Review Case ReportsTranscatheter closure of a ventricular septal defect resulting from knife stabbing using the Amplatzer muscular VSD occluder.
We report for the first time the transcatheter closure of a traumatic ventricular septal defect (VSD) with the Amplatzer muscular VSD occluder in a 34-year-old man who had been stabbed through the heart. After his initial life-saving surgery to relieve tamponade, control bleeding, and repair the lacerated right ventricle, the risks and difficulties of subsequent open heart surgery were felt to favor transcatheter closure. We review other reports of transcatheter closure of traumatic VSD.

Comparative StudyExperimental efficacy of an everolimus eluting cobalt chromium stent.
Rapamycin and its analogs are now being coated on different stent platforms, using different polymer matrices to prevent restenosis by impairing vascular smooth muscle cell proliferation and neointimal formation. ⋯ Stent-based delivery of sirolimus and everolimus delivered via durable polymeric matrices are equally effective in the suppression of neointimal formation at day 28 in the porcine coronary model. Further study is necessary to document dose response and long-term comparative effects of these drug-eluting stents.

Transcatheter closure of perimembranous ventricular septal defects using amplatzer asymmetric ventricular septal defect occluder: preliminary experience with 18-month follow up.
This study reports our experience in the nonsurgical closure of perimembranous ventricular septal defects in children and adolescents with the Amplatzer asymmetric ventricular septal defect occluder and the outcome of an 18-month follow up. ⋯ In carefully selected children and young adults, the Amplatzer asymmetric ventricular septal defect occluder is a promising device for transcatheter closure of perimembranous ventricular septal defect with encouraging results on short term follow up.

Case ReportsResuscitation and recovery from acute right ventricular failure using a percutaneous right ventricular assist device.
A number of techniques have been proposed for circulatory support in patients with severe right heart failure. We report on a patient with right ventricular (RV) infarction complicated by cardiogenic shock, who was resuscitated by the novel use of a percutaneous right ventricular assist device. ⋯ RV decompression for 3 days was accompanied by recovery of contractile function, and the patient was successfully weaned from the device. Future trials are needed to assess the effectiveness of the percutaneous ventricular assist device in patients with RV failure.

Novel percutaneous catheter thrombectomy in acute massive pulmonary embolism: rotational bidirectional thrombectomy (ROBOT).
Although thrombolysis is a standard therapy in cases of pulmonary embolism (PE), fatal outcome is often observed. We designed and investigated the efficacy of a novel percutaneous catheter therapy, rotational bidirectional thrombectomy (ROBOT), for PE. ⋯ ROBOT therapy results in a significant, rapid improvement in the hemodynamic situation and in a better outcome than conventional therapy in patients with acute massive pulmonary embolism.
