“The minimal interaction with the right cardiac chamber resulted in an easy implantation of the pacemaker; the polymer leaflets and the minimal footprint demonstrated an optimal adaptation to the native anatomy and stability through six months’ follow-up.” SOURCES Original Study: 1.Gian Paolo Uss...
Two studies presented at AHA 2024 Scientific Sessions describe the efficacy and safety of left atrial appendage closure after catheter ablation for atrial fibrillation and the 5-year outcomes of the largest randomized left atrial appendage closure trial to date comparing the safety and efficacy of two...
Background We retrospectively investigated whether performing surgical AF ablation at the time of CABG or valve surgery increases the risk of postoperative pacemaker (PPM) requirement. Methods We analyzed the 30 day risk of PPM requirement in consecutive patients undergoing CABG or valve surgery at ...
Cardiac arrhythmia is a broad condition with a range of symptoms, causes and treatments. Learn about it here & book an appointment with our cardiac specialists.
Table 1. Important Tips When Performing Epicardial Puncture, Mapping, and Ablation 1. Knowledge of the patient’s history of open-chest/cardiac surgery, pericarditis, or pericardial instrumentation is essential. 2. Avoidance of systemic anticoagulation until after the epicardial puncture (whenever possibl...

For patients with arrhythmias, this is usually after filling antiarrhythmics and ablation attempts. The second question is whether they're healthy enough for advanced therapies. In other words, how much extracardiac organ involvement do they have from sarcoidosis such as the degree of pulmonary ...
(doctor specializing in electrical disorders of the heart) can determine the exact area causing the arrhythmia. The electrophysiologist, working with your surgeon, may combine ablation (the use of high-energy electrical energy to "disconnect" abnormal electrical pathways within the heart) with left ...
Given that wild-type cells are activated by hyperpolarizing membrane voltages, the inward currents of these channels can contribute to the pacemaker slope (Figure 3, left panel). L-type Ca2+ channels have been described as having a cru- cial role in the excitation-contraction coupling (E–C)...
One sister underwent heart transplant for severe hypertrophic cardiomyopathy at age 15, while another sister had a permanent pacemaker for complete atrio-ventricular block at age 21. No other information is available, likely because the paper mainly focused on the discordant clinical presentation in ...
