Historical evolution of robot-assisted cardiac surgery: a 25-year journey

Five historical innovations that have shaped modern cardiothoracic surgery

Throughout history, many innovations have contributed to the development of modern cardiothoracic surgery, improving patient outcomes and expanding the range of treatment options available to patients. This article explores five key historical innovations that have shaped modern cardiothoracic surgery: cardiopulmonary bypass, surgical pacemakers, video assisted thoracic surgery, robotic surgery and mechanical circulatory support. We will review the development, impact and significance of each innovation, highlighting their contributions to the field of cardiothoracic surgery and their ongoing relevance in contemporary and perioperative practice.

Minimally-invasive approach via percutaneous femoral cannulation for the resection of intra-cardiac masses: a single center experience in the Middle-East

BACKGROUND

Intra-cardiac masses are rare and challenging lesions with an overall incidence ranging of 0.02-0.2%. Minimally invasive approaches have been recently introduced for surgical resection of these lesions. Here, we evaluated our early experience using minimally invasive techniques in addressing intra-cardiac lesions.

METHODOLOGY

This is a retrospective descriptive study conducted between April 2018 to December 2020. All patients were diagnosed with cardiac tumors and treated via a right mini-thoracotomy with cardiopulmonary bypass through femoral cannulation at King Faisal Specialist Hospital and Research Centre, Jeddah.

RESULTS

Myxoma was the most common pathology representing 46% of cases followed by thrombus (27%), leiomyoma (9%), lipoma (9%) and angiosarcoma (9%). All tumors were resected with negative margins. One patient was converted to open sternotomy. Tumor locations were in the right atrium, left atrium, and left ventricle in 5, 3, and 3 patients, respectively. The median ICU stay was 1.33 days. The median length of hospitalization was 5.7 days. There was no 30-days hospital mortality recorded in this cohort.

CONCLUSION

Our early experience shows that minimally invasive resection can be performed safely and effectively for intra-cardiac masses. The minimally invasive approach using a mini-thoracotomy with percutaneous femoral cannulation can be an effective alternative in resecting intra-cardiac masses that achieves clear margin resection, quick post-operative recovery, and low rates of recurrence for benign lesions.

Artificial Intelligence-Oriented Heart Surgery: A Complex Bioethical Concept

Artificial intelligence (AI) has come to the frontline, paving the way toward a future of operational efficiency. Following the current, cardiac surgery has evolved as well. We live in a world where AI has brought immense progress in almost every aspect of the field, but still, the question remains; will there be a time when robots will replace cardiac surgeons? The currently used operating systems necessitate constant supervision. Upgrading the algorithms from visual augmentation and post-operative prognosis to completely operating software is not something to be taken lightly. However, if we manage to succeed, would you be receptive to a fully autonomous robot as your surgeon? Significant barriers concerning bioethics emerge; the potential for misuse, risk assessment, supervision, referrals, the need to respect and protect patient autonomy and transparency while using the algorithms, and above all the understanding of the dynamics of illness and the human condition. So, can we provide a simple response to such a prime issue? The truth is, we cannot provide an answer for the future where an answer cannot be delivered effortlessly.
