Influence of the medical treatment schedule in new diagnoses patients with heart failure and reduced ejection fraction.

AIMS: Heart failure (HF) guidelines recommend treating all patients with HF and reduced ejection fraction (HFrEF) with quadruple therapy, although they do not establish how to start it. This study aimed to evaluate the implementation of these recommendations, analyzing the efficacy and safety of the different therapeutic schedules. METHODS AND RESULTS: Prospective, observational, and multicenter registry that evaluated the treatment initiated in patients with newly diagnosed HFrEF and its evolution at 3 months. Clinical and analytical data were collected, as well as adverse reactions and events during follow-up. Five hundred and thirty-three patients were included, selecting four hundred and ninety-seven, aged 65.5 ± 12.9 years (72% male). The most frequent etiologies were ischemic (25.5%) and idiopathic (21.1%), with a left ventricular ejection fraction of 28.7 ± 7.4%. Quadruple therapy was started in 314 (63.2%) patients, triple in 120 (24.1%), and double in 63 (12.7%). Follow-up was 112 days [IQI 91; 154], with 10 (2%) patients dying. At 3 months, 78.5% had quadruple therapy (p < 0.001). There were no differences in achieving maximum doses or reducing or withdrawing drugs (< 6%) depending on the starting scheme. Twenty-seven (5.7%) patients had any emergency room visits or admission for HF, less frequent in those with quadruple therapy (p = 0.02). CONCLUSION: It is possible to achieve quadruple therapy in patients with newly diagnosed HFrEF early. This strategy makes it possible to reduce admissions and visits to the emergency room for HF without associating a more significant reduction or withdrawal of drugs or significant difficulty in achieving the target doses.

Congenital complete absence of pericardium in a young woman with non-specific symptoms.

Congenital absence of the pericardium is a very rare entity that is usually asymptomatic and hence difficult to diagnose. However, cases of sudden death have been reported in patients with partial pericardial defects (even asymptomatic ones), and such patients require surgical treatment. We report the case of a 17-year-old patient with complete pericardial agenesis (diagnosed by chance during a cardiological consultation) and briefly review the radiological findings of this entity.

Monitoring complex secundum atrial septal defects percutaneous closure with real time three-dimensional echocardiography.

BACKGROUND: Atrial septal defect (ASD) is one of the most common congenital heart diseases. Nowadays, percutaneous closure is considered the treatment of choice in most of secundum ASDs. Assessment of the defect and procedure monitoring have been usually performed by angiographic balloon-sizing and/or two-dimensional (2D) transesophageal echocardiography. However, in complex ASDs these techniques might be inaccurate. METHODS: From January 2009 to January 2011 all adult patients with complex ASDs submitted for percutaneous closure were selected. Those defects, where shunts were present through a device previously implanted on the atrial septum or through multiperforated septums, were considered complex ASDs. Two-dimensional transesophageal echocardiography and real time three-dimensional (3D) echocardiography were performed simultaneously during the percutaneous closure procedure. Number of orifices, relationships between the defect, catheter, and device, as well as residual shunt were assessed. RESULTS: Seven patients were included. Five patients had a multiperforated septum and in two cases the defect in the septum was through a previously implanted device. In all cases, 3D echocardiography was superior to 2D echocardiography in relation to the assessment of the relationship between the defect and the catheter or the device. Mechanisms responsible for residual shunts through a device were also better assessed by 3D echocardiography. CONCLUSION: Three-dimensional echocardiography is a safe and useful technique when monitoring percutaneous closure of ASDs, showing relevant advantages over 2D echocardiography.

[Impact of malnutrition on long-term mortality in hospitalized patients with heart failure]. / Influencia de la desnutrición en la mortalidad a largo plazo de pacientes hospitalizados por insuficiencia cardiaca.

INTRODUCTION AND OBJECTIVES: The prevalence of malnutrition among patients with heart failure and the role it might play in prognosis is not currently known. The aim of this study was to analyse the prevalence and risk of malnutrition as well as its possible influence on long-term mortality in patients with heart failure. METHODS: A prospective analysis was conducted on 208 patients discharged consecutively from our centre between January 2007 and March 2008 after being hospitalised with heart failure. Before discharge, a complete nutritional assessment was performed and diagnosis of malnutrition and risk of malnutrition was done with the Mini Nutritional Assessment. Its possible independent association with mortality was assessed by a Cox multivariate analysis. RESULTS: The mean age of the patients was 73 ± 10 years, with 46% women; the most common aetiology of heart failure was ischaemia (41%). In addition, 13% were classified as malnourished, 59.5% at risk of malnutrition and 27.5% were well-nourished. At a median follow-up of 25 months, mortality in the three groups was 76%, 35.9% and 18.9%, respectively (log-rank, P<.001). In the Cox multivariate analysis, the malnutrition state was an independent predictor of mortality (hazard ratio 3.75, 95% confidence interval, 1.75-8.02, P=.001). CONCLUSIONS: Malnutrition and the risk of malnutrition are highly prevalent in patients hospitalised for heart failure. Furthermore, we found that the state of malnutrition as defined by the Mini Nutritional Assessment survey is an independent predictor of mortality in these patients.

Measurement of aortic valve annulus using different cardiac imaging techniques in transcatheter aortic valve implantation: agreement with finally implanted prosthesis size.

AIMS: To compare the measurements of the aortic annulus obtained with various imaging techniques in patients with severe aortic stenosis scheduled for transcatheter aortic valve implantation, and to determine the grade of agreement between the predicted size of the prosthesis for each technique, and the size of the finally implanted valve. METHODS AND RESULTS: The aortic annulus was measured in 40 patients treated by transcatheter aortic valve implantation (CoreValve aortic valve) with transthoracic (TTE) and transesophageal echocardiography (TEE), 64-slice tomography, and angiography. A large valve was implanted when annulus was >23 mm and a small one if it was ≤23 mm. If the size of the prosthesis predicted by several techniques was not the same in one case, we selected the size in which more techniques presented agreement. Forty aortic valves, 26 small and 14 large, were implanted percutaneously. The best correlation was obtained with TTE and TEE (r = 0.93, P < 0.001). The correlation of TTE and TEE with angiography also was good (r = 0.58, P < 0.001 and r = 0.53, P < 0.001, respectively). Correlations between these techniques and computed tomography were poor (P = NS for all comparisons). The best agreement between estimated aortic annulus and implanted valve size was obtained with transtoracic and TEE (κ= 0.88 and 0.76). CONCLUSIONS: The aortic annulus measurements obtained by TTE, TEE, and angiography correlated well, while tomography correlated poorly with other techniques. The imaging techniques that showed the best agreement between estimated aortic annulus size and implanted aortic valve size were TTE and TEE.
