Unguided temporary pacing via jugular/subclavian vein in an emergency department of a high-volume tertiary care hospital of India: its safety, efficacy, and practicability.

Background: Temporary pacing is usually performed by cardiologists under fluoroscopic, echocardiographic, or ECG guidance. However, in the developing world, there are inadequate number of cardiologists, and C-arm, catheterization laboratories, or echocardiography are not available at primary or secondary healthcare facilities. In addition, in emergencies option of fluoroscopy and echocardiography is limited.

Assessment of the Left Atrial Reservoir Function and Left Atrial Volume After Percutaneous Balloon Mitral Valvuloplasty Using Peak Atrial Longitudinal Strain.

Objective To evaluate the impact of successful percutaneous balloon mitral valvuloplasty (BMV) on left atrial (LA) reservoir function and LA volume in patients with severe mitral stenosis (MS) using peak atrial longitudinal strain (PALS). Method This was a prospective, non-randomized observational study conducted at the Laxmipat Singhania (LPS) Institute of Cardiology, Kanpur from August 2018 to February 2020 among patients with severe rheumatic MS undergoing BMV to assess LA reservoir function and its volume after BMV using PALS. Inclusion criteria were symptomatic severe rheumatic MS (NYHA ≥II), normal ventricular systolic function, and suitable valve morphology.
