Usefulness of intracardiac echocardiography with a mechanical probe for catheter-based interventions: a 10-year prospective registry.

Background: The clinical outcome benefit of intracardiac echocardiography (ICE) with a mechanical probe during congenital heart disease interventions has not been fully investigated. We reported the long-term results of a prospective registry of interatrial shunt closure guided by mechanical ICE.

Methods: We enrolled 537 patients (mean age 48 ± 19.

Manual versus nonmanual thrombectomy in primary and rescue percutaneous coronary angioplasty.

Although many thrombectomy devices have been tested in ST-segment elevation acute myocardial infarction (STEMI), there are no comparative data on safety or effectiveness in thrombectomy or ST-segment resolution. This study compares manual versus nonmanual thrombectomy devices in patients undergoing primary or rescue percutaneous coronary intervention in a tertiary care center. We identified 232 consecutive patients with STEMI and time from symptom onset to emergency room contact of < or = 12 h undergoing percutaneous coronary intervention with coronary thrombectomy devices.

[Manual thrombus aspiration with the Export catheter during primary and rescue angioplasty. Predictors of failed myocardial reperfusion].

Background: Manual thrombus aspiration seems to improve myocardial reperfusion after coronary angioplasty in patients with ST-elevation acute coronary syndrome. We sought to assess the independent variables of complete myocardial reperfusion after primary and rescue coronary angioplasty with use of the Export manual thrombus aspiration catheter.

Methods: Myocardial reperfusion were judged complete if ST-segment resolution were >70% at 60 min post-procedure ECG.
