Department of Biomedical Sciences, Humanitas University, Via Rita Levi Montalcini 4, 20072 Pieve Emanuele, Italy.
Pulmonary vein isolation (PVI) represents the cornerstone of paroxysmal (PAF) and persistent atrial fibrillation (PsAF) ablation. Impedance values provide insights on tissue conductive properties. Consecutive patients undergoing PAF and PsAF ablation were prospectively enrolled.

BACKGROUND A single coronary artery is a rare congenital anomaly of the coronary arteries distribution, with an incidence of only 0.03% in the general population undergoing coronary angiography. RCA arising from the distal circumflex artery is an extremely rare variety.

Department of Cardiology, Odense University Hospital, Denmark (N.S.B.M., J.S.D., M.A., A.H., R.C.-S., J.E.M., K.A.Ø., M.-A.C.).
Background: Aortic valve calcification (AVC) has been shown to be a powerful assessment of aortic stenosis (AS) severity and a predictor of adverse outcomes. However, its accuracy in patients with low-flow AS has not yet been proven. The objective of the study was to assess the predictive value of AVC in patients with classical low-flow (CLF, that is, low-flow reduced left ventricular ejection fraction) or paradoxical low-flow (PLF, that is, low-flow preserved left ventricular ejection fraction) AS.

National Manager-Health System Strengthening, United Nations Development Program (UNDP), 55 Lodhi Estate, New Delhi, India.
Background: The purpose of this paper is to compare the efficacy of dual-phase multidetector computed tomography angiography (CTA) with transthoracic echocardiogram (TTE) and cardiac catheterization angiography (CCA) in evaluation of pulmonary arteries and collateral vessels, major aortopulmonary collateral arteries (MAPCAs) in children with cyanotic congenital heart diseases.
Methods: The study was a prospective observational study where 32 pediatric patients (18 males, 14 females and age range 2-116 months) with cyanotic congenital heart diseases (CCHD) were included. All patients underwent TTE, CTA, and CCA.
Successful surgical treatment of left main coronary stenosis with CABG and cardiac resynchronization therapy in a patient after the modified Bentall procedure: A case report.
SAGE Open Med Case Rep

Department of Cardiovascular Surgery, Nagano Red Cross Hospital, Nagano, Japan.
We present a case of an 82-year-old woman who developed sustained heart failure with left ventricular dyssynchrony after the modified Bentall procedure. Persistent circulatory instability and complete atrioventricular block suggested coronary artery stenosis. Multidetector computed tomography revealed stenosis of the grafted portion of the coronary artery.
