| Question | Answer |
| What are supplied by branches of the RCA? | SA and AV nodes are supplied by branches of the RCA. |
| SA and AV nodes are supplied by what? | By branches of the RCA. |
| Infarct may cause what? | Infarct may cause nodal dysfunction (bradycardia or heart block) |
| What supplies the right ventricle? | Right (acute) marginal artery supplies right ventricle |
| What supplies lateral and posterior walls of left ventricle, anterolateral papillary muscle? | Left circumflex coronary artery (LCX) |
| What does Left circumflex coronary artery (LCX) supply? | Supplies lateral and posterior walls of left ventricle, anterolateral papillary muscle |
| What does Right acute marginal artery supply? | Supplies right ventricle |
| What supplies supplies anterior 2/3 of interventricular septum, anterolateral papillary muscle, and anterior surface of left ventricle? | Left anterior descending artery (LAD) |
| What does Left anterior descending artery (LAD) supply? | Anterior 2/3 of interventricular septum, anterolateral papillary muscle, and anterior surface of left ventricle |
| What supplies AV node, posterior 1/3 of interventricular septum, 2/3 posterior walls of ventricles, and posteromedial papillary muscle? | Posterior descending/interventricular artery (PDA)? |
| What does Posterior descending/interventricular artery (PDA) supply? | supplies AV node, posterior 1/3 of interventricular septum, 2/3 posterior walls of ventricles, and posteromedial papillary muscle |
| Which type of circulation? 85% | Right-dominant |
| Which type of circulation? 8% | Left-dominant circulation |
| Which type of circulation? 7% | Codominant circulation |
| Which type of circulation? PDA arises from RCA. | Right-dominant circulation (85%) |
| Which type of circulation? PDA arises from LCX. | Left-dominant circulation (8%) |
| Which type of circulation? PDA arises from both LCX and RCA. | Codominant circulation (7%) |
| In co-dominant circulation (7%), PDA arises from what? | Codominant circulation (7%) = PDA arises from both LCX and RCA. |
| In Left-dominant circulation (8%), PDA arises from what? | Left-dominant circulation (8%) = PDA arises from LCX. |
| In Right-dominant circulation (85%), PDA arises from what? | Right-dominant circulation (85%) = PDA arises from RCA. |
| Coronary artery occlusion most commonly occurs in what? | Coronary artery occlusion most commonly occurs in the LAD. |
| When does coronary blood flow peak? | Coronary blood flow peaks in early diastole. |
| What is the most posterior part of the heart? | The most posterior part of the heart is the left atrium. |
| Enlargement of the left atrium can cause what? Why? | Enlargement can cause dysphagia (due to compression of the esophagus) or hoarseness (due to compression of the left recurrent laryngeal nerve, a branch of the vagus). |
| What are the three layers of pericardium from outer to inner? | Fibrous pericardium Parietal layer of serous pericardium Visceral layer of serous pericardium |
| How many layer of pericardium? | T |
| What is the outer most layer of Pericardium? | Fibrous pericardium |
| What is the inner most layer of Pericardium? | Visceral layer of serous pericardium |
| What is the middle later of Pericardium? | Parietal layer of serous pericardium |
| What lies between the parietal and visceral layers? | Pericardial cavity lies between parietal and visceral layers. |
| Where does the Pericardial cavity lie? | Pericardial cavity lies between parietal and visceral layers. |
| Pericardium is innervated by what? | Pericardium innervated by phrenic nerve. |
| Pericarditis can cause referred pain to what? | Pericarditis can cause referred pain to the shoulder. |
