Infective endocarditis (IE) after transcatheter aortic valve replacement (TAVR) is a rare complication, but has a high mortality. An 86-year-old female with symptomatic severe aortic stenosis underwent TAVR at our hospital and she was discharged without complication after 10 days. She was readmitted with high fever and acute heart failure 1 month later. Blood culture revealed Staphylococcus, and echocardiography showed vegetation on the septal cusp of the tricuspid valve and perforation at the membranous ventricular septum...

BACKGROUND: Nonspecific ST-T repolarization (NST) abnormalities alter the ST-segment for reasons often unrelated to acute myocardial ischemia, which could contribute to misdiagnosis or inappropriate treatment. We sought to define the prevalence of NST patterns in patients with chest pain and evaluate how such patterns correlate with the eventual etiology of chest pain and course of hospitalization. METHODS: This was a prospective observational study that included consecutive prehospital chest pain patients from three tertiary care hospitals in the U...

Cardiac sympathetic over-activity is a well-established contributor to the progression of neurogenic hypertension and heart failure, yet the underlying pathophysiology remains unclear. Recent studies have highlighted the importance of acutely regulated cyclic nucleotides and their effectors in the control of intracellular calcium and exocytosis. Emerging evidence now suggests that a significant component of sympathetic over-activity and enhanced transmission may arise from impaired cyclic nucleotide signalling, resulting from compromised phosphodiesterase activity, as well as alterations in receptor-coupled G-protein activation...

A 37-year-old man presented with heart failure caused by severe aortic regurgitation (AR). He had a history of being involved in a traffic accident 3 months earlier. Imaging tests at admission detected no abnormalities in the aortic valve or aortic wall; however, the left coronary cusp prolapsed slightly on transthoracic echocardiography. He underwent aortic valve replacement because of uncontrolled heart failure and severe AR. Intraoperatively, the intima of the aortic wall just above the commissure of the left and right coronary cusps was torn to the short axial direction...

Chagas Disease (CD) is a public health problem in Latin America. The acute phase presents nonspecific symptoms and most patients recover from acute parasitemia and undergo a prolonged asymptomatic phase. Several years later, about 30% of infected individuals develop chronic cardiopathy with progressive cardiomegaly, arrhythmia, thromboembolic events, and heart failure. These symptoms suggest a persistent association with the presence of inflammatory infiltrate and tissue, and cellular destruction in the heart muscle...

Heart failure is a burdensome cardiovascular condition associated with high rates of morbidity and mortality. The 3-month period after hospitalization is a vulnerable phase in which patients are at high risk for mortality and rehospitalization. To reduce risk during this period, patients with heart failure and reduced ejection fraction should receive guideline-directed pharmacological therapies-the right drugs at the right doses-before hospital discharge. Optimal pharmacotherapies for these patients include agents that suppress the renin-angiotensin-aldosterone system, suppress the sympathetic nervous system, enhance vasodilation, slow heart rate when needed, and reduce excess volume...

Right heart failure (RHF) is a life-threatening condition. Mechanical right heart support offers an option for critically ill patients. The PERKAT® RV device is designed for percutaneous implantation in acute RHF. It consists of a nitinol chamber covered by foils containing inflow valves. An outlet tube is attached to its distal tip. Using an 18F sheath, it is implanted in the inferior vena cava while the tube bypasses the right heart with its tip in the pulmonary trunk. Then, an IABP balloon is inserted in the pump chamber...

REVIEW

Elevated left atrial (LA) filling pressures are associated with poor prognosis in patients with heart failure (HF). Recent evidences have shown that, in this setting, the presence of restrictive small atrial defect may protect from an extreme increase in LA pressure and prevent consecutive pulmonary congestion and acute decompensation, without the expense of an unfavourable significant left-to-right shunt. Therefore, decompression of LA by creating a unidirectional but restrictive left-to-right interatrial shunt has been emerging as a new therapeutic strategy in patients suffering from both HF with preserved and reduced ejection fraction...

Right ventricular failure (RVF) is the main cause of death in patients with cardiopulmonary disease, such as pulmonary arterial hypertension (PAH), pulmonary embolism, acute respiratory distress syndrome, and right ventricular infarction. The exact cellular and molecular mechanisms underlying RVF remains unclear. Inflammation may play an important role during the development of RVF, as it does in left heart failure. Cardiac inflammation has been shown in RVF patients and animal models, which played a role in the impairment of the right ventricular contraction and in the maladaptive remodeling...

BACKGROUND: Targeted treatment for decompensated right heart failure (RHF) with or without left heart failure is lacking. Vasopressin antagonists (vaptans) may offer an option by increasing urine output and fluid mobilization when used in acute decompensated RHF without impacting blood pressure or renal function, both common complications of loop diuretics. METHODS AND RESULTS: We searched electronic medical records from 2 institutions over 4 years for patients with RHF treated with vaptans...

KEY POINTS: The vascular endothelial growth factor (VEGF) responses to acute submaximal exercise and training effects in patients with heart failure with reduced ejection fraction (HFrEF) were investigated. Six patients and six healthy matched controls performed knee-extensor exercise (KE) at 50% of maximum work rate before and after (only patients) KE training. Muscle biopsies were taken to assess skeletal muscle structure and the angiogenic response. Before training, during this submaximal KE exercise, patients with HFrEF exhibited higher leg vascular resistance and greater noradrenaline spillover...
