Treatment of thoracic aortic rupture poses a substantial challenge for the aortic surgeon. The advent of thoracic endovascular aortic repair (TEVAR) revolutionized the treatment of this heterogeneous group of diseases. However, some patients suitable for TEVAR present severe peripheral vascular diseases which can prevent standard retrograde delivery of the stent-graft through the femoral artery. In this article, we present a case series of five patients with thoracic aortic rupture successfully treated with cardiac trans-apical TEVAR...

High-dimensional data provide many potential confounders that may bolster the plausibility of the ignorability assumption in causal inference problems. Propensity score methods are powerful causal inference tools, which are popular in health care research and are particularly useful for high-dimensional data. Recent interest has surrounded a Bayesian treatment of propensity scores in order to flexibly model the treatment assignment mechanism and summarize posterior quantities while incorporating variance from the treatment model...

Background: Good results of drug-eluting balloon (DEB) use are achieved in in-stent restenosis (ISR) lesions, small vessel disease, long lesions, and bifurcations. However, few reports exist about DEB use in acute myocardial infarction (AMI) with ISR. This study's aim was to evaluate the efficacy of DEB for AMI with ISR. Methods: Between November 2011 and December 2015, 117 consecutive patients experienced AMI including ST-segment elevation MI, and non-ST-segment elevation MI due to ISR, and received percutaneous coronary intervention (PCI)...

We present a 64-year-old woman who developed symptoms of acute pericarditis three days after undergoing intravesical instillation of mitomycin C following transurethral bladder tumor resection. Mitomycin C is a chemotherapeutic agent which acts by alkylation of DNA and is known to be cardiotoxic when systemically administered. Despite classic pericarditis symptoms, the patient underwent an urgent coronary angiogram due to elevated cardiac troponin I level, EKG changes, and wall motion abnormalities on her echocardiogram...

OBJECTIVE: The use of off-the-shelf stent grafts for thoracic endovascular aortic repair of type A dissections is limited by variability in both the length of the ascending aorta and the location of the proximal intimal tear. This experimental study aimed to assess the feasibility of using a physician-modified thoracic aortic stent graft to treat acute type A dissection by a transapical cardiac approach. METHODS: The experiments were performed on six cadaveric human heart, ascending aorta, aortic arch, and descending aorta specimens...

A 61-year-old man, who had undergone coronary artery bypass surgery 10 years earlier, presented with a non-ST segment elevation myocardial infarction. He was treated with medical therapy and taken to the Cardiac Catheterization Laboratory. A left heart catheterization demonstrated an ostial stenosis in the left internal mammary artery graft, which was felt to be the culprit lesion. This was successfully repaired with a drug eluting stent. This case is presented as an unusual location for a de novo coronary stenosis...

Background: A left ventricular (LV) thrombus is detected in approximately 5-10% of patients after myocardial infarction (MI). If left untreated, these LV thrombi carry a significant risk of complications including embolic stroke. According to current guidelines, anticoagulation with vitamin K antagonists (VKA) is recommended to treat a LV thrombus. Case presentation: An 87 year old patient was referred to our department with non ST-elevation MI. Five months before, he had been diagnosed with a subacute ST elevation MI, which had been treated conservatively...

BACKGROUND: It remains controversial whether coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI) should be optimized to treat coronary artery disease in patients on chronic hemodialysis (HD). Recently, further refinement of drug-eluting stents, such as the everolimus-eluting stent (EES), has led to marked development in this field. We compared long-term clinical outcomes after CABG versus PCI with EES implantation in patients on chronic HD. PATIENTS AND METHODS: We compared 138 patients undergoing CABG and 187 patients treated with EES implantation...

Coarctation of the aorta has been associated with increased thoracic aortic stiffness in adolescents and young adults. However, the effects of different therapeutic strategies on aortic stiffness in a young population is unknown. This study aimed to non-invasively assess aortic stiffness between different repair or intervention strategies in patients with coarctation of the aorta. Forty-nine coarctation patients who underwent either surgery (n = 26), balloon angioplasty (n = 14), or stent implantation (n = 12), and 26 age- and size-matched normotensive healthy controls underwent evaluation of thoracic aortic stiffness and flow hemodynamics via phase-contrast cardiac magnetic resonance...

Chronic heart failure (CHF) is still the leading cause of morbidity and mortality worldwide, and carries with it large economic and social burdens. Although steady and substantial progress has been made in reducing mortality from heart failure using conventional treatments, novel pharmacologic and surgical interventions have not been effective in extending five year survival rates. Therefore, it is necessary to explore new therapies. Gene therapy was introduced in 1970s with the development of recombinant DNA technology...
