Reversible Left Ventricular Diastolic Dysfunction Resulting from Frequent Supraventricular Tachycardia.

Left ventricular dysfunction resulting from frequent unifocal ventricular ectopics with resolution following radiofrequency ablation.

A case is presented, in which asymptomatic but persistent right ventricular outflow tract (RVOT) ectopics resulted in left ventricular (LV) dilatation and systolic dysfunction. The patient underwent extensive investigation with no other cause for the cardiomyopathy being found. Successful ablation of the RVOT ectopic focus resulted in normalization of LV size and function. This case suggests th...

Reversible left ventricular dyssynchrony and dysfunction resulting from right ventricular pre-excitation.

We report observations in a 7-year-old girl with right ventricular pre-excitation due to an accessory atrioventricular pathway (AP), and depressed cardiac function. Echocardiographic findings consisted of left ventricular (LV) dilatation with asynchronous ventricular wall motion and diminished LV ejection fraction. Electrophysiological study revealed a para-Hisian AP. She underwent successful A...

echocardiographic assessment of inappropriate left ventricular mass and left ventricular hypertrophy in patients with diastolic dysfunction

background: early diagnosis of left ventricular mass (lvm) inappropriateness and left ventricular hypertrophy   (lvh) can result in preventing diastolic left ventricular dysfunction and its related morbidity and mortality. this study was performed to determine if diastolic dysfunction   is associated with lvh and inappropriate lvm. methods: one hundred   and twenty five uncomplicated hypertensi...

Diastolic Left Ventricular Dysfunction A Clinical Appraisal

Objective: In dilated cardiomyopathy and in athlete’s heart, progressive LV dilatation is accompanied by rightward displacement of thediastolic LV pressure–volume relation. In dilated cardiomyopathy, an increase in diastolic LV stiffness can limit this rightwarddisplacement thereby decreasing LV systolic performance. Because nitric oxide (NO) reduces diastolic LV stiffness, the present ...
