Tricuspid regurgitation (TR) is a common valvular pathology, estimated to affect 1.6 million people in the United States alone. Even though guidelines recommend either medical therapy or surgical treatment for TR, the misconception of TR as a benign disease along with the high mortality rates of surgical intervention led to undertreating this disease and commonly describing it as a "forgotten" valve.

Methods: A literature search was conducted for randomized controlled trials. Our search took place in three major databases.
Electrocardiogram (ECG) still remains a very useful diagnostic method in modern cardiology. Its broad availability, noninvasiveness and good sensitivity explain why it plays a capital role in the very beginning of the process of diagnosis for every patient, with or without cardiac-related complaints. For the practitioner, good training in ECG interpretation is mandatory.

Left ventricular (LV) dysfunction and cardiac deformation measured by speckle tracking echocardiography seem to play an important prognostic role in several different specific populations.
Objective: Τhe prognostic value of strain analysis measurements, including the novel diastolic parameters such as left atrial (LA) strain, in patients with end-stage renal disease on dialysis (stage 5 CKD).
A 67-year-old male presented with non-ST-segment elevation myocardial infarction. Angiography showed severe restenosis within the previously (before 2 years) implanted 2 stents (3 x 24 mm) in the right coronary artery. Severe calcification was evident angiographically and after multiple dilations with noncompliant balloons, the focal underexpansion of the stent remained.

Echocardiography and left ventriculography were indicative of takotsubo cardiomyopathy, probably attributed to abrupt discontinuation of buprenorphine. Opioid withdrawal leads to sympathetic hyperactivity and increased catecholamine release, which in our case triggered takotsubo cardiomyopathy presentation.

This study sought to determine priority issues facing men with PCa, barriers and enablers to accessing care and whether health professionals (HPs) and men would support the inclusion of a patient-reported outcome (PRO) comparator tool.
Methods: We conducted four online focus groups with HPs recruited from healthcare services in Victoria, followed by seven online codesign workshops with men with PCa, recruited through the Victorian Prostate Cancer Outcomes Registry, Prostate Cancer Foundation Australia and the Cancer Council Victoria.

Sickle cell disease (SCD) is an inherited monogenic hemoglobinopathy characterized by formation of sickle erythrocytes under conditions of deoxygenation. Sickle erythrocytes can lead to thrombus formation and vaso-occlusive episodes that may result in hemolytic anemia, pain crisis and multiple organ damage. Moreover, SCD is characterized by endothelial damage, increased inflammatory response, platelet activation and aggravation, and activation of both the intrinsic and the extrinsic coagulation pathways.

Objectives: We compared the long-term outcomes of percutaneous coronary intervention with second-generation drug-eluting stents (PCI-DES) and coronary artery bypass graft surgery (CABG) with the left internal mammary artery in stable angina patients with isolated single-vessel proximal left anterior descending artery (pLAD) disease.
Background: Long-term outcomes of second-generation PCI-DES and CABG in isolated pLAD lesions have not been extensively studied.
Methods: We included 631 PCI-DES patients and 379 CABG patients.
Vortex formation time (VFT) is a dimensionless index used to quantify duration of vortex ring formation during diastole. We sought to investigate the effect of pharmaceutical stress on VFT in patients evaluated for ischemia. For this purpose, a standard dobutamine stress echo (DSE) protocol was performed in 50 consecutive patients, and VFT was calculated at rest and at peak.

The purpose of the study was to assess whether in patients with "halo-sign", defined as increased tissue thickness at the edge of the ASD rims, there is an agreement between 3D TEE and 2D balloon stretched diameter aiming to avoidance of balloon sizing. Forty consecutive patients who underwent closure of a single, without complex anatomy ASD were included.

To investigate the hemodynamic profile of patients without acute decompensated heart failure and left ventricular ejection fraction >50% referred for elective left and right heart catheterization and to correlate left and right filling pressures, stroke volume and arterial blood pressure to renal function parameters. Subsequently, we tested the hypothesis that right ventricle and left ventricle hemodynamic parameters can predict all-cause mortality in our non-HF subjects.

The rapid advancement of imaging techniques, including computed tomography, magnetic resonance imaging, intravascular ultrasound and optical coherence tomography, have provided us with a wealth of new information on the subject. Anomalous origin of a coronary artery from the contralateral sinus is the anomaly most frequently associated with sudden cardiac death, in particular if the anomalous coronary artery has a course between the aorta and the pulmonary artery.

We aimed to develop a valid, relevant and feasible set of core QIs to measure quality of radiotherapy care in men with prostate cancer.
Materials And Methods: We used a RAND-modified Delphi process to select QIs that were regarded as both important and feasible measures of quality radiotherapy care.
The aim of this study was to evaluate in an experimental model of aortic valve (AV) stenosis the effectiveness of zoledronate on the inhibition of calcification. Sixteen New Zealand rabbits were placed on vitamin D-enriched diet for 3 weeks. All animals underwent PET/CT at baseline and before euthanasia to assess calcification.

The aim of this study was to investigate factors associated with physical activity levels in patients with VLUs. Data from 2016 to 2017 Aspirin for Venous Leg Ulcer cohort study were analysed for the present study.

Although often considered as solely arrhythmic in nature, current evidence has established that atrial myopathy constitutes both the substrate and the outcome of atrial fibrillation, thus initiating a vicious, self-perpetuating cycle. This myopathy is triggered by stress-induced (including pressure/volume overload, inflammation, oxidative stress) responses of atrial tissue, which in the long term become maladaptive, and combine elements of both structural, especially fibrosis, and electrical remodeling, with contemporary approaches yielding potentially useful biomarkers of these processes.

Subjects/methods: in 2006-2009, 1000 consecutive patients hospitalized at First Cardiology Clinic of Athens with ACS diagnosis were enrolled in the study.
Aortic valve stenosis is one of the most common valvular heart disorders and the prevalence will rise as the population ages. Once symptomatic patients with aortic valve stenosis tend to fare worse with high mortality rates. Aortic valve replacement is indicated in these patients and besides the standard surgical replacement, a less invasive approach, transcatheter aortic valve implantation, has gained momentum and has showed promising and solid results in patients with high surgical risk.
