Apicoaortic Conduit (AAC), also known as Aortic Valve Bypass (AVB), is a cardiothoracic surgical procedure that alleviates symptoms caused by blood flow obstruction from the left ventricle of the heart. Left ventricular outflow tract obstruction (LVOTO) is caused by narrowing of the aortic valve (aortic stenosis) and other valve disorders. AAC ...
A Micro-dislodgement is a minimal displacement in the lead that is not visible in a chest X-ray, but has the ability to increase the capture threshold and eventually cause a loss of capture. [5] Lead dislodgement can cause sensing failure, which occurs when proper atrial or ventricular sensing is not achieved by the programming of the pacemaker.
[18] [20] Since its first discovery, there have been many definitions of pacemaker syndrome, and the understanding of the cause of pacemaker syndrome is still under investigation. In a general sense, pacemaker syndrome can be defined as the symptoms associated with right ventricular pacing relieved with the return of A-V and V-V synchrony. [17]
Twiddler's syndrome is a malfunction of a pacemaker due to manipulation of the device and the consequent dislodging of the leads from their intended location. As the leads move, they stop pacing the heart and can cause strange symptoms such as phrenic nerve stimulation resulting in abdominal pulsing or brachial plexus stimulation resulting in rhythmic arm twitching.

Heart disease is consistently the leading U.S. cause of death and accounts for larger medical costs than any other condition. By 2035, the American Heart Association projects that 45% of Americans ...
Each pulse causes the targeted chamber(s) to contract and pump blood, [3] thus regulating the function of the electrical conduction system of the heart. The primary purpose of a pacemaker is to maintain an even heart rate, either because the heart's natural cardiac pacemaker provides an inadequate or irregular heartbeat, or because there is a ...
Sudden heart attack. Stent didn't work. Mentor recommended the cardiologist undergo a rare bypass surgery where the heart still pumps. Uses arteries not veins.
Fox News' John Roberts returned to "America Reports" this week after a recent hospitalization that left him with a pacemaker in his heart. Fox News anchor John Roberts reveals he has a pacemaker ...
