Abstract  A coronary sinus approach using a Gore-Tex Patch was used to repair an intracardiac left ventricular pseudoaneurysm after a previous bioprosthetic mitral valve replacement. At follow-up six months after surgery, echocardiography and a computed tomographic scan revealed almost complete obliteration of the pseudoaneurysm cavity. (J Card Surg 2012;27:692-695).

A Holter recording obtained from a patient with atrial fibrillation showed ventricular extrasystoles often in bigeminal rhythm. Most extrasystoles were followed by a long return cycle, and only in a few instances the postextrasystolic interval was short. The latter phenomenon was interpreted as a manifestation of poor retrograde concealed penetration ...

Myocardial bridging is a congenital coronary anomaly with a variety of clinical manifestations. Traditionally, myocardial bridging has been considered a benign condition, but some cases of myocardial ischemia, infarction and sudden cardiac death due to myocardial bridging have been reported. Various studies have suggested that in their intramyocardial segments, these ...

Functional mitral valve regurgitation (MR), a condition affecting millions of primarily elderly patients worldwide, is associated with poor clinical outcomes. Functional MR has traditionally been considered a disorder of regional or global left ventricular (LV) remodeling secondary to myocardial disease, in which anatomically normal leaflets fail to coapt adequately. The ...

Mitral regurgitation (MR) has been associated with adverse outcomes after myocardial infarction (MI). Without structural valve disease, functional MR has been related to left ventricular (LV) remodeling and geometric deformation of the mitral apparatus. The aims of this study were to elucidate the mechanistic components of MR after high-risk MI ...

This report describes the de novo occurrence of pacemaker-mediated tachycardia (PMT) in a patient with a dual-chamber implantable cardioverter-defibrillator and stable retrograde ventriculoatrial conduction time. The same rate-adaptive post-ventricular atrial refractory period (PVARP) duration had previously prevented PMT. Oversensing of atrial false signals from a defective lead shortened the PVARP ...

Although mineralocorticoid receptor (MR) antagonists are indicated in systolic heart failure, they are underprescribed in patients with appropriate indications for their prescription and often used in those in whom the evidence for probable benefit is scant. The rate of adverse events in practice has exceeded that foreshadowed by randomized controlled ...

Robotic navigation systems aim to improve ablation catheter maneuverability, tissue contact, and stability. These attributes suggest that such systems could enhance outcomes in the ablation of ventricular tachycardia (VT). To date, however, ablation has been confined to the atria. We present a case in which robotic catheter navigation alongside three-dimensional ...

Left ventricular aneurysm (LVA) describes a region of ventricular wall that is thinner than the adjacent myocardial segments, balloons outward and exhibits either akinesis or dyskinesis. Congenital LVA is diagnosed by exclusion with a very low incidence, especially in adult patients with very few cases reported. Clinically, most congenital LVA ...

In cardiac arrest, the ventricular fibrillation (VF) waveform, particularly amplitude spectral area (AMSA) and slope, predicts the return of spontaneous circulation (ROSC), but it is unknown whether the predictive utility differs in an acute myocardial infarction (MI), prior MI, or normal myocardium and if the waveform can distinguish the underlying ...

Acute elevation of circulating lipids, such as the postprandial state, contributes to increased cardiovascular risk. However, the effect of acutely elevated triglycerides on arterial and left ventricular function is not completely understood. We aimed to assess whether an acute increase in triglycerides affects ventricular-vascular interaction. Fifteen healthy men (aged 49±8yrs) ...

The healing process is a key determinant for postinfarction left ventricular (LV) remodeling and the development of heart failure, which could be influenced by mechanical (pressure and/or volume) load. So far, limited information exists regarding an indepth characterization of the postinfarct healing process in the mechanically unloaded state. In the ...

Measurements of cardiac troponin (cTn) and natriuretic peptides can predict outcomes after cardiac surgery and may thus assist in decision making about diagnostic and therapeutic steps in this setting. Not every cardiac surgical procedure is associated with the same degree of cTn or natriuretic peptide elevation; the factors known to ...

Cardiac dysfunction occurs commonly in sepsis. Impaired mitochondrial function is a potential cause of sepsis-associated myocardial depression. Cytochrome oxidase (COX), the terminal oxidase of the electron transport chain, is inhibited in the septic heart. Glutamine (GLN) increases Krebs cycle intermediates and supports oxidative phosphorylation. Exogenous GLN has been shown to ...

Mitral regurgitation is the most prevalent heart valve disorder in the United States. Individuals with mitral regurgitation may be asymptomatic or may present with dyspnea, orthopnea, fatigue, and/or heart rhythm disturbances. Long-standing mitral regurgitation causes chronic left ventricular volume overload, which leads to left ventricular dilation and contractile dysfunction. Without ...

Ventricular Tachycardia Storm in Cardiac Sarcoidosis. We describe the case of a 43-year-old male with cardiac sarcoidosis and ventricular tachycardia storm successfully treated with catheter ablation and immunosuppression. Antiarrhythmics alone, and in combination with immusuppressive agents, failed to successfully manage the ventricular tachycardia episodes. Catheter ablation in conjunction with immunosuppression ...

BACKGROUND: Remote ischaemic pre-conditioning and cardiac ischaemic post-conditioning provide myocardial protection in cardiac surgery. However, these two endogenous strategies have not been directly compared in a clinical setting. The purpose of this study was to compare the efficacy of remote ischaemic pre-conditioning and post-conditioning in providing myocardial protection to children ...

Ischemic postconditioning (IPOC) could be ineffective or even detrimental if the index ischemic duration is either too short or too long. The present study is to demonstrate that oxygen supply and metabolism defines a salvageable ischemic time window of IPOC in mice. C57BL/6 mice underwent coronary artery occlusion followed by ...
