Review Meta AnalysisMortality Not Correlated With Paclitaxel Exposure: An Independent Patient-Level Meta-Analysis of a Drug-Coated Balloon.
Five years of prospective clinical trials confirm that the paclitaxel drug-coated balloon (DCB) (IN.PACT Admiral, Medtronic, Dublin, Ireland) is safe and effective to treat femoropopliteal artery disease. A recent meta-analysis of heterogeneous trials of paclitaxel-based balloons and stents reported that they are associated with increased mortality and that higher doses are linked to higher mortality from 2 to 5 years. ⋯ This independent patient-level meta-analysis demonstrates that this paclitaxel DCB is safe. Within DCB patients, there was no correlation between level of paclitaxel exposure and mortality. (Randomized Trial of IN.PACT Admiral® Drug Coated Balloon vs Standard PTA for the Treatment of SFA and Proximal Popliteal Arterial Disease [INPACT SFA I], NCT01175850; IN.PACT Admiral Drug-Coated Balloon vs. Standard Balloon Angioplasty for the Treatment of Superficial Femoral Artery [SFA] and Proximal Popliteal Artery [PPA] [INPACT SFA II], NCT01566461; MDT-2113 Drug-Eluting Balloon vs. Standard PTA for the Treatment of Atherosclerotic Lesions in the Superficial Femoral Artery and/or Proximal Popliteal Artery [MDT-2113 SFA], NCT01947478; The IN.PACT SFA Clinical Study for the Treatment of Atherosclerotic Lesions in the Superficial Femoral Artery and/or Proximal Popliteal Artery Using the IN.PACT Admiral™ Drug-Eluting Balloon in a Chinese Patient Population, NCT02118532; and IN.PACT Global Clinical Study, NCT01609296).

Observational StudyTitration of Medical Therapy for Heart Failure With Reduced Ejection Fraction.
Guidelines recommend that patients with heart failure with reduced ejection fraction (HFrEF) have medical therapy titrated to target doses derived from clinical trials, as tolerated. The degree to which titration occurs in contemporary U.S. practice is unknown. ⋯ In this contemporary U.S. registry, most eligible HFrEF patients did not receive target doses of medical therapy at any point during follow-up, and few patients had doses increased over time. Although most patients had no alterations in medical therapy, multiple clinical factors were independently associated with medication changes. Further quality improvement efforts are urgently needed to improve guideline-directed medication titration for HFrEF.

Comparative StudyMaternal Comorbidities and Complications of Delivery in Pregnant Women With Congenital Heart Disease.
Pregnant women with congenital heart defects (CHDs) may be at increased risk for adverse events during delivery. ⋯ Pregnant women with CHDs were more likely to have comorbidities and experience adverse events during delivery. These women require additional monitoring and care.

Randomized Controlled Trial Comparative StudyContemporary Outcomes Following Coronary Artery Bypass Graft Surgery for Left Main Disease.
Although results of percutaneous coronary intervention (PCI) have been steadily improving, whether surgical outcomes have improved over time is not fully elucidated. ⋯ Over a 5- to 7-year period, significant improvement in event-free survival after surgical revascularization for LM disease at 3 years was noted between the SYNTAX and EXCEL trials, consistent with improving results with cardiac surgery over time. (Synergy Between PCI With Taxus and Cardiac Surgery [SYNTAX]; NCT00114972; Evaluation of XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization [EXCEL]; NCT01205776).

Percutaneous Coronary Intervention in Older Patients With ST-Segment Elevation Myocardial Infarction and Cardiogenic Shock.
Older adults ≥75 years of age carry an increased risk of mortality after ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock. ⋯ This large and contemporary analysis shows that utilization of PCI in older adults with STEMI and cardiogenic shock is increasing and paralleled by a substantial reduction in mortality. Although clinical judgment is critical, older adults should not be excluded from early revascularization based on age in the absence of absolute contraindications.
