“…All M-mode echocardiograms were taken with a commercially available ultrasonograph using a 1.27 cm, 2.25 MHz, medium-focus transducer and a strip chart recorder. All 2-D echocardiograms were performed with wide-angle 84-degree phased-array ultrasonographs (Varian 3000 and 3400, using 2.5 and 3.5 MHz transducers) as previously described (Nair et at., 1982). All echocardiographic measurements were obtained according to previously described criteria (Henry et al, 1980;Sabn et al, 1978).…”

Summary: This retrospective study correlates the severity of calcific aortic stenosis detennined by twodimensional (2-D) echocardiography with the aortic valve area determined by catheterization in 57 patients. Aortic valve leaflet calcification was diagnosed by cineangiography in 50 (88 %) of 57 patients and by 2-D echo in 57 (100%) of 57 patients (p<0.025). An agreement between severity of aortic stenosis by catheterization and 2-D echo occurred in 22 (39%) of 57 patients. Chisquare and logistic regression analyses showed no correlation between the severity of aortic stenosis and the 2-D echo variables: left ventricular wall thickness, left ventricular diastolic dimension, left ventricular systolic dimension, aortic root diameter, and left atrial dimension. We conclude that 2-D echo detects aortic leaflet calcification better than cineangiography. However, the severity of aortic stenosis determined by 2-D echo correlates poorly with the severity of aortic stenosis determined by cardiac catheterization.

“…Mitral annular calcification (MAC) is associated with increased frequency of conduction problems, and there is a high prevalence of symptomatic bradyarrhythmias due to AVN and sinoatrial node disease in patients with MAC . However, no studies have evaluated the relationship between skin‐aging parameters and the incidence of degenerative advanced‐degree AV block.…”

Background Skin acts as a mirror to the internal state of the body. Hypothesis We tried to find the relation between skin aging parameters and the incidence of degenerative AV block. Methods This study included 97 patients divided into 2 groups; group D comprised 49 patients with advanced‐degree AV block, and group C comprised the 48 matched control group. All were subjected to full history taking, thorough clinical examination, calculation of intrinsic skin aging score, and resting 12‐lead surface electrocardiography (ECG). ECG for all patients assessed left ventricular end‐systolic diameter, left ventricular end‐diastolic diameter, ejection fraction, left atrium (LA) diameter, aortic root diameter, mitral annular calcification, aortic sclerosis. Coronary angiography was also performed when indicated for patients in group D. Results Patients in group D had a higher percentages of uneven pigmentation, fine skin wrinkles, lax appearance, seborrheic keratosis, total score > 7 (38 [77.55%] vs 10 [20.83%]), mitral annular calcification score of 33 (67.34%) vs 5 (10.41%), aortic sclerosis score of 21 (42.85%) vs 4 (8.33%), and mean LA diameter of 39.98 ± 5.52 vs 36.21 ± 3 mm (P < 0.001). Total score > 6 is the best cutoff value to predict advanced‐degree heart block with 89.79% sensitivity and 64.58% specificity. Seborrheic keratosis was the strongest independent predictor. Conclusions Any population with a total intrinsic skin aging score of >6 is at high risk for developing advanced‐degree AV block and should undergo periodic ECG follow‐up for early detection of any conduction disturbance in the early asymptomatic stages to minimize sudden cardiac death.

“…Several studies have found associations between MAC and ventricular and atrial enlargement, congestive heart failure, structural and functional impairment of the aortic and mitral valve, endocarditis, conduction defects, carotid artery stenosis, coronary artery disease and ischemic strokes (1)(2)(3)(4)(5)(6)(7). Furthermore, MAC is considered a marker of cardiovascular morbidity and mortality with pathogenesis and risk factors similar to atherosclerosis (e.g.…”
