Grade I diastolic dysfunction (DD) is generally associated with a normal mean left atrial pressure (LAP) and normal left ventricular end-diastolic pressure (LVEDP). The first hemodynamic alteration seen in DD, however, is the development of an elevated LVEDP with a persistent normal LAP. This is manifested by echocardiography as a continued mitral pulsed wave (PW) E/A <0.8 (Grade I DD), but with evidence of an elevated LVEDP. Such findings include alterations in PV flow, mitral PW inflow response to Valsalva maneuver, and also the presence of a B-bump on the mitral M-mode tracing...

Three-dimensional transthoracic echocardiography (3DTTE) may have a role in predicting final left ventricular volumes and clinical response after the surgical ventricular reconstruction (SVR) of left ventricular aneurysms and pseudoaneurysms. Left ventricle final volumes can be calculated through "virtual aneurysmectomy." We present a patient with a huge ventricular dilation combined with myocardial dissection, localized wall rupture, and aneurysm of the left ventricular apex after acute myocardial infarction in which accurate predictions from 3DTTE suggest potential clinical value...

We present the case of a 34-year-old female who was admitted to our hospital due to community-acquired pneumonia and had a transthoracic echocardiogram which revealed an aneurysm of the membranous interventricular septum. This was further investigated with a transesophageal echocardiogram which showed in detail the anatomical features of this very rare condition.

Isolated right superior vena cava drainage into the left atrium (RSVC-LA) is an extremely rare anomaly in the absence of other cardiac or extracardiac abnormalities. The clinical and echocardiographic diagnosis is considered challenging. We report a female infant with cyanosis on crying who was diagnosed as isolated RSVC-LA using conventional and contrast echocardiography, but further confirmation was possible via multidetector CT. The surgical correction was performed with smooth postoperative recovery. In conclusion, isolated RSVC-LA must be in the differential diagnosis of cyanosis in the absence of intracardiac anomalies...

BACKGROUND: The role of three-dimensional transesophageal echocardiography (3DTEE) vs multidetector computed tomography (MDCT) in aortic annular sizing has been poorly defined in patients undergoing transcatheter aortic valve replacements (TAVR). We set to determine the correlation between 3DTEE and MDCT in measuring the aortic annulus prior to TAVR. METHODS: In an observational, retrospective study, we compared aortic annular areas measured by MDCT and 3DTEE in TAVR patients...

INTRODUCTION: Hiatal hernia (HH) can cause left atrial (LA) compression and impair LA filling. We evaluated the cardiac effects of preload reduction and abdominal strain induced by Valsalva maneuver (VM) in large HH patients. METHODS: LA and left ventricular (LV) dimensions were measured using 2D transthoracic echocardiography at rest and during VM in HH patients (n=55, 70±10 years) and controls (n=22, 67±6 years). Biplane LV volumes (n=39) and mitral inflow pulse-wave Doppler parameters (n=27) were also evaluated...

BACKGROUND: An association between cardiomyopathy and celiac disease has been reported, but not frequently. We examined the effects on cardiac mechanics in children with celiac disease (CD) by two-dimensional speckle tracking echocardiography (2DSTE). METHODS: Eighty-one children with CD were compared with a control group comprising 51 healthy children by echocardiographic examination. Children with CD who had been on gluten-free diet for more than 6 months were divided into two different groups: group 1 was positive for serum antitissue transglutaminase antibody (n=48), and group 2 was negative for serum antitissue transglutaminase antibody (n=33)...

OBJECTIVE: The aim of the study was to assess the left ventricular (LV) synchronicity in pregnant women and to identify the main determinants of LV dyssynchrony in asymptomatic pregnant women. METHODS: One hundred sixty-seven pregnant women consecutively and 48 age-matched nonpregnant controls were enrolled. For the assessment of LV systolic dyssynchrony, the standard deviation of the time from QRS onset to peak systolic (Tps-LV- standard deviation [SD]) velocity and the maximal difference of the time from QRS onset to peak systolic velocity (Tps-LV) from 12 segments at the apical views...

BACKGROUND: With this study, we sought to investigate the prognostic value of echocardiographic tissue imaging markers in predicting tamponade among patients with large malignant pericardial effusion compared to routinely used echocardiographic signs. METHODS: A total of 96 consecutive patients with large malignant pericardial effusion, not in clinical cardiac tamponade, underwent an echocardiographic examination and were prospectively assessed for 1 month. Clinically evident cardiac tamponade was considered as the study endpoint...

BACKGROUND: Left ventricular (LV) contractile reserve assessed using imaging and cardiopulmonary exercise testing (CPX) has been shown to predict outcome in patients with dilated cardiomyopathy (DCM). Few clinical studies have, however, analyzed the relationship between them. METHODS: A cohort of 75 ambulatory patients with DCM underwent stress treadmill echocardiography with CPX. LV contractile reserve was calculated as absolute change (ΔLVEF=LVEFpeak -LVEFrest ) and percent change (%LVEF=[(LVEFpeak -LVEFrest )/LVEFpeak) ]×100) in LVEF, circumferential and longitudinal strain (LS)...

A 16-year-old girl was admitted with a 7-month history of recurrent fever, weight loss of 5 kg, and general poor health status. Blood culture was positive with Streptococcus viridans. Transthoracic echocardiography established an aneurysm of the root of left subclavian artery, associated with an aortic coarctation just before the origin of the left subclavian artery with a velocity of 4.8 cm/s. Three-dimensional echocardiography demonstrated the entire inner structure of the aneurysm. Computed tomography reconstruction confirmed the presence of aortic coarctation and mycotic aneurysm, it also revealed an aberrant right subclavian artery...

Subaortic obstruction due to systolic anterior motion (SAM) of the mitral valve with ventricular septal contact is a major cause of progressive heart failure symptoms in patients with hypertrophic cardiomyopathy (HCM). However, we have recently observed a unique, but not uncommon subgroup of HCM patients with outflow tract obstruction due only to discrete subaortic membrane or who have a membrane in addition to SAM-septal contact. HCM patients with subaortic membranes may be at increased risk for developing progressive heart failure symptoms...

A case of double aortic arch that was well visualized using transthoracic echocardiography is reported. A 38-year-old man underwent transthoracic echocardiography for the evaluation of dyspnea. A suprasternal view of transthoracic echocardiography showed the ascending aorta bifurcate to left and right aortic arches, with blood flow from the ascending aorta to bilateral aortic arches. The diagnosis of right side-dominant double aortic arch was made, and the patient's symptom was conceivably related to compression of the trachea due to a vascular ring...

BACKGROUND: Aortic root dilatation (ARD) in congenital heart disease is related to aortic aneurysm, rupture, and dissection. This study aimed to investigate the factors associated with ARD in patients with surgically repaired ventricular septal defect (VSD). METHODS: This cross-sectional study included 152 patients with surgically repaired VSD. Two definitions of ARD were used: (1) observed Valsalva diameter to body surface area (BSA) ratio >2.1 cm/m(2) and (2) absolute value of Valsalva diameter ≥4...

A 36-year-old female was admitted to hospital exhibiting chest pain, dyspnea, and a heart murmur on the right upper sternal border, radiating to both carotid arteries. The blood pressure of the patient's right arm exceeded the pressure in the left by 25 mm Hg (Coanda effect). In spite of laboratory results that did not fall outside the expected range, the left ventricle was revealed to be hypertrophic following electrocardiography. Transthoracic echocardiography revealed a severe supravalvular aortic stenosis (SVAS) with a peak Doppler velocity of 6...

Single coronary artery is an extremely rare congenital coronary anomaly in which the entire coronary arterial system arises from a solitary ostium. The Lipton's classification is used for single coronary artery anomalies. Herein, we present a 72-year-old woman with single coronary artery anomaly admitted with atypical chest pain. Coronary angiography and multidetector computed tomography coronary angiography findings were shared.

The aim of the study was to analyze possible correlations between strain echocardiography (STE) and PET myocardial perfusion in a population of heart transplantation (HTx) recipients showing preserved left ventricular (LV) ejection fraction. By STE, LV global longitudinal strain (LV GLS) was lower in HTx. PET showed no transient or chronic ischemia in 83 of 115 HTx (73%). Fixed perfusion defects were observed in 17% of HTx and reversible ischemia in 10%. Significant coronary stenosis was observed only in 10 cases...

Myxoma is a rare cause of severe mitral stenosis. We describe a challenging case of severe mitral stenosis and reversible pulmonary hypertension produced by a giant left atrial myxoma. The greatest risk is a diagnostic delay due to focus on discarding a pulmonary etiology of dyspnea. Physical examination and early echocardiographic assessment are the keys to avoid overlooking this uncommon pathology.

BACKGROUND: Diastolic dysfunction (DD) can lead to heart failure and higher mortality. Echocardiograms can detect DD but are not indicated for screening in older adults. Our aim was to evaluate the prevalence of DD and the impact of identifying it in seniors. METHODS: We performed screening echocardiograms in 5227 consecutive patients between January 2014 and March 2015 in 36 senior-focused value-based clinics across six states. We determined the presence of the grade of DD and defined stage B grade II/III (asymptomatic) and of stage C grade II/III (symptomatic) DD by the presence or absence of typical HF symptoms...
