INTRODUCTION: The aim of this study was to evaluate appropriateness of transesophageal echocardiography (TEE) studies based on 2011 Appropriate Use Criteria (AUC) for Echocardiography and its impact on patient management. METHODS AND RESULTS: In a retrospective analysis of 100 inpatient TEEs, 85% of the TEEs ordered were determined to be appropriate, 9% were inappropriate, and 6% were uncertain. Inter-observer differences in the determination of AUC were seen in 24% of the studies, requiring a senior-level cardiologist to make the final determination of AUC score...

Paravalvular regurgitation is an uncommon but serious complication that can be encountered after either surgical or percutaneous valve replacement and is associated with increased morbidity and mortality. Early detection and accurate assessment of paravalvular regurgitation are crucial to identify those who would benefit from intervention. Recent advances in 3-dimensional echocardiography have increased the feasibility of percutaneous approaches for the management of paravalvular regurgitation. Percutaneous closure of paravalvular regurgitation has emerged as a favorable alternative for redo surgery in selected cases...

BACKGROUND: Nonagenarians (NON) are a growing segment of the population and have a high prevalence of cardiac disease. Many findings encountered on their echocardiograms are also found in younger individuals with valvular or myocardial disease. Therefore, the purpose of this study was to describe this distinct echocardiographic phenotype. METHODS: We identified our study population by querying our echo database to identify unique septuagenarians (SEPT) and nonagenarians (NON) who underwent a transthoracic echocardiogram (TTE) from January 1, 2010 to December 31, 2014...

A rare and unusual form of myocardial rupture that can complicate acute myocardial infarction is intra-myocardial dissecting hematoma (IDH). Reports in the literature describing this entity are limited to case reports or series. The diagnosis prior to the advent of noninvasive imaging was at autopsy. We present a case of IDH occurring after acute anterior wall myocardial infarction that terminated fatally preceded by a hemodynamically unstable incessant ventricular tachycardia.

Cor Triatriatum Dexter (CTD) is a rare congenital anomaly involving the systemic venous valves. Failure of regression of the right-sided sinus venosus valve leads to abnormal septation of the right atrium and a variety of right atrial and tricuspid valve obstructive lesions. The presentation can be varied ranging from asymptomatic to persistent neonatal cyanosis. We describe a late diagnosis of CTD in a 10-month-old male with persistent hypoxia despite balloon valvuloplasty for mild pulmonic valve stenosis with a large secundum atrial septal defect and a mildly hypoplastic right ventricle...

BACKGROUND: Severe pulmonary hypertension (PH) has been associated with decreased post-kidney transplant survival and increased rate of long-term cardiovascular complications. Despite a high prevalence of PH in patients with end-stage renal disease, data on post-transplant renal allograft survival in recipients with pre-existing mild-to-moderate PH are limited. METHODS: The single-center retrospective study cohort consisted of 192 consecutive (2008-2015) renal transplant recipients with documented pretransplantation transthoracic echocardiogram (TTE) pulmonary artery systolic pressure (PASP)...

BACKGROUND: Left ventricular (LV) remodeling due to aortic regurgitation (AR) often leads to maladaptive responses. We assessed the prevalence and clinical implications of LV remodeling considering LV volume, mass, and relative wall thickness at the time of AR diagnosis. METHODS AND RESULTS: Between 2008 and 2017, 370 consecutive patients (mean age 67.3 ± 16.1 years, 56.5% males), with moderate or severe AR, were retrospectively analyzed. LV geometric patterns and clinical outcomes (cardiovascular death, hospitalization for heart failure, or aortic valve replacement) were evaluated...

BACKGROUND: Dipyridamole stress echocardiography (DSE) represents a fundamental test in patients with suspected coronary artery disease (CAD). The diagnosis of microvascular disease is still challenging. We aimed to determine the diagnostic value of left ventricular (LV) layer-specific longitudinal (LS) and circumferential strain (CS) by Speckle Tracking in detecting CAD during DSE and to study if they can help in discriminate between a negative echo and a suspected microvascular angina...

REVIEW

We reviewed the role of transesophageal echocardiography (TEE) in the management of renal cell carcinoma (RCC) with associated tumor thrombus. Many consider intraoperative TEE as imperative in cases of Level 4 thrombi with atrial involvement, as well as in cases that require the use of cardiopulmonary bypass (CPB). However, the role of TEE in the surgical management of RCC with associated inferior vena cava (IVC) thrombus may expand beyond this subset. When performed after induction, TEE provides updated information regarding tumor thrombus staging, which is essential for optimal surgical planning...

Focal thinning of the basal muscular ventricular septum is a characteristic morphological finding in cases of cardiac sarcoidosis, usually detected on the parasternal long-axis image during echocardiography. Surprisingly, however, its circumferential extent has rarely been demonstrated and discussed. We present a case showing typical thinning of the basal ventricular septum. The extent of circumferential wall thinning was evaluated using both echocardiography and cardiac computed tomography. The present case highlights the importance of detailed multiplanar and three-dimensional evaluation of this characteristic abnormality, more so because its mechanism as well as the precise impact on conduction has not yet been elucidated...

OBJECTIVE: In recent years, epicardial fat tissue (EFT) has been found to be strongly associated with the development of atrial fibrillation (AF) and post-ablation long-term recurrence. The current study investigated the procedural success rate of electrical cardioversion (ECV) and potential predictors of treatment failure in patients with nonvalvular persistent AF. METHODS: A total of 262 nonvalvular persistent AF patients who were scheduled for elective ECV were included in this prospective study...

Intermittent malfunction is a rare but potentially serious complication of prosthetic heart valve (PHV) replacement. It may be observed in both mitral and aortic valve prosthesis and may lead to either paroxysmal obstruction or regurgitation, depending on the valve location and on the phase of the cardiac cycle during which the leaflet is entrapped. The most frequently encountered causes of intermittent valve malfunction are pannus formation, prosthetic valve thrombosis, vegetations, and remnants of subvalvular apparatus such as chordae tendineae and suture material...

PURPOSE: Left atrial (LA) dilatation is predictive for complications in a multitude of cardiac diseases; therefore, adequate assessment is essential. Technological advances have made it possible to quantify LA function with Speckle Tracking Echocardiography (STE); however, there are currently no recommendations for normal values with regard to LA function. We aimed to assess LA myocardial and volumetric function in a healthy cohort and investigate correlations with baseline characteristics...

Left ventricular diverticula (LVD) are rare congenital anomalies usually detected incidentally in the adult population. Most commonly, they are found as a single left ventricular diverticulum in association with other congenital abnormalities but multiple LVD are exceedingly rare. We are describing a patient who was found to have multiple LVD on multimodality imaging studies. He had presented with a sudden cardiac arrest attributed to a combination of alcohol intoxication and QT interval prolongation from hypokalemia and antidepressant medications...

Left atrial (LA) masses are known to be associated with peripheral embolization. Accurate identification of etiology is crucial because treatment strategies may differ. We present the case of a young woman, who was initially diagnosed with a LA thrombus and anticoagulated. The diagnosis was revised to a primary cardiac tumor after review of the echocardiographic findings. Surgical excision revealed an atrial myxoma in an unusual location.
