cases of CHB. In these cases, a common finding, in addition to involvement of the aortic valve, was extension of the infection to adjacent structures resulting in cardioaortic fistulae. CHB likely resulted from extension of infection to the major conduction tissues. Five of the six patients with CHB died suddenly while in the hospital. One patient was treated with electric pacing while the infe...

Gram-negative bacterial endocarditis causes 5% of all bacterial endocarditis. Among gram-negative bacteria, Klebsiella species are rare causes of native valve endocarditis. Klebsiella oxytoca is an extremely rare subspecies that can infrequently cause endocarditis and is associated with poor outcome. We report a case of Klebsiella oxytoca endocarditis in an elderly man who initially presented w...

Introduction Congenital heart block (CHB) has long been associated with maternal anti-SSA/Ro antibodies. Injury to the conduction system is presumed to be a consequence of the transplacental passage of maternal IgG autoantibodies into the fetal circulation. Within the heart, a spectrum of phenotypes has been described, including structural defects, functional abnormalities, and electrical distu...

• The role of the electrical pacemaker with myocardial electrodes in the treatment of atrioventficular conduction blocks is an important one. Various observers, however, have reported a progressive increase in power needed to stimulate the heart and eventual failure of stimulation. The reason for this stimulation failure has been reported as due to increased electrical resistance from scar form...

CHEST, 71: 5, MAY, 1977 a major complication of this procedure, is reported in 10 to 50 percent of the cases.4’5 7 8 Although the indirect method of inferior vena cava interruption using an umbrella filter has resulted in significant reduction of morbidity and mortality, it is not free of complications. Because of the risks associated with different methods of inferior vena cava interruption, t...

A case of progressive systemic sclerosis is reported. The patient presented with chest pain and an abnormal chest radiograph. Later developments included cardiac involvement with complete heart block. The heart block was successfully managed with an implanted pacemaker.

211 Volume XI, no. 2 : May 2010 progressing from high-level AV block through second-degree to first-degree heart block before complete resolution.2 The AV node is most commonly involved, but any level of the conduction system can be affected. Clinical heart failure is observed in approximately 10% of patients, and dilated cardiomyopathy can be a long-term consequence of untreated Lyme carditis....

We report the occurrence of CHB consequent to ABV in an 80-year-old white woman with calcific aortic stenosis. The patient underwent ABV with a balloon 20 mm in diameter, resulting in only a modest increase in aortic valve area and a decrease in aortic valve gradient. The procedure was complicated by transient intermittent CHB which required temporary transvenous pacemaking and resolved within ...

In complete heart block, absolute independence between atrial and ventricular activity does not always occur. Several mechanisms may be postulated to explain this phenomenon. One is incomplete atrio-ventricular block; another is atrio-ventricular synchronization and accrochage (Marriott, 1956; Schubart, Marriott, and Gorten, 1958; Ettinger, 1965). A third possibility rarely considered is unidir...

tribution. More important, however, the possible existence of correlation among data was not addressed. It is generally known that correlation among data would seriously affect the results of analysis of variance. Therefore, it may be more appropriate to use a time series of analysis technique rather than the analysis of variance method. From the computational formula of the 95% confidence limi...
