We herein describe the previously unreported combination of partial anomalous venous connection to the superior vena cava combined with situs inversus totalis. Following peripheral contrast injection, bubbles appeared initially in the left atrium allowing the diagnosis of a supra-atrial connection to be made using transthoracic echocardiography, but this timing was not anymore reproduced during transesophageal echocardiography performed minutes later. Cardiac computed tomography allowed the final diagnosis to be made...

We present a case of renal infarction in a 43-year-old female with history of stroke at age 14. She was found to be heterozygous for the prothrombin G20210A gene mutation. Loop monitoring revealed no atrial fibrillation. Transthoracic and transesophageal echocardiograms showed no thrombus. However, there was a small shunt due to an atrial septal defect (ASD). She was treated with warfarin and had device closure of her ASD. This was a suspected case of paradoxical embolism through an ASD leading to renal infarction...

Traumatic injuries to the heart contribute significantly to trauma are associated with high mortality. Cardiac gunshot wounds (GSW) are considered more lethal compared to other injuries and present several unique challenges to the anesthesia management and perioperative care. We are reporting a rare case of a trauma victim who survived a GSW to the heart. We will discuss the perioperative care of penetrating cardiac injuries, the role of the anesthesia team in resuscitation, safe anesthesia induction, cardiopulmonary bypass management, and the essential role of intraoperative transesophageal echocardiogram imaging...

The functional aortic annulus offers a clinical approach for the perioperative echocardiographer to classify the mechanisms of aortic regurgitation in acute type-A dissection. Comprehensive examination of the functional aortic annulus in this setting using transesophageal echocardiography can guide surgical therapy for the aortic root by considering the following important aspects: severity and mechanism of aortic regurgitation, extent of root dissection, and the pattern of coronary artery involvement. The final choice of surgical therapy also should take into account factors, such as patient presentation and surgical experience, to limit mortality and morbidity from this challenging acute aortic syndrome...

Background and study aims  Tumor seeding after endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is rare. A 53-year-old man underwent transesophageal EUS-FNA for diagnosis of a 6-cm mass in the mediastinum as seen by computed tomography (CT). Four weeks later, repeat CT scan revealed a mass in the esophageal wall. Upper gastrointestinal endoscopy confirmed a lesion in the mid-esophagus, which was biopsied and found to be consistent with needle tract seeding after EUS-FNA. Tumor seeding in the gastrointestinal wall or peritoneum after EUS-FNA is rare, but may adversely affect the prognosis...

An 80-year-old man presented with a right side lung tumor. The tumor was not abutting the bronchus or chest wall; thus, endobronchial ultrasound (EBUS) and CT-guided biopsy were considered to be technically difficult. We therefore attempted endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). Although the nodule was not abutting the esophagus on CT, an irregularly shaped hypoechoic lesion was visualized on EUS. EUS-FNA was successfully performed. The tumor was diagnosed as squamous cell carcinoma...

Percutaneous closure of an atrial septal defect (ASD) has emerged as an alternative to surgery. A 54-yearold woman with a history of percutaneous ASD closure with a 30-mm Cardia Ultrasept septal occluder (Cardia Inc., Eagan, MN, USA) comprising 2 discs made of Nitinol wire mesh covered with polyvinyl alcohol (PVA) membrane, was admitted to the hospital with unstable angina pectoris. In a routine examination, transthoracic echocardiography revealed a left-to-right shunt through the device. Transesophageal echocardiography (TEE) also demonstrated significant left-to-right shunt through the central portion of the prosthesis...

Percutaneous closure of an atrial septal defect in the cardiac catheterization laboratory requires noninvasive imaging to assist in characterization of the atrial septal defect and deployment of the device. Transesophageal echocardiography is the modality most often used in these circumstances. Transesophageal echocardiographic guidelines exist for the assessment and guidance for atrial septal defect closures, but these guidelines do not mention transgastric views. In this case, we demonstrate that transgastric views are helpful in describing the atrial septal defect, especially as it concerns the inferior vena cava rim...

Left atrial appendage (LAA) closure prevents thromboembolic risk and avoids lifelong anticoagulation due to atrial fibrillation (AF). Nowadays, AtriClip, a modern epicardial device approved in June 2010, allows external and safe closure of LAA in patients undergoing cardiac surgery during other open-chest cardiac surgical procedures. Such a surgical approach and its epicardial deployment differentiates LAA closure with AtriClip from percutaneous closure techniques such as Watchman (Boston Scientific, Marlborough, MA, USA), Lariat (SentreHEART Inc...

Transcatheter closure of atrial septal defects and patent foramen ovale has become increasingly common with advances in device and imaging technology. The percutaneous approach is now the preferred method of closure when anatomically suitable. Two-dimensional and 3-dimensional echocardiography determines anatomic suitability by characterizing the interatrial defect and its surrounding structures, and is critical for intraprocedural guidance and postprocedure follow-up. This article provides an overview of interatrial anatomy as it pertains to interventional considerations and discusses the transthoracic, transesophageal, and intracardiac echocardiographic modalities used for periprocedural and intraprocedural imaging of the interatrial septum...

Once deemed benign, patent foramen ovale (PFO)-mediated right-to-left shunting has now been linked to stroke, migraine, and hypoxemia. Contrast transesophageal echocardiography is considered the standard technique for identifying a PFO, allowing visualization of the atrial septal anatomy and differentiation from non-PFO right-to-left shunts. Transthoracic echocardiography is the most common method for PFO imaging, being cost-effective, but has the lowest sensitivity. Transcranial Doppler is highly sensitive but is unable to differentiate cardiac from pulmonary shunts; it is the best method to quantitate shunt severity, being more sensitive than transthoracic or transesophageal echocardiography so is our preferred screening method for PFO...

Background and purpose Previous studies have suggested that atrial septal aneurysm is a potential risk factor for cerebral embolism. However, the association between the level of atrial septal protrusion and cerebral embolism is still unclear. The purpose of the present study was to assess the association between the maximal distance of atrial septal protrusion and cryptogenic stroke. Methods A total of 588 consecutive acute ischemic stroke patients (70 ± 11 (mean ± SD) years, 401 men) who underwent transesophageal echocardiography were enrolled...

Invasion of a renal cell carcinoma thrombus into the inferior vena cava and right atrium is infrequent. Reaching and completely excising a tumor from the inferior vena cava is particularly challenging because the liver covers the surgical field. We report the case of a 61-year-old man who underwent surgery for a renal cell carcinoma of the right kidney that extended into the inferior vena cava and right atrium. During dissection of the liver to expose the inferior vena cava, transesophageal echocardiograms revealed right atrial mass migration into the tricuspid valve...

INTRODUCTION: Left atrial appendage (LAA) closure with the WATCHMAN device, according to FDA labelling, is recommended in patients with a maximal LAA ostial width between 17-31 mm. The safety and efficacy of LAA closure in patients with a maximal LAA ostial width < 17 mm has not been evaluated. The goal of this study was to determine the acute and short-term safety and efficacy of LAA closure with the WATCHMAN device in patients with a maximal LAA ostial width < 17 mm. METHODS AND RESULTS: Thirty-two consecutive patients with a maximal LAA ostial width < 17 mm as determined by a screening transesophageal echocardiogram (TEE) underwent LAA closure with the WATCHMAN device between March 2015 and November 2016 at five medical centers, and were included in this study...
