Pulmonary artery dissection secondary to ventricular septal defect and pulmonary valve stenosis.

The aortic short axis view demonstrated the widening of the pulmonary artery and the membrane-like echo in the pulmonary artery divided it into true lumen and false lumen. And the flow of the ruptured openings on the band-like echo was clearly revealed by Color Doppler.

Complete Percutaneous Retrieval of Migrated VSD Occluder Device from the Pulmonary Artery: Management of a Catastrophic Complication.

Transcatheter closure of muscular ventricular septal defects (VSD) remains a safe and effective method with low complication rates. However, device migration can pose a significant challenge to interventional cardiologists due to potential mortal consequences. A 21-year-old female presented to our clinic with exertional dyspnea and was diagnosed with a muscular VSD. The defect was percutaneously closed using an Amplatzer occluder device. On the first post-procedural day, the patient experienced repeated episodes of coughing and mild hemoptysis. Imaging revealed migration of the VSD occluder device to the right pulmonary artery (PA). Percutaneous retrieval of the device was then decided upon. The right PA was accessed using a hydrophilic guidewire and a pigtail catheter. This catheter was exchanged for an 8-Fr sheathless guide catheter, and a 6-Fr Judkins right catheter was advanced into the right PA through the sheathless guide catheter using the mother-and-child technique. Multiple attempts using a snare were made to retrieve the migrated device. Eventually, the proximal marker point, the hub of the device, was grasped and pulled back from the PA, then externalized through the sheath without the need for surgical cutdown. Our report represents a case of complete percutaneous retrieval of an embolized VSD occluder device from the PA.

Double-chambered right ventricle in a patient with pulmonary atresia and ventricular septal defect.

Double-chambered right ventricle is a rare form of right ventricular outflow tract obstruction caused by anomalous hypertrophy of muscle bundles in right ventricle. Cases most often occur in children and rarely in adults. Most cases (80-90%) are associated with ventricular septal defect. We describe a case of pulmonary atresia and ventricular septal defect with double-chambered right ventricle. The interesting clinical findings, ECG, echocardiography and angiocardiography features are described here.

Echocardiographic Comparison of Left Ventricular Systolic Function and Aortic Blood Flow Velocimetry in Children with Ventricular Septal Defect.

BACKGROUND: The assessments of left ventricular (LV) longitudinal systolic dynamics in children with ventricular septal defect (VSD) have achieved a major milestone in the evaluation of LV systolic function. OBJECTIVES: This study aims to evaluate the LV function, LV mass (LVM), and the descending aorta blood flow in children with VSD compared to that obtained in age and sex-matched controls. RESULTS: The mean LVM of the control, 113.5 ± 123.9 was higher than that of those who had VSD, 75.8 ± 83.9, and the difference in mean was found to be statistically significant (Mann-Whitney U = 2.322, P = 0.022). The mean EF of the control, 67.9 ± 10.3 was comparable to that of those with VSD, 65.6 ± 13.9, (Student's t = 1.223, P = 0.223). Similarly, the mean descending aorta blood flow of control, 1.6 ± 2.2 was comparable to that of those with VSD, 3.9 ± 16.1, (Mann-Whitney U = 1.002, P = 0.321). There was a very weak positive correlation between LVM and descending aorta blood flow among the subjects (n = 85, r = 0.117, P = 0.425). There was a very weak negative correlation between LVM and descending aorta blood flow among control. (n = 85, r = -0.065, P = 0.609). CONCLUSION: The LVM among children with VSD is lower than controls but there is no difference between LV function in subjects and controls. There is a linear increase of LVM with descending aorta blood flow.

Differential Clubbing and a Triad of Patent Ductus Arteriosus, Ventricular Septal Defect and Supravalvular Ring Mitral Stenosis: A Case Report.

It is not uncommon for congenital heart defects to occur in clusters. Those involving a right to left heart shunt commonly cause cyanosis and finger clubbing. Differential clubbing involving only the lower limb digits is a strong pointer to the presence of patent ductus arteriosus with reversal of shunt. We report a case of 25-year-old man with effort intolerance and differential clubbing. He was found to have the uncommon triad of patent ductus arteriosus, ventricular septal defect and supravalvular ring mitral stenosis. The presence of differential clubbing on a background of patent ductus arteriosus usually indicates a reversal of shunt and negates surgical intervention. This general rule may however not apply with co-existing mitral stenosis as the elevated pulmonary pressure may be predominantly post-capillary. The finding of mitral stenosis in a patient with patent ductus arteriosus and differential limb clubbing may signify a good prognostic surgical outcome.

Il n'est pas rare que des malformations cardiaques congénitales surviennent en clusters. Celles impliquant un shunt cardiaque droitegauche provoquent souvent une cyanose et un hippocratisme digital. L'hippocratisme digital différentiel touchant uniquement les orteils des membres inférieurs est un indicateur fort de la présence d'un canal artériel persistant avec inversion du shunt. Nous rapportons le cas d'un homme de 25 ans présentant une intolérance à l'effort et un hippocratisme digital différentiel. Il a été diagnostiqué avec la triade peu commune de canal artériel persistant, de communication interventriculaire et de sténose mitrale à anneau supravalvulaire. La présence d'un hippocratisme digital différentiel sur un fond de canal artériel persistant indique généralement une inversion du shunt et exclut une intervention chirurgicale. Cependant, cette règle générale peut ne pas s'appliquer en présence d'une sténose mitrale concomitante, car la pression pulmonaire élevée peut être principalement post-capillaire. La découverte d'une sténose mitrale chez un patient atteint de canal artériel persistant et d'un hippocratisme digital différentiel peut indiquer un bon pronostic pour l'intervention chirurgicale.

Percutaneous Closure of Hemodynamically Significant Postoperative Residual Ventricular Septal Defects.

The experience with percutaneous closure of postoperative residual ventricular septal defects (VSDs) is expanding with improved device technology and techniques. To report our experience with percutaneous closure of residual VSDs after cardiac surgeries. Retrospective clinical data review of patients who had percutaneous closure of postoperative residual VSDs at our institution between 2010 and 2022. Patients' demographics, procedural, and follow-up data were looked at. Twelve patients (50% males) with a median age of 9.2 years (range 0.9-22) were identified. Baseline surgeries were 8 tetralogy of Fallot corrections, 2 pulmonary bandings for large muscular VSD (mVSD) including 1 coarctation repair, 1 atrioventricular septal defect repair, 1 sub-aortic membrane resection-induced iatrogenic VSD, 1 isolated VSD closure, and 1 additional mVSD. Median duration between baseline surgery and percutaneous VSD closure was 2.2 years (range 0.2-8.3). Residual VSD shunting was secondary to surgical patch leakage in 8/12 patients. The median angiographic defect diameter was 6.8 mm (range 4.8-14). The defect was balloon-calibrated in 3/12 patients. Defects were tackled retrogradely in 3/9 patients. Amplatzer Membranous VSD occluder (n = 1), Lifetech Multifunctional (n = 5), Membranous (n = 1) and muscular VSD occluders (n = 2) and Occlutech Membranous (n = 1) and Muscular (n = 2) VSD occluders were used. The procedure was successful in 10/12 patients. Two devices embolized to the pulmonary artery and were snare-retrieved. Both patients were referred for surgery. The median follow-up was 1.3 years (range 0.1-12). Six-month ultrasound showed one trivial residual shunt and one mild right ventricular outflow obstruction. One patient is receiving targeted therapy for pulmonary hypertension at 2 years of follow-up. Transcatheter closure of postoperative residual VSDs is a feasible yet challenging intervention. Procedural complications can be encountered.

Ventricular septal defect following mitral valve replacement.

Mitral valve surgery (MVS), with repair preferred to replacement, is a common procedure for the treatment of severe primary mitral regurgitation related to leaflet prolapse. Structural complications after MVS include left ventricular outflow obstruction, paravalvular leak and atrial septal defect. Intraoperative transoesophageal echocardiography and predischarge transthoracic echocardiography (TTE) specifically screen for these complications. Ventricular septal defect (VSD), a known complication after aortic valve surgery, is rarely reported after MVS. Recently, unsuccessful valvuloplasty prior to replacement was suggested as a risk factor. We present such a case and explore mechanisms with advanced cardiac imaging. In this case, the patient was found to have an elongated membranous septum that likely predisposed her to septal injury. Finally, we provide guidance on specific transoesophageal/transthoracic echocardiography views to avoid a missed diagnosis.

Early Clinical Outcomes in Infants with Prenatally Diagnosed Perimembranous and Muscular Ventricular Septal Defects (VSDs).

Isolated ventricular septal defect (VSD) is often associated with good clinical outcomes. However, infants prenatally diagnosed with VSD are often recommended for delivery at tertiary care centers. The aim of our study was to determine the odds of neonatal intensive care unit (NICU) admission in infants with persistent isolated VSD and complicated VSD, where an infant is affected by VSD and other genetic/structural abnormalities. We performed a retrospective cohort study, with data collected from a single academic institution from June 2018 to March 2023. Individuals with prenatally diagnosed VSD, in the absence of any other heart defects, were included in this study. The primary outcome was admission to the NICU. Multivariable logistic regression was used to assess associations. The association between persistence of VSD and NICU admission was adjusted for maternal age, fetal genetic abnormalities, fetal extracardiac abnormalities, and gestational age at the time of delivery. The association between complicated VSD and NICU admission was adjusted for maternal age and gestational age of the infant at the time of delivery. The odds of NICU admission were similar in infants with persistent isolated VSD and VSD that closed in utero (adjusted OR 1.31, 95% CI 0.30-5.61). However, infants with complicated VSD were at increased risk of NICU admission (adjusted OR 15.52, 95% CI 2.90-82.92). The risk of NICU admission was only increased in infants whose VSD was complicated by another genetic/major structural abnormalities. Therefore, women whose infants are prenatally diagnosed with VSD alone may not require delivery at tertiary care centers.

Double-Chambered Left Ventricle Diagnosed in Fetus and Follow-up During the First Year of Life: A Case Report.

Double-chambered left ventricle (DCLV) is a rare congenital cardiac lesion. It is usually an incidental finding in children and young adults. Diagnosis during fetal life is exceedingly rare. We report a case of DCLV diagnosed in the prenatal period associated with a ventricular septal defect (VSD). Transthoracic echocardiographic and magnetic resonance imaging confirmed the prenatal findings. At seven-month follow-up, the baby was asymptomatic. Transthoracic echocardiographic check-up revealed spontaneous closure of the VSD and stable aspect of the main left ventricle and the accessory chamber.

All that flows across the ventricular septum are not ventricular septal defects.

Coronary cameral fistula is a rare congenital anomaly and clinical presentation depends on the location of the defect, degree of shunting, and associated complications. We present a case of coronary cameral fistula where segmental analysis by echocardiogram helped us to avoid misdiagnosis as a ventricular septal defect.

Use of the Occlutech pmVSD Device for Hybrid Closure of a Large Mid-Muscular Ventricular Septal Defect in a Small Infant Born With Hypoplastic Aortic Arch.

We describe the perventricular device closure of a large mid-muscular ventricular septal defect (VSD) in a 2.9 kg infant born with hypoplastic aortic arch and VSD using an Occlutech perimembranous occluder. In this case, the anatomy required a short low-profile device and hence a perimembranous occluder was used. To our knowledge, this is the first described use of this device for hybrid closure of a muscular VSD and the application of this technique in a patient <3 kg.

A Retrospective Study in Occluding Sub-arterial Ventricular Septal Defect.

To assess the safety and effectiveness of utilizing eccentric occlusion for the treatment of sub-arterial ventricular septal defects, we performed a retrospective study on the classification and analysis of relevant cases. A total of 105 patients with a minimally invasive incision were enrolled in this study, from April 2018 to September 2022. All patients underwent treatment of transthoracic sub-arterial ventricular septal defect occlusion. We analyzed the causes of closure failure, indication, and complication. Briefly, the closure device was successfully implanted in 78 cases (74.2%) with a mean age of 31.4 ± 31.8 months, VSD size of 4.3 ± 0.9 mm, and device size of 6.0 ± 1.1 mm. However, 27 cases (25.8%) required cardiopulmonary bypass due to failure of occlusion. The reasons for failure included 13 cases with worsened aortic regurgitation, two cases with worsened aortic valve prolapse, one case with worsened mitral regurgitation, eight cases with significant residual shunt, and three cases with deviated occlusion morphology. During the 1-36-month follow-up visit, no cases experienced displacement of the eccentric umbrella, shedding, or arrhythmia. All residual shunts resolved during the visit. We concluded that occlusion for sub-arterial VSD has sufficient security and feasibility, under the strict control of surgical indications, appropriate choice of occluder and precise perioperative management.

Preliminary experience with transcatheter closure of wind-sock-like perimembranous ventricular septal defects using Amplatzer Vascular Plug IV devices.

Amplatzer Vascular Plug IV (Abbott, USA) is usually used for the occlusion of abnormal tortuous vessels and has not been tried for the transcatheter closure of perimembranous ventricular septal defects with wind-sock morphology. Here, we report on three successful cases of perimembranous ventricular septal defect transcatheter closure using Amplatzer Vascular Plug IV. We did not observe residual shunting or new onset of complications during follow up. These preliminary positive results advocate the application and suitability of Amplatzer Vascular Plug IV for closing wind-sock-like perimembranous ventricular septal defects.

Intracardiac Three-Dimensional Image as Surgical Decision-Making Tool of Congenital Heart Disease.

This study aimed to evaluate the anatomical reproducibility of a preoperative intracardiac 3D image (IC image) created using computed tomography, and to investigate its usefulness as a surgical decision-making tool. Between 2012 and 2022, ventricular septal defect (VSD) patients, and double outlet right ventricle (DORV) or transposition of the great arteries (TGA) with pulmonary stenosis (PS) patients who underwent cardiac surgery and had preoperative computed tomography were enrolled. SYNAPSE VINCENT® (Fujifilm) was used to create an IC image which was analyzed retrospectively. In 14 VSD patients, the diagnostic consistency rate in the Soto classification with intraoperative findings was 100% (14/14) for IC image versus 64% (9/14) for transthoracic echocardiography (P = 0.04). The defect size showed a higher correlation coefficient with IC image (0.837, P = 0.001) than with transthoracic echocardiography (0.567, P = 0.034). In 11 DORV/TGA with PS patients, the diagnostic consistency rate in the Lev classification was 100% (9/9) for IC image versus 77% (7/9) for transthoracic echocardiography (P = 0.47). The secondary interventricular foramen (SVF)/left ventricular outflow tract (LVOT) ratio by IC image was significantly smaller in the biventricular-repair group (median 0.71, IQR 0.67-1.06) than in the univentricular-repair group (median 1.79, IQR 1.53-2.42) (P = 0.006). An IC image is useful as a surgical decision-making tool for simple VSDs and complex congenital heart diseases such as DORV or TGA with pulmonary stenosis. The SVF/LVOT ratio determined from the IC image may be a useful indicator for avoiding LVOT obstruction.

Chest pain due to coronary artery compression in an adult with CHD.

A 47-year-old with repaired ventricular septal defect and pulmonary valve stenosis as a child presents with chronic intermittent chest pain. CT evaluation for transcatheter pulmonary valve replacement revealed right coronary artery compression between a sternal wire and dilated right ventricle. Removal of the sternal wire resulted in improved symptoms.

Tricuspid atresia with atrial and ventricular septal defects in a kitten.

A 45-days-old mixed-breed female cat was referred to a veterinary specialty hospital for evaluation due to poor general condition, dyspnea of possible cardiac origin, and a heart murmur. The results of the physical examination, thoracic radiography, and echocardiography led to a diagnosis of hypotrophy of the right ventricle, tricuspid atresia, and atrial septal defect. Cardiovascular pathological findings confirmed the clinical diagnosis in addition to the observation of a ventricular septal defect. To the authors' knowledge, this is the first report of tricuspid atresia with atrial septal defect and ventricular septal defect in a cat.
