A 47-year-old man presents for a routine physical examination as part of an insurance medical assessment. He has no complaints and has no family history of cardiac disease or sudden cardiac death. His blood pressure is 120/80 mm Hg, temperature is 36.7°C (98.1°F), and pulse is 75/min and is regular. On physical examination, he appears slim and his cardiac apex beat is of normal character and non-displaced. On auscultation, he has a midsystolic click followed by a late-systolic high-pitched murmur over the cardiac apex. On standing, the click and murmur occur earlier in systole, and the murmur is of increased intensity. While squatting, the click and murmur occur later in systole, and the murmur is softer in intensity. Echocardiography of this patient will most likely show which of the following findings?
