Early and long-term outlook of percutaneous coronary intervention for bifurcation lesions in young patients.

Background: Coronary artery disease is most common in older patients, but may occur in younger subjects. The outlook of young patients after percutaneous coronary intervention (PCI) of challenging lesion subsets such as coronary bifurcations, is not established. We thus aimed to appraise the early and long-term results of PCI for bifurcations in young patients.

Simplifying clinical risk prediction for percutaneous coronary intervention of bifurcation lesions: the case for the ACEF (age, creatinine, ejection fraction) score.

Aims: We aimed to appraise the predictive accuracy of a novel and user-friendly risk score, the ACEF (age, creatinine, ejection fraction), in patients undergoing PCI for coronary bifurcations.

Methods And Results: A multicentre, retrospective study was conducted enrolling consecutive patients undergoing bifurcation PCI between January 2002 and December 2006 in 22 Italian centres. Patients with complete data to enable computation of the ACEF score were divided into three groups according to tertiles of ACEF score.

Is intravascular ultrasound beneficial for percutaneous coronary intervention of bifurcation lesions? Evidence from a 4,314-patient registry.

Background: Coronary bifurcations remain a challenging lesion subset for percutaneous coronary intervention (PCI). It is unclear whether intravascular ultrasound (IVUS) guidance can improve PCI results in bifurcations. We aimed to compare IVUS-guided PCI versus standard PCI in a large registry of patients undergoing PCI for bifurcations in the drug-eluting stent era.

Coronary-to-bronchial anastomosis: an unusual cause of hemoptysis.

Coronary-to-bronchial anastomosis (CBA) is a rare anomaly. This vascular abnormality may be subclinical or be responsible for several pathophysiological events and symptoms involving the respiratory and/or the coronary system. We report the case of a patient with hemoptysis caused by this anomalous coronary-to-bronchial communication, who was concomitantly affected by aortic stenosis and coronary artery disease requiring surgical treatment.

Impact of the elevation of biochemical markers of myocardial damage on long-term mortality after percutaneous coronary intervention: results of the CK-MB and PCI study.

Aims: Retrospective studies and post hoc analyses have suggested that mild elevations in the creatine kinase-MB (CK-MB) isoenzyme following percutaneous coronary intervention (PCI) may be associated with an increased risk of death in the long term. However, this finding is still controversial, and the prognostic significance of elevations of more sensitive markers of myocardial damage, such as the cardiac troponins, has not been established. In this multicentre prospective cohort study, we evaluated the influence of post-procedural elevations of CK-MB and troponin I (cTnI) on long-term mortality.

Coronary rotational atherectomy in current practice: acute and mid-term results in high- and low-volume centers.

We conducted a prospective observational study to evaluate the indications, technique, in-hospital and 9-month results of consecutive patients treated with rotational atherectomy (RA) in 12 centers during 1 year, as well as their relationship with volume of RA activity. The study included 345 lesions in 289 patients treated (4.4% +/- 2.

Randomized evaluation of polytetrafluoroethylene-covered stent in saphenous vein grafts: the Randomized Evaluation of polytetrafluoroethylene COVERed stent in Saphenous vein grafts (RECOVERS) Trial.

Background: Treatment of lesions located in saphenous vein grafts (SVGs) is associated with increased procedural risk and a high rate of restenosis.

Methods And Results: We conducted a randomized, multicenter trial to evaluate the usefulness of a polytetrafluoroethylene (PTFE)-covered stent compared with a bare stainless steel (SS) stent for prevention of restenosis and major adverse cardiac events (MACE) in patients undergoing SVG treatment. The primary end point was angiographic restenosis at 6 months.

Coronary stent implantation is superior to balloon angioplasty for chronic coronary occlusions: six-year clinical follow-up of the GISSOC trial.

Objectives: We investigated whether the benefits of stent implantation over balloon percutaneous transluminal coronary angioplasty (PTCA) for treatment of chronic total coronary occlusions (CTO) are maintained in the long term.

Background: Several randomized trials have shown that in CTO, stent implantation confers clinical and angiographic mid-term outcomes superior to those observed after PTCA. However, limited information on the long-term results of either technique is available.

Rotational atherectomy does not reduce recurrent in-stent restenosis: results of the angioplasty versus rotational atherectomy for treatment of diffuse in-stent restenosis trial (ARTIST).

Background: Aim of this trial was to compare rotational atherectomy followed by balloon angioplasty (rotablation [ROTA] group) with balloon angioplasty (percutaneous transluminal coronary angioplasty [PTCA] group) alone in patients with diffuse in-stent restenosis.

Methods And Results: The ARTIST study is a multicenter, randomized, prospective European trial with 298 patients with in-stent restenosis>70% (mean lesion length, 14 +/- 8 mm) in stents, implanted in coronary arteries for >/= 3 months. In the PTCA group, angioplasty was performed at the discretion of the local investigator, and rotablation was performed by using a stepped-burr approach followed by adjunctive PTCA with low ( View Article and Find Full Text PDF
