Is the right ventricular function affected by permanent pacemaker?

Aims: The effect of right ventricular (RV) pacing on left ventricular (LV) function has been extensively evaluated, but the effect on RV function per se has not been evaluated systematically. We aimed to assess the effect of dual chamber pacemaker on RV function.

Methods And Results: All consecutive patients undergoing dual chamber pacemaker from January 2018 to March 2019 for AV block with a structurally normal heart were included.

Long-term clinical outcomes of cardiac sympathetic denervation in patients with refractory ventricular arrhythmias.

Background: Cardiac sympathetic denervation (CSD) is a useful therapeutic option in patients with structural heart disease (SHD) and ventricular tachycardia (VT) who are otherwise refractory to standard antiarrhythmic drug (AAD) therapy or catheter ablation (CA). In this study, we sought to retrospectively analyze the long-term outcomes of CSD in patients with refractory VT and/or VT storm with a majority of the patients being taken up for CSD ahead of CA.

Methods: We included consecutive patients with SHD who underwent CBD from 2010 to 2019 owing to refractory VT.

Asymptomatic chronic traumatic aortic valve perforation with severe aortic regurgitation.

Here, we present a young asymptomatic male patient incidentally diagnosed to have aortic regurgitation (AR). The patient had a history of a blunt trauma to the thorax two years back but did never have any symptoms. Transthoracic echocardiography showed a moderately dilated left ventricle with normal systolic function and severe AR with normal nondilated aortic root and tri-leaflet aortic valve.

Acute hemodynamics of cardiac sympathetic denervation.

Introduction: We aimed to study the immediate hemodynamic effects of thoracoscopic bilateral cardiac sympathetic denervation (CSD) for recurrent ventricular tachycardia (VT) or VT storm.

Method: We studied a group of 18 adults who underwent bilateral thoracoscopic CSD; the blood pressure (BP) and Heart Rate (HR) were continuously monitored during the surgery and up to 6 h post-operatively.

Results: Immediately on removal of the sympathetic ganglia, the patients had a drop in both the systolic (110 mm Hg to 95.
