AI Article Synopsis

  • The study explores the management and diagnosis of Wolf-Parkinson White Syndrome (WPW) and asymptomatic pre-excitation in Africa, highlighting a lack of data in the region.
  • Conducted in 20 centers across 17 African countries, the research involved 541 participants and focused on symptomatology, treatment approaches, and the impact of local health dynamics on care.
  • Results indicated that a vast majority were diagnosed with WPW, with significant regional differences in treatment options and effectiveness, showing that Northern and Southern Africa have more advanced practices compared to other areas.

Article Abstract

Background And Aim: Data are scarce regarding Wolf-Parkinson White Syndrome (WPW) syndrome and asymptomatic pre-excitation in Africa. This study tried to understand the current approaches utilized in Africa for the diagnosis and management of both symptomatic and asymptomatic ventricular pre-excitation.

Methods: The current prospective study was conducted in 20 centers located in 17 countries spanning all areas of Africa. Participants included had ventricular pre-excitation patterns. The data collected included symptoms, locations of accessory pathways (AP) and tachyarrhythmia, risk stratification, as well as acute and long-term management. In addition, we assessed the clinical effectiveness of the centers and the impact of socioeconomic and health metrics on these treatment approaches.

Results: Among 541 participants, 93% were diagnosed with WPW syndrome, with orthodromic atrioventricular reciprocating tachycardia (AVRT) being the most prevalent arrhythmia, affecting 55% of the cases. Approximately 30% of patients in Africa, except for the southern region, received intravenous amiodarone as the first-choice drug for orthodromic AVRT while adenosine was the drug of choice in the Southern region. Electrical cardioversion was the first-line treatment for pre-excited atrial fibrillation and antidromic AVRT across all of Africa. Radiofrequency ablation (RF) was the first long-term therapy option for 88% of patients in all African regions, unlike western and central Africa where it was implemented for less than 30% of patients (p < 0.001). The rates of RF success, long-term recurrence, and complications were 93%, 4.1%, and 3.8%, respectively.

Conclusion: There are significant variations between African regions in terms of diagnostic workup, accessory pathway localizations, and volume of invasive treatment. Countries in Northern and Southern Africa are more advanced than other African countries in terms of modern management strategy. Additional government investments are necessary to enhance diagnostic likelihood and curative treatments as well as to reduce the gap between different regions in Africa.

Article Synopsis
  • Fabry disease (FD) is a rare genetic disorder caused by mutations in the GLA gene, resulting in various symptoms, and this study analyzed the characteristics of 52 Mexican FD patients.* -
  • Common symptoms included acroparesthesias, hypohidrosis, heat intolerance, and proteinuria, with more severe renal and neurological issues observed in males; additional findings included cardiac problems and specific skin manifestations.* -
  • The study identified a novel genetic variant associated with an atypical FD phenotype that could resemble Multiple Sclerosis, highlighting the need for renal biopsies for accurate diagnosis when FD is suspected.*

Adjustment disorder encompasses maladaptive emotional, behavioral, and physiologic symptomatology that is related to an identifiable psychosocial stressor. Adjustment disorder manifesting as syncope in a patient with Wolf-Parkinson White (WPW) Syndrome is uncommon and has not previously been documented in medical literature. In this case, we discuss a 24-year-old male with a history of WPW who presented with unexplained, episodic syncope in the setting of acute life stressors.

The inferior vena cava (IVC) is a critical structure for venous return to the heart, and congenital anomalies of the IVC, though rare, can have significant clinical implications during procedures like catheter ablation for arrhythmias. In this case, a 26-year-old male presented with left-sided chest pressure after a routine exercise. Electrocardiography (ECG) revealed a delta wave and shortened PR interval, consistent with Wolf-Parkinson-White (WPW) syndrome, which involves an accessory electrical pathway leading to supraventricular tachycardia.
