Coronary bypass surgery: to address coronary artery disease, which can lead to an enlarged heart. Left ventricular assist device: (LVAD): to help a weak heart pump, potentially while waiting for a heart transplant or as a long-term treatment for heart failure. Heart transplant: to provide a final option after other treatments fail. [15]
The thickness of the left ventricle as visualized on echocardiography correlates with its actual mass. Left ventricular mass can be further estimated based on geometric assumptions of ventricular shape using the measured wall thickness and internal diameter. [7] Average thickness of the left ventricle, with numbers given as 95% prediction ...
The underlying commonality in these disease states is an increase in pressures that the ventricles experience. For example, in tetralogy of Fallot, the right ventricle is exposed to the high pressures of the left heart due to a defect in the septum; as a result the right ventricle undergoes hypertrophy to compensate for these increased pressures.
Since the pacemaker activates the interventricular septum before the left ventricular free wall, the gradient across the left ventricular outflow tract may decrease. This form of treatment has been shown to provide less relief of symptoms and less of a reduction in the left ventricular outflow tract gradient when compared to surgical myectomy. [62]
This process is particularly apparent in the ventricles, and particularly so in the left ventricle. Noncompaction cardiomyopathy results when there is failure of this process of compaction. Because the consequence of non-compaction is particularly evident in the left ventricle, the condition is also called left ventricular noncompaction. Other ...
Treatment depends on the type of cardiomyopathy and condition of disease, but may include medication (conservative treatment) or iatrogenic/implanted pacemakers for slow heart rates, defibrillators for those prone to fatal heart rhythms, ventricular assist devices (VADs) for severe heart failure, or catheter ablation for recurring dysrhythmias ...
Other findings include dilation of the left ventricle. [29] ECG typically shows left ventricular hypertrophy in patients with severe stenosis, but it may also show signs of left heart strain. [30] Echocardiography is the diagnostic gold standard, which shows left ventricular hypertrophy, leaflet calcification, and abnormal leaflet closure. [30]
The left heart catheterization, on the other hand, gives the pressure in the left ventricle. By simultaneously taking these pressures, it is possible to determine the gradient between the left atrium and left ventricle during ventricular diastole, which is a marker for the severity of mitral stenosis. This method of evaluating mitral stenosis ...
