Differences in left ventricular geometry in hypertensive African-Europeans and Caucasian patients.

Background: There are data showing race-related differences regarding left ventricular (LV) geometry in hypertensive patients. Several authors reported that concentric remodeling is the most common remodeling pattern in hypertensive African-Americans, and this pattern may be related to prognosis. There is little information about the LV remodeling patterns in hypertensive Africans that migrated to Europe, which might have different distributions from those seen in African-Americans.

Value of ejection fraction/velocity ratio in the prognostic stratification of patients with asymptomatic aortic valve stenosis.

Background: The ejection fraction/velocity ratio (EFVR) is a simple function-corrected index of aortic stenosis severity with a good correlation with aortic valve area measured using the Gorlin formula at cardiac catheterization. It is calculated by dividing left ventricular ejection fraction (LVEF) to 4 × (peak jet velocity) .

Objective: Our aim was to evaluate the value of EFVR in predicting adverse events in patients with asymptomatic aortic stenosis.

Heterogeneity of clinical presentation in Tako-Tsubo syndromes: the prevalence of normal segmental wall motion and normal ECG pattern.

Aim: The aim of this study is to report the heterogeneity of clinical presentation in Tako-Tsubo syndrome (TTS), including a significant prevalence of normal ECG and echocardiographic patterns in a series of consecutive patients from a single center.

Methods And Results: From our database we selected a total of 168 cases of TTS. A total of 140 of these (Group A); 14 men (10%), mean age 60.

New classification of geometric ventricular patterns in severe aortic stenosis: Could it be clinically useful?

Background: In severe aortic stenosis, different left ventricle (LV) remodeling patterns as a response to pressure overload have distinct hemodynamic profiles, cardiac function, and outcomes. The most common classification considers LV relative wall thickness and LV mass index to create 4 different groups. A new classification including also end-diastolic volume index has been recently proposed.

Clinical and echocardiographic predictors of long-term outcome of a large cohort of patients with bicuspid aortic valve.

Background And Objectives: Bicuspid aortic valve (BAV) disease is the most common congenital cardiac malformation. The aim of the present article is to determine clinical and echocardiographic prognostic factors and provide a predictive model of outcome of a large cohort of patients with BAV.

Methods: We retrospectively enrolled 337 patients consecutively assessed for echocardiography at our Cardiology Department from 1993 to 2014.

Systemic chemotherapy in combination with pericardial window has better outcomes in malignant pericardial effusions.

Objective: Our aim was to compare systemic chemotherapy (CT) with drainage and with pericardial window in the treatment of neoplastic pericarditis in patients with various malignancies included in the International Neoplastic Pericarditis Treatment study.

Methods: Patients treated with systemic CT alone (Group A), CT plus drainage (Group B), or CT plus pericardial window (Group C) were included. Treatment response was defined as complete response (ie, no more pericardial effusion or masses), partial response (ie, reduced total score, without requiring further treatments), stable disease (ie, unchanged total score), or progressive disease (ie, increased total score).

Incremental value of arterial stiffness over traditional risk factors in predicting subclinical cardiovascular remodeling in patients with moderate chronic renal failure.

Cardiovascular remodeling in chronic kidney disease (CKD) is responsible for the high mortality found in this condition. A total of 89 consecutive outpatients with stage III CKD and 52 patients with stage II CKD with similar degree of traditional atherosclerotic risk factors underwent routine echocardiographic and carotid Doppler examination, evaluating vascular and cardiac remodeling (intima-media thickness [IMT] and left ventricular mass index [LVMi]), and its relation with arterial stiffness, determined in the same examination, using an echo-tracking technique. Also the absolute values of LVMi and IMT were statistically similar between the 2 groups, their determinants were completely different, only in stage III the markers of renal impairment and arterial stiffness being independent predictors of cardiac and vascular modifications.

Neoplastic pericardial disease in lung cancer: impact on outcomes of different treatment strategies. A multicenter study.

Background: Local (intrapericardial) chemotherapy has been reported to be useful for the treatment of neoplastic pericardial disease, but it has never been compared to systemic chemotherapy, a combination of the two and simple pericardial drainage or sclerosis.

Methods: We analyzed the clinical and echocardiographic data of 119 patients, suffering of neoplastic pericarditis due to lung cancer (97 with non-small-cell), comparing the outcomes of four different treatment strategies (extended catheter drainage/sclerosis, systemic chemotherapy, local chemotherapy, and combined - local plus systemic - chemotherapy) at the last available follow-up or at the change of therapy after a treatment failure. The outcomes (based on semiquantitative evaluation of pericardial disease) were classified as complete, partial, no response and progressing disease.

Hydroxymethylglutaryl coenzyme-a reductase inhibitors delay the progression of rheumatic aortic valve stenosis a long-term echocardiographic study.

Objectives: This study sought to assess the effect of hydroxymethylglutaryl coenzyme-A reductase inhibitors (statins) on the progression of rheumatic aortic valve stenosis.

Background: The possible role of statins in slowing the progression of degenerative aortic valve stenosis (AS) is still debated. No information about the role of statin treatment in patients with rheumatic AS is available yet.

Use of the ejection fraction-velocity ratio in the hemodynamic assessment of aortic bioprosthetic valves.

Background: A new echocardiographic severity index of aortic valve stenosis has been recently introduced: the ejection fraction-velocity ratio (EFVR), which is a simple ratio ejection fraction/4Vmax2. This nonflow corrected index demonstrated an excellent accuracy in quantifying the effective orifice area (EOA) in native aortic valves. There is no information about the reliability of EFVR in assessing aortic EOA in patients with bioprostheses.

Left atrium remodeling after acute myocardial infarction (results of the GISSI-3 Echo Substudy).

To evaluate the existence, timing, and determinants of post-infarction left atrial remodeling, we studied a subgroup of 514 patients from the Third Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico Echo Substudy who underwent 4 serial 2-dimensional echocardiograms up to 6 months after acute myocardial infarction. This study is the first to demonstrate, in a large series of patients, the existence of early and late left atrial remodeling after low-risk acute myocardial infarction and the relation of left atrial remodeling to left ventricular remodeling.

Effect of statins on the progression of bioprosthetic aortic valve degeneration.

To date, there is no proved medical therapy able to significantly reduce the degenerative process of biologic prosthetic aortic valves. It has recently been suggested that statins may reduce the progression of native aortic valve stenosis. We examined the effect of statin treatment on bioprosthetic aortic valve degeneration and found a beneficial effect of statins in slowing bioprosthetic degeneration.

Usefulness of exercise test in selected patients coming to the emergency department for acute chest pain.

Background: The management of patients with acute chest pain is a common and difficult challenge for clinicians. In our emergency department (ED) a systematic protocol that involves the use of the exercise test for the management of patients with chest pain of suspected cardiac origin is presently running. The aim of the present study was to evaluate the feasibility of such a test in this setting, in terms of the safety and satisfactory follow-up of these patients discharged home.

Symptomatic aortic stenosis: does systemic hypertension play an additional role?

Hypertension and aortic stenosis represent 2 different models of left ventricular systolic overload. Previous studies have observed different remodeling patterns in these conditions. There is, however, little information about patients with coexisting aortic stenosis and hypertension.

Transesophageal electrical cardioversion of persistent atrial fibrillation: a new approach for an old technology.

Background: Low energy intracardiac cardioversion may be considered the elective, alternative method for the acute restoration of sinus rhythm when direct current cardioversion fails or is contraindicated. Transesophageal cardioversion is a further alternative method for the recovery of sinus rhythm and obviates the potential complications of the low energy intracardiac cardioversion venous approach.

Methods: The present prospective study including 30 patients (21 males, 9 females, mean age 65.

Reliability of new and old Doppler echocardiographic indexes of the severity of aortic stenosis in patients with a low cardiac output.

Background: In addition to the conventional "flow-corrected" parameters (continuity equation and aortic valve resistance), new and simpler Doppler echocardiographic indexes of the severity of aortic stenosis have recently been introduced. These measures can be classified as "function-corrected" indexes (fractional shortening-velocity ratio and ejection fraction-velocity ratio) and "pressure-corrected" indexes (percent stroke work loss). Little information however is available about the diagnostic accuracy of each of these parameters in identifying patients with severe aortic stenosis in low-flow states, in which the diagnosis and clinical decision-making are more difficult and challenging.

Modifications of Oxygen Saturation During Transesophageal Echocardiography.

The present study was designed: (1) to establish the effects of transesophageal echocardiography (TEE) on arterial oxygen saturation (SAO(2)%); (2) to verify the possible clinical consequences of this phenomenon; and (3) to study the possibility of predicting modifications of SAO(2)% by clinical or hemodynamic variables or by specific factors related to the TEE procedure. We prospectively studied 116 unselected patients, aged 61 +/- 12 years, who underwent diagnostic TEE for various clinical indications. Thirty-seven patients had mitral valve disease, 19 aortic valve disease, 14 combined mitroaortic disease, 8 congenital heart disease, and 38 other cardiovascular diseases.
