OBJECTIVES: To describe a new modification, the one-step procedure, that allows interventionists to pre-stent and implant a Melody valve simultaneously. BACKGROUND: Percutaneous pulmonary valve implantation (PPVI) is the standard of care for managing patients with dysfunctional right ventricular outflow tract, and the approach is standardized. METHODS: Patients undergoing PPVI using the one-step procedure were identified in our database. Procedural data and radiation exposure were compared to those in a matched group of patients who underwent PPVI using the conventional two-step procedure...

BACKGROUND: Oxidation of LDL particles entrapped in the extracellular matrix of the arterial wall is a key factor in the development of atherosclerosis. Lipid oxidation products, such as malondialdehyde (MDA), react with surrounding extracellular matrix proteins and cause modifications that are recognized by the immune system. MDA modification of collagen type IV is increased in carotid lesions from symptomatic patients and correlates with autoantibodies against MDA-modified collagen type IV in plasma...

At present, surgical septal myectomy is regarded as the "gold standard" treatment for most patients with obstructive hypertrophic cardiomyopathy (HCM) and drug-refractory symptoms. However, the best results are obtained by those surgeons who have extensive experience with this operation at a small number of referral centers. In the mid-1990s, percutaneous alcohol septal ablation was introduced as an alternative to myectomy to reduce LV outflow gradient and heart failure symptoms in patients with obstructive HCM...

BACKGROUND: Management of hypertrophic obstructive cardiomyopathy (HOCM) has evolved considerably over the last fifty years, and includes medical treatment as well as septal myectomy (SM) to relief symptoms caused by left ventricular outflow tract obstruction (LVOTO). We report the Leipzig Heart Center experience in the surgical management of patients with HOCM. METHODS: We collected data from all patient treated surgically with a myectomy for LVOTO in patients with HOCM between 1997 and 2016...

INTRODUCTION: Regular physical activity (PA) can reduce the risk of developing type 2 diabetes, but adherence to time-orientated (150 min week(-1) or more) PA guidelines is very poor. A practical and time-efficient PA regime that was equally efficacious at controlling risk factors for cardio-metabolic disease is one solution to this problem. Herein, we evaluate a new time-efficient and genuinely practical high-intensity interval training (HIT) protocol in men and women with pre-existing risk factors for type 2 diabetes...

BACKGROUND: When the common femoral artery is not accessible for infrainguinal bypass grafting, the profunda femoris artery (PFA) can be a valuable alternative inflow source for distal arterial revascularization. The purpose of this retrospective study was to evaluate the results of infrageniculate bypass grafting via the PFA as inflow source for critical limb ischemia. METHODS: Between 1994 and 2016, 68 patients, 51 men of a mean age of 74 years, underwent an infrageniculate arterial bypass grafting for critical limb ischemia, using the PFA as inflow site...

Elderly people often suffer adverse health because of inflammation associated with poor metabolism and cardiovascular dysfunction, but these conditions present differently in men and women. We performed experiments in aged male and female mice to understand this sexual dimorphism. We focused on sphingosine 1-phosphate (S1P) signaling, which has both protective and detrimental effects on vascular and metabolic function. We examined vascular function of mesenteric (resistance) arteries from aged male and female wild-type (WT) mice compared to littermate S1P receptor 3 (S1PR3) knockouts (KO)...

OBJECTIVE: Functional endonasal sinus surgery (FESS) is widely practiced and is considered a generally safe procedure. Skull base injuries occur in less than 1% of procedures and are typically associated with cerebrospinal fluid leaks. Rarely, skull base injuries might result in cerebral lesions. Here we present a series of four patients with iatrogenic perforating injuries of the anterior skull base and cerebral lesions after routine FESS. METHODS: Four patients with iatrogenic perforating cerebral lesions after routine FESS performed at other institutions were referred to a tertiary neurosurgery department within a 10-year period...

OBJECTIVE: Recent improvement of best medical treatment for carotid stenosis has sparked a debate on the role of surgery identification of patients who may benefit from carotid endarterectomy (CEA) is crucial to avoid overtreatment. An expected 5-year postoperative survival is one of the main selection criteria. The aim of this study was the development of a score for predicting survival of asymptomatic patients after CEA. METHODS: Our score was derived from a retrospective analysis of 648 consecutive asymptomatic patients from a single hospital...

OBJECTIVE: We evaluated images of patients undergoing a thoracic endovascular aortic repair procedure using two reference points as a means for differentiating stent graft migration from aortic elongation. Conventional standards define migration of a stent graft as an absolute change in the distance from the distal graft ring to a distal landmark ≥10 mm compared with a baseline measurement. Aortic elongation occurs over time in both healthy individuals and patients with aortic disease...

INTRODUCTION: Stent thrombosis (ST) is a rare but catastrophic complication of percutaneous coronary intervention, leading to poor prognosis. Endothelin-1 (ET-1) plays an important role in endothelial dysfunction and thrombogenesis. However, the impact of big ET-1 level on ST in patients with coronary stenting is unknown. We aimed to evaluate big ET-1 level as a potential predictor of ST in patients undergoing percutaneous coronary intervention. MATERIALS AND METHODS: From January 2013 to December 2013, 8106 consecutive patients underwent successful coronary stent implantation and were prospectively enrolled in this study...
