Clinical characteristics and survival experience of out-of-hospital cardiac arrest victims without coronary heart disease.
Of 270 patients successfully resuscitated from out-of-hospital cardiac arrest, 16% had no evidence of coronary heart disease. In these 43 patients, other forms of heart disease were found in 81% (35/43): cardiomyopathy in 18 patients, valvular disease in six, congenital heart disease in two, and primary arrhythmia in nine. ⋯ One- and two-year mortalities were 30% and 43%, respectively, for the group, which is similar to one-year (20%) and two-year (35%) mortalities of the 227 resuscitated patients with coronary heart disease. Patients who survive a sudden death experience and who have no evidence of coronary artery disease are a unique but heterogeneous group who usually have identifiable cardiac or pulmonary disease.

Comparative StudyImproved diagnostic value of echocardiography in patients with infective endocarditis by transoesophageal approach. A prospective study.
In a prospective study, the clinical value of transoesophageal two-dimensional echocardiography (TOE) as compared with transthoracic two-dimensional echocardiography (TTE) was determined in patients with suspected infective endocarditis. Ninety-six patients were studied consecutively with an electronic sector scanner using 2.25 and 3.5 MHz probes for TTE and a 3.5 MHz probe embedded in tip of a flexible 12 mm gastroscope for TOE. Results of surgery and autopsy were available for 20 of the 96 patients with infective endocarditis and echocardiographically demonstrated vegetations and 70 control patients with valvular heart disease without infective endocarditis and no signs of vegetations, who were studied preoperatively with TTE and TOE. ⋯ TOE is superior to TTE in detecting vegetations in suspected infective endocarditis because of better image quality, particularly when vegetations are small. TOE seems to be indicated in patients with suspected endocarditis and reduced image quality or negative TTE results. Early detection of vegetations on valves may help confirm the diagnosis of infective endocarditis at an early stage and hopefully lead to an improved prognosis by reducing delay in instituting appropriate therapy.
