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.

Single versus Dual-Operator Approaches for Percutaneous Coronary Interventions within Chronic Total Occlusion-An Analysis of 27,788 Patients

(1) Background: Since the treatment of chronic total occlusion (CTO) with percutaneous coronary intervention (PCI) is associated with high procedural complexity, it has been suggested to use a multi-operator approach. This study was aimed at evaluating the procedural outcomes of single (SO) versus dual-operator (DO) CTO-PCI approaches. (2) Methods: This retrospective analysis included data from the Polish Registry of Invasive Cardiology Procedures (ORPKI), collected between January 2014 and December 2020. To compare the DO and SO approaches, propensity score matching was introduced with equalized baseline features. (3) Results: The DO approach was applied in 3604 (13%) out of 27,788 CTO-PCI cases. Patients undergoing DO CTO-PCI experienced puncture-site bleeding less often than the SO group (0.1% vs. 0.3%, p = 0.03). No differences were found in the technical success rate (successful revascularization with thrombolysis in myocardial infarction flow grade 2/3) of the SO (72.4%) versus the DO approach (71.2%). Moreover, the presence of either multi-vessel (MVD) or left main coronary artery disease (LMCA) (odds ratio (OR), 1.67 (95% confidence interval (CI), 1.20-2.32); p = 0.002), as well as lower annual and total operator volumes of PCI and CTO-PCI, could be noted as factors linked with the DO approach. (4) Conclusions: Due to the retrospective character, the findings of this study have to be considered only as hypothesis-generating. DO CTO-PCI was infrequent and was performed on patients who were more likely to have LMCA lesions or MVD. Operators collaboratively performing CTO-PCIs were more likely to have less experience. Puncture-site bleeding occurred less often in the dual-operator group; however, second-operator involvement had no impact on the technical success of the intervention.

Performance of digital single-operator cholangiopancreatoscope for biliopancreatic diseases in real life: results from a prospective multicenter study

OBJECTIVES

Peroralcholangio-pancreatoscopy (POCP) is used for diagnosis and treatment of biliopancreatic disease when standard endoscopy (ERCP) or pre-operative imaging workup failed. We aimed to evaluate the diagnostic and therapeutic performance of POCP in complex biliary and pancreatic diseases.

MATERIALS AND METHODS

Patients with indeterminate biliary or pancreatic duct (PD) strictures, and patients with failure of complex biliary or pancreatic stones removal, were enrolled (six centers). The primary endpoint evaluated malignancy diagnostic performances (accuracy, sensitivity, specificity) and therapeutic performances (biliary or pancreatic stones extraction). Secondary endpoints evaluated: technical success in lesion visualization, ease of maneuvering, image quality and 30-days complications.

RESULTS

From November 2016 to March 2018, 66 patients were included: 29/37 women/men, median age (IQR): 73 (64-82). Fifty-three patients had diagnostic POCP and 13 patients therapeutic POCP. One endoscopist with one or two endoscopy nurses performed 94% of the POCP. The 'POCP visual impression' of malignancy showed 92.0% sensitivity, 92.9 % specificity and 92.5 % overall accuracy compared with the final diagnosis. 'POCP-guided samples histological analysis' showed 75.0 % sensitivity and 91.6% specificity. The technical success for lesion visualization was 98.5%. The median VAS scores for insertions in bile and PD were respectively 9.0 (8.1-9.6) and 9.0 (8.8-10.0). Median VAS score for access to the lesion and image quality were respectively 9.0 (7.7-9.6) and 9.0 (7.9-9.7). Only three 30-day minor complications occurred without any major complications.

CONCLUSIONS

POCP was an effective, safe and easy-to-use tool in routine clinical practice for the management of complex diagnostic and therapeutic biliary and pancreatic diseases (NCT03190343).
