1/297. Anomalous left coronary artery arising from right sinus of valsalva could be a minor congenital anomaly--a case report and review of the literature.Left coronary artery arising from the right sinus of valsalva is a rare congenital coronary anomaly. This anomaly is either benign or serious, depending on the relation of the anomalous left coronary artery to the aorta and pulmonary artery. Potentially serious anomaly is associated with sudden cardiac death and warrants prophylactic coronary bypass surgery. A rare case of anomalous left coronary artery arising from the right sinus of valsalva is reported, documented by coronary angiography; however, it took a safer course between the aorta and pulmonary artery. Prophylactic surgery was not performed, for this benign anomaly may not carry the same risk of sudden cardiac death.- - - - - - - - - - ranking = 1keywords = cardiac (Clic here for more details about this article) |
2/297. Potential proarrhythmic effects of implantable cardioverter-defibrillators.Implantable cardioverter-defibrillator (ICD) interventions have the potential to be proarrhythmogenic. New arrhythmias can occur in the setting of clinically appropriate therapies, as well as during a cardiac rhythm for which therapy is not intended. Cardioversion/defibrillation therapies, antitachycardia pacing, and antibradycardia pacing are potential triggers for the development of new arrhythmias. Newer ICDs allow better recognition and interpretation of the arrhythmias that are induced by delivered therapies. Two cases of ICD-induced proarrhythmias are described. Based on the course of these patients and review of previous reports, proarrhythmic effects of ICD interventions along with prevention and management strategies are discussed.- - - - - - - - - - ranking = 0.5keywords = cardiac (Clic here for more details about this article) |
3/297. cardiac tamponade and death from intrapericardial rupture [corrected] of sinus of valsalva aneurysm.A 35-year-old woman presented with dyspnea and chest pain. She had a large aneurysm of the non-coronary sinus of valsalva. Before her scheduled urgent surgery, the patient collapsed and died of cardiac tamponade secondary to intrapericardial rupture of the aneurysm. We would advocate urgent repair of this type of lesion to prevent such an outcome. We are aware of no other specific reports addressing extracardiac rupture of non-coronary cusp aneurysms [corrected].- - - - - - - - - - ranking = 1keywords = cardiac (Clic here for more details about this article) |
4/297. Combining nonpharmacologic therapies for advanced heart failure: the Munster experience with the assist device-defibrillator combination.Implantable cardioverter defibrillators (ICDs) and ventricular assist devices (VADs) have been used as a bridge to cardiac transplantation. In selected patients, the combined implantation may be required. This study was motivated by a case of a 33-year-old female patient with giant cell myocarditis who died of ventricular tachyarrhythmias after having been placed on a VAD with which she had been treated on an out-of-hospital basis for a prolonged period of time. A subsequent retrospective analysis of our data showed that, of 73 patients who had to be bridged mechanically (54 Novacor, 12 TCI Heartmate, 4 Thoratec, 3 Medos) in our institution between 1993 and 1998, 10 patients had undergone defibrillator implantation either before (n = 8) or after (n = 2) implantation of a VAD. The cases are presented, and the feasibility of the combination therapy discussed.- - - - - - - - - - ranking = 0.58333657146049keywords = cardiac, heart, heart failure (Clic here for more details about this article) |
5/297. Procuring organs from a non-heart-beating cadaver: a case report.organ transplantation is an accepted therapy for major organ failure, but it depends on the availability of viable organs. Most organs transplanted in the U.S. come from either "brain-dead" or living related donors. Recently organ procurement from patients pronounced dead using cardiopulmonary criteria, so-called "non-heart-beating cadaver donors" (NHBCDs), has been reconsidered. In May 1992, the University of Pittsburgh Medical Center (UPMC) enacted a new, complicated policy for procuring organs from NHBCDs after the elective removal of life support. Seventeen months later only one patient has become a NHBCD. This article describes her case and the results of interviews with the health care team and the patient's family. The case and interviews are discussed in relation to several of the ethical concerns previously raised about the policy, including potential conflicts of interest, the definition of cardiopulmonary death, and a possible net decrease in organ donation. The conclusion is reached that organ procurement from non-heart-beating cadavers is feasible and may be desirable both for the patient's family and the health care providers.- - - - - - - - - - ranking = 0.090177568403315keywords = heart (Clic here for more details about this article) |
6/297. Sudden death associated with group A streptococcal infection in an 8-year-old girl with undiagnosed hypertrophic cardiomyopathy.An 8-year-old girl died suddenly without prior symptoms. Post-mortem examination identified both systemic group A streptococcal infection and hypertrophic cardiomyopathy. She had no history of cardiac symptoms and was not in a high-risk group for sudden death due to hypertrophic cardiomyopathy. We believe the disseminated but asymptomatic group A streptococcal infection precipitated her early death from hypertrophic cardiomyopathy. Sudden unexpected death during systemic infection should be followed by post-mortem examination to look for evidence of hypertrophic cardiomyopathy, as this diagnosis has genetic implications for other family members.- - - - - - - - - - ranking = 0.5keywords = cardiac (Clic here for more details about this article) |
7/297. Sudden death after a cold drink: case report.We report a case of sudden cardiac death in a 12-year-old boy after rapid ingestion of a frozen slurry drink. The cause of death was determined to be a cardiac arrhythmia secondary to a previously undiagnosed cardiac rhabdomyoma with associated myocardial scarring. Ingestion of cold liquids has been associated with syncope, but not sudden cardiac death. In this case, bradycardia induced by cold-induced vasovagal reflex may have precipitated the terminal arrhythmia. Ingestion of cold liquids should be considered a potential trigger for fatal cardiac arrhythmias in patients with underlying heart disease.- - - - - - - - - - ranking = 2.5150295947339keywords = cardiac, heart (Clic here for more details about this article) |
8/297. The combination of risk factors for sudden death in a resuscitated elderly patient with an exceptional cause of left ventricular hypertrophy.The work-up of a previously asymptomatic 72-year-old man presenting with sudden cardiac death revealed a coarctation of the aorta as the cause of arterial hypertension, severe left ventricular hypertrophy, in combination with coronary artery disease with an apical myocardial infarction, severe autonomic dysfunction, and AV-nodal reentrant tachycardia. All these elements and their complex, probably synergistic interactions might have been involved in the development of sudden cardiac death.- - - - - - - - - - ranking = 1keywords = cardiac (Clic here for more details about this article) |
9/297. syncope in the pediatric patient. The cardiologist's perspective.The evaluation of syncopal children or adolescents relies heavily on a thorough, detailed history and physical examination. All syncope associated with exercise or exertion must be considered dangerous. The ECG is mandatory, but other laboratory tests are generally of limited value unless guided by pertinent positives or negatives in the history and physical examination. The ECG allows screening for dysrhythmias, such as wolff-parkinson-white syndrome, heart block, and long qt syndrome, as well as hypertrophic cardiomyopathies and myocarditis. Tilt table testing can be useful in selecting therapy by demonstrating the physiologic response leading to syncope in an individual patient. The most common type of syncope in otherwise healthy children and adolescents is neurocardiogenic or vasodepressor syncope, which is a benign and transient condition. Because syncope can be a predictor of sudden cardiac death, it must be taken seriously, and appropriate screening must be performed.- - - - - - - - - - ranking = 0.51502959473389keywords = cardiac, heart (Clic here for more details about this article) |
10/297. An interesting case of infant sudden death: severe hypertrophic cardiomyopathy in Pompe's disease.glycogen storage disease type ii (Pompe's disease) is a rare inherited metabolic disorder, which often leads to infantile death from severe cardiomyopathy. This case of sudden death illustrates the features of the cardiac findings in the disorder, resulting from massive lysosomal accumulation of glycogen in the heart and other tissues. Pompe's disease should be considered in cases of unexplained infantile cardiomyopathy.- - - - - - - - - - ranking = 0.51502959473389keywords = cardiac, heart (Clic here for more details about this article) |
