An 82-year-old man with a historical past of coronary artery bypass surgical procedure, hypertension and small bowel gastrointestinal stromal tumour underwent cardiac danger analysis previous to surgical resection of his tumour. He was asymptomatic from a cardiovascular perspective, however his exercise degree was lower than 4 metabolic equivalents. Bodily examination was notable for a 2/6 systolic murmur on the apex. ECG confirmed sinus rhythm. A transthoracic echocardiogram was carried out (determine 1 and on-line ).
Transthoracic echocardiography. (A) Mitral valve steady wave Doppler and (B) tricuspid valve steady wave Doppler.
The findings in determine 1 are almost certainly on account of which of the next?
Atrioventricular conduction block.
Acute extreme aortic regurgitation.
Patent ductus arteriosus.
Extreme mitral stenosis.
