RESUMO

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.

RESUMO

Conventional venoarterial extracorporeal membrane oxygenation (VA-ECMO) places a functional afterload burden on the left ventricle. In the setting of acute severe aortic insufficiency-induced cardiogenic shock, the utility of VA-ECMO in combination with a failing valve may result in catastrophic haemodynamic consequences. This challenge is compounded when the culprit is a failing surgical bioprosthetic valve. We present a case of severe rapid-onset bioprosthetic aortic insufficiency-induced cardiogenic shock successfully resuscitated with left atrial VA-ECMO promptly followed by emergent percutaneous valve-in-valve transaortic valve replacement. We discuss the logistics, implications, and associated haemodynamic manifestations in utilizing this strategy for such disease processes.

RESUMO

The AngioVac© system (AngioDynamics, Latham, NY, USA) is a percutaneous catheter-based approach indicated for the removal of unwanted intravascular material from venous circulation and offers a safe alternative to conventional surgical extraction. This series describes various pathologies that were high risk for surgical management in which AngioVac© proved to be a suitable alternative. Learning objectives: Demonstrate the utility of minimally invasive techniques for removal of unwanted venous material using percutaneous endovascular vacuum assisted aspiration. Formulate a new treatment algorithm in the management of unwanted right-sided material.

RESUMO

Background: Contemporary procedural guidelines for percutaneous left atrial appendage occlusions (LAAO) with the WATCHMAN device often require the utilization of pre-screening imaging, general anaesthesia, intubation, a dedicated intra-procedural echocardiographer, and overnight observation. For these reasons, LAAO with the WATCHMAN is not economically feasible for many hospital systems. Thus, we sought to evaluate a newstrategy for implantation that may provide a more minimalistic and less cumbersome approach to LAAO. Case summary: We describe five cases utilizing single-operator left atrial appendage occlusion utilizing conscious sedation, transoesophageal echocardiography, lack of outpatient pre-imaging, and same-day expedited discharge (SOLO-CLOSE)-a novel single-operator procedural strategy for LAAO that safely foregoes the aforementioned procedural requirements and allows for same-day early discharge. All five patients were observed according to our newly devised SOLO-CLOSE protocol and were safely discharged home the same day. Follow-up transoesophageal echocardiography (TEE) at 45 days and 1 year revealed well-seated and well-anchored devices with no leaks (<5 mm) or device-related thrombi. Discussion: The SOLO-CLOSE series is the first ever documented WATCHMAN strategy that utilizes a single-operator, TEE-guided, nurse-driven conscious sedation protocol that defers pre-screening imaging and allows for same-day discharge. The versatility of this technique allows proceduralists to comfortably achieve successful LAAO despite a wide range of risk profiles. This single-operator technique has potential to become a widely accepted universal approach for non-pharmacological cardioembolic stroke prophylaxis due to its efficacy, safety, simplicity, and presumable cost-effectiveness.

RESUMO

Transcatheter mitral valve replacement represents an innovative interventional technique for implanting a new mitral prosthesis without surgery. Although technical success is high, post-procedural issues and complications may occur. This report emphasizes the importance of considering alternative cardiac pathologies that may be seen post valvular interventions. (Level of Difficulty: Beginner.).
