Let ’s get down to the nitty-gritty in persistent atrial fibrillation: the continuous critical mass of the atria

I should like to express my hearty congratulations to the authors for this interesting article by Sauet al.1 They conclude that linear ablation, posterior wall isolation, complex fractionated atrial electrogram ablation improves intraprocedural atrial fibrillation (AF) termination. Moreover, left atrial (LA) size directly affects final outcome for AF ablation, by dropping down at a rate of 4% for every 1  mm increase in diameter for freedom from AF.1 Nevertheless, I should like to draw attention to the nitty-gritty.

Authors: Atzema CL, Jackevicius CA, Chong A, Dorian P, Ivers NM, Parkash R, Austin PC Abstract BACKGROUND: Patients with atrial fibrillation frequently seek emergency care. Rates of guideline-concordant oral anticoagulant therapy for stroke prevention are suboptimal in the community. We assessed the association between prescribing of oral anticoagulants in the emergency department (relative to referral to a longitudinal care provider for treatment initiation) and long-term use of oral anticoagulants. METHODS: This retrospective cohort study performed at 15 hospitals in Ontario, Canada, involved patients aged 65...

"Incompatible Housemates": Hypertrophic Obstructive Cardiomyopathy and Takotsubo Syndrome. Intern Med. 2019 Dec 06;: Authors: Sato Y, Matsumoto K, Sakai J, Nakamura T, Tanaka H, Hirata K Abstract This case report concerns an 81-year-old woman with previously well-controlled hypertrophic obstructive cardiomyopathy (HOCM). She was referred to our hospital because of the acute onset of takotsubo syndrome. Echocardiography revealed basal hyperkinesis due to takotsubo syndrome superimposed on septal hypertrophy, which resulted in the reappearance of prominent left ventricular outflow tract obstruc...

LoriganAbstractBackgroundIon channels play crucial roles in cellular biology, physiology, and communication including sensory perception. Voltage-gated potassium (Kv) channels execute their function by sensor activation, pore-coupling, and pore opening leading to K+ conductance.Scope of reviewThis review focuses on a voltage-gated K+ ion channel KCNQ1 (Kv 7.1). Firstly, discussing its positioning in the human ion chanome, and the role of KCNQ1 in the multitude of ...

The author read with great interest the article by Helwani et al. on assessment of hepatic venous Doppler tracings in constrictive pericarditis.1 After a review of constrictive pericarditis and its management, the authors describe the differences between preoperative and intraoperative echocardiographic analysis of the hepatic venous waveforms in various stages of the perioperative period. This case description in particular has very interesting clinical implications given the history of atrial fibrillation, and hence a lack of prominent A wave reversal during expiration in spontaneous, non-positive pressure ventilation (a...
