Editor’s Message

Dear Readers, This issue of the Journal of Invasive Cardiology continues our series of special focus sections to provide a more in-depth examination of important topics in cardiovascular medicine. The special section for this issue includes articles focusing on structural heart disease and issues in the treatment of congenital heart conditions in adults. The guest editor for this section is Dr. P. Syamasundar Rao from the University of Texas Medical Center in Houston, Texas. Dr. Rao has provided an introduction to the section and the articles that are featured this month. In addition to the focus section on structural heart disease, this issue of the journal includes original research articles, commentaries, a review article and a case report with interesting clinical images. Articles published online this month include case reports highlighting very late thrombosis in bare-metal stents, the occurrence of coronary artery air embolism causing pulmonary edema secondary to acute coronary syndrome in a diver, the use of cutting-balloon angioplasty in a hybrid setting involving the operating room, bail-out reverse controlled antegrade and retrograde subintimal tracking in the treatment of a chronic total occlusion, a report on the deployment of an implantable defibrillator in a patient with a tricuspid valve bioprosthesis, a case of takotsubo cardiomyopathy induced by chemotherapy, and a patient with late presentation involving drug-eluting stent fracture. These can be found on our website, and I encourage you to visit www.invasivecardiology.com to read these interesting and informative articles, as well as any past issues of the journal that you may have missed. The original research articles contained in this issue of the journal cover a variety of clinical topics. Daniela Frey and associates from the Swiss Cardiovascular Center and Experimental Surgery Institute and the Institute of Anatomy at the University of Bern in Bern, Switzerland, present their animal research studying the endothelialization of sirolimus-eluting stents with slow and extended drug release in the porcine overstretch model. In the next research article, Dr. Teruo Okabe and collaborators from the Cardiovascular Research Institute/Medstar Research Institute, Washington Hospital Center in Washington, D.C., and the Cardiovascular Research Foundation in New York, present their research reporting the five-year outcome of moderate or ambiguous left main coronary disease and the intravascular ultrasound predictors of events. Dr. Steven Goldberg of the editorial board has provided a commentary to accompany the Okabe et al article. Drs. Giorgio Gimelli and Matthew Wolff from the University of Wisconsin School of Medicine and Public Health in Madison, Wisconsin, report on their research investigating the impact of hemodynamically-supported percutaneous coronary revascularization in improving left ventricular function in patients with ischemic dilated cardiomyopathy at very high risk for surgery. Next, Francesco De Felice and colleagues from U.O. Cardiologia Interventistica in Rome, Italy, compared the 12-month outcomes of diabetic patients with chronic total occlusions after successful PCI who underwent drug-eluting stent implantation to that of patients with diabetes and CTO previously treated with bare-metal stents. Using a combined primary endpoint of death, myocardial infarction and repeat PCI or coronary artery bypass surgery, they conclude that drug-eluting stents were superior to bare-metal stents in reducing major adverse cardiac events. In the last original research article, Dr. Bon-Kwon Koo and associates from Stanford University Medical Center in Stanford, California, Dante Pazzanese of Cardiology, Sao Paulo, Brazil, and St. Vincent’s Hospital in Melbourne, Australia, present their study investigating the use of intravascular ultrasound analysis of small-vessel lesions treated with a novel ultra-low profile, guidewire-based, self-expanding stent system. Dr. Sanjeev Agarwal and colleagues from the Department of Cardiology, Rashid Hospital in Dubai and the Department of Cardiology at Washington Adventist Hospital in Takoma Park, Maryland, have provided a review article on very late thrombosis of drug-eluting stents. This issue is completed with a clinical image selection of a patient with a ruptured sinus of Valsalva aneurysm from Drs. Schneider, Jelnin and Ruiz of the Lenox Hill Heart and Vascular Institute in New York. It is my hope that these interesting articles and special focus on structural heart disease and challenges in the treatment of congenital conditions in this issue of the journal will provide important information to cardiovascular healthcare professionals so that they are able to provide state-of-the-art treatment for cardiovascular disease patients. Sincerely, Richard E. Shaw, PhD, FACC, FACA Editor-in-Chief
