Single-Operator Left atrial appendage Occlusion utilizing Conscious sedation TEE, Lack of Outpatient pre-imaging, and Same-day Expedited discharge (SOLO-CLOSE): A comparison with conventional approach.

BACKGROUND: Left atrial appendage occlusion (LAAO) with WATCHMAN currently requires preprocedural imaging, general anesthesia, and inpatient overnight admission. We sought to facilitate simplification of LAAO. AIMS: We describe and compare SOLO-CLOSE (single-operator LAA occlusion utilizing conscious sedation TEE, lack of outpatient pre-imaging, and same-day expedited discharge) with the conventional approach (CA). METHODS: A single-center retrospective analysis of 163 patients undergoing LAAO between January 2017 and April 2022 was conducted. The SOLO-CLOSE protocol was enacted on December 1, 2020. Before this date, we utilized the CA. The primary efficacy endpoint was defined as successful LAAO with ≤5 mm peri-device leak at time of closure. The primary safety endpoint was the composite incidence of all-cause deaths, any cerebrovascular accident (CVA), device embolization, pericardial effusion, or major postprocedure bleeding within 7 days of the index procedure. Procedure times, 7-day readmission rates, and cost analytics were collected as well. RESULTS: Baseline characteristics were similar in both cohorts. Congestive heart failure (37.5% vs. 11.1%) and malignancy (28.8% vs. 12.5%) were higher in SOLO-CLOSE. Median CHA2D2SVASc score was 5 in both cohorts. The primary efficacy endpoint was met 100% in both cohorts. Primary safety endpoint was similar between cohorts (p = 0.078). Mean procedure time was 30 min shorter in SOLO-CLOSE (p < 0.01). Seven-day readmissions for SOLO-CLOSE was zero. After SOLO-CLOSE implementation, there was a 188% increase in positive contribution margin per case. CONCLUSIONS: The SOLO-CLOSE methodology offers similar efficacy and safety when compared to the CA, while improving clinical efficiency, reducing procedural times, and increasing economic benefit.

Endocarditis of the forgotten valve: vacuum-assisted aspiration (AngioVac) of the eustachian valve: a case report.

Background: Eustachian valve endocarditis (EVE) is a rare entity that traditionally has been treated with antibiotics or surgery, if refractory to antibiotic treatment. Case summary: A 64-year-old man presented with right shoulder pain and new-onset hypoxia. His blood cultures were positive for methicillin-sensitive staphylococcal aureus (MSSA) 1 month ago and he was treated with antibiotics at that time. Blood cultures during this admission were again positive for MSSA. Trans-oesophageal echocardiogram showed a large independently mobile echogenic density consistent with vegetation (3.0 × 1.6 cm) on the eustachian valve (EV). The patient was a poor surgical candidate due to his multiple co-morbidities, and therefore, a non-invasive procedure called AngioVac® was selected. Discussion: In the setting of infective endocarditis refractory to antibiotics, the large-bore percutaneous mechanical aspiration (AngioVac®, AngioDynamics, Latham, NY, USA) system is gaining increasing momentum as the treatment of choice over standard surgical intervention for debulking large vegetations. AngioVac® has provided a minimally invasive and effective measure especially in those unable to tolerate surgery. The novel percutaneous technique is linked to great success in right-sided endocarditis, with the tricuspid valve accounting for a majority of the cases. However, in rare instances, the EV may be involved. To our knowledge, we report the first case of EVE treated with AngioVac®.

To intervene or not to intervene: A case of symptomatic neurocysticercosis complicated by ventriculitis.

Although well described in the current literature, Neurocysticercosis [NCC] remains an enigma when confronted by practitioners. This is in part due to the haphazard nature of the parasitic infection on the central nervous system [CNS]. These include single or multiple anatomic sites of infection, stage of parasitosis, and the resultant inflammatory response. As a result, NCC can present with a complex constellation of symptomatic presentations, making therapeutic regiments highly individualized. Despite intervention, other impediments may arise post-therapy due to the nature of the infection. We present a case of rapidly progressive symptomatic NCC that initially was successfully treated, however would eventually succumb to complications of ventriculitis.
