RESUMO
Passage failure of guidewire is still remained most common reason for percutaneous coronary intervention (PCI) failure in chronic total occlusion (CTO). Intravascular ultrasound study (IVUS) and cardiac CT angiography can help identify features that most influence current success rates of PCI. We report our experience using the reverse controlled antegrade and retrograde subintimal tracking technique under the aid of IVUS, cardiac CT angiography for an ambiguous CTO of proximal right coronary artery.

Below the knee (BTK) interventions are increasing in patients with rest pain or critical limb ischemia, and these interventions are frequently successful in facilitating limb salvage. New intervention techniques and devices allow successful recanalization of occluded BTK arteries. Here, we report a case of successful recanalization of BTK arteries using multidisciplinary methods, including an antegrade approach and retrograde approach without the use of a sheath, but with simple balloon angioplasty, and plaque excision using Silverhawk atherectomy device.

A 42-year-old male patient presented with refractory hypertension and congestive heart failure. He had taken hydrochlorthiazide 50 mg, carvedilol 25 mg, diltiazem 180 mg, and losartan 100 mg per day. Aortogram revealed a severe luminal narrowing in the distal thoracic aorta with a peak systolic pressure gradient of 60 mmHg across the lesion. Endovascular management was performed with 22 x 80 mm self-expandable Nitinol-S stent after predilation with 10 x 40 mm balloon. After endovascular management, the patient's blood pressure, left ventricular ejection fraction (LVEF) and dilated LV dimension were remarkably improved.
