Starfix lead extraction: Clinical experience and technical issues

AbstractTransvenous lead extraction (TLE) of the Starfix coronary sinus (CS) active-fixation lead may be challenging, due to undeployment of fixation lobes and venous occlusion. We report our experience in Starfix TLE, in comparison with previous data.A 78-year-old male, implanted in 2009 with Starfix lead, was referred to our institution for TLE, due to infective endocarditis with lead-associated vegetations. The tip of Starfix lead was located in distant, anterior position, in the great cardiac vein, close to patent left internal mammary artery-to-left anterior descending artery anastomosis, and first-choice surgical removal had a prohibitive operative risk.Conventional dilatation beyond CS ostium, as well as the use of a standard delivery catheter, was ineffective. An off-label modification of the delivery, by cutting the distal soft tip, was successful. However, the tip of the lead fragmented and was trapped in the innominate vein. Then a gooseneck snare grasped the fragment, allowing complete retrieval.TLE of Starfix leads may be particularly challenging, especially when its tip is located in a distant anterior location. In these cases, important help may be obtained by dilatation within the CS, by means of conventional or modified delivery catheters. Only experienced operators, sometimes with non-conventional techniques, should perform TLE of Starfix leads.<Learning objective: TLE of Starfix leads may be challenging, particularly when the tip is located in a distant anterior position. Dilatation with conventional tools may be precluded. In these cases modifications of the delivery catheters may be useful. Surgery should be avoided as first-choice procedure; only experienced operators, sometimes with non-conventional techniques, should perform TLE of Starfix leads.

Sixty-day readmission rate after percutaneous coronary intervention: predictors and impact on long-term outcomes

Thirty-day readmission rate after percutaneous coronary intervention (PCI) is used as an index of quality of care, but the complete recovery from any myocardial damage needs 8 weeks. We evaluated the readmission rate 60 days after PCI, defined its predictors, and investigated its relationship with long-term prognosis

Short term outcome following acute phase switch among P2Y12 inhibitors in patients presenting with acute coronary syndrome treated with PCI: A systematic review and meta-analysis including 22,500 patients from 14 studies

Introduction: The efficacy and safety of switching P2Y12 receptor antagonists in patients admitted for acute coronary syndrome (ACS) remain unclear. We assessed the short-term clinical outcomes (in-hospital and within 30 days) of switching P2Y12 inhibitor (P2Y12I) drugs versus maintaining the same regimen by performing a comprehensive review and meta-analysis of available data. Methods: MEDLINE/PubMed/SCOPUS/Cochrane databases were screened for studies regarding switching of P2Y12I in patients with ACS that reported 30 days follow-up. Major cardiac events (MACE) and bleeding were compared between patients who were switched/not switched. Results: 22,500 patients from 14 studies were included. Unstable angina/non-ST elevation myocardial infarction (62.0%, interquartile range, 52.8%–68.0%) was the most common clinical presentation. The total number switched was 4294 (19.1%); escalation in 3416 (79.5%) patients (from clopidogrel to prasugrel, 62.9%) and de-escalation in 18.5%. Pooled analysis revealed no significant differences in MACE for any comparison; risk of bleeding was significantly increased among switched patients overall (odds ratio [OR], 1.60; 95% confidence interval [CI] 1.22–2.10) and increased in the escalation group (OR, 1.51; 95% CI, 1.06–2.16). Conclusions: Among patients presenting with ACS, switching from one P2Y12I agent to another in the acute phase seems associated with a short-term increased risk of bleeding. Accurate upfront selection and prescription of a P2Y12I based on ischemic and bleeding risks is paramount to avoid adverse events switching-related during hospitalization and in the first 30 days.
