Lone atrial fibrillation”). Other treatments for atrial fibrillation in HCM include the MAZE procedure, in which the electrical connection in the left atria is interrupted at surgery, and is sometimes performed with myectomy. Also, radiofrequency ablation is a novel nonsurgical procedure in which energy is delivered through the tip of a catheter interrupting the abnormal electrical pathways. This treatment is also sometimes referred to as pulmonary vein isolation since the focus for atrial fibrillation is usually in the pulmonary vein Complications of HCM 45 (and not left atrium proper).
Indeed, turbulent blood flow and the degree of obstruction (if present) as well as valve leakage (mitral regurgitation) can be detected and measured with precision. The HCM heart usually shows thickening of the ventricular septum that exceeds that in other parts of the left ventricular wall, whether or not there is obstruction (Figure 12, Figure 17, and Figure 18). The exact pattern of hypertrophy in HCM can be quite diverse. Obstruction occurs when the mitral valve comes forward and contacts the septum during contraction, that is, the systolic anterior motion of the mitral valve known as SAM.
Chest pain Chest pain or pressure (sometimes called angina) is a common symptom. It is usually brought on by exertion and relieved by rest, but may also occur at rest. In HCM, chest discomfort may take different forms – sharp or dull, in the center of the chest or elsewhere or prolonged and unrelated to exertion. The cause of the pain is thought to be insufficient oxygen supply to the heart muscle (ischemia). In HCM, the main coronary arteries are usually free of significant plaque and narrowing from atherosclerosis.
