Peripartum cardiomyopathy remains a challenging obstetric and cardiologic emergency. We report 5 interesting cases of peripartum cardiomyopathy with different clinical courses, with 3 patients requiring left ventricular assist device implantation. One patient underwent pump explantation and aortic balloon valvuloplasty postsurgery. Two patients improved with the medical treatment alone without the need of assistance. We will review main important related issues.

OBJECTIVE: Coronary heart disease (CHD) is a frequent medical condition in developed countries and is one of the most serious diseases threatening patients' lives. Perioperative myocardial infarction is the major cause of perioperative cardiac death and cardiac arrest, but is difficult to be precisely identified by observing clinical symptoms or assessing cardiac enzyme levels or by ECG examination. Therefore, assessment of patient prognosis requires reliable predictors. In this regard, we tested the prognostic value of serum troponin I (TnI) concentrations...

Axillary artery access for demanding interventions in newborns is rarely described, in spite of the many clear advantages. This access route in newborns with critical congenital heart disease is a real alternative to the more commonly used femoral or carotid artery routes. In brief, axillary access is an attractive alternative approach in newborns with complex heart diseases. It is advisable to stop an elective procedure if axillary access is not successful. Presently described is the use of axillary artery access for balloon angioplasty in a newborn with critical aortic coarctation...

OBJECTIVE: Transcatheter aortic valve replacement (TAVR) has been accepted as an alternative to surgery in high risk or inoperable patients with severe aortic stenosis (AS). Although transfemoral approach is the most often preferred means of access, in patients with severe ilio-femoral arteriopathy, other vascular access sites may be required. The aim of the present study was to report our experience with trans-subclavian approach for TAVR using different valve systems. METHODS: Among 273 patients undergoing TAVR between June 2011 and May 2016, 10 patients (mean age: 68...

This review mainly focuses on the medical and biological role of relatively poor studied enzymes known as sialidases. Structure and function of sialic acid, particularly as a component of gangliosides and plasma lipoproteins is described. Among the whole variety of sialidases, trans-sialidase is of special interest, since it is capable of removing sialic acid from the low density lipoprotein (LDL) particles and transferring it to different acceptors in plasma. Desialylation of LDL in turn endow them the capacity to accumulate in the smooth muscle cells of human aortic intima, highlighting the important role of desialylation in atherogenesis...

Extracorporeal life support (ECLS) is an important device in the management of children with severe refractory cardiac and or pulmonary failure. Actually, two forms of ECLS are available for neonates and children: extracorporeal membrane oxygenation (ECMO) and use of a ventricular assist device (VAD). Both these techniques have their own advantages and disadvantages. The intra-aortic balloon pump is another ECLS device that has been successfully used in larger children, adolescents, and adults, but has found limited applicability in smaller children...

Background. Increased arterial stiffness is an independent cardiovascular risk factor in diabetes patients and general population. However, the contribution of diabetes to arterial stiffness is often masked by coexistent obesity and hypertension. In this study, we assessed arterial stiffness in nonhypertensive, nonobese type 2 diabetes (T2DM) patients in Ghana. Methods. In case-control design, 166 nonhypertensive, nonobese participants, comprising 96 T2DM patients and 70 nondiabetes controls, were recruited...

AIM: CDKN2A/2B near chromosome 9p21 has been proposed as a potential genetic etiology for both atherosclerosis and arterial calcification. DNA methylation, which can change the expression of CDKN2A/2B, may be an underlying mechanism for this association. This study aimed to evaluate whether CDKN2A/2B methylation is related to aortic arch calcification (AAC) in patients with ischemic stroke. METHODS: DNA methylation levels of CDKN2A/2B was measured using venous blood samples in 322 patients with ischemic stroke...

OBJECTIVES: Bioprosthetic aortic heart valves are increasingly implanted in younger patients. Therefore, a strategy for potential valve failure should be developed before implanting the 'first valve'. The goal of this in vitro study was to provide insight into the effects of the design of a bioprosthesis on a valve-in-valve implanted Sapien XT valve. METHODS: The hydrodynamic performance of a 23-mm Sapien XT valve implanted in Vascutek Aspire, Edwards Perimount, Medtronic Mosaic and St...

There are several issues attributed with abdominal aortic aneurysm endovascular repair. The positioning of bifurcated stent-grafts (SG) may affect SG hemodynamics. The hemodynamics and geometrical parameters of crossing or non-crossing graft limbs have not being totally accessed. Eight patient-specific SG devices and four pre-operative cases were computationally simulated, assessing the hemodynamic and geometrical effects for crossed (n= 4) and non-crossed (n= 4) configurations. SGs eliminated the occurrence of significant recirculations within the sac prior treatment...

Reactive oxygen species (ROS) are key signaling molecules that regulate vascular function and structure in physiological conditions. A misbalance between the production and detoxification of ROS increases oxidative stress that is involved in the vascular remodeling associated with cardiovascular diseases such as hypertension by affecting inflammation, hypertrophy, migration, growth/apoptosis and extracellular matrix protein turnover. The major and more specific source of ROS in the cardiovascular system is the NADPH oxidase (NOX) family of enzymes composed of seven members (NOX1-5, DUOX 1/2)...

Renin inhibitors enhance endothelial nitric oxide synthase (eNOS) bioavailability and have protective effects on endothelial function and atherosclerotic changes. This study was designed to investigate whether aliskiren attenuates the effects of interleukin-6 (IL-6) on eNOS and the eNOS-caveolin-1 interaction in human aortic endothelial cells (HAECs). In this study, we examined the effects of pretreatment with aliskiren on the changes of IL-6-induced expression and activation of eNOS and caveolin-1 in cultured HAECs...

Apelin has been proved to be a critical mediator of vascular function and homeostasis. Here, we investigated roles of Apelin in aortic remodeling and fibrosis in rats with transverse aortic constriction (TAC). Male Sprague-Dawley rats were subjected to TAC and then randomized to daily deliver Apelin-13 (50μg/kg) or angiotensin type 1 receptor (AT1) blocker Irbesartan (50mg/kg) for 4 weeks. Pressure overload resulted in myocardial hypertrophy, systolic dysfunction, aortic remodeling and adventitial fibrosis with reduced levels of Apelin in ascending aortas of rat after TAC compared with sham-operated group...

Transcatheter aortic valve implantation (TAVI) has revolutionized the management of elderly patients with symptomatic severe aortic stenosis in the western world. It is a valuable alternative to surgical aortic valve replacement in patients, who are inoperable or at high surgical risk due to co-morbidities. The prevalence of aortic stenosis increases sharply with age after the sixth decade and is expected to have a significant impact on the geriatric health care system of India, given the rapid increase in life expectancy in recent years...
