Patient: in May 2008, panic and frequent atrial premature chest shaking sensation in August, running 50 meters fainted, take stabilized heart granules. Not good How to treat, take what medicine is good, serious, dangerous, laboratory, examination results: hypertrophic obstructive cardiomyopathy ultrasound: 1, the right ventricular outflow tract is not wide, the root of the aorta is not wide (27mm), the proximal segment of the ascending aorta is not widened (31mm), the aortic valve echoes are normal, the opening can be, the pulmonary artery is not wide, the main trunk diameter (21mm). 2, the left atrium is slightly larger (34mm,) the left ventricle does not The right atrium is not large and the right ventricle is not large. 3, Mitral valve echoes are normal, and opening is possible. The anterior and posterior leaflets are reversed, and the activity curve is bimodal.M-mode: the anterior leaflet of the mitral valve shows SAM sign. 4. The interventricular septum was thickened (the basal segment was thickened by 19 mm, expanding into the left ventricular outflow tract, resulting in narrowing of the left ventricular outflow tract; the middle segment was 15 mm), and the posterior wall of the left ventricle was not thickened (9 mm, with the two moving in the opposite direction, and no stage-by-stage ventricular wall motion abnormalities were seen). The echoes of the atrial septum were continuous, with no obvious interruption. 5, Doppler ultrasound: left ventricular outflow tract systolic blood flow acceleration, peak flow rate: 3.4m / s differential pressure: 45mmHg, mitral valve systolic flow signal can be seen in a small to medium amount of regurgitant blood flow signal, peak flow rate: 2.1m / s, differential pressure: 18mm / Hg mitral valve diastolic blood flow spectral measurements: E peak: 42cm / s, A peak: 97cm / s. 6, the left heart systolic function measurement: EF: 62% (consistent with obstructive hypertrophic cardiomyopathy sonographic changes) Holter showed: 1, abrupt rhythm (average rhythm of 73 beats / min, the slowest rhythm of 51 bpm,, the fastest rhythm of 122 bpm), 2, atrial premature beats (a total of 3 jumps), 3, heart rate variability shows a low. Coronary artery angiography showed roughly normal coronary arteries; left heart catheterization + left ventricular angiography showed systolic phase chambers in a tongue shape, and the systolic pressure of the left heart cavity was significantly higher than that of the left ventricular outflow tract by 80 mm/Hg. Cardiac Surgery Specialist: The flow rate of the left ventricular outflow tract was not fast in ultrasound, but the angiography suggested that the difference in pressure between the left heart cavity and the outflow tract amounted to 80, and the surgical aspect of the left heart cavity and outflow tract may be considered to have a partial septal septostomy, which could be very good to alleviate your symptoms.
