Project description:Transcatheter correction of superior sinus venosus atrial septal defect (SVASD) is being considered as an alternative to surgery in selected patients. We present the case of a 42-year-old woman with SVASD and partial anomalous venous connection of the right upper pulmonary vein (RUPV), who underwent transcatheter correction with self-expanding aortic stent graft, following feasibility assessment by balloon occlusion. Hemodynamic parameters and angiography demonstrated successful closure of the SVASD without any residual shunt and unobstructed return of RUPV to the left atrium. She developed cardiac tamponade after a few hours despite pericardial drain and underwent emergency exploratory thoracotomy. This revealed leak from a small rent in the ascending aortic wall adjacent to superior vena cava (SVC) caused by barbs of the stent protruding from SVC, without any leak in SVC. This was repaired with suture and further Teflon was placed around the barbs in SVC to prevent further injury. We also discuss the possible reason for this complication, considering our successful previous two cases with the same stents. This case highlights the importance of assessing the relationship between SVC and aorta to decide about the cranial placement of the aortic stent either by computed tomography prior or by contrast aortogram during the procedure. <Learning objective: Transcatheter correction of superior sinus venosus atrial septal defect is becoming an appropriate alternative option for cardiac surgery. There are multiple reports of this technique in the literature - mostly with balloon expandable stents, and few with self-expanding stents placed in superior vena cava (SVC). We present an unanticipated complication of self-expanding aortic stent in this situation and its management, highlighting the need for assessing the relationship between SVC and aorta to decide about the appropriate placement of stent.>.

Project description:In contrast with transthoracic echocardiography, transesophageal echocardiography provides a sure way to make the diagnosis of sinus venosus atrial septal defect; on the other hand this abnormality is more complex than that seen with the secundum atrial septal defect, and inexperienced operators may fail to recognize properly the defect. In front of a high reported sensitivity using transesophageal echocardiography, specificity is difficult to assess, due to possible underreporting of diagnostic errors. We describe a false positive diagnosis of sinus venosus atrial septal defect, in the setting of enlarged right chambers of the heart because of pressure overload. Modified anatomy of the heart, together with the presence of a prominent linear structure(probably Eustachian Valve) and an incomplete examination in this case made image interpretation very prone to misinterpretation. In this anatomical setting transesophageal longitudinal "bicaval" view may be sub-optimal for examining the atrial septum, potentially showing false images that need to be known for correct image interpretation. Nonetheless, a scan plane taken more accurately at the superior level would have demonstrated/excluded the pathognomonic feature of sinus venosus atrial septal defect in the high atrial septum, between the fatty limbus and the inferior aspect of the right pulmonary artery; moreover TEE allows morphological information about the posterior structures of the heart that need to be investigated in detail for a complete diagnosis.

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.

Project description:Dilated cardiomyopathy, heart failure and atrial septal defects are well-recognised entities in isolation, but are rarely seen together. Now that 90% of children with congenital heart disease survive into adulthood, such combinations of disease are increasingly seen in adult cardiology. While most young patients with dilated cardiomyopathy respond well to medical therapy, some do not, and require more invasive management. We describe a 32 year-old man with dilated cardiomyopathy and a sinus venosus-type atrial septal defect associated with a remarkable pulmonary to systemic flow ratio of 5:1. We propose that the atrial septal defect blunted his heart failure symptoms by serving as a 'pop-off' valve and limiting pulmonary congestion. The patient ultimately failed medical management and received a left ventricular assist device. The case is presented along with a discussion of this unique pathophysiology and a brief review of the literature in this rapidly evolving field.

Project description:This study aimed to present a case of 33-year old man who was admitted with a history of one week headache and acute diplopia. No important finding was reported in his past medical history. Brain CT-scan revealed a large mass lesion in left parieto-occipital area with prominent vasogenic edema and midline shift. Brain magnetic resonance imaging (MRI) showed a mass with size of 5*4*5 centimeter with ring enhancement. After cranial surgery and removing the mass, transthoracic and transesophageal echocardiography (TEE) were conducted to find the source of brain abscess. Right ventricular (RV) and right atrial (RA) enlargement, significant left to right shunt, normal left ventricular (LV) and RV function, bidirectional shunt in addition to moderate size superior sinus venosus type atrial septal defect (ASD) were detected. Considering that most of brain abscesses have hematogenous source, a complete cardiac evaluation including TEE with contrast study is suggested for evaluation of patients with brain abscess.

Project description:A 63-year-old man with cirrhosis, hepatocellular carcinoma, and coagulopathy was diagnosed with a sinus venosus atrial septal defect (ASD) and partial anomalous pulmonary venous return (PAPVR) of the right upper pulmonary vein (RUPV). Transcatheter repair by positioning a stent graft in the superior vena cava was planned. Based on three-dimensional (3D) reconstruction of gated cardiac CTA, a 28 mm × 7 cm Endurant II® aortic extension stent graft (Medtronic, MN) was chosen. A 3D model printed from the CTA was used to simulate device deployment, demonstrating successful exclusion of the sinus venosus ASD with return of the RUPV to the left atrium (LA). Post simulation, the 3D model was used for informed consent. The patient was then taken to the hybrid operating room. On-table cone beam CT was performed and registered with the CTA images. This enabled overlay of 3D regions of interest to live 2D fluoroscopy. The stent graft was then deployed using 3D regions of interest for guidance. Hemodynamics and angiography demonstrated successful exclusion of the sinus venosus ASD and unobstructed return of RUPV to the LA. This is the first report of comprehensive use of contemporary imaging for planning, simulation, patient consent, and procedural guidance for patient-centered complex structural intervention in repair of sinus venosus ASD with PAPVR. We propose this as a process model for continued innovation in structural interventions.

Project description:BackgroundBrain abscess is a common complication in children with cyanotic congenital heart disease. The presence of an underlying acyanotic congenital heart disease is usually not suspected in an adult patient presenting with brain abscess.Case summaryA 51-year-old male patient with no known co-morbidities came with complaints of recent onset right lower limb weakness needing support while walking and on evaluation was found to have brain abscess. He underwent robotic endoscope assisted endoport excision of the brain abscess. Two-dimensional transthoracic echocardiography showed right atrial and right ventricular dilatation with mild low-pressure tricuspid regurgitation. Transoesophageal echocardiography (TOE) revealed sinus venosus atrial septal defect (ASD) with left-to-right shunt with the right upper pulmonary vein draining into superior vena cava. Contrast echocardiography revealed a small transient right-to-left shunt. He has been advised to undergo elective surgical closure of ASD with partial anomalous pulmonary venous connection repair.DiscussionRight-to-left shunting in ASDs can occur in the early systole even in the absence of raised pressures in the right side of the heart, even when the predominant shunt is left to right, but the magnitude of such a shunt is small and transient and is easily missed. Contrast echocardiography and TOE should be done as a part of evaluation of patients presenting with brain abscess.

Project description:We present an unusual variant of the sinus venosus defect in which an obvious window is formed between a single pulmonary vein and the superior vena cava, the pulmonary vein retaining its connection to the left atrium. Two patients were operated on via right anterior minithoracotomy. A large single right pulmonary vein was found connecting to the left atrium. There was a large side-to-side communication between the superior vena cava and the pulmonary vein resulting in partially anomalous pulmonary venous drainage. A side-biting clamp was applied in the superior vena cava and the pulmonary vein at both sides of the communication, and the vein was divided. The incision in both veins was closed with a running suture.
