BACKGROUND: Pompe disease is an autosomal recessive disorder caused by deficiency of the lysosomal α-1,4-glucosidase leading to accumulation of glycogen in target tissues with progressive organ failure. While the early infantile-onset form is characterized by early severe hypertrophic cardiomyopathy with cardiac and respiratory failure, clinically relevant cardiomyopathy seems to be uncommon in patients with late-onset Pompe disease, and the prevalence and nature of myocardial abnormalities are still to be clarified...

In pediatric heart transplantation, the size of the donor organ is an important criterion for organ allocation. Oversized donor hearts are often accepted with good results, but some complications in relation to a high donor-recipient ratio have been described. Our patient was transplanted for progressive heart failure in dilated cardiomyopathy. The donor-to-recipient weight ratio was 3 (donor weight 65 kg, recipient weight 22 kg). The intra-operative echocardiography before chest closure showed excellent cardiac function, no tricuspid valve regurgitation, and a normal central venous pressure...

AIMS: Pulmonary hypertension (PH) patients have high mortality due to right ventricular failure. Predictors of poor prognostic outcome are increased right atrial volume (RAV) and elevated mean right atrial pressure (mRAP). Our aim was to determine whether RAV measured with 2D echocardiography (2DE) and 3D echocardiography (3DE) can detect elevated mRAP in patients evaluated for PH. METHODS: Of 85 patients prospectively evaluated for PH, 44 patients (63 ± 15 years, 57% female) had 2DE, 3DE and right heart catheterization within 48 h and were in sinus rhythm...

INTRODUCTION: A fragmented QRS (fQRS) is reported to be associated with a poor prognosis or sudden cardiac death (SCD) in patients with Brugada syndrome or ischemic heart disease. However, no studies have clarified the impact of the presence of an fQRS on SCD or ventricular arrhythmic events in patients receiving cardiac resynchronization therapy (CRT). This study aimed to clarify this point in patients with non-ischemic cardiomyopathy. METHODS AND RESULTS: This study included 137 heart failure patients with non-ischemic cardiomyopathy who received CRT (NYHA functional class: II/III/IV = 25/84/28)...

OBJECTIVE: Few data are available regarding the surgical strategies for an anomalous origin of the left coronary artery (LCA) from the right pulmonary artery (RPA) with an intramural aortic course. We reviewed our experience in a case series of 10 children. METHODS: From 2007 to 2014, 10 patients (7 boys and 3 girls, aged 3 months to 11 years, median 21 months) underwent surgical repair. Before the operation, echocardiography showed the mean left ventricular ejection fraction 45% ± 10% and mean fractional shortening fraction 21% ± 7%...

Right ventricular (RV) pacing has been reported to result in ventricular dyssynchrony, heart failure, and increased mortality. Pacing associated deterioration of left ventricular (LV) systolic function has been termed pacing-induced cardiomyopathy (PICM). While upgrading to biventricular pacing (BiVP) is an effective therapy for PICM, permanent His-bundle pacing (HBP) can be a physiological alternative to BiVP. We present a patient with PICM who responded dramatically to permanent HBP.

OBJECTIVE: To explore the predictive value of heart-type fatty acid binding protein (H-FABP) in the stratification and prognosis of patients with acute pulmonary embolism (APE). METHODS: According to risk stratification, 69 patients with APE admitted into the emergency department within 24 hours after onset were divided into the following 3 groups: high-risk group, moderate-risk group and low-risk group. H-FABP- and cardiac troponin I (cTNI)-positive rates of all groups were analyzed and compared, and the correlation between major adverse events (death, endotracheal intubation and cardiopulmonary resuscitation) and the cardiac markers (heart rate, arterial partial pressure of oxygen, right ventricular dimension, pulmonary arterial pressure, etc...

Chronic pulmonary hypertension (PH) is associated with right ventricular failure and high mortality regardless of the underlying disease. Currently, therapies can improve clinical outcomes in specific subsets of patients, but have little impact on the progression of pulmonary vascular remodeling. Upon new advances in vector development and delivery techniques, gene therapy is a novel strategy in this field with the potential of overcoming the main limitations of approved drug therapies: modulation of novel anti-remodeling targets and selective pulmonary vasculature targeting with minimal systemic effects...

The term tachycardiomyopathy refers to a specific form of tachycardia-related cardiomyopathy caused by supraventricular or ventricular tachyarrhytmias that are both associated with ventricular rates higher than 120 bpm. The arrhythmias which are most frequently associated with these forms of heart disease are atrial fibrillation and atrial flutter, particularly found in the elderly population. The most frequent clinical manifestation is heart failure. In this case we are reporting a clinical case of a patient that came to our attention because of an episode of heart failure associated with atrial fibrillation and atrial flutter...

BACKGROUND: Surgical experience with chronic constrictive pericarditis (CCP) is rarely documented in Africa; the aim of this study is therefore to review our African experience with CCP from 1977 to 2012 in terms of clinical and surgical outcomes and risk factors of early death after pericardiectomy. METHODS: This retrospective study is related to 120 patients with CCP; there were 72 men and 48 women with an average age at 28.8±10.4 years standard deviation (SD) (8-51 years)...

BACKGROUND: Hemorrhagic shock and pneumonectomy causes an acute increase in pulmonary vascular resistance (PVR). The increase in PVR and right ventricular (RV) afterload leads to acute RV failure, thus reducing left ventricular (LV) preload and output. iNO lowers PVR by relaxing pulmonary arterial smooth muscle without remarkable systemic vascular effects. We hypothesized that with hemorrhagic shock and pneumonectomy, iNO can be used to decrease PVR and mitigate right heart failure. METHODS: A hemorrhagic shock and pneumonectomy model was developed using sheep...

BACKGROUND: Right ventricular (RV) dysfunction plays an important role in chronic heart failure (CHF). We evaluated the echocardiographic determinants of one-year all-cause mortality in CHF patients with clinically relevant functional tricuspid regurgitation (TR). METHODS AND RESULTS: A total of 101 consecutive CHF patients (mean age 74±10 years; 53% male) with moderate/severe functional TR were enrolled. Each patient underwent at least two echocardiography examinations in an interval >6 months...

INTRODUCTION: Chronic intermittent renal replacement therapy(RRT) is an alternate method of decongestion for patients presenting with diuretic-resistant, end-stage heart failure(HF) and cardiorenal syndrome. The optimal method of vascular access has not been confirmed. This study compared the 6-month outcomes of patients with end-stage HF after the creation of arteriovenous communications (AVC) versus other means of RRT. METHODS: We treated 40 patients with chronic, intermittent, ambulatory RRT, of whom 15 (37...

Combining echocardiography and cardiopulmonary stress testing allows noninvasive assessment of hemodynamics, and oxygen extraction (A-VO2 difference). We evaluated mechanisms of effort intolerance in patients with heart failure with borderline (40% to 49%) left ventricular ejection fraction (EF) (HF and Borderline Ejection fraction). We included 89 consecutive patients with HF and Borderline Ejection fraction (n = 25; 63.6 ± 14 years, 64% men), control subjects (n = 22), patients with HF with preserved EF (n = 26; EF ≥50%), and patients with HF with reduced EF (n = 16; <40%)...

The presence of systemic left-to-right shunt and increased pulmonary blood flow can result in right heart failure and pulmonary arteriopathy. Correction of left-to-right shunt has been shown to improve cardiac function and physical performance. However, the cardiopulmonary remodeling processes following cessation of left-to-right shunt have yet to be reported. In this experimental study, excessive pulmonary flow was restored through ligation of the aortocaval fistula in rats with flow-induced pulmonary hypertension...

Differentiation of constrictive pericarditis (CP) from restrictive cardiomyopathy (RCM) is a complex and often challenging process. Because CP is a potentially curable cause of heart failure and therapeutic options for RCM are limited, distinction of these 2 conditions is critical. Although different in regard to etiology, prognosis, and treatment, CP and RCM share a common clinical presentation of predominantly right-sided heart failure, in the absence of significant left ventricular systolic dysfunction or valve disease, due to impaired ventricular diastolic filling...

Among patients with sleep apnea the reported prevalence of precapillary pulmonary hypertension (PH) has varied largely, depending on patient selection, disease definition, and associated conditions, in particular chronic pulmonary disease. However, in the absence of comorbidities, PH seems to be rare in patients with sleep apnea. Conversely, sleep-related breathing disorders have been commonly found in patients with PH and they have been associated with an impaired quality of life. Since sleep-related breathing disorders may affect the pulmonary circulation and vice versa, patients with sleep-related breathing disorders should be evaluated for risk factors, symptoms and clinical signs of PH and right ventricular heart failure and patients with PH should be evaluated for sleep apnea...

: Rivaroxaban, a selective inhibitor of active factor X belongs to the group of direct-acting oral anticoagulants (DOAC), more and more often replacing vitamin K antagonists (VKA) in venous thromboembolic disease and nonvalvular atrial fibrillation. Attempts are also being made to use DOAC to treat locally formed intracardiac thrombi, mainly in the left atrium and its appendage, in atrial fibrillation and in heart failure. Rarely diagnosed local right ventricular thrombus (RVT) may be a complication of dilated cardiomyopathy (DCM)...
