Background: In patients with dilated (idiopathic) cardiomyopathy (DCM), little is known about the presence of valvular calcification and its association with hypovitaminosis D, which may predispose affected tissues to calcification. Our objectives were 2-fold: to conduct a retrospective assessment of echocardiographic evidence of valvular calcification in patients with DCM who were known to have hypovitaminosis D (25(OH)D <30 ng/mL) and to conduct a prospective assessment of serum 25(OH)D in patients with DCM, who had demonstrated echocardiographic evidence of valvular calcification.

Methods: The retrospective study consisted of 48 African American patients (34 men, 14 women; 52.

It was realized 20 years ago that the sonographic appearance of a diaphragmatic hernia could simulate a left atrial mass. Many papers have appeared on this topic since then, but they mainly consist of single case reports. Clinical symptoms due to cardiac compression by the hernia are uncommon but may occur if the hernia is very large; such patients have presented with episodes of syncope or dyspnea, typically after a large meal.

A patient with pericardial effusion and tamponade was studied by routine two-dimensional as well as three-dimensional echocardiogram. Chamber "collapses" of the right atrium, left atrium, right ventricle, and inferior vena cava were visualized by both modalities, but were better appreciated on three-dimensional echo imaging, perhaps because three-dimensional echo imaging is more suited to depicting three-dimensional changes in chamber shape.

The echocardiographic literature contains very scant reference to incompetence of the valve in the internal jugular vein. However, we found frequent Doppler evidence of such incompetence, especially in patients with congestive failure. This incompetence manifests as a variety of color Doppler and pulsed Doppler patterns, illustrated here in 3 patients.

The case of a 57-year-old male with a history significant for myeloproliferative disease, chronic renal failure, hypertension, and prostate cancer is described. His complete blood count was remarkable for neutrophilia and, notably, eosinophilia. Subsequent to two syncopal episodes, a transthoracic echocardiogram was performed as part of the workup, which showed an unusual calcified mass in the left ventricular apical region but separate from the apical myocardium, with normal left ventricular systolic function.

Color flow Doppler has been useful in diagnosing the presence and severity of mitral regurgitation (MR). We noted a hitherto unreported sign of MR due to flail mitral leaflet: intense local mosaic pattern at the site of the flail leaflet. This sign was seen well in 11 of 14 patients (79%) with the two-dimensional echocardiographic features of flail mitral leaflet, all with moderate or severe MR.

The anatomy and applied echocardiographic anatomy of the superior vena cava (SVC) are briefly described. Right supraclavicular interrogation of the SVC has been in use for many years, but supraclavicular two-dimensional (2-D) imaging of the SVC has been virtually ignored. We have recently shown that supraclavicular 2-D imaging can provide excellent views of the SVC and its main tributaries.

The usual echocardiographic appearances of the atria in heart transplant patients are well known. We report a case of an 81-year-old man with a 16-year-old cardiac transplant who showed a "new" echocardiographic left atrial abnormality. Two-dimensional echocardiography showed a large sonolucent space behind the donor left atrium (DLA), which was at first perplexing.

Objective: We hypothesized that functional mitral and tricuspid valvular incompetence (MR and TR, respectively) are reversible causes of reduced cardiac output in decompensated heart failure (DF) that accompanies systolic dysfunction in ischemic or nonischemic cardiomyopathy.

Background: DF, defined as signs and symptoms of heart failure at rest, is rooted in a salt-avid state transduced by neurohormonal activation secondary to impaired renal perfusion. Functional MR and TR are reversible causes of reduced systemic blood flow.

The coronary sinus (CS) can be imaged echocardiographically as a small tubular sonolucency in the posterior atrioventricular groove. To date, its importance to echocardiographers has been that CS dilatation usually signifies a persistent left superior vena cava. Recently, we developed a technique to image CS caliber over the duration of the cardiac cycle.

The chest radiographic, echocardiographic (transthoracic and transesophageal), MRI, CT and cardiac catheterization findings in a 72-year-old patient with extensive pericardial lipomatosis are presented. Diastolic pressures in the left heart were elevated. The massive lipomatous mass was partially resected surgically with good symptomatic relief.

A 52-year-old man with a history of chronic hypertension presented with worsening dyspnea and leg edema. He had been on minoxidil for 10 years. The cardiac silhouette was markedly enlarged.

It has been known for some time that mitral annulus calcification is common in end-stage renal disease (ESRD) patients on long-term dialysis, as well as in elderly patients without renal failure. However, a systematic comparison of cardiac calcification in these two types of patients has not yet been made. We examined two-dimensional echocardiograms in 33 patients with ESRD (mean age 66 +/- 10 years) and in 34 other patients with intracardiac calcification but no ESRD (mean age 69 +/- 9 years), with particular attention to precise anatomic location of calcification.
