BACKGROUND: Postresuscitation myocardial dysfunction (PRMD) can develop after successful resuscitation from cardiac arrest. However, echocardiographic patterns of PRMD remain unknown. This study aimed to investigate PRMD manifestations with serial echocardiography during the post-cardiac arrest period. METHODS: We enrolled non-traumatic out-of-hospital cardiac arrest patients older than 19 years who underwent successful cardiopulmonary resuscitation (CPR). We excluded patients with myocardial infarction or pre-existing cardiac disease, including heart failure or myocardial disease...

BACKGROUND: This study aimed to investigate the mechanisms of acute changes in functional mitral regurgitation (FMR) by preload alterations. METHODS: Twenty-two consecutive patients with left ventricular ejection fraction <40% and at least mild FMR underwent transthoracic echocardiography. Passive leg lifting and sublingual administration of nitroglycerin were performed to alter preload. Mitral regurgitant volume (MRV) was assessed using the Doppler method. RESULTS: MRV changed in parallel with preload alterations...

BACKGROUND AND OBJECTIVE: In interstitial lung disease (ILD), pulmonary hypertension (PH) is a major adverse prognostic determinant. Transthoracic echocardiography (TTE) is the most widely used tool when screening for PH, although discordance between TTE and right heart catheter (RHC) measured pulmonary haemodynamics is increasingly recognized. We evaluated the predictive utility of the updated European Society of Cardiology/European Respiratory Society (ESC/ERS) TTE screening recommendations against RHC testing in a large, well-characterized ILD cohort...

4D flow MRI is an emerging technique that allows quantification of 3D blood flow in vivo. However, comparisons with methods of blood velocity quantification used in clinical routine are sparse. Therefore, we compared velocity quantification using 4D flow MRI with transthoracic and transesophageal echocardiography at the mitral and aortic valves and the aorta. Forty-eight stroke patients (age 67.3 ± 15.0 years) were examined by 4D flow MRI. Blood flow velocities were assessed using standardized 2D analysis planes positioned in the mitral valve (MV), aortic valve (AV), ascending aorta (AAo), and descending aorta (DAo) and were compared with echocardiography...

Large intracavitary masses such as those occupying most of a cardiac chamber and obstructing blood flow are not routinely encountered in clinical practice. The differential diagnosis includes neoplastic as well as nonneoplastic causes. Primary cardiac tumors by themselves are uncommon. We hereby report a rare case of a middle-aged female presenting with New York Heart Association Class III symptoms, whose transthoracic echocardiogram revealed a huge mass in right-sided chambers with a novel double ball valve type movement...

CLINICAL INTRODUCTION: A 26-year-old man with an unremarkable medical history sensed a momentary retrosternal 'pop' followed by overwhelming dyspnoea, without reporting any prodromal symptoms. At the emergency department, he had a significant tachycardia (170 bpm) and an extreme low diastolic blood pressure (<30 mm Hg). A loud, harsh and continuous murmur could be maximally auscultated at the right lower sternal border. ECG revealed global ST depression with ST elevation in lead aVR...

A 42-year-old female patient was referred our clinic for investigation of a history of acute retinal artery occlusion. Transthoracic echocardiography showed a cyst-like, mobile formation on posterior mitral valve leaflet. 2D and real time 3D transesophageal echocardiography showed a flexible circular mobile structure which was attached to posterior mitral valve leaflet. Echocardiographic appearance and morphological characteristics were suggestive of accessory mitral valve tissue.

Cardiac myxomas are benign neoplasm of the heart with an incidence of 0.3%. Glandular cardiac myxomas are very rare and accounts for less than 3% of all cardiac myxomas. Here, we report a case of familial glandular cardiac myxoma in a 35 year old male who complained of exertional dyspneoa and weakness of right side of body on clinical presentation. Associated features of Carney's complex were not present. Family history revealed presence of cardiac myxoma in younger brother and sister. Transthoracic echocardiography detected biatrial myxoma...

Purulent pericarditis has become rare since the advent of antibiotics. Among the involved germs, S. pneumoniae remains the most implicated pathogen to evoke in principle, especially that prescription of systematic antibiotics for any febrile condition can considerably mask the clinical picture. A 36-year-old pregnant woman was visiting the emergency department for dyspnea and flu-like syndrom that had been going on for a week. The chest X-ray showed a white lung on the left and the transthoracic ultrasound revealed a pericardial effusion, resulting in pericardial drainage and pleural puncture that allows the evacuation of a purulent fluid...

A patient with a history of lung adenocarcinoma was admitted because of palpitation. Transthoracic echocardiogram revealed a mass (74×42 mm) in the right ventricle. Computed tomography showed a tumor lesion in the right ventricular cavity but no other distant metastasis. Coronary angiography revealed well-developed small branches to the tumor. After right heart catheterization, a pathological analysis of a tumor biopsy demonstrated adenocarcinoma. We diagnosed the patient with right ventricular metastasis of lung cancer...

BACKGROUND: Heart failure with preserved ejection fraction (HFpEF) is a poorly characterized condition. We aimed to phenotype patients with HFpEF using multiparametric stress cardiovascular magnetic resonance imaging (CMR) and to assess the relationship to clinical outcomes. METHODS: One hundred and fifty four patients (51% male, mean age 72 ± 10 years) with a diagnosis of HFpEF underwent transthoracic echocardiography and CMR during a single study visit. The CMR protocol comprised cine, stress/rest perfusion and late gadolinium enhancement imaging on a 3T scanner...

Advances in medical diagnosis reveal that coronary artery aneurysms (CAAs) may develop in several clinical scenarios and manifest variable symptoms, imaging appearances, and outcomes. Aneurysms are pathologically classified into three groups: atherosclerotic, inflammatory, and noninflammatory. The last category is associated with congenital, inherited, and connective tissue disorders. Overlap exists among the groups, because secondary atherosclerotic change may be present in an aneurysm of any cause. Atherosclerosis is the most common cause of CAAs in adults, and inflammation is considered the underlying mechanism...

Background: Repeat surgery and the percutaneous approach (transcatheter closure (TCC)) have been used for the management of postoperative left-to-right shunts. In this study, we described our 15 years of experience in treating postoperative left-to-right shunts with these two approaches. Methods: From February 2002 to February 2017, 50 patients with residual left-to-right shunts, following cardiac surgery, were treated using TCC or repeat surgery. Clinical examination, standard 12-lead electrocardiography, chest X-ray, and a transthoracic echocardiogram were performed before hospital discharge and at all follow-ups...

Aims: We assessed the geometry of transcatheter heart valve (THV) and valve function associated with SAPIEN 3 implantation in patients with bicuspid aortic valve (BAV) stenosis. Methods and results: We included 280 consecutive patients who had a contrast computed tomography (CT) before and after transcatheter aortic valve implantation (TAVI) in our institution. Each THV was assessed by CT at five cross-sectional levels: inflow, annulus, mid, sinus, and outflow. The geometry of THV was assessed for eccentricity (1 - minimum diameter/maximum diameter) and expansion (CT derived external valve area/nominal external valve area)...

We describe a strategy aimed at maximizing the safety and minimizing the thrombogenicity of central venous lines for neonates with congenital heart defects. Our method involves the use of a tunneled technique to place a 4.2 Fr single-lumen (Broviac) catheter in the subpericardial space, with minimal intravascular course and a tip placed in the lower right atrium. Using this technique, we potentially eliminated the requirement for percutaneous placement of central venous lines postoperatively as well as potentially decreased the risk of intrapericardial bleeding associated with transthoracic lines...
