Since the emergence of stents, there has been persistent improvement in flexibility and deliverability of stents with modifications in its design and number of connectors. This has unfortunately created negative effect on longitudinal strength of stent resulting into a recently recognized and unaccustomed complication, longitudinal stent deformation (LSD). It is an abrupt shortening of the stent along its longitudinal axis, usually after deployment, due to various reasons. We present a case of LSD in Promus Element stent implanted at proximal left anterior descending artery...

INTRODUCTION: Atrial fibrillation (AF) is the most common arrhythmia affecting patients in open heart ICU after coronary artery bypass grafting (CABG). Most cardiac surgery textbooks recommend beta blockers as the drug of choice for treating such a condition while many experienced physicians and a number of anesthesiology references offer amiodarone as the drug of choice. Therefore, because of insufficient evidence and the aforementioned controversy, we decided to conduct a study evaluating these two antiarrhythmic medicines...

Development of coronary artery aneurysm (CAA) after implantation of drug-eluting stent is occasionally observed. We present a case of a 67-year-old man who underwent everolimus-eluting stent (EES) implantation in right coronary artery (RCA) for inferior wall myocardial infarction, and thereafter, giant CAAs were developed in the vessel of stent deployment, within 2 months. However, the patient was managed with coronary artery bypass grafting (CABG). On follow-up, the patient's condition was stable. To the best of our knowledge, we report the first case of occurrence of EES-associated giant CAAs in RCA subsequently treated with CABG...

Atrial septal defect (ASD) is a congenital heart defect that is being increasingly treated using percutaneous interventions. However, these techniques are not devoid of complications. One such complication is device embolization. Removal of such closure device poses tremendous risk and consequent complications both by percutaneous retrieval and surgical removal. Herein, we present two cases of ASDs that were closed using atrial septal occluder, but the devices were subsequently embolized into left atrium. These devices were then percutaneously retrieved without any further complication or injury...

In recent years, the paradigm about the metal with improved corrosion resistance for application in surgery and orthopedy was broken. The new class of biodegradable metal emerges as an alternative for biomedical implants. These metals corrode gradually with an appropriate host response and release of corrosion products. And it is absolutely necessary to use essential metals metabolized by hosting organism with local and general nontoxic effect. Magnesium serves this aim best; it plays the essential role in body metabolism and should be completely excreted within a few days after degradation...
