William O’Neill: I have a couple of questions for both of you. First, we are essentially talking about adult, autologous stem cells. As you all know, there is enormous controversy in the U.S. about the use of embryonic stem cells which we are current…
Iatrogenic renal artery perforation is a rare, but well-described complication of percutaneous renal artery intervention.1–3 Treatment has traditionally involved surgical intervention including renal artery reconstruction, bypass grafting, and even n…
The transradial approach for percutaneous coronary interventions represents an effective and safe alternative to the traditional transfemoral approach, allowing earlier ambulation and discharge, greater comfort for the patient, and less vascular comp…
Since the use of combined antiplatelet therapy with aspirin and thienopyridines, the incidence of stent thrombosis is uncommon. Moreover, late stent thrombosis (> 30 days after stent implantation) is extremely rare with bare metal stents except af…
The prevailing cause of mitral stenosis (MS) is a progressive reaction to an injury caused by one of the major manifestations of rheumatic fever (RF): rheumatic carditis. The mitral is the valve most commonly prone to suffer a rheumatic process. Ther…
Atherosclerotic coronary artery disease is infrequently associated with ectasia and aneurysms due to extreme positive remodelling.1 Coronary artery aneurysms have been excluded with coil embolization, autologous saphenous vein-covered stent grafts, a…
The optimal treatment of bifurcation disease remains a challenging clinical problem.1 Although numerous techniques and strategies have been explored and reported,2–7 including “crushing” a drug-eluting stent with another drug-eluting stent, significa…
Myelodysplastic syndrome is a clonal hematopoietic stem-cell disorder characterized by cytopenia caused by inadequate proliferation and differentiation of blood cells due to dysmorphic or abnormal cellular bone marrow. When the megakaryocytic series…
George Dangas: There have been many attempts and many failures in this field due perhaps to the inherent tendency of interventional cardiologists to move quickly and work from assumptions, applying what may not yet be well understood. Gene therapy a…
Several clinical studies have demonstrated that diabetes mellitus is an important predictor of angiographic restenosis and late mortality after conventional balloon angioplasty.1,2 Stent implantation has been shown to improve the clinical outcomes fo…
