tant contribution in the evolution and refinement of diagnostic techniques that began when Barlow's angiographic observations provided the first rational basis for the origin of apical late systolic murmurs.3 Intracardiac phonocardiography subsequently recorded the clicks and late systolic murmur within the left atrium, a site appropriate for auscultatory events originating in the mitral appara...

Is the most common congenital defect in dogs. It is a LR shunting defect resulting from failure of closure of the left sixth aortic arch. If left untreated it results in left sided congestive heart failure. Clinically animals present with a Continuous (Machinery) Murmur at the left heart base with Hyperkinetic Femoral Pulses. A systolic murmur of mitral regurgitation may also be ausculted secon...

‘J’he patient is a 30-year-old asymptomatic man with a heart murmur first discovered two months prior to his referral to the Mayo Clinic for cardiac evaluation. Physical examination revealed right ventricular lift, grade 2/6 ejection systolic murmur at the pulmonic area, and persistently split second heart sound. A mid-diastolic flow murmur was heard at the left lower sternal border. The roentg...

Border electrokymograms of the cardiovascular silhouette in various views were obtained at approximately 1.0 cm. intervals in 28 subjects to determine the constancy and the specificity of the atrial border motion and to determine its ability to differentiate organic from functional apical systolic murmurs. Although a "plateau" curve previously reported as pathognomonic of organic mitral regurgi...

Coronary artery fistula is a rare organic heart disease. Its incidence rate is approximately 0.002%. Right coronary artery (RCA)–coronary sinus fistula is rare and most likely accounts for 7% of all coronary artery fistulas (1, 2). Most patients may present with chest pain, palpitations, syncope, and a continuous murmur at the precordium, accompanied by local thrill or a systolic and diastolic ...

For a number of years increasing attention has been paid to the evaluation of systolic murmurs (White, 1927; Fahr, 1930; Bass et al., 1933; Shapiro, 1939; White et al., 1942; Baker et al., 1943; Levy et al., 1943; Sodeman, 1944; and Master, 1948). It has been found that they are common in patients without evidence of cardiac disease, and the importance of considering factors other than organic ...
