Cardiothoracic Surgeries by Category

Risk Factors for Cardiac Surgeries (N =6,717), 2018 – 2020

Patients with a complex medical background present greater challenges for cardiac surgery. Almost half the patients had diabetes mellitus at time of surgery, and more than two thirds had hypertension and hypercholesterolemia.

In 2020, patients who have had cardiac surgeries had more complex backgrounds than patients at comparable hospitals as evidenced by higher EuroSCORE – Parsonnet average risk scores.

Actual and Predicted Survival Rates for All Types of Open Heart Surgeries

All operations

The survival rate for all open heart surgery was 95.9% in 2020, which is better than the predicted survival rate estimated by the EuroSCORE scoring system.

Isolated Coronary Artery Bypass Grafting (CABG)

The survival rate for CABG surgery was 96.9% in 2020, which is better than the predicted survival rate estimated by the EuroSCORE scoring system.

Mortality Rate for Isolated Mitral Valve Repair, 2018 to 2020 (Total no. of Isolated Mitral Valve Repair patient, N =179)

Mitral Valve Repair is preferred over valve replacement whenever suitable. We report that there was no
death (mortality) for patients undergoing mitral valve repair from 2018 to 2020.

Mortality Rate for Ventricular Septal Defect (VSD) and related procedures, 2018 to 2020

VSD Closure is the commonest surgery for acyanotic congenital heart defects. The death (mortality) rate for simple VSD closure is 0% in 2020.

Mortality Rate for Tetralogy of Fallot (TOF) Correction and related procedures, 2017 to 2020

TOF correction is the most common surgery performed for cyanotic congenital heart defects. The death (mortality) rate for simple TOF correction is 0% in 2019.
