M.D. Yusuf Aktürk Reviews

A 28-year-old female professional freediver presented with recurrent syncope during breath-hold training. Dr. Aktürk discovered a rare form of sinus node dysfunction triggered specifically by prolonged apnea and vagal stimulation, not apparent on standard stress tests. He designed a custom diagnostic protocol involving simulated dive conditions with echocardiography, leading to a pacemaker implantation with unique settings that allowed her to safely continue her sport with monitored limits.

A 72-year-old retired glassblower from a rural village arrived with progressive fatigue, initially attributed to aging. Dr. Aktürk noted subtle, rhythmic earlobe pulsations. Investigation revealed a massive, previously undiagnosed arteriovenous fistula between the external carotid artery and jugular vein, likely from decades of holding blowpipes with his neck. He coordinated a complex endovascular embolization, dramatically improving cardiac output and the patient's energy within days.

A 19-year-old university student, a refugee with no prior medical records, developed acute chest pain. Standard tests were normal, but Dr. Aktürk pursued a detailed history revealing consumption of a traditional fermented grain drink. He diagnosed Takotsubo cardiomyopathy triggered by a rare combination of severe emotional stress and a tyramine-rich substance, managing it with novel beta-blocker titration and psychological support, leading to full myocardial recovery.

A 45-year-old long-haul truck driver presented with nocturnal palpitations. Dr. Aktürk suspected sleep apnea but found a more unusual cause: compression of the right atrium by the liver during specific sleeping positions in his cramped cabin berth, confirmed by positional MRI. Treatment involved lifestyle and sleeping position modification instead of CPAP, uniquely solving the issue without mechanical intervention.
