Project description:Iatrogenic valvular regurgitation following cardiac surgery has been reported as a result of leaflet perforation or entrapment. Due to its central location, the aortic valve is one of the most vulnerable structures for iatrogenic injuries. Proper assessment of the aortic valve by transesophageal echocardiography (TEE) should be done after a cardiac surgery in the periaortic area. We hereby report a case of iatrogenic aortic regurgitation which was developed after primary closure of perimembranous ventricular septal defect. It was timely diagnosed by TEE after termination of cardiopulmonary bypass and helped in further management.

Project description:BackgroundSurgical and perioperative improvements permit earlier repair of partial and transitional atrioventricular septal defects (AVSD). We sought to describe contemporary outcomes in a multicenter cohort.MethodsWe studied 87 patients undergoing primary biventricular repair of partial or transitional AVSD between June 2004 and February 2006 across seven North American centers. One-month and 6-month postoperative data included weight-for-age z-scores, left atrioventricular valve regurgitation (LAVVR) grade, residual shunts, and left ventricular ejection fraction. Paired methods were used to assess 6-month change.ResultsMedian age at surgery was 1.8 years; median weight z-score was -0.88. Median days for ventilation were 1, intensive care 2, and hospitalization 5, all independent of age, with 1 in-hospital death. At 1 month, 27% (16 of 73) had ejection fraction less than 55%; 20% (17 of 87) had significant LAVVR; 2 had residual shunts; 1 each had subaortic stenosis and LAVV stenosis. At 6 months (n = 60), there were no interim deaths, reinterventions, or new development of subaortic or LAVV stenosis. Weight z-score improved by a median 0.4 units (p < 0.001), especially for underweight children less than 18 months old. Left atrioventricular valve regurgitation occurred in 31% (change from baseline, p = 0.13), occurring more frequently in patients repaired at 4 to 7 years (p = 0.01). Three patients had ejection fraction less than 55%, and 1 had a residual atrial shunt.ConclusionsSurgical repair for partial/transitional AVSD is associated with low morbidity and mortality, short hospital stays, and catch-up growth, particularly in underweight children repaired between 3 and 18 months of age. Left atrioventricular valve regurgitation remains the most common residual defect, occurring more frequently in children repaired after 4 years of age.

Project description:Transesophageal echocardiography has advantages over transthoracic technique in defining morphology of atrial structures. Even though real time three-dimensional echocardiographic imaging is a reality, the off-line reconstruction technique usually allows to obtain higher spatial resolution images. The purpose of this study was to explore the accuracy of off-line three-dimensional transesophageal echocardiography in a spectrum of atrial septal defects by comparing them with representative anatomic specimens.

Project description:BackgroundThe assessment of interatrial septum (IAS) requires a standardized, systematic approach, including two-dimensional transthoracic echocardiography (2D TTE), 2D transesophageal echocardiography (2D TEE), and three-dimensional (3D) TEE. Although 2D TEE has been widely used for the preoperative assessment of atrial septal defect (ASD), its ability to provide reliable information is often limited due to the structural characteristics of IAS. The introduction of 3D TEE provides a unique "en face" view of IAS, which allows the visualization and accurate measurements of diameters, area, and rims of ASD. Hence, appropriate ASD imaging information is particularly important in successful transcatheter closure.MethodsIn this retrospective study, 2D TTE/TEE, and 3D TEE were performed before ASD closure, with 2D minimal and maximal diameters, areas, and residual rims being recorded. Adequate 3D TEE imaging data sets were collected and then analyzed. ASD related parameters were compared using different echocardiography. Patients who underwent ASD closure completed a clinical follow-up.ResultsThe mean defect maximal diameter and aperture area by 3D TEE was significantly larger than that of the corresponding 2D TEE (P<0.05). There was no statistical difference in the minimal and maximal diameter or area by TEE for circular-shaped ASDs. For oval ASDs, mean minimal diameter on 2D TEE was larger than that on 3D TEE. The mean maximal diameter measured using 2D TEE was smaller than the 3D TEE measurement (16.0±7.1 vs. 19.8±8.6; P<0.05). For complex-shaped defects, there were statistical differences in minimal and maximal diameter between TEEs. Furthermore, 2D and 3D TEE had a longer superior vena cava (SVC) residual rim than did 2D TTE (P<0.05). The 3D TEE residual rims of the inferior vena cava (IVC) was significantly larger than the corresponding 2D TEE. There was a very strong correlation between the residual rim measurements using 3D and 2D TEE. However, the limits of agreement between 2D and real-time 3D TEE measurements were more apparent in the IVC rim group than in the other groups.ConclusionsOur study confirms the value of 3D TEE in assessing ASD shape and size reported by previous studies, and is also the first to accurately and systematically characterize ASD residual rim in complex ASDs.

Project description:Right atrial (RA) aneurysms are rare entities reported in the literature. Affected patients are usually asymptomatic, but sometimes, they tend to present with arrhythmias or even heart failure if big. They may form a nidus for thrombus formation and subsequent thromboembolic complications. We report a coincidental finding of a RA aneurysm in a 22-year-old female with the atrial septal defect and mitral valve prolapse, causing moderate mitral regurgitation. The aneurysm was detected incidentally on transesophageal echo after anesthetic induction for elective surgery of the primary pathology. The mitral valve was repaired, and the atrial septal defect was closed. The aneurysm was excised in toto and RA wall repaired.

Project description:This study described the first experience with 3-dimensional multiplanar reconstruction transesophageal echocardiography to guide percutaneous alcohol septal ablation. This study demonstrated that 3-dimensional transesophageal echocardiography multiplanar reconstruction allowed for simultaneous assessment of the targeted myocardial area from left ventricular base to apex, akin to imaging seen with spatial imaging with cardiac magnetic resonance. (Level of Difficulty: Intermediate.).

Project description:ObjectiveReview of intraoperative anesthetic challenges and the role of transesophageal echocardiography in children with sinus venosus atrial septal defect and partial anomalous pulmonary venous drainage undergoing Warden repair.DesignA retrospective observational case series. METHODOLGY: Pediatric patients who underwent Warden repair between October 2011-September 2015 were recruited. Their preoperative clinical details, anesthetic techniques, intraoperative TEE findings and postoperative events were recorded from the medical records. The categorical variables and the continuous variables were expressed as number (percentages) and mean ? SD respectively.ResultsA total of 35 patients were operated for Warden repair during the study period. Anesthesia was induced with the aim to prevent any fall in pulmonary vascular resistance. The right internal jugular vein was cannulated under ultrasound guidance using a short length cannula to monitor right superior vena cava pressure. Intraoperative TEE revealed the drainage of PAPVC high into RSVC in 22 patients. Persistent LSVC was found in 9 patients. After repair, TEE imaging detected a high gradient at Warden anastomotic site in 5 patients and 3 of them required revision of surgery. Rerouted pulmonary veins required surgical correction in 2 patients in view of obstruction. None of them had pulmonary venous and SVC obstruction in the postoperative period.ConclusionThe primary aim of anesthesia is to avoid any fall in PVR. Right IJV cannulation can be beneficial. The intraoperative TEE can help in delineating the anatomy of lesion and detecting anastomotic site obstruction.
