Valvular Heart Disease

2013

Valvular heart disease (VHD) refers to a wide spectrum of cardiac disorders that affect a large number of patients. Echocardiography is still considered the pivotal imaging method to evaluate the cardiac valves. However, echocardiography has some intrinsic limitations due to operator dependence and patient habitus. In the last two decades three-dimensional techniques such as magnetic resonance imaging (MRI) and computed tomography (CT) have provided valuable assessment of VHD. MRI overcomes the limitation of the poor acoustic window of echocardiography without ionizing radiation. Nowadays, MRI aims to be considered as the reference standard for imaging cardiac valves because of the improved…

Accumulation of ApoE-containing triglyceride-rich lipoproteins in normolipidemic men with premature coronary artery disease

2000

Accumulation of apoE-enriched triglyceride-rich lipoproteins in patients with coronary artery disease.

2005

Triglycerides (TGs) are vehicled by multiple particles with different abilities to promote atherosclerosis. Among plasma TG-rich lipoproteins (TRLs), subspecies may or may not contain apolipoprotein E (apoE) molecules: in this study, we evaluated the relative contribution of apoE-rich and apoE-poor TRLs to coronary atherosclerosis. We selected a group of males with premature coronary artery disease (CAD) without any of the classical nonlipid risk factors and/or high plasma lipid levels and evaluated the plasma concentration of TRL subspecies in comparison with healthy controls. Patients with CAD and controls had total cholesterol and TG levels within the normal range (despite slightly, even…

Genetic polymorphisms affecting the phenotypic expression in familial hypercholesterolemia

2004

The clinical expression of heterozygous familial hypercholesterolemia (FH) is highly variable even in patients carrying the same LDL receptor (LDL-R) gene mutation. This variability might be due to environmental factors as well as to modifying genes affecting lipoprotein metabolism. We investigated Apo E (2, 3, 4), MTP (-493G/T), Apo B (-516C/T), Apo A-V (-1131T/C), HL (-514C/T and -250G/A), FABP-2 (A54T), LPL (D9N, N291S, S447X) and ABCA1 (R219K) polymorphisms in 221 unrelated FH index cases and 349 FH relatives with defined LDL-R gene mutations. We found a significant and independent effect of the following polymorphisms on: (i) plasma LDL-C (Apo E, MTP and Apo B); (ii) plasma HDL-C (HL, …

Two Italian kindreds carrying the Arg136--Ser mutation of the Apo E gene: development of premature and severe atherosclerosis in the presence of epsi…

2003

Abstract Background and Aims: Type III hyperlipoproteinemia, or dysbetalipoproteinemia, is commonly associated with apolipoprotein E2 homozygosity (Cy Background and Aims: 12, Cy Background and Aims: 58). Apo E2-Christchurch (Arg136→Ser), a rare mutation of the Apo E gene, located in the receptor-binding domain of the protein, has been found to be associated in the vast majority of cases of dysbetalipoproteinemia. Methods and Results: This is the first report of two Italian kindreds carrying the Arg136→Ser mutation. One family is a four-generation kindred from Genoa (Liguria, Italy) with a high rate of mortality due to coronary artery disease: the proband was a 51-year-old woman with previo…

[Cardiovascular health in Asian immigrants to Italy: risk factors, pathogenesis and pharmacological treatment].

2021

In the last decades a significant increase of the migratory phenomenon from South Asian countries to the western world has occurred due to several factors, such as economic crisis, political instabilities, persecutions and wars. It is well established that South Asians (SA) have a higher prevalence of coronary artery disease (CAD) and premature onset of myocardial infarction episodes than other populations. This higher predisposition might be caused by genetic factors, common in both SA residing in their birth country and in those residing abroad, but it may also be due to the new spatial environment in which they live. We have found a higher prevalence of traditional cardiovascular risk fa…

High-frequency rotational ablation following failed percutaneous transluminal coronary angioplasty.

1994

Percutaneous transluminal coronary angioplasty (PTCA) failed in 29 of 1,150 patients (2.5%) after successful passage of the guide wire. The reasons for failure were inability to pass the lesion with a balloon in 28 patients and inability to dilate the lesion in 1 patient. In these patients (15 stenoses and 14 chronic occlusions) rotational ablation was performed. We were able to pass the burr through the lesion in all of them, resulting in a reduction of diameter stenosis from 87 +/- 15 to 51 +/- 18%. Rotational ablation alone was initially successful (stenoses reduction > 20% and residual stenoses < 50%) in 15 of 29 (52%) patients. Additional PTCA was performed in 21 of 29 (72%) patients, …

Successful use of impella CP through femoral access in a patient with bilateral iliac and aortic endoprosthesis in the setting of cardiogenic shock

2019

We report the case of a 67-year-old male, with previous history of severe peripheral vascular disease (abdominal aorta aneurism and bilateral iliac stenosis) requiring the implantation of 3 endoprostheses 7 months ago (Figure 1(A)), and previous myocardial infarction 10 years ago. The left ventricular ejection fraction (LVEF) was preserved at last control (58%). The patient was referred for acute coronary syndrome complicated with pulmonary oedema and cardiogenic shock. Echocardiography showed a severe impairment of LVEF (18%) and the patient was transferred to cathlab for emergency percutaneous coronary intervention (PCI). Coronary angiography via right femoral 7Fr access showed a chronic …

Excimer laser atherectomy in an uncrossable long chronic total occlusion through the subintimal space

2020

We present a successfully chronic total occlusions (CTO) coronary recanalisation with the subadventitial space by excimer laser atherectomy (ELCA) adjunctive therapy. Angiogram revealed non-significant diffuse disease of the left coronary system with a complex long proximal right coronary artery (RCA) CTO (J-CTO score 4) and collaterals (Rentrop Grade 2 and Werner classification CC1) from the septal branches (Figure 1, Panel A). CTO PCI of the RCA was then indicated and planned. Initially, antegrade approach and a retrograde approach technique were attempted without success. Thereafter, a rescue Antegrade Dissection Reentry strategy (ADR) was applied. A Pilot 200 (Abbott) was advanced in a …
