  • Ballooning mitral valve syndrome

    Stenosis means narrowing of an opening, such as a heart valve. Stenosis of the mitral valve limits the forward flow of blood from the left atrium to the left ventricle. This may cause a back-up of blood and fluid in the lungs. Mitral stenosis most commonly develops many years after a person has had rheumatic fever, although many patients diagnosed with mitral stenosis don't recall ever having the illness.

    Causes: Diagnosed with mitral stenosis don’t recall ever having the illness. During rheumatic fever, the valve becomes Mitral stenosis most commonly develops many years after a person has had rheumatic fever, although many patients inflamed. Over time, the leaflets of the inflamed valve stick together and become scarred, rigid and thickened, limiting its ability to open completely.

    Symptoms: Many of the symptoms of mitral stenosis, such as shortness of breath and fatigue, result from a back-up of blood in the lungs. Other symptoms of mitral stenosis may include quick weight gain; weakness; dizziness; swelling in the ankles, feet and/or abdomen (edema); and/or heart palpitations (irregular heartbeat).

    Treatment: A balloon valvotomy is the preferred treatment for mitral valve stenosis. It is a procedure that widens the mitral valve so that blood flows more easily through the heart. A balloon valvotomy is a minimally invasive procedure. A doctor uses a thin flexible tube (catheter) that is inserted through an artery in the groin or arm and threaded into the heart. When the tube reaches the narrowed mitral valve, a balloon device located on the tip of the catheter is quickly inflated. The narrowed or fused mitral valve leaflets are separated and stretched open as the balloon presses against them. This process increases the size of the mitral valve opening and allows more blood to flow from the left atrium into the left ventricle.

    Statistics: Over a 32-month period, 22 consecutive patients with this novel cardiomyopathy were prospectively identified within a community-based practice in the Minneapolis–St. Paul, Minn, area. All patients were women aged 32 to 89 years old (mean 65±13 years); 21 (96%) were ≥50 years of age. The syndrome is characterized by (1) acute substernal chest pain with ST-segment elevation and/or T-wave inversion; (2) absence of significant coronary arterial narrowing by angiography; (3) systolic dysfunction (ejection fraction 29±9%), with abnormal wall motion of the mid and distal LV, ie, “apical ballooning”; and (4) profound psychological stress (eg, death of relatives, domestic abuse, arguments, catastrophic medical diagnoses, devastating financial or gambling losses) immediately preceding and triggering the cardiac events. A significant proportion of patients (37%) had hemodynamic compromise and required vasopressor agents and intra-aortic balloon counterpulsation. Each patient survived with normalized ejection fraction (63±6%; P<0.001) and rapid restoration to previous functional cardiovascular status within 6±3 days. In 95%, MRI identified diffusely distributed segmental wall-motion abnormalities that encompassed LV myocardium in multiple coronary arterial vascular territories.
