Coronary artery fistula (CAF) is a rare anomaly of the coronary artery. The draining site of a right coronary artery (RCA) fistula may usually be the right ventricle, right atrium, or pulmonary artery. Here, we present a patient with right coronary artery to coronary sinus fistula (RCACSF) complicated by aneurysmal dilatation of the coronary sinus (CS) and stenosis of CS ostium.

PURPOSE: Management of patients with mitral stenosis (MS) depends heavily on the accurate quantification of mitral valve area (MVA) using echocardiography. All currently used two-dimensional (2D) methods have limitations. Estimation of MVA using the proximal isovelocity surface area (PISA) method with real time three-dimensional (3D) echocardiography may circumvent those limitations. We aimed to evaluate the accuracy of 3D direct measurement of PISA in the estimation of MVA. METHODS: Twenty-seven consecutive patients (median age of 63 years; 77...

We report a clinical case of a 40-year-old male with surgically corrected congenital heart disease (CHD) 10 years earlier: closure of ostium primum, mitral annuloplasty, and aortic valve and root surgery. The patient was admitted with acute heart failure. Transesophageal echocardiography (TEE) revealed a dysmorphic and severely incompetent aortic valve, a partial tear of the mitral valve cleft repair and annuloplasty ring dehiscence. A true left ventricular-to-right atrial shunt confirmed a direct Gerbode defect...

Pulmonary arterial pressure is an important index in cardiovascular disorders, especially for pulmonary hypertension (PH). Doppler echocardiography (DE) is widely used as a noninvasive method to assess pulmonary arterial pressure. However, recent studies have found several hemodynamic factors that affect its accuracy in estimating systolic pulmonary arterial pressure (sPAP). But the effect of tricuspid regurgitation (TR) has not been investigated. Therefore, our study is aimed to determine whether the severity of TR will affect the accuracy of sPAP measured by DE in an unselected patient population...

Ostial lesions represent a challenging clinical scenario and percutaneous intervention (PCI) of left main coronary artery ostial lesions has been associated with postintervention complications, including protrusion of deployed stents into a sinus of Valsalva or aortic root. We report a case of stent protrusion into the aortic root following aorto-ostial left main coronary artery PCI, in which three-dimensional transesophageal echocardiography (3DTEE) provided incremental benefit over standard two-dimensional images...

AIMS: Mitral valve aneurysms (MVA) are most frequently associated with endocarditis. Echocardiography is the method of choice for diagnosis, and color flow imaging is an important, easy method to detect MVA ruptures. We aimed to study the clinical and echocardiographic findings and their relation to the mechanism of aneurysm formation. METHODS AND RESULTS: We reviewed clinical and echocardiographic records of 18 patients during a 17-year period, corresponding to 0...

As a result of improvements in congenital heart surgery, there are more adults alive today with congenital heart disease (CHD) than children. Individuals with cardiac birth defects may be able to participate in physical activities but require proper cardiovascular evaluation. The American Heart Association and American College of Cardiology released guidelines in 2015 for athletes with cardiovascular abnormalities. The guidelines express that although restriction from competitive athletics may be indicated for some, the majority of individuals with CHD can and should engage in some form of physical activity...

Left ventricular outflow tract obstruction (LVOTO) and systolic anterior motion (SAM) of the mitral valve may have various etiologies, of which hypertrophic cardiomyopathy is the most common. More rarely, an acute coronary syndrome, myocardial stunning, and takotsubo cardiomyopathy may give rise to LVOTO and SAM. Here, we present a 70-year-old female patient with a non-ST-elevation acute coronary syndrome treated with percutaneous coronary intervention. Echocardiography the day after, because of dyspnea and hypotension, revealed apical akinesia, LVOTO, and SAM, which proved completely reversible after treatment with a β-blocker and a 2-month follow-up period...

Ectopic thyroid is a rare congenital embryonic anomaly. Ectopic thyroid tissue can be located anywhere during its descent, but it is found primarily at the base of the tongue and in the mediastinum. It is very rarely found in the heart. Here, we report a rare case of cardiac ectopic thyroid tissue in a 53-year-old woman who presented with chest pain. Echocardiography revealed an intracardiac mass that was removed successfully. Histopathology confirmed that the mass was thyroid tissue without malignancy.

An 11-year-old girl was admitted to pediatric emergency unit with complaints of fatigue and cough. The patient had no previous complaints. There was no history of rheumatic heart disease. The height and duration of the P-wave was 4 mm and 0.16 seconds, respectively (p mitrale). Echocardiography showed enlarged left atrium (51×61 mm in diameter). Both the anterolateral and posteromedial papillary muscles were directly attached to the anterior and posterior mitral valve leaflets without tendinous chords. The patient was diagnosed with mitral arcade, severe mitral stenosis, and mitral regurgitation...

BACKGROUND: Body surface area (BSA)-indexed Z-scores are used to assess the ascending aorta (AAo) and diagnose aortic dilation (AoD) in children. BSA is directly related to body weight and corresponds to body mass index (BMI). We hypothesized extremes in BMI alter interpretation of aortic size in pediatric patients with AoD. METHODS: We reviewed all echocardiograms with a diagnosis of AoD performed at our institution from January 2013 through June 2013. Those with an age <2 or >20 years, history of aortic root surgery, or inadequate images were excluded...

Left ventricular aneurysm (LVA) is rare but potentially fatal complication of myocardial infarction. It has been strictly defined as a distinct area of abnormal left ventricular diastolic contour with systolic dyskinesia or paradoxical bulging. It may be asymptomatic. However, complications including thromboembolism, heart failure, valvular regurgitation, arrhythmia, and rarely rupture may be the initial presentation. Diagnosis may be established by transthoracic echocardiography, left ventriculography, computed tomographic angiography, and cardiac magnetic resonance imaging...

A 76-year-old man was admitted to our emergency department owing to chest pain, which started immediately after lunch. Although electrocardiogram revealed ST-segment elevation with hyperacute T-wave changes in the anterior lead tracings, emergency coronary angiography revealed normal coronary arteries. Echocardiography revealed left ventricular (LV) compression with left ventricular obstruction (LVO) caused by an echogenic mass. Computed tomography clearly revealed compression of both left atrial (LA) and LV by a large hiatal hernia...

BACKGROUND: The assessment of hemodynamic change by echocardiography is clinically useful in patients with pulmonary hypertension. Recently, mild elevation of the mean pulmonary arterial pressure (PAP) has been shown to be associated with increased mortality. However, changes in the echocardiographic indices of right ventricular (RV) function are still unknown. The objective of this study was to validate the relationship between echocardiographic indices of RV function and right heart catheterization variables under a mild RV pressure overload condition...

Sinus of Valsalva aneurysm is a rare congenital cardiac abnormality and is usually diagnosed when it ruptures. An asymptomatic 55-year-old male of unruptured sinus of Valsalva aneurysm of noncoronary cusp was on medical follow-up. At 2-year follow-up, there was thrombus formation in the aneurysm, mimicking right atrium tumor on 2D transthoracic echocardiography. Cardiac computed tomography showed filling defect in the aneurysm suggestive of thrombus. Considering the high risk of systemic emboli surgery was performed, and aneurysm was repaired with Dacron patch...

Nonalcoholic fatty liver disease may range from simple steatosis to fibrosis and cirrhosis. It is associated with the development of coronary artery calcification and appears to be an independent predictor of future adverse cardiovascular events. As the presence of a fatty liver appears to portray an independent increased risk, it may be beneficial to note this on coronary artery calcium scoring reports. Determination of fatty liver is relatively easy to perform. We discuss the method used by the Multi-Ethnic Study of Atherosclerosis (MESA) study for determination of fatty liver from CT coronary artery calcium scoring acquisitions, which may be implemented in clinical analysis...

BACKGROUND: Quantitation of regurgitation severity using the proximal isovelocity acceleration (PISA) method to calculate effective regurgitant orifice (ERO) area has limitations. Measurement of three-dimensional (3D) vena contracta area (VCA) accurately grades mitral regurgitation (MR) severity on transthoracic echocardiography (TTE). METHODS: We evaluated 3D VCA quantitation of regurgitant jet severity using 3D transesophageal echocardiography (TEE) in 110 native mitral, aortic, and tricuspid valves and six prosthetic valves in patients with at least mild valvular regurgitation...
