Aortic Stenosis and Transcatheter Aortic Valve Implantation: Current Status and Future Directions in Korea.

Korean Circ J 2019 Apr;49(4):283-297

Department of Internal Medicine, Yonsei University College of Medicine, Seoul, Korea.

Transcatheter aortic valve implantation (TAVI) has been accepted as one of primary options for treatment of symptomatic severe aortic stenosis. Although TAVI has been predominantly used for patients at high risk or with old age who were not considered optimal candidates for surgical aortic valve replacement (SAVR), its indication is now expanding toward low risk profile and younger age. Many clinical trials are now ongoing to test the possibility of TAVI for use in patients even with uncharted indications who are not eligible for SAVR in current guidelines but may benefit from valve replacement.

Chronic Thromboembolic Pulmonary Hypertension: Endovascular Treatment.

Korean Circ J 2019 Mar;49(3):214-222

Departments of Cardiology and Clinical Science, National Hospital Organization Okayama Medical Center, Okayama, Japan.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare cause of pulmonary hypertension; less than 5% of pulmonary hypertension is caused by recurrent pulmonary thromboembolism (PTE). By definition, CTEPH happens within the first two years after symptomatic PTE; however, cases are often diagnosed without a history of acute PTE. Because of the poor functional status and chronicity of this disease, the classic and curative strategy of open pulmonary endarterectomy cannot be applied in some patients with lesions that involve the distal subsegmental pulmonary artery.

Catheter Ablation of Long-standing Persistent Atrial Fibrillation: a Reckless Challenge or a Way to Real Cure?

Authors:
Hui Nam Pak

Korean Circ J 2019 Feb;49(2):134-145

Division of Cardiology, Department of Internal Medicine, Yonsei University Health System, Seoul, Korea.

Long-standing persistent atrial fibrillation (L-PeAF) is a category in which rhythm control is attempted while atrial fibrillation (AF) is maintained for more than 1 year. Because AF is a progressive disease and L-PeAF accompanies significant electrical and structural remodeling of atria, it is difficult to restore and maintain sinus rhythm in patients with L-PeAF. Nonetheless, the rhythm outcome is being increasingly improved by the development of sophisticated mapping devices, highly efficient catheters, and evidence-based ablation strategies, and the rational choice of patient selection criteria.
