To those who suggest that Cardiology does not require problem solving skills, I suggest actually observing what a cardiologist does in practice. Doing a rotation in the CCU or working in an outpatient clinic does not give a complete, or even partially complete picture of the myriad of skills required to be a competent cardiologist.
A few examples of the problem solving skills required are:
1) Actually knowing how to read an ECG correctly. The absolute lack of this skill in the general medical community is astounding, as should be expected, given the lack of training.
2) Learning to perform and interpret transthoracic echocardiography to evaluate complex valve disease, LV and RV function, the significance of LV hypertrophy, identify intracardiac masses, detect intra-cardiac shunts, non-invasively assess cardiac hemodynamics (LA,RA pressure, Pulmonary pressures, valvular gradients, shunt significance, identify coarctation, the list goes on and on...
3) Learning when and how to perform trans-esophageal echocardiography for the evaluation of valvular heart disease and to locate intracardiac shunts. Identify thrombus/tumors, help surgeons identify the particular scallop of the mitral valve that is perforated, identify acute aortic dissection, help the interventionalists decide the appropriateness for percutaneous septal occluder device ASD closure, the list goes on and on...
4) perform exercise and pharmacologic stress echocardiography to identify ischemia, hibernating/stunned myocardium, the significance of borderline positive resting pulmonary hypertension, help differentiate between true aortic stenosis or pseudostenosis in the setting of poor stroke volume and low gradients with a reduced aortic valve area,....the list goes on and on
5) perform and interpret myocardial perfusion imaging for the assessment of ischemia and viability that will ultimately guide management
6) perform and interpret complex electrophysiologic testing to differentiate between a nodal dependent and a bypass dependent supraventricular tachycardia.
7) ablate SVTs, VTs, Atrial fibrillation, and atrial flutter using a combination of fluoroscopy, pace-mapping and complex intracardiac mapping
8) perform and interpret a complex invasive hemodynamic study, using simultaneous right and left heart catheterization to help differentiate restrictive cardiomyopathy and constrictive pericarditis. Use invasive testing to evaluate the significance of pulmonary hypertension; namely helping to differentiate between a primary and secondary cause.
9) Use ECG and or intracardiac electrograms, in a patient with a dual chamber ICD, to differentiate between VT or SVT in the ED.
10) place and follow over time permanent pacemakers and ICDs
11) perform and interpret coronary angiography, bypass graft angiography, LV angiography, Aortography, to decide if complex coronary intervention vs bypass surgery is the best approach
12) Interpret cardiac CTA in the ED in the evaluation of chest pain
13) perform and interpret cardiac MRI to help with congenital cardiac disease, myopathic diseases, myocardial viability, shunt assessment, diagnosis of infiltrative diseases.
The list goes on and on. The field of cardiology is very unique and challenging. I suggest anyone who thinks otherwise, come follow me along in a given day/night.
In my opinion, Cardiology requires the ultimate combination of mental grunt-work, tactile skill, decision making, and equanimity. UNFORTUNATELY, we as the trainees of future physicians in Internal Medicine-and hopefully cardiology, don't always do a good job of demonstrating these points. While medical students get to scrub into surgery, they never get to scrub into a complex valve assessment in the cath lab, or a complex percutaneous intervention. They rarely sit and read echos, read nucs/CTs/MRIs. They are lucky if someone shows them the films. Perhaps this should change.
