ABSTRACT
Peripheral extracorporeal membrane oxygenation (ECMO) is one of the most common strategies for cardiogenic shock. ECMO cannulation is associated with an increased risk of complications. We describe a minimally invasive, off-pump technique to provide adequate hemodynamic support and left ventricular unloading. A 54-year-old male with nonischemic cardiomyopathy and severe peripheral vascular disease with cardiogenic shock was initially supported with inotropes and an intra-aortic balloon pump. Despite continued support, he continued to deteriorate, and we escalated to a temporary left ventricular support with a CentriMag, using a transapical ProtekDuo Rapid Deployment cannula via mini left-thoracotomy. This approach provides adequate hemodynamic support, left ventricular unloading and early ambulation. After 9 days, the patient's functional status was improved and was medically optimized. The patient received a left ventricular assist device as destination therapy. He was discharged home, resumed his normal activities and has been doing well for more than 27 months.
ABSTRACT
Due to the proportionally high mortality rates associated with isolated tricuspid valve surgery, the invasive treatment of such pathology, historically, has been left largely unaddressed. Recently, there has been an appreciation for the mortality and morbidity of tricuspid valve disease, giving rise to the movement towards identifying less invasive, transcatheter approaches for treatment. Due to the technical complexity of these procedures along with the uniqueness and variability of tricuspid valve anatomy, a better appreciation of the tricuspid valve anatomy and pathology is required for pre-procedural planning. While two-dimensional echocardiography serves as the initial non-invasive modality for tricuspid valve evaluation, three-dimensional echocardiography provides a complete en face view of the tricuspid valve and surrounding structures, as well contributes further information regarding disease etiology and severity. In this review, we discuss the utility of three-dimensional echocardiography as a supplement to two-dimensional imaging to better assess tricuspid valve disease and anatomy to aide in future innovative therapies.

INTRODUCTION: Sclerosing Angiomatoid Nodular Transformation of the spleen (SANT) is a rare benign vascular lesion of the spleen with extensive sclerosis and unknown etiology. PRESENTATION OF CASE: We report a new case of SANT of the spleen found in a 53-year-old female following detection of a splenic mass on a routine computed tomography (CT). The patient underwent an uncomplicated laparoscopic splenectomy and the specimen was sent for histopathologic examination. DISCUSSION: A review of the 97 reported cases of SANT found in the literature was undertaken. There were 43 males and 54 females with a median age of 46 years (range: 11-82 years). SANT is classically considered to be a female predominant disease, however 44.3% of reported case were male and the gender predilection may soon be neutralized as more cases are reported. 65 of the 97 (67%) patients were in 30-60 year age group. The majority of lesions (n=50) were incidentally found on imaging, and for those patients presenting with symptoms, abdominal pain (n=18) was the predominant symptom. CONCLUSION: The diagnosis of SANT should be considered in any patient presenting with a splenic lesion that contains an angiomatoid or inflammatory component. As the differential diagnosis for SANT includes malignant pathologies, and currently no reliable diagnostic radiological feature has been identified to differentiate between these conditions, SANT will continue to be diagnosed on the basis of surgical histopathology.
