AIM: To explore the value of cough maneuver (CM) in detecting right-to-left (RLS) during contrast transthoracic echocardiography (cTTE) and its mechanism. METHOD: We enrolled 196 patients with a high level of clinical suspicion of RLS underwent cTTE for RLS detection. Valsalva maneuver (VM) (blowing into a face mask connected to a sphygmomanometer at 40 mm Hg for 10 seconds) and CM were performed to provoke RLS, respectively. A comparison of the two provocative maneuvers in terms of the RLS-detection rate, the degree of RLS, the mobility of septum primum was done...

Unguarded tricuspid orifice is the most extreme of tricuspid valve dysplasia with a very variable natural history. They can tolerate tricuspid regurgitation well, and they become symptomatic only if significant right ventricular dysfunction or atrial fibrillation occurs. Patients with a mild degree of right ventricular dysfunction can survive to adulthood and even reach old age. Surgical treatment is a difficult option due to variable natural history, and surgical results are not too encouraging.

Coronary sinus atrial septal defect (ASD) is a rare congenital cardiac anomaly, which might be difficult to diagnose. In this report, we describe a patient with small secundum ASDs and an associated large coronary sinus ASD, which had been missed at initial evaluation. The diagnosis of coronary sinus ASD was established by using transesophageal echocardiography after percutaneous closure of a small secundum ASD at another center. Patient underwent corrective surgery.

Chronic myeloid leukaemia (CML) is a neoplastic disorder of myeloid cell lines and is a less aggressive disease compared to acute myeloid leukemia (AML). Although cardiovascular complications are not uncommon, intracardiac thrombosis in CML is rarely reported. Herein, we report a case of CML presenting with an intracardiac thrombus attached to the posterior mitral leaflet, and subsequently resulting in peripheral embolization.

BACKGROUND: Estimation of left ventricular filling pressure (LVFP) is the essential part of the echocardiographic workup for exercise intolerance. The ratio of the mitral early filling velocity to the left ventricular global longitudinal strain (E/LVGLS) has emerged as a novel index of LVFP. This study aimed to investigate the relationship between E/LVGLS and exercise capacity. METHODS AND RESULTS: We retrospectively reviewed 90 patients with exertional dyspnea who underwent echocardiography and cardiopulmonary exercise test...

A young patient affected by a lung neoplasm, presented at emergency department with cardiac tamponade, underwent pericardiocentesis with a prompt restoration of hemodynamic stability. An hour later, the patient presented again signs of tamponade, without evidence of fluids in the drainage that was left in pericardial space. The echocardiography revealed an intrapericardial thrombus compressing the right chambers. An emergency pericardiotomy was performed and a large thrombus was removed from the pericardial space; cardiac walls were intact...

BACKGROUND: Dobutamine stress echocardiography (DSE) is a well-established imaging modality used to screen patients with mild-to-moderate risk for coronary artery disease. In heart transplantation recipients, cardiac allograft vasculopathy (CAV) is a common and lethal complication. The use of DSE to detect CAV showed promising results initially, but later studies showed limitation in its use to detect CAV. It is unclear if this cohort of patients derives benefit from DSE. METHODS: We searched PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Embase, and Scopus from inception through March 2018 for studies examining the accuracy of DSE in correlation to coronary angiography (CA) or intravascular ultrasound (IVUS) to detect CAV...

BACKGROUND: A clinically based sudden cardiac death (SCD) risk score has predictive value. Echocardiographic parameters predict SCD. Our aim was to evaluate the effect of adding echocardiographic parameters to the clinical SCD risk score for the prediction of all-cause mortality. METHODS: We conducted a retrospective cohort of screening echocardiograms performed on primary care patients. We calculated the SCD risk score and added the left ventricular (LV) mass index, LV hypertrophy, diastolic dysfunction, and LV ejection fraction (EF)...

A 16-year-old healthy boy visited our department because of a heart murmur. A 12-lead electrocardiogram showed left QRS axis deviation and repolarization abnormalities. Transthoracic echocardiography and a computed tomographic scan revealed a hypertrophied papillary muscle and a discrete ridge arising from the septal wall, causing mid-ventricular obstruction. Doppler echocardiography revealed that the pressure gradient at the obstruction was mild. The patient will be followed up annually, without medication or physical restriction...

AIMS: To examine the associations between diastolic dysfunction indices and long-term risk of all-cause mortality in adults over 23-year follow-up. METHODS AND RESULTS: Participants (n = 2734) of the population-based Tromsø Study of Norway had echocardiography in 1994-1995. Of these 67% were repeated in 2001 and/or 2007-2008. Mortality between 1994 and 2016 was determined by linkage to the national death registry. Cox regression was used to model the hazard of all-cause mortality in relation to left atrial parameters (treated as time-dependent using repeated measurements) adjusted for traditional risk factors and cardiovascular disease...

Kommerell diverticulum (KD) with aberrant left subclavian artery (ALSA) is a rare congenital variation of vascular structure. We reported a case of 3-year-old boy with KD and ALSA, which was preliminarily diagnosed by transthoracic echocardiography and verified by computed tomography angiography (CTA). The patient was treated successfully with KD resection and anastomosed the left subclavian artery directly to the left carotid artery under cardiopulmonary bypass. Our case illustrates that echocardiography and CTA should be used to comprehensively assess all the internal and external cardiac structures in order to determine the appropriate surgical plan...
