A 65-year-old male presented with chest pain that occurred after alcohol drinking at the early morning hours and relieved after taking sublingual nitroglycerin. Coronary angiography revealed a malformed left main coronary artery (LMCA) originating from the right sinus of Valsalva with 10%–20% stenosis and 80% vasospasm. Coronary artery spasm (CAS) in the LMCA is extremely rare but can present with catastrophic features. CAS is more frequently observed in atherosclerotic segments of coronary arteries, and multidetector computed tomography is preferred for assessing the degree of atherosclerosis in cases of LMCA spasm. Anomalous origin of coronary arteries (AOCA) is also rare but can lead to severe symptoms. Although surgical intervention is generally recommended for symptomatic patients, while management of asymptomatic cases remains a topic of ongoing research and debated. In this case, there was concern that the patient’s symptoms might be attributable to AOCA or CAS, medical management was selected over surgical intervention, given the presentation consistent with typical angina due to spasm.

PURPOSE: To study the development of inferior shoulder subluxation after surgery for proximal humerus fractures. To analyze the mechanism development of such subluxation and the association between different types of proximal humerus fractures, quality of reduction achieved the method of operation performed. MATERIALS AND METHODS: A retrospective analysis of 45 proximal humerus fractures that were treated by surgery between March 1997 and July 2002 was done. All patients had a minimum of 12 months of postoperative follow up. Preoperative radiographs were classified by the Neer's classification. Different operative treatment methods, post reduction alignment and the degree of postoperative subluxation if present, were analysed. In order to evaluate effect of loss of negative intraarticular pressure, we compared this series with 15 cases of recurrent shoulder dislocation treated by open Bankart operation. RESULTS: 13 patients out of 45 (29%) developed immediate postoperative inferior shoulder subluxation. 3-part fractures of the proximal humerus showed a higher incidence of the same than the 2-part types. The better reduced fractures had lesser rates of subluxation. Open reduction (39%, 11 patients) results in an increased incidence of inferior subluxation than closed methods of reduction (13%, 2 patients). CONCLUSION: Inferior subluxation of the humeral head after surgery for the proximal humerus fracture can occur and persist till postoperative period of 2 months. Deltoid muscle tone affected by shortening of humeral neck plays an important role. Early active exercise for restoration deltoid tone may be effective in prevention of inferior subluxation.

OBJECTIVES: Cardiopulmonary support has been used to treat the patients with refractory cardiogenic shock since 1950s. In advent of portable system its use has been widened considerably. In this retrospective study, we report our single center experience concerning possible indications, complications and outcomes of percutanous cardiopulmonary support (PCPS). METHODS: From January 2013 to March 2014, we searched the patients who were supported by PCPS system by reviewing the medical records in cardiology department at our Hospital. Infectious organism was limited to what was identified within 2 weeks after weaning of PCPS. RESULTS: A total of 9 patients were supported by PCPS with CAPIOX CX(R) system (Terumo inc., Tokyo, Japan) initially for ST-segment elevation myocardial infarction/non ST-segment elevation myocardial infarction in 4 patients, myocarditis in 3 patients, valvular heart disease in 1 patient, and acute respiratory distress syndrome in 1 patient. The mean duration of PCPS support was 79.1+/-76.6 hours and 5 of them were recovered and discharged alive. All the patients needed transfusions of various forms of blood products. And there was one major stroke and one hyperbilirubinemia in related to PCPS treatment. CONCLUSIONS: PCPS treatment was a valuable means to treat the patients with cardiovascular collapse, but not without costs. Efforts to reduce its associated complications should be made to improve outcomes.

Coronary cameral fistula (CCF) is a rare anomaly, where a communication exists between an epicardial coronary artery and a cardiac chamber. Assessing the hemodynamic significance of the fistula is crucial to make a decision concerning the management process. We present two cases of CCF, draining into the left ventricle, in which the hemodynamic significance was assessed by a fractional flow reserve.

Percutaneous device closure for secundum atrial septal defects (ASDs) has been performed commonly and safely with high success rates. However, it is still challenging to close ASDs that are surrounded with deficient or hypermobile rims and could be compromised with an unexpected migration of device. We report a case of percutaneous Amplazter Septal Occluder (ASO; St. Jude Medical Inc., St. Paul, Minnesota, USA) device closure for an ASD with a thin and floppy interatrial septum, which immediately migrated into the right atrium and was not pulled back into the delivery sheath. To our knowledge, this is the first report on a successful percutaneous retrieval and redeployment of the device in such a situation, preventing any vascular injury or unplanned emergency open heart surgery.

BACKGROUND/AIMS: Chronic thromboembolic pulmonary hypertension (CTEPH) is a life-threatening complication after acute pulmonary embolism (APE) and is associated with substantial morbidity and mortality. This study aimed to investigate the incidence of CTEPH after APE in Korea and to determine echocardiographic predictors of CTEPH. METHODS: Among 381 patients with APE confirmed by chest computed tomography (CT) between January 2007 and July 2013, 246 consecutive patients with available echocardiographic data were enrolled in this study. CTEPH was defined as a persistent right ventricular systolic pressure (RVSP) greater than 35 mmHg on echocardiography during follow-up and persistent pulmonary embolism on the follow-up CT. RESULTS: Fifteen patients (6.1%) had CTEPH. The rate of right ventricular (RV) dilatation (66.7% vs. 28.1%, p = 0.002) and the RVSP (75.5 mmHg vs. 39.0 mmHg, p < 0.001) were significantly higher in the CTEPH group. D-dimers, RV dilatation, RV hypertrophy, RVSP, and intermediate-risk APE were associated with the risk of CTEPH after APE (odds ratio [OR] 0.59, 5.11, 7.82, 1.06, and 4.86, respectively) on univariate analysis. RVSP remained as a significant predictor of CTEPH on multivariate analysis (OR, 1.056; 95% confidence interval, 1.006 to 1.109; p = 0.029). CONCLUSIONS: This study showed that the incidence of CTEPH after APE in Korea was 6.1% and that initial RVSP by echocardiography was a strong prognostic factor for CTEPH.

The best management strategy for angiographically intermediated coronary artery diseases remains controversial. Lesions, when coupled with spasm, can lead to catastrophic results and cardiogenic shock. We report a case of a 62-year-old man who had an intermediate coronary artery disease presenting with cardiogenic shock due to coronary spasm during a preoperative period.

BACKGROUND AND OBJECTIVES: Since echocardiography became a routine diagnostic tool, pericardial effusion has become a common clinical finding. The major causes of hemorrhagic pericardial effusion are malignancy and tuberculosis. However, it was unknown to the use of biochemical analysis of pericardial fluid and serum, for differentiation of malignancy from tuberculosis. To evaluate this, we investigated the biochemical analysis of pericardial fluid and serum in relation to the causes of pericardial tamponade. SUBJECTS AND METHODS: 46 patients who were admitted to Pusan National University Hospital from January 1, 1995, to April 30, 2002, and underwent both a pericardiocentesis and a pericardiostomy for the relif of cardiac tamponade, were included in this study. the pericardial fluid was routinely analyzed for the following: gross appearance, cell count, glucose, total protein(P), lactate dehydrogenase(LDH), cytology, gram stain, cultures for bacteria and mycobacterium, pericardial fluid to serum ratios of total protein and lactate dehydrogenase,(p/s TP, p/s LDH, respectively). RESULTS: f the 46 patients who underwent both pericardiocentesis and pericardiostomy, for the relief of cardiac tamponade, 33 patients(71.7%) had hemorrhagic pericardial effusion. The common causes of hemorrhagic pericardial effusion were malignancy(51.5%) and tuberculosis(33.3%) but, those of nonhemorrhagic pericardial effusion were idiopathic (38.5%). Cell counts were higher in hemorrhagic than nonhemorrhagic group(p=.029). Serum LDH(sLDH) was higher in malignant than tuberculous group(p=.001) but, serum total protein(sTP) was higher in tuberculous group(p=.004). Compared malignant group with tuberculosis group in patients with hemorrhagic pericardial effusion, p/s ratio of LDH and sTP were higher in tuberculous group (p=.029, p=.017), but sLDH was higher in malignant group(p=0.002). CONCLUSION: It is difficult to differentiate tuberculosis from malignancy only on the basis of the biochemical analysis of pericardial fluid in hemorrhagic pericardial effusion. However, the analysis of both pericardial fluid and serum may make it possible to evaluate the cause of pericardial effusion.
