Atrial angioleiomyoma with myopericytoma-like features: a case report.

A 66-year-old female patient was referred to our hospital for resection of a right atrial mass. Four months earlier, she had suffered an acute cerebrovascular accident due to occlusion of the sylvian segment of the right middle cerebral artery from atheromatous tight stenosis in the right internal carotid artery. Later, investigations with transthoracic and transesophageal echocardiography revealed a 3.

Baseline subendocardial viability ratio influences left ventricular systolic improvement with cardiac rehabilitation.

Objective: Subendocardial viability ratio (SEVR), defined as diastolic to systolic pressure-time integral ratio, is a useful tool reflecting the balance between coronary perfusion and arterial load. Suboptimal SEVR creating a supply-demand imbalance may limit favorable cardiac response to cardiac rehabilitation (CR). To explore this hypothesis, we designed a study to analyze the relationship between baseline SEVR and response to CR in patients with coronary artery disease (CAD).

Value of Baseline Cardiovascular Mechanics in Predicting Exercise Training Success.

Purpose: Despite being repeatedly shown that exercise training (ET) increases exercise capacity and decreases mortality in many cardiac conditions, not all patients enjoy the benefits of ET programs. We hypothesized that baseline cardiovascular mechanic properties, including cardiac systolic and diastolic functions, arterial mechanics and ventriculoarterial interaction, may have a role in predicting response to ET.

Methods: Full left ventricular pressure-volume loops were constructed and arterial mechanics were evaluated using echocardiographic and tonometric measurements.

Association between baseline cardiovascular mechanics and exercise capacity in patients with coronary artery disease.

Objective: Functional capacity is one of the cardinal determinants of morbidity and mortality in patients with coronary artery disease (CAD). We hypothesized that baseline cardiovascular mechanics, including cardiac systolic and diastolic functions, arterial mechanics, and ventriculoarterial interaction, may play a role in predicting exercise capacity in patients with CAD.

Methods: Fifty consecutive patients with CAD who were referred to cardiac rehabilitation were prospectively included in the study.

Effects of Cardiopulmonary Exercise Rehabilitation on Left Ventricular Mechanical Efficiency and Ventricular-Arterial Coupling in Patients With Systolic Heart Failure.

Background: Success of cardiac rehabilitation (CR) is generally assessed by the objective improvement in peak volume of inhaled oxygen (VO2) measured by cardiopulmonary exercise test (CPX). However, cardiac mechanical efficiency and ventricular-arterial coupling (VAC) are the other important dimensions of the heart failure pathophysiology, which are not included in CPX-derived data. The effect of cardiac rehabilitation on left ventricular (LV) efficiency or VAC in unselected heart failure patients has not been studied thus far.

Effects of exercise on postexercise ventricular-arterial coupling and pulsatile efficiency in patients with systolic dysfunction.

Background: A suboptimal ventricular-arterial (VA) interaction may have a prolonged depressing effect on the failing heart after functional reserves forced to their limits under stress conditions such as exercise. The continuation of excessive load in the postexercise period may be more important than the load during exercise, because the sum of postexercise periods generally exceeds exercise time itself. We sought that exercise-induced changes in postexercise VA coupling and pulsatile efficiency in patients with heart failure (HF).
