Randomized Controlled Trial Multicenter StudyPeriprocedural use of tirofiban in elective percutaneous coronary intervention for long coronary lesions in stable patients with overlapping drug-eluting stents--the PETITION study: a prospective, randomized, multicenter study.
Patients are at risk of developing periprocedural myonecrosis after percutaneous coronary intervention (PCI). We investigated whether the use of the platelet glycoprotein (GP) IIb/IIIa receptor inhibitor tirofiban could reduce periprocedural myocardial infarction (PMI) in patients with stable coronary artery disease undergoing elective PCI with overlapping stent implantation for long lesions. ⋯ Our results show that the adjunctive use of tirofiban reduces the occurrence of PMI and MACE at one year in stable coronary artery disease patients undergoing elective PCI for long lesions with overlapping stent implantation.

Comparative StudyDrug-eluting stents versus bare metal stents prior to noncardiac surgery.
The safety of drug-eluting stents (DES) vs. bare metal stents (BMS) in the perioperative setting, a heightened state of inflammation and thrombosis is not well defined. ⋯ DES implantation was not associated with higher adverse events after NCS. Moreover, the incidence of adverse events following NCS was lower when NCS was performed >90 days post-DES implantation suggesting that it may not be necessary to wait until 12 months post PCI with DES before NCS.

Optical coherence tomography-based predictors for creatine kinase-myocardial band elevation after elective percutaneous coronary intervention for in-stent restenosis.
We evaluated whether morphological characteristics of neointimal tissue of in-stent restenosis (ISR) lesions assessed by optical coherence tomography (OCT) affect periprocedural elevation of creatine kinase-myocardial band (CK-MB). ⋯ A greater axial length of neoatherosclerosis and the presence of TCFA at the most stenotic site were significantly associated with post-PCI CK-MB elevation in ISR lesions.

Case ReportsTranscatheter neoaortic valve replacement utilizing the Melody Valve in hypoplastic left heart syndrome.
Percutaneous transcatheter pulmonary valve replacement with the Melody Valve is fast becoming an important adjunct in the treatment of older children and adults with failing right ventricular outflow tract conduits. Recently, the Melody Valve has also been successfully implanted in the tricuspid, mitral, and aortic positions, typically within a failing bioprosthetic valve. ⋯ To our knowledge, this is the first successful use of the Melody Valve in the neoaortic position in a patient with single-ventricle physiology. Successful relief of neoaortic valve regurgitation using replacement with a transcatheter valve may allow avoidance of additional surgery, increase functional longevity of single-ventricle palliation, and postpone the need for orthotopic heart transplantation.
