OBJECTIVE: Percutaneous mitral valve repair with the MitraClip system is an alternative procedure for high-risk patients not suitable for conventional surgery. The MitraClip can be safely performed under general anesthesia (GA) or deep sedation (DS) with spontaneous breathing using a combination of propofol and remifentanil. This study aimed to evaluate the benefits of target-controlled infusion (TCI) of remifentanil and administration of propofol during DS compared with manual administration of total intravenous anesthesia (TIVA) medication during GA in patients undergoing MitraClip. We assessed the impact of these procedures in terms of remifentanil dose, hemodynamic profile, adverse events, and days of hospital stay after the process. PATIENTS AND METHODS: From March 2013 to June 2015 (mean age 73.5 ± 9,54), patients underwent transcatheter MitraClip repair, 27 received DS via TCI and 27 GA with TIVA. RESULTS: Acute procedural success was 100%. DS-TCI group, in addition to a significant reduction of remifentanil dose administrated (249 μg vs. 2865, p < 0.01), resulted in a decrease in vasopressor drugs requirement for hemodynamic adjustments (29.6% vs. 63%, p = 0.03) during the procedure and a reduction of hypotension (p = 0.08). The duration of postoperative hospitalization did not differ between the two groups (5.4 days vs. 5.8 days, p = 0.4). CONCLUSIONS: Administration of remifentanil by TCI for DS in spontaneously breathing patients offers stable anesthesia conditions, with a lower amount of drugs, higher hemodynamic stability, and decreased side effects.

OBJECTIVE: Spontaneous coronary artery dissection (SCAD) is a spontaneous separation of the coronary artery wall whose etiology appears to be poorly understood. SCAD is a rare cause of acute coronary syndromes, and it is a life-threatening condition. CASE REPORT: We report the case of a young woman who developed SCAD during a thyroid storm (TS). RESULTS: To the best of our knowledge, this is the first reported case of SCAD during a TS, and it suggests a possible association between high levels of circulating thyroid hormones and SCAD susceptibility. CONCLUSIONS: Early identification of SCAD predisposing factors is important to identify highrisk patients. In patients presenting to the emergency department because of chest pain with a history of dysthyroidism, early determination of thyroid hormones and troponin could prevent certain forms of sudden cardiac death.

OBJECTIVE: We studied the impact of transcatheter aortic valve implantation (TAVI) compared to the surgical aortic valve replacement (SAVR) on 30-day and one-year mortality from randomized controlled trials (RCTs) in patients with severe aortic stenosis at high or low-intermediate surgical risk. MATERIALS AND METHODS: All RCTs were retrieved through PubMed computerized database and the site https://www.clinicaltrials.gov from January 2010 until March 31st, 2019. The absolute risk reduction (RD) with the 95% confidence interval (CI) was used to assess the effectiveness of the intervention under comparison. We evaluated overall mortality rates at 30-day and one-year follow-up in the comparison between TAVI vs. SAVR. We also evaluated the role played by the site access for TAVI performed through the femoral or subclavian artery (TV-TAVI) vs. SAVR, or transapically (TA-TAVI) vs. SAVR. RESULTS: In the "as-treated population" the overall 30-day mortality was significantly lower in TAVI (p=0.03) with respect to SAVR. However, the analysis for TAVI subgroups showed that 30-day mortality was (1) significantly lower in TV-TAVI vs. SAVR (p=0.006), (2) increased, not significantly, in TA-TAVI vs. SAVR (p=0.62). No significant differences were found between TAVI vs. SAVR at one-year follow-up. CONCLUSIONS: The results of our meta-analysis suggest that TV-TAVI is a powerful tool in the treatment of severe aortic stenosis at high or low-intermediate surgical risk, with a significant lower mortality with respect to SAVR. On the contrary, SAVR seems to provide better results than TA-TAVI. [ABSTRACT FROM AUTHOR]
