Cardiac ECHO in mitral regurgitation

BACKGROUND: Hypertrophic cardiomyopathy (HCM) and Fabry disease (FD) are genetically inherited diseases with left ventricular hypertrophy (LVH) phenotype characteristics that cause adverse cardiac outcomes. OBJECTIVES: To investigate the demographic, clinical, biochemical, electrocardiographic (ECG), and echocardiographic (ECHO) differences between HCM and FD. METHODS: 60 HCM and 40 FD patients were analyzed retrospectively as a subanalysis of the 'LVH-TR study' after excluding patients with atrial fibrillation, pace rhythm, bundle branch blocks, and second and third-degree atrioventricular (AV) blocks...

Optimizing MRI aortic flow quantification is crucial for accurate assessment of valvular disease severity. In this study, we sought to evaluate the accuracy of a novel method of contouring systolic aortic forward flow in comparison to standard contouring methods at various aortic levels. The study included a cohort of patients with native aortic valve (AoV) disease and a small control group referred to cardiac MRI over a 1-year period. Inclusion criteria included aortic flow quantification at aortic valve and one additional level, and no or trace mitral regurgitation (MR) documented both by the MRI AND an echocardiogram done within a year...

Thyrotoxicosis is a clinical condition characterized by inappropriately elevated thyroid hormone levels in the bloodstream, leading to systemic effects on the body. In fact, the thyrotoxic state has tight regulatory control over the cardiovascular system through genomic and non-genomic mechanisms. This study highlights a rare presentation of thyrotoxic cardiomyopathy (TCM), which, to the best of our knowledge, is one of the very few case reports involving heart failure with preserved ejection fraction (HFpEF) and only atrial involvement, compared to the previous literature...

BACKGROUND: Aortic dissection is a critical condition often presenting with acute, severe chest pain and haemodynamic instability. Early diagnosis is essential to mitigate the high mortality risk. Imaging modalities play a pivotal role in diagnosing aortic conditions, but determining the appropriate method can be challenging. CASE DESCRIPTION: We report an asymptomatic 55-year-old female undergoing transthoracic echocardiography (TTE) for mitral and aortic valve regurgitation surveillance...

UNLABELLED: Cardioembolism associated with atrial fibrillation is a major cause of ischemic stroke. Left atrial appendage occlusion in atrial fibrillation patients undergoing cardiac surgery reduces the risk of postoperative stroke. A 78-year-old man with a history of atrial fibrillation and severe mitral regurgitation underwent thoracoscopic mitral valve repair with left atrial appendage clipping and the cryo-maze procedure 4 years previously. He was taking a direct oral anticoagulant for stroke prevention because his atrial fibrillation had recurred...

In patients with significant cardiac valvular disease, intervention with either valve repair or valve replacement may be inevitable. Although valve repair is frequently performed, especially for mitral and tricuspid regurgitation, valve replacement remains common, particularly in adults. Diagnostic methods are often needed to assess the function of the prosthesis. Echocardiography is the first-line method for noninvasive evaluation of prosthetic valve function. The transthoracic approach is complemented with two-dimensional and three-dimensional transesophageal echocardiography for further refinement of valve morphology and function when needed...

OBJECTIVE: To develop breed-specific echocardiographic values for normal Borzoi and to report the prevalence of structural cardiac abnormalities. ANIMALS: 146 clinically healthy, adult Borzoi dogs. METHODS: Cardiac auscultation and standard echocardiograms were performed. Longitudinal follow-up was described in a subset of dogs (n = 25). RESULTS: Most Borzoi were structurally normal (119/146, 81.5%), with breed-specific echocardiographic values generated independently for each sex, as females weighed significantly less than males (30...

OBJECTIVES: A novel transapical beating-heart septal myectomy (TA-BSM) procedure was performed for patients with latent obstruction through the left intercostal incision and without cardiopulmonary bypass. This study aims to demonstrate the experience of the TA-BSM procedure for patients with latent obstruction and compare outcomes to patients with resting obstruction. METHODS: We studied 120 symptomatic hypertrophic obstructive cardiomyopathy patients (33 with latent obstruction and 87 with resting obstruction) who underwent TA-BSM...

Anomalous Left Coronary Artery from the Pulmonary Artery (ALCAPA) typically presents in infancy; however, there are cases of patients who survive the infant period and present later in life. We aimed to characterize patients with late ALCAPA diagnoses and to assess perioperative and functional outcomes. A retrospective chart review of patients who underwent ALCAPA repair between 1996 and 2020 at Boston Children's Hospital was performed. This cohort was divided into early ALCAPA (< 1 year) and late ALCAPA (≥ 1 year) groups...

A 44-year-old man with no known medical history presented with stroke symptoms and was found to have occlusion of the M1 segment of the right middle cerebral artery. Thrombolysis and aspiration thrombectomy were successfully performed. However, in the following hours, he developed a fever and multiple cerebral hemorrhages. Due to a drop in hemoglobin post-angiography, an abdominopelvic CT was performed, revealing extensive splenic and renal infarctions. The patient was diagnosed with infective endocarditis (IE) with mitral and aortic vegetations and severe aortic regurgitation...

Hemoptysis is a common presenting symptom in the clinical setting. The most frequent causes of non-life-threatening hemoptysis, which usually originates from the pulmonary arterial circulation, include pulmonary pathologies such as infections, inflammatory airway diseases, and bronchial neoplasms. Hemoptysis occurring only after sexual intercourse, however, is a rare phenomenon. Most of the reported cases have resulted from an underlying cardiac pathology that is predisposed to acute cardiovascular decompensation, a sharp increase in pulmonary capillary pressures, and pulmonary capillary rupture during intercourse...

INTRODUCTION: Acute mitral regurgitation (MR) due to papillary muscle rupture (PMR) is a rare but lethal mechanical complication of acute myocardial infarction (MI). The treatment of patients with post-MI PMR, especially those with cardiogenic shock, presents great challenges due to the high surgical risk. PATIENT CONCERNS: We report an 80-year-old woman with a history of hypertension and diabetes mellitus, presented with chest pain. Despite an early percutaneous coronary intervention and transfer to the intensive care unit, her general condition and hemodynamic parameters continued to deteriorate rapidly...

BACKGROUND: Transesophageal echocardiography (TEE) can reliably detect left atrial (LA) and LA appendage (LAA) thrombus in patients with atrial fibrillation (AF) before electrical cardioversion (ECV). However, evaluating cardiac and valve function pre-ECV can be challenging due to the increased and irregular heart rate. Additionally, post-ECV atrial stunning increases the risk of thrombosis. Therefore, post-ECV TEE may allow for useful appendage, ventricular and valve function assessment...

OBJECTIVE: We sought to develop a risk prediction model for pre-discharge major mitral valve (MV) residual lesions or unplanned MV reinterventions following congenital MV repair. METHODS: Patients that underwent congenital MV repair (excluding primary repair, but including secondary repair, of canal-type defects) at a single institution from 01/2000-12/2020 and survived to discharge were retrospectively reviewed. The primary outcome was major MV residua (mean gradient >6 mmHg or ≥moderate regurgitation on the discharge echocardiogram) or pre-discharge unplanned MV reintervention...

BACKGROUND: Ivabradine, a medical treatment for heart failure (HF), reduces heart rate (HR) and prolongs diastolic perfusion time. It is frequently prescribed to patients with HF who have a suboptimal response or intolerance to beta-blockers. Degenerative mitral regurgitation (MR) is a valvular heart disease often associated with the development of HF and atrial fibrillation (AF). However, studies comparing the effects of ivabradine and beta-blockers on MR are lacking. Therefore, this study aimed to explore the potential therapeutic effects of ivabradine and carvedilol on MR using a rat model...

OBJECTIVE: To summarize echocardiographic characteristics of the anatomy and hemodynamic and clinical outcomes in fetuses with isolated pulmonary stenosis (PS) or pulmonary atresia with intact ventricular septum (PA/IVS). METHODS: This was a single-center retrospective study of fetuses with isolated PS or PA/IVS. Echocardiographic variables and clinical outcomes after delivery were evaluated and compared. RESULTS: Between 2016 and 2021, 115 livebirths with isolated PS or PA/IVS were included...

BACKGROUND: Early diagnosis of significant valvular heart disease (VHD) enables appropriate implementation of the best therapeutic strategy and follow-up. Cardiac auscultation remains suboptimal in early detection of VHD. The aim of this study was to evaluate the utility of point-of-care ultrasound (POCUS) for early detection of VHD and its severity. METHODS: All consecutive patients with VHD who did not have a standard echocardiogram prior to first outpatient cardiology consultation underwent history and physical examination followed by POCUS study by an experienced physician in a general cardiology clinic from June 2017 to August 2022 at our institution...

INTRODUCTION: One indication for the implantation of a cardioverter-defibrillator is a reduction in the left ventricular ejection fraction (LVEF) ≤ 35%. However, in certain patients following an acute myocardial infarction (AMI) a gradual improvement in LVEF has been observed. The factors determining this increase in LVEF have not been conclusively determined. AIM: To ascertain the independent predictors associated with the improvement of LVEF in patients following AMI who underwent invasive treatment, while observing their progress over a 6-month follow-up period...

INTRODUCTION: Surgical intervention is an important treatment modality for advanced rheumatic heart disease (RHD). This study aimed to describe patient characteristics and outcomes from cardiac surgery for RHD in patients referred to the only tertiary paediatric hospital in Western Australia. METHODS: An analysis of patient characteristics and cardiac surgery outcomes in patients with RHD was undertaken, using data from clinical cardiac databases, medical notes, and correspondence from rural outreach clinics...

Giant right atrium (RA) is a rare finding in adults. We report a case of a 53-year-old female with rheumatic heart disease (RHD) previously submitted to two mitral valve replacements. She presented at the emergency room with signs of heart failure. Image studies revealed gross cardiomegaly. Transthoracic echocardiogram showed torrential tricuspid regurgitation, with right chambers enlargement. At chest tomography, the estimated right atrium volume was 1,200 mL. The patient was treated with intravenous diuretics and multiple paracentesis, as well as referred to heart transplantation...
