coronary interventions (PCI) and the recent introduction of drug-eluting stents (DES) have led to a dramatic increase in the number of patients treated percutaneously. Bifurcation lesions are one of the complex lesion subsets that are now being confronted more frequently. Repeated studies have shown that bifurcation interventions, when compared to non-bifurcation procedures, have a lower rate o...
BACKGROUND Bifurcation lesions are frequent among patients with symptomatic coronary disease treated by percutaneous coronary intervention. Current evidence recommends a conservative (provisional) approach when treating the side branch (SB). OBJECTIVES The TRYTON (Prospective, Single Blind, Randomized Controlled Study to Evaluate the Safety & Effectiveness of the Tryton Side Branch Stent Used...
AIMS The treatment of coronary bifurcation lesions is technically challenging. Conventional 2-dimensional angiography lacks the ability to properly image the true bifurcation geometry or its plaque distribution. The objectives of this study were to reconstruct coronary bifurcation lesions in 3 dimensions (3D) and to analyse the geometric changes that may occur immediately after stenting. METH...
There are few reports of electrocardiogram (ECG) changes of conus branch occlusion. A conus branch artery supply to the outflow tract of right ventricle. A conus branch artery is considered as the substrate of Brugada syndrome. We report a case of conus branch occlusion during angioplasty with ST segment elevation in V1-3 like Brugada syndrome ECG. We need to bear in mind that this ECG change m...
OBJECTIVES The results of percutaneous balloon angioplasty for obstructed modified Blalock-Taussig (BT) or central shunts and pulmonary artery (PA) stenoses were studied to assess its role as an alternative to second shunt and surgical PA angioplasty. BACKGROUND Obstruction of a modified shunt and PA stenosis related to the shunt or ductus are not infrequent. A second shunt with or without PA...
Cardiac resynchronization therapy (CRT) using left- (LV) or biventricular pacing is widely applied in selected heart failure patients. However, transvenous LV-lead placement into coronary sinus (CS) branches can be challenging. A 77-year-old female patient with New York Heart Association class III symptoms due to dilated cardiomyopathy [LV ejection fraction (LVEF): 10%, QRS-duration: 150 ms], d...
BACKGROUND Excimer laser coronary angioplasty is a new, investigational technique for treating coronary artery stenoses. Initial reports have demonstrated acute efficacy and relative safety of this procedure, but have not addressed the effect of lesion type on acute success and complication rates. METHODS AND RESULTS In the first 100 patients undergoing percutaneous excimer laser coronary ang...
Background. Excimer laser coronary angioplasty is a new, investigational technique for treating coronary artery stenoses. Initial reports have demonstrated acute efficacy and relative safety of this procedure, but have not addressed the effect of lesion type on acute success and complication rates. Methods and Results. In the first 100 patients undergoing percutaneous excimer laser coronary ang...
PURPOSE Thromboembolic complications remain a limitation of flow diverting stents. We hypothesize that phosphorilcholine surface modified flow diverters (Pipeline Flex with Shield Technology, sPED) would have less acute thrombus formation on the device surface compared with the classic Pipeline Embolization device (cPED). METHODS Elastase-induced aneurysms were created in 40 rabbits and rando...
