..The causes of sustained monomorphic ventricular tachycardia (VT) after cardiac valve surgeries have not been studied extensively, although bundle-branch reentry has been reported...

..Due to under-representation of patients with renal disease in large clinical trials, outcomes of implantable cardioverter defibrillator (ICD) implantation in this group remain unclear...

..We sought to determine the incidence of increased QT(c) dispersion (QT(c-d)) relative to biopsy grade of severity of rejection...

..Because extensive medical data are available on this cross-sectional and diverse population, identification of the underlying causes of sudden death may promote health care policy to reduce the incidence of sudden death...

..Sudden cardiac deaths resulting from ACO were more likely to be associated with premortem exertional chest discomfort and/or syncope compared with deaths resulting from CAD...

..There was a trend toward earlier elevation of troponin-I and creatine kinase in patients with myocarditis compared with ACS...

..Computed tomography and pulmonary arteriography suggested a near immediate thrombogenic process. A multidisciplinary approach was utilized to identify management strategies that allowed for a satisfactory patient outcome...

..The purpose of this study was to assess the follow-up of patients with vaccinia-associated myocarditis...

..Of course, the only source they knew of a pacemaker was halfway around the world. We discuss the management of this injury in an austere combat environment...

..The prognostic importance of exercise-induced ventricular arrhythmia (EIVA) may be confounded by the presence of lower-risk idiopathic right ventricular outflow tract arrhythmias with left bundle-branch block (LBBB) morphology...

..Cardiovascular symptoms represent one of the leading nontraumatic causes of aeromedical evacuation from a combat zone. Whether the use of supplements is associated with a differential presentation to cardiovascular complaint is unknown...

..The purpose of this study was to define the incidence and characterization of cardiovascular cause of sudden death in the young...

..9 to 18.9). The rate was significantly higher for African-American female recruits (risk ratio 10.2, p <0.001). Sudden death with a structurally normal heart was the leading cause of death in female recruits during military training...

..Matrix metalloproteinases (MMPs) are enzymes involved in extracellular matrix degradation. The extrapolation of the role MMPs play in the clinical setting of acute coronary syndromes has not yet been defined...

..Lead extraction is increasingly necessary given the exponential growth in cardiac device implantation. Meanwhile, the tools, indications, and outcomes of this procedure continue to change...

..7 after adopting pre-vaccination cardiac screening (RR 1.4 [95% CI: 0.8-2.7]). Implementation of pre-vaccination cardiac risk factor screening was not associated with a reduction in cardiac events...

..Frequently the complication requires reoperation to examine the system. What do you do when everything seems to be working fine?..

..Recently, there has been interest in using nonstandard electrocardiographic (ECG) leads during exercise testing...

..Coexisting need for arteriovenous (AV) fistula placement is often contemplated relative to device placement. We describe the excimer laser lead extraction of a malfunctioning chronic atrial pacemaker lead ipsilateral to an AV fistula...

..Clinical features of young patients presenting with syncope have been underreported...

..Our study sought to determine if documentation of valvular heart disease on echocardiography resulted in an increased appreciation and documentation of precordial murmur...

....

..To evaluate supplement use, most notably ephedra, which has been temporally associated with sudden death. Animal models suggest increased myocardial irritability may predispose to primary arrhythmic death...

..We sought to determine whether aggressive education on evidence-based guidelines would affect the use of resources. Specifically, we sought to educate providers about the role of neuroimaging as well as sudden death risk stratification...

..CONCLUSION: Serum levels of MMP-9 were elevated in patients with mitral stenosis, providing further evidence that inflammation and ECM remodeling plays an important role in the pathophysiology of valvular heart disease...

..During military conflict, high-velocity injuries, including gunshot wounds (GSW) and fragment injury from improvised explosive devices (IED), are relatively more common...

..We sought to determine the incidence and outcomes of SAT following PCI with stent placement at a low-volume catheterization laboratory...

..009). Ventricular repolarization heterogeneity may serve as a marker of identifying high-risk patients after OHT...

..Excess postpercutaneous coronary intervention mortality in the elderly may be due to underlying comorbidities and not due to subsequent myocardial infarction or revascularization...

..6 +/- 11.3 vs. 2.1 +/- 2.2 days, p < 0.001). Of the 5.4% of patients who developed thrombocytopenia, only 2 patients (7.1%) required platelet or blood cell transfusion...

..8 +/- 1.6 cm). The CFA overlies the femoral head in 92% of cases. The femoral head has a consistent relationship to the CFA, and localization using fluoroscopy is a useful landmark...

....

..Atrial pacing consistently resulted in further widening of the first conducted QRS complex, and the physiology underlying this unusual finding is explored...

..Suggestive findings were demonstrated on cardiac catheterization and definitive diagnosis was made by magnetic resonance imaging. The use of MRI for the diagnosis of asymptomatic adult congenital heart disease will be reviewed...

..In our population it was cost-effective to screen all foreign-born individuals and those who had lived outside the United States...

....

..The cases were predominantly male (58/59; 98.3%) and White (51/59; 86.4%), both statistically significant associations (p = 0.0147 and p = 0.05, respectively)...

..The attitudes of these patients regarding these therapies and their perceptions of safety and efficacy have not been well defined...

..ICDs effectively terminate life-threatening arrhythmias in high-risk patients, with significant survival after first appropriate therapy...
