BACKGROUND: Handheld echocardiography (HHE) is concordant with standard transthoracic echocardiography (TTE) in a variety of settings but has not been thoroughly compared to traditional TTE in patients with acute myocardial infarction (AMI). HYPOTHESIS: Completed by experienced operators, HHE provides accurate diagnostic capabilities compared with standard TTE in AMI patients. METHODS: This study prospectively enrolled patients admitted to the coronary care unit with AMI...

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...

The term pulmonary hypertension refers to a serious condition characterised by high pulmonary vascular pressure, mainly as a consequence of various cardiac and respiratory diseases. Current clinical classification of pulmonary hypertension considers five distinct groups. Transthoracic echocardiography represents the first and most important noninvasive screening tool for estimating the probability of pulmonary hypertension. The diagnostic approach to pulmonary hypertension is supported by a proposed algorithm, which identifies the underlying cause...

In 1994, the original Duke criteria introduced the usefulness of echocardiography for the diagnosis of definitive infective endocarditis (IE). Recently, the European Society of Cardiology (ESC) highlighted the need of complementary imaging to support the diagnosis of embolic events and cardiac involvement when echocardiography findings are negative or doubtful. We decided to study the usefulness of transthoracic and transesophageal echocardiography (TTE/TEE) for the diagnosis of definitive IE in patients who already benefited from complementary investigations...

The mechanism of re-expansion pulmonary oedema (Re-PE) is unclear. There are multiple variables in play when evaluating the response to evacuation of pleural fluid. We present an educational case of a critically ill patient admitted for respiratory failure who was fully dependent on ventricular pacing set at a constant rate throughout the episode of Re-PE. The transthoracic echocardiography (TTE) showed an ejection fraction of 38%, moderate mitral regurgitation (MR), mildly dilated right ventricle and moderate pulmonary hypertension...

BACKGROUND: Signs of hypovolaemia are frequent in the postoperative period, but not all patients need or respond to fluid administration. An increase in cardiac output (CO) after passive leg raising (PLR) has been demonstrated to be useful as a volume response predictor in non-surgical, spontaneously breathing patients. OBJECTIVE: The objective of this study was to evaluate the accuracy of transthoracic echocardiography after PLR to predict fluid responsiveness in post-surgical patients...

The aim of this study was to evaluate the association between thyroid hormone levels, pulmonary hypertension (PH), and pulmonary artery systolic pressure (PASP) in euthyroid patients with coronary artery disease (CAD). A cross-sectional study was conducted in individuals who underwent coronary angiography and were diagnosed as CAD from March 2013 to November 2013. 811 subjects (185 women and 626 men) were included in this study. PASP was measured by transthoracic Doppler echocardiography. 86 patients were diagnosed as PH and had significantly higher free thyroxine (FT4) levels than those without PH...

BACKGROUND: Epicardial fat thickness (EFT) is associated with increased cardio metabolic risk. Recent studies have suggested that there is a strong relationship between diabetes and EFT. Although the relationship between EFT and coronary artery disease (CAD) is well known, the possible impact of diabetes on the relationship between EFT and extent and complexity of CAD was not fully investigated. AIM: We aimed to investigate the relationship between EFT and extent and complexity of CAD in patients with non-ST elevation myocardial infarction (NSTEMI) with and without diabetes...

A sinus of Valsalva aneurysm is a rare malformation of the aortic root that can fistulize to another cardiac structure such as the right atrium. Although transthoracic echocardiography and computed tomography angiography have demonstrated utility for the diagnosis of a sinus of Valsalva-to-right atrial fistula, there are few cases where a misdiagnosis may occur. Intraoperative transesophageal echocardiography may be an essential imaging tool for the diagnosis and management of incidental findings such as a sinus of Valsalva-to-right atrial fistula during cardiac surgery and should be used routinely...

Although transcatheter arrhythmia ablation (TCA) has been performed in children for over two decades, guidelines for routine use of post-ablation transthoracic echocardiography (TTE) are absent. We sought to determine the efficacy of TTE after apparently uneventful TCA procedures in detecting adverse findings and identify predisposing factors. A retrospective review of clinical and procedural data on patients who underwent TCA for supraventricular arrhythmias from 2000 to 2015 was performed. Pre- and post-ablation TTE data were reviewed...

Alkaptonuric ochronosis is a rare cause of aortic valve stenosis. We report the case of a 61-year-old female patient with alkaptonuria who presented to our institute with the clinical picture of severe aortic valve stenosis, which was confirmed by transthoracic echocardiography. On aortotomy, she was noted to have an impressive black discoloration of ascending aorta and the aortic root complex involving the aortic valve leaflets. She underwent an uneventful aortic valve replacement. She was discharged home 10 days postoperatively...

BACKGROUND: Frequent premature ventricular complexes (PVC) are related to reversible tachycardia-induced cardiomyopathy. However, the role of arrhythmia burden on the outcome of the catheter ablation has not been fully recognised. AIM: The aim of this study was to assess the effect of catheter ablation and PVC burden in patients with and without structural heart disease (SHD) on left ventricular ejection fraction (LVEF). METHODS: Transthoracic echocardiography was done before and six months after radiofrequency catheter ablation in 109 consecutive patients (61 men, age 55 ± 17 years) with frequent PVCs...

BACKGROUND: Ischaemic mitral regurgitation (IMR) is associated with adverse prognosis after myocardial infarction (MI) as a result of left ventricular remodelling and geometric deformation of the mitral apparatus (MA). AIM: The aim of this study was to assess MA from anatomically correct imaging planes in acute inferoposterior MI and IMR. METHODS: Ninety-three patients with no structural cardiac valve abnormalities and the first acute inferoposterior MI were prospectively enrolled into the study...

ABSTARCT Genome-wide association studies pinpointed common variants in or near the MTNR1B gene encoding MT2 melatonin receptor to be strongly associated with fasting glucose levels. IRS2 gene polymorphisms impact insulin resistance and epicardial fat (EF) thickness, which in turn is correlated with visceral adiposity, cognitive ability and risk for metabolic plus cardiovascular disease. We aimed to discover the interactions between MTNR1B and IRS2 gene polymorphisms, insulin sensitivity, EF thickness and cognitive performance in the elderly...

The tricuspid valve (TV), although occasionally considered "neglected" is the subject of renewed and increasing interest. Factors include an awareness that tricuspid value dysfunction is influential in patient outcomes, an improving understanding of valve anatomy and function and evolving techniques available to address tricuspid regurgitation. Tricuspid regurgitation (TR) can be classified as being due to primary diseases of the valve or functional in nature, with the majority being functional. Whilst it was previously believed that such functional TR, resulting from left sided disease, would resolve after correction of the underlying pathology this is now known not to be true...

BACKGROUND: Left ventricular diastolic dysfunction is associated with mortality outcomes in severe sepsis and septic shock. There are ongoing issues with diagnosing diastolic dysfunction in this cohort, partly owing to the poor applicability of traditional parameters in the hyperdynamic circulation. In this feasibility study, we sought to assess the utility of a novel parameter (septal e'/s') to identify diastolic dysfunction in patients with severe sepsis and septic shock who had normal systolic function against the 2016 American Society Echocardiography and European Association of Cardiovascular Imaging (ASE/EACI) guidelines on diastolic dysfunction...

BACKGROUND: Electrical cardiometry (EC) is an impedance-based monitoring that provides noninvasive cardiac output (CO) assessment. Through comparison to transthoracic echocardiography (Echo), the accuracy of EC has been verified. However, left-to-right patent ductus arteriosus (PDA) shunting is a concern because PDA shunts aortic flow to the pulmonary artery and may interfere with EC in measuring CO. OBJECTIVE: To determine the agreement between EC and Echo in preterm infants with a hemodynamically significant PDA (hsPDA)...

Congenital coronary artery anomalies as a whole are uncommon. Abnormal origin of the left coronary artery from the pulmonary artery (ALCAPA) is probably the most common congenital coronary defect. An overwhelming majority of the patients with untreated ALCAPA do not survive to adulthood. As yet, there is no consensus on the management of adults with ALCAPA. We describe a patient with breast malignancy and incidentally detected ALCAPA; primacy was given to treatment of the oncologic condition as a first step...

We present the case of a 65-year-old male who presented with stable angina and dyspnea on exertion. His initial workup yielded a positive treadmill stress test for reversible apical ischemia, and transthoracic echocardiogram demonstrated impaired systolic function. Cardiac catheterization was then performed, revealing severe atherosclerotic disease including multiple coronary artery aneurysms. As a result, the patient was advised to and subsequently underwent a coronary artery bypass graft. This case highlights the presence of multiple coronary artery aneurysms and the ability to appreciate these pathologic findings on multiple imaging modalities, including coronary angiogram, transesophageal echocardiography, and direct visualization through the surgical field...

BACKGROUND: Better survival for overweight and obese patients after ST-segment-elevation myocardial infarction (STEMI) has been demonstrated. The association between body mass index (BMI), outcome, and left ventricular (LV) structure and function after STEMI, including LV longitudinal strain (global longitudinal strain), was evaluated. METHODS AND RESULTS: First patients with STEMI undergoing primary percutaneous coronary intervention (n=1604; mean age, 61±12 years; 75% men) had BMI measured on admission, and 2-dimensional transthoracic echocardiography performed within 48 hours...
