Accura balloon dilatation catheter for percutaneous balloon pulmonary valvuloplasty among adult patients-its protean use.

Background: Percutaneous balloon pulmonary valvuloplasty (PBPV) is the treatment of choice for hemodynamically significant pulmonary stenosis (PS). Currently, the Tyshak balloon is preferred but requires multiple dilatations because of its instability across the valve leading to a watermelon seeding effect. Accura balloon (Vascular Concept, UK) offers an advantage in its self-positioning configuration, variable diameter, and rapid inflation-deflation sequence which shortens the procedural time and valve injury.

Tiger Stripes in Carditis of Rheumatic Origin.

"Tiger stripes" or "Zebra stripes" are multiple band-like signals noted on Doppler spectral recordings and have been associated with intracardiac oscillating structures. They have been attributed to flail prosthetic valve leaflet, native valve regurgitation without flail leaflet, papillary muscle rupture in acute coronary syndrome, and possibly Lambl's excrescences. To our knowledge, there is only one case report in the English literature that had identified this sign in rheumatic carditis.

Transcatheter closure of secundum atrial septal defect using Cocoon septal occluder: immediate and long-term results.

Background: Atrial septal defect (ASD) is one of the common congenital heart defects. Its management has transformed dramatically in the last 4 decades with the transition from surgical to percutaneous transcatheter closure for most secundum-type ASDs. Various devices are available for transcatheter closure of ASD with Amplatzer atrial septal occluder being most commonly used worldwide.

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.

Balloon Deflection Technique to Facilitate Stent Delivery in Impassable Situations During Percutaneous Coronary Intervention.

Background: Long and multiple lesions especially in the background of tortuous coronary artery often require multiple stents. The entry and passage of another stent through an already deployed stent becomes challenging because of poorly expanded stent struts, calcified tissue, underlying tortuosity, highly angulated takeoff of the vessel, and lack of coaxiality. It can be facilitated by balloon deflection technique (BDT) where balloon at proximal edge of main vessel stent over a buddy wire helps to deflect second stent either distally or into side branch by blocking potential dead.

Epidermal growth factor receptor mutation in adenocarcinoma lung in a North Indian population: Prevalence and relation with different clinical variables.

Introduction: Lung cancer is one of the most common causes of cancer deaths worldwide. Adenocarcinoma is taking over squamous cell lung cancer as the predominant histological subtype. Several cytotoxic drugs are available for the treatment of lung cancer, but side effects limit their use.
