This book is a compilation of various resources, carefully curated with the hope that it will aid our colleagues in their training and preparation for exams such as the MD, FRCSCTS, or Board certifications. It includes a review of essential facts and figures in Cardiothoracic Surgery (CTS), clinical scenarios, and questions that have appeared in previous exams. I have aimed to present the material in a way that will facilitate recall during your exams and enhance your understanding of key concepts. I trust that this book will serve as a valuable tool in your journey toward success in cardiothoracic surgery.
