OBJECTIVES: Right ventricular (RV) failure complicating left ventricular assist device implantation is associated with increased mortality. Despite a lack of supporting evidence, venoarterial extracorporeal membrane oxygenation (ECMO) support is increasingly being used as an alternative to traditional temporary RV support. We report our institutional experience with ECMO-facilitated RV support after left ventricular assist device implantation. METHODS: We retrospectively reviewed the concept of temporary ECMO support for perioperative RV failure in 32 consecutive left ventricular assist device (mean age 52 ± 14 years; male 84...

Although improvement in cardiac output and hemodynamic parameters is routinely demonstrated in patients implanted with continuous-flow left ventricular assist devices (CF-LVADs), improvement in exercise capacity is inconsistently seen. Our purpose was to determine whether native cardiac factors, LVAD factors, or comorbid factors were associated with lack of improvement. Review of all patients undergoing preimplant cardiopulmonary exercise testing (CPET) and CPET on LVAD therapy at one institution was performed between 2007 and 2014 (n = 49)...

Simple mechanical reperfusion (SMR) is defined as reperfusion achieved after wire insertion at the occluded infarct-related artery in primary angioplasty. The determinants and prognostic implications of SMR and its relationship with the histopathology of the rescued thrombus were evaluated in 601 patients with acute myocardial infarction showing ST elevation and pre-procedural total occlusion of the infarct-related artery (TIMI flow 0). Two groups were considered according to the presence of SMR, defined as the visualization of contrast material after crossing the occlusion with the guide wire...

BACKGROUND: Takotsubo cardiomyopathy (TCM) is a form of stress-induced cardiomyopathy featured by the dilatation of the apex of the left ventricle during systole. Whereas the pathogenesis of this disorder is not well understood, it usually occurs after an emotional or physical stress such as acute asthma, surgery, chemotherapy, and stroke. However, its occurrence in ileus patients is rarely reported. We hereby report probably the first case of TCM after ileus in the literature and discuss its implications...

Pulmonary arterial hypertension (PAH) is a serious pulmonary vascular disease. The changes in the structure, function and metabolism of endothelial cells are some of the important features of PAH. Previous studies have demonstrated that the mevalonate pathway is important in cardiovascular remodeling. However, whether the mevalonate pathway is involved in the development of PAH remains to be elucidated. The present study aimed to investigate the expression pattern of mevalonate pathway-related enzymes in monocrotaline (MCT)-induced PAH...

Although extensively used for the study of left ventricular function, limited experience exists with the isolated heart model in the evaluation of right ventricular (RV) function. In particular, no published experience exists with this tool in sugen/hypoxia-induced pulmonary hypertension (SuHx-PH), a frequently used model of severe and progressive PH We sought to characterize markers of RV contractile and diastolic function in SuHx-PH and to establish their relationship with markers of maladaptive RV remodeling...

Ikuo Fukuda, Kazuyuki Daitoku
Acute pulmonary thromboembolism is a catastrophic event, especially for hospitalized patients. The prognosis of pulmonary thromboembolism depends on the degree of pulmonary arterial occlusion. The mortality of massive pulmonary embolism is reportedly as high as 25% without cardiopulmonary arrest and 65% with cardiopulmonary arrest. In patients with unstable hemodynamics due to pulmonary thromboembolism, surgical pulmonary embolectomy is indicated for patients with a contraindication to thrombolysis, failed catheter therapy, or failed thrombolysis...

BACKGROUND: Heart failure (HF) is a major cause of cardiovascular admissions and hypertensive heart failure (HHF) is the most common cause of HF admissions in sub-Saharan Africa, Nigeria inclusive. Right ventricular (RV) dysfunction is being increasingly recognized in HF and found to be an independent predictor of adverse outcomes in HF. This study aimed to determine the prevalence of RV systolic dysfunction in HHF by several echocardiographic parameters. METHODOLOGY: One hundred subjects with HHF were recruited consecutively into the study along with 50 age and sex-matched controls...

INTRODUCTION: Cardiac resynchronization therapy (CRT) using biventricular pacing (BVP) is effective in patients with heart failure, bundle branch block (BBB) or right ventricular pacing. Permanent His bundle pacing (HBP) has been reported as an alternative option for CRT. OBJECTIVE: The aim of the study was to assess the feasibility and outcomes of HBP in CRT eligible or failed patients. METHODS: HBP was attempted as a rescue strategy in patients with failed LV lead or non-response to BVP (Group I); or as a primary strategy in patients with AV block, BBB, or high ventricular pacing burden as an alternative to BVP (Group II) in patients with indications for CRT...

The disproportionate rise of pulmonary artery pressure compared to systemic blood pressure during exercise can lead to detrimental right ventricular remodelling in endurance athletes. Horses may act as an extreme model of these athletic cardiovascular adaptations, as they show a three fold increase in pulmonary pressures during exercise. Right ventricular function was examined in ten healthy horses using post-exercise and pharmacological stress echocardiography in a randomised cross-over design. Exercise testing was performed on a treadmill while pharmacological testing was performed using an atropine-dobutamine infusion...

BACKGROUND: In addition to right ventricular dysfunction (RVD) and myocardial injury, impaired renal function is connected with poorer prognosis in pulmonary embolism (PE). We aimed to investigate renal function as a cofactor for risk stratification in PE. METHODS: Data from 182 patients with PE, treated between May2006 and June2011, were analysed retrospectively. PE patients with elevated creatinine were compared with those with normal values. Logistic regression models were calculated to investigate associations between creatinine and myocardial necrosis, RVD and in-hospital death...

Duchenne muscular dystrophy (DMD) is an X-linked muscle disorder characterized by progressive, irreversible loss of cardiac and skeletal muscular function. Muscular enlargement in DMD is attributed to oedema, due to the increased cytoplasmic Na+ concentration. The aim in this review is to present the current experience and emphasize the role of cardiovascular magnetic resonance (CMR) in the diagnosis of this condition. DMD patients' survival depends on ventilatory assistance, as respiratory muscle dysfunction was the most common cause of death in the past...

Right ventricular (RV) dysfunction is generally evaluated using analyses of tricuspid annular motion. However, it represents only one aspect of RV performance. Whether measuring pulmonary annular motion velocity could serve as a novel way to evaluate global RV and/or RV outflow tract (RVOT) performance in pediatric congenital heart disease (CHD) patients with surgically repaired RVOT was evaluated. In this prospective study, tissue Doppler-derived pulmonary annular motion velocity was measured in children (aged 2-5 years) with RVOT reconstruction (RVOTR group, n = 48) and age-matched healthy children (Control, n = 60)...
