INTRODUCTION: Acute peripartum cardiomyopathy complicated by cardiogenic shock is a rare but life-threatening disease. A prolactin fragment is considered causal for the pathogenesis of peripartum cardiomyopathy. This analysis sought to investigate the role of early percutaneous mechanical circulatory support with micro-axial flow-pumps and/or veno-arterial extracorporeal membrane oxygenation in combination with the prolactin inhibitor bromocriptine in refractory cardiogenic shock complicating peripartum cardiomyopathy...

Speckle tracking echocardiography (STE)-derived strain indices are believed to detect early cardiac dysfunction in survivors of childhood cancer and have potential to identify patients who may benefit from early heart failure treatment. However, effects of heart failure treatment on STE-derived strain measurements in this population are unknown. The aim of this study was to assess STE-derived strain measurements in survivors of childhood cancer treated with angiotensin converting enzyme inhibition or receptor blockade (ACEi/ARB)...

BACKGROUND: Type 2 diabetes mellitus (T2DM) greatly increases the risks of cardiovascular disease and heart failure. In particular, left ventricular diastolic dysfunction that develops from the early stages of T2DM is an important factor in the onset and exacerbation of heart failure. The effect of sodium-glucose cotransporter 2 inhibitors on left ventricular diastolic function has not been elucidated. We have performed the first prospective study on the effects of canagliflozin on left ventricular diastolic function in T2DM...

OBJECTIVES: Survival after heart transplantation is steadily improving but primary graft dysfunction (PGD) is still a leading cause of death. Medical management seems useful in mild or moderate PGD, whereas extracorporeal life support (ECLS) could be suggested for severe PGD refractory to conventional treatment. Our aim is to present the results of ECLS for PGD after heart transplantation at a single-centre experience. METHODS: We performed an observational analysis of our local database...

Aims: Increases in left ventricular filling pressure are a fundamental haemodynamic abnormality in heart failure with preserved ejection fraction (HFpEF). However, very little is known regarding how elevated filling pressures cause pulmonary abnormalities or symptoms of dyspnoea. We sought to determine the relationships between simultaneously measured central haemodynamics, symptoms, and lung ventilatory and gas exchange abnormalities during exercise in HFpEF. Methods and results: Subjects with invasively-proven HFpEF (n = 50) and non-cardiac causes of dyspnoea (controls, n = 24) underwent cardiac catheterization at rest and during exercise with simultaneous expired gas analysis...

Left ventricular assist devices (LVADs) have become the standard therapy for patients with end-stage heart failure, and the use of LVADs for long-term support has grown exponentially over the past decade. As the number of LVAD implantations has increased, surgeons have faced more challenging cases, such as those in which the patient has previously undergone a sternotomy. The HeartMate II is one of the most widely implanted LVADs. The standard procedure for HeartMate II implantation is median sternotomy and sewing the outflow graft to the ascending aorta...

Thyrotoxicosis is associated with cardiac dysfunction; more commonly, left ventricular dysfunction. However, in recent years, there have been more cases reported on right ventricular dysfunction, often associated with pulmonary hypertension in patients with thyrotoxicosis. Three cases of thyrotoxicosis associated with right ventricular dysfunction were presented. A total of 25 other cases of thyrotoxicosis associated with right ventricular dysfunction published from 1994 to 2017 were reviewed along with the present 3 cases...

BACKGROUND AND AIMS: Although it is important to analyze the hemodynamic factors related to the right ventricle (RV) after left ventricular assist device (LVAD) implantation, previous studies have focused only on the alteration of the ventricular shape and lack quantitative analysis of the various hemodynamic parameters. Therefore, we quantitatively analyzed various hemodynamic parameters related to the RV under normal, heart failure (HF), and HF incorporated with continuous flow LVAD therapy by using a computational model...

BACKGROUND: Left ventricular assist devices (LVAD) provide a lifesaving bridge to cardiac transplant. Utilization of these devices is increasing in the United States. When a patient undergoes cardiac transplant, the left ventricular device is surgically removed and the driveline is extracted or left tunneled in the subcutaneous tissue. Our group encountered a rare and previously unreported complication of this device: intraperitoneal infiltration of a retained driveline after cardiac transplant causing a small bowel obstruction...

BACKGROUND: Aortic regurgitation (AR) is a valvular disease that can lead to systolic heart failure. Treatment options besides cardiac surgery are limited and consequently severe AR is associated with higher mortality and morbidity when not operated. In this investigation, we examined the effects of a novel cardiac myosin activator, Omecamtiv-mecarbil (OM), in rats with chronic severe AR. METHODS: AR was created by retrograde puncture of the aortic valve leaflets in 20 adults Wistar rats...

The article focuses on current aspects of epidemiology, clinical picture, and diagnostics of patients with chronic heart failure (CHF) associated with preserved left ventricular (LV) systolic function. Heart failure with preserved LV ejection fraction (HFpEF) is shown to be prevalent in a population that accounts for more than a half of all CHF cases. The group at risk for HFpEF consists primarily of older women with arterial hypertension, type 2 diabetes mellitus, obesity, and atrial fibrillation. The article presents algorithms for diagnosis of HFpEF based on classic and tissue Doppler echocardiography and measurement of natriuretic peptides...
