Background and Purpose: Transradial percutaneous coronary intervention (TR-PCI) has been increasingly popular over the last decade in the US. Previous studies have shown that same-day (SD) discharge after elective PCI is as safe as overnight (ON) observation. Our study was performed to assess the clinical and financial impact of early discharge in patients undergoing TR-PCI.Methods: This is a single center registry of patients undergoing elective TR-PCI. Timing of discharge was determined by the treating physician. (Groups: Same Day Discharge -SD-; Overnight Stay -ON-). Demographic data, procedural characteristics and adverse outcomes were recorded. Outcomes included 30 day-MACE and procedure- related complications, as well as total operative costs in patients from both groups. Propensity score matching for patient demographics, coronary symptoms and procedure indicators was used to compare both groups.Results: The entire cohort included 852 patients (429 in SD group and 423 in ON group) and the propensity score matched groups of 245 patients in the SD group and 245 patients in the ON group. The two groups had no significant baseline clinical differences, and had similar clinical outcomes. Specifically, no significant difference was noted in procedural complications (3.7% vs 2.5%, p = 0.43), re-hospitalization (4.1% vs 4.1%, p = 0.92), re-intervention (2.5% vs 2.1%, p = 0.77), myocardial infarction (0% vs 0.08%, p = 0.15), stroke (0% vs 0%, p = 1.0) and all-cause mortality (0% vs 0%, p = 1.0). SD Group patients had a significant lower procedure-related cost compared to overnight stay patients ($3,346.45 vs $4,681.99, p < 0.0001) and lower 30-day post procedure-associated cumulative costs/total operating costs ($4,493.22 vs $7,112.21, p < 0.0001).Conclusion: In elective patients undergoing low risk TR-PCI, same-day discharge seems to be a safe and feasible clinical practice, with significant potential savings to the US healthcare system.

Background: Long-term patency rates for percutaneous peripheral arterial interventions are suboptimal. Optical coherence tomography (OCT) guided atherectomy may yield superior patency by optimizing plaque removal while preserving the tunica media and adventitia.Methods: The VISION study is a multicenter prospective study of patients with peripheral arterial disease undergoing OCT guided atherectomy with the Pantheris™ device. In 11 patients enrolled in a single center, we report procedural and clinical outcomes, at 30days and 6months.Results: The mean age was 63±11years and 73% (n=8) were men. The target lesion was in the superficial femoral artery in 82% (n=9) of the patients. Mean stenosis severity was 87%±10% and mean lesion length was 39±31mm. Procedural success was observed in all patients with no device related complications. Mean post-atherectomy stenosis was 18%±15%. Almost all excised tissue consisted of intimal plaque (94%). At 30days, significant improvements in Rutherford class, VascuQoL scores and ABI were observed, 0.9±0.8 vs. 3.1±0.7 (p=0.01), 4.9±1.9 vs. 3.6±1.5 (p=0.03) and 1.04±0.19 vs. 0.80±0.19 (p<0.01) respectively. At 6months, there were significant improvements in Rutherford class (1.0±1.0 vs. 3.1±0.7, p=0.01) and ABI (0.93±0.19 versus 0.80±0.19, p=0.02) but not in VascuQoL scores (3.7±1.4 versus 3.6±1.5, p=0.48). Target lesion revascularization occurred in 18% (n=2) of the patients.Conclusion: OCT guided atherectomy resulted in high procedural success, no device related complications and encouraging results up to 6months. Histological analysis suggested little injury to the media and adventitia. Larger studies are needed to confirm the efficacy of this approach. [ABSTRACT FROM AUTHOR]
