Abstract
Bioprostheses are prone to structural valve degeneration, resulting in limited long-term durability. A significant challenge when comparing the durability of different types of bioprostheses is the lack of a standardized terminology for the definition of a degenerated valve. This issue becomes especially important when we try to compare the degeneration rate of surgically inserted and transcatheter bioprosthetic valves. This document, by the VIVID (Valve-in-Valve International Data), proposes practical and standardized definitions of valve degeneration and provides recommendations for the timing of clinical and imaging follow-up assessments accordingly. Its goal is to improve the quality of research and clinical care for patients with deteriorated bioprostheses by providing objective and strict criteria that can be utilized in future clinical trials. We hope that the adoption of these criteria by both the cardiological and surgical communities will lead to improved comparability and interpretation of durability analyses.

Abstract
A 71-year-old man presented with New York Heart Association (NYHA) class IV heart failure. He had undergone transapical mitral valve replacement for mixed mitral stenosis and mitral regurgitation. At the 1 month follow-up, the patient reported symptom resolution. An echocardiogram revealed a low gradient and no regurgitation. Our case shows that with careful multidisciplinary evaluation, preoperative planning, and patient selection, percutaneous mitral intervention can become an alternative therapy for high-risk patients who cannot undergo conventional surgical therapy.

Abstract
True aneurysms of the internal mammary artery are rare and have been described in association with vasculitis or connective tissue disorders. Herein, we describe 2 cases of familial internal mammary artery aneurysms (IMAs) in 2 sisters with SMAD3 mutation. The older sister presented at the age of 54 years with an incidental diagnosis of a multilobed right IMA and the younger sister presented several years earlier with a ruptured left IMA aneurysm at the age of 49 years. Both sisters had Debakey type I aortic dissections prior to the IMA aneurysm presentation. To our knowledge, this is the first time IMA aneurysms have been described in siblings with SMAD3 mutation. In our experience, endovascular repair is a feasible and safe treatment option. An assessment of the entire arterial tree is recommended in patients diagnosed with SMAD3 mutations.

Abstract
Internal thoracic arteries (ITAs) should be used to bypass the left anterior descending (LAD) artery when bypass of the LAD is indicated (class of recommendation [COR] I, level of evidence [LOE] B). As an adjunct to left internal thoracic artery (LITA), a second arterial graft (right ITA or radial artery [RA]) should be considered in appropriate patients (COR IIa, LOE B). Use of bilateral ITAs (BITAs) should be considered in patients who do not have an excessive risk of sternal complications (COR IIa, LOE B). To reduce the risk of sternal infection with BITA, skeletonized grafts should be considered (COR IIa, LOE B), smoking cessation is recommended (COR I, LOE C), glycemic control should be considered (COR IIa, LOE B), and enhanced sternal stabilization may be considered (COR IIb, LOE C). As an adjunct to LITA to LAD (or in patients with inadequate LITA grafts), use of a RA graft is reasonable when grafting coronary targets with severe stenoses (COR IIa, LOE: B). When RA grafts are used, it is reasonable to use pharmacologic agents to reduce acute intraoperative and perioperative spasm (COR IIa, LOE C). The right gastroepiploic artery may be considered in patients with poor conduit options or as an adjunct to more complete arterial revascularization (COR IIb, LOE B). Use of arterial grafts (specific targets, number, and type) should be a part of the discussion of the heart team in determining the optimal approach for each patient (COR I, LOE C).

Abstract
With the evolution of transcatheter valve replacement, an important opportunity has arisen for cardiologists and surgeons to collaborate in identifying the criteria for performing these procedures. Therefore, The Society for Cardiovascular Angiography and Interventions (SCAI), American Association for Thoracic Surgery (AATS), American College of Cardiology (ACC), and The Society of Thoracic Surgeons (STS) have partnered to provide recommendations for institutions to assess their potential for instituting and/or maintaining a transcatheter valve program. This article concerns transcatheter pulmonic valve replacement (tPVR). tPVR procedures are in their infancy with few reports available on which to base an expert consensus statement. Therefore, many of these recommendations are based on expert consensus and the few reports available. As the procedures evolve, technology advances, experience grows, and more data accumulate, there will certainly be a need to update this consensus statement. The writing committee and participating societies believe that the recommendations in this report serve as appropriate requisites. In some ways, these recommendations apply to institutions more than to individuals. There is a strong consensus that these new valve therapies are best performed using a Heart Team approach; thus, these credentialing criteria should be applied at the institutional level. Partnering societies used the ACC's policy on relationships with industry (RWI) and other entities to author this document (http://www.acc.org/guidelines/about-guidelines-and-clinical-documents). To avoid actual, potential, or perceived conflicts of interest due to industry relationships or personal interests, all members of the writing committee, as well as peer reviewers of the document, were asked to disclose all current healthcare-related relationships including those existing 12 months before the initiation of the writing effort. A committee of interventional cardiologists and surgeons was formed to include a majority of members with no relevant RWI and to be led by an interventional cardiology cochair and a surgical cochair with no relevant RWI. Authors with relevant RWI were not permitted to draft or vote on text or recommendations pertaining to their RWI. RWI were reviewed on all conference calls and updated as changes occurred. Author and peer reviewer RWI pertinent to this document are disclosed in the Appendices. In addition, to ensure complete transparency, authors' comprehensive disclosure information (including RWI not pertinent to this document) is available in Appendix AII. The work of the writing committee was supported exclusively by the partnering societies without commercial support. SCAI, AATS, ACC, and STS believe that adherence to these recommendations will maximize the chances that these therapies will become a successful part of the armamentarium for treating valvular heart disease in the United States. In addition, these recommendations will hopefully facilitate optimum quality during the delivery of this therapy, which will be important to the development and successful implementation of future, less invasive approaches to structural heart disease.

Abstract
The inability to reposition or retrieve balloon-expandable transcatheter aortic valves once they have been deployed requires implantation of the valve in the descending aorta or open surgical procedures to extract the valve. We describe the challenging transfemoral delivery of an Edwards Lifesciences Sapien valve wherein we had difficulty crossing the aortic valve and the guidewire position was compromised. We performed a transapical puncture to snare the guidewire and create a left ventricular to femoral wire rail, allowing us to deliver the transfemoral transcatheter valve, salvaging a situation where we would have been required to implant the valve in the descending aorta. We believe this is the first time this technique has been reported and represents an important method to facilitate delivery of transcatheter valves where guidewire support is insufficient or lost.

Abstract
BACKGROUND Previous studies indicated that patients undergoing coronary artery bypass graft (CABG) surgery are less likely to receive guideline-based secondary prevention therapy than are those undergoing percutaneous coronary intervention (PCI) after an acute myocardial infarction. We aimed to evaluate whether these differences have persisted after the implementation of public reporting of hospital metrics. METHODS AND RESULTS The Clinical Outcomes Assessment Program (COAP) database was analyzed retrospectively to evaluate adherence to secondary prevention guidelines at discharge in patients who underwent coronary revascularization after an acute ST-elevation myocardial infarction in Washington State. From 2004 to 2007, 9260 patients received PCI and 692 underwent CABG for this indication. Measures evaluated included prescription of aspirin, β-blockers, angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers, or lipid-lowering medications; cardiac rehabilitation referral; and smoking-cessation counseling. Composite adherence was lower for CABG than for PCI patients during the period studied (79.6% versus 89.7%, P<0.01). Compared to patients who underwent CABG, patients who underwent PCI were more likely to receive each of the pharmacological therapies. There was no statistical difference in smoking-cessation counseling (91.7% versus 90.3%, P=0.63), and CABG patients were more likely to receive referral for cardiac rehabilitation (70.9% versus 48.3%, P<0.01). Adherence rates improved over time among both groups, with no significant difference in composite adherence in 2006 (85.6% versus 87.6%, P=0.36). CONCLUSIONS Rates of guideline-based secondary prevention adherence in patients with ST-elevation myocardial infarction who underwent CABG surgery have been improving steadily in Washington State. The improvement possibly is associated with the implementation of public reporting of quality measures.

Abstract
BACKGROUND We reviewed our experience with surgical procedures for infective endocarditis (IE) in order to evaluate modern outcomes and objectively examine our institutional preferences, including the use of bioprostheses in intravenous drug users (IVDUs) regardless of age and prompt surgical intervention in patients with either septic cerebral emboli or active infection. METHODS Review of medical records was conducted from February 1999 to November 2010. The Social Security Death Index was used to determine death from any cause in the postoperative period. Hospital records were used to identify infectious complications, recurrent endocarditis, and reoperation. RESULTS Sixty-four patients were identified as IVDUs and 133 patients as non-IVDUs. Survival at 30 days, 1 year, 5 years, and 10 years for IVDUs and non-IVDUs was 91.2% versus 93.6%, 77.5% versus 83.0%, 46.7% versus 71.1%, and 41.1% versus 52.0%, respectively. Cox regression analysis identified intravenous drug use as an independent risk factor for diminished survival (p=0.03), although not for reoperation (p=0.95) despite 95.3% of IVDUs receiving bioprostheses versus 73.7% of non-IVDUs (p=0.0002, Fisher's exact test). Forty-three patients were identified as having preoperative septic cerebral emboli; none had a perioperative hemorrhagic event. Active infection approached significance as an independent risk factor for the composite end point of recurrent IE and perioperative infection (odds ratio 2.8; 95% confidence interval, 0.777 to 10.9; p=0.12, Fisher's exact test). CONCLUSIONS Bioprostheses are reasonable for IVDUs undergoing valve replacement for IE regardless of age. Prompt surgical intervention in the setting of septic cerebral emboli is justified; in the setting of active infection it is less clear.

Abstract
BACKGROUND Heart transplant candidates carry many of risk factors for vascular disease, and in addition, recipients continue to accumulate them following heart transplantation (HTx). However, very limited information is available on this entity. This study was designed to address characteristics of extracoronary vascular disease in heart transplant recipients. METHODS This is a nonconcurrent cohort study of 402 patients who received HTx at the University of Washington between 1985 and 2004. Pretransplant arterial evaluation included carotid, lower extremity, and renal artery duplex studies. CT angiogram was obtained when indicated. Patients with severe arterial disease were excluded from the transplant list. Posttransplant vascular evaluation was done with the patient's history and physical examination. RESULTS Median follow-up was 5.5 years. Seventy vascular diseases were detected in 49 patients (12% of study population). Patients with pretransplant vascular disease, compared to those without, were older at the HTx, carried the diagnosis of ischemic cardiomyopathy more commonly, and had more comorbidities including history of smoking, alcohol drinking, chronic obstructive pulmonary disease, and prior heart operations. The prevalence of vascular disease was 6% prior to HTx and it cumulatively increased up to 17% at 17 years after HTx. Nineteen percent of these diseases were the result of arterial traumas mostly caused by medical interventions. Fourteen patients developed abdominal aortic aneurysm (AAA) with two deaths. CONCLUSIONS It is important for care providers to be aware of the high probability of vascular disease, to be familiar with vascular disease, and to provide appropriate prophylactic and therapeutic measures when evaluating this patient population.

Abstract
The clinical presentation, treatment, and outcomes of six consecutive patients presenting with acute aortic dissection secondary to hypertensive crises from methamphetamine use is described. Data were obtained prospectively from the expanded STS clinical database of the division of cardiothoracic surgery at the University of Washington, but reviewed in a retrospective fashion. These patients represent 5.5% of all patients diagnosed and treated for aortic dissection in the same time period (6/109) and 20% of all patients with aortic dissection under the age of 50 years (6/30). We conclude that young patients (<age 50 years old) presenting with acute aortic dissections should be routinely tested for methamphetamine. Positive urine tests should be confirmed with chromatography-mass spectrometry (GC-MS). Beta and alpha blockers should be used instead of the more typical beta blockade alone. We recommend the addition and documentation of intense, long-term drug rehabilitation program along with routine periodic clinical and radiographic follow-up to prevent secondary aneurysmal dilation of remaining pathological aorta.

Abstract
OBJECTIVE Elimination of cardiotomy suction increases reliance on cell-saver blood-conservation techniques. Reinfusion of processed cell-saver blood (PCSB) even without using cardiotomy field suction may contribute to thrombin, cytokines, platelet activators, and hemolytic factors measured systemically. DESIGN This study was designed as a prospective, unblinded observational study of patients undergoing first-time, nonemergent on-pump coronary artery bypass graft surgery. SETTING A university medical center. PARTICIPANTS Fourteen patients were enrolled after informed consent. INTERVENTIONS Arterial blood was sampled (1) before cardiopulmonary bypass, (2) immediately after bypass, and (3) 4 hours after bypass. PCSB, using the AutoLog (Medtronic, Inc, Minneapolis, MN), was sampled after bypass. MEASUREMENTS AND MAIN RESULTS Blood and PCSB levels of prothrombin fragments 1.2, beta-thromboglobulin, interleukin-6, interleukin-8, polymorphonuclear leukocyte-elastase, neuron-specific enolase, and S-100beta were assayed by using enzyme-linked immunosorbent assay. Paired comparisons were performed by using paired t tests. Compared with postbypass blood, processed cell-saver blood (prepatient infusion) had higher levels of polymorphonuclear leukocyte-elastase, interleukin-8, neuron-specific enolase, and S-100beta (p <or= 0.05). CONCLUSIONS Reinfusion of PCSB directly and independently contributes to systemic elevations in interleukin-8, polymorphonuclear elastase, neuron-specific enolase, and S-100beta, augmenting and perhaps accentuating the postoperative inflammatory response. Further evaluation and improvement in cell-salvaging technology and processing techniques are warranted.

Abstract
BACKGROUND Clinical studies conducted to elucidate the systemic response to cardiopulmonary bypass (CPB) did not differentiate possible effect of different types of cardiac surgical pathologies and operations on outcomes and have typically combined different procedures. We hypothesized that valve surgery induces more prominent systemic reaction compared to isolated on-pump CABG. METHODS Twenty-seven patients undergoing primary on-pump CABG (Group 1, n = 14) or valve surgery with or without CABG (Group 2, n = 13) were prospectively enrolled. Heparin-bonded circuits were used in all patients. Cardiotomy suction was only used in Group 2. Clinical and laboratory markers were evaluated. RESULTS Clinical measurements, including chest tube output, blood transfusion requirement, inotropic support requirement, and duration of ICU stay were not significantly different. Thrombin generation (PF-1.2) was significantly higher in Group 2 (p = 0.001). tPA was also significantly higher in Group 2 at 15 and 60 minutes on CPB (p < 0.01). Group 2 had significantly higher inflammatory response shown by elevation of IL6 (p = 0.005). Neuronal injury markers, S100beta and NSE, were significantly higher at the termination of CPB in Group 2 (p < 0.01). At no point of time course for any marker, Group 1 had significantly higher response compared to Group 2. CONCLUSIONS Valve surgery induced more prominent systemic response than CABG. The possible explanations include the difference in baseline disease pathophysiology, and/or difference associated with the procedures such as open systems and use of cardiotomy suction. Future clinical studies assessing systemic response to CPB and therapies to blunt these need consider and account for these observed differences.
