Cath Calculator

Cath Calculator is a high-performance clinical and educational tool designed to simplify complex hemodynamic assessments during cardiac catheterization. It serves as a reliable digital companion for cardiologists, fellows, residents, and medical students, transforming raw procedural data into actionable insights in seconds.

Comprehensive Calculation Suite

The app provides a robust set of calculators covering the essential pillars of invasive hemodynamics:

Cardiac Output & Index: Calculate output using the Fick Principle (oxygen consumption) or Thermodilution methods.

Valve Area (Stenosis): Accurately estimate Aortic and Mitral valve areas using the gold-standard Gorlin Equation.

Shunt Fractions (Qp:Qs): Quickly identify and quantify intracardiac shunts for ASD, VSD, and PDA assessments.

Vascular Resistance: Instant calculations for Systemic Vascular Resistance (SVR) and Pulmonary Vascular Resistance (PVR) to guide treatment for heart failure and pulmonary hypertension.

Pressure Gradients: Evaluate mean and peak-to-peak gradients across heart valves.

Why Choose Cath Calculator?

Privacy-First Architecture: We do not collect, store, or share any patient or user data. Your calculations stay on your device.

Offline Functionality: Designed to work in catheterization labs and hospitals with limited connectivity.

Educational Accuracy: Formulas are derived from standard cardiovascular textbooks, making it a perfect study aid for board exams.

User-Centric Interface: A clean, "zero-clutter" design allows for rapid data entry during time-sensitive procedures.

Educational Disclaimer

Cath Calculator is intended for educational and informational purposes only. It is not a medical device and should not be used as the sole basis for patient diagnosis or treatment. Results should always be verified against institutional protocols and clinical judgment.
