Prof. Hasan Turhan

A 72-year-old retired glassblower from Beykoz presented with progressive fatigue. Despite normal standard tests, Dr. Turhan identified silica particle-induced microvascular coronary dysfunction through advanced coronary flow reserve measurement, a legacy of decades inhaling fine glass dust. Treatment involved targeted vasodilators and a novel pulmonary lavage protocol he co-developed with occupational medicine, resulting in dramatically improved quality of life.

A 19-year-old university student and national chess champion developed paroxysmal atrial fibrillation exclusively during high-stakes tournaments. Dr. Turhan diagnosed 'competition-induced autonomic storm' and implemented a biofeedback-guided vagal training program instead of medication, preserving the patient's mental clarity. The student now uses heart rate variability as a pre-tournament readiness metric.

A 43-year-old transatlantic cargo ship captain with no prior medical access presented during a rare port call. Dr. Turhan diagnosed asymptomatic severe aortic stenosis through a routine screening the captain reluctantly accepted. He coordinated a minimally invasive TAVI procedure within 72 hours before the ship's departure, using a portable anticoagulation monitoring system for the subsequent six-month voyage.

A 35-year-old vegan ultramarathon runner developed unexplained cardiomyopathy. Dr. Turhan identified severe carnitine deficiency due to genetic polymorphisms exacerbated by extreme diet, a condition masked by the patient's athletic physiology. Treatment involved precise amino acid supplementation and dietary modification, with cardiac function normalizing after nine months of tailored metabolic therapy.

A 28-year-old female competitive freediver from Antalya presented with recurrent syncope during breath-hold training. Dr. Turhan discovered an unusual form of neurally mediated hypotension triggered specifically by the Valsalva maneuver at depth. He collaborated with hyperbaric medicine specialists to design a gradual reconditioning protocol using controlled pressure chambers, allowing her to return to competition within six months with modified technique.
