Pulmonary artery stents in the recent era

Abstract

In conclusion, stent implantation shows excellent immediate and 1-year follow-up results with maintenance of improved caliber of the stented vessel and lowered right ventricular systolic pressures.

Treatment of Peripheral Pulmonary Artery Stenosis

“…[36][37][38] By 2014, with over 20 studies that had tested the efficacy of stent placement for PAS, this treatment method was shown to have an exceptionally high successful dilation rate of 90% on average, with some studies showing a 100% success rate. 10,14,[39][40][41][42] These stents could then significantly improve the PA pressure gradient, RV pressure, and pulmonary perfusion. There is also evidence of hemodynamic success nicely translating to clinical success, measured as improved ventilator efficiency, aerobic capacity, and symptoms.…”

Partially open stent after balloon catheter iatrogenic perforation. How to solve this complication using a novel technique? The Mij-Her technique

“…The other underwent surgical repair. 8 We describe the perforation of a balloon catheter while trying to advance it to the stenotic pulmonary branch, which was caused while cutting the balloon protective covering with a scalpel blade causing an iatrogenic complication and how this prevented the correct expansion of the stent and therefore the impossibility of deployed it or retrieve it into the Mullins sheath.…”

What Interventional Cardiologists Are Still Leaving to the Surgeons?

“…However, in branch pulmonary artery stenoses, standard BA may have success rates of 50–60% with a recurrence rate of 15% and complication rate of 6–12% ( 88 , 90 – 92 ). High-pressure and cutting balloons improved the success rates, especially in younger patients with resistant lesions ( 93 , 94 ). However, with continuous improvement of the stent technology, in most patients, stenting has become a treatment of choice for branch pulmonary artery stenosis.…”
