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...

Pulmonary veno-occlusive disease (PVOD) is rare condition which can lead to severe pulmonary hypertension, right ventricular dysfunction, and cardiopulmonary failure. The diagnosis of PVOD can be challenging due to its nonspecific symptoms and its similarity to idiopathic pulmonary arterial hypertension and interstitial lung disease in terms of diagnostic findings. This case describes a 57 year old female patient who presented with a 5-month history of progressive dyspnea on exertion and nonproductive cough...

Acute right ventricular failure (RVF) is an increasingly clinical problem and a life-threatening condition. Right ventricular assist devices (RVADs) represent a reasonable treatment option for patients with refractory RVF. We here present a novel percutaneously implantable device for RV support.The PERKAT device is based on a nitinol stent cage which is covered with valve- carrying foils. A flexible outlet trunk with a pigtail tip is connected to the distal part. The device is driven by an IABP drive unit which inflates/deflates a standard IABP balloon placed within in the stent cage...

OBJECTIVES: The use of short-term mechanical circulatory support (MCS) has increased in the treatment of refractory cardiogenic shock (RCS). Percutaneous short-term MCS technology has emerged rapidly; however, limitations in flow and durability remain. We therefore investigated a minimally invasive surgical approach using an external ventricular assist device (VAD) and extracorporeal membrane oxygenation (ECMO) in patients with RCS. METHODS: Twenty-five patients underwent minimally invasive external VAD insertion with a magnetically levitated centrifugal pump for various causes of cardiogenic shock between April 2010 and May 2016...

BACKGROUND: Pulmonary hypertension (PH) is associated with poor outcomes, yet specific treatments only exist for a small subset of patients. The most common form of PH is that associated with left heart disease (Group 2), for which there is no approved therapy. Nitrite has shown efficacy in preclinical animal models of Group 1 and 2 PH, as well as in patients with left heart failure with preserved ejection fraction (HFpEF). We evaluated the safety and efficacy of a potentially novel inhaled formulation of nitrite in PH-HFpEF patients as compared with Group 1 and 3 PH...

Right Heart Thrombus (RiHT) management is really controversial, and appropriate guidelines are not present for the management. In patients referring with RiHT and Pulmonary Embolism (PE), there are three ways of managing these patients. Out of the three, one is thrombectomy, which is with high risk taking in mind the comorbidities these patients have. The other is using thrombolytic which, in many cases is contraindicated or with high risk. The other less effective way is full anticoagulation. It is really controversial to choose between these ways of management and no clear approach is present...

BACKGROUND: Exercise is beneficial in pulmonary arterial hypertension (PAH), although studies to date indicate little effect on the elevated pulmonary pressures or maladaptive RV hypertrophy associated with the disease. For chronic LV failure, high intensity interval training (HIIT) promotes greater endothelial stimulation and superior benefit than customary continuous exercise training (CExT); however, HIIT has not been tested for PAH. Therefore, here we investigated acute and chronic responses to HIIT vs...

AIMS: Data on the prognostic role of left and right bundle branch blocks (LBBB and RBBB), and nonspecific intraventricular conduction delay (IVCD; QRS ≥ 110 ms, no BBB) in acute heart failure (AHF) are controversial. Our aim was to investigate electrocardiographic predictors of long-term survival in patients with de novo AHF and acutely decompensated chronic heart failure (ADCHF). METHODS AND RESULTS: We analysed the admission electrocardiogram of 982 patients from a multicenter European cohort of AHF with 3...

AIMS: Peripartum cardiomyopathy (PPCM) is a major cause of acute heart failure in the peripartum period and considered potentially life threatening. While many aspects of its clinical profiles have been frequently reported, functional analysis, in particular of the right ventricle, and tissue characterization by cardiovascular magnetic resonance (CMR) imaging have been only sporadically described. The aim of the present study was to analyse pathological alterations and their prognostic relevance found in CMR imaging of patients newly diagnosed with PPCM...

BACKGROUND: The aim of this study was to evaluate the effect of exercise training on cardiac function in heart failure (HF) patients recently suffering from acute decompensation. Radionuclide ambulatory ventricular function monitoring (VEST) was used to detect variations in cardiac hemodynamics during training period. METHODS: This was a monocentric, randomized, controlled trial. We enrolled 72 HF patients [left ventricle ejection fraction (LVEF) <40%] within two weeks after acute cardiogenic pulmonary edema: 40 in the elderly group, 32 in the middle-aged group...

BACKGROUND: Various unfavorable echocardiographic findings other than apical ballooning, such as right ventricular involvement, mitral regurgitation, left ventricular outflow tract obstruction, and left ventricular thrombus, occur in takotsubo cardiomyopathy. Occasionally, these findings are observed simultaneously in a single patient. This study was performed to investigate the prevalence and characteristics of patients with multiple unfavorable echocardiographic findings in takotsubo cardiomyopathy and their associations with adverse outcomes...

OBJECTIVES: Myocardial infarction and chronic heart failure induce specific metabolic changes in the neonatal myocardium that are closely correlated to outcome. The aim of this study was to examine the metabolic responses to noninfarct heart failure and inotropic treatments in the newborn heart, which so far are undetermined. DESIGN: A total of 28 newborn pigs were instrumented with a microdialysis catheter in the right ventricle, and intercellular citric acid cycle intermediates and adenosine metabolite concentrations were determined at 20-minute intervals...

BACKGROUND: Small-scale studies focused mainly on nonischemic cardiomyopathy (NICM) have shown that a subset of left ventricular assist device (LVAD) patients can achieve significant improvement of their native heart function, but the impact of ischemic cardiomyopathy (ICM) has not been specifically investigated. Many patients with acute myocardial infarction are discharged from their index hospitalization without heart failure (HF), only to return much later with overt HF syndrome, mainly caused by chronic remodeling of the noninfarcted region of the myocardium...

BACKGROUND: Transcatheter cryoablation is a well-established technique for the treatment of atrioventricular nodal reentry tachycardia (AVNRT) in children. Nevertheless, atrioventricular nodal slow-pathway conduction may recur after an acutely successful procedure. The aim of this study was to evaluate the long-term outcome of acutely successful AVNRT cryoablations in pediatric patients in case of focal cryolesion and in case of need for High-Density Linear Lesion (HDLL) cryoablation due to focal failure...

BACKGROUND: Pericardial decompression syndrome is defined as paradoxical hemodynamic instability, left ventricular or bi ventricular systolic dysfunction and pulmonary edema after pericardial fluid drainage. Pericardial Decompression Syndrome is an unexpected clinical scenario with an incidence less than 5% in all surgically or percutaneously managed pericardial tamponade patients. The aim of this manuscript was to describe a case with cardiac tamponade in whom acute biventricular heart failure and pulmonary edema developed after surgical creation of a pericardial window, and to discuss this case in light of the literature...

The MitraClip procedure is an emerging endovascular technique for treating mitral regurgitation and an attractive alternative for patients who are at high risk for open heart mitral valve repair or replacement. We present the case of a failed redo MitraClip procedure that led to acute right ventricular failure in a patient with homozygous familial hypercholesterolemia and a preexisting secundum atrial septal defect. We highlight the sequelae of the failed redo MitraClip procedure and the anesthetic challenges associated with the emergent redo sternotomy and cardiopulmonary bypass procedure required to replace the mitral valve and repair the tricuspid valve and atrial septal defect...
