The 7-foot heavyweight who fought through a failing heart
In short: Standing at 7 feet tall, Stefan Struve became the tallest fighter in UFC history. But his greatest battle wasn't against opponents in the Octagon; it was against his own physiology. Despite a life-threatening heart condition, Struve spent years navigating the limits of human endurance and medical clearance.
Born in the Netherlands, Struve transitioned from football to martial arts at age 14. By 2008, he had established a professional record of 16–2 before signing a four-fight deal with the UFC. His career was defined by extreme physical contrasts: he possessed a massive 7-foot frame but often faced grueling battles against agile strikers and heavy hitters, earning multiple 'Submission of the Night' and 'Fight of the Night' honors.
In 2013, Struve's career faced a critical turning point when doctors discovered he had a bicuspid aortic valve—meaning his aortic valve had only two leaflets instead of three—alongside an enlarged heart and a leaking aortic valve. This diagnosis forced a hiatus from the sport. While he was eventually cleared by doctors in the Netherlands to return to training in late 2013, his path back to the Octagon was fraught with complications.
The fragility of his condition became public in 2014 when he fainted in a dressing room with an elevated heart rate just before a scheduled fight against Matt Mitrione. Despite these scares, Struve continued to compete, facing high-profile opponents like Alistair Overeem and Alexander Volkov. He eventually retired in February 2021, leaving a legacy as a heavyweight who balanced the pursuit of elite athleticism with a significant medical hurdle.
Struve's journey highlights the intersection of professional sports and cardiology. His ability to secure multiple 'Performance of the Night' bonuses while managing a bicuspid aortic valve underscores the physical toll of MMA. He remains a notable figure in the sport, not just for his record-breaking height, but for his resilience in the face of a chronic heart condition.
