BACKGROUND: Risk of arrhythmic death is considered highest in ischemic heart disease with severe left ventricular ejection fraction (LVEF) reduction. Non-invasive testing should improve decision-making of prophylactic defibrillator (ICD) implantation. METHODS AND RESULTS: We enrolled 120 patients with ischemic heart disease and LVEF <50% and 30 control subjects without ischemic heart disease and normal LVEF. An initial assessment, a second assessment after 3 years, and a final follow-up comprised of: pharmacological baroreflex testing (BRS), short-term spectral (low frequency (LF) to high frequency (HF) ratio) and long-term time domain analysis of heart rate variability (SDNN), exercise Microvolt T-wave alternans (MTWA) and others...

BACKGROUND: Trastuzumab (Herceptin®, Roche) has significantly improved the prognosis of patients with HER2-positive metastatic breast cancer. Some patients remain in remission for many years. However, there are no prognostic markers associated with long-term survival. This study aimed to analyse treatment patterns of HER2-positive metastatic breast cancer at a single institution and explore prognostic factors for long-term survival after HER2-targeted treatment. PATIENTS AND METHODS: This was a retrospective cohort study of all patients with HER2-positive metastatic breast cancer receiving first-line treatment with HER2-targeted therapy between 2004 and 2014 at the University Hospital of Zurich (n = 81)...

Pulmonary hypertension associated with left-sided heart disease (PH-LHD) is the most common type of pulmonary hypertension. In patients with left-sided heart disease, the presence of pulmonary hypertension is typically a marker of more advanced disease, more severe symptoms, and worse prognosis. In contrast to pulmonary arterial hypertension, PH-LHD is characterised by an elevated pulmonary artery wedge pressure (postcapillary pulmonary hypertension) without or with an additional precapillary component (isolated postcapillary versus combined postcapillary and precapillary pulmonary hypertension)...

Relatively few patients with Cornelia de Lange syndrome (CdLS) due to SMC1A mutation have been reported, limiting understanding of the full extent of the phenotype. Compared to children with classic NIPBL-associated CdLS, patients with SMC1A-associated CdLS have a milder physical phenotype with prominent intellectual disability, high rate of cleft palate and absence of limb reductions. We present a patient with SMC1A-associated CdLS who had typical features including developmental delay, seizure disorder, feeding difficulties, hirsutism, and cleft palate...

REVIEW
Abhishek Sharma, Sahil Agrawal, Sunny Goel, Jeffrey S Borer
PURPOSE OF REVIEW: Ischemic mitral regurgitation (MR), which occurs in about 20-30% patients with a prior myocardial infarction, is associated with worsening heart failure and an increase in cardiovascular mortality. It should be treated surgically if certain hemodynamic severity criteria are met and in patients who continue to experience symptoms of heart failure despite optimal medical therapy. However, current guidelines do not suggest which of the available approaches to mitral valve surgery-mitral valve (MV) repair or replacement (MVR) is superior for this indication...

BACKGROUND: Fetal echocardiography (FECG) is a key screening tool for prenatal cardiac abnormalities. Herein, we examined the ultrasonic factors determining prenatal ultrasonic diagnosis of isolated ventricular septal defect (IVSD). METHODS: The diagnostic role of ultrasonic factors was investigated in patients in middle or late pregnancy, diagnosed with IVSD by FECG and confirmed using postnatal echocardiography. RESULTS: One hundred and six patients with IVSD were enrolled; the majority had perimembranous VSD...

BACKGROUND: A key feature of sepsis is systemic inflammatory activation that could be counteracted by steroids. In this experimental model of systemic inflammation, we sought to investigate whether septic neutrophil activation, evaluated by the plasma levels of neutrophil gelatinase-associated protein (NGAL), is modulated by the timing of hydrocortisone treatment. METHODS: Sixteen anesthetized pigs were allocated to one of four equally sized groups. Three of these groups received endotoxin at 2 μg × kg(-1) × h(-1) for 6 h so as to induce endotoxemic shock...

The action mechanism of natakalim, a novel ATP-sensitive potassium channel opener, was studied in ameliorating the congestive heart failure (CHF) after myocardial infarction. A total of 25 healthy Wistar male rats (age, 10 weeks; average weight, 300 g) were selected, and the CHF models after acute myocardial infarction (AMI) were prepared by ligation of left anterior descending branch. They were randomly divided into the sham operation group, the model group and the groups of 1, 3 and 9 mg/kg/day natakalims...

Isolated left subclavian artery is one of the rarer aortic arch anomalies. It has been associated with other congenital heart diseases, typically tetralogy of Fallot, double-outlet right ventricle, and atrial and ventricular septal defects. Its significant clinical implications include a left-to-right shunt from the vertebrobasilar system, which causes pulmonary overcirculation and subclavian steal. We present an unusual case of a premature infant who was diagnosed prenatally with congenital complete atrioventricular block and tricuspid atresia and was found to have an isolated left subclavian artery postnatally...

Atrioventricular septal defects represent a class of congenital cardiac malformations that vary in presentation and management strategy depending upon the severity of the particular lesions present. We present the case of a premature neonate who had a partial atrioventricular septal defect and an accessory mitral (or left atrioventricular) valve leaflet. The latter caused severe left ventricular outflow tract obstruction and severely depressed left ventricular function. We found only one other report of this atrioventricular valve abnormality in association with atrioventricular septal defect...

Left atrial pressure indicates the left ventricular filling pressure in patients who have systolic or diastolic left ventricular dysfunction or valvular heart disease. The use of indirect surrogate methods to determine left atrial pressure has been essential in the modern evaluation and treatment of cardiovascular disease because of the difficulty and inherent risks associated with direct methods (typically the transseptal approach). One method that has been widely used to determine left atrial pressure indirectly is Swan-Ganz catheterization, in which a balloon-flotation technique is applied to measure pulmonary capillary wedge pressure; however, this approach has been associated with several limitations and potential risks...

Chronic tachycardia is a well-known cause of nonischemic cardiomyopathy. We hypothesized that nebivolol, a β-blocker with nitric oxide activity, would be superior to a pure β-blocker in preventing tachycardia-induced cardiomyopathy in a porcine model. Fifteen healthy Yucatan pigs were randomly assigned to receive nebivolol, metoprolol, or placebo once a day. All pigs underwent dual-chamber pacemaker implantation. The medication was started the day after the pacemaker implantation. On day 7 after implantation, each pacemaker was set at atrioventricular pace (rate, 170 beats/min), and the pigs were observed for another 7 weeks...

OBJECTIVE: Xindening oral liquid (Xin) is a widely used traditional Chinese medicine for the treatment of chronic heart failure (CHF). However, the exact mechanisms related to its therapeutic effects against CHF remain unclear. In the present study, we investigate the effects of Xin on cardiac function in CHF rats and the possible mechanisms involved. METHODS: Transverse aortic constriction (TAC) was conducted to induce a CHF rat model in this study. Sixty male Wistar rats were randomly assigned to six groups 28 days after TAC: sham; CHF model; Xin at concentrations of 5 ml/kg, 10 mL/kg, and 20 mL/kg; and QiLi 0...

BACKGROUND: Patients with pulmonary arterial hypertension (PAH) are currently treated with combination therapy of PAH-targeted drugs. Reverse right ventricular (RV) remodeling after lung transplantation (LTx) in patients with end-stage PAH despite combination therapy of PAH-targeted drugs has not been fully elucidated.Methods and Results:A total of 136 patients, including 32 with PAH, underwent LTx from 1998 to 2014. We enrolled 12 consecutive patients with PAH treated with combination therapy of PAH-targeted drugs who underwent LTx and retrospectively analyzed the temporal and serial changes in hemodynamics and echocardiography before LTx and at 3 and 12 months after LTx...

Severe device landing zone calcification (DLZ-CA) predicted paravalvular leak (PVL) and post-dilatation (PD) after transcatheter aortic valve implantation (TAVI). The aim of this study was to determine the influence of DLZ-CA on PVL or PD rates after SAPIEN XT (XT) versus CoreValve (CV).We analyzed patients undergoing TAVI who had severe DLZ-CA. Severe DLZ-CA defined the upper left ventricular outflow tract calcification; the cross-sectional region 2 mm inferior to the annular plane. PVL was evaluated at 30days using transthoracic echocardiography...

An 89-year-old woman appeared to have acute coronary syndrome at the left main trunk (LMT) complicated with severe aortic stenosis, moderate-severe mitral regurgitation, depressed left ventricular (LV) function, and multivessel disease. Because of sustained hypotension even under intra-aortic balloon pumping support during emergency coronary angiograhy, we performed primary percutaneous coronary intervention solely for the LMT lesion using a bare metal stent, leading to recovery from the shock state. On the second hospital day, based on our heart-team consensus, we performed aortic valve replacement and coronary artery bypass grafting surgery, and added edge-to-edge repair (Alfieri stitch) of the mitral valve, resulting in complete revascularization and dramatically improved LV function...

BACKGROUND: Left ventricular ejection fraction (LVEF) and infarct size (ISZ) are key predictors of long-term survival after myocardial infarction (MI). However, little is known about the biochemical pathways driving LV dysfunction after MI. To identify novel biomarkers predicting post-MI LVEF and ISZ, we performed metabolic profiling in the GIPS-III randomized clinical trial (Glycometabolic Intervention as Adjunct to Primary Percutaneous Intervention in ST Elevation Myocardial Infarction)...
