardial noncompaction (NC) is a disorder of the embryonic endomyocardial morphogenesis frequently associated with congenital cardiac abnormalities. NC predominantly affects the left ventricle (LV). Right ventricle (RV) NC may occur in association with LV involvement or in isolation. A 47-year-old woman was admitted for atrial septal defect closure. Transthoracic echocardiography revealed hypertrabeculation of the RV apex, consisting of multiple deep recesses with the entrance of blood flow in color Doppler imaging, suggestive of isolated RV hypertrabeculation/NC. The RV and right atrium (RA) were enlarged, and systolic pulmonary arterial pressure was slightly increased. Our patient's associated abnormalities were atrial septal defect (superior sinus venosus type), anomalous connection of the right upper pulmonary vein to the junction of the superior vena cava and the RA, and large patent foramen ovale. Association between atrial septal defect and partial anomalous pulmonary vein connection and isolated hypertrabeculated/noncompacted RV should be considered by cardiologists.

Abstract
Extracardiac total cavopulmonary connection between the inferior vena cava and right pulmonary artery has become the most popular Fontan modification nowadays, yielding good results. However, certain situs anomalies along with systemic venous drainage variations give rise to an issue about the best way for extracardiac conduit routing. Three cases of apicocaval juxtaposition are described. The situs was inversus with the apex and inferior vena cava on the same side (left), whereas the superior vena cava (Glenn) was located on the right in all cases. The literature is revisited and technical options are discussed. Surgery was carried out with excellent short- and midterm results.

Abstract
A 9-year-old boy was referred with a perimembranous ventricular septal defect. At birth, he had undergone a right thoracotomy with ligation of a tracheoesophageal fistula, cervical esophagostomy, and feeding gastrostomy. At 2 years of age, he had gastric tube reconstruction with a pull-through retrosternally, anterior to the heart, and an end-to-end esophagogastric anastomosis. Via a right anterolateral thoracotomy through the previous scar, the entire gastric tube was mobilized away from the sternum to facilitate a median sternotomy. With the patient supine, a median sternotomy was performed without difficulty, and the ventricular septal defect was closed under cardiopulmonary bypass.

Abstract
AIM To compare multidetector computed tomographic angiography with the gold standard cardiac catheterization and angiography in tetralogy of Fallot. METHODS In 40 consecutive patients over 5 years of age with tetralogy of Fallot, multidetector computed tomographic angiography and catheterization angiography studies were compared for intracardiac anatomy, pulmonary anatomy and indices, coronaries and collaterals. Safety parameters, relative advantages and limitations were also analyzed. RESULTS All catheterization studies required hospitalization whereas all tomographic studies were performed as outpatient procedures. The need for sedation and amount of contrast used were significantly greater in catheterization than in tomographic studies. Complications noted during catheterization were access site complications in 4 patients, cyanotic spells in 2, transient complete heart block requiring temporary pacing in 2, and air embolism in one. No complication was observed during tomographic studies. All tomographic studies were adequate, but 2 catheterization studies were inadequate. Ventricular septal defects, aortic override, level of right ventricular outflow tract obstruction, and pulmonary artery anatomy were equally assessed by both imaging modalities. However, tomographic studies missed additional small muscular ventricular septal defects. There was a linear correlation between tomographic and catheterization studies for pulmonary annulus size, artery sizes, Z-score, and Nakata index. There was complete concordance with respect to side of aortic arch and detection of collaterals. Coronary anatomy was better delineated in tomographic studies. CONCLUSIONS For preoperative evaluation of tetralogy of Fallot patients, multidetector computed tomographic angiography can be used as a reliable noninvasive alternative to cardiac catheterization angiography.

Abstract
BACKGROUND Beating-heart image-guided intracardiac interventions have been evolving rapidly. To extend the domain of catheter-based and transcardiac interventions into reconstructive surgery, a new robotic tool delivery platform and a tissue approximation device have been developed. Initial results using these tools to perform patent foramen ovale closure are described. METHODS AND RESULTS A robotic tool delivery platform comprising superelastic metal tubes provides the capability of delivering and manipulating tools and devices inside the beating heart. A new device technology is also presented that uses a metal-based microelectromechanical systems-manufacturing process to produce fully assembled and fully functional millimeter-scale tools. As a demonstration of both technologies, patent foramen ovale creation and closure was performed in a swine model. In the first group of animals (n=10), a preliminary study was performed. The procedural technique was validated with a transcardiac hand-held delivery platform and epicardial echocardiography, video-assisted cardioscopy, and fluoroscopy. In the second group (n=9), the procedure was performed percutaneously using the robotic tool delivery platform under epicardial echocardiography and fluoroscopy imaging. All patent foramen ovales were completely closed in the first group. In the second group, the patent foramen ovale was not successfully created in 1 animal, and the defects were completely closed in 6 of the 8 remaining animals. CONCLUSIONS In contrast to existing robotic catheter technologies, the robotic tool delivery platform uses a combination of stiffness and active steerability along its length to provide the positioning accuracy and force-application capability necessary for tissue manipulation. In combination with a microelectromechanical systems tool technology, it can enable reconstructive procedures inside the beating heart.

Abstract
OBJECTIVE To present our first experience in perventricular closure of ventricular septal defect, which is in our opinion, an important adjunct to current ventricular septal defect treatment options. BACKGROUND Surgical closure under cardiopulmonary bypass is the treatment of choice for a perimembranous ventricular septal defect. Percutaneous techniques have technical limitations. To date, an off-pump approach and device deployment through the wall of the right ventricle is not widespread and has only been reported from China and Germany. We think this approach is promising in selected patients. METHODS In July 2012, 7 pediatric patients with an isolated perimembranous ventricular septal defect (age range, 4 months to 8 years, mean 2.5 years, all female) with a body weight of 5 to 27 kg, mean 12.7 kg, underwent minimally invasive perventricular device closure. RESULTS In all patients, the ventricular septal defect was occluded successfully based on transesophageal echocardiographic confirmation. There were no cases of occluder dislocation noted in the operating room or in the postoperative period. No residual shunts were observed. There was no transient or persistent rhythm disorder in any of the patients. All patients were discharged 4-5 days postoperatively, in excellent physical condition. CONCLUSIONS The described off-pump approach showed excellent results. It offers such advantages as avoidance of the morbidity associated with cardiopulmonary bypass, significantly shorter hospital stay and therefore reduced costs, and a cosmetic advantage.

Abstract
Early closure of a large ventricular septal defect before the onset of elevated pulmonary vascular resistance is important. Pulmonary hypertensive events might cause significant morbidity or mortality, even when closure is performed after infancy. Therefore, treatment of pulmonary hypertension after surgery may be the most important issue affecting the prognosis. We describe successful treatment of pulmonary hypertension in a 25-year-old woman after closure of large ventricular septal defect, with inhaled nitric oxide, sildenafil, and bosentan.

Abstract
BACKGROUND We aimed to highlight the use of a minimally invasive approach in uncomplicated congenital heart surgery. PATIENTS AND METHODS We investigated retrospectively 32 children below 10 years of age who underwent elective closure of ostium secundum type (n = 27), sinus venosus type (n = 4) and ostium primum type (n = 1) atrial septal defects through a limited skin incision and partial lower sternotomy between August 2001 and December 2008. All patients had cannulation through the same incision for cardiopulmonary bypass. RESULTS A pericardial patch was used to close the defect in 8 patients and direct suturing in 24. The mean time from the skin incision to cannulation was 56 ± 23 min. Total bypass time was 27 ± 12 min, and crossclamp time was 15 ± 8 min. Mean length of hospital stay was 4 ± 2 days. We did not encounter any complications or mortality. CONCLUSIONS A minimally invasive approach, consisting of a limited skin incision and partial lower sternotomy, is a safe, reliable, and cosmetically advantageous method in uncomplicated congenital heart disease surgery, which can be performed widely, and may replace the standard approach without increasing mortality and morbidity.

Double BioDisk: a new bioprosthetic device for transcatheter closure of atrial septal defects - a feasibility study in adult sheep. Radiol Oncol 2012; 46:89-96. [PMID: 23077444 PMCID: PMC3472939 DOI: 10.2478/v10019-012-0029-8] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2012] [Accepted: 05/02/2012] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND To evaluate the long-term effectiveness and safety of a new Double BioDisk (DBD) device for closure of atrial septal defect (ASD). MATERIALS AND METHODS.: ASD was created with transeptal needle (TS) followed by balloon dilatation in 12 sheep weighing 40.1 to 64 kg (mean 55.2 ± 7.1). The ASD diameters were measured after creation and two weeks later before DBD implantation. The DBDs consists of two nitinol rings 18 to 28 mm in diameter connected with small cannulas and covered with a porcine small intestinal submucosa (SIS). They were implanted via a 10 Fr sheath. DBD effectiveness was evaluated by angiocardiography and by intra-cardiac echogram (ICE) with Doppler studies. Two animals were acute, two were followed for 6 weeks, three for 3 months, three for 6 months and two for 12 months. RESULTS TS punctures were successful in 10 sheep. In two sheep ASD was created by existing PFO dilation. The ASD size ranged from 13-15 mm (mean 14.1± 0.73 mm) after initial balloon dilation and from 9-13 mm (mean 10.06 ± 1.37 mm) after two weeks. In all animals none of the successfully implanted DBDs spontaneously embolized on release or on follow up. ICE demonstrated no shunting around the DBDs during follows ups. Macroscopic and histologic evaluation of the 6, 12, 24 and 52 weeks animals showed that DBDs were well incorporated in the atrial septum with complete shunt closure. The SIS showed progressive remodeling with the host cells, including endothelization of the DBD devices. CONCLUSIONS ASD closure with the Double BioDisk is safe and effective in adult sheep.

Abstract
The objective was to report the surgical results following failed transcatheter intervention for closure of ventricular septal defects (VSDs). This study is a retrospective analysis of patients (n = 9) from Xijing Hospital (Xi'an, China) with failed transcatheter intervention for VSDs who subsequently underwent open heart surgery. Five patients experienced complications during transcatheter intervention, including third-degree atrioventricular block (III° AVB) (n = 2), aortic incompetence (n = 2), or tricuspid incompetence (n = 1). The devices were immediately removed in the catheterization laboratory followed by open heart surgery to repair VSDs. Four patients experienced complications after transcatheter intervention; one patient's device was displaced into the right ventricle, and 3 patients had III° AVB. These patients underwent surgery to retrieve the devices and to repair VSDs. All cardiac surgery was performed under general anesthesia and under cardiopulmonary bypass. Postoperatively, all patients recovered uneventfully with no deaths or complications. The patients with III° AVB after device implantation recovered sinus rhythm postoperatively, and tricuspid apparatus injuries were surgically repaired with valvuloplasty. Transcatheter interventional VSD closure is safe and effective, but only under the conditions of strict patient selection, proper technique, and device application. Once severe complications are observed and diagnosed, devices should be retrieved immediately, and open heart surgery should be performed to avoid further injury.

Abstract
OBJECTIVE To study the feasibility, efficacy, and safety of total percutaneous correction of a tetralogy of Fallot variant with dominant pulmonary valve stenosis. DESIGN Percutaneous correction of a variant of tetralogy of Fallot with dominant pulmonary valve stenosis, on the basis that there are transcatheter methods for the correction of malalignment-type ventricular septal defect (VSD) (transcatheter patch) and valvar pulmonary stenosis (balloon valvoplasty). PATIENTS Two patients with tetralogy of Fallot, 4 and 7 years old, were admitted for percutaneous correction. Their aortic saturations were 72% and 88%. Both had severe right ventricular outflow obstruction with dominant valvar pulmonary stenosis with total gradients of 120 and 70 mm Hg. Large malalignment subaortic VSDs, 14 and 16 mm in diameter, were present. The first patient had a previous percutaneous correction of a small atrial septal defect and an aortopulmonary collateral. INTERVENTIONS Balloon valvoplasty was first performed, followed by balloon test occlusion of the VSD and double balloon patch occlusion. Forty eight hours after implantation the supporting balloons were extracted, releasing the patches. RESULTS Both patients became acyanotic with oxygen saturations of 96%. There was mild residual infundibular stenosis with 40 and 30 mm Hg gradients. Both VSDs were effectively occluded with only trivial residual shunts. One patient developed mild haemolysis, which resolved spontaneously in a few days. Both patients were doing well at six and 12 months' follow up visits. CONCLUSIONS Total percutaneous correction of the tetralogy of Fallot variants with dominant pulmonary valve stenosis is feasible and successful. Larger clinical trials are required to further assess effectiveness and safety.

Ruptured aneurysm of the right sinus of valsalva associated with a ventricular septal defect and an anomalous coronary artery. Tex Heart Inst J 2005; 32:555-9. [PMID: 16429902 PMCID: PMC1351829] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/06/2023]
Abstract
Aneurysms of the sinus of Valsalva are extremely rare. Ruptured aneurysms of the sinus of Valsalva are frequently associated with other congenital defects, particularly with ventricular septal defect, aortic valve regurgitation, and bicuspid aortic valve. We describe the case of a 26-year-old man who had a ruptured aneurysm of the right coronary sinus, a ventricular septal defect, and an anomalous origin of the right coronary artery. Successful surgical correction of the aneurysm and ventricular septal defect was performed with patch repair and aortic valve replacement. A review of the English-language medical literature revealed only 1 other case of a sinus of Valsalva aneurysm associated with a ventricular septal defect and an anomalous coronary artery. Previously published reports of the coexistence of a single coronary artery with a sinus of Valsalva aneurysm or with a ventricular septal defect, and their management, are discussed herein.

Complete atrioventricular canal defect: surgical considerations. Tex Heart Inst J 1992; 19:239-43.

Abstract
Complete atrioventricular canal defect is a serious and complex cardiac anomaly that is frequently associated with other congenital cardiac defects. Its natural course is ultimately fatal; 80% of children born with this defect will die within 2 years. Long-term medical therapy for complete atrioventricular canal defect is ineffective; therefore, either palliative or curative surgery is required. The risk of corrective surgery for this defect in infancy has steadily decreased because of improvements in surgical techniques, anesthesia, and postoperative management. This report describes our current surgical technique for primary corrective repair of complete atrioventricular canal defect, with a review of recent results of this procedure in 34 patients.
