BACKGROUND: Survivors of a myocardial infarction (MI) are at a considerable risk of developing further cardiovascular events, including recurrent MI, heart failure, stroke, and death. Patients with type 2 diabetes mellitus and stable ischemic heart disease (SIHD) have worse outcomes than their nondiabetic counterparts, and those with previous MI may be at particularly high risk. Yet, little is known about the effect of adding early revascularization to intensive medical therapy in this high-risk group...

BACKGROUND: Acute mesenteric ischaemia is a condition with a grim prognosis on conservative treatment. Endovascular revascularisation is a promising approach for some of these patients. CASE REPORT: We present the case of a 44-year-old woman with a history of severe arterial hypertension, left leg claudication, and overlooked symptoms of chronic mesenteric ischaemia for one year, who was admitted for severe abdominal pain for one week. Computed tomographic angiography (CTA) showed acute mesenteric ischaemia by occlusion of the coeliac trunk and the superior mesenteric artery (SMA), without bowel perforation...

OBJECTIVES: The presence of single coronary artery (CA) in the arterial switch operation (ASO) for neonatal treatment with transposition of the great arteries (TGA) has been reported to be an independent risk factor for early death after surgical repair and late reintervention. The study objective was to evaluate the mortality and the CA stenosis risk at early and long term in neonatal ASO for TGA and single CA. METHODS: Between January 1987 and January 2010, 979 neonates underwent an ASO, of which 73 had a single CA (7...

BACKGROUND: Patients with stable angina not controlled by monotherapy with nitrates, beta blockers, or calcium channel blockers are often treated with combinations of these drugs. There may be adverse effects from, or contraindications to, the use of combinations. In low risk groups, medical treatment appears to be as good an option as percutaneous transluminal coronary angioplasty in terms of averting myocardial infarction, death, or subsequent revascularization. Revascularization procedures are too costly or inaccessible for many patients in developing countries therefore effective and safe medical treatment is needed...

OBJECTIVES: To evaluate the safety and feasibility of subclavian artery stenting for coronary-subclavian steal syndrome (CSSS). BACKGROUND: CSSS is a rare cause of myocardial ischemia due to ipsilateral subclavian artery stenosis in patients who have undergone coronary artery bypass graft. However, current knowledge of the optimal therapy for CSSS is limited. METHODS: The clinical data of 37 patients (33 male; mean age 65 ± 6 years) with CSSS who had undergone subclavian artery stenting between April 2007 and December 2015 were analyzed...

Background The instantaneous wave-free ratio (iFR) is an index used to assess the severity of coronary-artery stenosis. The index has been tested against fractional flow reserve (FFR) in small trials, and the two measures have been found to have similar diagnostic accuracy. However, studies of clinical outcomes associated with the use of iFR are lacking. We aimed to evaluate whether iFR is noninferior to FFR with respect to the rate of subsequent major adverse cardiac events. Methods We conducted a multicenter, randomized, controlled, open-label clinical trial using the Swedish Coronary Angiography and Angioplasty Registry for enrollment...

Background In patients with ST-segment elevation myocardial infarction (STEMI), the use of percutaneous coronary intervention (PCI) to restore blood flow in an infarct-related coronary artery improves outcomes. The use of PCI in non-infarct-related coronary arteries remains controversial. Methods We randomly assigned 885 patients with STEMI and multivessel disease who had undergone primary PCI of an infarct-related coronary artery in a 1:2 ratio to undergo complete revascularization of non-infarct-related coronary arteries guided by fractional flow reserve (FFR) (295 patients) or to undergo no revascularization of non-infarct-related coronary arteries (590 patients)...

Background Coronary endarterectomy and patch angioplasty for the left anterior descending (LAD) artery have been shown to be effective adjunct techniques to surgical revascularization for severe coronary lesions. The objective of this study is to review the short- and long-term results of these two methods in our institution. Methods We retrospectively reviewed 166 consecutive patients who underwent internal thoracic artery grafting to the LAD, with either adjunct endarterectomy (95 patients) or patch angioplasty (71 patients) between 2002 and 2014...

Use of non-ionic contrast media (CM) in coronary arteriography has been reported to cause transient cortical blindness, confusion, amnesia and very rare focal deficits. We report a 69-year old patient with stabile angina pectoris who underwent coronary angioplasty with stent placement due to in-stent thrombosis of the right coronary artery who developed stroke symptoms with radiological suspicion of subarachnoid hemorrhage. No vascular malformations were detected on CT cerebral angiography. Dual antiplatelet treatment was continued...

BACKGROUND: Surgical revascularisation in patients with acute myocardial infarction with ST-Segment Elevation (STEMI) is usually considered as a second choice when direct angioplasty/stent fails. However, improvements in surgical technique and postoperative care may justify coronary artery bypass grafting (CABG) in STEMI. METHODS: This was a retrospective analysis of prospectively gathered data of 135 patients with acute STEMI, treated with CABG in our department from February 2008 to December 2012...

REVIEW
Fabien Picard, Serge Doucet, Anita W Asgar
The drug-coated balloon (DCB) has emerged as an additional tool in the arsenal of interventional cardiology devices; it delivers antiproliferative drugs to local arterial tissue by single prolonged coated balloon angioplasty inflation, and prevents restenosis, leaving no implant behind. This strategy theoretically decreases the risk of late inflammatory response to device components, without preventing positive remodelling. DCBs, when used carefully and with a good technique, may have a role in the treatment of lesion subsets, such as in-stent restenosis, small vessel disease or side branch bifurcations, in which the implantation of a drug-eluting stent is not desirable or is technically challenging...

Coronary tree matching is applied to plan percutaneous vascular procedures. This work, which allows following each segment of non-isomorphic coronary trees over time, precedes the determination of the best 2D angiography view from C-arm acquisition system for angioplasty procedure. To match two 3D coronary trees which represent two successive cardiac phases, we adapted a reference inexact tree matching algorithm based on association graph and maximum clique. To improve the pair-wise matching performance of our approach, artificial nodes are introduced to take into account the topology variation between 3D vascular trees...
