Serum B-type natriuretic peptide levels (BNP) can be used as a predictor of complications in patients undergoing non-cardiac surgery: a prospective observational study.

Objectives: Worldwide, an estimated 10 million adults annually experience significant myocardial injury after non-cardiac surgery. Our aim is to assess whether preoperative and postoperative serum B-type natriuretic peptides levels (BNP) could be used as a predictor of postoperative complications in hypertensive and diabetic patients post non-cardiac surgery.

Design: Prospective observational study.

Factors predicting emergency surgery in severe mitral regurgitation following mitral balloon valvotomy.

Background And Aim Of The Study: Acute mitral regurgitation (MR) may cause adverse hemodynamics following mitral balloon valvotomy (MBV). Some patients become severely hemodynamically unstable and require emergency mitral valve replacement (MVR), while others remain relatively stable with medical management. The study aim was to identify factors that would predict severe acute MR leading to severe hemodynamic compromise requiring emergency MVR.

Comparative efficacy of sildenafil in Eisenmenger's syndrome secondary to atrial septal defect versus ventricular septal defect: a cardiac catheterisation follow-up study.

Objectives: This study evaluates the efficacy and safety of sildenafil in patients with Eisenmenger's syndrome with special emphasis on haemodynamic parameters and its comparative efficacy in atrial septal defect versus ventricular septal defect patients.

Methods: Oral sildenafil was given to 22 patients with Eisenmenger's syndrome - eight with atrial septal defect and 14 with ventricular septal defect - after detailed baseline evaluation including a six-minute walk test, echocardiography, and cardiac catheterisation. Patients were followed up for a period of 6 months for functional class assessment and six-minute walk distance.
