Color spectrograph phonocardiography (CSP) is a method for recording heart sounds by using a digital stethoscope. The recorded result can be analyzed by using a soft ware. CSP can identify the opening snap (OS) and measure the S2-OS interval. This study aimed to determine the correlation between adjusted S2-OS to the mitral valve area (MVA) in mitral stenosis (MS) patients. The samples were MS patients admitted to the ICCU and the ward of Prof. Dr. R.D. Kandou Hospital, Manado. Patients with atrial fibrillation were excluded. Every patient underwent echocardiography and CSP to obtain the MVA and S2-OS interval. The adjusted S2-OS interval is the S2-OS interval divided by the number of heart beats (milisecond/beat per minute). Variables were analyzed by using the Pearson correlation test. The results showed that there were 14 MS patients involved in this study. There was a strong correlation between adjusted S2-OS interval and MVA. Estimated MVA was obtained by using the formula MVA = -1.358 + 2.07. Conclusion: The adjusted S2-OS interval was strongly correlated to the MVA of MS Patients and could predict the MVA value. Keywords: color spectrograph phonocardiography, S2-OS interval, mitral valve area, mitral stenosis, echocardiography.   Abstrak: Color spectrograph phonocardiography (CSP) merupakan metode merekam bunyi jantung dengan menggunakan stetoskop digital. Hasil rekaman ini dapat dianalisis dengan piranti lunak. CSP dapat mengidentifikasi opening snap (OS) dan mengukur interval S2 – OS. Penelitian ini bertujuan untuk mendeteksi korelasi antara interval S2-OS yang sudah disesuaikan dengan mitral valve area (MVA) pada pasien mitral stenosis (MS). Sampel penelitian ialah pasien mitral stenosis yang dirawat di ICCU dan bangsal BLU RSUP Prof. Dr. R.D. Kandou Manado. Pasien dengan atrial fibrilasi dieksklusi. Masing-masing pasien menjalani pemeriksaan echocardiography dan CSP untuk memperoleh MVA dan interval S2-OS. Interval S2-OS yang telah disesuaikan adalah interval S2-OS yang dibagi dengan denyut jantung (milidetik/denyut jantung per menit). Variabel-variabel tersebut dianalisis dengan menggunakan analisis korelasi Pearson. Hasil penelitian memperlihatkan  sebanyak 14 pasien mitral stenosis diikutsertakan dalam penelitian. Terdapat korelasi sangat kuat antara interval S2-OS yang telah disesuaikan dengan MVA. Estimasi MVA dapat diperoleh dari persamaan MVA = -1,358 + 2,07.(Interval S2-OS yang telah disesuaikan). Simpulan: Interval S2-OS yang telah disesuaikan memiliki korelasi yang sangat kuat dengan MVA pada pasien-pasien mitral stenosis. Interval S2-OS yang telah disesuaikan dapat memperkirakan nilai MVA. Kata kunci: color spectrograph phonocardiography, interval S2-OS, mitral valve area, mitral stenosis, echocardiography.

Temporary blindness, also known as transient cortical blindness, is an uncommon impediment of contrast agent usage during angiography procedures. The occurrence of blindness after a cardiac catheterization procedure is rare and its pathophysiology remains largely speculative. The most probable mechanism seems to be contrast agent-related disruption of the blood–brain barrier, possibly initiated by several predisposing factors. This case reports a 52-year-old man with transient vision loss that occurred following coronary angiography. Brain magnetic resonance imaging (MRI) showed no acute pathology and his vision spontaneously returned within approximately 15 hours post-procedure without any requirement of specific therapy. Suggesting that transient cortical blindness may have occurred following coronary angiography which subsequently self-resolved.

Abstrak: Fibrilasi atrial merupakan gangguan irama jantung menetap yang paling sering dijumpai di praktek sehari-hari, ditandai oleh adanya aktivasi atrium yang tidak terorganisasi dan kontraksi atrium dan ventrikel yang tidak terkoodinasi. Meskipun banyak laporan mengenai fibrilasi atrial di Indonesia, tetapi hal ini belum pernah dilaporkan di Sulawesi Utara. Penelitian ini bertujuan untuk mendapatkan profil fibrilasi atrial di Manado. Data diambil dari pasien fibrilasi atrial di Bagian Jantung dan Pembuluh Darah, Prof R D Kandou, Manado, sejak September 2012-Februari 2013. Variabel yang diamati ialah jenis kelamin, usia, penyakit penyerta, ekokardiografi, dan terapi. Sebanyak 84 pasien diikutsertakan dalam penelitian ini, terdiri dari 42 laki-laki dan 42 perempuan dengan usia 21-84 tahun dengan rincian 53 pasien berusia ≥60 tahun dan 30 pasien <60 tahun. Pada 59 pasien yang dilakukan ekokardiografi, 39 pasien (66,1%) mempunyai fraksi ejeksi ≥55%; dan 20 pasien (33,9%) <55% (rerata 55,8%). Pembesaran atrium kiri ditemukan pada 33 pasien (55,9%) dan trombus pada 13 pasien (22%). Penyakit penyerta yang ditemukan ialah: hipertensi pada 35 pasien (41,7%); gagal jantung 40 pasien (40,76%); penyakit jantung koroner 20 pasien (23,8%); penyakit jantung katub 21 pasien (25%); penyakit paru 6 pasien (7%); hipertiroid 5 pasien (6%); dan tanpa penyakit penyerta 1 pasien (1,2%). Pada 70 pasien (83,3%) diberikan terapi bisoprolol; 2 pasien (2,4%) digoksin; 3 pasien (3,5%) amiodaron; 7 pasien (8,4%) bisoprolol dan digoksin; dan 2 (2,4%) bisoprolol dan amiodaron. Obat antikoagulan oral diberikan pada 28 pasien (33,03%), dan aspirin pada 40 pasien (47,6%). Stroke ditemukan pada 4 pasien (4,8%); satu orang diantaranya meninggal akibat stroke. Simpulan: Fibrilasi atrial lebih sering ditemukan pada usia lanjut. Gagal jantung dan hipertensi merupakan penyakit penyerta yang tersering, sehingga perlu diwaspadai. Bisoprolol merupakan pilihan terapi yang tersering diberikan, dan angka komplikasi dan kematiannya rendah. Kata kunci: fibrilasi atrial, penyakit penyerta, terapi.   Abstract: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia encountered in clinical practice characterized by disorganized atrial activation and uncoordinated contraction of the atria and ventricle. Although there are many reports regarding the profile of atrial fibrillation (AF) in Indonesia, none have been published in North Sulawesi. This study aimed to provide epidemiological data regarding atrial fibrillation profile in Manado. We reviewed medical records of outpatients diagnosed with AF in the Department of Cardiology and Vascular Medicine, Prof. Dr. R.D. Kandou Hospital, Manado, from September 2012-February 2013. Relevant variables such as gender, age, co-morbids, echocardiography, and medical therapy were documented. The results showed that a total of 84 patients with AF were enrolled in the study. There were 42 males (50%) and 42 females (50%) with age ranges from 21 to 84 years (mean 60.74 years), of these 53 patients (63%) were ≥60 years and 31 patients (37%) <60 years. From the total 84 patients, 59 patients underwent echocardiography examinations: 39 patients (66.1%) had ejection fraction (EF) ≥55%; and 20 patients (33.9%) had EF <55% (mean 55.8%). Left atrial enlargement was found in 33 patients (55.9%) and thrombus was found in 13 patients (22%). Besides suffering from AF, 35 patients (41.7%) had hypertension, 40 (40.76%) had congestive heart failure, 20 (23.8%) had coronary artery disease, 21 (25%) had valvular heart diseases, 6 (7%) had pulmonary diseases, 5 (6%) had hyperthyroidism, and 1 (1.2%)  had no comorbid. Seventy patients (83.3%) were treated with bisoprolol, 2 (2.4%) with digoxin, 3 (3.5%) with amiodarone, 7 (8.4%) with bisoprolol and digoxin, and 2 (2.4%) with bisoprolol and amiodarone. Oral anticoagulant was used in 28 patients (33.3%), and aspirin in 40 patients (47.6%). Strokes were found in four patients (4.8%); one died due to stroke. Conclusion: The prevalence of AF was higher in the elderly. Congestive heart failure and hypertension were the most common co-morbids found, thus, greater awareness is needed. Bisoprolol was used as the highest proportion of treatment in AF patients, and the complication and mortality rates were low. Keywords: atrial fibrillation, comorbids, therapy.
