REVIEW
Ajay Kumar Jha, Neeti Makhija
Cor triatriatum is a rare congenital cardiac anomaly defined by an abnormal septation within the atrium (left or right) leading to inflow obstruction to the respective ventricles. It exists either in isolated classical form or may be associated with simple to complex congenital cardiac anomalies. Several anatomical variants exist even in the classical form, and therefore, it may require multimodal diagnostic modalities to characterize and differentiate for better percutaneous interventional or surgical planning...

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...

Right atrial tumor thrombus is rare in patients with visceral malignant tumors and can cause right heart failure or sudden death. We present 2 cases of right atrial tumor thrombus treated under deep hypothermic intermittent circulatory arrest (DHICA). A 45-year-old man with right heart failure was diagnosed with right renal cancer extending to the right atrium. Computed tomography revealed no metastasis. He underwent right nephrectomy and tumor thrombus resection under DHICA. He was discharged on postoperative day 11 in good clinical course...

This study was designed to investigate the expression, activation and activity of matrix metalloproteinase-2 (MMP-2) in the heart of broiler chickens reared in cold conditions and fed with copper-methionine supplement at different levels. The chickens (n=480) were randomly allotted to six treatments and four replicates. Treatments included two rearing temperatures (i.e. normal and cold temperatures) each combined with three levels of supplemental copper-methionine (i.e. 0, 100 and 200mg/kg). On d 38 and 45 of age, four broilers from each treatment were sacrificed and their hearts were stored at -80°C...

BACKGROUND: Pancreatitis is a serious complication after cardiac surgery and can lead to significant morbidities and mortality. The incidence of pancreatitis is even higher in patients undergoing heart transplantation than in those undergoing other cardiac surgeries. Nevertheless, the clinical presentations of pancreatitis are frequently atypical in these patients. CASE PRESENTATION: We report a heart recipient who was complicated with acute right heart failure initially after orthotopic heart transplantation and developed devastating unanticipated hemorrhagic pancreatitis 1 month after the transplantation...

PURPOSE OF REVIEW: The purpose of this review is to identify chronic pulmonary conditions which may often not be recognized preoperatively especially before elective noncardiac surgery and which carry the highest risk of perioperative morbidity and mortality. RECENT FINDINGS: This review discusses some of the most recent studies that highlight the perioperative complications, and their prevention and management strategies. SUMMARY: Pulmonary hypertension is a well recognized risk factor for postoperative complications after cardiac surgery but the literature surrounding noncardiac surgery is sparse...

An idiopathic renal arteriovenous (AV) fistula is a rare malformation of the kidney that may present insidiously with heart failure or hematuria. The treatment may be challenging due to large fistula size that may limit endovascular management. The authors report a case of an 85-year-old Caucasian woman who presented with acute heart failure and was found to have a right renal AV fistula. Since she had no prior history of renal intervention or trauma, a diagnosis of idiopathic renal AV fistula was made. She was managed by endoluminal occlusion using multiple stainless steel coils and Amplatzer vascular plug II device...

Intravenous leiomyomatosis (IVL) is a rare benign tumor of the uterus mesoderm, which can spread via the vein, from the micro-vein to the inferior vena cava, and even to the right atrium. IVL was first described this disease in 1896 and the first presented case of IVL with right atrium extension in the autopsy was described in 1907. On rare occasions, the tumors may extend into the regional and systemic veins, thus reaching the heart. This may subsequently cause intracardiac leiomyomatosis (ICL), which may lead to congestive heart failure and on occasion, sudden fatalities...

Cor triatriatum sinister (CTS) is a rare congenital abnormality. Clinical presentation of patients with CTS mainly depends on the anatomic features of membrane and may vary from mild or moderate symptoms mimicking mitral stenosis to more severe and complicated cardioembolic stroke or a new onset heart failure. We herein have reported on a young male who presented with the signs and symptoms of mitral stenosis and was diagnosed as CTS with gradient on the orifice of the membrane after transthrocacic echocardiography...

Pulmonary arterial hypertension (PAH) is characterized by elevated pulmonary artery pressures and right heart failure. PAH mouse models are instrumental in understanding disease pathophysiology. However, few methods are available to evaluate right cardiac function in small animals. In this study, magnetic resonance imaging (MRI) was used to measure in vivo cardiac dimensions in the Sugen 5416/hypoxia mouse model. Pulmonary hypertension (PH) was induced in C57BL/6 mice by three weeks of exposure to 10% oxygen and VEGF receptor inhibition (20 mg kg(-1) SU5416)...

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...

AIMS: Accumulation of extracellular matrix (ECM) is known to play a crucial role in the pathophysiology of heart failure (HF). However, its prognostic relevance is poorly investigated. METHODS AND RESULTS: A total of 73 HF patients who underwent LV endomyocardial biopsy were enrolled in our study. ECM area was quantified by TissueFAXS and ImageJ software. Patients were followed-up at 6-month intervals. The study endpoint was defined as hospitalization for a cardiac reason and/or cardiac death...

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%)...

A 63-year-old man with sarcoidosis-associated pulmonary hypertension (SAPH) died suddenly of decompensated right heart failure. At autopsy, microscopy showed subpleural and interlobular fibrosis in both upper lobes, with marked broncho-bronchiolectasis, as well as bronchovascular bundle fibrosis and fibrotic organization in alveolar lumens, which are consistent with pulmonary sarcoidosis. Intimal fibrosis and medial hypertrophy were noted in the proximal elastic to distal muscular pulmonary arteries (Heath-Edwards, grades II-III) within intensive fibrotic lesions...
