RESUMEN
BACKGROUND: With the advances in percutaneous treatment technologies, the left atrial appendage occlusion (LAAO) and the transcatheter mitral valve repair using MitraClip (TMVR) are increasingly being performed today. The SAFARI 2™ guidewire is primarily used during transcatheter aortic valve implantation (TAVI), our group has also been using it during MitraClip and LAAO procedures. Our clinical study aimed to share our data on the safety and effectiveness for the use of the SAFARI 2™ guidewire during MitraClip or LAAO procedures. METHODS: This study included a total of 1730 patients (948 patients of MitraClip and 782 of LAAO). It was designed as single arm, retrospective, and multicenter between July 2016 and August 2022. SAFARI 2™ guidewire was used exclusively during all the procedures. RESULTS: A total of 1730 patients (male 55.8 %) were included in the study. There was no guidewire-related complications, stroke/transient ischemic attack, bleeding (minor/major/life-threatening), need for cardiac surgery, pneumonia, and vascular dissection/rupture in patients undergoing LAAO. There were 2 device-related pericardial effusions without tamponade. No stroke/transient ischemic attack, bleeding (minor/major/life-threatening), mortality, need for cardiac surgery, pneumonia, guidewire-related complication, pericardial effusion, vascular dissection/rupture, or clip embolization was observed in patients undergoing MitraClip. CONCLUSIONS: By taking advantage of its pre-shaped structure, the SAFARI 2™ guidewire seems to offer a reliable and safe device delivery for both MitraClip and LAAO procedures as a regular work horse wire. Our results should be confirmed by larger randomized or prospective trials.

ABSTRACT Background: Low-grade inflammation is known to facilitate the development of hypertensive organ damage. The systemic immune-inflammation index (SII) is a new inflammatory index based on circulating immune-inflammatory cells. Objectives: The objectives of this study were to investigate the relationship between the SII and asymptomatic organ damage (AOD) in patients with newly diagnosed treatment-naive hypertension (HTN). Methods: A total of 500 participants (≥ 18 years) were enrolled in the study, including 250 patients and 250 healthy volunteers. Microalbuminuria of > 30 mg/day or proteinuria of > 150 mg/day, left ventricular mass index of > 95 g/m2 in women and > 115 g/m2 in men, and carotid intima-media thickness of > 0.9 mm or the presence of plaque in the carotid were evaluated as AOD indicators. AOD grade was classified as follows: Grade I - One organ involved, Grade II - Two organs involved, Grade III - Three organs involved, and Grade IV - Four organs involved. Results: SII values were higher among patients with HTN than in the control group. Positive correlations were found between the SII and AOD indicators and C-reactive protein levels. Increasing SII values were a common independent predictor of the presence and severity of AOD. The gradually increasing threshold values of the SII from no AOD to Grade III-IV exhibited high diagnostic performance. Conclusions: High SII values were independent predictors of the presence and severity of AOD in patients with newly diagnosed treatment-naive HTN. Considering the role of inflammation in HTN, the SII, which can be easily evaluated using blood parameters, can be an effective prognostic screening tool.
