Left Ventricular Hypertrophy Findings on Electrocardiogram Predict Impaired Left Atrial Functions.

Objective: Electrocardiographic left ventricular hypertrophy (ECG LVH) holds significant clinical importance in cardiovascular disease. Pathological processes that lead to left ventricular hypertrophy (LVH) also induce remodeling and impair left atrial (LA) function. Atrial function can be assessed using speckle-tracking echocardiography.

Strain Echocardiographic Evaluation of Myocardial Involvement in Patients with Continuing Chest Pain after COVID-19 Infection.

Background: A new clinical manifestation called post or long coronavirus disease (p/l COVID) has walked into our lives after the acute COVID-19 phase. P/l COVID may lead to myocardial injury with subsequent cardiac problems. Diagnosing these patients quickly and simply has become more important due to the increasing number of patients with p/l COVID.

[A case of occurring hemodynamic deterioration and ST-segment elevation during transcatheter aortic valve implantation].

Transcatheter aortic valve implantation is becoming increasingly popular as an alternative treatment technique for symptomatic patients with severe aortic stenosis, who are at high risk for surgery. However, with this revolutionary treatment modality, some fatal complications have also emerged. One of these fatal complications is the occlusion of the left main coronary artery at the time of procedure.

This study is designed to evaluate the right heart changes by performing echocardiography after trastuzumab treatment in patients with erb-2 breast cancer.

Decline in mean platelet volume in patients with patent foramen ovale undergoing percutaneous closure.

Introduction: The presence of patent foramen ovale (PFO) is considered a possible cause for cryptogenic stroke. The mechanism underlying the ischaemic neurological events in the presence of PFO has not been firmly established. The purpose of this study was to compare: (1) the mean platelet volume levels in PFO patients with and without a cryptogenic stroke, and (2) pre- and post-procedural mean platelet volumes (MPV) in patients undergoing percutaneous PFO closure.

Left ventricular (LV) thrombi usually occur in the presence of impaired LV function, such as in dilated cardiomyopathy, aneurysm or following myocardial infarction. Thrombus formation in a normally functioning LV is extremely rare. We report a patient with LV thrombus formation despite a normal systolic function.
