The history of percutaneous coronary intervention (PCI) is marked by rapid technological advancements that have taken place over the past 40 years. After a period of balloon angioplasty, which was marred by risk of abrupt vessel closure and vessel recoil, balloon expandable metal alloy stents were the mainstay of PCI. The introduction of drug eluting stents (DES) targeted in-stent restenosis, a common mode of stent failure, and ushered in the current PCI era. Since the first generation of DES, advances in polymer science and stent design have advanced the field. The current generation of DES has thin struts, are highly deliverable, have biocompatible or absorbable polymers, and outstanding safety and efficacy profiles. In this review, we discuss the technological advancements in stent development, design, and construction, with an emphasis on balloon expandable stents. The aspects of stent properties, metal alloys, bioresorbable vascular scaffolds, drug elution, and polymers will be covered.
functional disease. Whereas CCTA was inappropriate in this case, it would not have been if it were the primary test ordered. 1 Based on the CCTA data alone, it would be easy to misdiagnose this patient's condition as symptomatic CAD. This case presents a cautionary tale for how CCTA can promote overdiagnosis that has real consequences for patients.
The case of a 49-year-old patient is described who presented with cardiogenic shock and electrocardiographic signs of an inferolateral Q-wave infarction, and who received systemic lysis with anisoylated plasminogen streptokinase activator complex (Eminase). After coronary angiography had revealed only peripheral occlusion of a posterolateral branch of the left circumflex coronary artery, a pericardial effusion surrounding both right and left ventricular cavity was identified by echocardiography and was successfully drained via an inferior pericardiotomy with an immediate rise of blood pressure. Upon thoracotomy myocardial rupture was detected in the infarct area and was closed with mattress sutures. A total of 39 cases of successful surgical repair of myocardial free wall rupture reported in the literature is discussed. The mean age of patients was 59.6 +/- 1.3 years. Posterior and anterolateral infarctions were the preferred locations of myocardial rupture. Rupture occurred with a mean delay of 5.0 +/- 1.0 days after the onset of clinical infarct signs. Among patients saved by surgical means were 33 males and 6 females.
Patient: Male, 67Final Diagnosis: Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndromeSymptoms: Bilateral wrist swellingMedication: —Clinical Procedure: —Specialty: RheumatologyObjective:Unusual or unexpected effect of treatmentBackground:Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome is a rare clinical entity characterized by the sudden onset of inflammatory arthritis and marked pitting edema on upper and lower extremities. RS3PE is considered a rheumatic process distinct from rheumatoid arthritis, which may occasionally represent a paraneoplastic syndrome.Case Report:Herein, we describe a rare case of RS3PE associated with insulin therapy in a patient with no evidence of underlying malignancy.Conclusions:To the best of our knowledge, this is the first case report of RS3PE associated with insulin therapy. Physicians should look at the introduction of drugs as possible triggers for the development of RS3PE.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
