  • Success in ablation procedures relies on thorough understanding, detailed mapping, careful planning, and the use of advanced imaging technologies.* -
  • Addressing arrhythmogenic sources early and exploring new ablation techniques can enhance success rates and reduce complications, especially in challenging cases.*

Article Abstract

Mapping and ablation of ventricular arrhythmias in patients with nonischemic cardiomyopathies remain a major challenge. The electroanatomic abnormalities are frequently inaccessible to conventional endocardial ablations. Diagnostic diligence with a thorough understanding of the potential mechanisms/substrate, coupled with detailed electroanatomic mapping, is essential. Careful procedural planning, advanced imaging, and unipolar recordings help to formulate ablation strategy, facilitate work flow, and improve outcomes. Inaccessibility of arrhythmogenic substrate and disease progression are important causes of ablation failure. Early intervention may help to improve outcome and minimize complications. Several novel adjunctive ablation techniques are capable of serving as alternative options in refractory cases.

Clinical outcomes of catheter ablation remain suboptimal in patients with atrial fibrillation (AF), particularly in those with persistent AF, despite decades of research, clinical trials, and technological advancements. Recently, pulsed-field ablation (PFA), a promising non-thermal technology, has been introduced to improve procedural outcomes. Its unique feature of myocardial selectivity offers safety advantages by avoiding potential harm to vulnerable adjacent structures during AF ablation.

Premature ventricular contractions (PVCs) are a common finding in patients with surgically repaired congenital heart defects including transposition of the great arteries (D-TGA). While often asymptomatic, PVCs can sometimes lead to palpitations, dyspnea, and hemodynamic compromise, requiring therapeutic intervention. The arterial switch operation is the preferred treatment for D-TGA, but these patients have a 2% incidence of ventricular arrhythmias and 1% incidence of sudden cardiac death post-operatively.

Background: Cryoballoon ablation has been widely performed in patients with paroxysmal atrial fibrillation (AF). In some challenging pulmonary veins (PVs), the procedure requires additional touch-up applications against the residual conduction gaps. It implies that there could exist difficult sites to cover with standard cryoballoon applications (CBAs), resulting in resistant conduction gaps (RCGs).

In response to the challenges faced by the Coati Optimization Algorithm (COA), including imbalance between exploration and exploitation, slow convergence speed, susceptibility to local optima, and low convergence accuracy, this paper introduces an enhanced variant termed the Adaptive Coati Optimization Algorithm (ACOA). ACOA achieves a balanced exploration-exploitation trade-off through refined exploration strategies and developmental methodologies. It integrates chaos mapping to enhance randomness and global search capabilities and incorporates a dynamic antagonistic learning approach employing random protons to mitigate premature convergence, thereby enhancing algorithmic robustness.

Background: Techniques involving dye injection or regional ischemia are commonly used for the precise identification of liver regions during hepatectomy. The visualization of regions with indocyanine green (ICG) has been widely used for liver segmentation. ICG is typically administered only once during each hepatectomy.
