2 meses, todos los pacientes permanecieron asintomaticos (NYHAI) con insuficiencia trivial en dos pacientes, no se demostro gradiente transvalvular en ninguno de los cinco pacientes, con una reduccion significativa de las dimensiones de fin de diastole, concluyendo que esta tecnica conduce a resultados muy satisfactorios a mediano plazo, incluso en presencia de lesiones complejas o dilatacion y deterioro del ventriculo derecho (6, 16).
Mitral inow was assessed from the apical 4-chamber view with pulsed wave doppler by placing sample volume between the tips of the mitral leaets during diastole.
There was no difference between the groups regarding left ventricular end-diastolic dimension, left ventricular end-systolic dimension, interventricular septum thickness in diastole, interventricular septum thickness in systole, left ventricular posterior wall thickness in diastole, left ventricular posterior wall thickness in systole, left atrium dimension, aortic dimension, ejection fraction, and fractional shortening.
31) The compression was found to extend into diastole for up to 30% to 75% of the length of diastole and could compromise myocardial perfusion leading to ischemia.
Theoretically we can infer a relationship, since in the ECG we can identify the systole, starting from the peak of the R wave to peak of the T wave, and the diastole, starting from the peak of the T wave to the peak of the R wave.

Ventricular dyskinesia denotes a segment of the ventricle wall that exhibits a paradoxical, outward movement during systole causing intraventricular "shunting" of blood flow between systole and diastole.
