Femoral artery hemostasis using an implantable device (Angio-Seal) after coronary angioplasty.

Coronary catheter interventional procedures are associated with risk of access site complications. We report our experience with Angio-Seal, an implantable hemostasis device, when used in the femoral artery after coronary angioplasty procedures. Sixty-eight patients were studied.

Rapid arterial hemostasis and decreased access site complications after cardiac catheterization and angioplasty: results of a randomized trial of a novel hemostatic device.

Objectives: This study was performed to test the safety and efficacy of a novel bioabsorbable hemostatic puncture closure device deployed through an arterial sheath.

Background: Cardiac catheterization procedures are associated with a risk of complications at the arterial access site. Increasing numbers of interventional procedures requiring large sheaths or intense anticoagulation underline the need for secure, rapid methods of obtaining hemostasis at the time of sheath removal.

Immediate arterial hemostasis after cardiac catheterization: initial experience with a new puncture closure device.

A novel device for obtaining arterial hemostasis after invasive procedures was tested in 30 patients undergoing diagnostic catheterization (26 patients) or coronary angioplasty (4 patients). The device is deployed through an arterial sheath and forms a positive mechanical seal both inside and outside the defect in the arterial wall. The components are all bioabsorbable.

Adrenergically mediated variations in the energy required to defibrillate the heart: observations in closed-chest, nonanesthetized dogs.

The day-to-day variations in epicardial defibrillation threshold (DFT) were examined in closed-chest, unanesthetized dogs. In 11 animals, DFT decreased from 15.8 +/- 2.

Cardiac operations in patients over 80 years of age.

Twenty-five patients between 80 and 89 years of age underwent a variety of cardiac surgical procedures. Operative mortality was 4%. Perioperative complications were frequent and resulted in an increased hospital stay postoperatively (mean 19.
