Echocardiographic tools for pacemaker optimization of ventricular function in an infant following surgical repair for double outlet right ventricle.

ABSTRACT: A case of an infant, following surgical repair for double outlet right ventricle, who developed low cardiac output syndrome and complete heart block that required insertion of a pacemaker is presented. The infant underwent optimization of his ventricular function to determine whether pacing the right ventricle or left ventricle or both would improve cardiac function. Using standard two-dimensional echocardiography and Doppler imaging, tissue synchronization imaging, and two-dimensional speckle-tracking strain analysis, improvement in cardiac output and function was demonstrated. The present case highlights the usefulness of newer echocardiographic techniques in pacemaker optimization in the acute postoperative setting.

Transcatheter ventricular septal defect (VSD) creation for restrictive VSD in double-outlet right ventricle.

Project description:BackgroundDouble-outlet right ventricle (DORV) with a restrictive ventricular septum is a rare but highly morbid phenomenon that can be complicated by progressive left ventricular hypertrophy, arrhythmias, aneurysm formation, severe pulmonary hypertension, and death in the newborn. Surgical creation or enlargement of a ventricular septal defect (VSD) is palliative but may damage the conduction system or the atrioventricular valves in the newborn. This report presents a transcatheter approach to palliation for a newborn that had DORV with a restrictive ventricular septum.Methods/resultsA full-term infant girl (2.9 kg) referred for hypoxia (80% with room air) and murmur was found to have DORV, interrupted inferior vena cava, and restrictive VSD (95-mmHg gradient). Transhepatic access was performed, and an internal mammary (IM) catheter was advanced through the atrial septal defect and into the left ventricle. By transesophageal echocardiographic guidance, a Baylis radiofrequency perforation wire was used to cross the ventricular septum, and the defect was enlarged using a 4-mm cutting balloon. A bare metal stent then was deployed to maintain the newly created VSD. The patient did well after the procedure but required pulmonary artery banding 4 days later. She returned 5 months later with cyanosis and the development of obstructing right ventricle muscle bundles, requiring further surgical palliation.ConclusionsThis report describes the first transcatheter creation of VSD in DORV with a restrictive ventricular septum in a newborn infant. Use of the radiofrequency catheter in combination with cutting balloon dilation and stent implantation is an efficient method for creating a VSD in such a patient.

Unguarded left atrioventricular orifice: An unusual cause of hypoplastic left ventricle and double-outlet right ventricle with intact ventricular septum.

Project description:An unguarded atrioventricular orifice is an extremely rare congenital anomaly characterized by the absence of the atrioventricular valve in varying proportions. While atresia of the mitral or aortic valves are usually described as causes for hypoplastic left heart, our case highlights the role of free atrioventricular valve regurgitation and consequent volume loss of the left heart, giving rise to a small left ventricle. There was an associated double-outlet right ventricle and Type B aortic interruption. While we have attempted to discuss the complex management options in this scenario, the parents decided to withdraw further care.

Right Ventricular Angiosarcoma Compressing the Left Ventricle.

Project description:Highlights•Echocardiography is usually the first imaging modality ordered for evaluation of a cardiac mass.•Although echocardiography cannot define the histopathology of a mass, it can identify the presence, location, and tissue characteristics of the mass, which can thus narrow the differential diagnosis.•Echocardiography is useful in evaluating tumor sequelae such as blood flow obstruction, valvular regurgitation, and myocardial dysfunction.

Ablation for idiopathic left ventricular tachycardia in a patient with double outlet right ventricle who underwent Fontan operation: a case report.

Project description:BackgroundThe incidence of ventricular tachycardia (VT) in patients following Fontan operation is reported as 3.5%. Furthermore, in patients with repaired double outlet right ventricle (DORV), scar-related VT and outflow tract VT have been reported; however, Purkinje-related VT has not previously been reported. In this report, we present the case of idiopathic left VT (ILVT) in a patient with DORV who underwent Fontan operation.Case summaryA 31-year-old man was diagnosed as having DORV with complete atrioventricular defect at birth. When he was 17 years old, he underwent surgical repair, including extracardiac Fontan operation and common atrioventricular valve replacement. Five years later, VT was detected. Since some medications were ineffective in suppressing VT, he was referred to our hospital for definitive treatment. Ventricular tachycardia was induced by atrial and ventricular programmed electrical stimulations. The mechanism of the VT was determined to be re-entry. The earliest activation site was located at the mid-inferior septum of the hypoplastic left ventricle, in which Purkinje potentials were observed before the local ventricular electrogram. Radiofrequency catheter ablation (RFCA) was performed at this site to eliminate VT.DiscussionMost VTs originate from surgical scars in patients with congenital heart disease. Catheter ablation was feasible in scar-related VT. To the best of our knowledge, this is the first report of ILVT treated successfully with RFCA in a DORV patient who had undergone Fontan operation.

Obesity and right ventricular structure and function: the MESA-Right Ventricle Study.

Project description:BackgroundThe relationship between obesity and right ventricular (RV) morphology is not well studied. We aimed to determine the association between obesity and RV structure and function in a large multiethnic population-based cohort.MethodsThe MESA-Right Ventricle Study measured RV mass and volumes by cardiac MRI in participants aged 45 to 84 years without clinical cardiovascular disease in the Multi-Ethnic Study of Atherosclerosis (MESA). Participants were divided into three categories based on BMI: lean ( ? 24.9 kg/m(2)), overweight (25-29.9 kg/m(2)), and obese ( ? 30 kg/m(2)).ResultsThe study sample included 4,127 participants. After adjustment for demographics, height, education, and cardiovascular risk factors, overweight and obese participants had greater RV mass (6% and 9% greater, respectively), larger RV end-diastolic volume (8% and 18% greater, respectively), larger RV stroke volume (7% and 16% greater, respectively), and lower RV ejection fraction ( ? 1% lower) than lean participants (all P < .001). These findings persisted after adjusting for the respective left ventricular (LV) parameters.ConclusionsOverweight and obesity were independently associated with differences in RV morphology even after adjustment for the respective LV measure. This association could be explained by increased RV afterload, increased blood volume, hormonal effects, or direct obesity-related myocardial effects.
