We report a rare case of right heart failure caused by distal aortic aneurysm. Although aortopulmonary fistula is a common complication of giant aortic arch aneurysm, right heart failure caused by mechanical pressure by aneurysm is very rare. A 79-year-old female patient presented dyspnea. Contrast computed tomography (CT) of the thorax delineated a 78 mm aortic arch aneurysm pressing the main to left pulmonary artery and a 40 mm pericardial effusion at maximum depth at posterior side. Echocardiography showed the acceleration flow from main to left pulmonary artery and moderate pulmonary hypertension...

Severe right ventricular (RV) failure is more likely reversible than similar magnitudes of left ventricular (LV) failure and, because reversal of both adaptive remodeling and impaired contractility require most often only short periods of support, the use of temporary RV assist devices (t-RVADs) can be a life-saving therapy option for many patients. Although increased experience with t-RVADs and progresses made in the development of safer devices with lower risk for complications has improved both recovery rate of RV function and patient survival, the mortality of t-RVAD recipients can still be high but it depends mainly on the primary cause of RV failure (RVF), the severity of end-organ dysfunction, and the timing of RVAD implantation, and much less on adverse events and complications related to RVAD implantation, support, or removal...

OBJECTIVES: Ideal treatment strategies for submassive and massive pulmonary embolism remain unclear. Recent reports of surgical pulmonary embolectomy have demonstrated improved outcomes, but surgical technique and postoperative outcomes continue to be refined. The aim of this study is to describe in-hospital survival and right ventricular function after surgical pulmonary embolectomy for submassive and massive pulmonary embolism with excessive predicted mortality (≥5%). METHODS: All patients undergoing surgical pulmonary embolectomy (2011-2015) were retrospectively reviewed...

Extracorporeal membrane oxygenation (ECMO) has been used increasingly for both respiratory and cardiac failure in adult patients. Indications for ECMO use in cardiac failure include severe refractory cardiogenic shock, refractory ventricular arrhythmia, active cardiopulmonary resuscitation for cardiac arrest, and acute or decompensated right heart failure. Evidence is emerging to guide the use of this therapy for some of these indications, but there remains a need for additional evidence to guide best practices...

BACKGROUND: Although systolic right ventricular (RV) dysfunction has been shown to be a potent predictor for adverse outcomes in patients with heart failure with preserved ejection fraction (HFpEF), RV functional abnormalities in the course of the syndrome are not well characterized. We, therefore, sought to assess load-independent and load-dependent systolic and diastolic characteristics of RV function in stable outpatients with HFpEF. METHODS AND RESULTS: We invasively obtained RV and left ventricular pressure-volume loops in 24 HFpEF patients and 9 patients without heart failure symptoms with a conductance catheter during basal conditions and handgrip exercise...

Recently, implantable cardioverter-defibrillators (ICD) have become capable of monitoring intrathoracic impedance to detect an increased fluid volume and heart failure. Pregnancy is a well-known cause of an increased body fluid volume; however, it is not clear whether the measurement of intrathoracic impedance by ICD is clinically useful for precisely detecting heart failure in pregnant women. We herein report the case of a 39-year-old woman with an ICD that had been implanted after an event of ventricular fibrillation due to severe aortic regurgitation with a bicuspid aortic valve...

BACKGROUND: Transcatheter caval valve implantation is under evaluation as a treatment option for inoperable patients with severe tricuspid regurgitation (TR). The procedure involves the catheter-based implantation of bioprosthetic valves in the inferior vena cava and superior vena cava to treat symptoms associated with TR. This study is the first to evaluate the feasibility, safety, and efficacy of this interventional concept. METHODS AND RESULTS: Twenty-five patients (mean age, 73...

PURPOSE: Multisite cardiac resynchronization therapy (MSCRT) with dual-vein left ventricular (LV) pacing has theoretical advantages over conventional CRT in faster and more physiological LV activation. We aimed to define indications, feasibility, safety, acute, and long-term results of MSCRT. METHODS: All patients implanted with MSCRT during 2008-2014 in a single center were reviewed and analyzed. RESULTS: Thirty-nine patients (90% CRT-defibrillators, 64 ± 9 years, 85% male, 74% ischemic etiology) were included...

Right ventricular (RV) geometry is altered by septal shift after pulmonary artery banding. This may reduce tricuspid regurgitation (TR) and improve ventricular function in patients with corrected transposition of great arteries and systemic right ventricle. However, banding is risky in sick patients with severe RV failure. There are no predictive models in clinical practice to test this septal shift hypothesis before a risky surgery. A transcatheter model to mimic a pulmonary artery band is presented in corrected transposition of great arteries with failing right ventricle and severe TR...

BACKGROUND: Barriers to successful left ventricular lead placement within the coronary venous anatomy may include focal stenoses, thromboses, phrenic nerve stimulation, vessel tortuosity, small vessel caliber, non-excitable tissue and valve presence. A large series describing the utilization of coronary venous angioplasty (CVAP) for relief of these issues is absent in the literature. OBJECTIVE: We report our experience for all patients treated with CVAP in a single-center 13-year experience...

PURPOSE OF REVIEW: We review the trials that have demonstrated potentially harmful effects from right ventricular (RV) apical pacing as well as reviewing the evidence of alternative RV pacing sites and cardiac resynchronization therapy (CRT) for patients who have heart failure and atrioventricular (AV) block. RECENT FINDINGS: The role of CRT in patients with AV block and impaired left ventricular function remains an important consideration. The BLOCK HF trial demonstrated better outcomes with CRT pacing over RV pacing in patients with left ventricular systolic dysfunction (LVSD) and AV block who were expected to have a high RV pacing burden, but failed to demonstrate a mortality benefit...

The definition and classification of cardiomyopathy have evolved considerably in recent years. Cardiomyopathy can be separated into primary (genetic, mixed, or acquired) and secondary categories, which result in varied phenotypes including dilated, hypertrophic, and restrictive patterns. Hypertrophic cardiomyopathy is the most common primary cardiomyopathy and can cause exertional dyspnea, presyncope, atypical chest pain, heart failure, and sudden cardiac death. Dilated cardiomyopathy can be genetic or acquired and typically presents with classic symptoms of heart failure with reduced ejection fraction...

Acute respiratory distress syndrome (ARDS) is the most severe form of acute respiratory failure characterized by diffuse alveolar and endothelial damage. The severe pathophysiological changes in lung parenchyma and pulmonary circulation together with the effects of positive pressure ventilation profoundly affect heart lung interactions in ARDS. The term pulmonary vascular dysfunction (PVD) refers to the specific involvement of the vascular compartment in ARDS and is expressed clinically by an increase in pulmonary arterial (PA) pressure and pulmonary vascular resistance both affecting right ventricular (RV) afterload...

BACKGROUND: The incidence of pleural effusions (PEs) in acute decompensated heart failure (ADHF) is not well established. We aimed to determine their prevalence, clinical characteristics and prognostic implications. METHODS: Retrospective review of 3245 consecutive patients with ADHF from the Spanish RICA Registry. The clinical characteristics of those with or without PEs on chest radiographs were compared and a predictive PE model was generated. RESULTS: Patient's median age was 80 years and 60% had a left ventricular ejection fraction (LVEF) >50%...

BACKGROUND: Presence of adequate current of injury (COI) was recognized as a sign of favorable pacemaker lead outcome. Little is known regarding the value of its dynamic behavior. We sought to test whether persistency of COI could predict active-fixation pacing lead performance. METHODS: COI was monitored up to 10min after right ventricular (RV) pacing electrode fixation. COI persistency was defined as the percentage of COI magnitude relative to its initial measurement...

Long-term right ventricular apical pacing has been associated with detrimental effects, including an increased risk for heart failure, atrial fibrillation, and death. Most of these adverse effects result from ventricular dyssynchrony related to perturbed ventricular depolarization. In addition, biventricular pacing has limited benefits in patients with non-left bundle branch block and severely reduced ejection fraction. Consequently, alternative pacing strategies that mimic natural physiology are desired. Recently, permanent His bundle pacing has emerged as a true physiologic form of ventricular pacing that has been shown to be safe and feasible in clinical practice...

Long-term right ventricular pacing is associated with electrical and mechanical dyssynchrony and ultimately development of pacing-induced cardiomyopathy (PICM) in a subset of patients. Patients with a high degree of pacing burden and reduced left ventricular (LV) function prior to pacemaker implantation are at the greatest risk for developing PICM. Cardiac resynchronization therapy (CRT) has an established role in the treatment of patients with LV systolic heart failure and intraventricular delay and has been used to successfully treat PICM...

Heart failure remains a major public-health problem with an increase in the number of patients worsening from this disease. Despite current medical therapy, the condition still has a poor prognosis. Heart failure is complex but mitochondrial dysfunction seems to be an important target to improve cardiac function directly. Our goal was to analyze the effects of MitoQ (100 µM in drinking water) on the development and progression of heart failure induced by pressure overload after 14 weeks. The main findings are that pressure overload-induced heart failure in rats decreased cardiac function in vivo that was not altered by MitoQ...

Right heart failure (RHF) because of pulmonary hypertension (PH) is a frequently encountered clinical problem with high mortality. The last resort, if pharmacological therapy fails, is mechanical circulatory support. There is a lack of percutaneous systems to support the right ventricle (RV). Venoarterial extracorporeal membrane oxygenation is widely used as a bailout in acute RHF in non-left ventricular assist device patients. Venoarterial extracorporeal membrane oxygenation does not unload the left ventricle and may cause failure of the left ventricle if used for a longer period of time...
