OBJECTIVES: This study evaluates the impact of untreated preoperative severe mitral valve regurgitation (MR) on outcomes after left ventricular assist device (LVAD) implantation. METHODS: Of the 234 patients who received LVAD therapy in our centre during a 6-year period, we selected those who had echocardiographic images of good quality and excluded those who underwent mitral valve replacement prior to or mitral valve repair during LVAD placement. The 128 patients selected were divided into 2 groups: Group A with severe MR (n = 65) and Group B with none to moderate MR (n = 63, 28 with moderate MR)...

BACKGROUND: The clinical relevance of non-invasively derived pulmonary arterial pressure (PAP) by Doppler echocardiography (DE) has been questioned in the past. However, transthoracic echocardiography is used as a cornerstone examination for patients with dyspnea and suspected pulmonary hypertension (PH). This study aimed to evaluate the prognostic value of non-invasive assessed PAP in a large population of patients with known or suspected cardiopulmonary disease. METHODS: The analyses are based on data of patients of a tertiary cardiology center that received right heart catheterization (RHC) as well as non-invasively assessed PAP by DE within five days, and includes serological and clinical parameters in a retrospective follow-up for up to eight years...

Left ventricular mass index (LVMI) increase has been described in hypertension (HTN), but less is known about its association with type 2 diabetes (T2DM). As these conditions frequently co-exist, we investigated the association of T2DM, HTN and both with echocardiographic parameters, and hypothesized that patients with both had highest LVMI, followed by patients with only T2DM or HTN. Study population included 101 T2DM patients, 62 patients with HTN and no T2DM, and 76 patients with T2DM and HTN, excluded for ischemic heart disease...

A 52-year old female was admitted with complaints of palpitations for two years. The transthoracic echocardiography and electrocardiogram were both normal at the time of admission. We performed an electrophysiology study where the baseline intervals were in normal range. During burst atrial pacing we observed HV prolongation (HV = 80 ms) and infra-Hisian block.

Infective endocarditis (IE) is an infectious disease that affects the endothelium of the large intrathoracic vessels, heart valves, and intra-cardiac foreign body material. A 20-year-old woman was admitted to the cardiology department with complaints of fever and palpitations. Transthoracic echocardiography revealed a bicuspid aortic valve, aortic root enlargement, and aortic coarctation. Transesophageal echocardiography revealed a bicuspid aortic valve, but there was no vegetation. Methicillin-sensitive Staphylococcus aureus was identified on a blood culture...

OBJECTIVE: Hypertension is a significant risk factor for atrial fibrillation (AF). The role of pulmonary vein (PV) remodeling in the mechanistic association between hypertension and AF is not definitive. In this study, we aimed to identify changes in the electrophysiology and histology in PVs in two-kidney, one-clip (2K1C) hypertensive rats. METHODS: Fifty male Sprague-Dawley rats were classified into the 2K1C and sham-operated groups. The systolic blood pressure was measured every 2 weeks...

Quadricuspid aortic valve (QAV) is a rare congenital anomaly frequently associated with other anomalies particularly coronary anomalies. It may be detected on transthoracic or transesophageal echocardiography. We present here a case report of a 27-year-old male patient with a QAV, the valve being regurgitant and requiring aortic valve replacement. It has been reported as isolated case reports in the literature and various theories exist to the development of QAV. The diagnosis requires a high degree of suspicion and a detailed assessment, and if asymptomatic, then patients need to be carefully followed up for the development of aortic regurgitation...

Left atrial fibroma as a benign tumor is an exceedingly rare left atrial mass. It has various clinical signs and symptoms and sometimes leads to serious complications such as lethal arrhythmia and death. We report a case of right atrial fibroma in a 40-year-old male who presented with dyspnea and atrial fibrillation. Transthoracic echocardiography revealed a large sessile mass attached to interatrial septum near the coronary sinus valve in the right atrium. The patient underwent surgical resection of tumor through the right atrium...

Drug-induced (Group 1) pulmonary hypertension (PH) is an important subgroup of PH involving dasatinib as a likely related agent, which is a second-generation tyrosine kinase inhibitor (TKI), that is used in the treatment of chronic myeloid leukemia (CML). The mechanism of dasatinib-induced pulmonary arterial hypertension (PAH) is unclear. However, the occurence of PAH at a late onset in CML patients suggests a chronic pathological mechanism with an insidious onset rather than an acute inflammatory or cardiac etiology...

Objectives: The current management of coronary artery disease (CAD) relies on three major therapeutic options, namely medication, percutaneous coronary intervention (PCI), and coronary artery bypass grafting (CABG). However, severe CAD that is not indicated for PCI or CABG still bears a poor prognosis due to the lack of effective treatments. In 2006, extracorporeal cardiac shock wave (SW) therapy reported on human for the first time. This treatment resulted in better myocardial perfusion as evaluated by dipyridamole stress thallium scintigraphy, angina symptoms, and exercise tolerance...

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 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...

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...
