Meta Analysis
Meta-Analysis of Intraocular Bleeding With Dual Antiplatelet Therapy Using P2Y12 Inhibitors Prasugrel or Ticagrelor.
Intraocular bleeding is a devastating clinical event due to its potentially blinding nature. It is not known if determine if dual antiplatelet therapy using aspirin and potent P2Y12 inhibitors increases this risk. We searched MEDLINE and ClinicalTrials.gov for randomized controlled trials that were phase III, randomly assigned patients to dual antiplatelet therapy with either aspirin and a potent P2Y12 inhibitor or aspirin and clopidogrel, had follow-up of 6 months, and at least 200 patients. ⋯ The use of random-effects meta-analysis did not change the effect estimate or confidence intervals, and the results appeared similar when stratified by potent P2Y12 inhibitor (p = 0.97). In conclusion, this collaborative meta-analysis of dual antiplatelet trials does not suggest that the risk of intraocular bleeding is increased with the use of potent P2Y12 inhibitors compared with clopidogrel. Our results suggest that these potent P2Y12 inhibitors may continue to be used cautiously where indicated as part of dual antiplatelet therapy, even in those at high risk of spontaneous intraocular bleeding.

This study aimed to investigate the rate of severe structural valve deterioration (SVD) and long-term outcomes of patients with severe symptomatic aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR). Propensity score matched analysis of patients who underwent TAVI (n = 216) and SAVR (n = 216) between 2008 and 2012. Long-term echocardiographic parameters and clinical outcomes were assessed after more than 6 years after TAVI/SAVR. ⋯ Rate of moderate or severe aortic regurgitation was significantly higher in the TAVI group with predominant use of first-generation valves. Reintervention rate was low in both groups. Survival rate was lower after TAVI, probably because of higher frailty index, but incidence of cardiovascular events, PPI, and SVD was similar in both groups.

Impact of Malnutrition on Outcomes Following Transcatheter Aortic Valve Implantation (from a National Cohort).
Malnutrition is associated with increased mortality in open cardiac surgery, but its impact on transcatheter aortic valve implantation (TAVI) is unknown. This study utilized the National Readmissions Database to evaluate the impact of malnutrition on mortality, complications, length of stay (LOS), 30-day readmission, and total charges following TAVI. Adult patients undergoing isolated TAVI for severe aortic stenosis were identified using the 2011 to 2016 National Readmissions Database, which accounts for 56.6% of all US hospitalizations. ⋯ Malnutrition was most significantly associated with infectious complications at index hospitalization (AOR = 3.88, p <0.001) and at 30-day readmission (AOR = 1.43, p <0.027). In conclusion, malnutrition is independently associated with increased mortality, complications, readmission, and resource utilization in patients undergoing TAVI. Preoperative risk stratification and malnutrition modification may improve outcomes in this vulnerable population.

Efficiency, Safety, and Quality of Life After Transcatheter Aortic Valve Implantation Performed With Moderate Sedation Versus General Anesthesia.
There is growing interest in "minimalist" transcatheter aortic valve implantation (M-TAVI), performed with conscious sedation instead of general anesthesia (GA-TAVI). We assessed the impact of M-TAVI on procedural efficiency, long-term safety, and quality of life (QoL) in 477 patients with severe aortic stenosis (82 years, women 50%, STS 5.0), who underwent M-TAVI (n = 278) or GA-TAVI (n = 199). M-TAVI patients were less likely to have NYHA Class ≥3, valve-in-valve TAVI, and receive self-expanding valves. ⋯ QoL scores were similar at baseline and 1-month after TAVI. In multivariable analyses, M-TAVI showed significant improvements in all parameters of procedural efficiency. In conclusion, M-TAVI is more efficient than GA-TAVI, with similar safety at 1-month and long-term, and similar QoL scores at 1 month.
